## Verdict summary
**Soft block: AI-agent control surface** — Warn by default; block when configured. Disables or alters bundled Codex/Claude runtime availability and removes SDK peers.

- **Verdict:** Malicious
- **Product-default install policy:** Block
- **Firewall policy:** Warn by default
- **Public report status:** Published
- **Threat category:** Soft block: AI-agent control surface
- **Selected version:** 0.5.20
- **Selected version is latest:** Yes
- **Analysis source:** AI Security Review (lpm-firewall-ai)

LPM flags this version as an AI-agent control-surface risk. Installing globally triggers unconsented deletion of installed OpenAI and Anthropic runtime/dependency packages. This alters foreign AI-agent executables in the global package tree.

## Security analysis

### Published attack-surface review

- **Summary:** Installing globally triggers unconsented deletion of installed OpenAI and Anthropic runtime/dependency packages. This alters foreign AI-agent executables in the global package tree.

- **Trigger:** npm install -g first-tree

- **Impact:** Disables or alters bundled Codex/Claude runtime availability and removes SDK peers.

- **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, context-integration/codex/plugins/first-tree-context/hooks/hooks.json

- **Review source:** ai\_review

- **Reviewed:** 2026-08-11T12:27:07.536Z

### AI review details

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

- **Mechanism:** postinstall recursive deletion of foreign AI runtime packages

- **Attack narrative:** On global installation, package.json automatically executes pruning scripts. Those scripts resolve and recursively remove platform packages containing OpenAI Codex and Anthropic Claude runtimes, plus Claude SDK peer packages, from the installed dependency tree. The deletion is not initiated by a user command and modifies foreign AI-agent components.

- **Rationale:** The postinstall hook concretely deletes foreign AI runtime packages during installation. Global-only scope and opt-outs reduce breadth but do not make the unconsented lifecycle mutation safe.

- **Files touched:** package.json, node\_modules/@openai/codex-\*/, node\_modules/@anthropic-ai/claude-agent-sdk-\*/, node\_modules/@anthropic-ai/sdk/, node\_modules/@modelcontextprotocol/sdk/

### Review decision

- **Verdict:** Malicious

- **Confidence:** 96.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for:** package.json runs three scripts via postinstall., scripts/prune-codex-runtime-binary.mjs recursively deletes @openai/codex-\* during global install., scripts/prune-claude-runtime-binary.mjs recursively deletes @anthropic-ai/claude-agent-sdk-\* during global install., scripts/prune-claude-sdk-deps.mjs deletes two other installed Claude SDK peer packages.

- **Evidence against:** Pruning is limited to npm global installs and has opt-out environment variables., Inspected lifecycle scripts make no network requests or credential reads., Context plugin hooks invoke first-tree commands only after explicit context activation.
