## 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:** 0.5.1
- **Selected version is latest:** No
- **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.

Automatic install writes first-party skills into the project agent skill directory and can pull remote skill text when MCP settings already exist. The destinations stay inside this package's namespaces and the token goes to the operator-configured MCP endpoint, so this is guarded extension setup rather than a foreign control-surface hijack.

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:** On npm install, postinstall writes this package's agent skills into the consumer project's .agents/skills/command-center directory. When Main Sequence MCP settings are present, it also downloads platform skill text and writes it under .agents/skills/mainsequence.

- **Trigger:** npm postinstall runs node ./cli/postinstall.mjs and uses INIT\_CWD as the target project.

- **Impact:** Agents that load project .agents/skills will see publisher-supplied and remotely fetched skill instructions. The access token is sent only to the operator-selected HTTP(S) MCP URL.

- **Evidence paths:** package.json, cli/postinstall.mjs, cli/install-agent-skills.mjs, cli/install-mcp-skills.mjs, cli/mcp-platform-skills.mjs

- **Review source:** ai\_review

- **Reviewed:** 2026-09-22T20:19:55.084Z

### AI review details

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

- **Mechanism:** The script copies packaged skill trees into the command-center namespace. Unless COMMAND\_CENTER\_SDK\_MCP\_POSTINSTALL is 0, it POSTs the configured access token to the configured MCP URL and writes the returned skill files into the mainsequence namespace.

- **Rationale:** Automatic install writes first-party skills into the project agent skill directory and can pull remote skill text when MCP settings already exist. The destinations stay inside this package's namespaces and the token goes to the operator-configured MCP endpoint, so this is guarded extension setup rather than a foreign control-surface hijack.

- **Files touched:** .agents/skills/command-center, .agents/skills/mainsequence

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 81.0%

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

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for warning:** npm postinstall runs node ./cli/postinstall.mjs., Postinstall copies packaged skills into the consumer project under .agents/skills/command-center using INIT\_CWD., Unless COMMAND\_CENTER\_SDK\_MCP\_POSTINSTALL is 0, postinstall fetches platform skills with MAINSEQUENCE\_ACCESS\_TOKEN and writes them under .agents/skills/mainsequence., The MCP URL is any absolute http or https URL from environment variables, and the bearer token is sent there with no host allowlist.

- **Evidence against:** Global installs and the SDK source repository are skipped., Writes stay inside the command-center and mainsequence skill namespaces, with symlink and path checks., MCP sync is skipped when the URL or token is missing, and a fetch failure does not fail the install., Dependencies are lucide-react plus React peers. No eval, self-dependency, or fixed package-controlled exfiltration host.
