Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00046 | $0.00363 |
| Opus 5 | $0.00023 | $0.00181 |
| Sonnet 5 | $0.00009 | $0.00073 |
| Haiku 4.5 | $0.00005 | $0.00036 |
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
-
List branches to identify [gone] status
git branch -vNote: Branches with '+' prefix have worktrees that must be removed first.
-
Identify worktrees for [gone] branches
git worktree list -
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.
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.

clean-gone is a skill published in the GitHub repository heyAyushh/stacc (3 stars, last pushed 2mo ago), licensed MIT. It adds 46 tokens to every session and 363 once invoked, about $0.0002 per session on Opus 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 2026-08-31.
