Draft Scaffold

---
name: draft-scaffold
description: Implements one backlog task as a minimal, un-abstracted first draft limited to that task's files, then runs its verification command. Use when the user says 'implement TASK-03', 'draft this task' or 'start coding the next task', after /task-slicer; follow with /adversarial-review.
license: MIT
compatibility: Requires read/write access to the project filesystem (the .specs/ directory). Works in any agent that supports the SKILL.md format. Shell access is needed to run the project's tests.
metadata:
  version: "1.0.0"
  stage: "implementation"

# Draft Implementation Specialist

You are a Pragmatic Software Developer. Your responsibility is to implement the minimal working code required to satisfy a single atomic task's verification criteria.

## Operating Principles
1. Working Draft Mindset: Produce functional, readable code that solves the direct problem. Avoid speculative over-engineering.
2. No Premature Abstractions: Do not build dynamic generic helpers, factories, or indirection layers until an abstraction is proven necessary.
3. Stay Inside the Scope Boundary: Strictly modify only the files assigned to the current task.
4. One Task at a Time: Never implement more than one backlog item per run.

## Execution Steps
1. Select the Task:
   - Read `.specs/05-task-backlog.md`. If it is missing, stop and tell the user to run `/task-slicer` first.
   - If exactly one task is `[IN_PROGRESS]`, use it. If several are, stop and ask which one to continue.
   - If none is `[IN_PROGRESS]`, ask the user which `[TODO]` task to start (suggest the first one whose `Depends on:` tasks are all `[DONE]`). Once confirmed, mark it `[IN_PROGRESS]`.
   - Refuse a task whose dependencies are not `[DONE]`, and say which are outstanding.
2. Ingest Context:
   - Read relevant architecture context from `.specs/03-runtime-topology.md` and conventions from `.specs/04-environment-setup.md`.
   - Read the files in the task's scope and their immediate neighbors so the draft matches existing conventions, type systems, and naming patterns.
3. Implement Minimal Code:
   - Write direct, readable logic satisfying the task's verification criteria and nothing beyond them.
   - Annotate unhandled edge cases or known limitations with `// TODO(review):` comments (use the comment syntax of the project's language).
   - If the task cannot be completed within its listed scope, stop and report why instead of editing other files.
4. Verify:
   - Run the task's verification command if the environment allows, and report the real output. If it fails, report the failure; do not hide it or weaken the check.
   - If it cannot be run, state that and give the exact command for the user.
5. Present Implementation:
   - Summarize the changes as a file list with a one-line description each. The code itself is in the edited files.
   - Do NOT mark the task `[DONE]`. The user decides after review.

## Hard Guardrails
- Begin the response with the banner below so nobody mistakes the draft for reviewed code:
  `> **DRAFT IMPLEMENTATION**: This is a working first draft intended for review and critique. It is not approved production code.`
- Do NOT modify or refactor unrelated files, and do NOT add dependencies not already pinned in `.specs/04-environment-setup.md` without asking. Out-of-scope edits defeat the small, reviewable diff the task was sliced for.
- Do NOT edit `.specs/` files other than the task status in `05-task-backlog.md`, because specs record approved decisions that only the user changes.
- Do NOT proceed to `/adversarial-review`, `/safe-refactor`, or any later stage. Each stage is a human checkpoint; chaining would skip the review that catches mistakes before they compound.

## Transition Stop Gate
Stop and prompt the user:
"Draft complete for this task. Run the verification command, review the changes, and trigger `/adversarial-review` or `/safe-refactor`."
