Onboard Messaging Channel

Use this skill to add a messaging channel end-to-end without leaking channel-specific logic into core NemoClaw code.

Intake

Gather inputs progressively. Do not ask the full intake checklist in one message. Ask one concise clarification at a time, choosing the earliest unresolved blocker:

1. If the channel name is missing, ask for the channel name.
2. If target agents are missing, ask whether the channel should support OpenClaw, Hermes, or both.
3. If upstream references are missing, ask for the official docs link and source-of-truth implementation link or path. Include Telegram as the format example: docs https://docs.openclaw.ai/channels/telegram, source https://github.com/openclaw/openclaw/tree/main/extensions/telegram.
4. After references are available, read them and the local messaging package before asking about credentials, plugin installs, reachability, or network policy.
5. Ask follow-up questions one by one only for details that remain ambiguous after source analysis.

Use this intake checklist internally while analyzing source:

• Channel name and target agents: OpenClaw, Hermes, or both. Treat unsupported agents as intentionally out of scope unless the user provides source evidence.
• Official channel documentation link and source-of-truth implementation link or path. Prefer upstream extension/runtime code over README prose when they conflict.
• Required credentials and config inputs: token environment variables, bot or app IDs, user IDs, workspace/guild/group IDs, allowlists, app secrets, webhook secrets, socket-mode/app tokens, QR pairing, callback URLs, or proxy settings.
• Plugin or package install requirements: package name, install manager, version pinning, bundled versus external status, extension ID, and whether the package must be installed during image build.
• Reachability or health evidence: endpoint or command, HTTP method, auth semantics, success response, invalid-credential response, transient-network behavior, and whether tests need a skip env var for fake credentials.
• Network reachability: every hostname used at runtime, whether it is agent-only or bridge-only, and whether the policy should be opt-in.

When asking a follow-up, include the source-derived fact that made the question necessary. Example: "The upstream extension enables a webhook secret, but I do not see whether NemoClaw should prompt for it. Should this be a required input?"

Source Analysis

Before editing, read:

• Root AGENTS.md and CONTRIBUTING.md.
• src/lib/messaging/AGENTS.md.
• The closest existing channel manifests and tests under src/lib/messaging/channels/.
• The upstream docs and source code supplied by the user.

Compare the new channel to existing patterns:

• Token plus API reachability: Telegram-style.
• Multiple credentials, socket mode, or channel-owned conflicts: Slack-style.
• Allowlists or scoped IDs: Discord-style.
• QR or pairing flow with runtime status: WeChat or WhatsApp-style.
• Agent-specific plugin install and config render: channels that require external agent extensions.

When docs and source disagree, implement from source code and note the inference in the final handoff.

Implementation Workflow

Start with the manifest. Add core code only when the manifest vocabulary cannot express a reusable concept.

1. Add src/lib/messaging/channels/<channel>/manifest.ts with auth, inputs, credentials, policyPresets, render, runtime, agentPackages, state, and hooks as needed.

2. Add channels/<channel>/template-resolver.ts only for derived render values, such as allowlist normalization, booleans, proxy URLs, or agent-specific schema differences.

3. Add hooks under channels/<channel>/hooks/ only for enrollment, external reachability checks, QR capture, conflict checks, runtime status, or health probes that cannot be static manifest data.

4. Register the manifest in channels/built-ins.ts, template resolver in channels/template-resolver.ts, and hook handlers in hooks/builtins.ts.

5. Add nemoclaw-blueprint/policies/presets/<channel>.yaml when the manifest declares a policy preset. Keep messaging-specific egress opt-in unless the project policy says otherwise.

6. Declare channel support only in src/lib/messaging/channels/<channel>/manifest.ts through supportedAgents. Do not edit agent manifests for channel availability unless a separate agent contract changed.

7. Add agent package install metadata when the channel needs an external agent plugin. For OpenClaw plugin packages, use this shape unless source evidence says otherwise:

   agentPackages: [
     {
       id: "openclawPluginPackage",
       agent: "openclaw",
       manager: "openclaw-plugin",
       spec: "npm:@openclaw/<channel>@{{openclaw.version}}",
       pin: true,
       required: true,
     },
   ],
   

8. Update docs for user-facing behavior, usually docs/manage-sandboxes/messaging-channels.mdx, command references, network policy references, and troubleshooting.

Quality Gates

• Validate the runtime config schema from upstream code. Do not copy another channel's nested config shape blindly without source evidence.
• If render enables a plugin entry, confirm the install source exists or document why it is bundled.
• Keep Hermes unsupported when only OpenClaw source support exists, and vice versa.
• Keep channel-specific conditionals out of onboard, rebuild, compiler, applier, and generated-config entrypoints unless the change is a general manifest capability.
• Persist only non-secret state. Plans may contain placeholders, availability flags, and hashes, never raw tokens.
• Mock external APIs in tests. Unit tests must not call real messaging providers.
• Use a skip env var for live reachability hooks when fake credentials are valid for local tests.
• Allow only the channel's runtime hostnames in its policy preset.

Verification

Build one targeted Vitest invocation from only the files that cover the changed behavior. Omit unaffected paths from this example, then run the resulting command once per relevant change set:

npx vitest run \
  src/lib/messaging/channels/<channel> \
  src/lib/messaging/channels/manifests.test.ts \
  src/lib/messaging/channels/metadata.test.ts \
  src/lib/messaging/compiler/manifest-compiler.test.ts \
  test/messaging-build-applier.test.ts

Add channel-specific config render, hook, policy, and channel add/remove tests when those surfaces change. Rerun the targeted command after later edits or hook autofixes that can affect the tested behavior. Run npm run docs for documentation changes. Commit and push normally so pre-commit handles cheap structural and file-local checks and pre-push runs the path-scoped type checks. Treat successful hooks as verification and do not rerun their checks manually. If pre-commit, commit-msg, or pre-push hooks were skipped or unavailable, run npm run check:diff once to reproduce those checks. Refresh origin/main first. Reserve npm test for broad runtime or test-harness changes. Reserve npm run check for repo-wide validation or coverage-baseline changes.
