podkit: Instructions file for Codex

AGENTS.md

podkit AGENTS.md is an instructions file for Codex, OpenCode from jvgomg/podkit. It costs 6,727 tokens per session, scanned A, original, MIT.

Repository instructions for Podkit, a TypeScript toolkit that syncs music collections to iPod devices and is organized as a monorepo, meaning one repository containing multiple related packages.

In plain words
What is it for?
They are for developing and testing Podkit’s device support, music syncing, metadata, artwork, firmware, and documentation packages.
Why use it?
They give coding agents the project structure, development commands, and technical context needed to change the right package safely.

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions Claude Code; mentions AGENTS.md.

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

podkit 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 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.
