Spec-dev

SkillAI & models

Plan-first development workflow — the orchestrator over the lifecycle skills: grill the idea, write one plan.md, implement it phase by phase. Use when the user wants the full disciplined loop for a feature or change: "spec-dev", "plan this out and build it", "let's think this through then implement", or disciplined, reviewed code changes end to end. For a single step alone, use that step's skill directly (grill, blueprint, mason).

Available today. Use it from your connected AI after setup.

Connect ahel once, and every AI you use reads what you have installed.

Then ask your AI: use the Spec-dev skill

What this skill tells your AI

The instructions your AI receives, as published by vaayne/agent-kit in skills/spec-dev/SKILL.md and read by ahel’s review.

An orchestrator, not an implementation: each step is its own independently invocable skill; this skill owns only the sequence, the gates, and the skip rules. The one artifact threading through is plan.md (location and format owned by blueprint).

The line

StepSkillSkip when
1. GrillgrillApproach already clear: small fixes, obvious work
2. PlanblueprintNever — the plan is the contract
3. BuildmasonNever — phase-by-phase, one commit per phase

Read each step's SKILL.md when entering it; the details live there, not here.

Optional bookends, one command away: unfamiliar territory → run scout before grilling; after landing → code-review for a real audit, teach to internalize what changed.

Gates

Pause for user approval at exactly two points:

  1. After grilling, before the plan. "Here's what I understand — should I write the plan?"
  2. After the plan, before building. "Here's the plan — should I start?"

Within implementation, don't gate every phase; mason escalates on surprises and major rework on its own.

Threading rules

  • Grilling's resolved decisions land in plan.md — grill produces no artifact of its own.
  • Mason's handoff notes and deviations stay in plan.md; when an answer changes the design, the affected plan section is updated. One file, whole story.
  • Review findings that require rework loop back to mason as a new phase, not ad-hoc patches.
