SkillSpector: 2 findings, up to high
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 →

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00097 | $0.02312 |
| Opus 5 | $0.00048 | $0.01156 |
| Sonnet 5 | $0.00019 | $0.00462 |
| Haiku 4.5 | $0.00010 | $0.00231 |
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 2d 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 — 168 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Capture Usage4Claude Screenshots
Overview
Capture Usage4Claude popover screenshots by matching the user's manual CleanShot workflow: enter CleanShot window capture mode, hover the real mouse over the Usage4Claude popover, click, and rename the newly saved file in Downloads.
This workflow is fragile because CleanShot's window selector reacts to the real mouse position. Do not rely on app-relative Computer Use clicks for the final selection; use CoreGraphics to move the mouse to the window center and post a real click.
Preflight
Confirm these before capturing:
- Use the Debug Usage4Claude instance when the user requests it.
- Verify
Codexhas macOS Accessibility permission.Computer Usealone is not enough for shell-launchedosascript. - Verify this succeeds before starting CleanShot:
osascript -e 'tell application "System Events" to get count of application processes'
If it fails with not allowed assistive access or 不允许辅助访问, stop and ask the user to add Codex to System Settings > Privacy & Security > Accessibility.
Configure Usage4Claude
Set the screenshot state in Usage4Claude settings before capture.
- Claude-only: enable Claude 5-Hour, 7-Day, Extra Usage, 7D Opus, and 7D Sonnet; disable all Codex items.
- Codex-only: enable all 3 Codex limits; disable all Claude items.
- Mixed: enable Claude's first 3 limits and all 3 Codex limits.
- Switch language only inside Usage4Claude settings. Do not change language by writing
UserDefaultsor by external app-level language overrides. - Keep the Usage4Claude screenshot setting that prevents the popover from closing.
After changing settings, open the main Usage4Claude popover and inspect it with Computer Use. The screenshot should show the intended language and display items before CleanShot starts.
Reference Debug Usage Values
For canonical documentation screenshots, use a Debug build with Debug Mode enabled and set these eight slider values before capture:
| Debug slider | Value |
|---|---|
| Claude 5-Hour | 66% |
| Claude 7-Day | 88% |
| Claude Extra Usage | 66% |
| Claude Opus 7-Day | 66% |
| Claude Sonnet 7-Day | 66% |
| Codex Primary | 66% |
| Codex Secondary | 88% |
| Codex Extra Usage | 88% |
What ships with it
5 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.
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.

capture-usage4claude-screenshots is a skill published in the GitHub repository f-is-h/Usage4Claude (386 stars, last pushed 2d ago), licensed MIT. It adds 97 tokens to every session and 2,312 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
