Our review
Integrates an existing Claude skill into a project's development guidelines, storing adapted content and examples under .trellis/spec.
Strengths
- Provides a structured, repeatable method for adapting skills into project docs.
- Separates guidelines from code, preventing direct codebase changes.
- Uses .template suffixes to avoid IDE errors on example files.
- Generates a detailed integration report for review and sign-off.
Limitations
- Requires a .trellis project structure and existing target spec files.
- Depends on the chosen skill being available via openskills.
- Only updates documentation, so direct skill execution still requires manual intervention.
When your team wants to codify a reusable Claude skill's conventions and best practices into the project's development guidelines.
When you need to apply the skill directly to generate or modify application code rather than document its usage.
Security analysis
CautionThe skill is a meta-skill that guides integration of other skills by reading them and installing dependencies. It uses bash commands and network (npm install), which is legitimate but could lead to execution of third-party code if a malicious skill is integrated. No destructive or exfiltrating commands are present.
- •Instructs execution of shell commands (openskills read, npm install) without declaring allowed tools, which could be used to run arbitrary package installation or command read.
- •Relies on an external CLI ('openskills') that may not be present or verified.
Examples
/trellis:integrate-skill frontend-design/trellis:integrate-skill mcp-builder/trellis:integrate-skill doc-coauthoringIntegrate Claude Skill into Project Guidelines
Adapt and integrate a Claude global skill into your project's development guidelines (not directly into project code).
Usage
/trellis:integrate-skill <skill-name>
Examples:
/trellis:integrate-skill frontend-design
/trellis:integrate-skill mcp-builder
Core Principle
[!] Important: The goal of skill integration is to update development guidelines, not to generate project code directly.
- Guidelines content -> Write to
.trellis/spec/{target}/doc.md- Code examples -> Place in
.trellis/spec/{target}/examples/skills/<skill-name>/- Example files -> Use
.templatesuffix (e.g.,component.tsx.template) to avoid IDE errorsWhere
{target}isfrontendorbackend, determined by skill type.
Execution Steps
1. Read Skill Content
openskills read <skill-name>
If the skill doesn't exist, prompt user to check available skills:
# Available skills are listed in AGENTS.md under <available_skills>
2. Determine Integration Target
Based on skill type, determine which guidelines to update:
| Skill Category | Integration Target |
|----------------|-------------------|
| UI/Frontend (frontend-design, web-artifacts-builder) | .trellis/spec/frontend/ |
| Backend/API (mcp-builder) | .trellis/spec/backend/ |
| Documentation (doc-coauthoring, docx, pdf) | .trellis/ or create dedicated guidelines |
| Testing (webapp-testing) | .trellis/spec/frontend/ (E2E) |
3. Analyze Skill Content
Extract from the skill:
- Core concepts: How the skill works and key concepts
- Best practices: Recommended approaches
- Code patterns: Reusable code templates
- Caveats: Common issues and solutions
4. Execute Integration
4.1 Update Guidelines Document
Add a new section to the corresponding doc.md:
@@@section:skill-<skill-name>
## # <Skill Name> Integration Guide
### Overview
[Core functionality and use cases of the skill]
### Project Adaptation
[How to use this skill in the current project]
### Usage Steps
1. [Step 1]
2. [Step 2]
### Caveats
- [Project-specific constraints]
- [Differences from default behavior]
### Reference Examples
See `examples/skills/<skill-name>/`
@@@/section:skill-<skill-name>
4.2 Create Examples Directory (if code examples exist)
# Directory structure ({target} = frontend or backend)
.trellis/spec/{target}/
|-- doc.md # Add skill-related section
|-- index.md # Update index
+-- examples/
+-- skills/
+-- <skill-name>/
|-- README.md # Example documentation
|-- example-1.ts.template # Code example (use .template suffix)
+-- example-2.tsx.template
File naming conventions:
- Code files:
<name>.<ext>.template(e.g.,component.tsx.template) - Config files:
<name>.config.template(e.g.,tailwind.config.template) - Documentation:
README.md(normal suffix)
4.3 Update Index File
Add to the Quick Navigation table in index.md:
| <Skill-related task> | <Section name> | `skill-<skill-name>` |
5. Generate Integration Report
Skill Integration Report: <skill-name>
# Overview
- Skill description: [Functionality description]
- Integration target:
.trellis/spec/{target}/
# Tech Stack Compatibility
| Skill Requirement | Project Status | Compatibility | |-------------------|----------------|---------------| | [Tech 1] | [Project tech] | [OK]/[!]/[X] |
# Integration Locations
| Type | Path |
|------|------|
| Guidelines doc | .trellis/spec/{target}/doc.md (section: skill-<name>) |
| Code examples | .trellis/spec/{target}/examples/skills/<name>/ |
| Index update | .trellis/spec/{target}/index.md |
{target}=frontendorbackend
# Dependencies (if needed)
# Install required dependencies (adjust for your package manager)
npm install <package>
# or
pnpm add <package>
# or
yarn add <package>
[OK] Completed Changes
- [ ] Added
@@@section:skill-<name>section todoc.md - [ ] Added index entry to
index.md - [ ] Created example files in
examples/skills/<name>/ - [ ] Example files use
.templatesuffix
# Related Guidelines
- [Existing related section IDs]
6. Optional: Create Usage Command
If this skill is frequently used, create a shortcut command:
/trellis:create-command use-<skill-name> Use <skill-name> skill following project guidelines
