name: skill-proposer description: Analyzes PRD to propose relevant AI skills for a project. Trigger: Before starting app development, after brainstorming, or when user asks for skill recommendations based on a PRD. license: MIT metadata: author: Pablo Lozano version: "0.3" scope: [root] auto_invoke: - "After creating/modifying a PRD" - "After using the brainstorming skill before the implementation begins" - "User asks to propose skills based on a PRD or project description" allowed-tools: Read, Edit, Write, Glob, Grep, WebFetch, WebSearch, context7_resolve-library-id, context7_query-docs

When to Use

Use this skill when:

• Starting a new project and need to identify which skills will help the AI agent
• After brainstorming an app idea and before implementation begins
• User asks to propose skills based on a PRD or project description
• Evaluating what context the AI agent will need for optimal performance

Critical Patterns

• ALWAYS ask clarifying questions if tech stack is unclear — never guess
• Prioritize hallucination-prone technologies — React, Next.js, FastAPI, etc. change frequently
• Security-focused skills are always High priority — auth, validation, encryption
• Link must point to actual URL found or use "—" (never invent URLs)
• User is responsible for skill verification — always show security warning

Decision Trees

When to Ask Questions vs Proceed

Situation	Action
Primary language identified	Proceed
Framework(s) identified	Proceed
Database identified	Proceed
Architecture type known	Proceed
Any of above missing	ASK before proceeding

How to Determine Priority

Condition	Priority
Core technology + changes frequently	High
Security-related (auth, encryption)	High
Complex API / syntax	High
Important but stable	Medium
Good public documentation exists	Medium
Nice-to-have or very stable	Low

When to Include a Link

Situation	Link Field
Found excellent match in skillsmp.com	Full URL
Found excellent match in skills.sh	Full URL
Found relevant Context7 docs	— (mention in notes)
No search performed	—
No good match found	—

Workflow

Phase 0: Clarification (If Needed)

Before analyzing, assess whether the project description is clear enough. Ask the user questions if:

• Tech stack is unclear or ambiguous

  • "Which programming language(s) do you plan to use?"
  • "Which framework(s) are you considering for the frontend/backend?"

• Architecture decisions are missing

  • "Are you planning a monolithic architecture, microservices, or serverless?"
  • "What type of database are you planning to use?"

• Scale and complexity are unknown

  • "Is this a personal project, startup MVP, or enterprise application?"
  • "Do you need authentication, authorization, or multi-tenancy?"

• Quality requirements are not specified

  • "What level of test coverage are you aiming for?"
  • "Do you have specific performance requirements?"

Important: Ask questions BEFORE proceeding with analysis.

Phase 1: Tech Stack Analysis

Identify and document:

• Programming languages and specific versions
• Frameworks and core libraries (frontend, backend, mobile...)
• Databases and persistence solutions
• Infrastructure and deployment (Docker, Kubernetes, CI/CD...)
• Development tools (testing, linting, build tools...)

Phase 2: Pattern and Architecture Analysis

• Architecture type (monolith, microservices, serverless, event-driven...)
• Relevant development patterns (TDD, DDD, SDD, Clean Architecture, Hexagonal...)
• Quality requirements (testing, security, performance, observability)
• Applicable conventions and standards

Phase 3: Skill Needs Identification

For each technology, pattern, or process identified, ask yourself:

1. Does this technology change frequently? → Needs updated skill
2. Does it have complex syntax or APIs? → Needs skill with examples
3. Is it critical for project success? → High priority
4. Can the agent easily hallucinate here? → Needs specific context

Phase 4: Existing Skills Search (Optional)

If considered useful, search in:

• https://skillsmp.com/ — Skills marketplace
• https://skills.sh/ — Skills marketplace
• Context7 — MCP for up-to-date library documentation

Output Format

Present a table with the proposed skills:

Skill	Technology/Process	Reason	Priority	Link
Descriptive name	Technology or process covered	Brief justification	High/Medium/Low	URL or "—"

Security Warning

⚠️ IMPORTANT — User Responsibility:

Before adding any skill to your project:

1. Read the complete code of the downloaded skill
2. Verify it contains no prompt injection or malicious instructions
3. Understand what permissions it has and which tools it can use
4. Confirm it comes from a trusted source

The agent can propose, but you decide which skills to use. Skills are added manually under your responsibility.

---

Delegation to skill-creator

If the user requests to create a custom skill instead of using an existing one:

"To create this skill, use the skill-creator skill which will guide you through the generation process."

Do not create skills directly from this skill. Only identify needs and propose.

• Skills Marketplaces: skillsmp.com, skills.sh
• Documentation Lookup: Context7 MCP for up-to-date library documentation
• Skill Creation: Use skill-creator skill to generate custom skills

Usage Example

User input:

"I'm going to develop a REST API with FastAPI, PostgreSQL, and JWT authentication. The frontend will be React with TypeScript."

Expected output:

Skill	Technology/Process	Reason	Priority	Link
fastapi-best-practices	FastAPI	Framework with specific patterns and frequent updates	High	https://skills.sh/wshobson/agents/fastapi-templates
pydantic-validation	Pydantic	Core data validation in FastAPI, syntax changes between versions	High	—
jwt-auth-python	JWT + Python	Auth implementation prone to security errors	High	https://skills.sh/mindrally/skills/jwt-security
sqlalchemy-modern	SQLAlchemy + PostgreSQL	ORM with syntax that varies between versions	High	—
react-typescript-patterns	React + TypeScript	Modern hooks patterns, generic types	High	https://skills.sh/vercel-labs/agent-skills/vercel-react-best-practices
testing-fastapi	pytest + FastAPI	API testing with specific fixtures and mocks	Medium	—
