# {{ID}} — {{title}}

Role: worker | Wave: {{n}} | Depends on: {{ids or —}} | Effort: {{S/M/L}}

## Objective
{{1–3 sentences. What must exist when done.}}

## Why
{{Which success criterion this serves.}}

## Inputs (read first)
- `.swarm/brief.md`
- `.swarm/contracts.md` §{{section}}
- `{{artifact/source}}`: {{path:start-end, URL, dataset, design file}}

## Deliverables
- `{{new or changed path/artifact}}` — {{what}}
- `{{test/evidence artifact}}` — {{what it proves}}

## Write scope (only these)
- `{{glob or exact path}}`

## Read-only
- `{{path}}`

## Contract
{{Exact signature, data shape, CLI behavior, or output format.}}

## Constraints
- {{No new dependencies, style, performance, compatibility.}}
- Context budget: read only the inputs above; if you need more than {{N}} additional files, return `blocked` instead of exploring the whole repo.
- Prerequisites are lead-owned: do not install tools, packages or system dependencies. If one is missing, return `blocked` with the exact check and error.
- Do not run the full test suite unless the card explicitly asks; run targeted checks.

## Acceptance (re-runnable)
1. `{{command or artifact path}}` → {{expected result/state}}
2. `{{citation check / metric / render at sizes}}` → {{expected result}}
3. Every criterion must have evidence a fresh verifier can reproduce.

If the quality profile is `product` and this task touches UI/interaction, also record:
- release-build p95 frame time and input latency at the target size;
- the 3–5 step user scenario;
- baseline comparison (new must not be worse).

## Report
`.swarm/reports/{{ID}}.json` per `.swarm/report.schema.json`; status `done|partial|blocked|failed`.
Keep the report to summary + evidence lines; raw logs go to `.swarm/tmp/{{ID}}/`.

## Stop conditions
- Time box: 25 minutes for S/M, 45–60 minutes for L, or 3 failed attempts at the same step.
- A load-bearing unknown, a needed file outside scope, or a broken contract → `blocked` with the exact question. Do not guess.
- If a sibling task's in-flight file causes a compile/test failure outside your scope, wait briefly and report `partial` with the exact external error; never edit that file.
