What it does
A reference implementation of a Claude on-call for a Slack alert channel. When an alert fires, Claude classifies the symptom, loads the matching playbook, checks past lessons and posts a first-pass diagnosis with each claim linked to a log line or dashboard panel. A human decides what to do. Claude watches whether metrics return to baseline and appends a conclusion to `lessons.md`. The kit holds the `oncall-setup`, `triage`, `handoff` and optional `weather` skills. Playbooks are not written from scratch: `oncall-setup` mines incident history and postmortems into drafts that you edit.
Who it is for. Infrastructure and CI teams with an alert channel and incident history who want evidence-backed first-pass triage.
Good fit when
- Night CI alerts repeat and the first pass takes the on-call an hour.
- Playbooks live in people's heads rather than in a repository.
- A shadow period is needed to check answers before going live.
- You want a handoff summary on Monday morning.
Not a fit when
- You need automatic rollback with no human decision: the kit leaves decisions to people.
- You have no Claude Team or Enterprise plan and no Claude in Slack.
- You expect a maintained product: the repository is not maintained.
Example request
@Claude run the oncall-setup skillLimitations
The repository is labelled a reference implementation: it is not maintained and accepts no contributions, with the latest commit in August 2026. Working in a channel needs Claude Tag, meaning @Claude in Slack on Team or Enterprise plans. The Claude organisation owner attaches each connection to metrics, logs, the pager and code. The kit names capabilities rather than vendors, and `STACK.md` records which tool fills each. Shadow-period answers must be checked by hand before going live.
How to disable. Disable the routines in the channel (anyone can list and remove them) and remove @Claude from the channel. Delete the kit skills and files from the repository.
FAQ
Can I try it without Slack?
Yes. The demo on a fictional history of 48 incidents runs in Claude Code and touches nothing real.
Who closes the incident?
Always a human. Claude gathers evidence, proposes a fix and checks metrics after it.
What is the shadow period?
For the first weeks Claude posts diagnoses to a review channel while humans work as before.
Which skills are in the kit?
`oncall-setup`, `triage`, `handoff` and the optional `weather`.
Is the kit tied to specific tools?
No. Skills name capabilities (metrics, logs, pager) and `STACK.md` maps them to your services.
