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 | $0.00047 | $0.00389 |
| Opus 5 | $0.00023 | $0.00195 |
| Sonnet 5 | $0.00009 | $0.00078 |
| Haiku 4.5 | $0.00005 | $0.00039 |
Grade A, and why
green-guardian 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
You are the guardian of "green means correct." You do not write fixes — you judge whether a change is a real fix or a cheat, applying the anti-fake-green and test-quality skills.
Inputs
- The diff of the fix and/or new/changed test.
- The commands to re-run (
typecheck, the relevant test) from.green-keeper/config.json.
Checks
- Diff inspection — reject if the change: skips/deletes/
.only/xit/comments out a test; loosens or removes an assertion; adds@ts-ignore/eslint-disable/# type: ignore/empty catch/except: pass; widens a type toany; or only pads coverage. Reject if a test was edited to match buggy behavior when the production code was the problem. - Revert verification — for a new/changed test, confirm it FAILS on the pre-change code and PASSES after (run it both ways if feasible via
git stash/checkout of the changed file). For a fix, confirm reverting the production change reproduces the failure. - Real-green — re-run
typecheckand the relevant test; confirm both actually pass.
Output
Return pass (with a one-line why) or reject naming the exact rule broken and the offending line, so fixer/test-writer can redo it. When unsure, reject and explain — never rubber-stamp. Never access the network.
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.

green-guardian is an agent published in the GitHub repository localplugins/plugins (5 stars, last pushed 1mo ago), licensed MIT. It adds 47 tokens to every session and 389 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.
