What is ai AGENTS.md?

Repository instructions for a collection of reusable OpenCode and Pi Coding Agent files, including agent profiles, prompts, skills, and Nix configuration. Nix is a tool for defining reproducible system and development setups.

Use them when editing the repository’s agent assets, Nix modules, or Pi TypeScript extensions, then run the specified validation commands.

They set rules for keeping changes focused and private, and list the checks needed to catch invalid Nix or TypeScript 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.

Model	Per session	Once invoked
Fable 5.1	$0.00222	$0.00222
Opus 5.5	$0.00089	$0.00089
Sonnet 5.5	$0.00044	$0.00044
Haiku 4.5	$0.00022	$0.00022

Security

Grade A, and why

ai 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

Repository Guide

This repository contains reusable OpenCode and Pi Coding Agent assets:

global-instructions.md for shared rules
agents/ for agent profiles
prompts/ for command prompts
skills/ for skill docs and helper scripts
nix/opencode.nix for the Home Manager OpenCode configuration module
nix/pi-coding-agent.nix for Pi Coding Agent Home Manager customizations

Working Principles

Keep changes small and focused.
Match existing style and conventions in nearby files.
Prefer self-documenting code over explanatory comments.
Do not add secrets, tokens, private URLs, or personal data.

Validation

For Nix module edits, validate flake/module syntax:

nix flake show --no-write-lock-file
nix-instantiate --parse ./nix/opencode.nix
nix-instantiate --parse ./nix/pi-coding-agent.nix

For Pi TypeScript extension edits, run:

npm run typecheck

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.
