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 | $0.03614 | $0.03614 |
| Opus 5 | $0.01807 | $0.01807 |
| Sonnet 5 | $0.00723 | $0.00723 |
| Haiku 4.5 | $0.00361 | $0.00361 |
Grade F, and why
copilot-governance copilot-instructions.md scanned grade F with 4 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 3d 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.

Copilot Instructions — copilot-governance
Purpose and Core Problem
This repo solves cross-platform, cross-machine AI governance: ensuring that any AI coding platform on any machine receives the same global instructions, skills, agents, and lifecycle hooks — without duplication or manual per-machine setup.
The strategic challenge: Different AI IDE platforms have different global-config formats and install paths. This repo packages global-items so they are easily installed once and auto-updating on every new machine, for any number of platforms and users.
Currently wired: VS Code Copilot, Claude Code, and Google Antigravity. The architecture accommodates any additional platform that supports file-based rules and a skills directory — adding one means writing a template rules file and one install.sh stanza. No skill files change.
Platform Landscape (April 2026)
The following platforms are currently wired. This list is not exhaustive — any platform that reads a markdown rules file and loads skills from a directory can be added.
| Platform | Global Config Root | Skills Path | Rules/Instructions | Hooks |
|---|---|---|---|---|
| VS Code Copilot | ~/.copilot/ (via settings) |
~/.copilot/skills/ |
~/.copilot/instructions/ |
~/.copilot/hooks/global-standards.json |
| Claude Code | ~/.claude/ |
~/.claude/skills/ (also reads .agents/skills/) |
~/.claude/CLAUDE.md, ~/.claude/rules/ |
~/.claude/settings.json → hooks key |
| Google Antigravity | ~/.gemini/ |
~/.gemini/antigravity/skills/ |
~/.gemini/GEMINI.md, .agents/rules/ |
Not yet documented |
| Any platform | ~/.yourplatform/ |
symlink → skills/ |
template rules file via envsubst |
platform-specific |
Key insight: Any platform that implements the agentskills.io open standard consumes the same SKILL.md format. Skills in skills/*/SKILL.md require zero per-platform variants — the install path is the only variable.
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.

copilot-governance copilot-instructions.md is an instructions file published in the GitHub repository chf3198/copilot-governance (1 stars, last pushed 1mo ago), licensed MIT. It adds 3,614 tokens to every session, about $0.0181 per session on Opus 5. A static security scan graded it F with 4 findings (downloads and executes remote code, reads agent configuration directories, recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
