locus: Command for GitHub Copilot

.github/prompts/README.md

README is a command for GitHub Copilot from Nano-Nimbus/locus. It costs 0 tokens per session (282 once invoked), scanned A, original, MIT.

A README for a set of prompts that make AI-assisted GitHub Actions jobs run security checks and prepare pull-request reports. A pull request is a proposed code change waiting for review.

In plain words
What is it for?
It helps configure Claude, Codex, Copilot, or Gemini security-audit jobs in GitHub Actions, including manual and automatic workflows.
Why use it?
It explains how to connect the prompts to different AI providers and where to find the resulting reports, scan files, and review comments.

Command for GitHub Copilot

Written for GitHub Copilot: a Copilot chat mode or prompt. Also seen: mentions Codex.

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

README 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.

What it actually says

Security Audit Prompt Pack (GitHub Actions)

Prompt files in this directory are designed for AI-assisted GitHub Actions jobs that run security tests, vulnerability auditing, and PR reporting.

Prompt Files

  • claude-security-audit.md
  • codex-security-audit.md
  • copilot-security-audit.md
  • gemini-security-audit.md

Expected Artifacts

Each prompt directs the agent to generate:

  1. A full report in docs/audits/
  2. Scanner artifacts in docs/audits/artifacts/
  3. A short PR comment draft in docs/audits/

GitHub Actions Wiring

Use your provider action with prompt_file set to one of these files.

Example step shape:

- name: Security Audit (AI)
  uses: <provider-action>
  with:
    prompt_file: .github/prompts/codex-security-audit.md

Replace <provider-action> with your configured Claude/Codex/Copilot/Gemini Action runner.

Included Workflows

  • Claude manual-only workflow (disabled for automatic PR runs): .github/workflows/claude-security-audit.yml
  • Copilot coding-agent setup workflow: .github/workflows/copilot-setup-steps.yml
  • Auto-comment workflow: .github/workflows/post-ai-security-pr-comment.yml
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.

README is a command published in the GitHub repository Nano-Nimbus/locus (0 stars, last pushed 1mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 282 tokens. 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 2026-09-08.
