Use when adding a new messaging channel to Tel-Agent or changing an existing one — a transport under api/channels/, its official extension manifest, its settings card, tests, health and docs. Covers the file checklist, the two inbound shapes (dial-out and the public door), the credential and signature rules that are not negotiable, the declarative setup descriptor the generic card draws from, and the test shape every channel ships with.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Building a channel extension You are adding a messaging channel to Tel-Agent. A channel is a route a **customer** uses to reach a business — someone is typing on the other end. If nobody outside the business is on the other end, it is an integration, not a channel, and it is reached through the HTTP tool instead (Rule 5 in `CLAUDE.md`). Do not build it here. **Read first, in this order:** `CLAUDE.md` (the contract), `docs/SPEC.md` §B9 (secrets) and §B13 (channels), then `api/channels/discord.py` end to end. Discord is the model every channel copies: a dial-out transport with a supervisor loop, an answering policy, storage with dedup, and delivery-before-storage. For a channel that receives webhooks, also read `api/channels/meta_chat.py` and `api/routes/meta_chat_channels.py` — that is the public door, and its guards are the whole of this product's exposed surface. Write everything from the platform's **official documentation** and from the shape of the existing modules. Write it fresh. Never paste code from another product into this repository, never name another product anywhere in it, and never add a runtime …

How to install
mdr add dpro-at/tel-agent/channel-extension@sha256:75a4dafa4209f8ddThe line at the top of this page pins the label git:20260913.5db5199, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
