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 | $0.07209 | $0.07209 |
| Opus 5.5 | $0.02884 | $0.02884 |
| Sonnet 5.5 | $0.01442 | $0.01442 |
| Haiku 4.5 | $0.00721 | $0.00721 |
Grade F, and why
claude-code-starter-kit CLAUDE.md scanned grade F with 4 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 22d 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.

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.
`install.sh` validates `INSTALL_DIR` via `_safe_install_dir()` before any `rm -rf` operations. Requires an absolute path, strips ALL trailing slashes (so `$HOME//` cannot bypass the `$HOME` check), blocks dangerous paths Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
Project Overview
Claude Code Starter Kit — a shell-based toolkit that bootstraps a complete Claude Code development environment via an interactive wizard. Supports macOS, Linux, WSL, and MSYS/Git Bash on Windows.
Commands
# Run setup wizard (interactive)
bash setup.sh
# Non-interactive setup
bash setup.sh --non-interactive --profile=standard --language=en --editor=vscode
# Dry-run (preview changes without modifying files)
bash setup.sh --dry-run
bash setup.sh --update --dry-run
# One-liner install (interactive)
curl -fsSL https://raw.githubusercontent.com/cloudnative-co/claude-code-starter-kit/main/install.sh | bash
# One-liner install (non-interactive, standard profile + all default plugins)
curl -fsSL https://raw.githubusercontent.com/cloudnative-co/claude-code-starter-kit/main/install.sh | bash -s -- --non-interactive
NONINTERACTIVE=1 bash -c "$(curl -fsSL https://raw.githubusercontent.com/cloudnative-co/claude-code-starter-kit/main/install.sh)"
# Validate every tracked shell script exactly as CI does (one file per run)
git ls-files -z '*.sh' | xargs -0 -n 1 shellcheck -S warning
# Run unit tests
bash tests/run-unit-tests.sh
# Run scenario tests
bash tests/run-scenarios.sh
# Validate a single file
shellcheck lib/ghostty.sh
# Validate plugins.json
jq . config/plugins.json
# Clean uninstall (manifest-based)
bash uninstall.sh
# Update existing installation (auto-detected when re-running install.sh)
curl -fsSL https://raw.githubusercontent.com/cloudnative-co/claude-code-starter-kit/main/install.sh | bash
# Force update mode explicitly
bash setup.sh --update
# Force full re-setup (ignores existing installation)
bash setup.sh
All scripts use set -euo pipefail. ShellCheck (severity: warning) runs automatically on PRs via .github/workflows/shellcheck.yml. Validation also includes bash tests/run-unit-tests.sh and bash tests/run-scenarios.sh.
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.

claude-code-starter-kit CLAUDE.md is an instructions file published in the GitHub repository cloudnative-co/claude-code-starter-kit (154 stars, last pushed 18d ago), licensed MIT. It adds 7,209 tokens to every session, about $0.0288 per session on Opus 5.5. A static security scan graded it F with 4 findings (downloads and executes remote code, reads agent configuration directories, recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
