Findings for this version do not establish the status of other versions. AI assessment: manual review; recommendation: manual review. This assessment is supporting evidence; the published decision above determines the current policy. The inspected manifest has no install lifecycle hook, and the inspected entrypoints show no confirmed attack behavior. Manual review is needed because selected runtime dependencies imported by the main entry and CLI could not be assessed from the available source snapshot. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 82.0% - **Started:** 2026-10-21T12:27:08.159Z - **Finished:** 2026-10-21T12:28:18.734Z - **Download time:** 2283 ms - **Static scan time:** 53 ms - **AI review time:** 68238 ms - **Total time:** 70575 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:** A review gap remains because the main entry and CLI load runtime dependencies whose implementation could not be verified. No concrete attack is confirmed in the inspected package-owned entrypoints. - **Trigger:** Importing the package or launching its CLI. - **Impact:** No concrete impact is confirmed; the behavior of these imported dependencies remains unresolved. - **Evidence paths:** dist/index.js, cli.mjs - **Review source:** ai\_review - **Reviewed:** 2026-10-21T12:28:18.734Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The main entry re-exports runtime code from @tscircuit/core and @tscircuit/eval; the CLI imports @tscircuit/cli. - **Rationale:** The inspected manifest has no install lifecycle hook, and the inspected entrypoints show no confirmed attack behavior. Manual review is needed because selected runtime dependencies imported by the main entry and CLI could not be assessed from the available source snapshot. - **Files touched:** dist/index.js, cli.mjs ### Review decision - **Verdict:** Manual Review - **Confidence:** 82.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** The main entry re-exports @tscircuit/core and @tscircuit/eval, whose runtime behavior could not be verified from the available sources., Running the CLI imports @tscircuit/cli, whose implementation could not be verified from the available sources., The package manifest lists build and helper scripts but no install lifecycle hook. - **Evidence against:** No malicious behavior is confirmed by the inspected package-owned entrypoint code. ## Affected versions and remediation This report applies to tscircuit@0.0.2987. - Review the evidence and your use of tscircuit@0.0.2987 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.
