Specmint Core

Persistent spec management for AI coding workflows. Use this skill when the user explicitly mentions specs, forging, or structured planning: says "forge", "forge a spec", "write a spec for X", "create a spec", "plan X as a spec", "resume", "what was I working on", "spec list/status/pause/switch/activate", "implement the spec", "implement phase N", "implement all phases", "generate openapi", or exits plan mode (offer to save as a spec). Also trigger when a `.specs/` directory exists at session start. Do NOT trigger on general feature requests, coding tasks, or questions that don't mention specs

# Spec Mint Core

Turn ephemeral plans into structured, persistent specs built through deep
research and iterative interviews. Specs have phases, tasks, acceptance
criteria, a registry, resume context, a decision log, and a deviations
log. They live in `.specs/` at the project root and work with any AI
coding tool that can read markdown.

Whether `.specs/` is committed is repository policy. Respect `.gitignore`
and the user's preference for tracked vs local-only spec state.

## Critical Invariants

1. **Single-file policy**: Keep this workflow in one `SKILL.md` file.
2. **Canonical paths**:
   - Registry: `.specs/registry.md`
   - Per-spec files: `.specs/<id>/SPEC.md`, `.specs/<id>/research-*.md`,
     `.specs/<id>/interview-*.md`
3. **Authority rule**: `SPEC.md` frontmatter is authoritative. Registry is a
   denormalized index for quick lookup.
4. **Active-spec rule**: Target exactly one active spec at a time.
5. **Parser policy**: Use best-effort parsing with clear warnings and repair
   guidance instead of hard failure on malformed rows.
6. **Progress tracking is sacred**: After completing any task, immediately
   update SPEC.md (checkbox, `← current` marker, phase marker) AND
   registry.md (progress count, date). Then re-read both files to verify
   the edits landed correctly. Never move to the next task without updating
   both files. Never end a session with the registry out of sync with
   SPEC.md. This is non-negotiable — if you do nothing else, do this.

Ironloop

edouard-claude/ironloop

Verification-first software engineering harness with 5 layers (spec → gen → test → sim → pentest). Use when generating, reviewing, or planning code with AI agents, especially for Rust projects, new feature work, legacy migrations, or any task where code correctness must be guaranteed. Activates on phrases like "build a", "implement", "refactor", "review this code", "migrate from", "add tests for", or when the user describes a coding task with correctness or security requirements.
