## Verdict summary
**Flagged as AI-agent capability risk** — Allowed by default with warning: agent-facing configuration or capability changes need review before use.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Warn-only AI-agent capability risk
- **Public report status:** Published
- **Threat category:** AI-agent capability abuse
- **Selected version:** 0.8.0
- **Selected version is latest:** Yes
- **Analysis source:** AI Security Review (lpm-firewall-ai)

This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions.

AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy.

Review flagged AI-agent configuration or capability changes. This remains warn-only unless evidence shows foreign-agent hijack through preinstall/install/postinstall, hidden persistence, exfiltration, remote code execution, or other concrete malicious behavior.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Suspicious
- **Recorded analysis confidence:** 94.0%

The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs.

## Security analysis

### Published attack-surface review

- **Summary:** An explicit CLI command modifies AI-agent MCP configuration and installs a package skill. This warrants a capability warning; no automatic installation attack was established.

- **Trigger:** The user runs pindoupic install.

- **Impact:** Changes which tools and instructions an agent can load, with backups, dry-run and undo support.

- **Evidence paths:** dist/cli.js

- **Review source:** ai\_review

- **Reviewed:** 2026-10-03T11:48:02.768Z

### AI review details

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

- **Mechanism:** Host detection selects configuration destinations; the installer merges its server entry and copies or links its skill.

- **Rationale:** The explicit agent configuration and skill installation capability warrants a warning under the supplied policy. The absence of automatic install hooks and the inspected package-aligned execution and network behavior do not support a malware block.

- **Files touched:** ~/.agents/skills

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 94.0%

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

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for warning:** package.json has no preinstall, install, or postinstall hook and no runtime self-dependency., dist/cli.js activates agent setup through the explicit install command., The installer writes its MCP entry into host configuration files, with backups and a dry-run gate., The installer copies its skill into ~/.agents/skills and links it into host skill directories., dist/mcp.js invokes sips with fixed arguments for local PDF conversion.

- **Evidence against:** Configuration changes preserve other server entries and include backup and undo support., Inspected telemetry sends usage parameters and anonymous identifiers; no credential harvesting or command-output exfiltration was established.
