code-cortex-loop: Instructions file for Codex

AGENTS.md

code-cortex-loop AGENTS.md is an instructions file for Codex, OpenCode from whitequeen306/code-cortex-loop. It costs 1,601 tokens per session, scanned A, original, MIT.

Instructions for CodeCortexLoop, a code-quality workflow that scores findings and includes security and refactoring checks. A quality finding must include evidence and a confidence level.

In plain words
What is it for?
Use them when running cortexloop commands, reviewing findings, performing security checks, establishing a baseline, or making refactors.
Why use it?
They prevent speculative issues from being treated as real defects and set baseline checks for safer code changes.

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions subagents; mentions Claude Code; mentions AGENTS.md.

This is whitequeen306/code-cortex-loop's own configuration. It tells Codex and OpenCode how to work on code-cortex-loop 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 code-cortex-loop 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

code-cortex-loop AGENTS.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 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.

CodeCortexLoop — Agent Rules

These rules apply when running any /cortexloop* command. Tool-specific installs copy this to the appropriate rules directory or merge into project AGENTS.md.

When CodeCortexLoop Runs

  1. Load cortexloop.config.json from project root (optional)
  2. Load .cortexloopignore (optional)
  3. Follow cortexloop-workflow for severity, scoring, CI, re-verify, and post-processing
  4. Follow refactor-safety for all code modifications
  5. Follow baseline-policy when using /cortexloop-baseline or ci.baseline
  6. Follow learning-loop when querying or recording playbook entries

Finding Quality Gate

Every scored finding must include:

  • Evidence: trigger path, measurement, test gap, static proof, or audit output
  • Confidence: high or medium

Low-confidence speculation must not become a scored finding. Put it in Open Questions or drop it.

Security Baseline (always during security pass)

Every code change must satisfy:

  1. User input sanitized at boundaries
  2. SQL parameterized (no string concatenation)
  3. No secrets in code, logs, or git
  4. Error messages must not leak internals
  5. File uploads restricted (type, size, path)
  6. External URLs validated (SSRF prevention)

Refactor Safety (Direct mode)

  • Preserve behavior exactly during simplify/perf passes
  • Chesterton's Fence: understand before removing
  • Ask before deleting dead code or dependencies
  • Separate refactors from bug fixes
  • Run tests after each logical change group; revert on failure

Suppression

  • Project: .cortexloopignore (gitignore syntax)
  • Inline: // cortexloop-ignore CL-001 or # cortexloop-ignore CL-001
  • Never suppress Critical without explicit user approval

CI Gate

After CI report generation:

node scripts/ci-gate.mjs docs/cortexloop/report.json
# Baseline ratchet (new findings only):
node scripts/baseline.mjs diff docs/cortexloop/report.json
node scripts/ci-gate.mjs docs/cortexloop/report.json --baseline

Exit codes: 0 pass, 1 Critical, 2 High over threshold, 3 report error.

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.
