Tell the server which files changed, so that the index and search read the new content.

A server that watches the project finds edits without this call.

Args: files: Changed file paths, relative or absolute.

List the files that a change to the given files can affect: the files that import them, directly or through other files.

Find where a symbol is defined and each place that references it: calls, imports and attribute accesses.

Args: file_path: When names collide, select the definition in this repository-relative file. line: Select the definition by its start line. cursor: Continue a paged result. page_size: References per page, 1 to 100 (default 20).

Follow the calls of a function or method.

Args: symbol: Function or method name, qualified or bare. direction: "callees" (what it calls) or "callers" (what calls it). depth: Maximum number of hops (default 1).

Show what a file imports and which files import it.

List the functions, classes and methods that a file defines.

Find symbol definitions by name, best match first: exact, prefix, substring, case-insensitive and camelCase or snake_case parts.

Args: name: A name or part of one, for example "parse_file" or "Router". kind: Optional filter: function, class, method, variable, constant, interface or type. task_hint: Optional task text that orders equal matches.

Get a symbol in one call: definition, source excerpt, references, imports and candidate tests.

A name is enough. For an ambiguous name, the result lists choices: give the repository-relative file_path and the definition start line to select one. Add task_hint to order the excerpts and tests for your task. For a long definition, follow next_source or set source_start_line. Keep each context_ranges group with its excerpt. Missing relationships do not prove absence.

List one directory level: subdirectories with file counts and languages, and files with importance and top symbols.

Args: path: Directory relative to the project root ("" for the root). importance_threshold: Minimum file importance, 0.0 to 1.0. task_hint: Optional task text that orders the files.

Summarize the project: purpose, size, entry points, architecture, layout, dependency layers, tech stack, tests and build.

Find where a behavior is implemented in an unfamiliar repository.

With task_hint, the result has the code that matches the task, a project summary, a map and the conventions.

Args: task_hint: What you want to find or change. indexing_depth: "auto" (default), "eager", "lazy" or "minimal".

Show the files around the given files: what they import and what imports them, with their top symbols.

Args: files: Center file paths. depth: Number of hops, 1 or 2 (default 1). task_hint: Optional task text that orders the files.

Review changed files for security issues, rule violations and convention problems in one report.

Args: files: Files to review (default: the files that git reports as changed). mode: "quick" (security only) or "full".

Suggest candidate tests using imports and syntax; optionally focus on a symbol and task.

Search the code by meaning with a natural-language query. Returns files, functions and classes, best first.

Args: query: For example "authentication middleware". file_filter: Optional glob, for example "*.py". branch: Remote service only. Local search reads the working tree. mode: "auto" (default), "keyword", or "vector" (waits for embeddings).

Search file contents with a regular expression. A trigram index selects the candidate files first.

Args: pattern: A regular expression, for example "def process_.*event". path: Optional subdirectory relative to the project root. selectivity_threshold: Skip the index when more than this share of files can match (default 0.10). explain: Add search diagnostics to the output.

Available tools, profiles, workspace selection, and optional enhancements.
