Token cost

What it costs to keep this loaded

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.

Security

Grade C, and why

claude-env CLAUDE.md scanned grade C with 1 finding 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.

Recursive force deletehighDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

What it actually says

claudenv

Shell environment switcher for Claude Code accounts.

Key constraints

  • install.sh must stay POSIX sh — no arrays, no select, no process substitution.
  • claudenv.sh targets bash 3.2+ and zsh 5+; arrays, select, and < <(...) are intentional.
  • No external dependencies. No build step.

GitHub Actions constraints

  • Do not pin actions to commit SHAs. Use semver tags (e.g. @v2, @v6). Dependabot keeps tags current.
  • Do not replace apt-installed tools with pinned binary downloads in Dockerfile.dev (e.g. shellcheck stays as apt-get install shellcheck).
  • Do not add update-type guards to dependabot-automerge.yml. All dependabot PRs are auto-merged, not just patch bumps.

Development constraints

  • a new branch and PR should be created per ralph-loop invocation, or any change set.

Testing

source claudenv.sh
claudenv config test-env
claudenv test-env          # prompt should show (test-env)
claudenv deactivate
rm -rf "$CLAUDENV_HOME/envs/test-env"

Test oh-my-zsh prompt integration by sourcing in an active zsh session with a theme loaded.

After you have created a PR, use the update-docs local claude skill.

Changes

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.
