list_repos

Lists the indexed repositories, one page at a time.limit?: integeroffset?: integer

query

Hybrid keyword and semantic search over the graph, with results grouped by execution flow.search_query: stringtask_context?: stringgoal?: stringlimit?: numbermax_symbols?: numberinclude_content?: booleanmaxTokens?: integerrepo?: stringservice?: string

context

Everything known about one symbol: callers, callees, references and the flows it takes part in.name?: stringuid?: stringfile_path?: stringfile?: stringkind?: stringinclude_content?: booleanmaxTokens?: integerrepo?: stringservice?: string

impact

Works out what a change to a function, class or file would affect, grouped by depth with a confidence for each hit.target?: stringdirection: stringtarget_uid?: stringmode?: stringline?: integerfile_path?: stringkind?: stringmaxDepth?: numberrelationTypes?: arrayincludeTests?: booleanminConfidence?: numberrepo?: stringlimit?: integeroffset?: integersummaryOnly?: booleanmaxTokens?: integertimeoutMs?: number

detect_changes

Maps the lines changed in git (working tree or against a base ref) to the symbols and flows they touch.scope?: stringbase_ref?: stringworktree?: stringrepo?: string

check

Runs structural checks on the indexed graph, such as import cycles.cycles?: booleanrepo?: string

rename deletes

Renames a symbol across files using graph and text matches; only previews unless dry_run is false, then edits files in place.new_name: stringsymbol_name?: stringsymbol_uid?: stringfile_path?: stringdry_run?: booleanrepo?: string
