# Webhook-triggered: an issue acquired the label "pm:plan". Reads the parent

# issue body as a free-form goal, asks claude to decompose into 1–5 structured

# agent-issues, creates each as a child issue with label "agent:assign", and
|

# comments on the parent linking to the children.

# Parent issue title

# Constraints on the issues you produce
|
||||
|
||||
- Each issue must fit in <30 minutes of autonomous agent time on Sonnet.
|
||||
- Done criteria must be specific and mechanically verifiable (file exists,
|
||||
endpoint returns X, HTTP code, test passes). No taste calls.
|
||||
- Order issues by dependency (foundation first).
|
||||
- Use 'opus' only for tasks requiring design tradeoffs; routine
|
||||
scaffolding/CRUD/refactors are 'sonnet'.
|
||||
- Prefer fewer larger issues over many trivial ones, as long as each fits in
|
||||
30 min.
|
||||
- Avoid issues that require human judgment (\"make it look good\").
|
||||
- Do NOT call any tools — produce JSON from the prompt text alone.
|
||||
|
||||
Return only the JSON matching the schema."
