let

🧭 Find any agent asset for any agent.

Host-neutral locator + dynamic workbed for multi-host coding agents (Claude Code, Grok Build, Codex, Cursor, Merlin, corvid-agent, private runners).

let where .                         # what agent stuff is here?
let find worktrees --json           # .claude/worktrees + ~/.codex + git + …
let find skills --json              # Claude + Grok + Cursor + OpenAI + agent.3md planes
let find agents --json              # agent.3md + host agent dirs
let find memory --json              # memtrace / codex / gemini / .let (path-only)
let find sessions --json            # all hosts, path-only
let find plugins --json
let find mcp --json
let skill route "find worktrees" --json
let show skill find-worktrees --json  # progressive body load
let open ./agent.3md --json
let context --json
let doctor --json
let web                              # local, read-only Fleet dashboard

Federation over relocation: indexes host assets in place — never migrates .claude/worktrees/ into .let/.

Features

• The let standard — one closed kind set for every host; cards first, bodies on demand
• Worktrees — git seed + Claude / Codex / Cursor / project / Grok DB, deduped by realpath
• Skills — Claude, Grok, Cursor, Codex, OpenAI, let catalogs + agent.3md skill planes
• Agents — agent.3md / *.3md first-class + Claude/Codex/Cursor/Grok/Gemini/Kimi roots
• Commands — Claude + Cursor slash-commands (project + user)
• Sessions / memory — path-only federation (Claude, Grok, Codex, Cursor, Gemini, Kimi)
• Plugins / MCP / tasks — Claude plugins & tasks, Cursor plans, MCP configs across hosts
• Workflows / superskills — let-native + Grok workflow roots when present
• Show / open / route — progressive bodies + agent.3md-first skill ranking
• Hosts — Claude, Codex, Cursor, Grok, OpenAI, Gemini, Kimi Code, agent.3md, let
• Dogfood — ships agent.3md and can find + show + route itself
• JSON-first — stable envelopes for agents (--json)

Install

Via fledge (recommended for CorvidLabs projects)

fledge plugins install CorvidLabs/let
# or from a local checkout:
# fledge plugins install /path/to/let --force

fledge let doctor --json
fledge let find worktrees --json
fledge let where .

Any project that already uses fledge can install let the same way as fledge-plugin-memory / fledge-plugin-github. Agents then call fledge let … without a separate PATH setup.

Local Fleet view

let web
# or: fledge let web

Starts a local-only dashboard at http://127.0.0.1:8731. Fleet is a Let-native control room built from the federated index: it shows each local agent's status, task or latest prompt, activity, timestamps, and project context. Expanded cards may show bounded, redacted local session text from an already-indexed session file. It never provides agent controls or shell execution.

Standalone (any host: Claude, Codex, Cursor, Kimi, …)

git clone https://github.com/CorvidLabs/let
cd let
bun install
bun link          # or: ./bin/let
let doctor --json

If the shell let builtin shadows the binary, use ./bin/let or bun run src/cli.ts.
