This skill researches industry standards and architectural patterns using MCP Ref to generate Standards Research for Story Technical Notes.

When to Use This Skill

This skill should be used when:

  • Need to research standards and patterns BEFORE Story generation (ensures tasks follow industry best practices)

  • Epic Technical Notes mention specific standards requiring documentation (OAuth, OpenAPI, WebSocket)

  • Prevent situations where tasks use outdated patterns or violate RFC compliance

  • Reusable for ANY skill requiring standards research (ln-220-story-coordinator, ln-300-task-coordinator, ln-510-test-planner, ln-002-best-practices-researcher)

Who calls this skill:

  • ln-220-story-coordinator (Phase 3) - research for Story creation

  • ln-300-task-coordinator (optional) - research for complex Stories

  • ln-510-test-planner (optional) - research for test task planning

  • Manual - user can invoke directly for Epic/Story research

How It Works

The skill follows a 6-phase workflow focused on standards and architectural patterns.

Stack Detection → Identify → Ref Research → Existing Guides → Standards Research

Phase 0: Stack Detection

Objective: Determine project stack BEFORE research to filter queries.

Detection:

| *.csproj, *.sln | .NET | "C# ASP.NET Core"

| package.json + tsconfig.json | Node.js | "TypeScript Node.js"

| requirements.txt, pyproject.toml | Python | "Python"

| go.mod | Go | "Go Golang"

| Cargo.toml | Rust | "Rust"

| build.gradle, pom.xml | Java | "Java"

Process:

  • Check context_store.TECH_STACK if provided → use directly

  • Else: Glob for indicator files in project root

  • Store detected_stack.query_prefix for Phases 2-3

Output: detected_stack = {language, framework, query_prefix}

Skip conditions: If no stack detected → proceed without prefix (generic queries)

Phase 1: Identify Libraries

Objective: Parse Epic/Story for libraries and technology keywords.

Process:

  • Read Epic/Story description (provided as input)

Parse Epic Technical Notes for mentioned libraries/frameworks

  • Parse Epic Scope In for technology keywords (authentication, rate limiting, payments, etc.)

  • Identify Story domain from Epic goal statement (e.g., "Add rate limiting" → domain = "rate limiting")

  • Extract library list:

Primary libraries (explicitly mentioned)

  • Inferred libraries (e.g., "REST API" → FastAPI, "caching" → Redis)

  • Filter out well-known libraries with stable APIs (e.g., requests, urllib3)

  • Determine Story domain:

Extract from Epic goal or Story title

  • Examples: rate limiting, authentication, payment processing, file upload

Output: Library list (3-5 libraries max) + Story domain

Skip conditions:

  • NO libraries mentioned in Epic → Output empty Research Summary

  • Trivial CRUD operation with well-known libraries → Output empty Research Summary

  • Epic explicitly states "research not needed" → Skip

Phase 2: MCP Ref Research

Objective: Get industry standards and architectural patterns.

Process:

  • Focus on standards/RFCs:

Call mcp__Ref__ref_search_documentation(query="[detected_stack.query_prefix] [story_domain] RFC standard specification")

  • Example: "C# ASP.NET Core rate limiting RFC standard specification"

  • Extract: RFC/spec references (OAuth 2.0 RFC 6749, OpenAPI 3.0, WebSocket RFC 6455)

  • Focus on architectural patterns:

Call mcp__Ref__ref_search_documentation(query="[detected_stack.query_prefix] [story_domain] architectural patterns best practices")

  • Example: "TypeScript Node.js authentication architectural patterns best practices"

  • Extract: Middleware, Dependency Injection, Decorator pattern

Output: Standards compliance table + Architectural patterns list

Phase 3: MCP Ref Research

Objective: Get industry standards and best practices.

Process:

  • FOR EACH library + Story domain combination:

Call mcp__Ref__ref_search_documentation(query="[detected_stack.query_prefix] [library] [domain] best practices 2025")

  • Call mcp__Ref__ref_search_documentation(query="[detected_stack.query_prefix] [domain] industry standards RFC")

  • Example: "C# ASP.NET Core Polly rate limiting best practices 2025"

  • Extract from results (NO CODE - text/tables only):

Industry standards (RFC/spec references: OAuth 2.0, REST API, OpenAPI 3.0)

  • Common patterns (do/don't descriptions, anti-patterns to avoid)

  • Integration approaches (middleware, dependency injection, decorators)

  • Security considerations (OWASP compliance, vulnerability mitigation)

  • Official docs URLs (link to stack-appropriate authoritative sources)

  • Store results for Research Summary compilation

Output: Standards compliance table (RFC/Standard name, how to comply) + Best practices list

Phase 4: Scan Existing Guides

Objective: Find relevant pattern guides in docs/guides/ directory.

Process:

  • Scan guides directory:

Use Glob to find docs/guides/*.md

  • Read guide filenames

  • Match guides to Story domain:

Match keywords (e.g., rate limiting guide for rate limiting Story)

  • Fuzzy match (e.g., "authentication" matches "auth.md", "oauth.md")

  • Collect guide paths for linking in Technical Notes

Output: Existing guides list (relative paths from project root)

Phase 5: Generate Standards Research

Objective: Compile research results into Standards Research for Story Technical Notes subsection.

NO_CODE Rule: No code snippets. Use tables + links to official docs only.

Format Priority:

┌─────────────────────────────────────┐
│ 1. TABLES + ASCII diagrams ← Priority │
│ 2. Lists (enumerations only)        │
│ 3. Text (last resort)               │
└─────────────────────────────────────┘

Output Format (Table-First):

## Standards Research

**Standards compliance:**

| Standard | Requirement | How to Comply | Reference |
|----------|-------------|---------------|-----------|
| RFC 6749 | OAuth 2.0 | Use PKCE for public clients | [RFC 6749](url) |
| RFC 6585 | Rate Limiting | Return 429 + Retry-After | [RFC 6585](url) |

**Architectural patterns:**

| Pattern | When to Use | Reference |
|---------|-------------|-----------|
| Middleware | Request interception | [Official docs](url) |
| Decorator | Cross-cutting concerns | [Official docs](url) |

**Existing guides:**
- [guide_path.md](guide_path.md) - Brief description

Return Standards Research to calling skill (ln-220, ln-310, ln-350)

Output: Standards Research (Markdown string) for insertion into Story Technical Notes subsection

Important notes:

  • Focus on STANDARDS and PATTERNS only (no library details - libraries researched at Task level)

  • Prefer official docs and RFC standards over blog posts

  • Link to stack-appropriate docs (Microsoft docs for .NET, MDN for JS, etc.)

  • If Standards Research is empty (no standards/patterns) → Return "No standards research needed"

Integration with Ecosystem

Called by:

  • ln-220-story-coordinator (Phase 2) - research for ALL Stories in Epic

  • ln-300-task-coordinator (optional) - research for complex technical Stories

  • ln-510-test-planner (optional) - research for test infrastructure

Dependencies:

  • MCP Ref (ref_search_documentation) - industry standards and patterns

  • Glob (scan docs/guides/)

Input parameters (from calling skill):

  • epic_description (string) - Epic Technical Notes + Scope In + Goal

  • story_domain (string, optional) - Story domain (e.g., "rate limiting")

Output format:

  • Markdown string (Standards Research for Technical Notes subsection)

  • Format: Standards + Patterns (libraries researched at Task level)

Time-Box and Performance

Time-box: 15-20 minutes maximum per Epic

Performance:

  • Research is done ONCE per Epic

  • Results reused for all Stories (5-10 Stories benefit from single research)

  • Parallel MCP calls when possible (Context7 + Ref)

Token efficiency:

  • Context7: max 3000 tokens per library

  • Total: ~10,000 tokens for typical Epic (3-4 libraries)

References

Tools:

  • mcp__Ref__ref_search_documentation() - Search best practices and standards

  • Glob - Scan docs/guides/ directory
