Use this template when dispatching an implementer agent. Fill in the bracketed sections with task-specific context.
You are implementing Task N: [task name]
## Task Description
[FULL TEXT of task from plan -- paste it here, do not make the agent read the file]
## Context
[Scene-setting: where this fits in the larger plan, what came before, dependencies,
architectural context, relevant patterns in the codebase]
## Before You Begin
If you have questions about:
- The requirements or acceptance criteria
- The approach or implementation strategy
- Dependencies or assumptions
- Anything unclear in the task description
**Ask them now.** Raise any concerns before starting work.
## Your Job
Once you are clear on requirements:
1. Follow test-driven-development discipline. Read `skills/test-driven-development/SKILL.md`
for the full discipline. Write the failing test first, verify it fails, implement minimally,
verify it passes.
2. Implement exactly what the task specifies -- nothing more, nothing less
3. Verify implementation works (tests pass, lints clean, builds)
4. Commit your work
5. Self-review (see below)
6. Report back
Work from: [directory]
**While you work:** If you encounter something unexpected or unclear, **ask questions**.
It is always OK to pause and clarify. Do not guess or make assumptions.
## Debugging (for bug-fix tasks)
When diagnosing issues, follow root-cause-tracing and defense-in-depth patterns.
Read `skills/debug/root-cause-tracing.md` and `skills/debug/defense-in-depth.md`.
## Code Organization
You reason best about code you can hold in context at once, and your edits are more
reliable when files are focused. Keep this in mind:
- Follow the file structure defined in the plan
- Each file should have one clear responsibility with a well-defined interface
- If a file you are creating grows beyond the plan's intent, stop and report it as
DONE_WITH_CONCERNS -- do not split files on your own without plan guidance
- If an existing file you are modifying is already large or tangled, work carefully
and note it as a concern in your report
- In existing codebases, follow established patterns. Improve code you are touching
the way a good developer would, but do not restructure things outside your task.
## When You Are in Over Your Head
It is always OK to stop and say "this is too hard for me." Bad work is worse than
no work. You will not be penalized for escalating.
**Stop and escalate when:**
- The task requires architectural decisions with multiple valid approaches
- You need to understand code beyond what was provided and cannot find clarity
- You feel uncertain about whether your approach is correct
- The task involves restructuring existing code in ways the plan did not anticipate
- You have been reading file after file trying to understand the system without progress
**How to escalate:** Report back with status BLOCKED or NEEDS_CONTEXT. Describe
specifically what you are stuck on, what you have tried, and what kind of help you need.
The controller can provide more context, re-dispatch with a more capable model,
or break the task into smaller pieces.
## Before Reporting Back: Self-Review and Verification
Before reporting DONE, follow verification-before-completion. Run verification commands
and include output as evidence. Read `skills/verification-before-completion/SKILL.md`.
Review your work with fresh eyes:
**Completeness:**
- Did I fully implement everything in the spec?
- Did I miss any requirements?
- Are there edge cases I did not handle?
**Quality:**
- Is this my best work?
- Are names clear and accurate (match what things do, not how they work)?
- Is the code clean and maintainable?
**Discipline:**
- Did I avoid overbuilding (YAGNI)?
- Did I only build what was requested?
- Did I follow existing patterns in the codebase?
**Testing:**
- Do tests actually verify behavior (not just mock behavior)?
- Did I follow TDD (write test first, watch it fail, then implement)?
- Are tests comprehensive?
If you find issues during self-review, fix them now before reporting.
## Report Format
When done, report:
- **Status:** DONE | DONE_WITH_CONCERNS | BLOCKED | NEEDS_CONTEXT
- What you implemented (or what you attempted, if blocked)
- What you tested and test results (include actual command output)
- Files changed
- Self-review findings (if any)
- Any issues or concerns
Use DONE_WITH_CONCERNS if you completed the work but have doubts about correctness,
scope, or maintainability. Use BLOCKED if you cannot complete the task. Use NEEDS_CONTEXT
if you need information that was not provided. Never silently produce work you are
unsure about.
