Reverse prompt

Use this skill when

• The user explicitly asks to improve, rewrite, sharpen, or reverse-prompt a request.
• The user says "before you start" or similar and wants a repo-grounded brief before planning or implementation.
• The current ask is under-specified enough that a tighter brief would materially improve speed, correctness, or completion quality.
• The user wants prompt improvement as a precursor to research, planning, or implementation.
• The user wants a definition of done, success criteria, or failure checks expressed as a sharper execution brief before work starts.
• The best next step is to turn a rough ask into a reusable execution brief with grounded file, scope, and validation details.

Do not use this skill when

• The request is already specific enough to execute directly without a prompt rewrite pass.
• The user wants direct implementation right now and has not asked for any prompt, brief, or execution-contract rewrite first.
• The task is generic prompt-writing advice with no repository grounding or execution context.
• The behavior should be an always-on instruction or extension policy instead of a situational workflow.

Inputs to gather

Required before rewriting

• The user's actual objective.
• Scope boundaries or exclusions.
• Constraints on files, behavior, tools, or rollout.
• The expected deliverable.
• Any stated approval, review, or completion rule.

Helpful if present

• Exact files or directories worth naming in the rewritten brief.
• Existing scripts, tests, or review gates that should shape the brief.
• The most likely next phase after rewriting: research, plan, or implement.
• Nearby repo conventions or instructions that should be reflected explicitly.

Only surface as blockers when needed

• Missing target surfaces that cannot be safely inferred.
• Conflicting goals or constraints that materially change the work.
• Missing validation expectations for work that clearly needs a completion check.

First move

1. Identify what structure is missing from the user's current ask.
2. Ground the rewrite in repository-local specifics that can be stated safely.
3. Decide whether this is rewrite-and-return or rewrite-and-proceed before doing deeper work.

Workflow

1. Extract the user's intent, scope, constraints, deliverable, and completion signal.
2. Use references/decision-rules.md to choose rewrite-and-return, rewrite-and-proceed, or blocked.
3. Fill the brief shape from references/brief-template.md, adding exact file or directory mentions when they are known.
4. If the user wants explicit success criteria or a reusable definition of done, switch to the contract-shaped variant in references/contract-shaped-brief.md.
5. Keep assumptions and blockers explicit instead of hiding them inside the rewritten brief.
6. If the task is rewrite-and-return, deliver the improved brief, note assumptions or blockers, and recommend the next phase.
7. If the task is rewrite-and-proceed, use the improved brief internally and continue into the appropriate next phase immediately.
8. If a blocking ambiguity remains after rewriting, stop at the rewritten brief plus blocker instead of forcing execution.

Guardrails

• Must sharpen the request faithfully instead of inventing new requirements.
• Must keep the rewrite grounded in the user's ask and repository context.
• Must not silently start work when prompt-help intent is explicit and execution intent is absent.
• Must not invent new requirements just to make the brief look more formal.
• Should use the contract-shaped brief variant when the user explicitly wants success criteria, constraints, and checks in the rewritten prompt.
• Should keep the rewritten brief concise enough that it can be reused directly in a follow-up prompt.
• Should prefer exact file or directory mentions when they can be grounded safely.

Validation

• Re-read the rewritten brief and confirm the next action is obvious within a few seconds.
• Confirm the dual-mode behavior in SKILL.md matches references/decision-rules.md.
• Confirm the brief shape still covers goal, constraints, deliverables, approval rule, exact files when known, assumptions, validation or checks, and recommended next phase.
• Sanity-check against the examples in assets/examples.md.

Examples

• Reverse-prompt this request for this repo, then execute it: fix the failing handler tests under @pkg/api.
• Improve this prompt only: audit @skills/README.md and tell me the best next prompt to use.
• Before you start, sharpen my prompt into a repo-grounded brief and then move into a planning pass: add a new skill under @skills/.

Reference files

• Read references/brief-template.md when you need the canonical brief shape.
• Read references/contract-shaped-brief.md when the user wants success criteria, definition-of-done language, or a stricter execution brief.
• Read references/decision-rules.md when the choice between return-only, proceed, or blocker is unclear.
• Read assets/examples.md when you want before/after examples or a quick sanity check for mode selection.
