## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 12 low-signal pattern(s) reviewed.

- **Verdict:** Clean
- **Product-default install policy:** Allow
- **Firewall policy:** No policy match
- **Public report status:** Published
- **Threat category:** None published
- **Selected version:** 5.5.0
- **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: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy.

The flagged agent configuration behavior is scoped to the package’s collection skill authoring and import workflow, with workspace path and file allowlisting. Inspected evidence did not establish install-hook activation, broad unrelated agent configuration changes, credential exposure, or another concrete attack.

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:** No attack was identified. The reviewed configuration writes support skill files and schemas in the package’s collection workflow.

- **Trigger:** A collection authoring or import operation in the consuming application.

- **Impact:** The operation makes authored or imported collection skills available to the application’s Claude integration; no harmful control change was established.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-09T06:46:20.449Z

### AI review details

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

- **Mechanism:** Validated skill files from workspace staging are mirrored into that workspace’s .claude/skills directory; schema mirroring follows a schema write.

- **Rationale:** The flagged agent configuration behavior is scoped to the package’s collection skill authoring and import workflow, with workspace path and file allowlisting. Inspected evidence did not establish install-hook activation, broad unrelated agent configuration changes, credential exposure, or another concrete attack.

- **Files touched:** .claude/skills/\<slug\>

### Review decision

- **Verdict:** Clean

- **Confidence:** 78.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** package.json identifies this as a shared MulmoClaude and MulmoTerminal core package., The registry import behavior installs skills under the active .claude/skills directory when no staging bridge exists; with staging, skill files are mirrored into that directory., The skill bridge limits mirrored paths to validated skill slugs and allowed files under the workspace staging directory., Schema mirroring is tied to a schema write operation in the collection server, consistent with package-owned collection authoring., The flagged server bundle excerpts describe source-aware collection view handling; the flagged discovery, prompt safety, and Google files inspected begin with ordinary module imports.

## Public findings

### 1. Low: Scripts Present
- **Category:** Manifest
- **Confidence:** 100.0%

Package declares npm scripts.

### 2. Medium: Network

### 5. High: Copied Package Dependency Bridge
- **Category:** Source
- **Confidence:** 83.0%
- **Path:** dist/discovery-B79IxEM6.cjs
- **Public source:** [View source](<https://unpkg.com/@mulmoclaude/core@5.5.0/dist/discovery-B79IxEM6.cjs>)

Package metadata claims a different repository identity while copied source loads a runtime dependency bridge.

Public source snippet (untrusted):

```javascript
package = @mulmoclaude/core; repositoryIdentity = mulmoclaude; dependency = @duckdb/node-api
L1450: async function duckDbInstance() {
L1451: if (instancePromise === null) instancePromise = import("@duckdb/node-api").then((mod) => mod.DuckDBInstance.create(":memory:"));
L1452: try {
```

### 6. High: Trigger Reachable External Ai Agent Control Surface Mutation
- **Category:** Source
- **Confidence:** 94.0%
- **Path:** dist/skill-bridge/index.js
- **Public source:** [View source](<https://unpkg.com/@mulmoclaude/core@5.5.0/dist/skill-bridge/index.js>)

Manifest-trigger-reachable source writes behavior-bearing configuration into a user or project AI-agent control surface.

Public source snippet (untrusted):

```javascript
Manifest-trigger-reachable source links an external AI-agent control path to a behavior-bearing write operation.
import { t as issafeactiontemplatepath } from "../templatepath-k_wnbl_q.js";
import { mkdirsync, readfilesync, renamesync, rmsync, writefilesync } from "node:fs";
import path from "node:path";
                                   
var data_skills_dir = path.join("data", "skills");
var claude_skills_dir = path.join(".claude", "skills");
var sk[redacted] = "skill.md";
var schema_filename = "schema.json";
var slug_re = /^[a-z0-9]+(-[a-z0-9]+)*$/;
var rm_re = /^\s*rm\s+((?:-[a-za-z]+\s+)+)['"]?data\/skills\/([a-z0-9-]+)\/?['"]?\s*$/;

### 10. Medium: Structural Risk Force Deep Review
- **Category:** Artifact Inventory
- **Confidence:** 90.0%

Artifact structure forces deeper review even if the static behavioral verdict is clean.

### 11. High: Semantic Analysis Limited
- **Category:** Scanner Coverage
- **Confidence:** 100.0%
- **Path:** dist/promptSafety-caJWd1ZQ.cjs\#virtual:normalized:round1
- **Public source:** [View source](<https://unpkg.com/@mulmoclaude/core@5.5.0/dist/promptSafety-caJWd1ZQ.cjs%23virtual%3Anormalized%3Around1>)

A bounded semantic-analysis stage reached its safety limit; remaining detectors completed, but this package requires AI review.

Public source snippet (untrusted):

```text
stage = ast_semantic_analysis; reason = ast_parse_error; limitedFiles = 2
```

### 12. High: Previous Version Dangerous Delta
- **Category:** Supply Chain
- **Confidence:** 93.0%
- **Path:** dist/google/index.cjs
- **Public source:** [View source](<https://unpkg.com/@mulmoclaude/core@5.5.0/dist/google/index.cjs>)

This package version adds a dangerous source file absent from the previous stored version; route for source-aware review.

Public source snippet (untrusted):

```javascript
matchType = previous_version_dangerous_delta
matchedPackage = @mulmoclaude/core@4.9.3
matchedIdentity = npm:QG11bG1vY2xhdWRlL2NvcmU:4.9.3
similarity = 0.900
