Install-time code provisions a user-home Python environment, may globally install Claude Code, and persists a PATH entry/launcher. No automatic write to the shared Claude plugin configuration was confirmed. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 86.0% - **Started:** 2026-08-17T02:47:43.061Z - **Finished:** 2026-08-17T02:48:56.349Z - **Download time:** 521 ms - **Static scan time:** 107 ms - **AI review time:** 72659 ms - **Total time:** 73288 ms ## Security analysis ### Published attack-surface review - **Summary:** Install-time code provisions a user-home Python environment, may globally install Claude Code, and persists a PATH entry/launcher. No automatic write to the shared Claude plugin configuration was confirmed. - **Trigger:** npm postinstall - **Impact:** Unexpected global dependency installation and persistent user-environment changes; agent hooks are runtime behavior for cockpit-spawned panes. - **Evidence paths:** package.json, npm/scripts/postinstall.js, npm/scripts/pathfix.js, npm/scripts/shortcut.js, dist/agent\_takkub-1.0.71-py3-none-any.whl - **Review source:** ai\_review - **Reviewed:** 2026-08-17T02:48:56.349Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** lifecycle provisioning and persistent desktop/shell integration - **Rationale:** The postinstall behavior is materially invasive and the package includes agent-control capabilities, warranting a warning. It does not meet the block threshold because no unconsented install-time mutation of a foreign/broad AI-agent control surface or exfiltration was confirmed. - **Files touched:** dist/agent\_takkub-1.0.71-py3-none-any.whl, npm/scripts/postinstall.js, npm/scripts/pathfix.js, npm/scripts/shortcut.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 86.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for:** \`postinstall\` creates/reuses a user-home virtual environment and installs the bundled wheel with pip., When Claude is absent, installation automatically runs a global install of \`@anthropic-ai/claude-code\`., The lifecycle script persistently adjusts PATH and creates a desktop launcher; the bundled app also supports guarded hooks for cockpit-spawned agent panes. - **Evidence against:** Lifecycle source states it does not automatically modify \`~/.claude\` plugins or \`~/.takkub\` config., Shared Claude plugin/MCP setup is behind the explicit \`takkub provision\` command., No credential harvesting, exfiltration endpoint, obfuscated payload execution, or foreign agent-control-surface write was confirmed. ## Public findings ### 1.
