Security

Grade A, and why

fh-preprep 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.

  "description": "preprep — a presentation-preparation harness. 1 skill. One CLI over 17 lanes (7 built-in + 10 module) that reads a declared surface manifest and checks a talk's assets against each other: canonical-term ledger, jargon glosses, retired vocabulary, inter-slide dependencies, pacing, get/put round-trips, adjacent duplication, slide relations, geometry, attribute consistency, fonts, diagrams, slide refs, and screen-parity between manuscript and deck. Verdict contract: exit 0 pass / 1 findings / 2 cannot-judge — a surface that could not be read is UNMEASURED, never 0. Every lane ships a known-pair fixture. A separate advisory lane (lane_speech_coach.py) listens to a rehearsal recording and returns a six-item coaching table — pauses, conjunction drag, sentence-final pitch, opening/closing loudness, pronunciation candidates; ffmpeg required, whisper-cli optional, everything stays local.",

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.
