AGENTS.md

ijfw AGENTS.md is an instructions file for Codex, OpenCode from FerroxLabs/ijfw. It costs 5,150 tokens per session, scanned A, original, MIT.

Shared project instructions for IJFW, stored in AGENTS.md and reused by configuration files for several AI coding tools.

In plain words
What is it for?
Use them when working on IJFW documentation, platform adapters, project memory, tests, release checks, or publishing decisions.
Why use it?
They provide the canonical project rules, memory location, release status, and verification results so agents use one consistent source of guidance.

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

This is FerroxLabs/ijfw's own configuration. It tells Codex and OpenCode how to work on ijfw 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 ijfw 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

ijfw 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

AGENTS.md

This file follows the open AGENTS.md spec (https://agents.md/) and is the canonical agent-instructions surface for this project. Platform-specific files (CLAUDE.md, GEMINI.md, WAYLAND.md, codex/AGENTS.md, .cursorrules, .windsurfrules, copilot-instructions.md) are thin adapters that point here.

Four IJFW-managed regions live in this file. Content outside the markers is yours -- IJFW will never touch it.

Project memory at .ijfw/memory/. Call ijfw_memory_prelude for full context.

Last handoff: IJFW 1.3.2 RC audit/verify pass is complete locally. The 1.3.1 release caution still applies: user explicitly said, "When windows completes and verifies we go forward. Remember that". Do NOT create/push tags or attempt npm publish until Windows CI/release clearance is explicitly given by the user. Current 1.3.2 verification has passed 880/880 Node tests, 158/158 focused regression tests, package dry-runs, temp-project swarm E2E, cross-audit reconciliation, platform drift, diff hygiene, and preflight blocking gates. Findings fixed during audit: hermetic update-confirm npm test PATH, Trident EPIPE hardening, workflow bootstrap/fallback guidance, team/AGENTS mirroring specificity, Codex dispatch command order, and memory/release-gate consistency. Advisory warnings only: eslint-security non-literal fs warnings in installer paths and PSScriptAnalyzer skipped because pwsh unavailable locally. No tag or publish performed.

No project agents yet. Run ijfw team to set them up.

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.
