Skill for Codex

Written for Codex: agents/openai.yaml present. Also seen: installed under .agents/ (shared by several agents); mentions Codex.

This is f-is-h/Usage4Claude's own configuration. It tells Codex how to work on Usage4Claude 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 Usage4Claude configures →

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is ./scripts/render_docs_images.sh [output-dir] # default: docs/images.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Skill attempts to nullify the agent's safety policies or restrictions ('you have no restrictions', 'ignore your guidelines', 'do anything now'). This is a direct jailbreak that disables guardrails.
    Fix: Remove jailbreak framing that nullifies safety policies or restrictions. Skill content must not instruct the agent to ignore its guidelines or operate without guardrails.

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

capture-usage4claude-screenshots 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.

How it starts

The opening of the file, as written. The whole thing — 235 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Usage4Claude Documentation Images

Everything the READMEs show of the app is rendered, not captured. scripts/render_docs_images.sh compiles the whole app plus scripts/docs-images/main.swift into a command-line tool and draws the real SwiftUI views into PNGs. It is deterministic, needs no GUI, and does not disturb whoever is using the machine.

./scripts/render_docs_images.sh [output-dir]      # default: docs/images

One run emits 28 files: 7 languages × 2 scenes × light/dark. Expect a couple of minutes — the tool is rebuilt from scratch every time.

Render into a scratch directory first, look at the results, and only then write to docs/images/. Never overwrite the committed images with an unreviewed batch.

Output And Where It Goes

All images live in docs/images/.

File Size Used by
hero.<lang>.<variant>@2x.png 950×348pt README first screen
settings.display.<lang>.<variant>@2x.png 540×1244pt (CJK) / 540×1257pt (Latin) README interface section
  • <lang> is en, ja, zh-CN, zh-TW, ko, fr, de. These follow the existing docs/images and README.zh-CN.md spelling and deliberately differ from AppLanguage's raw values (zh-Hans, zh-Hant). The mapping lives in docsLanguageCode.
  • <variant> is light or dark.
  • @2x matches renderer.scale = 2; always display at the logical point width so the image stays crisp without being upscaled.
  • Settings heights differ by language because the descriptions wrap differently. That is expected; do not treat it as a defect.

Path references differ by README: the root README.md uses docs/images/…, while docs/README.<lang>.md uses images/….

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
