Return the versioned SIFS CLI/MCP contract for agents.

Search a codebase with a natural-language, code, or exact-symbol query.

Use hybrid by default, bm25 for exact identifiers and literals, and semantic for conceptual behavior. Optional language and filter_paths filters narrow the index when the agent already knows where to look. Use source for local paths or Git URLs and limit for result bounds. Results include formatted text for context injection and structured fields.

Find code chunks semantically similar to a known file and one-based line.

Use this after search returns a promising location. Pass the file path exactly as it appears in a result and a line inside that chunk. Results include formatted text for context injection and structured fields.

Inspect the active index for a local path or Git repository.

Use this to discover the selected source, whether it is cached in memory, how many files and chunks are indexed, which languages are covered, and which tools are available before searching.

Rebuild the selected index and replace the in-memory MCP cache. Use after files change in a long-lived session.

Remove the selected source from the in-memory MCP cache. The next search or status call rebuilds or reloads it.

List repository-relative file paths included in the selected index.

Read the indexed chunk containing a repository-relative file path and one-based line.

List saved SIFS profiles.

Show one saved SIFS profile.

Record local feedback about SIFS agent friction.

List local SIFS feedback entries.

Render a SIFS agent skill, instruction snippet, or MCP guidance artifact without writing files.

Inspect SIFS agent artifact readiness. This is read-only and reports unknown for current-session visibility when it cannot be proven.

Create the SIFS Claude agent file in the shared workspace.
