Add three read-only capability-discovery tools so new LLM sessions can
learn the workflow rules and available project skills from the MCP
server instead of long pasted operator prompts:
- mcp_get_control_plane_guide: active profile, authenticated identity
(fail-soft; unresolved identity returns STOP instructions),
allowed/forbidden operations, profile-aware guidance (author profiles
are told review/approve/merge is forbidden; reviewer profiles are told
review/merge requires eligibility checks and a pinned head SHA; mixed
profiles get a misconfiguration warning), and the standing rules: hard
stops, fail-closed behavior, head-SHA pinning, merge confirmation,
redaction, author/reviewer/merger separation, profile switching, and
identity verification.
- mcp_list_project_skills: registry of ten project workflows (issue
authoring, PR creation, PR review, PR merge, issue comments, profile
switching, redaction/security review, Jenkins read-only, GlitchTip
read-only, release/operator) with description, when-to-use, required
operations, status, and per-profile availability. Unimplemented
services are listed as designed-not-implemented rather than omitted.
- mcp_get_skill_guide: step-by-step guide per skill; unknown names fail
closed with the list of valid names.
All three are read-only and change no existing gate or permission.
Normal output contains no endpoint URLs or keychain IDs; the guide
includes the server host only under GITEA_MCP_REVEAL_ENDPOINTS=1.
Tests (tests/test_operator_guide.py, 17 new): profile-aware guidance
for author/reviewer, unresolved-identity STOP, read-only behavior,
redaction defaults and reveal opt-in, rules coverage, registry
completeness and profile awareness, unimplemented-service marking,
fail-closed unknown skill names.
Docs: llm-workflow-runbooks.md now tells new sessions to call the guide
tools first.
