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 | $0.03765 | $0.03765 |
| Opus 5.5 | $0.01506 | $0.01506 |
| Sonnet 5.5 | $0.00753 | $0.00753 |
| Haiku 4.5 | $0.00377 | $0.00377 |
Grade A, and why
streamkit 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 2mo 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 — 315 lines — stays where its author put it; the contents beside it link to each section on GitHub.
StreamKit Agent Notes
These notes apply to coding agents (Claude/Codex/Devin/etc.) contributing to this repo. Agent-assisted contributions are welcome, but should be supervised and reviewed by a human before merge.
What is StreamKit
StreamKit is a self-hostable media processing server (Rust). A single binary
(skit) runs pipelines as a node graph (DAG) — via a web UI, YAML, or
WebSocket API. Two modes: dynamic (real-time, hot-reconfigurable) and
oneshot (stateless batch processing). See agent_docs/architecture.md for
the full architecture.

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.

streamkit AGENTS.md is an instructions file published in the GitHub repository streamer45/streamkit (24 stars, last pushed 1mo ago), licensed MPL-2.0. It adds 3,765 tokens to every session, about $0.0151 per session on Opus 5.5. 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.
