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. Install-time code rewrites already-installed Todoist skill files in several coding-agent directories. No confirmed exfiltration or remote-code-execution attack was identified. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-09-22T12:10:42.732Z - **Finished:** 2026-09-22T12:11:54.199Z - **Download time:** 1518 ms - **Static scan time:** 1257 ms - **AI review time:** 68691 ms - **Total time:** 71467 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:** Install-time code rewrites already-installed Todoist skill files in several coding-agent directories. No confirmed exfiltration or remote-code-execution attack was identified. - **Trigger:** npm postinstall runs after installation. - **Impact:** Existing agent skill instructions can change automatically when this package is installed or updated. - **Evidence paths:** dist/postinstall.js, dist/lib/skills/update-installed.js, dist/lib/skills/create-installer.js, dist/lib/skills/index.js - **Review source:** ai\_review - **Reviewed:** 2026-09-22T12:11:54.199Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The postinstall entry calls the installed-skill updater, which checks for an existing skill and rewrites its SKILL.md content. - **Rationale:** Automatic postinstall mutation of existing coding-agent skill files is a concrete guarded agent-extension lifecycle risk. The code is scoped to detected Todoist skill files, so a warning rather than a block is appropriate. - **Files touched:** dist/postinstall.js, dist/lib/skills/update-installed.js, dist/lib/skills/create-installer.js, dist/lib/skills/index.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package declares an automatic postinstall hook., The hook updates detected installed agent skills during package installation., Skill updates rewrite skill files after checking whether they already exist., The installer targets multiple coding-agent skill directories, including .claude and .codex., The doctor network check is registered as an explicit doctor command with an offline option. - **Evidence against:** The skill update path is gated on an existing installed or legacy skill; it does not create every agent integration unconditionally., No evidence of arbitrary command execution, remote payload loading, or credential exfiltration was found in the inspected paths. ## Affected versions and remediation This report applies to @doist/todoist-cli@5.3.12. - Review the evidence and your use of @doist/todoist-cli@5.3.12 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.
