# Issue Plan Slicer

## Goal

Turn a broad plan into small, ordered, independently reviewable work items that an agent or maintainer can execute safely.

## When to use

- The user asks to split a spec, roadmap item, issue, PRD, or migration into tasks.
- Work needs GitHub issue drafts, local markdown tasks, or agent-ready implementation slices.
- Dependencies, acceptance criteria, and validation need to be made explicit.

## When not to use

- The user wants immediate implementation of a narrow task.
- The plan is still too ambiguous to slice and needs product discovery first.
- The user asks for live issue creation but has not authorized tracker mutations.

## Inputs to inspect

- The source spec, issue, PRD, roadmap item, or conversation context.
- Existing `docs/agents/issue-tracker.md`, `docs/agents/triage-labels.md`, and `docs/agents/validation.md` when present.
- Existing issue templates and labels under `.github/`.
- Relevant ADRs and domain docs for boundaries and terminology.

## Workflow

1. Identify the desired outcome and non-goals.
2. Extract dependencies, risky assumptions, validation commands, and docs impact.
3. Split work into vertical slices that can be reviewed independently.
4. Mark blockers and sequencing; avoid slices that require hidden context from prior tasks.
5. Draft each issue with title, scope, acceptance criteria, validation, and out-of-scope notes.
6. If the issue tracker is unknown, produce local markdown drafts instead of tracker-specific commands.
7. Ask before creating, labeling, assigning, or closing live issues.

## Safety rules

- Do not mutate issue trackers without explicit user authorization.
- Do not create vague tasks such as "clean up code" without acceptance criteria.
- Do not hide critical dependencies in prose; make them part of the slice.
- Do not assume labels or project boards that are not documented.

## References

Use downstream `docs/agents/issue-tracker.md` and `docs/agents/triage-labels.md` as hard dependencies for tracker-specific output. If they are missing, default to local markdown issue drafts.

## Scripts

No bundled scripts.

## Output format

Return:

1. Source plan summary
2. Proposed issue order
3. Issue drafts with title, scope, acceptance criteria, validation, and dependencies
4. Tracker assumptions
5. Open questions

## Completion criteria

- Each slice can be implemented and reviewed independently.
- Dependencies and sequencing are explicit.
- Validation is attached to each slice.
- Live tracker mutation is either authorized and reported or not performed.

## Failure modes

- If the plan is too ambiguous, ask targeted questions before slicing.
- If one slice grows too large, split it by observable behavior or ownership boundary.
- If tracker docs are missing, avoid tracker-specific labels and commands.
