forensic-deepdive: Instructions file for Codex

AGENTS.md

forensic-deepdive AGENTS.md is an instructions file for Codex, OpenCode from Dhevenddra/forensic-deepdive. It costs 328 tokens per session, scanned A, original, Apache-2.0.

A set of instructions for coding agents working in the forensic-deepdive repository. It defines which project files to read, how related instruction files must stay synchronized, and what to record after each session.

In plain words
What is it for?
Use it to guide repository startup checks, keep CLAUDE.md and AGENTS.md aligned, record progress and decisions, and follow the project's commit conventions.
Why use it?
It prevents agents from missing important project decisions, using the wrong operating rules, or leaving undocumented changes behind.

Instructions file for CodexOpenCode

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

This is Dhevenddra/forensic-deepdive's own configuration. It tells Codex and OpenCode how to work on forensic-deepdive 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 forensic-deepdive 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

forensic-deepdive 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 2mo 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

AGENTS.md

This file mirrors CLAUDE.md. Single source of truth lives in CLAUDE.md; this file is provided for cross-tool compatibility (Codex CLI, Cursor, Continue, Aider, Factory Droid, Gemini CLI, GitHub Copilot CLI, Jules, VS Code) since the Linux Foundation's Agentic AI Foundation (December 2025) standardized on AGENTS.md.

Read both this file and CLAUDE.md. If they ever drift, CLAUDE.md wins.

Cross-edit obligation

  • Change CLAUDE.md → also update this file in the same commit.
  • A scripts/sync-agents-md.sh script (added in v0.2) will enforce this with a pre-commit hook.

Mandatory reading order at session start

  1. CLAUDE.md — operating manual
  2. DECISIONS.md — architectural decisions you cannot violate
  3. PROGRESS.md — current state and next steps
  4. git log --oneline -10

Mandatory action at session end

  1. Append a dated entry to PROGRESS.md.
  2. If a non-trivial decision was made, append a DEC-NNN entry to DECISIONS.md.
  3. Conventional-commit message (feat:, fix:, chore:, docs:, test:, refactor:).
  4. Never push without explicit user instruction.

(For the full operating manual, see CLAUDE.md.)

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.
