Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

everything-copilot-cli copilot-instructions.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

GitHub Copilot Instructions

Concise runtime instructions for GitHub Copilot. For the fuller human-facing reference guide, see COPILOT-INSTRUCTIONS.md in the repository root.


Project Context

This is everything-copilot-cli — a reference repository defining agents, skills, rules, orchestration patterns, and MCP configurations for GitHub Copilot CLI. Content is Markdown and JSON configuration, not application code.

Essential Rules

  1. Use YAML frontmatter in all agent and skill files
  2. Use kebab-case for all filenames (e.g., build-error-resolver.md)
  3. Use conventional commits (feat:, fix:, docs:, chore:)
  4. Run validation before committing: npm run validate && npm run lint:md && npm test
  5. Don't mix concerns — one agent/skill/rule per file, one topic per PR

Directory Structure

Directory Contents
agents/ Agent definitions with persona, tools, model, behavior
skills/ Source skill library. Each skill lives at skills/<category>/<skill-name>/SKILL.md
skills/copilot-exclusive/ Copilot-only capabilities such as plan mode, fleet, background agents, and session memory
skills/development/, skills/workflow/, skills/security/, skills/testing/, skills/documentation/, skills/product/, skills/content/ Portable domain skills grouped by category
rules/common/ Universal behavioral rules
rules/languages/ Language-specific coding standards
rules/frameworks/ Framework-specific guidance

contexts/ Execution context definitions
mcp-configs/ MCP server configurations
examples/ Example copilot-instructions per project type (nextjs-app/, python-api/, dotnet-webapp/, monorepo/)

Agent Type Selection

Use the right Copilot agent type for each task:

Task Type Agent Type Examples
Understanding code/configs explore "What agents are defined?", "How does orchestration work?"
Running builds/tests/lints task "Validate all configs", "Run the test suite"
Complex multi-step changes general-purpose "Add a new agent with skills and tests", "Refactor rule structure"
Reviewing changes code-review "Review this PR", "Check for issues in staged changes"
Parallel independent work Fleet mode "Create example configs for all 4 project types"

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
