name	wf-develop
description	This skill should only be used when the user uses the word workflow and asks to develop or implement changes with a verification-first loop and clean handoff/pickup boundaries.

wf-develop

Purpose

Implement changes with a verification-first loop, keeping context clean between workflow steps.

prd.json (single-PRD dossier or slice PRD). plan.md may exist for higher-risk work, but it’s optional.

Prefer plan-driven work when plan.md exists, but allow PRD-driven work (especially with PRD JSON: prd.json).

Inputs

Preferred:

• Dossier path (contains one or moreprd.json ) - implement one prd.json at a time.
• Or explicit PRD JSON path (prd.json / prds/<slice_id>_<slug>/prd.json)

Optional:

• plan.md path (only when created by wf-plan)

Also:

• Target repo + branch
• Known risks/deps

Outputs

• Code changes
• Verification evidence (what ran, result, screenshots/logs when relevant)
• Update the relevant PRD JSON story passes and notes to reflect reality (prd.json or a slice prds/.../prd.json)
• Dev log artefact saved per repo conventions (summary + verification evidence + GO/NO-GO) (optional but nice)

Steps

0. (Recommended) Pickup if starting fresh thread / resuming

• Invoke pickup skill if:
  • new chat/thread, or
  • user says “resume / pick up”, or
  • repo/branch uncertain

1. Confirm work input

• If PRD JSON missing (prd.json): check if prd.md exists. If yes, run create-json-prd first (NO-GO if schema invalid). If not, ask user to create prd.md.
• If plan.md exists: use it in conjunction with prd.json to guide development.
• If no plan.md: proceed from the prd.json directly (this is normal for small work).

2. Baseline verification (before touching code)

• Run verify skill and record result.
• If verify fails before changes:
  • call out as pre-existing failure
  • ask whether to fix baseline first (recommended) or continue

3. Implement in smallest verifiable increments Loop:

• pick the next smallest slice that proves progress toward an acceptance criterion
• implement minimal change
• run targeted check then verify skill
• record evidence (what ran, result, any screenshots/logs)
• update the relevant PRD JSON:
  • set passes=true for stories fully meeting criteria
  • use notes for partials, tradeoffs, follow-ups

4. Light review loop (default) Before opening a PR / handing off:

• do a quick diff scan for naming, tests, and obvious failure modes
• rerun verify
• only escalate to wf-review when risk/size warrants it

5. Write dev log (optional) Include:

• what changed
• verification evidence
• any follow-ups / risks
• GO/NO-GO

6. Context boundary (recommended) If switching workflows next (review/release/ralph) or stopping:

• invoke handoff
• recommend new thread for the next workflow: /new then pickup with the handoff note path

7. Compound (optional but recommended) If a non-trivial issue was solved or a gotcha discovered:

• suggest invoking compound-docs skills

Verification

• Verify skill run at least once after changes.
• PRD JSON updated to reflect what passes (prd.json or slice prds/.../prd.json).

Go/No-Go

• GO if verify is green and acceptance criteria met (per the PRD JSON).
• NO-GO if verify fails or behaviour cannot be demonstrated.
