agentic-os copilot-instructions.md

Repository instructions for Agentic OS, a project that uses shared guidance files and workflow documents to coordinate coding agents. They identify the canonical instructions, review priorities, and governance paths.

In plain words
What is it for?
They support pull-request reviews and changes involving shared instructions, agent adapters, governance workflows, and guard tests.
Why use it?
They help agents follow the repository’s agreed rules instead of inventing their own process or overlooking important checks.

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.

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

agentic-os 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 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.

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.

What it actually says

Copilot Repository Instructions

Use AGENTS.md as the shared source of truth for this repository's agent behavior. Keep this file short because Copilot code review reads only the early portion of custom instruction files.

Always Apply

  • Follow AGENTS.md ## Review guidelines for PR review priorities.
  • Prefer focused, file/line-specific findings over broad style suggestions.
  • Treat correctness, security, missing tests, governance-bypass, and stale spec/backlog/SSoT metadata as higher priority than formatting.
  • Do not duplicate or reinterpret Agentic OS workflow rules here; refer to AGENTS.md and .agent/workflows/*.md.
  • For governance files, verify that updates preserve canonical paths and include appropriate evidence.

Useful Paths

  • Shared agent contract: AGENTS.md
  • Claude adapter: CLAUDE.md
  • Gemini adapter: GEMINI.md
  • Governance workflows: .agent/workflows/*.md
  • Guard tests: tests/guard/
  • Contributor interaction guide: docs/ai-contributors.md
Changes

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.
