Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.01446 | $0.01446 |
| Opus 5 | $0.00723 | $0.00723 |
| Sonnet 5 | $0.00289 | $0.00289 |
| Haiku 4.5 | $0.00145 | $0.00145 |
Grade A, and why
argue 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 2d 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.

Scope
This file applies to the whole argue repository.
Repo Overview
This repository is a monorepo with three workspace packages under unified versioning — root package.json holds the canonical version and every package carries the same number:
@onevcat/argue: reusable library (published)@onevcat/argue-cli: CLI host (published)@onevcat/argue-viewer: result viewer web app (private,private: true, never published)
The CLI depends on the library through a real semver dependency in packages/argue-cli/package.json. The viewer also consumes @onevcat/argue through a real semver range so its local build graph matches published reality.
Local Development
Use normal monorepo development flow for day-to-day work:
npm install
npm run dev
Useful commands:
npm run check: workspace typechecknpm run test: workspace testsnpm run build: workspace buildnpm run ci:check + test + buildnpm run smoke:pack: tarball install smoke tests for both packagesnpm run release:check:ci + smoke:packnpm run lint: ESLint across reponpm run format:check: Prettier validationnpm run format: format repo
Viewer-only shortcuts (for frontend iteration without rebuilding the library/CLI):
npm run dev:viewer: start the viewer Vite dev servernpm run build:viewer: build the viewer onlynpm run check:viewer: typecheck the viewer onlynpm run test:viewer: run the viewer test suite only
Recommended daily loop:
npm install- make code changes
npm run testnpm run release:checkbefore merging changes that affect packaging, dependency shape, or CLI installability
Package Development Rules
All workspace packages share one version. Do not bump packages individually — every release bumps root + every packages/*/package.json together and @onevcat/argue-cli / @onevcat/argue-viewer always depend on the exact same @onevcat/argue version.

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.

argue AGENTS.md is an instructions file published in the GitHub repository onevcat/argue (273 stars, last pushed 1mo ago), licensed MIT. It adds 1,446 tokens to every session, about $0.0072 per session on Opus 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.
