Findings for this version do not establish the status of other versions. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. The manifest has no install lifecycle hook, and the flagged process execution serves package functionality when its CLI or helper is invoked. The static findings are consistent with a guidance-management CLI and do not establish malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 91.0% - **Started:** 2026-11-01T08:52:14.438Z - **Finished:** 2026-11-01T08:53:02.357Z - **Download time:** 1032 ms - **Static scan time:** 3822 ms - **AI review time:** 43064 ms - **Total time:** 47919 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:** No attack identified; the package provides a CLI for installing and managing AI-agent guidance and knowledge-base tools. - **Trigger:** The CLI and its helper commands run when a user invokes them. - **Impact:** No automatic credential collection, unrelated network contact, or unrequested account action was identified. - **Review source:** ai\_review - **Reviewed:** 2026-11-01T08:53:02.357Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The reviewed process execution is limited to running the package's sibling kb-edit helper with note and tag arguments; project context reads a Git remote URL. - **Rationale:** The manifest has no install lifecycle hook, and the flagged process execution serves package functionality when its CLI or helper is invoked. The static findings are consistent with a guidance-management CLI and do not establish malicious behavior. ### Review decision - **Verdict:** Clean - **Confidence:** 91.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest exposes a CLI and only exports package.json; it declares no install lifecycle hook., The launcher loads the CLI when the codeassembly executable runs., The flagged kb-add helper runs only when invoked as the entry point and parses command-line arguments., Tag canonicalization invokes the sibling kb-edit helper with the selected note path and tags., Session-context derivation reads a Git remote URL to build project context. ## Affected versions and remediation This report applies to codeassembly@0.12.0. - Review the evidence and your use of codeassembly@0.12.0 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.
