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 | $0.11750 | $0.11750 |
| Opus 5.5 | $0.04700 | $0.04700 |
| Sonnet 5.5 | $0.02350 | $0.02350 |
| Haiku 4.5 | $0.01175 | $0.01175 |
Grade A, and why
yorishiro-proxy CLAUDE.md 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 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
- **Anything context-dependent belongs in no list.** `find`, `curl`, `gh api`, and How it starts
The opening of the file, as written. The whole thing — 581 lines — stays where its author put it; the contents beside it link to each section on GitHub.
yorishiro-proxy
A network proxy tool for AI agents — a MITM proxy for AI. Operates as an MCP (Model Context Protocol) server, providing traffic interception, recording, and replay capabilities for vulnerability assessment.
Status: OSS (Apache License 2.0) · Under active development
Architecture
Design: RFC-001 Envelope + Layered Connection Model. Implementation strategy: docs/rfc/envelope-implementation.md.
Principle: L7-first, L4-capable
- The default operation interface is a structured L7 view — Prioritize AI agent token efficiency by representing communication as structured data: method, URL, headers, body, etc.
- Raw bytes recording, viewing, and modification must be possible for all protocols — As a diagnostic tool, protocol-level anomaly detection and reproduction must be supported (pure transport-layer protocols like SOCKS5 apply to the tunneled protocol)
- L7 parsing is an overlay on top of raw bytes; the wire-observed raw bytes snapshot itself must not be destroyed or modified — Recorded raw bytes always reflect the original wire data; modifications must always be treated as separate derived data (e.g., modified variant)
Pipeline
TCP Listener (Layer 4)
→ Protocol Detection (peek bytes / ALPN)
→ Connection Stack (TCP → TLS → HTTP/1 | HTTP/2 → WS | gRPC | gRPC-Web | SSE | Raw)
→ Pipeline Steps
(HostScope → HTTPScope → Safety → PluginPre → Intercept → Transform → PluginPost → Record [→ UpgradeStep])
→ Flow Recording (L7 Message + L4 Envelope.Raw)
→ MCP Tool (Intercept / Replay / Search / Plugin Introspect)
Each connection is an explicit stack of Layers (RFC-001 §3.3); each Layer yields one or more Channels; the Pipeline runs on Envelopes drawn from those Channels. The data model is:
Envelope— protocol-agnostic outer container with identity (StreamID/FlowID/Sequence/Direction), provenance (Protocol), wire fidelity (Raw bytes), and a typedMessage.Message— protocol-specific payload (HTTPMessage,WSMessage,GRPCStartMessage/GRPCDataMessage/GRPCEndMessage,SSEMessage,RawMessage,TLSHandshakeMessage).
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.

yorishiro-proxy CLAUDE.md is an instructions file published in the GitHub repository usk6666/yorishiro-proxy (19 stars, last pushed yesterday), licensed Apache-2.0. It adds 11,750 tokens to every session, about $0.0470 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
