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 package performs broad but explicit CLI-driven project mutation and source-to-LLM processing. Because it lacks automatic lifecycle execution and the observed behavior is package-aligned, it warrants a warning rather than a publish block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 85.0% - **Started:** 2026-09-07T11:46:41.253Z - **Finished:** 2026-09-07T11:47:26.581Z - **Download time:** 506 ms - **Static scan time:** 457 ms - **AI review time:** 44364 ms - **Total time:** 45328 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 automatic install-time attack surface is present. An explicit setup command can install first-party packages and modify the selected project's integration files and build hook. - **Trigger:** The user runs \`cairn setup \[dir\]\`. - **Impact:** It can change the target project's dependencies, \`.env\`, UI integration files, and \`package.json\` prebuild behavior; LLM builds can transmit scanned source to the chosen provider. - **Evidence paths:** dist/cli.js, dist/setup.js, dist/l3-describe.js, dist/llm.js - **Review source:** ai\_review - **Reviewed:** 2026-09-07T11:47:26.581Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Explicit CLI-driven project scaffolding, dependency installation, and build-hook configuration. - **Rationale:** The package performs broad but explicit CLI-driven project mutation and source-to-LLM processing. Because it lacks automatic lifecycle execution and the observed behavior is package-aligned, it warrants a warning rather than a publish block. - **Files touched:** .env, package.json, ui-manifest.json ### Review decision - **Verdict:** Suspicious - **Confidence:** 85.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The explicit \`cairn setup\` command installs packages into the selected project, including this package name., That setup command writes a \`.env\` file from keys entered by the user and modifies the target project's build script., The CLI can scan application source and send up to 12,000 characters of each page source to a configured Anthropic or Groq client. - **Evidence against:** package.json has no preinstall, install, postinstall, or other lifecycle hook., The project-changing behavior is reached only through the explicit \`cairn setup\` CLI command., The observed network use is tied to user-configured LLM providers; no hidden endpoint or credential exfiltration path was found., The child-process use in manifest generation runs a fixed git command. ## Affected versions and remediation This report applies to @cairnvibe/indexer@0.2.3. - Review the evidence and your use of @cairnvibe/indexer@0.2.3 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.
