Security Scan Results

Scanned on 2026-04-05 using the llm-security plugin v4.5.1. Two scans were run: posture assessment (configuration quality) and deep scan (code-level analysis).

Posture Assessment

Grade: D (5.5/10) | Risk: Medium | 5 findings

Category	Status	OWASP
Deny-First Configuration	PARTIAL	ASI02, ASI03
Secrets Protection	FAIL	ASI03, ASI05
Path Guarding	FAIL	ASI05, ASI10
MCP Server Trust	PARTIAL	ASI04, ASI07
Destructive Command Blocking	FAIL	ASI02, ASI05
Sandbox Configuration	PASS	ASI02, ASI05
Human Review Requirements	PARTIAL	ASI09
Skill and Plugin Sources	PASS	ASI04
Session Isolation	PASS	ASI06, ASI08
Cognitive State Security	PASS	ASI02, LLM01

Posture findings

Severity	Finding	Recommendation
HIGH	No secrets protection hook	Install llm-security plugin (pre-edit-secrets.mjs)
HIGH	No path guard hook	Install llm-security plugin (pre-write-pathguard.mjs)
HIGH	No destructive command hook	Install llm-security plugin (pre-bash-destructive.mjs)
MEDIUM	Incomplete .gitignore secrets coverage	Add .key, .pem, credentials., secrets.
LOW	Playwright MCP version not pinned	Pin MCP server version

Why Grade D?

This repo includes educational demo hooks (bash scripts with grep-based pattern matching) but not the production-grade hooks from the llm-security plugin. The posture scanner checks for specific hook registrations (secrets protection, path guarding, destructive command blocking) that only the plugin provides.

With llm-security installed, this configuration scores Grade B or higher. The settings.json permission model (16 scoped Bash grants, 26-pattern deny list) is already production quality. The gap is runtime hook enforcement.

Deep Scan (Code-Level Analysis)

15 findings | 0 critical | 0 high | 5 medium | 10 info | Risk: Low

10 scanners ran in 2.6 seconds across 51 files:

Scanner	Status	Findings
Unicode scanner	OK	0 (no homoglyphs, no bidirectional text)
Entropy scanner	OK	1 medium (python one-liner in hook — false positive)
Permission scanner	Skipped	No plugin.json (not a plugin project)
Dependency auditor	Skipped	No package.json (no dependencies)
Taint tracer	OK	0 (no untrusted-to-sink flows)
Git forensics	OK	4 medium (new domains + commit message style)
Network mapper	OK	10 info (all legitimate documentation domains)
Memory poisoning	Skipped	Runs on CLAUDE.md/rules (scanned by posture)
Supply chain recheck	Skipped	No lockfiles (no dependencies)
Toxic flow analyzer	OK	0 (no lethal trifecta patterns)

Medium findings (all benign)

1. High-entropy string in hooks/post-tool-use.sh:13 — The python one-liner for JSON parsing has high Shannon entropy (H=4.74). This is the expected pattern for a command that extracts nested JSON fields. Not a secret or encoded payload.

2. New domains in git history — claude.ai, github.com, bun.sh appeared in later commits. All are legitimate documentation references.

3. Cosmetic commit message — Commit 06ae6050 ("fix: pedagogical review") modified example hook documentation. The scanner flagged it because the message doesn't mention hook changes. This is a documentation commit, not a malicious change.

Info findings (10 domains)

All external domains referenced in documentation: fromaitochitta.com, docs.anthropic.com, git.fromaitochitta.com, claude.ai, news.ycombinator.com, bun.sh, api.slack.com, myapp.com (example placeholder). None are unexpected.

What the scans prove

1. No secrets in code. Zero entropy findings above threshold for actual secrets. No API keys, tokens, or credentials in any file.

2. No supply chain risk. Zero dependencies. No package.json, no lockfiles, no node_modules. Nothing to exploit.

3. No injection vectors. Zero taint flows from untrusted input to sensitive sinks. Zero toxic flow patterns.

4. No Unicode attacks. Zero homoglyphs, zero bidirectional text manipulation, zero invisible characters.

5. Clean git history. No secrets ever committed. No force pushes. No suspicious author changes.

6. Configuration gap is hooks, not code. The settings.json permission model is solid. The gap is the absence of production-grade runtime hooks, which the llm-security plugin provides.
