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 | $0.00688 | $0.00688 |
| Opus 5.5 | $0.00275 | $0.00275 |
| Sonnet 5.5 | $0.00138 | $0.00138 |
| Haiku 4.5 | $0.00069 | $0.00069 |
Grade A, and why
nautex 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.

This file provides guidance to coding agents working in this repository.
What this project is
nautex-oss-util is the Nautex open-source gateway node and MCP tooling. It
hosts a single ACP-to-Nautex bridge (nautex gateway) plus the CLI and MCP
server used by coding agents to talk to the Nautex backend. The hot code
path is under src/nautex/gateway/.
Where to look
src/nautex/gateway/adapters/— one concrete adapter (ACPAgentAdapter) plus per-agent subclasses for Claude Code, OpenCode, Codex, and others. Seesrc/nautex/gateway/adapters/AGENTS.mdfor the per-agent compatibility matrix, credential sandboxing rules, and integration effort logs.src/nautex/gateway/adapters/launch_config.py— persistent config-file generation under~/.nautex/configs/with deterministic fingerprints.src/nautex/gateway/protocol/— synced withnt-backendviamake sync-agw-protocol. Edit here, then sync.scripts/— the session-config probe and legacy raw-ACP probes. Seescripts/AGENTS.mdfor the verification workflow (how and when to run the probe, how to read artifacts, when to add new scenarios).
Verification
The primary verification tool is the session-config probe. Full guide in
scripts/AGENTS.md. Quick reference:
| target | when | command |
|---|---|---|
| Session-config probe — single case | mid-iteration, fastest feedback | make session-config-probe ARGS='--agent X --scenario Y' |
| Session-config probe — full matrix | before opening a PR that touches adapters or protocol | make session-config-probe ARGS='--all --timeout 90' |
| ACP bridge + native binaries install check | after environment changes | make install-acp-adapters |
| Raw-ACP probe (new agent characterization only) | adding a new agent | python scripts/probe_acp_agents.py <agent_id> |
| Subsystem unit tests | when touching a specific subsystem | pytest tests/gateway/test_<subsystem>.py |
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.

nautex AGENTS.md is an instructions file published in the GitHub repository hmldns/nautex (87 stars, last pushed 2mo ago), licensed MIT. It adds 688 tokens to every session, about $0.0028 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.
