Version check ([version_check])
Part of the config reference.
[version_check] controls the best-effort check for a newer published rag-rat on crates.io,
surfaced to agents/operators in the SessionStart digest and the index_status MCP tool’s version
field (current vs latest + the cargo install rag-rat --force update command):
[version_check]
enabled = true # opted in by default; false makes zero network calls
The check is cached (refreshed at most once a day, out of band by the long-lived rag-rat mcp
server) and fail-open — offline, a non-200, or a parse miss simply yields no version info, never
an error, and never blocks session start (reads only the cache; rag-rat version-check refreshes
it synchronously on demand). The cache lives at <index-dir>/version-check.json. Set
enabled = false to disable the feature entirely (no crates.io requests).
