The package is an agent-management CLI that can install managed skills and session hooks when its context integration is activated. Its postinstall hook deletes selected bundled agent-runtime dependencies only from its global-install tree. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 78.0% - **Started:** 2026-07-30T12:17:51.920Z - **Finished:** 2026-07-30T12:18:39.588Z - **Download time:** 510 ms - **Static scan time:** 6514 ms - **AI review time:** 40643 ms - **Total time:** 47668 ms ## Security analysis ### Published attack-surface review - **Summary:** The package is an agent-management CLI that can install managed skills and session hooks when its context integration is activated. Its postinstall hook deletes selected bundled agent-runtime dependencies only from its global-install tree. - **Trigger:** Global npm installation; subsequent explicit CLI/context-integration activation. - **Impact:** Can alter availability of bundled Codex/Claude runtime artifacts and project agent-skill content; no confirmed exfiltration or foreign control-surface mutation. - **Evidence paths:** package.json, scripts/prune-codex-runtime-binary.mjs, scripts/prune-claude-runtime-binary.mjs, scripts/prune-claude-sdk-deps.mjs, dist/connect-token-CENYco9m.mjs, dist/cli/index.mjs - **Review source:** ai\_review - **Reviewed:** 2026-07-30T12:18:39.588Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** global dependency pruning and managed AI-agent skill projection - **Rationale:** The scanner's claimed command-output exfiltration was not substantiated: command and fetch primitives are used for local runtime checks and configured First Tree API flows. The lifecycle deletion and managed agent-skill projection still warrant a warning. - **Files touched:** package.json, scripts/prune-codex-runtime-binary.mjs, scripts/prune-claude-runtime-binary.mjs, scripts/prune-claude-sdk-deps.mjs, context-integration/claude-code/plugins/first-tree-context/hooks/hooks.json, context-integration/codex/plugins/first-tree-context/bin/context-session-start - **Network endpoints:** https://download.first-tree.ai/releases ### Review decision - **Verdict:** Suspicious - **Confidence:** 78.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for:** package.json runs three postinstall scripts., Prune scripts recursively delete bundled Codex/Claude packages during global installs., dist/connect-token-CENYco9m.mjs reconciles managed skills into .agents/skills and .claude/skills., context-integration hooks invoke first-tree context activation. - **Evidence against:** Postinstall deletion is gated on npm\_config\_global=true and package-specific paths., No lifecycle script sends files, command output, or credentials over the network., Network API calls use configured First Tree server URLs and authenticated CLI/SDK flows., Runtime npm installs are exposed as named daemon install-codex/install-claude commands. ## Public findings ### 1.
