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 | $0.00023 | $0.00611 |
| Opus 5 | $0.00012 | $0.00305 |
| Sonnet 5 | $0.00005 | $0.00122 |
| Haiku 4.5 | $0.00002 | $0.00061 |
Grade C, and why
pcl 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 2d 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.
rm -rf /tmp/spawn-worktrees 2>/dev/null || true How it starts
The opening of the file, as written. The whole thing — 108 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Cleanup Stale Branches
Delete local and remote git branches that no longer have an open PR, and prune stale worktrees.
Arguments
--dry-run— List what would be deleted without actually deleting anything.
$ARGUMENTS
Procedure
Step 1: Checkout main branch
Switch to main and update to latest:
git checkout main
git pull --rebase origin main
Critical: This ensures we're not on a branch that's about to be deleted, and that we're working from the latest main.
Step 2: Fetch and prune remote refs
git fetch --prune origin
Step 3: Identify stale remote branches
List all remote branches except main and HEAD:
git branch -r --format='%(refname:short) %(committerdate:relative)' | grep -v 'origin/main\|origin/HEAD\|^origin '
Step 4: Get branches with open PRs (protected)
gh pr list --repo OpenRouterLabs/spawn --state open --json headRefName --jq '.[].headRefName'
Any branch with an open PR MUST be skipped. Never delete a branch that has an open PR.
Step 5: Delete stale remote branches
For each remote branch that is NOT in the open PR list:
git push origin --delete BRANCH_NAME
If --dry-run was passed, print [dry-run] would delete origin/BRANCH_NAME instead.
Step 6: Delete stale local branches
List local branches (excluding the current branch and main):
git branch --list | grep -v '^\*' | grep -v '^ *main$' | tr -d ' '
For each, check if it's already merged into main or has no remote:
git branch -d BRANCH_NAME 2>/dev/null || git branch -D BRANCH_NAME
If --dry-run, print [dry-run] would delete local BRANCH_NAME instead.
Step 7: Prune worktrees
git worktree prune
Remove any leftover worktree directories:
rm -rf /tmp/spawn-worktrees 2>/dev/null || true
Step 8: Verify final state
Ensure we're on main branch:
git branch --show-current
Should output: main
Step 9: Summary
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.

pcl is a skill published in the GitHub repository OpenRouterLabs/spawn (233 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 23 tokens to every session and 611 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it C with 1 finding (recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
