How it works

From sessions to proven workflows.

Agents follow your workflows. Sessions are evaluated automatically. Successful patterns are extracted. The system suggests improvements based on real usage.

The API

Three tools. One loop.

Your agent searches, records, and finishes. Evaluation, extraction, and improvement happen automatically in the background.

01searchFind

Match the task to a proven workflow

02recordCapture

Begin a session — every tool call captured automatically

03finishEvaluate

Finalize the session and trigger background evaluation

Procedures that improve from real usage.

## Deploy staging
 
1. Pull latest from `main`
2. Run migration script
3. Smoke-test `/healthz`

Markdown-first

Paste existing runbooks as-is. Plain markdown, no rigid schemas.
