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 comms-cli SKILL.md files in several home-directory coding-agent skill folders. It does not create those files unless a prior tdc skill install put them there. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 86.0% - **Started:** 2026-09-17T03:13:29.312Z - **Finished:** 2026-09-17T03:16:29.990Z - **Download time:** 763 ms - **Static scan time:** 576 ms - **AI review time:** 179338 ms - **Total time:** 180678 ms The recorded confidence comes from the underlying analysis.

It does not create those files unless a prior tdc skill install put them there. - **Trigger:** npm install of this package after a user has already run tdc skill install for one or more agents - **Impact:** Agents that load those skills get refreshed Comms CLI instructions, including how to print stored tokens. - **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/skills/content.js - **Review source:** ai\_review - **Reviewed:** 2026-09-17T03:16:29.990Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall overwrite of first-party agent SKILL.md files - **Rationale:** Postinstall only refreshes this package's own comms-cli SKILL.md in agent skill folders that already contain it, which is first-party agent extension setup rather than a new hijack of unrelated agent config. The malware fingerprint on dist/lib/input.js is a false lead: that file only reads stdin and opens a local editor. - **Files touched:** ~/.claude/skills/comms-cli/SKILL.md, ~/.codex/skills/comms-cli/SKILL.md, ~/.cursor/skills/comms-cli/SKILL.md, ~/.gemini/skills/comms-cli/SKILL.md, ~/.pi/skills/comms-cli/SKILL.md, ~/.agents/skills/comms-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 postinstall runs scripts/postinstall.js on every npm install., dist/postinstall.js silently updates already-installed agent skills in the home directory and swallows errors., The installer writes SKILL.md under home-directory agent folders such as .claude, .codex, .cursor, .gemini, .pi, and .agents., The skill text tells agents how to print saved API and OAuth refresh tokens with tdc auth token view. - **Evidence against:** Postinstall only updates a skill file that already exists; it does not plant a new skill., The written path is always skills/comms-cli/SKILL.md, this package's own first-party skill., User-invoked global install refuses to write unless that agent directory already exists, except for .agents., dist/lib/input.js is a stdin and local-editor helper; the malware fingerprint on it does not match the source., Network hosts are Todoist, Comms, and GitHub endpoints used by this CLI; there is no self-dependency, eval, or remote payload. ## Affected versions and remediation This report applies to @doist/comms-cli@3.1.0. - Review the evidence and your use of @doist/comms-cli@3.1.0 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.
