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 | $0.13747 | $0.13747 |
| Opus 5.5 | $0.05499 | $0.05499 |
| Sonnet 5.5 | $0.02749 | $0.02749 |
| Haiku 4.5 | $0.01375 | $0.01375 |
Grade A, and why
rnix CLAUDE.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.

Project Overview
Rnix is an operating system for AI agents, inspired by Unix design philosophy. It provides process management, a virtual filesystem (VFS), IPC via Unix domain sockets, multi-agent orchestration, intent decomposition, and debugging tools. Written in Go 1.26, module github.com/rnixai/rnix.

Build & Development Commands
每次会话的编码工作完成后，要运行一次 make all 检查是否有错误需要修复。
make build # Build binary → ./rnix
make test # Run all tests with race detection
make lint # golangci-lint
make vet # go vet
make all # lint + vet + test + build
make agtest # Tier1 agent-behavior regression suite, isolated daemon (PR gate; not part of `all`)
make agtest-live # Tier2 advisory suite against your ambient daemon + real provider/API key
# Run a single test
go test -race -run TestFunctionName ./package/...
# Run tests for a specific package
go test -race ./kernel/...
go test -race ./ipc/...
Prerequisite: Go 1.26+ (managed via mise.toml).
Architecture
Daemon Model
Rnix runs as a background daemon holding the kernel and process table. CLI commands communicate with the daemon over a Unix domain socket ($XDG_RUNTIME_DIR/rnix/rnix.sock or /tmp/rnix-$UID/rnix.sock). The CLI auto-starts the daemon via EnsureDaemon() if not running. Manage the daemon with rnix daemon status and rnix daemon stop.

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.

rnix CLAUDE.md is an instructions file published in the GitHub repository rnixai/rnix (6 stars, last pushed 3mo ago), licensed MIT. It adds 13,747 tokens to every session, about $0.0550 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 2026-08-31.
