 Smriti has three agent-facing surfaces beyond the chat UI:
 
 - **CLI** (`cli/smriti_cli/main.py`) — `smriti` command, 8 subcommand groups
-- **MCP server** (`cli/smriti_cli/mcp_server.py`) — `smriti-mcp` command, 17 tools
+- **MCP server** (`cli/smriti_cli/mcp_server.py`) — `smriti-mcp` command, 21 tools
 - **Skill pack** (`cli/smriti_cli/skill_pack/`) — versioned instruction files for Claude Code and Codex
 
 Changes to any of these should include corresponding test coverage in `cli/tests/`.

 3. **An agent skill pack** — a versioned instruction file (`.claude/skills/smriti/SKILL.md` or `AGENTS.md`) that teaches the agent when to checkpoint, when not to, how to detect drift, and how to select complementary work. Install once per project.

 - **Backend capabilities** (`/health`) — the backend advertises its feature surface so agents can detect stale backends.
 - **Compact mode** (`--compact`) — artifact content omitted for token efficiency; labels and recovery instructions preserved.
 - **Project metrics** (`smriti metrics <space>`) — coordination, state quality, and branch lifecycle KPIs computed on demand from existing data.
+- **Worktrees** (`smriti worktree open/list/show/close`) — first-class git worktree primitive so multiple agents can work on the same project without sharing one checkout. Each agent gets its own working tree and staging index, eliminating the cross-agent commit pollution failure mode that motivated the feature. (V1: CRUD primitive only. Claim ↔ worktree binding and state-brief enrichment land in V2.)
