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 | $0.00000 | $0.00402 |
| Opus 5.5 | $0.00000 | $0.00161 |
| Sonnet 5.5 | $0.00000 | $0.00080 |
| Haiku 4.5 | $0.00000 | $0.00040 |
Grade A, and why
setup 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 1mo 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.
What it actually says
PM Brain setup
The user invoked /setup to prepare the Python environment for this repo.
Python virtual environment
This repo expects a local virtualenv at .venv/ (ignored by git).
-
If
.venv/is missing: create it from the project root, then upgrade pip and install dependencies (needs network for pip):python3 -m venv .venv .venv/bin/python3 -m pip install --upgrade pip .venv/bin/pip install -r requirements.txtOn Windows, use
.venv\Scripts\pythoninstead of.venv/bin/python3, and.venv\Scripts\pipinstead of.venv/bin/pip. -
If
.venv/already exists: optionally run.venv/bin/python3 -m pip install --upgrade pip, then.venv/bin/pip install -r requirements.txtso pip and dependencies match currentrequirements.txt(user may skip if they prefer not to upgrade). -
Activate for this session when you open a shell in the repo:
source .venv/bin/activate(Windows:.venv\Scripts\activate). -
On project open:
.vscode/settings.jsonsetspython.defaultInterpreterPathto.venvandpython.terminal.activateEnvironmentso new integrated terminals auto-activate that env when the Python extension is active.
If python3 or venv creation fails, tell the user what broke and what to install (e.g. Python 3 from python.org or their OS package manager).
Done: confirm .venv exists, pip was upgraded (or note if skipped), dependencies are installed (or note what was skipped), and the env is active for any follow-up commands you run.
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.

setup is a command published in the GitHub repository ertra/pm-brain-for-cursor (22 stars, last pushed 5mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 402 tokens. 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.
