An add-on that gives an agent tools for understanding video, audio, and images and for searching, capturing, and monitoring online information. It organizes this work around an investigation case.

Use it to inspect media, gather open-source intelligence, capture online pages, and monitor sources as part of an investigation.

It brings media analysis and internet research into one case-based workflow. This helps keep collected material and observations connected while an investigation develops.

Security

Grade A, and why

overcast 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.

Changes

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.
