## 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:** 0.5.2
- **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 always installs this package's own skills under .agents/skills/command-center and, unless opted out, forwards MAINSEQUENCE\_ACCESS\_TOKEN to an operator-chosen HTTP(S) MCP URL before writing returned skills under .agents/skills/mainsequence. That is first-party agent-extension setup with conditional credential exposure, not a hardcoded 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:** Local npm postinstall copies this package's agent skills into .agents/skills/command-center in the consumer project. If Main Sequence MCP settings are already present and the opt-out is unset, it also sends the access token to that configured URL and writes the returned skill files under .agents/skills/mainsequence.

- **Trigger:** npm postinstall on a non-global install, using INIT\_CWD as the target repository.

- **Impact:** Vendor agent skill directories in the consumer project are replaced during install. The access token can be sent to whatever HTTP(S) endpoint the operator configured, which is conditional exposure rather than a hardcoded recipient.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-09-23T23:13:47.020Z

### AI review details

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

- **Mechanism:** installAgentSkills copies packaged skill trees and prunes other files in the command-center namespace. fetchPlatformSkillCatalog then POSTs MAINSEQUENCE\_ACCESS\_TOKEN as a bearer credential to the operator HTTP(S) URL, and installMcpAgentSkills writes the catalog.

- **Rationale:** Postinstall always installs this package's own skills under .agents/skills/command-center and, unless opted out, forwards MAINSEQUENCE\_ACCESS\_TOKEN to an operator-chosen HTTP(S) MCP URL before writing returned skills under .agents/skills/mainsequence. That is first-party agent-extension setup with conditional credential exposure, not a hardcoded foreign control-surface hijack.

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

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 84.0%

- **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., Local postinstall calls installAgentSkills with command npm postinstall and copies skills into the consumer project., The skill destination is .agents/skills/command-center, and entries in that namespace that are not in the packaged set are removed., Unless COMMAND\_CENTER\_SDK\_MCP\_POSTINSTALL is 0, a present MAINSEQUENCE\_ACCESS\_TOKEN is sent as a bearer token to any operator HTTP(S) MCP URL, and returned skills are written under .agents/skills/mainsequence.

- **Evidence against:** There is no preinstall hook, no runtime dependency on this package name, and dist/index.js only re-exports resource modules., The MCP URL is taken from the environment, sync is skipped when the URL or token is missing, and fetch errors do not fail the install., Skill copies stay inside the command-center and mainsequence namespaces and reject symbolic links and parent-directory paths., child\_process helpers live in CLI maintenance modules and are not called by postinstall.
