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 | $0.00025 | $0.00307 |
| Opus 5 | $0.00013 | $0.00153 |
| Sonnet 5 | $0.00005 | $0.00061 |
| Haiku 4.5 | $0.00003 | $0.00031 |
Grade A, and why
plumber-review 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 10d 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
Review code changes for patchwork only, not correctness. One line per finding.
Format
L<line>: <tag> <what is patched>. <redesign>.
Tags:
patch:fix covering a design flaw. Name the flaw.complexity:code added to fight existing complexity. Name the root.phantom:error handling for a scenario that shouldn't exist.shrink:same logic, genuinely simpler structure. Show the simpler form.
Examples
✅ L22-45: patch: null guard hiding upstream caller passing wrong type. Fix the caller.
✅ L8: phantom: try/catch around code that can't throw. Remove.
✅ L31-60: complexity: retry logic working around a non-idempotent API. Make the API idempotent.
✅ L14-28: shrink: manual recursion reimplementing reduce. sum(items), 1 line.
Scoring
End with: root causes addressable: <N>.
If nothing to fix: Clean pipes. Ship.
Boundaries
Scope: patchwork and complexity only. Correctness bugs and security are out of scope. Lists findings, applies nothing. One-shot.
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.

plumber-review is a skill published in the GitHub repository akshatnerella/plumber (8 stars, last pushed 2mo ago), licensed MIT. It adds 25 tokens to every session and 307 once invoked, about $0.0001 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.
