## Verdict summary
**Soft block: AI-agent control surface** — Warn by default; block when configured. Changes agent behavior without an explicit setup command and can make an authenticated API request during installation.

- **Verdict:** AI-agent control-surface policy finding
- **Product-default install policy:** Warn by default; block when configured
- **Firewall policy:** Warn by default
- **Public report status:** Published
- **Threat category:** Soft block: AI-agent control surface
- **Selected version:** 5.3.5
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

This finding concerns changes to an AI agent's instructions or configuration without explicit user action. It does not by itself establish malware intent. The CLI warns by default and blocks when configured for this policy.

AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy.

LPM flags this version as an AI-agent control-surface risk. Installing the package automatically rewrites existing Todoist skills in several foreign AI-agent configuration directories. It also performs a legacy-token migration that contacts Todoist.

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:** Installing the package automatically rewrites existing Todoist skills in several foreign AI-agent configuration directories. It also performs a legacy-token migration that contacts Todoist.

- **Trigger:** npm install runs postinstall.

- **Impact:** Changes agent behavior without an explicit setup command and can make an authenticated API request during installation.

- **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/lib/migrate-auth.js

- **Review source:** ai\_review

- **Reviewed:** 2026-09-14T07:34:53.727Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** Automatic agent-skill overwrite and legacy authentication migration.

- **Attack narrative:** A normal npm installation launches postinstall. That code detects existing Todoist skill files in multiple AI-agent configuration surfaces and overwrites them with package-provided instructions, without a user setup command. The same automatic path migrates a legacy token and sends it to Todoist's API. The local bundled content and conditional update limit scope, but do not provide consent for installation-time changes to foreign agent control surfaces.

- **Rationale:** This is an unconsented postinstall mutation of multiple foreign AI-agent control surfaces, which meets the blocking policy. The additional install-time authenticated request increases the impact.

- **Files touched:** ~/.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:** Malicious

- **Confidence:** 96.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for policy risk:** The manifest runs a postinstall script automatically., Postinstall updates installed skills and runs authentication migration., The updater overwrites every detected installed Todoist skill., It targets Claude, Codex, Copilot, Cursor, Gemini, Pi, and universal agent directories., Skill updates write files under home or project agent control paths., The migration sends a legacy token to api.todoist.com during installation., The skill updater overwrites the generated skill file at its installation path., The authentication migration sends the legacy token as a Bearer credential to Todoist's user API.

- **Evidence against:** Skill content is bundled locally; no remote skill download was found., The updater skips agent skill files that are not already installed., The network endpoint is Todoist's own API., No self-dependency, shell execution, or payload loader was found.

## Affected versions and remediation

This report applies to @doist/todoist-cli@5.3.5.

- Avoid installing @doist/todoist-cli@5.3.5. Remove it from direct dependencies and check your lockfile for transitive copies.
- Choose an independently verified alternative or release. This report does not establish that other versions are safe.
- If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment.
