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. The scanner's download and network signals map to explicit CLI project-pull and publishing flows. The starter-specific instruction to publish without separately asking creates a conditional AI-agent capability risk, so warn rather than block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 89.0% - **Started:** 2026-10-18T11:33:38.744Z - **Finished:** 2026-10-18T11:34:40.730Z - **Download time:** 1279 ms - **Static scan time:** 878 ms - **AI review time:** 59828 ms - **Total time:** 61986 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:** Starter onboarding output directs an AI assistant to publish a first change without separately asking the user. If followed, the command can deploy project changes under the user's authenticated account. - **Trigger:** A user runs the CLI pull command for a starter site and an assistant follows the returned onboarding instructions. - **Impact:** A site could be changed and deployed without a distinct user confirmation of that publication. - **Evidence paths:** dist/cli/app.js, dist/cli/publishing.js, dist/publishWire.js - **Review source:** ai\_review - **Reviewed:** 2026-10-18T11:34:40.730Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The CLI emits instructions to make a site change and publish it; the publish command uploads project files to the Pattern service using the saved session. - **Rationale:** The scanner's download and network signals map to explicit CLI project-pull and publishing flows. The starter-specific instruction to publish without separately asking creates a conditional AI-agent capability risk, so warn rather than block. - **Network endpoints:** https://onpattern.app ### Review decision - **Verdict:** Suspicious - **Confidence:** 89.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The manifest exposes a CLI and lists ordinary development scripts; no install lifecycle hook is present., The indicated agent-related locations concern formatting \`.claude\` files and ignoring that folder in an empty-folder check; they do not mutate agent settings., The explicit pull command downloads a selected site's source, and starter downloads receive a separate onboarding response., That starter onboarding response directs an assistant to publish its first change without separately asking the user., Publishing builds the project and posts its selected build and source files through the saved Pattern session., The default publishing service is onpattern.app, the package's stated service destination. - **Evidence against:** The package manifest has no install hook, so this behavior does not run automatically during npm installation., The publish action is an explicit CLI command, and the CLI describes the files sent and the destination., The remote instruction is emitted only for a starter download; ordinary pulls instead direct the user to start the project. ## Affected versions and remediation This report applies to @trypattern/sdk@0.1.12. - Review the evidence and your use of @trypattern/sdk@0.1.12 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.
