Re-parses the local shell history files (~/.zsh_history, ~/.bash_history) and the hook's extended log into the SQLite index. Idempotent — already-indexed commands are skipped by hash, so it is safe to call repeatedly. Run it after a burst of shell activity to make recent commands searchable. Reads only local files; writes only to ~/.terminal-history-mcp/. Takes no arguments. Returns counts of parsed / inserted / skipped entries.

Read-only. Full-text search (SQLite FTS5, stemmed, Unicode-aware) over all indexed shell commands. Supports keyword and prefix queries — e.g. docker build, git reb*. Returns the most recent matches first, each with timestamp, shell, cwd, and exit code when available. Local index only; nothing is sent anywhere. If a query returns nothing you may need reindex first.

Read-only. Lists the most recent commands that were run with a given working directory — answers "what was I doing in this project?". Requires the shell hook to have been installed (legacy entries have no cwd and won't appear). Returns newest first with timestamps and exit codes. Local index only.

Read-only. Lists recent commands that exited non-zero — a quick "what just broke?" feed. Optionally restrict to commands after a given epoch-millisecond timestamp. Requires the shell hook for exit-code capture (legacy entries have no exit code). Newest first. Local index only.

Read-only. For each command matching query, returns the commands run within a time window around it (default ±5 min) — surfacing multi-step sequences like cd → npm run build → deploy. Useful for reconstructing "how did I do X last time?". Returns up to limit chains, each a time-ordered list of command rows. Local index only.
