Use when adding, renaming, or modifying this backend's FastAPI routes, dependencies, middleware, or response behavior.
Use when CI fails on a PR or main in gencc-link. Walks through reproducing make ci-local locally and root-causing without bypassing checks.
Use when changing the GenCC SQLite schema. Coordinates schema.sql, the ingest builder/aggregates, and the repository together, then rebuilds the database and updates tests and fixtures.
Use when preparing a versioned release of gencc-link. Walks through the pre-release checklist — ci-local green, CHANGELOG, version bump, valid docker config — then tagging and watching the release workflow.

Use this skill when changing the MCP tool surface (additions, renames, removals, description rewrites). GenCC-Link exposes exactly 10 tools today; the tool list is part of the public contract.
Pick the tool module. Tools are grouped by concern under
gencc_link/mcp/tools/:
discovery.py (get_server_capabilities, get_gencc_diagnostics)genes.py (search_genes, get_gene_curations)diseases.py (search_diseases, get_disease_curations)assertions.py (get_gene_disease_assertion, find_curations,
resolve_identifier)submitters.py (list_submitters)
Add the tool to the matching register_*_tools(mcp) function (create a new
group only if it genuinely does not fit an existing one).Register in the facade. If you added a new register_*_tools group, wire
it into gencc_link/mcp/facade.py create_gencc_mcp().
Update the capabilities TOOLS tuple. Edit
gencc_link/mcp/capabilities.py — the TOOLS tuple is the canonical
inventory returned by get_server_capabilities and the gencc://capabilities
resource. Order matters; keep it consistent with the README table.
Tune the description and envelope. Write the tool description for an AI
client choosing a tool: what it does, when to use it, input/output shape, and
what it does NOT do. Keep READ_ONLY_OPEN_WORLD annotations
(gencc_link/mcp/annotations.py), the run_mcp_tool envelope
(gencc_link/mcp/envelope.py), response_mode shaping
(gencc_link/services/shaping.py), and _meta.next_commands
(gencc_link/mcp/next_commands.py).
Error mapping. If the tool can raise a new exception, ensure it maps to a
typed error code (invalid_input, not_found, ambiguous_query,
data_unavailable, upstream_unavailable, rate_limited, internal_error)
in gencc_link/exceptions.py / the envelope classifier.
Tests. Add or update tests under tests/ covering the tool's behavior,
its presence in the capabilities inventory, response_mode shaping, and error
masking. Run make test (optionally -k <tool_name>).
Docs / tables. Update the tool tables in README.md,
docs/MCP_CONNECTION_GUIDE.md, and docs/usage.md. Mention the tool in
docs/architecture.md if it changes the tool grouping.
Preserved names. Existing tool names are part of the public contract.
Renaming or removing a tool requires a CHANGELOG.md entry and a migration
note.
CI. Run make ci-local.
