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 | $0.03956 | $0.03956 |
| Opus 5.5 | $0.01582 | $0.01582 |
| Sonnet 5.5 | $0.00791 | $0.00791 |
| Haiku 4.5 | $0.00396 | $0.00396 |
Grade A, and why
argus 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 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.
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 — 279 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Argus — Agent Guide
This file is the short version of the README, aimed at an agent using Argus through MCP. Argus is a QA capability inside the host's current task; it does not replace the host agent's identity or authority.
Setup
Use Python 3.11 or newer. With an older default interpreter, launch with
uvx --python 3.12 --from argus-testing argus-mcp.
# Web mode (works everywhere)
pip install argus-testing
playwright install chromium
# Screen mode (macOS only — to test native apps + browser chrome)
pip install 'argus-testing[mac]'
brew install cliclick
# Wire it into the MCP host
claude mcp add argus -- argus-mcp
argus-mcp --version # confirm host loaded the version you expect
argus-mcp --list-tools # show the selected profile and public tools
argus-mcp --doctor # Chromium, report dir; on macOS also screen grants
The default web profile has 29 tools covering the complete testing loop,
including regression_check. For structured-result-aware hosts, add
--response-mode compact. Earlier agent and core names select web.
--response-mode delta is opt-in for snapshot-aware clients. Only observation
fields listed in the protocol may be inherited from an exact base_id; action
and verification results are current-call-only. If context or a base is missing,
call observe for full state. Never infer a passing check from unchanged fields.
Use python -m argus.install_check to verify installed versions and stdio without
a browser or model. From a source checkout, python -m argus_lab.evaluation.overhead
gives deterministic byte measurements. Bytes are not model tokens. Monitoring retains numeric
overhead only; do not add page content or arguments to metrics.
Use --tool-profile screen for native
macOS review and --tool-profile advanced only when network mocks,
cookies/storage, tabs, coordinates, crawling or link/performance probes are
needed. full adds every screen tool as well. The
ARGUS_TOOL_PROFILE environment variable provides the same setting.
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.

argus AGENTS.md is an instructions file published in the GitHub repository chriswu727/argus (4 stars, last pushed yesterday), licensed MIT. It adds 3,956 tokens to every session, about $0.0158 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.
