What is APEX AGENTS.md?

A set of project instructions for AI coding agents, including project details, coding conventions, architecture rules, and workflow requirements. It treats the AGENTS.md file as the project’s shared memory.

It guides branching, validation, pull-request preparation, commit messages, task boundaries, secret handling, and failing-test responses.

It keeps changes aligned with the repository’s standards and reduces risks such as unreviewed work, leaked credentials, or broken tests being ignored.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00217	$0.00217
Opus 5.5	$0.00087	$0.00087
Sonnet 5.5	$0.00043	$0.00043
Haiku 4.5	$0.00022	$0.00022

Security

Grade A, and why

APEX 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.

AGENTS.md — Project Intelligence

This file is the project's living memory. It is read by AI agents before every task. Rules are added automatically via apex-learn when patterns are discovered. Do not delete rules without understanding why they were added.

Workflow

Always create a feature branch before making changes
Run the full validation chain (lint, types, tests, build) before committing
Open draft PRs for review — never push directly to main
Write descriptive commit messages: type(scope): description

Boundaries

Never modify files outside the assigned task scope
Never commit secrets, API keys, or credentials
Never remove failing tests — fix them or flag for review
Never push to main or production branches directly

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.
