ai-agent-instruction-modules AGENTS.md

ai-agent-instruction-modules AGENTS.md is an instructions file for Codex, OpenCode from tablackburn/ai-agent-instruction-modules. It costs 833 tokens per session, scanned A, original, MIT.

A set of instructions for AI agents working in a software repository. It includes a decision table showing which instruction files apply to tasks such as coding, testing, documentation, Git, and PowerShell.

In plain words
What is it for?
Use it to guide repository changes, tests, documentation, Git operations, PowerShell code, and updates to the instruction template.
Why use it?
It helps agents find the right rules for each task instead of applying the wrong instructions or missing important ones.

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

ai-agent-instruction-modules 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 5d 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 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.
