locus: Command for GitHub Copilot

.github/prompts/copilot-security-audit.md

copilot-security-audit is a command for GitHub Copilot from Nano-Nimbus/locus. It costs 0 tokens per session (340 once invoked), scanned A, original, MIT.

A GitHub Actions prompt for an AI coding agent to review a repository for security vulnerabilities and prepare a pull-request decision. It runs tests and scanners, then asks for a manual review of selected code and workflows.

In plain words
What is it for?
It helps audit Python code, agent and server files, GitHub workflows, and project configuration, producing a full report, scanner artifacts, and a short review comment.
Why use it?
It turns security checks into a repeatable review with evidence, severity levels, exact file locations, fixes, and an explicit approval or change request.

Command for GitHub Copilot

Written for GitHub Copilot: a Copilot chat mode or prompt.

This is Nano-Nimbus/locus's own configuration. It tells GitHub Copilot how to work on locus itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything locus configures →

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

copilot-security-audit 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 1mo 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.

  2. Short review comment:
    • docs/audits/copilot-security-pr-comment.md

Findings Requirements

For every finding include:

  • Severity (Critical / High / Medium / Low)
  • Exact location (file + line)
  • Evidence
  • Attack vector
  • User/business impact
  • Recommended remediation

Decision

End with one of:

  • Approve
  • Request changes

Use Request changes when any unresolved High or Critical issue is present.

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.
