## Tool descriptions

- `run_tests` — Run Jest tests for a service. Returns pass/fail counts and structured failure details with test names and error messages. Optionally scope to a test name pattern.
- `run_typecheck` — Run TypeScript type-checking (tsc --noEmit) for a service. Returns structured errors with file, line, column, and message. Call after writing code to verify correctness before committing.
- `get_all_changes` — Get all changes in the ledger, optionally filtered by ISO timestamp.
- `get_branch_context` — Get the current git branch, HEAD SHA, and recent commits. Always call this first to anchor your context to the correct branch.
- `get_changed_files` — List files changed since a base ref (default: HEAD~1). Useful to understand scope of recent changes.
- `get_file_ledger` — Get all logged changes that touched a specific file path. Use to understand the change history of a file before modifying it.
- `get_git_diff` — Get the full unified diff between two refs (default: HEAD~1..HEAD). Returns diff text, file list, and addition/deletion counts. Use to review changes before logging them to the ledger.
- `get_session_changes` — Retrieve all changes logged in the current session. Use at session start to understand what was done previously.
- `get_track_index` — Read the index.md for a specific conductor track. Returns the live track overview and summary.
- `get_track_plan` — Read the plan.md for a specific conductor track. Returns live file content — not docs, not memory.
- `get_track_spec` — Read the spec.md for a specific conductor track. Returns the live technical specification.
- `list_tracks` — List all live conductor tracks (only tracks with a plan.md are returned). Use to understand current work in progress.
- `search_code` — Semantic search over the current branch\
- `create_track` — Create a new conductor track directory with plan.md, index.md, and metadata.json. Fails if the slug already exists.
- `log_change` — Log a code change to the persistent change ledger. Models MUST call this after modifying files. Enables cross-session coherence.
- `mine_changed_files` — Re-index files changed since last commit into MemPalace. Call after making code changes to keep the search index current.
- `update_track_index` — Overwrite index.md for an existing conductor track. Use to update the track summary, status, or linked resources.
- `update_track_plan` — Overwrite the plan.md for an existing conductor track with new content. The track must already exist. Use this to update task status, add phases, or record decisions.
- `update_track_spec` — Overwrite spec.md for an existing conductor track. Use to update technical decisions, architecture notes, or acceptance criteria.
