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 | $0.02665 | $0.02665 |
| Opus 5.5 | $0.01066 | $0.01066 |
| Sonnet 5.5 | $0.00533 | $0.00533 |
| Haiku 4.5 | $0.00266 | $0.00266 |
Grade A, and why
band-play 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 yesterday.
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 — 79 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Repository agents (Band Play)
This file orients human and AI contributors to the Band Play browser extension for Chrome and Firefox (Manifest V3). Prefer small, focused changes; do not refactor unless asked. Topic rules live in .claude/rules/.
Product
- Band Play (manifest
name"Bandcamp Play",short_name"BandPlay", npm packagebandcamp-play) — adds playback controls to Bandcamp: autoplay of the next track, loop track, seek step, playback speed and pitch correction, keyboard shortcuts and media keys, a highlight of visited albums and tracks, a feed player and batch download of purchases. - Pages (
https://bandcamp.com/*,https://*.bandcamp.com/*): album and track pages (/album/,/track/), Discover (/discover), the feed (/feed, with the React feed player), the collection and wishlist (bandcamp.com/<user>,bandcamp.com/<user>/wishlist). Batch download adds checkboxes and an overlay to the collection, wishlist and purchases pages. Other Bandcamp pages (an artist home page) get no page service and keep their keys. - Settings — edited in the toolbar popup (
options.html), stored inchrome.storage.local(notsync):autoplay,autoscroll,keepAwake(Chrome only),highlightVisited,playbackStep(1 to 120 seconds),loopTrack,showFeedPlayer,shortcuts,batchDownloadFormat,batchDownloadConcurrency(1 to 15),disabledShortcuts,mediaKeys,batchDownloadNotify,batchDownloadOpenPage,batchDownloadSkipDownloaded. The settings can be exported, imported and reset (configService) from the popup footer. - Downloads page —
downloads.html, opened as a tab by batch download: the queue with progress and per-item controls. - Build output —

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.
