## 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:** 0.5.1
- **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. Install-time code mutates the consuming project by creating .agents symlinks and installing package-provided Git-hook symlinks. No credential harvesting, remote payload retrieval, or exfiltration was found.

## Security analysis

### Published attack-surface review

- **Summary:** Install-time code mutates the consuming project by creating .agents symlinks and installing package-provided Git-hook symlinks. No credential harvesting, remote payload retrieval, or exfiltration was found.

- **Trigger:** npm install runs postinstall

- **Impact:** Consumer agent instructions and Git hook behavior are changed without an explicit CLI command.

- **Evidence paths:** package.json, bin/cli.js, hooks/git/commit-msg, hooks/git/pre-push, hooks/agent/session-start.sh

- **Review source:** ai\_review

- **Reviewed:** 2026-08-04T12:08:45.365Z

### AI review details

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

- **Mechanism:** collision-safe local symlink setup for agent content and Git hooks

- **Rationale:** This is an unconsented install-time agent-extension and Git-hook setup in a consumer project, creating a real lifecycle/control-surface risk. Source inspection found no concrete malicious chain such as exfiltration, remote code loading, or destructive behavior.

- **Files touched:** package.json, bin/cli.js, \<consumer\>/.agents/skills/\*, \<consumer\>/.agents/constitution, \<consumer\>/.agents/hooks/\*, \<consumer\>/.git/hooks/commit-msg, \<consumer\>/.git/hooks/pre-push

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 91.0%

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

- **Intent class:** Dangerous Capability

- **False-positive risk:** Low

- **Evidence for:** package.json runs postinstall automatically., bin/cli.js postinstall links content into consumer .agents/., bin/cli.js symlinks commit-msg and pre-push into consumer .git/hooks/., Installed constitution/session hook directs AI-agent behavior.

- **Evidence against:** CLI uses only local fs/path operations; no outbound network client., Hook sources enforce local commit/push rules and do not exfiltrate data., Existing non-symlink targets are skipped rather than overwritten.

Source creates an unconsented AI-agent control surface through install-time mutation or a default unauthenticated remote skill channel.

Public source snippet (untrusted):

```javascript
L18: Symlink shared skills/, hooks/, and constitution/ from this package
L19: into <target>/.agents/. Safe to re-run (idempotent); never touches
L20: real (non-symlink) files or directories already there.

L29: Verify a consuming repo's .agents/ wiring and exit non-zero if it is
L30: broken. Checks that the four mandatory files are readable, that no

L110: fs.mkdirSync(path.dirname(destPath), { recursive: true });
L111: fs.symlinkSync(relative, destPath, 'dir');

path = hooks/agent/guard-bash.sh
kind = build_helper
sizeBytes = 1404
magicHex = [redacted]
```

### 11. Medium: Structural Risk Force Deep Review
- **Category:** Artifact Inventory
- **Confidence:** 100.0%

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

### 12. High: Known Malware Source Similarity

- **Confidence:** 97.0%
- **Path:** skills/writing-skills/render-graphs.js
- **Public source:** [View source](<https://unpkg.com/@abblor/agent-os@0.5.1/skills/writing-skills/render-graphs.js>)

Source file is highly similar to a previously finalized malicious package; route for source-aware review.

Public source snippet (untrusted):

```javascript
matchType = normalized_sha256
matchedPackage = @kl-c/matrixos@0.3.65
