**The performance optimization system for AI agent harnesses. From an Anthropic hackathon winner.**

Not just configs. A complete system: skills, instincts, memory optimization, continuous learning, security scanning, and research-first development. Production-ready agents, skills, hooks, rules, MCP configurations, and legacy command shims evolved over 10+ months of intensive daily use building real products.

Works across **Claude Code**, **Codex**, **Cursor**, **OpenCode**, **Gemini**, **Zed**, **GitHub Copilot**, and other AI agent harnesses.

ECC v2.0.0-rc.1 adds the public Hermes operator story on top of that reusable layer: start with the [Hermes setup guide](docs/HERMES-SETUP.md), then review the [rc.1 release notes](docs/releases/2.0.0-rc.1/release-notes.md) and [cross-harness architecture](docs/architecture/cross-harness.md).

## What's New

### v2.0.0-rc.1 — Surface Refresh, Operator Workflows, and ECC 2.0 Alpha (Apr 2026)

- **Dashboard GUI** — New Tkinter-based desktop application (`ecc_dashboard.py` or `npm run dashboard`) with dark/light theme toggle, font customization, and project logo in header and taskbar.
- **Public surface synced to the live repo** — metadata, catalog counts, plugin manifests, and install-facing docs now match the actual OSS surface: 60 agents, 231 skills, and 75 legacy command shims.
- **Operator and outbound workflow expansion** — `brand-voice`, `social-graph-ranker`, `connections-optimizer`, `customer-billing-ops`, `ecc-tools-cost-audit`, `google-workspace-ops`, `project-flow-ops`, and `workspace-surface-audit` round out the operator lane.
- **Media and launch tooling** — `manim-video`, `remotion-video-creation`, and upgraded social publishing surfaces make technical explainers and launch content part of the same system.
- **Framework and product surface growth** — `nestjs-patterns`, richer Codex/OpenCode install surfaces, and expanded cross-harness packaging keep the repo usable beyond Claude Code alone.
- **ECC 2.0 alpha is in-tree** — the Rust control-plane prototype in `ecc2/` now builds locally and exposes `dashboard`, `start`, `sessions`, `status`, `stop`, `resume`, and `daemon` commands. It is usable as an alpha, not yet a general release.
- **Operator status snapshots** — `ecc status --markdown --write status.md` turns the local state store into a portable handoff covering readiness, active sessions, skill-run health, install health, pending governance events, and linked work items from Linear/GitHub/handoffs. Use `ecc work-items upsert ...` for manual entries, `ecc work-items sync-github --repo owner/repo` for PR/issue queue state, and `ecc status --exit-code` to fail automation when readiness needs attention.
- **Ecosystem hardening** — AgentShield, ECC Tools cost controls, billing portal work, and website refreshes continue to ship around the core plugin instead of drifting into separate silos.

### v1.9.0 — Selective Install & Language Expansion (Mar 2026)

- **Selective install architecture** — Manifest-driven install pipeline with `install-plan.js` and `install-apply.js` for targeted component installation. State store tracks what's installed and enables incremental updates.
- **6 new agents** — `typescript-reviewer`, `pytorch-build-resolver`, `java-build-resolver`, `java-reviewer`, `kotlin-reviewer`, `kotlin-build-resolver` expand language coverage to 10 languages.
- **New skills** — `pytorch-patterns` for deep learning workflows, `documentation-lookup` for API reference research, `bun-runtime` and `nextjs-turbopack` for modern JS toolchains, plus 8 operational domain skills and `mcp-server-patterns`.
- **Session & state infrastructure** — SQLite state store with query CLI, session adapters for structured recording, skill evolution foundation for self-improving skills.
- **Orchestration overhaul** — Harness audit scoring made deterministic, orchestration status and launcher compatibility hardened, observer loop prevention with 5-layer guard.
- **Observer reliability** — Memory explosion fix with throttling and tail sampling, sandbox access fix, lazy-start logic, and re-entrancy guard.
- **12 language ecosystems** — New rules for Java, PHP, Perl, Kotlin/Android/KMP, C++, and Rust join existing TypeScript, Python, Go, and common rules.
- **Community contributions** — Korean and Chinese translations, biome hook optimization, video processing skills, operational skills, PowerShell installer, Antigravity IDE support.
- **CI hardening** — 19 test failure fixes, catalog count enforcement, install manifest validation, and full test suite green.

### v1.8.0 — Harness Performance System (Mar 2026)

- **Harness-first release** — ECC is now explicitly framed as an agent harness performance system, not just a config pack.
- **Hook reliability overhaul** — SessionStart root fallback, Stop-phase session summaries, and script-based hooks replacing fragile inline one-liners.
- **Hook runtime controls** — `ECC_HOOK_PROFILE=minimal|standard|strict` and `ECC_DISABLED_HOOKS=...` for runtime gating without editing hook files.
- **New harness commands** — `/harness-audit`, `/loop-start`, `/loop-status`, `/quality-gate`, `/model-route`.
- **NanoClaw v2** — model routing, skill hot-load, session branch/search/export/compact/metrics.
- **Cross-harness parity** — behavior tightened across Claude Code, Cursor, OpenCode, and Codex app/CLI.
- **997 internal tests passing** — full suite green after hook/runtime refactor and compatibility updates.

### v1.7.0 — Cross-Platform Expansion & Presentation Builder (Feb 2026)

- **Codex app + CLI support** — Direct `AGENTS.md`-based Codex support, installer targeting, and Codex docs
- **`frontend-slides` skill** — Zero-dependency HTML presentation builder with PPTX conversion guidance and strict viewport-fit rules
- **5 new generic business/content skills** — `article-writing`, `content-engine`, `market-research`, `investor-materials`, `investor-outreach`
- **Broader tool coverage** — Cursor, Codex, and OpenCode support tightened so the same repo ships cleanly across all major harnesses
- **992 internal tests** — Expanded validation and regression coverage across plugin, hooks, skills, and packaging

### v1.6.0 — Codex CLI, AgentShield & Marketplace (Feb 2026)

- **Codex CLI support** — New `/codex-setup` command generates `codex.md` for OpenAI Codex CLI compatibility
- **7 new skills** — `search-first`, `swift-actor-persistence`, `swift-protocol-di-testing`, `regex-vs-llm-structured-text`, `content-hash-cache-pattern`, `cost-aware-llm-pipeline`, `skill-stocktake`
- **AgentShield integration** — `/security-scan` skill runs AgentShield directly from Claude Code; 1282 tests, 102 rules
- **GitHub Marketplace** — ECC Tools GitHub App live at [github.com/marketplace/ecc-tools](https://github.com/marketplace/ecc-tools) with free/pro/enterprise tiers
- **30+ community PRs merged** — Contributions from 30 contributors across 6 languages
- **978 internal tests** — Expanded validation suite across agents, skills, commands, hooks, and rules

### v1.4.1 — Bug Fix (Feb 2026)

- **Fixed instinct import content loss** — `parse_instinct_file()` was silently dropping all content after frontmatter (Action, Evidence, Examples sections) during `/instinct-import`. ([#148](https://github.com/affaan-m/everything-claude-code/issues/148), [#161](https://github.com/affaan-m/everything-claude-code/pull/161))

### v1.4.0 — Multi-Language Rules, Installation Wizard & PM2 (Feb 2026)

- **Interactive installation wizard** — New `configure-ecc` skill provides guided setup with merge/overwrite detection
- **PM2 & multi-agent orchestration** — 6 new commands (`/pm2`, `/multi-plan`, `/multi-execute`, `/multi-backend`, `/multi-frontend`, `/multi-workflow`) for managing complex multi-service workflows
- **Multi-language rules architecture** — Rules restructured from flat files into `common/` + `typescript/` + `python/` + `golang/` directories. Install only the languages you need
- **Chinese (zh-CN) translations** — Complete translation of all agents, commands, skills, and rules (80+ files)
- **GitHub Sponsors support** — Sponsor the project via GitHub Sponsors
- **Enhanced CONTRIBUTING.md** — Detailed PR templates for each contribution type

### v1.3.0 — OpenCode Plugin Support (Feb 2026)

## Quick Start

Get up and running in under 2 minutes:

### Pick one path only

Most Claude Code users should use exactly one install path:

- **Recommended default:** install the Claude Code plugin, then copy only the rule folders you actually want.
- **Use the manual installer only if** you want finer-grained control, want to avoid the plugin path entirely, or your Claude Code build has trouble resolving the self-hosted marketplace entry.
- **Do not stack install methods.** The most common broken setup is: `/plugin install` first, then `install.sh --profile full` or `npx ecc-install --profile full` afterward.

If you already layered multiple installs and things look duplicated, skip straight to [Reset / Uninstall ECC](#reset--uninstall-ecc).

### Low-context / no-hooks path

If hooks feel too global or you only want ECC's rules, agents, commands, and core workflow skills, skip the plugin and use the minimal manual profile:

```bash
./install.sh --profile minimal --target claude
```

```powershell
.\install.ps1 --profile minimal --target claude
# or
npx ecc-install --profile minimal --target claude
```

This profile intentionally excludes `hooks-runtime`.

If you want the normal core profile but need hooks off, use:

```bash
./install.sh --profile core --without baseline:hooks --target claude
```

Add hooks later only if you want runtime enforcement:

```bash
./install.sh --target claude --modules hooks-runtime
```

### Find the right components first

If you are not sure which ECC profile or component to install, ask the packaged advisor from any project:

```bash
npx ecc consult "security reviews" --target claude
```

It returns matching components, related profiles, and preview/install commands. Use the preview command before installing if you want to inspect the exact file plan.

For production ML/MLOps workflows, keep the install opt-in and component-scoped:

```bash
npx ecc consult "mlops training model deployment" --target claude
npx ecc install --profile minimal --target claude --with capability:machine-learning
```

### Step 1: Install the Plugin (Recommended)

> NOTE: The plugin is convenient, but the OSS installer below is still the most reliable path if your Claude Code build has trouble resolving self-hosted marketplace entries.

```bash
# Add marketplace
/plugin marketplace add https://github.com/affaan-m/everything-claude-code

# Install plugin
/plugin install ecc@ecc
```

### Naming + Migration Note

ECC now has three public identifiers, and they are not interchangeable:

- GitHub source repo: `affaan-m/everything-claude-code`
- Claude marketplace/plugin identifier: `ecc@ecc`
- npm package: `ecc-universal`

This is intentional. Anthropic marketplace/plugin installs are keyed by a canonical plugin identifier, so ECC uses `ecc@ecc` to keep tool names and slash-command namespaces short enough for strict Desktop/API validators. Older posts may still show the former long marketplace identifier; treat that as a legacy alias only. Separately, the npm package stayed on `ecc-universal`, so npm installs and marketplace installs intentionally use different names.

### Step 2: Install Rules Only If You Need Them

> WARNING: **Important:** Claude Code plugins cannot distribute `rules` automatically.
>
> If you already installed ECC via `/plugin install`, **do not run `./install.sh --profile full`, `.\install.ps1 --profile full`, or `npx ecc-install --profile full` afterward**. The plugin already loads ECC skills, commands, and hooks. Running the full installer after a plugin install copies those same surfaces into your user directories and can create duplicate skills plus duplicate runtime behavior.
>
> For plugin installs, manually copy only the `rules/` directories you want under `~/.claude/rules/ecc/`. Start with `rules/common` plus one language or framework pack you actually use. Do not copy every rules directory unless you explicitly want all of that context in Claude.
>
> Use the full installer only when you are doing a fully manual ECC install instead of the plugin path.
>
> If your local Claude setup was wiped or reset, that does not mean you need to repurchase ECC. Start with `node scripts/ecc.js list-installed`, then run `node scripts/ecc.js doctor` and `node scripts/ecc.js repair` before reinstalling anything. That usually restores ECC-managed files without rebuilding your setup. If the problem is account or marketplace access for ECC Tools, handle billing/account recovery separately.

```bash
# Clone the repo first
git clone https://github.com/affaan-m/everything-claude-code.git
cd everything-claude-code

# Install dependencies (pick your package manager)
npm install        # or: pnpm install | yarn install | bun install

# Plugin install path: copy only ECC rules into an ECC-owned namespace
mkdir -p ~/.claude/rules/ecc
cp -R rules/common ~/.claude/rules/ecc/
cp -R rules/typescript ~/.claude/rules/ecc/

# Fully manual ECC install path (use this instead of /plugin install)
# ./install.sh --profile full
```

```powershell
# Windows PowerShell

# Plugin install path: copy only ECC rules into an ECC-owned namespace
New-Item -ItemType Directory -Force -Path "$HOME/.claude/rules/ecc" | Out-Null
Copy-Item -Recurse rules/common "$HOME/.claude/rules/ecc/"
Copy-Item -Recurse rules/typescript "$HOME/.claude/rules/ecc/"

# Fully manual ECC install path (use this instead of /plugin install)
# .\install.ps1 --profile full
# npx ecc-install --profile full
```

For manual install instructions see the README in the `rules/` folder. When copying rules manually, copy the whole language directory (for example `rules/common` or `rules/golang`), not the files inside it, so relative references keep working and filenames do not collide.

### Fully manual install (Fallback)

Use this only if you are intentionally skipping the plugin path:

```bash
./install.sh --profile full
```

```powershell
.\install.ps1 --profile full
# or
npx ecc-install --profile full
```

If you choose this path, stop there. Do not also run `/plugin install`.

### Reset / Uninstall ECC

If ECC feels duplicated, intrusive, or broken, do not keep reinstalling it on top of itself.

- **Plugin path:** remove the plugin from Claude Code, then delete the specific rule folders you manually copied under `~/.claude/rules/ecc/`.
- **Manual installer / CLI path:** from the repo root, preview removal first:

```bash
node scripts/uninstall.js --dry-run
```

Then remove ECC-managed files:

```bash
node scripts/uninstall.js
```

You can also use the lifecycle wrapper:

```bash
node scripts/ecc.js list-installed
node scripts/ecc.js doctor
node scripts/ecc.js repair
node scripts/ecc.js uninstall --dry-run
```

ECC only removes files recorded in its install-state. It will not delete unrelated files it did not install.

If you stacked methods, clean up in this order:

1. Remove the Claude Code plugin install.
2. Run the ECC uninstall command from the repo root to remove install-state-managed files.
3. Delete any extra rule folders you copied manually and no longer want.
4. Reinstall once, using a single path.

### Step 3: Start Using

```bash
# Skills are the primary workflow surface.
# Existing slash-style command names still work while ECC migrates off commands/.

# Plugin install uses the canonical namespaced form
/ecc:plan "Add user authentication"

# Manual install keeps the shorter slash form:
# /plan "Add user authentication"

# Check available commands
/plugin list ecc@ecc
```

**That's it!** You now have access to 60 agents, 231 skills, and 75 legacy command shims.

### Dashboard GUI

Launch the desktop dashboard to visually explore ECC components:

```bash
npm run dashboard
# or
python3 ./ecc_dashboard.py
```

**Features:**
- Tabbed interface: Agents, Skills, Commands, Rules, Settings
- Dark/Light theme toggle
- Font customization (family & size)
- Project logo in header and taskbar
- Search and filter across all components

### Multi-model commands require additional setup

> WARNING: `multi-*` commands are **not** covered by the base plugin/rules install above.
>
> To use `/multi-plan`, `/multi-execute`, `/multi-backend`, `/multi-frontend`, and `/multi-workflow`, you must also install the `ccg-workflow` runtime.
>
> Initialize it with `npx ccg-workflow`.
>
> That runtime provides the external dependencies these commands expect, including:
> - `~/.claude/bin/codeagent-wrapper`
> - `~/.claude/.ccg/prompts/*`
>
> Without `ccg-workflow`, these `multi-*` commands will not run correctly.

---

## Cross-Platform Support

This plugin now fully supports **Windows, macOS, and Linux**, alongside tight integration across major IDEs (Cursor, Zed, OpenCode, Antigravity) and CLI harnesses. All hooks and scripts have been rewritten in Node.js for maximum compatibility.

### Package Manager Detection

The plugin automatically detects your preferred package manager (npm, pnpm, yarn, or bun) with the following priority:

1. **Environment variable**: `CLAUDE_PACKAGE_MANAGER`
2. **Project config**: `.claude/package-manager.json`
3. **package.json**: `packageManager` field
4. **Lock file**: Detection from package-lock.json, yarn.lock, pnpm-lock.yaml, or bun.lockb
5. **Global config**: `~/.claude/package-manager.json`
6. **Fallback**: First available package manager

To set your preferred package manager:

```bash
# Via environment variable
export CLAUDE_PACKAGE_MANAGER=pnpm

# Via global config
node scripts/setup-package-manager.js --global pnpm

# Via project config
node scripts/setup-package-manager.js --project bun

# Detect current setting
node scripts/setup-package-manager.js --detect
```

Or use the `/setup-pm` command in Claude Code.

### Hook Runtime Controls

Use runtime flags to tune strictness or disable specific hooks temporarily:

```bash
# Hook strictness profile (default: standard)
export ECC_HOOK_PROFILE=standard

# Comma-separated hook IDs to disable
export ECC_DISABLED_HOOKS="pre:bash:tmux-reminder,post:edit:typecheck"

# Cap SessionStart additional context (default: 8000 chars)
export ECC_SESSION_START_MAX_CHARS=4000

# Disable SessionStart additional context entirely for low-context/local-model setups
export ECC_SESSION_START_CONTEXT=off

# Keep context/scope/loop warnings but suppress API-rate cost estimates
export ECC_CONTEXT_MONITOR_COST_WARNINGS=off
```

Windows PowerShell:

```powershell
[Environment]::SetEnvironmentVariable('ECC_CONTEXT_MONITOR_COST_WARNINGS', 'off', 'User')
```

## Ecosystem Tools

### Skill Creator

Two ways to generate Claude Code skills from your repository:

#### Option A: Local Analysis (Built-in)

Use the `/skill-create` command for local analysis without external services:

```bash
/skill-create                    # Analyze current repo
/skill-create --instincts        # Also generate instincts for continuous-learning-v2
```

This analyzes your git history locally and generates SKILL.md files.

#### Option B: GitHub App (Advanced)

For advanced features (10k+ commits, auto-PRs, team sharing):

[Install GitHub App](https://github.com/apps/skill-creator) | [ecc.tools](https://ecc.tools)

```bash
# Comment on any issue:
/skill-creator analyze

# Or auto-triggers on push to default branch
```

Both options create:
- **SKILL.md files** - Ready-to-use skills for Claude Code
- **Instinct collections** - For continuous-learning-v2
- **Pattern extraction** - Learns from your commit history

### AgentShield — Security Auditor

> Built at the Claude Code Hackathon (Cerebral Valley x Anthropic, Feb 2026). 1282 tests, 98% coverage, 102 static analysis rules.

Scan your Claude Code configuration for vulnerabilities, misconfigurations, and injection risks.

```bash
# Quick scan (no install needed)
npx ecc-agentshield scan

# Auto-fix safe issues
npx ecc-agentshield scan --fix

# Deep analysis with three Opus 4.6 agents
npx ecc-agentshield scan --opus --stream

# Generate secure config from scratch
npx ecc-agentshield init
```

**What it scans:** CLAUDE.md, settings.json, MCP configs, hooks, agent definitions, and skills across 5 categories — secrets detection (14 patterns), permission auditing, hook injection analysis, MCP server risk profiling, and agent config review.

**The `--opus` flag** runs three Claude Opus 4.6 agents in a red-team/blue-team/auditor pipeline. The attacker finds exploit chains, the defender evaluates protections, and the auditor synthesizes both into a prioritized risk assessment. Adversarial reasoning, not just pattern matching.

**Output formats:** Terminal (color-graded A-F), JSON (CI pipelines), Markdown, HTML. Exit code 2 on critical findings for build gates.

Use `/security-scan` in Claude Code to run it, or add to CI with the [GitHub Action](https://github.com/affaan-m/agentshield).

[GitHub](https://github.com/affaan-m/agentshield) | [npm](https://www.npmjs.com/package/ecc-agentshield)

### Continuous Learning v2

The instinct-based learning system automatically learns your patterns:

```bash
/instinct-status        # Show learned instincts with confidence
/instinct-import <file> # Import instincts from others
/instinct-export        # Export your instincts for sharing
/evolve                 # Cluster related instincts into skills
```

See `skills/continuous-learning-v2/` for full documentation.
Keep `continuous-learning/` only when you explicitly want the legacy v1 Stop-hook learned-skill flow.

---

## Requirements

### Claude Code CLI Version

**Minimum version: v2.1.0 or later**

This plugin requires Claude Code CLI v2.1.0+ due to changes in how the plugin system handles hooks.

Check your version:
```bash
claude --version
```

### Important: Hooks Auto-Loading Behavior

> WARNING: **For Contributors:** Do NOT add a `"hooks"` field to `.claude-plugin/plugin.json`. This is enforced by a regression test.

Claude Code v2.1+ **automatically loads** `hooks/hooks.json` from any installed plugin by convention. Explicitly declaring it in `plugin.json` causes a duplicate detection error:

```
Duplicate hooks file detected: ./hooks/hooks.json resolves to already-loaded file
```

**History:** This has caused repeated fix/revert cycles in this repo ([#29](https://github.com/affaan-m/everything-claude-code/issues/29), [#52](https://github.com/affaan-m/everything-claude-code/issues/52), [#103](https://github.com/affaan-m/everything-claude-code/issues/103)). The behavior changed between Claude Code versions, leading to confusion. We now have a regression test to prevent this from being reintroduced.

## Installation

### Option 1: Install as Plugin (Recommended)

The easiest way to use this repo - install as a Claude Code plugin:

```bash
# Add this repo as a marketplace
/plugin marketplace add https://github.com/affaan-m/everything-claude-code

# Install the plugin
/plugin install ecc@ecc
```

Or add directly to your `~/.claude/settings.json`:

```json
{
  "extraKnownMarketplaces": {
    "ecc": {
      "source": {
        "source": "github",
        "repo": "affaan-m/everything-claude-code"
      }
    }
  },
  "enabledPlugins": {
    "ecc@ecc": true
  }
}
```

This gives you instant access to all commands, agents, skills, and hooks.

> **Note:** The Claude Code plugin system does not support distributing `rules` via plugins ([upstream limitation](https://code.claude.com/docs/en/plugins-reference)). You need to install rules manually:
>
> ```bash
> # Clone the repo first
> git clone https://github.com/affaan-m/everything-claude-code.git
>
> # Option A: User-level rules (applies to all projects)
> mkdir -p ~/.claude/rules/ecc
> cp -r everything-claude-code/rules/common ~/.claude/rules/ecc/
> cp -r everything-claude-code/rules/typescript ~/.claude/rules/ecc/   # pick your stack
> cp -r everything-claude-code/rules/python ~/.claude/rules/ecc/
> cp -r everything-claude-code/rules/golang ~/.claude/rules/ecc/
> cp -r everything-claude-code/rules/php ~/.claude/rules/ecc/
>
> # Option B: Project-level rules (applies to current project only)
> mkdir -p .claude/rules/ecc
> cp -r everything-claude-code/rules/common .claude/rules/ecc/
> cp -r everything-claude-code/rules/typescript .claude/rules/ecc/     # pick your stack
> ```

---

### Option 2: Manual Installation

If you prefer manual control over what's installed:

```bash
# Clone the repo
git clone https://github.com/affaan-m/everything-claude-code.git

# Copy agents to your Claude config
cp everything-claude-code/agents/*.md ~/.claude/agents/

# Copy rules directories (common + language-specific)
mkdir -p ~/.claude/rules/ecc
cp -r everything-claude-code/rules/common ~/.claude/rules/ecc/
cp -r everything-claude-code/rules/typescript ~/.claude/rules/ecc/   # pick your stack
cp -r everything-claude-code/rules/python ~/.claude/rules/ecc/
cp -r everything-claude-code/rules/golang ~/.claude/rules/ecc/
cp -r everything-claude-code/rules/php ~/.claude/rules/ecc/
cp -r everything-claude-code/rules/arkts ~/.claude/rules/ecc/

# Copy skills first (primary workflow surface)
# Recommended (new users): core/general skills only
mkdir -p ~/.claude/skills/ecc
cp -r everything-claude-code/.agents/skills/* ~/.claude/skills/ecc/
cp -r everything-claude-code/skills/search-first ~/.claude/skills/ecc/

# Optional: add niche/framework-specific skills only when needed
# for s in django-patterns django-tdd laravel-patterns springboot-patterns quarkus-patterns; do
# cp -r everything-claude-code/skills/$s ~/.claude/skills/ecc/
# done

# Optional: keep maintained slash-command compatibility during migration
mkdir -p ~/.claude/commands
cp everything-claude-code/commands/*.md ~/.claude/commands/

# Retired shims live in legacy-command-shims/commands/.
# Copy individual files from there only if you still need old names such as /tdd.
```

#### Install hooks

Do not copy the raw repo `hooks/hooks.json` into `~/.claude/settings.json` or `~/.claude/hooks/hooks.json`. That file is plugin/repo-oriented and is meant to be installed through the ECC installer or loaded as a plugin, so raw copying is not a supported manual install path.

Use the installer to install only the Claude hook runtime so command paths are rewritten correctly:

```bash
# macOS / Linux
bash ./install.sh --target claude --modules hooks-runtime
```

```powershell
# Windows PowerShell
pwsh -File .\install.ps1 --target claude --modules hooks-runtime
```

That writes resolved hooks to `~/.claude/hooks/hooks.json` and leaves any existing `~/.claude/settings.json` untouched.

If you installed ECC via `/plugin install`, do not copy those hooks into `settings.json`. Claude Code v2.1+ already auto-loads plugin `hooks/hooks.json`, and duplicating them in `settings.json` causes duplicate execution and cross-platform hook conflicts.

Windows note: the Claude config directory is `%USERPROFILE%\\.claude`, not `~/claude`.

#### Configure MCPs

Claude plugin installs intentionally do not auto-enable ECC's bundled MCP server definitions. This avoids overlong plugin MCP tool names on strict third-party gateways while keeping manual MCP setup available.

Use Claude Code's `/mcp` command or CLI-managed MCP setup for live Claude Code server changes. Use `/mcp` for Claude Code runtime disables; Claude Code persists those choices in `~/.claude.json`.

For repo-local MCP access, copy desired MCP server definitions from `mcp-configs/mcp-servers.json` into a project-scoped `.mcp.json`.

If you already run your own copies of ECC-bundled MCPs, set:

```bash
export ECC_DISABLED_MCPS="github,context7,exa,playwright,sequential-thinking,memory"
```

ECC-managed install and Codex sync flows will skip or remove those bundled servers instead of re-adding duplicates. `ECC_DISABLED_MCPS` is an ECC install/sync filter, not a live Claude Code toggle.

**Important:** Replace `YOUR_*_HERE` placeholders with your actual API keys.

## Key Concepts

### Agents

Subagents handle delegated tasks with limited scope. Example:

```markdown
---
name: code-reviewer
description: Reviews code for quality, security, and maintainability
tools: ["Read", "Grep", "Glob", "Bash"]
model: opus
---

You are a senior code reviewer...
```

### Skills

Skills are the primary workflow surface. They can be invoked directly, suggested automatically, and reused by agents. ECC still ships maintained `commands/` during migration, while retired short-name shims live under `legacy-command-shims/` for explicit opt-in only. New workflow development should land in `skills/` first.

```markdown
# TDD Workflow

1. Define interfaces first
2. Write failing tests (RED)
3. Implement minimal code (GREEN)
4. Refactor (IMPROVE)
5. Verify 80%+ coverage
```

### Hooks

Hooks fire on tool events. Example - warn about console.log:

```json
{
  "matcher": "tool == \"Edit\" && tool_input.file_path matches \"\\\\.(ts|tsx|js|jsx)$\"",
  "hooks": [{
    "type": "command",
    "command": "#!/bin/bash\ngrep -n 'console\\.log' \"$file_path\" && echo '[Hook] Remove console.log' >&2"
  }]
}
```

### Rules

Rules are always-follow guidelines, organized into `common/` (language-agnostic) + language-specific directories:

```
rules/
  common/          # Universal principles (always install)
  typescript/      # TS/JS specific patterns and tools
  python/          # Python specific patterns and tools
  golang/          # Go specific patterns and tools
  swift/           # Swift specific patterns and tools
  php/             # PHP specific patterns and tools
  arkts/           # HarmonyOS / ArkTS patterns and constraints
```

See [`rules/README.md`](rules/README.md) for installation and structure details.

### Common Workflows

Slash forms below are shown where they remain part of the maintained command surface. Retired short-name shims such as `/tdd` and `/eval` live in `legacy-command-shims/` for explicit opt-in only.

**Starting a new feature:**
```
/ecc:plan "Add user authentication with OAuth"
                                              → planner creates implementation blueprint
tdd-workflow skill                            → tdd-guide enforces write-tests-first
/code-review                                  → code-reviewer checks your work
```

**Fixing a bug:**
```
tdd-workflow skill                            → tdd-guide: write a failing test that reproduces it
                                              → implement the fix, verify test passes
/code-review                                  → code-reviewer: catch regressions
```

**Preparing for production:**
```
/security-scan                                → security-reviewer: OWASP Top 10 audit
e2e-testing skill                             → e2e-runner: critical user flow tests
/test-coverage                                → verify 80%+ coverage
```

## FAQ

<details>
<summary><b>How do I check which agents/commands are installed?</b></summary>

```bash
/plugin list ecc@ecc
```

This shows all available agents, commands, and skills from the plugin.
</details>

<details>
<summary><b>My hooks aren't working / I see "Duplicate hooks file" errors</b></summary>

This is the most common issue. **Do NOT add a `"hooks"` field to `.claude-plugin/plugin.json`.** Claude Code v2.1+ automatically loads `hooks/hooks.json` from installed plugins. Explicitly declaring it causes duplicate detection errors. See [#29](https://github.com/affaan-m/everything-claude-code/issues/29), [#52](https://github.com/affaan-m/everything-claude-code/issues/52), [#103](https://github.com/affaan-m/everything-claude-code/issues/103).
</details>

<details>
<summary><b>Can I use ECC with Claude Code on a custom API endpoint or model gateway?</b></summary>

Yes. ECC does not hardcode Anthropic-hosted transport settings. It runs locally through Claude Code's normal CLI/plugin surface, so it works with:

- Anthropic-hosted Claude Code
- Official Claude Code gateway setups using `ANTHROPIC_BASE_URL` and `ANTHROPIC_AUTH_TOKEN`
- Compatible custom endpoints that speak the Anthropic API Claude Code expects

Minimal example:

```bash
export ANTHROPIC_BASE_URL=https://your-gateway.example.com
export ANTHROPIC_AUTH_TOKEN=your-token
claude
```

If your gateway remaps model names, configure that in Claude Code rather than in ECC. ECC's hooks, skills, commands, and rules are model-provider agnostic once the `claude` CLI is already working.

Official references:
- [Claude Code LLM gateway docs](https://docs.anthropic.com/en/docs/claude-code/llm-gateway)
- [Claude Code model configuration docs](https://docs.anthropic.com/en/docs/claude-code/model-config)

</details>

<details>
<summary><b>My context window is shrinking / Claude is running out of context</b></summary>

Too many MCP servers eat your context. Each MCP tool description consumes tokens from your 200k window, potentially reducing it to ~70k. SessionStart context is capped at 8000 characters by default; lower it with `ECC_SESSION_START_MAX_CHARS=4000` or disable it with `ECC_SESSION_START_CONTEXT=off` for local-model or low-context setups.

**Fix:** Disable unused MCPs from Claude Code with `/mcp`. Claude Code writes those runtime choices to `~/.claude.json`; `.claude/settings.json` and `.claude/settings.local.json` are not reliable toggles for already-loaded MCP servers.

Keep under 10 MCPs enabled and under 80 tools active.
</details>

<details>
<summary><b>Can I use only some components (e.g., just agents)?</b></summary>

Yes. Use Option 2 (manual installation) and copy only what you need:

```bash
# Just agents
cp everything-claude-code/agents/*.md ~/.claude/agents/

# Just rules
mkdir -p ~/.claude/rules/ecc/
cp -r everything-claude-code/rules/common ~/.claude/rules/ecc/
```

Each component is fully independent.
</details>

<details>
<summary><b>Does this work with Cursor / OpenCode / Codex / Antigravity / GitHub Copilot?</b></summary>

Yes. ECC is cross-platform:
- **Cursor**: Pre-translated configs in `.cursor/`. See [Cursor IDE Support](#cursor-ide-support).
- **Gemini CLI**: Experimental project-local support via `.gemini/GEMINI.md` and shared installer plumbing.
- **OpenCode**: Full plugin support in `.opencode/`. See [OpenCode Support](#opencode-support).

## Cursor IDE Support

ECC provides Cursor IDE support with hooks, rules, agents, skills, commands, and MCP configs adapted for Cursor's project layout.

### Quick Start (Cursor)

```bash
# macOS/Linux
./install.sh --target cursor typescript
./install.sh --target cursor python golang swift php
```

```powershell
# Windows PowerShell
.\install.ps1 --target cursor typescript
.\install.ps1 --target cursor python golang swift php
```

### What's Included

| Component | Count | Details |
|-----------|-------|---------|
| Hook Events | 15 | sessionStart, beforeShellExecution, afterFileEdit, beforeMCPExecution, beforeSubmitPrompt, and 10 more |
| Hook Scripts | 16 | Thin Node.js scripts delegating to `scripts/hooks/` via shared adapter |
| Rules | 34 | 9 common (alwaysApply) + 25 language-specific (TypeScript, Python, Go, Swift, PHP) |
| Agents | 48 | `.cursor/agents/ecc-*.md` when installed; prefixed to avoid collisions with user or marketplace agents |
| Skills | Shared + Bundled | `.cursor/skills/` for translated additions |
| Commands | Shared | `.cursor/commands/` if installed |
| MCP Config | Shared | `.cursor/mcp.json` if installed |

### Cursor Loading Notes

ECC does not install root `AGENTS.md` into `.cursor/`. Cursor treats nested `AGENTS.md` files as directory context, so copying ECC's repo identity into a host project would pollute that project.

Cursor-native loading behavior can vary by Cursor build. ECC installs agents as `.cursor/agents/ecc-*.md`; if your Cursor build does not expose project agents, those files still work as explicit reference definitions instead of hidden global prompt context.

### Hook Architecture (DRY Adapter Pattern)

Cursor has **more hook events than Claude Code** (20 vs 8). The `.cursor/hooks/adapter.js` module transforms Cursor's stdin JSON to Claude Code's format, allowing existing `scripts/hooks/*.js` to be reused without duplication.

```
Cursor stdin JSON → adapter.js → transforms → scripts/hooks/*.js
                                              (shared with Claude Code)
```

Key hooks:
- **beforeShellExecution** — Blocks dev servers outside tmux (exit 2), git push review
- **afterFileEdit** — Auto-format + TypeScript check + console.log warning
- **beforeSubmitPrompt** — Detects secrets (sk-, ghp_, AKIA patterns) in prompts
- **beforeTabFileRead** — Blocks Tab from reading .env, .key, .pem files (exit 2)
- **beforeMCPExecution / afterMCPExecution** — MCP audit logging

### Rules Format

Cursor rules use YAML frontmatter with `description`, `globs`, and `alwaysApply`:

```yaml
---
description: "TypeScript coding style extending common rules"
globs: ["**/*.ts", "**/*.tsx", "**/*.js", "**/*.jsx"]
alwaysApply: false
---
```

---

## Codex macOS App + CLI Support

ECC provides **first-class Codex support** for both the macOS app and CLI, with a reference configuration, Codex-specific AGENTS.md supplement, and shared skills.

### Quick Start (Codex App + CLI)

```bash
# Run Codex CLI in the repo — AGENTS.md and .codex/ are auto-detected
codex

# Automatic setup: sync ECC assets (AGENTS.md, skills, MCP servers) into ~/.codex
npm install && bash scripts/sync-ecc-to-codex.sh
# or: pnpm install && bash scripts/sync-ecc-to-codex.sh
# or: yarn install && bash scripts/sync-ecc-to-codex.sh
# or: bun install && bash scripts/sync-ecc-to-codex.sh

# Or manually: copy the reference config to your home directory
cp .codex/config.toml ~/.codex/config.toml
```

The sync script safely merges ECC MCP servers into your existing `~/.codex/config.toml` using an **add-only** strategy — it never removes or modifies your existing servers. Run with `--dry-run` to preview changes, or `--update-mcp` to force-refresh ECC servers to the latest recommended config.

For Context7, ECC uses the canonical Codex section name `[mcp_servers.context7]` while still launching the `@upstash/context7-mcp` package. If you already have a legacy `[mcp_servers.context7-mcp]` entry, `--update-mcp` migrates it to the canonical section name.

Codex macOS app:
- Open this repository as your workspace.
- The root `AGENTS.md` is auto-detected.
- `.codex/config.toml` and `.codex/agents/*.toml` work best when kept project-local.
- The reference `.codex/config.toml` intentionally does not pin `model` or `model_provider`, so Codex uses its own current default unless you override it.
- Optional: copy `.codex/config.toml` to `~/.codex/config.toml` for global defaults; keep the multi-agent role files project-local unless you also copy `.codex/agents/`.

### What's Included

| Component | Count | Details |
|-----------|-------|---------|
| Config | 1 | `.codex/config.toml` — top-level approvals/sandbox/web_search, MCP servers, notifications, profiles |
| AGENTS.md | 2 | Root (universal) + `.codex/AGENTS.md` (Codex-specific supplement) |
| Skills | 32 | `.agents/skills/` — SKILL.md + agents/openai.yaml per skill |
| MCP Servers | 6 | GitHub, Context7, Exa, Memory, Playwright, Sequential Thinking (7 with Supabase via `--update-mcp` sync) |
| Profiles | 2 | `strict` (read-only sandbox) and `yolo` (full auto-approve) |
| Agent Roles | 3 | `.codex/agents/` — explorer, reviewer, docs-researcher |

### Skills

Skills at `.agents/skills/` are auto-loaded by Codex:

Canonical Anthropic skills such as `claude-api`, `frontend-design`, and `skill-creator` are intentionally not re-bundled here. Install those from [`anthropics/skills`](https://github.com/anthropics/skills) when you want the official versions.

| Skill | Description |
|-------|-------------|
| agent-introspection-debugging | Debug agent behavior, routing, and prompt boundaries |

| verification-loop | Build, test, lint, typecheck, security |
| video-editing | AI-assisted video editing workflows with FFmpeg and Remotion |
| x-api | X/Twitter API integration for posting and analytics |

### Key Limitation

Codex does **not yet provide Claude-style hook execution parity**. ECC enforcement there is instruction-based via `AGENTS.md`, optional `model_instructions_file` overrides, and sandbox/approval settings.

### Multi-Agent Support

Current Codex builds support stable multi-agent workflows.

- Enable `features.multi_agent = true` in `.codex/config.toml`
- Define roles under `[agents.<name>]`
- Point each role at a file under `.codex/agents/`
- Use `/agent` in the CLI to inspect or steer child agents

ECC ships three sample role configs:

| Role | Purpose |
|------|---------|
| `explorer` | Read-only codebase evidence gathering before edits |
| `reviewer` | Correctness, security, and missing-test review |
| `docs_researcher` | Documentation and API verification before release/docs changes |

---

## Zed Support

ECC provides Zed project support through a conservative `.zed` adapter for project-local settings, flattened rules, agents, commands, and skills.

```bash
./install.sh --profile minimal --target zed
```

```powershell
.\install.ps1 --profile minimal --target zed
```

The adapter writes ECC-managed files under `.zed/` and keeps BYOK/OpenRouter credentials out of the repo. Configure Zed account or API keys through Zed's own settings UI or your local user settings.

---

## OpenCode Support

ECC provides **full OpenCode support** including plugins and hooks.

### Quick Start

```bash
# Install OpenCode
npm install -g opencode

# Run in the repository root
opencode
```

The configuration is automatically detected from `.opencode/opencode.json`.

### Feature Parity

| Feature | Claude Code | OpenCode | Status |
|---------|-------------|----------|--------|
| Agents | PASS: 60 agents | PASS: 12 agents | **Claude Code leads** |
| Commands | PASS: 75 commands | PASS: 35 commands | **Claude Code leads** |
| Skills | PASS: 231 skills | PASS: 37 skills | **Claude Code leads** |
| Hooks | PASS: 8 event types | PASS: 11 events | **OpenCode has more!** |
| Rules | PASS: 29 rules | PASS: 13 instructions | **Claude Code leads** |
| MCP Servers | PASS: 14 servers | PASS: Full | **Full parity** |
| Custom Tools | PASS: Via hooks | PASS: 6 native tools | **OpenCode is better** |

### Hook Support via Plugins

OpenCode's plugin system is MORE sophisticated than Claude Code with 20+ event types:

| Claude Code Hook | OpenCode Plugin Event |
|-----------------|----------------------|
| PreToolUse | `tool.execute.before` |
| PostToolUse | `tool.execute.after` |
| Stop | `session.idle` |
| SessionStart | `session.created` |
| SessionEnd | `session.deleted` |

**Additional OpenCode events**: `file.edited`, `file.watcher.updated`, `message.updated`, `lsp.client.diagnostics`, `tui.toast.show`, and more.

### Maintained Slash Entries

| Command | Description |
|---------|-------------|
| `/plan` | Create implementation plan |
| `/code-review` | Review code changes |
| `/build-fix` | Fix build errors |

| `/instinct-export` | Export instincts |
| `/evolve` | Cluster instincts into skills |
| `/promote` | Promote project instincts to global scope |
| `/projects` | List known projects and instinct stats |

| `/quality-gate` | Run quality gate checks for paths or entire repo |
| `/model-route` | Route tasks to models by complexity and budget |

### Plugin Installation

**Option 1: Use directly**
```bash
cd everything-claude-code
opencode
```

**Option 2: Install as npm package**
```bash
npm install ecc-universal
```

Then add to your `opencode.json`:
```json
{
  "plugin": ["ecc-universal"]
}
```

That npm plugin entry enables ECC's published OpenCode plugin module (hooks/events and plugin tools).
It does **not** automatically add ECC's full command/agent/instruction catalog to your project config.

For the full ECC OpenCode setup, either:
- run OpenCode inside this repository, or
- copy the bundled `.opencode/` config assets into your project and wire the `instructions`, `agent`, and `command` entries in `opencode.json`

### Documentation

- **Migration Guide**: `.opencode/MIGRATION.md`
- **OpenCode Plugin README**: `.opencode/README.md`
- **Consolidated Rules**: `.opencode/instructions/INSTRUCTIONS.md`
- **LLM Documentation**: `llms.txt` (complete OpenCode docs for LLMs)

## GitHub Copilot Support

ECC provides **GitHub Copilot support** for VS Code via Copilot Chat's native instruction and prompt file system — no extra tooling required.

### What's Included

| Component | File | Purpose |
|-----------|------|---------|
| Core instructions | `.github/copilot-instructions.md` | Always-loaded rules: coding style, security, testing, git workflow |
| VS Code settings | `.vscode/settings.json` | Per-task instruction files for code gen, test gen, review, and commit messages |
| Plan prompt | `.github/prompts/plan.prompt.md` | Phased implementation planning |
| TDD prompt | `.github/prompts/tdd.prompt.md` | Red-Green-Improve cycle |
| Code review prompt | `.github/prompts/code-review.prompt.md` | Quality and security review |
| Security review prompt | `.github/prompts/security-review.prompt.md` | Deep OWASP-aligned security analysis |
| Build fix prompt | `.github/prompts/build-fix.prompt.md` | Systematic build and CI error resolution |
| Refactor prompt | `.github/prompts/refactor.prompt.md` | Dead code cleanup and simplification |

### Quick Start (GitHub Copilot)

The files are already in place — open any repo that contains this project and GitHub Copilot Chat will automatically pick up `.github/copilot-instructions.md`.
The committed `.vscode/settings.json` enables `chat.promptFiles` so VS Code can load the reusable prompts from `.github/prompts/`.

To use the workflow prompts in Copilot Chat:
1. Open the Copilot Chat panel in VS Code.
2. Click the **paperclip / attach** icon and select **Prompt...**, or type `/` and choose a prompt.
3. Select the prompt (e.g. `plan`, `tdd`, `code-review`).

### How It Works

GitHub Copilot in VS Code reads two types of files automatically:

- **`.github/copilot-instructions.md`** — repository-level instructions, always injected into every Copilot Chat request. Contains ECC's core coding standards, security checklist, testing requirements, and git workflow.
- **`.github/prompts/*.prompt.md`** — reusable prompt files users invoke on demand. Each prompt walks Copilot through a specific ECC workflow (plan → TDD → review → ship).

The **`.vscode/settings.json`** adds per-task instruction overlays so Copilot receives the right context depending on whether you are generating code, writing tests, reviewing a selection, or drafting a commit message.

### Feature Coverage

| ECC Feature | Copilot equivalent |
|-------------|-------------------|
| Coding standards | Always-on via `copilot-instructions.md` |
| Security checklist | Always-on + `security-review` prompt |
| Testing / TDD | Always-on + `tdd` prompt |
| Implementation planning | `plan` prompt |
| Code review | `code-review` prompt |
| Build error resolution | `build-fix` prompt |
| Refactoring | `refactor` prompt |
| Commit message format | Per-task instruction in `settings.json` |
| Hooks / automation | Not supported (Copilot has no hook system) |
| Agents / delegation | Not supported (Copilot has no subagent API) |

### Limitations

GitHub Copilot does not have a hook system or a subagent API, so ECC's hook automations (auto-format, TypeScript check, session persistence, dev-server guard) and agent delegation are unavailable. The instruction and prompt layer still brings the full ECC coding philosophy — standards, security, TDD, and workflow — into every Copilot Chat session.

---

## Cross-Tool Feature Parity

ECC is the **first plugin to maximize every major AI coding tool**. Here's how each harness compares:

| Feature | Claude Code | Cursor IDE | Codex CLI | OpenCode | GitHub Copilot |
|---------|------------|------------|-----------|----------|----------------|
| **Agents** | 60 | Shared (AGENTS.md) | Shared (AGENTS.md) | 12 | N/A |
| **Commands** | 75 | Shared | Instruction-based | 35 | 6 prompts |
| **Skills** | 231 | Shared | 10 (native format) | 37 | Via instructions |
| **Hook Events** | 8 types | 15 types | None yet | 11 types | None |
| **Hook Scripts** | 20+ scripts | 16 scripts (DRY adapter) | N/A | Plugin hooks | N/A |
| **Rules** | 34 (common + lang) | 34 (YAML frontmatter) | Instruction-based | 13 instructions | 1 always-on file |
| **Custom Tools** | Via hooks | Via hooks | N/A | 6 native tools | N/A |
| **MCP Servers** | 14 | Shared (mcp.json) | 7 (auto-merged via TOML parser) | Full | N/A |
| **Config Format** | settings.json | hooks.json + rules/ | config.toml | opencode.json | copilot-instructions.md + settings.json |
| **Context File** | CLAUDE.md + AGENTS.md | AGENTS.md | AGENTS.md | AGENTS.md | copilot-instructions.md |
| **Secret Detection** | Hook-based | beforeSubmitPrompt hook | Sandbox-based | Hook-based | Instruction-based |
| **Auto-Format** | PostToolUse hook | afterFileEdit hook | N/A | file.edited hook | N/A |
| **Version** | Plugin | Plugin | Reference config | 2.0.0-rc.1 | Instruction layer |

**Key architectural decisions:**
- **AGENTS.md** at root is the universal cross-tool file (read by Claude Code, Cursor, Codex, and OpenCode — GitHub Copilot uses `.github/copilot-instructions.md` instead)
- **DRY adapter pattern** lets Cursor reuse Claude Code's hook scripts without duplication
- **Skills format** (SKILL.md with YAML frontmatter) works across Claude Code, Codex, and OpenCode
- Codex's lack of hooks is compensated by `AGENTS.md`, optional `model_instructions_file` overrides, and sandbox permissions

---

## Background

I've been using Claude Code since the experimental rollout. Won the Anthropic x Forum Ventures hackathon in Sep 2025 with [@DRodriguezFX](https://x.com/DRodriguezFX) — built [zenith.chat](https://zenith.chat) entirely using Claude Code.

These configs are battle-tested across multiple production applications.

---

## Token Optimization

Claude Code usage can be expensive if you don't manage token consumption. These settings significantly reduce costs without sacrificing quality.

### Recommended Settings

Add to `~/.claude/settings.json`:

```json
{
  "model": "sonnet",
  "env": {
    "MAX_THINKING_TOKENS": "10000",
    "CLAUDE_AUTOCOMPACT_PCT_OVERRIDE": "50"
  }
}
```

| Setting | Default | Recommended | Impact |
|---------|---------|-------------|--------|
| `model` | opus | **sonnet** | ~60% cost reduction; handles 80%+ of coding tasks |
| `MAX_THINKING_TOKENS` | 31,999 | **10,000** | ~70% reduction in hidden thinking cost per request |
| `CLAUDE_AUTOCOMPACT_PCT_OVERRIDE` | 95 | **50** | Compacts earlier — better quality in long sessions |
| `ECC_CONTEXT_MONITOR_COST_WARNINGS` | on | **off for subscription users** | Suppresses agent-facing API-rate estimate warnings while keeping context/scope/loop warnings |

Switch to Opus only when you need deep architectural reasoning:
```
/model opus
```

### Daily Workflow Commands

| Command | When to Use |
|---------|-------------|
| `/model sonnet` | Default for most tasks |
| `/model opus` | Complex architecture, debugging, deep reasoning |
| `/clear` | Between unrelated tasks (free, instant reset) |
| `/compact` | At logical task breakpoints (research done, milestone complete) |
| `/cost` | Monitor token spending during session |

If you use a Claude subscription and the context monitor's API-rate estimates are not useful, set `ECC_CONTEXT_MONITOR_COST_WARNINGS=off`. This only suppresses the agent-facing cost warnings; it does not disable context exhaustion, scope, or loop warnings.

### Strategic Compaction

The `strategic-compact` skill (included in this plugin) suggests `/compact` at logical breakpoints instead of relying on auto-compaction at 95% context. See `skills/strategic-compact/SKILL.md` for the full decision guide.

**When to compact:**
- After research/exploration, before implementation
- After completing a milestone, before starting the next
- After debugging, before continuing feature work
- After a failed approach, before trying a new one

**When NOT to compact:**
- Mid-implementation (you'll lose variable names, file paths, partial state)

### Context Window Management

**Critical:** Don't enable all MCPs at once. Each MCP tool description consumes tokens from your 200k window, potentially reducing it to ~70k.

- Keep under 10 MCPs enabled per project
- Keep under 80 tools active
- Use `/mcp` to disable unused Claude Code MCP servers; those runtime choices persist in `~/.claude.json`
- Use `ECC_DISABLED_MCPS` only to filter ECC-generated MCP configs during install/sync flows

### Agent Teams Cost Warning

Agent Teams spawns multiple context windows. Each teammate consumes tokens independently. Only use for tasks where parallelism provides clear value (multi-module work, parallel reviews). For simple sequential tasks, subagents are more token-efficient.

## WARNING: Important Notes

### Token Optimization

Hitting daily limits? See the **[Token Optimization Guide](docs/token-optimization.md)** for recommended settings and workflow tips.

Quick wins:

```json
// ~/.claude/settings.json
{
  "model": "sonnet",
  "env": {
    "MAX_THINKING_TOKENS": "10000",
    "CLAUDE_AUTOCOMPACT_PCT_OVERRIDE": "50",
    "CLAUDE_CODE_SUBAGENT_MODEL": "haiku"
  }
}
```

Use `/clear` between unrelated tasks, `/compact` at logical breakpoints, and `/cost` to monitor spending.

### Customization

These configs work for my workflow. You should:
1. Start with what resonates
2. Modify for your stack
3. Remove what you don't use
4. Add your own patterns
