odin-reflector AGENTS.md

odin-reflector AGENTS.md is an instructions file for Claude Code, Codex, OpenCode from OutlineDriven/odin-reflector. It costs 3,750 tokens per session, scanned A, original, Apache-2.0.

Repository instructions for a code-review tool called Codex Reflector, which checks proposed changes through Claude/Cursor hooks and an oh-my-pi extension. Hooks are automated actions that run at specific points while an agent works.

In plain words
What is it for?
Use them when changing review decisions, prompts, redaction, sandboxing, stop enforcement, model settings, or changed-file handling across either integration.
Why use it?
They prevent fixes from being made in the wrong implementation and help keep the Python and TypeScript versions consistent.

Instructions file for Claude CodeCodexOpenCode

Written for Claude Code and Codex and OpenCode: PostToolUse hook event, but also runs codex exec. Also seen: reads .claude/ paths; mentions subagents; names the ExitPlanMode tool.

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

odin-reflector 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 6d 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.

Codex Reflector Agent Notes

This file is only for repo-specific constraints that are easy to break and expensive to rediscover. README owns installation and user-facing usage; do not duplicate it here.

Surface split

  • Rule: Treat the repository as two hook surfaces, not one implementation. The Claude/Cursor plugin is scripts/codex-reflector.py wired by hooks/hooks.json; the oh-my-pi port is omp/codex-reflector.ts loaded through package.json omp.extensions. Why: Both surfaces call codex exec and expose the same reflector idea, but their hook delivery and stop-enforcement mechanisms differ. Editing the wrong surface fixes nothing.

  • Rule: For shared behavior changes, check both surfaces before declaring parity: verdict parsing, prompt builders, redaction/sandboxing, stop-review enforcement, model/effort gating, and changed-file target resolution. Why: The TypeScript file is a native port of the Python hook, while the OMP tests codify port-specific contracts. Silent drift produces different review outcomes for Claude/Cursor vs OMP users.

  • Rule: Any shipped OMP or Claude plugin code/config change bumps the paired release manifests in the same commit: the OMP version (package.json version) and the Claude plugin version in all three Claude fields (.claude-plugin/plugin.json version, plus both version and plugins[0].version in .claude-plugin/marketplace.json); also refresh any marketplace metadata.lastUpdated date present. Shared Python hook changes also bump the Cursor plugin version in all three Cursor fields (.cursor-plugin/plugin.json version, plus both version and plugins[0].version in .cursor-plugin/marketplace.json). Why: The OMP and Claude surfaces ship independently but evolve together, so bumping only one side hides paired release changes from users inspecting either manifest. The Python hook code also powers Cursor; Cursor manifests are tracked source, but they should move when the shared Python/Cursor surface changes rather than on OMP-only 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.
