dox AGENTS.md

A set of instructions for agents using the DOX documentation framework. AGENTS.md files are repository instructions that apply to the folders beneath them.

In plain words
What is it for?
Use it when working in a repository that uses AGENTS.md files to define editing rules, file ownership, and documentation updates.
Why use it?
It helps an agent follow the right instructions before editing files and keep documentation current after meaningful changes.

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

dox 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 today.

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.

How it starts

The opening of the file, as written. The whole thing — 84 lines — stays where its author put it; the contents beside it link to each section on GitHub.

DOX framework

  • DOX is highly performant AGENTS.md hierarchy installed here
  • Agent must follow DOX instructions across any edits

Core Contract

  • AGENTS.md files are binding work contracts for their subtrees
  • Work products, source materials, instructions, records, assets, and durable docs must stay understandable from the nearest applicable AGENTS.md plus every parent AGENTS.md above it

Read Before Editing

  1. Read the root AGENTS.md
  2. Identify every file or folder you expect to touch
  3. Walk from the repository root to each target path
  4. Read every AGENTS.md found along each route
  5. If a parent AGENTS.md lists a child AGENTS.md whose scope contains the path, read that child and continue from there
  6. Use the nearest AGENTS.md as the local contract and parent docs for repo-wide rules
  7. If docs conflict, the closer doc controls local work details, but no child doc may weaken DOX

Do not rely on memory. Re-read the applicable DOX chain in the current session before editing.

Update After Editing

Every meaningful change requires a DOX pass before the task is done.

Update the closest owning AGENTS.md when a change affects:

  • purpose, scope, ownership, or responsibilities
  • durable structure, contracts, workflows, or operating rules
  • required inputs, outputs, permissions, constraints, side effects, or artifacts
  • user preferences about behavior, communication, process, organization, or quality
  • AGENTS.md creation, deletion, move, rename, or index contents

Update parent docs when parent-level structure, ownership, workflow, or child index changes. Update child docs when parent changes alter local rules. Remove stale or contradictory text immediately. Small edits that do not change behavior or contracts may leave docs unchanged, but the DOX pass still must happen.

Hierarchy

  • Root AGENTS.md is the DOX rail: project-wide instructions, global preferences, durable workflow rules, and the top-level Child DOX Index
  • Child AGENTS.md files own domain-specific instructions and their own Child DOX Index
  • Each parent explains what its direct children cover and what stays owned by the parent
  • The closer a doc is to the work, the more specific and practical it must be

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.
