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 | $0.01878 | $0.01878 |
| Opus 5.5 | $0.00751 | $0.00751 |
| Sonnet 5.5 | $0.00376 | $0.00376 |
| Haiku 4.5 | $0.00188 | $0.00188 |
Grade A, and why
personal-os-setup CLAUDE.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 today.
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.

CLAUDE.md
@AGENTS.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository. The canonical cross-agent rules are imported from AGENTS.md above; this file adds Claude Code-specific depth.
Hard rule — approved per action, every time: never run git commit and never run git push without the user's explicit approval. A task description, a plan, "do the work", or a previous approval is not permission. Ask, wait for the yes, then run exactly what was approved (this includes --force, PR creation/merge, and release-branch actions). If an approval prompt times out, stop — silence is not consent.
Architecture
OS/distro detection → package catalog → UI
detect_os.py is the entry point for environment awareness:
detect_os()returns anOSInfo(family, distro, info)— family iswindows/darwin/linux/unknown; on Linux,distrocomes from/etc/os-releaseID(e.g.ubuntu,cachyos), and WSL is detected separately (_is_wsl(), checks/proc/sys/fs/binfmt_misc/WSLInteropor/proc/version).build_packages_for_os()loadssrc/personal_os_setup/config/packages.yaml(the single source of truth for installable packages, keyed by distro → manager → category → package list) and filters it to the current distro viaPackageCatalog.for_distro(), producing a flat list ofPackageRef(name, manager, category).
Package managers (tasks/managers/)
Each backend (apt, snap, brew/cask, winget, msstore, pacman/paru, webinstall) implements the PackageManager protocol in tasks/managers/base.py: is_installed, install, update, upgrade, cleanup. tasks/factory.py maps (distro, manager_name) → manager class in _PACKAGE_MANAGER_FACTORY_BY_DISTRO, and _UI_VISIBLE_MANAGERS_BY_DISTRO controls which managers are surfaced in the UI per distro (e.g. only apt shown for Ubuntu even though snap/webinstall also exist) to avoid duplicate buttons.
tasks/managers/_shared.py centralizes result-construction boilerplate reused across backends: command_details()/format_failed_command() (stdout/stderr → details text), sudo_required_task_result()/sudo_required_install_result(), missing_executable_task_result()/missing_executable_install_result(), and winget_path()/winget_list_shows_installed() (shared by the winget and msstore backends). Each manager still calls shutil.which(...)/sudo_non_interactive_ok() itself (not through _shared.py) so unit tests can keep patching those checks at the manager's own module path — _shared.py only builds the resulting TaskResult/InstallResult once the check has failed. Follow this pattern (local check, shared result-builder) when adding a new manager rather than re-deriving the boilerplate.
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.

personal-os-setup CLAUDE.md is an instructions file published in the GitHub repository AmineDjeghri/personal-os-setup (662 stars, last pushed today), licensed MIT. It adds 1,878 tokens to every session, about $0.0075 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.
