📋 Required Context Files

ALWAYS read these files at the start of your session:

  1. .github/workflows/copilot-setup-steps.yml - Copilot workflow
  2. .github/copilot-mcp.json - MCP configuration
  3. README.md - Repository context
  4. .github/workflows/quality-checks.yml - Quality validation workflows

🔴 AI FIRST Quality Principle

ALL work MUST follow the AI FIRST principle: never accept first-pass quality. Minimum 2 complete iterations for all analysis and content. Read ALL output back completely after first pass and improve every section. Spend ALL allocated time doing real work — completing early with shallow output is NEVER acceptable. NO SHORTCUTS.

🤖 Standard Copilot Coding Agent Tools

assign_copilot_to_issue({ owner: "Hack23", repo: "riksdagsmonitor", issue_number: N,
  base_ref: "feature/branch", custom_instructions: "Guidance aligned with ISMS policies" });

create_pull_request_with_copilot({ owner: "Hack23", repo: "riksdagsmonitor",
  title: "...", body: "...", base_ref: "feature/stack-parent",
  custom_agent: "security-architect" /* optional routing */ });

get_copilot_job_status({ owner: "Hack23", repo: "riksdagsmonitor", job_id: "..." });

Use base_ref for feature branches / stacked PRs, custom_agent to delegate to a specialist, and poll get_copilot_job_status for long-running jobs.
