Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. LPM treats this as warn-only first-party agent extension lifecycle risk. Npm postinstall refreshes this package's own todoist-cli SKILL.md in coding-agent skill folders where that skill was already installed. First-time placement is the explicit td skill install command. This is first-party agent extension setup, not a new unconsented control-surface hijack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 86.0% - **Started:** 2026-09-19T02:10:13.539Z - **Finished:** 2026-09-19T02:14:18.651Z - **Download time:** 517 ms - **Static scan time:** 1086 ms - **AI review time:** 243508 ms - **Total time:** 245112 ms The recorded confidence comes from the underlying analysis.

First-time placement is the explicit td skill install command. This is first-party agent extension setup, not a new unconsented control-surface hijack. - **Trigger:** npm install runs postinstall; td skill install places the skill the first time. - **Impact:** After a CLI upgrade, already-installed agents may load an updated Todoist CLI skill without a separate skill-install step. - **Evidence paths:** package.json, dist/postinstall.js, dist/lib/skills/update-installed.js, dist/lib/skills/index.js, dist/lib/skills/create-installer.js, dist/commands/skill/install.js - **Review source:** ai\_review - **Reviewed:** 2026-09-19T02:14:18.651Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall rewrite of existing first-party agent skill files - **Rationale:** Postinstall only rewrites this package's todoist-cli skill in agent directories where it was already installed, which is first-party agent extension setup. Scanner malware and hijack labels are noisy: doctor.js is a local diagnostic, and there is no unconsented new agent install, secret theft, or remote payload. - **Files touched:** scripts/postinstall.js, dist/postinstall.js, ~/.claude/skills/todoist-cli/SKILL.md, ~/.codex/skills/todoist-cli/SKILL.md, ~/.copilot/skills/todoist-cli/SKILL.md, ~/.cursor/skills/todoist-cli/SKILL.md, ~/.gemini/config/skills/todoist-cli/SKILL.md, ~/.pi/agent/skills/todoist-cli/SKILL.md, ~/.agents/skills/todoist-cli/SKILL.md ### Review decision - **Verdict:** Suspicious - **Confidence:** 86.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** package.json postinstall runs scripts/postinstall.js on every npm install., Compiled postinstall silently refreshes already-installed agent skills and migrates legacy Todoist auth., Skill updater overwrites SKILL.md when the package skill or a legacy copy is already present., Installers target foreign agent directories .claude, .codex, .copilot, .cursor, .gemini, .pi, and .agents., update() creates the skill path and writes this package's todoist-cli SKILL.md., First placement is the explicit td skill install command, not a new unconsented seed. - **Evidence against:** No eval, child\_process, obfuscation, or runtime self-dependency., doctor.js is a user-invoked local diagnostic; the malware fingerprint is a scanner false positive., Network use is Todoist API traffic, including auth migration to api.todoist.com., Skill body is first-party Todoist CLI usage docs, not a remote skill channel., Postinstall does not install skills into agents that never received td skill install., Credentials are stored for Todoist and sent to the Todoist user API, not an unrelated host. ## Affected versions and remediation This report applies to @doist/todoist-cli@5.3.9. - Review the evidence and your use of @doist/todoist-cli@5.3.9 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
