	Description		Read-only	Idempotent	Open world
`corpusfetch_fetch_record`Fetch the full resolved experience record. Format `md` (~1,500 tokens, includes reasoning) or `py` (~300 tokens, zero-prose executable invariants).

`corpusfetch_fetch_warrant`Fetch the compact ~220-token precondition seal for a resolved record. Always call this before `corpusfetch_fetch_record`—check the seal first; if it fails, the record does not apply to your current state.

`corpusfetch_lookup_exception`Look up operational experience for an exact Python exception class (e.g., KeyError, TimeoutError, ConnectionError). Use when you encounter an unexpected runtime error and need an empirically verified boundary decision rather than a guess. Prefer `corpusfetch_search` when you have a symptom description but not an exact exception name.

`corpusfetch_lookup_symptom`Look up operational experience for a specific runtime symptom or boundary failure (e.g., UNICODE_HOMOGLYPH_OR_MOJIBAKE). Use when facing an ambiguous failure state or unbounded reasoning loop. Prefer `corpusfetch_search` if you only have a loose description.

`corpusfetch_request_experience`Request a new operational experience when `corpusfetch_search` returns no match. The corpus will generate and publish a record for your specific error or symptom within minutes. Use this instead of guessing when the problem is novel and no existing record applies.

`corpusfetch_search`Search operational records for distributed systems failures, AI agent protocol issues, MCP/A2A problems, database anomalies, concurrency bugs, and runtime errors. Use when the user's problem involves infrastructure, agent-to-agent coordination, authentication, memory management, or observability. Do not use for general programming questions—only for boundary decisions and failure modes that have been empirically recorded.
