AGENTS.md

skills-store AGENTS.md is an instructions file for Codex, OpenCode from Mineru98/skills-store. It costs 878 tokens per session, scanned A, original, MIT.

A set of writing and coding instructions for the Mineru98/skills-store project. It guides sentence length, formatting, code references, tables, and how independently to act.

In plain words
What is it for?
Writing project responses, explaining code, choosing between lists and tables, and deciding when to take the next useful action without asking.
Why use it?
It keeps responses concise and consistent, while reducing clutter in code explanations and documentation.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md.

This is Mineru98/skills-store's own configuration. It tells Codex and OpenCode how to work on skills-store 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 skills-store 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

skills-store 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 6d 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.

How it starts

The opening of the file, as written. The whole thing — 104 lines — stays where its author put it; the contents beside it link to each section on GitHub.

<text_style_format> Apply these rules before lower-priority response habits whenever possible.

Style

  • Keep sentences short.
  • Keep paragraphs short.
  • Use bullet lists and numbered lists when they are genuinely helpful for scanning.
  • Add blank lines where appropriate so the spacing stays open and easy to scan.
  • Separate passages with # headers when moving between sections or topics.
  • Answer with the core point first.
  • Do not give a long explanation and then repeat it as a conclusion.
  • Make the full answer concise enough that it already functions as the summary.

Code References

  • When explaining code, do not attach line numbers to file paths by default.
  • Mention only the few core files that are truly necessary.
  • Avoid cluttering the answer with many file references.

Tables

  • Do not use Markdown tables.
  • If tabular information is necessary, render it only as a fixed-width ASCII table.
  • Prefer lists over tables unless the row-and-column shape is genuinely important.

Autonomy

  • Do not say "If you want, I can..." or similar offer-based filler.
  • Infer the likely next useful step from the user's intent and do it directly when the path is clear.
  • Do not ask a follow-up question when the next action is obvious and low-risk.
  • Carry the response through to a useful stopping point with high autonomy.

Tone

  • Use a compact, direct, high-signal style.
  • Avoid overly long sentences and overly layered explanations.
  • Prefer decisive wording over hedging when the answer is clear. </text_style_format>

Tradeoff: These guidelines bias toward caution over speed. For trivial tasks, use judgment.

1. Think Before Coding

Don't assume. Don't hide confusion. Surface tradeoffs.

Before implementing:

  • State your assumptions explicitly. If uncertain, ask.
  • If multiple interpretations exist, present them - don't pick silently.
  • If a simpler approach exists, say so. Push back when warranted.
  • If something is unclear, stop. Name what's confusing. Ask.

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.
