Agent root-causes a cache regression and files a fix ticket
When a sustained cache hit-rate drop is confirmed, an agent investigates the offending GitLab config change, drafts a root-cause analysis with a concrete fix.

- LogicAgent reasons root cause and drafts fix
- ActionFile RCA ticket assigned to owning teamLinear
- OutputPost RCA summary to SlackSlack
What it does
On a confirmed cache regression, an agent pulls the suspect config change, the cache stats before and after, and the affected jobs, then reasons about the root cause: an over-broad cache key, a missing fallback key, a reordered install step, or a base-image bump. It drafts a root-cause analysis with a proposed fix, files a Linear ticket assigned to the owning team, and posts a summary to Slack.
When to use it
Use it when you want more than an alert. The deterministic detectors say what broke; this agent explains why and turns it into actionable, owned work so the fix actually gets scheduled rather than rediscovered each sprint.
How it works
- 1A webhook fires when a confirmed regression event is emitted.
- 2The agent reads the regression context and cache metrics from Postgres.
- 3It fetches the suspect commit and surrounding CI config from GitLab.
- 4It reasons through likely causes and drafts an RCA with a concrete fix.
- 5It files a Linear ticket with the analysis and assigns the owning team.
- 6It posts a Slack summary linking the ticket and the offending change.
