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. Installation automatically refreshes previously installed Todoist skills in foreign agent configuration directories. It also performs a best-effort migration using existing Todoist authentication state. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 86.0% - **Started:** 2026-09-03T17:55:09.007Z - **Finished:** 2026-09-03T17:56:15.165Z - **Download time:** 1012 ms - **Static scan time:** 1933 ms - **AI review time:** 63212 ms - **Total time:** 66158 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Installation automatically refreshes previously installed Todoist skills in foreign agent configuration directories. It also performs a best-effort migration using existing Todoist authentication state. - **Trigger:** npm installation or upgrade runs postinstall. - **Impact:** Previously installed agent instructions can change without an explicit skill-update command; a legacy Todoist token is sent to the Todoist API only for migration. - **Evidence paths:** package.json, dist/postinstall.js, dist/lib/skills/update-installed.js, dist/lib/skills/create-installer.js, dist/lib/skills/index.js, dist/lib/migrate-auth.js - **Review source:** ai\_review - **Reviewed:** 2026-09-03T17:56:15.165Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Lifecycle-driven agent skill rewrite and legacy authentication migration. - **Rationale:** The package has a real automatic agent-extension lifecycle surface, so it warrants a warning. Static inspection shows a constrained first-party skill updater and Todoist-aligned migration rather than a concrete malicious chain. - **Files touched:** 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 - **Network endpoints:** api.todoist.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 86.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** Its npm postinstall automatically loads package code., Postinstall rewrites every previously installed Todoist agent skill., The updater writes files into multiple agent configuration directories., Postinstall also uses a saved legacy token to call the Todoist API during migration. - **Evidence against:** Skill updates occur only when that specific Todoist skill already exists., The mutation is limited to this package's SKILL.md and known agent directories., No self-dependency, remote code loading, shell execution, or non-Todoist exfiltration was found. ## Affected versions and remediation This report applies to @doist/todoist-cli@5.2.0. - Review the evidence and your use of @doist/todoist-cli@5.2.0 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.
