FluxDown is a free, open-source download manager built with Rust that handles web downloads, FTP, BitTorrent, eD2K, and HLS or DASH streams. It is for people who want resumable, browser-integrated downloads with a local desktop interface, and its built-in MCP server lets AI clients manage those downloads.

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 | $0.06117 | $0.06117 |
| Opus 5.5 | $0.02447 | $0.02447 |
| Sonnet 5.5 | $0.01223 | $0.01223 |
| Haiku 4.5 | $0.00612 | $0.00612 |
Grade A, and why
FluxDown 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 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 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.
