logic-lens: Instructions file for Codex

AGENTS.md

logic-lens AGENTS.md is an instructions file for Codex, OpenCode from hyhmrright/logic-lens. It costs 304 tokens per session, scanned A, original, MIT.

Developer instructions for Logic-Lens, a Codex command-line project with skills that inspect code logic and explain how it runs.

In plain words
What is it for?
Use them when invoking logic review, execution explanations, semantic comparisons, fault location, health checks, or the combined fix pipeline.
Why use it?
They define the project structure and a fixed format for reporting findings, making reviews consistent and preventing made-up risk categories.

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

This is hyhmrright/logic-lens's own configuration. It tells Codex and OpenCode how to work on logic-lens 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 logic-lens 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

logic-lens 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.

What it actually says

Logic-Lens — Developer Guide (Codex CLI)

This file contains instructions for Codex CLI agents working on the Logic-Lens repository.

Invoking Skills

In Codex CLI, invoke skills with the $ prefix:

$logic-review    — logic bug review
$logic-explain   — execution path explanation
$logic-diff      — semantic equivalence check
$logic-locate    — fault localization
$logic-health    — aggregate logic health dashboard
$logic-fix-all   — autonomous audit-and-fix pipeline

Project Layout

See CLAUDE.md for the full layout. The core content lives in skills/ as platform-agnostic Markdown. Codex-specific metadata is in .codex-plugin/plugin.json.

Key Conventions

  • skills/_shared/ is the shared framework. Do not duplicate its content in individual skill guides.
  • Every finding in a review output must use the Premises → Trace → Divergence → Trigger → Remedy format (Iron Law).
  • Risk codes L1–L9 are defined in skills/_shared/logic-risks.md. Do not invent new codes without updating that file.
  • Version number in package.json is the source of truth — keep all metadata files in sync.

No Hooks

The session-start hook in hooks/ is Claude Code only. Codex CLI discovers skills via .codex-plugin/plugin.json and does not use the hook system.

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.
