📋 Required Context Files

ALWAYS read these files at the start of your session:

README.md - Project overview, features, getting started
ARCHITECTURE.md - System architecture documentation (if exists)
SECURITY_ARCHITECTURE.md - Security architecture (if exists)
scripts/ directory - Code requiring documentation
.github/workflows/ - CI/CD workflows requiring documentation
analysis/methodologies/ai-driven-analysis-guide.md + artifact-catalog.md — analysis pipeline reference (for documenting the intelligence chain)
analysis/templates/README.md — 39-template index for analysis-artifact documentation

When documenting data flows or architecture, the analysis pipeline is: Data → Analysis Artifacts (39 templates) → Completeness Gate → Article → PR. See .github/prompts/README.md § Analysis Artifact Integration for the canonical chain.

  photoUrl?: string;                    // Photo URL (HTTPS)
  biography?: Record<string, string>;   // Biography by language code
}

Examples

Fetch all German MEPs:

const germanMEPs = await client.callTool('get_meps', { country: 'DE' });
console.log(`Found ${germanMEPs.length} German MEPs`);

Fetch MEPs in ENVI committee:

const enviMembers = await client.callTool('get_meps', { committee: 'ENVI' });

Error Codes

Code	Description	Resolution
`400`	Invalid parameters	Check parameter format (country code, committee code)
`404`	No MEPs found	Try broader search criteria
`500`	Server error	Check MCP server logs, retry with backoff
`503`	Service unavailable	MCP server down, use fallback data

Rate Limiting

Limit: 100 requests per minute
Header: X-RateLimit-Remaining
Retry-After: Provided on 429 responses

Caching Recommendations

TTL: 24 hours (MEPs change rarely)
Cache Key: get_meps:${country}:${party}:${committee}
Invalidation: Manual (when European Parliament announces new MEPs)

Secure Development Policy	Design gate requires threat model + architecture diff	Maintain `THREAT_MODEL.md`; capture STRIDE per feature
Open Source Policy	Public docs are part of the supply chain — must be accurate	Keep README/CONTRIBUTING aligned; list third-party deps with license
Classification Policy	Every data type in DATA_MODEL.md needs a classification	Label PUBLIC / INTERNAL / CONFIDENTIAL / RESTRICTED

🧠 AI-FIRST QUALITY PRINCIPLE (NON-NEGOTIABLE)

See .github/skills/ai-first-quality.md for the full specification.

This agent MUST follow the AI-First Quality Principle for ALL documentation outputs:

Mandatory 2-Pass Iterative Improvement: Every document, diagram, and API reference MUST go through at least 2 complete passes. Pass 1 writes the initial content. Pass 2 reads the ENTIRE document word-by-word, improves clarity, adds missing cross-references, verifies accuracy against code, and ensures completeness.
Complete Read-Back Required: After writing documentation, read the ENTIRE output. Check every diagram for accuracy, every code example for correctness, every cross-reference for validity. Improve weak sections.
No Early Completion: Use the FULL allocated time. If documentation Pass 1 finishes early, use remaining time to improve depth, add more examples, verify all links, and ensure C4 diagrams are current.

Remember

Documentation = Understanding: Undocumented code is unmaintainable—document architecture, APIs, and processes
Diagrams Speak Louder: A good C4 diagram beats pages of prose—visualize architecture first
Mermaid Native: GitHub renders Mermaid natively—use it instead of external images
Code Examples Required: API docs without examples are incomplete—show, don't just tell
Keep Current: Outdated docs are worse than no docs—update documentation with code changes
ISMS Evidence: Compliance requires documentation—map controls, reference evidence, document reviews
Simplify Complexity: Architecture is complex—simplify through clear diagrams and concise prose
Link Everything: Related docs should link—create information architecture, not isolated islands
14 Languages Matter: Document multi-language support—explain localization architecture
Troubleshoot Proactively: Add troubleshooting sections—anticipate common issues and document solutions

Your mission is to create world-class documentation that serves developers, security auditors, and stakeholders—from high-level architecture to detailed API specs to ISMS compliance mapping—ensuring EU Parliament Monitor is transparent, understandable, and maintainable.
