## Verdict summary
**Soft block: AI-agent control surface** — Warn by default; block when configured. Claude Code loads attacker-chosen skill instructions from the user's home skills directory without a separate consent prompt.

- **Verdict:** AI-agent control-surface policy finding
- **Product-default install policy:** Warn by default; block when configured
- **Firewall policy:** Warn by default
- **Public report status:** Published
- **Threat category:** Soft block: AI-agent control surface
- **Selected version:** 0.24.3
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

This finding concerns changes to an AI agent's instructions or configuration without explicit user action. It does not by itself establish malware intent. The CLI warns by default and blocks when configured for this policy.

AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy.

LPM flags this version as an AI-agent control-surface risk. On npm install, the postinstall hook writes this package's skill markdown into the user-level Claude Code skills directory. The write is on by default and is not limited to a global install.

## Security analysis

### Published attack-surface review

- **Summary:** On npm install, the postinstall hook writes this package's skill markdown into the user-level Claude Code skills directory. The write is on by default and is not limited to a global install.

- **Trigger:** npm install or any install that runs the package postinstall script.

- **Impact:** Claude Code loads attacker-chosen skill instructions from the user's home skills directory without a separate consent prompt.

- **Evidence paths:** package.json, scripts/postinstall.mjs, dist/cli/skills-install.js

- **Review source:** ai\_review

- **Reviewed:** 2026-09-26T05:26:32.091Z

### AI review details

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

- **Mechanism:** scripts/postinstall.mjs spawnSyncs node on dist/cli/skills-install.js, which mkdir and copyFile package skills into os.homedir()/.claude/skills unless EMDEE\_SKIP\_POSTINSTALL is 1.

- **Attack narrative:** Installing the package runs postinstall, which launches the bundled skills installer. That installer creates ~/.claude/skills if needed and copies the package skill markdown there, overwriting existing names. Claude Code treats that directory as its skill control surface, so the install changes agent behavior without a user command. Setting EMDEE\_SKIP\_POSTINSTALL=1 is the only gate, and it is off by default.

- **Rationale:** The install hook unconditionally mutates Claude Code's user-level skills directory, a foreign agent control surface, unless an opt-out variable is already set. The copied content is this package's own skills, but the write itself is unconsented and broad.

- **Files touched:** ~/.claude/skills

### Review decision

- **Verdict:** Malicious

- **Confidence:** 86.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for policy risk:** npm postinstall runs node scripts/postinstall.mjs on install., That hook spawns dist/cli/skills-install.js unless EMDEE\_SKIP\_POSTINSTALL is exactly 1., skills-install copies package markdown skills into ~/.claude/skills by default, creating the directory and overwriting files.

- **Evidence against:** The hook copies only this package's .md skill files and does not open a network connection., An environment variable can skip the hook, and the same copy is also available as an explicit CLI command.

## Affected versions and remediation

This report applies to @aisystemresources/emdee@0.24.3.

- Avoid installing @aisystemresources/emdee@0.24.3. Remove it from direct dependencies and check your lockfile for transitive copies.
- Choose an independently verified alternative or release. This report does not establish that other versions are safe.
- If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment.
