puer: Instructions file for Codex

AGENTS.md

puer AGENTS.md is an instructions file for Codex, OpenCode from startsevdev/puer. It costs 95 tokens per session, scanned A, original, MIT.

A project instruction file for the puer repository. It tells coding agents to read the project’s memory index before working and to save lasting knowledge in the memory directory.

In plain words
What is it for?
It is for guiding agent work on puer and maintaining its project memory.
Why use it?
It gives the agent access to decisions and facts from earlier work instead of starting with no project history. Keeping one fact per file also makes that knowledge easier to update.

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

puer 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 1mo 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.

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.
