## Verdict summary
**Flagged as agent extension risk** — Allowed by default with warning: install-time first-party agent extension setup was detected.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Warn-only agent extension risk
- **Public report status:** Published
- **Threat category:** Agent extension lifecycle risk
- **Selected version:** 5.3.8
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

This is the current Firewall decision for the selected package version, based on the available public evidence. 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. On npm install, postinstall overwrites this package's already-installed Todoist CLI skill files in several coding-agent home directories. New skill placement still requires an explicit td skill install command.

## Security analysis

### Published attack-surface review

- **Summary:** On npm install, postinstall overwrites this package's already-installed Todoist CLI skill files in several coding-agent home directories. New skill placement still requires an explicit td skill install command.

- **Trigger:** npm install or upgrade of @doist/todoist-cli, which runs the postinstall script.

- **Impact:** Previously opted-in agent skills are replaced with this release's bundled skill text without another prompt.

- **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:** 2026-09-18T23:46:29.791Z

### AI review details

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

- **Mechanism:** silent overwrite of existing todoist-cli SKILL.md files in agent skill directories

- **Rationale:** The postinstall hook refreshes this package's own Todoist CLI skill files in coding-agent directories only when those skills already exist, which is first-party extension maintenance rather than an unconsented hijack. Doctor.js and Todoist API usage are product-aligned, and the scanner malware fingerprint does not match attack behavior in source.

- **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

### 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 runs node scripts/postinstall.js after every install., postinstall silently refreshes already-installed global agent skills and migrates legacy Todoist auth., Skill installers target this package's SKILL.md under .claude, .codex, .copilot, .cursor, .gemini, .pi, and .agents., The updater overwrites that skill file whenever the todoist-cli skill is already present.

- **Evidence against:** New skill files are created only by an explicit td skill install command; postinstall skips agents without an existing todoist-cli skill., doctor.js is a user-invoked health check against Todoist credentials and the npm registry, not an install-time payload., Network use is Todoist and GitHub aligned; there is no self-dependency or unrelated exfil sink., The scanner malware fingerprint does not match any hidden attack in source.
