Grimoire domain decomposition skills for Claude Code
npx claudepluginhub tapania/grimoire-skillsAI-powered domain decomposition pipeline — transform a project vision into governance-checked, dependency-resolved implementation slices through structured exploration
A suite of Claude Code skills that implement the Grimoire methodology — an AI-powered domain decomposition pipeline that transforms a project vision into governance-checked, dependency-resolved implementation slices.
For the full narrative of how these skills work together, read VISION.md.
Grimoire takes a software project from "here's what I want to build" to "here's a structured, validated specification tree with delivery slices." The pipeline:
The pipeline is sequential but not mandatory — stages can be skipped. All state is stored as YAML files in a .grimoire/ directory. No server, no database — just files the agent reads and writes.
| Skill | Command | Description |
|---|---|---|
| grimoire | /grimoire | The main entry point. Describes the full pipeline, detects current stage, and routes to the right skill. |
1. VISION → 2. GOVERNANCE → 3. TAXONOMY → 4. EXPLORATION → 5. SLICING
| # | Skill | Command | What It Does | Output |
|---|---|---|---|---|
| 1a | grimoire-vision | /grimoire-vision | Structured vision declaration (domain, audience, constraints) | .grimoire/vision.md |
| 1b | grimoire-vision-playground | /grimoire-vision-playground | Creative identity exploration (taxonomy → features → prose narrative) | .grimoire/vision.md, vision-identity.yaml |
| 1c | grimoire-archaeology | /grimoire-archaeology | Bootstrap from existing codebase (reverse-engineer vision, schools, tree) | Full .grimoire/ directory |
| 2a | grimoire-governance | /grimoire-governance | Define schools with sealed/advisory wards + scoring criteria | .grimoire/schools.yaml, scoring.yaml |
| 2b | grimoire-school-tree-composer | /grimoire-school-tree-composer | Compose governance tree from archetype/overlay catalog (advanced) | .grimoire/schools.yaml |
| 3 | grimoire-taxonomy | /grimoire-taxonomy | Decompose domain into specification tree (alternatives → expand) | .grimoire/tree.yaml |
| 4a | grimoire-expand | /grimoire-expand | Expand a branch with child capabilities | Updates tree.yaml |
| 4b | grimoire-ritual | /grimoire-ritual | Full exploration loop: lenses → suggest → gate → tag → score | Ranked suggestions → tree.yaml |
| 5 | grimoire-slicing | /grimoire-slicing | Propose dependency-complete delivery slices with validation | .grimoire/slices/*.yaml |
| Skill | Command | Description |
|---|---|---|
| grimoire-gate-check | /grimoire-gate-check | Enforce sealed wards and structural gates (sole blocking authority) |
| grimoire-familiar | /grimoire-familiar | Analyze a dependency's impact on the tree |
| grimoire-pathfinder | /grimoire-pathfinder | Critical path and bottleneck analysis |
| grimoire-refactor | /grimoire-refactor | Tree structural surgery (merge, split, reparent, prune) |
| grimoire-retrospective | /grimoire-retrospective | Post-implementation calibration against actuals |
# Add the marketplace
/plugin marketplace add tapania/grimoire-skills
# Install the plugin
/plugin install grimoire-skills@tapania-grimoire-skills
Or use the interactive plugin manager:
/plugin
Navigate to Marketplaces tab, add tapania/grimoire-skills, and install from the Discover tab.
Requirements: Claude Code version 1.0.33 or later (claude --version to check)
git clone https://github.com/tapania/grimoire-skills.git
cp -r grimoire-skills/skills/ your-project/.claude/skills/
git clone https://github.com/tapania/grimoire-skills.git
cp -r grimoire-skills/skills/* ~/.claude/skills/
For a new project, run skills sequentially:
/grimoire-vision → /grimoire-governance → /grimoire-taxonomy → /grimoire-expand → /grimoire-ritual → /grimoire-slicing
Or just run /grimoire and it will guide you through the pipeline based on current state.
