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.

rpg-gamemaster 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 20d 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
{
"name": "rpg-gamemaster",
"description": "Session prep and run layer for dark-leaning Pathfinder 2e campaigns — runs a session zero that builds the player characters and anchors them to the world, then turns built worlds into runnable sessions, advances the world between sessions with fronts and progress clocks, builds balanced PF2e encounters and non-combat challenges (social/chase/research/infiltration via the Victory Points subsystem), itemizes treasure from the official Treasure-by-Level budget and tracks wealth, produces a tool-agnostic GM run sheet, and closes the loop after a session with a recap that reconciles the GM's account against the vault — updating session outcomes, quest status, and clue reveals, and asking the GM to adjudicate any divergence. Reads the campaign vault and clue map; persists player characters, sessions, fronts, clocks, encounters, challenges, events, and items through the rpg-preserve write gate.",

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.
