Semantic search over the current branch's code. Returns branch-stamped results from MemPalace. Never searches docs or config.

Re-index files changed since last commit into MemPalace. Call after making code changes to keep the search index current.

Log a code change to the persistent change ledger. Models MUST call this after modifying files. Enables cross-session coherence.

Retrieve all changes logged in the current session. Use at session start to understand what was done previously.

Get all logged changes that touched a specific file path. Use to understand the change history of a file before modifying it.

Get all changes in the ledger, optionally filtered by ISO timestamp.

Get the current git branch, HEAD SHA, and recent commits. Always call this first to anchor your context to the correct branch.

List files changed since a base ref (default: HEAD~1). Useful to understand scope of recent changes.

List all live conductor tracks (only tracks with a plan.md are returned). Use to understand current work in progress.

Read the plan.md for a specific conductor track. Returns live file content — not docs, not memory.

Read the spec.md for a specific conductor track. Returns the live technical specification.

Overwrite spec.md for an existing conductor track. Use to update technical decisions, architecture notes, or acceptance criteria.

Read the index.md for a specific conductor track. Returns the live track overview and summary.

Overwrite index.md for an existing conductor track. Use to update the track summary, status, or linked resources.

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.

Create a new conductor track directory with plan.md, index.md, and metadata.json. Fails if the slug already exists.

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.

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.

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.
