inspectrum

A plugin that automatically sends plans to Codex for a limited review before Claude Code approval. Claude Code is a coding assistant that can inspect and change software projects.

In plain words
What is it for?
Use it for automatic plan-mode checks in Claude Code or for manually reviewing plans with the plugin's review command and hooks.
Why use it?
It adds a review step before approval while leaving the final decision with you, which can expose issues in a plan before work starts.

Security

Grade A, and why

inspectrum 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.

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.
