name: rea-tool-design description: Design or change REA investigation tools, CLI/MCP contracts, provider capabilities, and Evidence semantics.

REA tool design

Use the tool-design guide for tool boundaries, contract semantics, provider ownership, and discoverability. Inspect the current contract and nearest existing tool relevant to the analyst question; source, documentation, and live catalogs may describe different versions.

For a design request, return the proposed boundary, input/result shape, Evidence semantics, nearest alternative, and verification approach. Implement when requested, preserving the user's scope and existing authorization.

For implementation or verification, consult testing for the affected consumer and provider lanes, and contributing for generated-file ownership. Read provider/workflow guides only as the task requires.
