What it does
Add Channel Setup Guide is an agent skill from novuhq/novu. Add a new chat channel's layer-1 setup guide — the in-dashboard <ChannelSetupGuide that walks a developer through connecting the channel itself (create app/bot → save credentials → install/verify → send first message) with live connection detection — in apps/dashboard, following the existing Slack, MS Teams, and Telegram guides. Use when a new agent channel needs its numbered setup stepper, credential drawer wiring, and connectedAt polling under components/agents.
Its SKILL.md is about 1.7k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `reference.md`).
It works with Slack, Telegram and Microsoft Teams. The repository describes itself as: The open-source communication infrastructure for agents and products.
When your agent uses it
- A new agent channel needs its numbered setup stepper
- Credential drawer wiring
- ConnectedAt polling under components/agents
Example prompts
- “/add-channel-setup-guide”
Workflow steps
6 steps, taken from the first numbered list in SKILL.md.
- Resolve selectedIntegration from useFetchIntegrations() by _id === integrationId && providerId === ChatProviderIdEnum..
- Track progress: hasIntegrationCredentials(...) ‖ a local credentialsSavedLocally, plus any install/connected flags. Reset all of it in…
- Derive const base = stepOffset → compute firstIncompleteStep → deriveStepStatus(stepIndex, firstIncompleteStep) per SetupStep.
- Render the steps in SetupStepperRail, then ListeningStatus (in a pl-8 wrapper), then IntegrationCredentialsSidebar.
- ListeningStatus.onConnected → mark connected and call onStepsCompleted?.().
- Provide both an embedded return (no Overview chrome — used by the resolver) and the standalone return.
What it can do on your machine
Read from SKILL.md and the folder at commit c4d3eda. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Add Channel Setup Guide loads about 1.7k tokens when it runs. Until then it costs about 123 tokens; SKILL.md has 604 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 604 words (~1,689 tokens).
“Layer 1 = connecting the channel itself: the numbered stepper a developer follows to create the provider app/bot, save its credentials in Novu, install/verify, and send a first message — with a live "Listening… / Connected" indicator. ResolveAgentIntegrationGuide renders this…”
