+# Itô Data Atlas Agent
+
+Use this skill to design an agent that watches data sources, builds candidate
+prediction-market baskets, drafts parameter changes, and hands the result to a
+human for review.
+
+This skill describes architecture and workflow. It does not run live trading.
+
+## Guardrails
+
+- Keep all execution behind explicit human approval.
+- Require `ITO_API_KEY` only for read-only Itô data access unless a separate
+  private implementation explicitly adds execution controls.
+- Do not persist private user data unless the target repo already has a storage
+  contract and the user asks for it.
+- Do not expose private strategy logic, venue credentials, or local paths in
+  public docs.
+
+## Architecture Pattern
+
+Use four lanes:
+
+1. Research collector: public web, X, GitHub, venue docs, API metadata, and
+   Itô read endpoints when gated access exists.
+2. Basket drafter: turns sources into candidate underliers, weights, rules, and
+   questions.
+3. Risk reviewer: checks data freshness, venue limits, resolution ambiguity,
+   compliance notes, and prompt-injection exposure.
+4. Human editor: opens a chat or UI state where the user can approve, reject,
+   adjust, or ask for more research.
+
+## Workflow
+
+1. Define the user objective and excluded actions.
+2. List data sources and access requirements.
+3. Draft a basket spec with provenance for every underlier.
+4. Produce editable parameters rather than executable orders.
+5. Store an audit trail: inputs, model output, sources, and human decision.
+
+## Useful Skill Chains
+
+- `deep-research` for source collection.
+- `x-api` for current social/event signal.
+- `ito-market-intelligence` for venue and underlier context.
+- `ito-basket-compare` for user knowledge-base matching.
+- `prediction-market-risk-review` before any execution-capable integration.
+
+## Output Contract
+
+Return an implementation-ready workflow spec with:
+
+- data sources
+- access gates
+- agent roles
+- human approval points
+- storage/audit boundary
+- non-goals
