lsp-architecture

Generate a structural architecture overview of a codebase: languages, package map, entry points, dependency graph, and hotspots. One call for the big picture.

lsp-concurrency-audit

Concurrency safety audit for a type or file. Maps all fields, traces which are accessed from concurrent contexts (goroutines, threads, async tasks), and flags fields that lack synchronization. Produces a field-level safety report. Language-agnostic across 4 concurrency families.

lsp-cross-repo

Cross-repository analysis — find all callers of a library symbol in one or more consumer repos. Use when refactoring a shared library and need to understand how consumers use it.

lsp-dead-code

Enumerate exported symbols in a file and surface those with zero references across the workspace. Use when auditing for dead code, cleaning up APIs, or checking which exports are safe to remove.

lsp-docs

Three-tier documentation lookup for any symbol — hover → offline toolchain doc → source definition. Use when hover text is absent, insufficient, or the symbol is in an unindexed dependency.

lsp-edit-export

Safe workflow for editing exported symbols or public APIs. Use when changing a function signature, modifying a public type, or altering any symbol used outside its own package — finds all callers first so nothing breaks silently.

lsp-edit-symbol

Edit a named symbol without knowing its file or position. Use when you want to change a function, type, or variable by name and don't have exact coordinates. Resolves the symbol to its definition, retrieves its full range, and applies the edit.

lsp-explore

"Tell me about this symbol": hover + implementations + call hierarchy + references in one pass — for navigating unfamiliar code.

lsp-extract-function

Extract a selected code block into a named function. Primary path uses the language server's extract-function code action; falls back to manual extraction when no code action is available. Validates captured variables, scope shadowing, and compilation after extraction.

lsp-fix-all

Apply available quick-fix code actions for all current diagnostics in a file, one at a time with re-collection between each fix. Use to bulk-resolve errors and warnings the language server can fix automatically.

lsp-format-code

Format a file or selection using the language server's formatter. Use before committing to apply consistent style, or after generating code to clean up indentation and spacing. Supports full-file and range-based formatting.

lsp-generate

Trigger language server code generation — implement interface stubs, generate test skeletons, add missing methods, generate mock types. Uses suggest_fixes to surface generator options and execute_command to run them.

lsp-impact

Blast-radius analysis for a symbol or file — shows all callers, type supertypes/subtypes, and reference count before you change it. Use when refactoring, deleting, or changing the signature of any function, type, or method. Also accepts a file path to surface all exported-symbol impact in one shot.

lsp-implement

Find all concrete implementations of an interface or abstract type. Use when you need to know what types satisfy an interface, or what subtypes exist before changing a base type.

lsp-inspect

Full code quality audit for a file, package, or directory. Supports batch mode (directory walk with --top ranking), comparison mode (--diff for branch-only issues), severity calibration by blast radius, fix suggestions, and confidence tiers. Applies a check taxonomy (dead symbols, silent failures, error wrapping, coverage gaps, test coverage, doc drift, unrecovered panics, context propagation, concurrency safety) using LSP-first strategies. Concurrency checks cover 25 languages across 4 families (goroutine, thread, async, actor). Produces a severity-tiered findings report. Language-agnostic.

lsp-local-symbols

Fast file-scoped symbol analysis — find all usages of a symbol within the current file, list all symbols defined in the file, and get type info at a position. Use when you need local-scope analysis without a workspace-wide search.

lsp-onboard

First-session project onboarding. Explores the project structure, detects build system, test runner, entry points, and key architecture patterns. Produces a structured project profile the agent can reference throughout the session.

lsp-refactor

Phase 5: find and run affected tests

lsp-rename

Capture pre-rename diagnostics, execute rename, apply, verify

lsp-safe-edit

Collect post-edit diagnostics, surface code actions, format

lsp-simulate

Speculative code editing session — simulate changes in memory before touching disk. Use when planning edits that might break things, exploring refactors across multiple files, or verifying an edit is safe before applying.

lsp-test-correlation

Find and run the tests that cover a source file. Use after editing a file to discover exactly which test files and test functions need to run — without running the entire test suite.

lsp-understand

Deep-dive exploration of unfamiliar code — given a symbol or file, builds a complete Code Map showing type info, implementations, call hierarchy (2-level depth limit), all references, and source. Broader than lsp-explore: accepts files, synthesizes multi-symbol relationships, and produces a navigable dependency map.

lsp-verify

Post-verification: apply code action fixes and format
