ADD: Instructions file for Codex

AGENTS.md

ADD AGENTS.md is an instructions file for Codex, OpenCode from pilotspace/ADD. It costs 505 tokens per session, scanned A, original, MIT.

Instructions for ADD, an AI-driven development process in which the agent drives implementation while a person sets direction and checks the result. It organizes each task into a specification, a contract, tests, and scenarios before building.

In plain words
What is it for?
Use it to orient an agent in an ADD project, identify the current phase, draft and verify task specifications, and coordinate worker and adviser agents.
Why use it?
It gives the agent a defined place to resume work and rules for keeping approved requirements and tests intact. It also stops work when a security issue is found.

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: reads .claude/ paths.

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

ADD 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 28d 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

ADD — how to work in this repo

This project uses ADD (AI-Driven Development): the AI plans, builds and verifies; the human owns direction and reviews the result. There is no CLI. The method is one skill file (.claude/skills/add/SKILL.md), run with files, git and the project's own test command.

Orient first, every session: read .add/PROJECT.md (goal:, invariants:, test_cmd:), then the open task and milestone files under .add/tasks/ and .add/milestones/ (any status: that is not done or dropped), and the last few commits. Resume an open task; otherwise size the work.

Size the work. You route and go; the human reviews after.

the request lane what persists
mechanical, or a small behavior: ≤3 adjacent files, one sitting, no unknowns Quick a red→green test + one commit
one behavior worth a written contract Task .add/tasks/<slug>.md + its commits
the answer IS the deliverable: investigate · evaluate · research Explore the task's ## FINDINGS
a theme, or more than one task Milestone .add/milestones/<slug>.md + its tasks

Floor: anything touching security · data · architecture, or a surface other code consumes, is at least a Task. When in doubt, size up.

Then follow the skill: Direction (rules · assumptions · failing checks, sealed by a freeze(<slug>) commit) → Build (to green, sealed files untouched) → Verify (seal intact · fresh green run · residue review · verdict in ## EVIDENCE, committed as verify(<slug>): <verdict>).

Rules that bind: the invariants: in PROJECT.md hold for every change, Quick included. Never weaken a sealed check or edit the contract to get green; changed intent is a visible refreeze(<slug>) commit. A security finding is a HARD-STOP verdict, flagged at the top of the report.

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.
