Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00148 | $0.01276 |
| Opus 5 | $0.00074 | $0.00638 |
| Sonnet 5 | $0.00030 | $0.00255 |
| Haiku 4.5 | $0.00015 | $0.00128 |
Grade A, and why
manage-apps-and-sounds-headless scanned grade A with 1 finding 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 7d 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.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
- Network: prefix `op`/HTTP with `env -u *PROXY*` (and curl `--noproxy '*'`) to bypass the sandbox proxy. How it starts
The opening of the file, as written. The whole thing — 73 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Self-Evolving Skill: This skill improves through use. If instructions are wrong, parameters drifted, or a workaround was needed — fix this file immediately, don't defer. Only update for real, reproducible issues.
Headless dashboard automation via pushover_headless_web_control.ts (function/enum-driven Bun
TypeScript — run directly, no build; needs bun install in skills/_lib/ for playwright-core).
pushover.net login is a plain email/password form (no anti-bot / CAPTCHA / 2FA — verified
2026-05-30), so plain Playwright + system Chrome works.

Custom sounds: constraints + sourcing pipeline (verified 2026-05-30)
Pushover custom sounds: MP3 only, < 500 KB, ≤ 30 s (iOS won't play longer). Sweet spot for "loud + as long as possible": ~29 s at 128 kbps ≈ 454 KB. Two helpers automate sourcing/processing:
# 1) discover free MP3 jingles (Mixkit free license, attribution optional)
bash "$(cc-plugin-root pushover-commander)/skills/_lib/find_jingles.sh" win # or game musical alarm celebration
bash "$(cc-plugin-root pushover-commander)/skills/_lib/find_jingles.sh" tag/happy # stock-music tags (longer tracks)
# 2) trim + LOUDNESS-NORMALIZE + size-fit to a compliant sound (loudnorm I=-10, peak -1dB, <500KB)
bash "$(cc-plugin-root pushover-commander)/skills/_lib/make_custom_sound.sh" <url|file> out.mp3 [start_s] [dur] [bitrate]
# -> JSON {kb, dur, max_db, mean_db, under_500kb}; non-zero exit if >=500KB (then lower bitrate)
# 3) upload it
WEB add-sound --name my_jingle --file out.mp3 --desc "loud 29s jingle"
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.
