## Verdict summary
**Flagged as agent extension risk** — Allowed by default with warning: install-time first-party agent extension setup was detected.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Warn-only agent extension risk
- **Public report status:** Published
- **Threat category:** Agent extension lifecycle risk
- **Selected version:** 0.5.20-staging.1144.1
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

LPM treats this as warn-only first-party agent extension lifecycle risk. The user-invoked First Tree runtime can install managed skills and briefing files into its workspace's AI-agent discovery paths. This is a guarded agent-extension lifecycle, not install-time control-surface mutation.

## Security analysis

### Published attack-surface review

- **Summary:** The user-invoked First Tree runtime can install managed skills and briefing files into its workspace's AI-agent discovery paths. This is a guarded agent-extension lifecycle, not install-time control-surface mutation.

- **Trigger:** User runs the First Tree CLI/client runtime and starts or resumes an agent session.

- **Impact:** Configured agent sessions may load First Tree-managed instructions/skills.

- **Evidence paths:** package.json, scripts/prune-codex-runtime-binary.mjs, scripts/prune-claude-runtime-binary.mjs, scripts/prune-claude-sdk-deps.mjs, dist/cli/index.mjs, dist/connect-token-Bvv7ro7s.mjs

- **Review source:** ai\_review

- **Reviewed:** 2026-08-11T02:16:59.580Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** Server-configured managed-skill projection into workspace provider paths.

- **Rationale:** The malicious scanner label is not supported by the inspected lifecycle chain: no install-time credential exfiltration or broad foreign agent-control write was found. The package does provide a real, guarded AI-agent extension lifecycle, so it warrants a warning rather than a block.

- **Files touched:** \<workspace\>/.agents/skills/\<name\>, \<workspace\>/.claude/skills/\<name\>, \<workspace\>/AGENTS.md, \<workspace\>/CLAUDE.md

- **Network endpoints:** https://dev.cloud.first-tree.ai, https://5d27fb42311f9f8764ccc38823ee3ff4@o4510502633209856.ingest.us.sentry.io/4511646359486464

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 88.0%

- **Recommended action:** downgrade\_to\_warn

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for:** dist/connect-token-Bvv7ro7s.mjs reconciles server-provided skills into provider discovery roots., It writes AGENTS.md and CLAUDE.md in its managed workspace for Codex/Claude sessions., CLI imports this bundle, so the behavior is reachable after an explicit CLI/runtime action.

- **Evidence against:** package.json postinstall only runs three pruning scripts; none imports the CLI bundle., Postinstall pruning is global-install-only and targets named SDK runtime/dependency packages., Managed-skill targets are allowlisted to workspace-relative provider skill paths and use ownership/journal checks., No source evidence of credential harvesting or unrelated exfiltration was found., Network defaults are First Tree service endpoints; Sentry context is sanitized.
