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 agent skill files in several assistant home directories when a copy is already installed, and it can write a universal .agents skill without the usual directory check on an explicit install.

The auth migration calls only the Todoist user API. - **Trigger:** npm postinstall, and an explicit skill install command for the .agents installer. - **Impact:** Previously installed assistant skills for this CLI are replaced on package install. A universal .agents skill can be created by the install command without the presence check used for other agents. No secret export or remote code execution was found. - **Evidence paths:** package.json, scripts/postinstall.js, dist/postinstall.js, dist/lib/skills/update-installed.js, dist/lib/skills/index.js, dist/lib/skills/create-installer.js - **Review source:** ai\_review - **Reviewed:** 2026-09-27T23:33:25.427Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** updateAllInstalledSkills walks the bundled installers and overwrites an existing SKILL.md under the matching home directory. install() writes that file and, for .agents, does not require the agent directory to exist first. - **Rationale:** Install-time code rewrites this package's skill files inside foreign assistant config directories, which is first-party agent-extension lifecycle behavior and should be warned. Updates are limited to skills already present, and the only credential send is a bearer call to the Todoist user API. - **Files touched:** .claude, .codex, .copilot, .cursor, .gemini, .gemini/config, .pi, .pi/agent, .agents - **Network endpoints:** https://api.todoist.com/api/v1/user ### Review decision - **Verdict:** Suspicious - **Confidence:** 81.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** package.json registers a postinstall script that runs scripts/postinstall.js., dist/postinstall.js calls updateAllInstalledSkills(false) and migrateLegacyAuth during install., updateAllInstalledSkills rewrites a skill when that agent skill or a legacy copy is already present., skillInstallers target Claude Code under .claude and also Codex, Copilot, Cursor, Gemini, Pi, and a universal .agents directory., createInstaller install and update create the skill directory and write a generated SKILL.md., Global install skips the agent-directory existence check when dirName is .agents. - **Evidence against:** The postinstall updater skips agents that do not already have this package skill or a legacy copy., The generated skill is Todoist CLI usage text for the td command, not a downloaded payload., Legacy auth migration sends the stored token only to https://api.todoist.com/api/v1/user., Other global installers refuse to create a skill when the agent home directory is missing. ## Affected versions and remediation This report applies to @doist/todoist-cli@5.4.1. - Review the evidence and your use of @doist/todoist-cli@5.4.1 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.
