Read from the source code; the running server may differ. Descriptions are the server’s own words; hidden characters are shown as [U+…].

• analyze_api_surface_mutation

  Compares a file against its HEAD version and classifies the change as `breaking_api_change` (exported function signature changed, parameter removed/added, interface field removed) or `internal_refactor` (only implementation body changed). Use to answer: is this PR a breaking change or a safe refactor?

• detect_architectural_cycles

  Detects circular import dependencies — A imports B which imports C which imports A. Cycles cause unpredictable module initialization order and indicate tight coupling. Use to answer: are there circular dependencies I need to break before refactoring?

• differentiate_type_impact

  Classifies each changed file as type-only or runtime, then splits affected tests into "must run" vs "skippable". A test is skippable when the changed file contains only TypeScript type declarations (interfaces/type aliases) or the test imports it via `import type`. Use to answer: which tests can I skip after a type-only refactor?

• explain_impact

  Finds the exact import chain that connects a changed source file to a test file. Use to answer: why does changing file X cause test Y to be affected? Returns the step-by-step import path from the test to the changed file.

• generate_skeleton_view

  Generates a token-optimized representation of a source file by stripping function and method bodies, keeping only JSDocs and declarations with line numbers.

• generate_test_command

  Outputs the optimal test execution command for Jest, Vitest, or Playwright based on changed files.

• get_affected_tests

  Given a list of changed source files, returns which test files are affected — directly or transitively through the import graph. Use to answer: which tests should I run after this code change?

• get_affected_tests_by_branch

  Runs `git diff --name-only <base_branch>...HEAD` internally and returns affected test files. Use instead of get_affected_tests when you want the server to handle the git diff automatically.

• get_coverage_gaps

  Finds source files that are not reachable from any test file through the import graph — i.e. completely untested code. Use to answer: which parts of the codebase have zero test coverage?

• get_dependency_graph

  Returns the direct import graph for a specific file: what it imports, and what imports it. Use to answer: what depends on this file? What does this file depend on?

• get_rename_aware_diff

  Like get_affected_tests_by_branch, but correctly handles renamed and moved files. Uses --find-renames to detect file moves and --ignore-all-space to skip whitespace-only changes. Use instead of get_affected_tests_by_branch when the branch contains refactors or file moves.

• get_symbol_dependency_graph

  Retrieves a bidirectional or directed dependency graph mapped to individual declarations, functions, and variables.

• get_test_summary

  Returns a bird's-eye view of the project's test structure: coverage rate, most-imported source files (highest risk to change), and tests with the deepest import chains. Use to answer: what is the overall test health of this project?

• identify_unreachable_modules

  Finds source files that are never imported by any other file — dead code candidates safe to delete. Automatically excludes known entry points (index.ts, main.ts, pages/, routes/, app/, api/, bin/). Use to answer: which files in this codebase are orphaned and can be safely removed?

• refresh_project

  Clears the cached AST for a project root, forcing a full re-parse on the next call. Use after switching branches, running git pull, or adding/removing files.
