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.
npx agentmods add commands/owainlewis/youtube-tutorials/cleanupgit clone --depth 1 https://github.com/owainlewis/youtube-tutorialsWhat 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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00000 | $0.00181 |
| Opus 5 | $0.00000 | $0.00090 |
| Sonnet 5 | $0.00000 | $0.00036 |
| Haiku 4.5 | $0.00000 | $0.00018 |
Grade A, and why
cleanup 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 3d 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
Cleanup
Clean up local branches and stale references.
Instructions
- Fetch and prune remote references:
git fetch --prune - List all local branches:
git branch - Identify branches that have been merged into main
- Show the list and confirm before deleting anything
- Delete confirmed branches:
git branch -d <branch>
Rules
- Only delete branches that have been fully merged
- Use
-d(safe delete), never-D(force delete) unless explicitly asked - Never delete
mainordevelop - Show the full list of branches to delete and get confirmation first
- Report how many branches were cleaned up
Also check
git stash list— remind the user if they have stashed work- Any branches with unpushed commits — warn before suggesting deletion
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.

cleanup is a command published in the GitHub repository owainlewis/youtube-tutorials (375 stars, last pushed 11d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 181 tokens. 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 2026-08-30.
