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 | $0.03274 | $0.03274 |
| Opus 5.5 | $0.01310 | $0.01310 |
| Sonnet 5.5 | $0.00655 | $0.00655 |
| Haiku 4.5 | $0.00327 | $0.00327 |
Grade A, and why
ag2-assistant 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 12d 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.
How it starts
The opening of the file, as written. The whole thing — 240 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AG2 Assistant — Development Guidelines
AG2 Assistant (package ag2-assistant) is an open-source personal AI assistant
built on AG2's framework.
This file is the contributor guide for humans and AI coding agents alike. For a
product overview see README.md; for the system design see
docs/architecture.md.
AI-assisted contribution policy
We welcome AI-assisted contributions — but you remain responsible for
everything you submit: code, tests, issues, and PR descriptions. Before
opening a PR, read .github/AI_POLICY.md. In short:
understand and test what you submit, make the PR description reflect the real
diff, and be ready to explain the change in your own words. Fill in
.github/PULL_REQUEST_TEMPLATE.md and only
tick a checklist box once it is actually true.
Development setup
python -m venv .venv
source .venv/bin/activate
pip install -e ".[dev]" # add ",google" for the Gmail/Calendar/Drive extra
pre-commit install # run the lint/format/safety hooks on every commit
Checks (run these before you push)
These are the same checks CI runs. They are advisory: the repository has no rulesets, so
a red pull request is reported by the CI status check rather than blocked by it. (Classic
branch protection needs admin to read, so it has not been ruled out. To enforce this,
require the single CI status check — it stays one name as the test matrix grows.)
ruff check . # lint
ruff format . # auto-format (use --check to verify only)
mypy # typecheck src/assistant (target is configured; pass no path)
pytest -m "not integration" -q # unit tests — no API key needed
npm --prefix web run check # typecheck the SPA (svelte-check, strict)
npm --prefix web test # SPA unit tests (node:test over web/src/**/*.test.ts)
npm --prefix web run build # rebuild the SPA bundle if you touched web/
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.
