For global npm installs it can also create daemon autostart persistence. - **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. - **Evidence paths:** package.json, scripts/postinstall-sync-skills.mjs, dist/cli/installers/postinstall-skill-sync.js, dist/chunk-LF2V5NVJ.js, dist/chunk-N3DMWGVF.js, dist/chunk-VW5VSUEN.js - **Review source:** ai\_review - **Reviewed:** 2026-08-04T10:16:46.995Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall copies package-owned skills into global AI-agent skill directories and may register daemon autostart - **Attack 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. - **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. - **Files touched:** scripts/postinstall-sync-skills.mjs, dist/cli/installers/postinstall-skill-sync.js, dist/chunk-LF2V5NVJ.js, ~/.codex/skills, ~/.claude/skills, ~/.amp/skills, ~/.agents/skills, ~/.config/opencode/skill ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** 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. ## Public findings ### 1.
