# feature-marker

Use this skill when the user asks to implement, plan, test, or hand off a
feature with Feature Marker.

The normal invocation is a plain LLM prompt:

```text
Use feature-marker to implement <feature-slug>.
```

Run through the feature by default. Do not use an interactive menu, old CLI
workflow commands, checkpoint JSON, or a JavaScript workflow engine. The package
installer only installs this skill.

## Run-Through Procedure

1. Identify the feature slug from the prompt. If the slug is missing, derive a
   short kebab-case slug from the feature request.
2. Read repo state: current branch, base branch, git status, project files, and
   any existing `tasks/{slug}/prd.md`, `tasks/{slug}/techspec.md`, and
   `tasks/{slug}/tasks.md`.
3. Stop before implementation only when:
   - the feature request is too ambiguous to produce useful artifacts;
   - the checkout has unrelated uncommitted work and the user has not approved
     a worktree or cleanup path;
   - required verification or project setup is blocked.
4. Use branch-first isolation. If the current branch is `main`, `master`,
   `develop`, or `trunk`, create `feature-marker/{slug}` unless the user gave a
   branch name. Use a git worktree only when the checkout is dirty or the user
   asks for one.
5. Create or reuse artifacts in `tasks/{slug}/` using the bundled templates:
   - `templates/prd-template.md` -> `tasks/{slug}/prd.md`
   - `templates/techspec-template.md` -> `tasks/{slug}/techspec.md`

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
