It installs package-owned onboarding skills pointing to a local Agent Inspector MCP/proxy. - **Trigger:** npm postinstall when ~/.claude or ~/.codex exists, unless opt-out environment variables are set. - **Impact:** Adds a local AI-agent extension that guides/configures use of the package's MCP and traffic-capture proxy. - **Evidence paths:** package.json, scripts/setup-agent-skills.mjs, src/cli/onboard.ts, src/cli/templates/codex-skill-onboard.ts - **Review source:** ai\_review - **Reviewed:** 2026-07-28T18:08:49.504Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** guarded postinstall agent-skill installation via bundled CLI - **Rationale:** This is a concrete, guarded install-time AI-agent extension lifecycle mutation, so it warrants a warning under policy. Source inspection found no concrete malicious chain such as remote payload execution or credential exfiltration. - **Files touched:** scripts/setup-agent-skills.mjs, src/cli/onboard.ts, ~/.claude/skills/agent-inspector-onboard/SKILL.md, ~/.claude/commands/agent-inspector:onboard.md, ~/.codex/skills/agent-inspector-onboard/SKILL.md - **Network endpoints:** http://localhost:9527/api/mcp, http://localhost:9527/proxy ### Review decision - **Verdict:** Suspicious - **Confidence:** 94.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** package.json postinstall invokes scripts/setup-agent-skills.mjs., That script detects existing ~/.claude or ~/.codex and silently runs the bundled onboard CLI., src/cli/onboard.ts writes package-generated Claude/Codex skill files; this occurs on install when those homes exist., Generated skill configures a local MCP/proxy that can access captured provider traffic. - **Evidence against:** The generated Codex skill explicitly says not to read auth/token files., Reviewed onboarding targets use localhost:9527 only; no remote install-time endpoint is present., No remote payload loading, credential exfiltration, or covert shell download was found in reviewed lifecycle/onboarding sources., scripts/setup-windows-runtime.mjs only brands a local Windows runtime and is Windows-guarded. ## Public findings ### 1.
