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 A, and why

h5i 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.

What it actually says

CLAUDE.md

This workspace's debug build is very large

Large enough that it has filled a disk. The dependency graph carries a browser engine and a patched JavaScript engine, so target/debug runs to tens of gigabytes where target/release is a fraction of it.

That is a fact about the workspace and it applies to anyone who builds it. What follows from it depends on the machine, so it is not a repository rule: on a roomy box a dev build is ordinary, and CI builds one on purpose (.github/workflows/test.yaml runs on throwaway runners, so do not add --release there).

If your machine cannot spare the space, this repository ships two opt-in guards that make a release-only checkout stick:

  1. scripts/no-debug-guard.sh on writes a regular file at target/debug, so cargo stops with "failed to create directory ... File exists" before it compiles anything. off and status do what they say. The file lives under target/, which is ignored, so it never leaves your checkout.

  2. scripts/deny-debug-build.py is a Claude Code PreToolUse hook that refuses dev-profile cargo commands, target-directory redirection, and attempts to remove the guard. It is a script, not a setting: nothing wires it up until you add it to your own .claude/settings.local.json, which is gitignored.

    { "hooks": { "PreToolUse": [ { "matcher": "Bash", "hooks": [
      { "type": "command",
        "command": "python3 \"$CLAUDE_PROJECT_DIR/scripts/deny-debug-build.py\"" } ] } ] } }
    

With both on, every cargo invocation takes --release, the binary is ./target/release/h5i, and scripts that need it default to that path. Do not work around a "File exists" failure on target/debug: turn the guard off deliberately, or build release.

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.
