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. Inspected source is a coding-agent CLI with no install hooks and no hidden exfiltration; scanner high-severity hits are minified vendor and example files plus expected agent shell tools. Remaining risk is incomplete AST coverage of those blobs, an unreadable Doom WASM example, and unpinned GitHub binary downloads, so this is a warning rather than a block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 68.0% - **Started:** 2026-09-16T19:26:06.038Z - **Finished:** 2026-09-16T19:31:38.827Z - **Download time:** 1266 ms - **Static scan time:** 3146 ms - **AI review time:** 328376 ms - **Total time:** 332789 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:** This is a user-invoked coding-agent CLI with no npm install lifecycle. Remaining concern is incomplete static coverage of minified vendor and Doom WebAssembly example files, plus runtime download of latest GitHub fd and ripgrep binaries. - **Trigger:** The user installs the package and later runs the CLI, loads example extensions, or uses find/grep tools that fetch helper binaries. - **Impact:** No install-time compromise is shown. Runtime shell use and GitHub binary download remain user-activated product behavior, with incomplete analysis of minified and binary blobs. - **Evidence paths:** examples/extensions/doom-overlay/doom/build/doom.js, dist/core/export-html/vendor/highlight.min.js, dist/utils/tools-manager.js - **Review source:** ai\_review - **Reviewed:** 2026-09-16T19:31:38.827Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Dual-use agent runtime plus unparsed minified and WebAssembly example assets - **Rationale:** Inspected source is a coding-agent CLI with no install hooks and no hidden exfiltration; scanner high-severity hits are minified vendor and example files plus expected agent shell tools. Remaining risk is incomplete AST coverage of those blobs, an unreadable Doom WASM example, and unpinned GitHub binary downloads, so this is a warning rather than a block. - **Network endpoints:** api.github.com, github.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 68.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** High - **Evidence for warning:** Package advertises a coding-agent CLI with bash, edit, and write tools, which is dual-use by design., The Doom example ships minified Emscripten glue that static parsers cannot fully cover, plus a companion WebAssembly binary., Vendored highlight.min.js is minified Highlight.js and likewise fails complete AST coverage., At runtime the agent downloads the latest GitHub release assets for fd and ripgrep and executes them., Shared exec and shell helpers spawn child processes when the user runs the agent., Example extensions run PowerShell toast commands and the GitHub CLI after the user loads them. - **Evidence against:** package.json has no preinstall, install, or postinstall scripts., Runtime dependencies are same-vendor @leanandmean packages, not a nested self-lifecycle chain., High-similarity hits are Highlight.js vendor code, Doom Emscripten glue, and documented sample extensions., Install telemetry sending was removed; the remaining flag only reads a setting or env value., Inspected network use is GitHub tool downloads and documented AI provider URLs, not a hidden drop host., dist/index.js only re-exports SDK modules and does not run install-time side effects. ## Affected versions and remediation This report applies to @leanandmean/coding-agent@0.74.1-scramjet.51. - Review the evidence and your use of @leanandmean/coding-agent@0.74.1-scramjet.51 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.
