AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is concrete, unconsented postinstall mutation of broad foreign AI-agent control surfaces, which meets the publish-block policy. The skip flags and lack of lifecycle networking do not restore consent.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
Installing the package through npm, including a local install for skill sync.
Impact
Unconsented alteration of Codex, Claude Code, Amp, Agents, and OpenCode instruction/control surfaces; global installs may persist a daemon.
Mechanism
postinstall copies package-owned skills into global AI-agent skill directories and may register daemon autostart
Policy narrative
Installation invokes a lifecycle script that defaults to global skill synchronization. It creates or refreshes opendevbrowser-managed skill packs in several unrelated AI-agent directories, including Codex and Claude Code, without an explicit user setup command. On qualifying global npm installs, the same postinstall flow can register daemon autostart persistence.
AI rationale
This is concrete, unconsented postinstall mutation of broad foreign AI-agent control surfaces, which meets the publish-block policy. The skip flags and lack of lifecycle networking do not restore consent.

Decision evidence
public snapshotAI identified this as a dangerous AI-agent capability at 99.0% confidence with low false-positive risk.
Evidence for policy risk
- package.json runs postinstall automatically.
- scripts/postinstall-sync-skills.mjs imports and invokes the packaged installer.
- dist/cli/installers/postinstall-skill-sync.js defaults lifecycle skill sync to global mode.
- dist/chunk-LF2V5NVJ.js copies bundled skills into ~/.codex/skills, ~/.claude/skills, ~/.amp/skills, ~/.agents/skills, and OpenCode.
- Global npm installs also reconcile a launch agent or scheduled task for the daemon.
Evidence against
- The lifecycle code has a repo-checkout and environment-variable skip.
- No external network endpoint is used by the postinstall skill-sync path.
