Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

PostToolUse 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 8d ago.
A static scan of the commands this hook runs, not an audit. A hook is shell that executes on your machine at the event it names, which is why every command in it is printed with what was found.
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.

Matched on the fetch tool and on Bash, because the usual way a review arrives is a workflow committing it and the user pulling. It compares the review on disk against the version ponytail last saw rather than trying to catch the write, so it is right however the file got there. FORGE_NO_REVIEW_TRIGGER=1 turns it off."

After the write rather than before, because the reference cannot be checked until it exists. Never blocks, never fixes: it hands the question to the user, because a silent correction is a second guess stacked on the first. FORGE_NO_GROUNDING=1 turns it off."

This page is one entry in a file that holds 4. Installing the file brings all of them; each is measured and scanned on its own page.
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.

PostToolUse is a hook published in the GitHub repository Hassaan146/forge-mentor (22 stars, last pushed 22d ago), licensed MIT. Its token cost is not measured: a hook is shell that never enters the context. 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.
