## 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:** 0.4.2
- **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.

Postinstall performs first-party setup of this SDK's own agent-skill namespace, with an optional same-vendor MCP skill sync that runs only when the operator already configured the endpoint and token. That automatic agent-surface write is a guarded lifecycle risk and is not a hidden foreign control-surface hijack or a separate exfiltration chain.

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:** A local npm install runs postinstall, which copies this package's agent skills into the consumer repository at .agents/skills/command-center. When Main Sequence MCP settings are already present, it also writes fetched platform skills under .agents/skills/mainsequence.

- **Trigger:** npm postinstall on a non-global install when INIT\_CWD names a consumer project directory.

- **Impact:** Agent runtimes that load .agents/skills receive package-authored skill text, and optionally remotely supplied skill text, without a separate install command. Writes stay inside the command-center and mainsequence namespaces.

- **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:** 2026-09-22T16:42:07.168Z

### AI review details

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

- **Mechanism:** cli/postinstall.mjs calls installAgentSkills unconditionally for that project, then calls installMcpAgentSkills after an authenticated catalog fetch unless COMMAND\_CENTER\_SDK\_MCP\_POSTINSTALL is 0 or the URL and token are missing.

- **Rationale:** Postinstall performs first-party setup of this SDK's own agent-skill namespace, with an optional same-vendor MCP skill sync that runs only when the operator already configured the endpoint and token. That automatic agent-surface write is a guarded lifecycle risk and is not a hidden foreign control-surface hijack or a separate exfiltration chain.

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

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 86.0%

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

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for warning:** package.json postinstall runs node ./cli/postinstall.mjs on install., That hook calls installAgentSkills for the consumer INIT\_CWD and labels the command npm postinstall., Copied skills land in the consumer .agents/skills/command-center tree and stale entries in that namespace are removed., If a Main Sequence MCP URL and MAINSEQUENCE\_ACCESS\_TOKEN are already set, postinstall also fetches a skill catalog and writes it under .agents/skills/mainsequence unless COMMAND\_CENTER\_SDK\_MCP\_POSTINSTALL is 0.

- **Evidence against:** Global installs and the SDK source repository are skipped, and the local copy stays inside the command-center skill namespace with symlink and path checks., The MCP URL is taken only from caller configuration, the bearer token is sent only to that URL, and a missing configuration skips the network step., No install-time shell, eval, or runtime dependency on this same package name was found.
