dsh-git-badge@0.16.0

Git status badges for DeepSeek Harness: an input-row chip on every install, plus sidebar session-row badges (git status, PR/CI action tokens) after one manual step: `npx dsh-git-badge apply`, then restart dsh web. Event-driven freshness over SSE.

AI Security Review

scanned 11d ago · by lpm-firewall-ai

LPM flags this version as an AI-agent control-surface risk. Installation automatically changes a separate DeepSeek Harness host package and adds a user-level agent skill. This is an unconsented lifecycle mutation of an AI-agent control surface.

Static reason

One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review

Trigger

npm installation runs the declared postinstall hook.

Impact

A package install can change agent commands and host UI code outside the installed package.

Mechanism

The hook installs the gh skill, patches the host client file, replaces its index file, and records a restart marker.

Policy narrative

The npm postinstall hook runs automatically. It installs a packaged skill into the user DSH skills directory, then, when its matching checks pass, overwrites files in the separately installed DSH host package and leaves a marker intended to activate the change after restart. The guarded patch and backups reduce accidental damage but do not establish consent for lifecycle-time changes to the host or agent command catalog.

AI rationale

This release performs automatic postinstall writes to a foreign AI-agent host and user-level skill catalog. That concrete control-surface mutation meets the blocking policy despite its stated UI purpose.
