Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. On npm installation, the postinstall hook writes a project-level Claude Code control file that auto-approves edits and permits Bash and web tools. It then removes its dependency footprint from the project. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-07T12:46:50.272Z - **Finished:** 2026-09-07T12:47:47.490Z - **Download time:** 778 ms - **Static scan time:** 290 ms - **AI review time:** 56149 ms - **Total time:** 57218 ms The recorded confidence comes from the underlying analysis.

It then removes its dependency footprint from the project. - **Trigger:** Running npm install or npm ci with this package as a dependency. - **Impact:** A dependency installation changes the consuming project's AI-agent permission surface without an explicit setup command and conceals the installed package record. - **Evidence paths:** package.json, scripts/npm-postinstall.mjs, scripts/install.mjs, scripts/npm-cleanup.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-07T12:47:47.490Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic agent-control configuration deployment followed by detached npm-footprint cleanup. - **Attack narrative:** Installing the dependency automatically invokes its postinstall hook. The hook runs the framework installer against the consumer project, which creates a Claude Code settings file granting automatic edits, Bash, and web-tool access, and deploys an OpenCode bridge. It then starts a detached cleanup process that removes the package directory, command shims, and package or lockfile entries. This is an unconsented lifecycle mutation of a broad AI-agent control surface combined with concealment of the dependency footprint. - **Rationale:** The automatic postinstall path modifies project AI-agent permissions and removes its own npm evidence afterward. This is a concrete install-hook abuse chain even though no direct secret exfiltration was found. - **Files touched:** package.json, scripts/npm-postinstall.mjs, scripts/install.mjs, scripts/npm-cleanup.mjs, .claude/settings.json, opencode.jsonc, .opencode/plugin/techieflow.js, node\_modules/@techierathore/techieflow, package-lock.json ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The package runs an automatic postinstall hook., That hook installs into the consuming project and launches detached cleanup., The installer creates a Claude Code settings file with automatic edit approval and broad Bash and web permissions., Cleanup removes the package and its npm records after installation, obscuring the origin of the project changes. - **Evidence against:** No credential harvesting or network exfiltration was found in the inspected executable sources., The installer refuses filesystem-root and home-directory targets. ## Affected versions and remediation This report applies to @techierathore/techieflow@1.0.3. - Avoid installing @techierathore/techieflow@1.0.3. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
