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

usage-hud 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.

What it actually says

Usage HUD Skill

Configure the cap statusline display.

Quick Commands

Command Description
/cap:setup Install or repair HUD statusline
/cap:status Show HUD diagnostics
/cap:uninstall Completely remove CAP and restore previous settings

Customization

Edit the thresholds in scripts/usage-hud.mjs:

  • CACHE_TTL_MS: Usage API cache TTL (default: 60000ms). Increase to 120000 if hitting 429s.
  • Color thresholds: < 50% green, 50-69% yellow, 70-84% yellow bold, ≥ 85% red
  • Progress bar width: Change the width parameter in progressBar(pct, 10) calls

Troubleshooting

  • HUD not showing → Run /cap:setup, then restart Claude Code
  • Usage shows -- → Check OAuth token with /cap:status
  • Frequent [API 429] → Increase CACHE_TTL_MS to 120000 or higher
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.
