## 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:** 1.3.0
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

LPM treats this as warn-only first-party agent extension lifecycle risk. npm postinstall runs local bootstrap code that refreshes Lanesmith settings and previously installed Lanesmith agent-harness assets. The refresh is scoped to detected package-owned assets, but modifies global agent command locations without an explicit command.

## Security analysis

### Published attack-surface review

- **Summary:** npm postinstall runs local bootstrap code that refreshes Lanesmith settings and previously installed Lanesmith agent-harness assets. The refresh is scoped to detected package-owned assets, but modifies global agent command locations without an explicit command.

- **Trigger:** npm installation

- **Impact:** Previously installed Lanesmith prompts, commands, skills, and default settings may be overwritten or seeded.

- **Evidence paths:** scripts/postinstall.mjs, dist/cli/bootstrap-harness.js, dist/infra/agent-harness/detect.js, dist/infra/agent-harness/install.js, dist/domain/agent-harness-locations.js, dist/infra/settings/bootstrap.js

- **Review source:** ai\_review

- **Reviewed:** 2026-08-13T09:44:06.629Z

### AI review details

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

- **Mechanism:** guarded refresh of package-owned global settings and agent-harness files

- **Rationale:** The postinstall mutation merits a warning under the agent-extension lifecycle policy, but its discovery gate and package-owned destinations prevent a malicious/block verdict. No concrete exfiltration, remote execution, or destructive chain was found.

- **Files touched:** scripts/postinstall.mjs, dist/cli/bootstrap-settings.js, dist/cli/bootstrap-harness.js, ~/.lanesmith/settings.toml, ~/.lanesmith/.default-settings/, ~/.codex/prompts, ~/.claude/commands/lanesmith, ~/.cursor/commands/lanesmith, ~/.agents/skills/lanesmith

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 92.0%

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

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for:** postinstall executes compiled global settings and harness bootstrap entries., Install-time harness refresh can overwrite previously installed Lanesmith agent assets., Harness destinations include global Codex, Claude, Cursor, Gemini, Pi, and OpenCode command paths.

- **Evidence against:** Harness refresh first discovers matching packaged filenames and does nothing when none are installed., The lifecycle hook invokes only package-local Node files; no network or remote-code loader was found., No credential harvesting, exfiltration, eval, or destructive behavior was found in inspected install code.
