Use when adding Telegram, WhatsApp, Bluesky, Slack, Discord, or custom channel support; testing channel routing, pairing, MessageChannel, runtime dependencies, or channel plugin manifests. license: MIT --- # Creating Letta Code channels Use this when adding or debugging Letta Code channel support. ## First choice - **User plugin** (`~/.letta/channels/<id>/`) for headless experiments, community plugins, and fast workflow tests. - **First-party channel** (`src/channels/<id>/`) when the channel needs bespoke Desktop UI, custom account snapshots, Slack/Discord-style auto-routing, rich protocol fields, or migration/compatibility shims. User plugins cannot shadow first-party ids: `telegram`, `slack`, and `discord` are ignored under `~/.letta/channels/`. Use ids like `telegram-test`, `whatsapp-community`, or `custom-chat`. ## Core workflow 1. Work in `~/letta/letta-code` or a worktree. 2. Read `src/channels/README.md` on branches with dynamic plugins. 3. For a user plugin, create: - `~/.letta/channels/<id>/channel.json` - `~/.letta/channels/<id>/plugin.mjs` - `~/.letta/channels/<id>/accounts.json` 4. Always implement `messageActions` if agents should reply via `MessageChannel`. 5. Start with `dmPolicy: "pairing"` for testing, or `allowlist`/`open` for known headless deployments. 6. Test all four legs: - plugin discovery/import - inbound `adapter.onMessage(msg)` to route/pairing - routed channel notification reaches the agent - outbound `MessageChannel` calls `messageActions.handleAction` → `adapter.sendMessage` 7. Run targeted tests, then `bun run typecheck`, `bun run lint`, `bun run build`. ## References Read only what is needed: - `references/user-plugins.md` — dynamic plugin manifest/account/runtime/headless flow and gotchas. - `references/first-party-channels.md` — first-party channel file cascade and safety checks. - `references/testing.md` — smoke-test checklist and commands. ## Scaffold helper Use the bundled scaffold for a minimal user plugin skeleton. Replace `<path-to-this-skill>` with this skill directory path: ```bash npx tsx <path-to-this-skill>/scripts/scaffold-user-channel-plugin.ts \ my-channel "My Channel" \ --runtime-package some-sdk@1.0.0 \ --runtime-module some-sdk ``` It creates `channel.json`, `plugin.mjs`, and `accounts.example.json`. Replace the TODO inbound/outbound implementation with the real SDK calls. ## Hard lessons - `MessageChannel` silently feels broken if `plugin.messageActions` is missing. Every plugin that should reply needs `describeMessageTool()` and `handleAction()`. - For public channels, suppress tool approval/control prompts unless there is verified operator routing. Posting approval prompts publicly leaks tool input and invites forged `approve` replies. - User plugin runtime resolution must not count parent/dev `node_modules`. Runtime modules should resolve from explicit runtime dirs only. - Headless pairing is CLI-first: `letta channels pair --channel <id> --code <code> --agent <agent-id> --conversation <conversation-id>`. - Running listeners reload `pairing.yaml` and `routing.yaml` on the next inbound miss; restart only when adapter/account config itself changed.

Install the "creating-letta-code-channels" agent skill from https://github.com/letta-ai/skills/tree/main/letta/creating-letta-code-channels. Read its SKILL.md or equivalent instructions first, install only the files needed for this workspace, and summarize any required setup before using it. Skill purpose: Builds and debugs Letta Code channels, including first-party channel adapters and dynamic user channel plugins under ~/.letta/channels. Use when adding Telegram, WhatsApp, Bluesky, Slack, Discord, or custom channel support; testing channel routing, pairing, MessageChannel, runtime dependencies, or channel plugin manifests.

Replace event_id with a unique value and outcome with success or failed. Report success only after the skill is installed and a minimal verification passes.
