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

clean-gone 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 8d 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

Clean Gone Branches

Execute the following to clean up stale local branches deleted from the remote.

Steps

  1. List branches to identify [gone] status

    git branch -v
    

    Note: Branches with '+' prefix have worktrees that must be removed first.

  2. Identify worktrees for [gone] branches

    git worktree list
    
  3. Remove worktrees and delete [gone] branches

    git branch -v | grep '\[gone\]' | sed 's/^[+* ]//' | awk '{print $1}' | while read branch; do
      echo "Processing branch: $branch"
      worktree=$(git worktree list | grep "\\[$branch\\]" | awk '{print $1}')
      if [ ! -z "$worktree" ] && [ "$worktree" != "$(git rev-parse --show-toplevel)" ]; then
        echo "  Removing worktree: $worktree"
        git worktree remove --force "$worktree"
      fi
      echo "  Deleting branch: $branch"
      git branch -D "$branch"
    done
    

Expected Outcome

  • List all local branches with status
  • Remove worktrees for [gone] branches
  • Delete branches marked as [gone]
  • Report which worktrees and branches were removed

If no branches are marked as [gone], report that no cleanup was needed.

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.
