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.
/plugin marketplace add SWHee/diffscopenpx agentmods add plugins/swhee/diffscope/diffscopegit clone --depth 1 https://github.com/SWHee/diffscopeGrade A, and why
diffscope 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 ships with it
1 file beside plugin.json in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

diffscope is a plugin published in the GitHub repository SWHee/diffscope (1 stars, last pushed 29d ago), licensed MIT. Its token cost is not measured: this kind of file is read by the harness, not the model. 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.

hush
Trims command output, logs, and Claude's play-by-play before they pile up in the session, so long, noisy work stays quiet and readable. Install and forget — nothing to configure. Short questions with nothing to run cost a little more.
claude-code-message-timestamps
Shows the local time on every message and tells Claude when each prompt was sent — so you can scan a conversation, see how long things took, and reference earlier blocks.
