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 | $0.00014 | $0.00295 |
| Opus 5.5 | $0.00006 | $0.00118 |
| Sonnet 5.5 | $0.00003 | $0.00059 |
| Haiku 4.5 | $0.00001 | $0.00030 |
Grade A, and why
stale-branches 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 yesterday.
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
Stale Branches
List local and remote git branches that are candidates for cleanup — merged but not deleted, and inactive branches with no recent commits.
Usage
/stale-branches [options]
Options
--threshold <months>- Inactivity threshold in months (default: 3)--base <branch>- Base branch for merge check (default: main)--remote- Include remote branch analysis
Examples
/stale-branches # Default: 3 months, main, local only
/stale-branches --threshold 1 # Stricter: 1 month inactivity
/stale-branches --remote # Include remote branches
/stale-branches --base develop # Use develop as base branch
/stale-branches --threshold 1 --remote # Combine flags
Implementation
Invoke the Skill tool with skill name "git:listing-stale-branches" and arguments: $ARGUMENTS
The skill will detect merged branches, inactive unmerged branches, and optionally analyze remote branches. It is read-only and never deletes branches.
For detailed documentation, see git/skills/listing-stale-branches/SKILL.md.
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.

stale-branches is a command published in the GitHub repository joaquimscosta/arkhe-claude-plugins (21 stars, last pushed yesterday), licensed MIT. It adds 14 tokens to every session and 295 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-10-16.
