Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00936 | $0.00936 |
| Opus 5 | $0.00468 | $0.00468 |
| Sonnet 5 | $0.00187 | $0.00187 |
| Haiku 4.5 | $0.00094 | $0.00094 |
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 2d ago.
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.
How it starts
The opening of the file, as written. The whole thing — 87 lines — stays where its author put it; the contents beside it link to each section on GitHub.
GitHub Copilot Instructions
Concise runtime instructions for GitHub Copilot. For the fuller human-facing reference guide, see

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

What this file has done since we first saw it
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.

everything-copilot-cli copilot-instructions.md is an instructions file published in the GitHub repository drvoss/everything-copilot-cli (45 stars, last pushed 5d ago), licensed MIT. It adds 936 tokens to every session, about $0.0047 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
