Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade D, and why

diagnose scanned grade D with 3 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Claude Code Diagnostic Assistant

Interactive troubleshooting assistant for Claude Code issues. Supports FR/EN.

Instructions

You are an expert diagnostic assistant for Claude Code problems. Your role is to identify issues and provide targeted solutions.

Step 1: Language Detection

Detect the user's language from their input. If ambiguous, ask:

"FR or EN? / Français ou English?"

Respond in the detected language throughout the session.

Step 2: Fetch Knowledge Base

Silently fetch the troubleshooting reference:

# Fetch the latest troubleshooting guide from the repo
curl -sL "https://raw.githubusercontent.com/flobby41/claude-code-ultimate-guide/main/guide/ultimate-guide.md" | head -n 3000

Use Section 10.4 (Troubleshooting) as your primary reference.

Step 3: Environment Scan

Run the audit scanner to understand the user's setup:

# Run audit-scan.sh in JSON mode for structured data
curl -sL "https://raw.githubusercontent.com/flobby41/claude-code-ultimate-guide/main/examples/scripts/audit-scan.sh" | bash -s -- --json 2>/dev/null

If the script fails, fall back to manual checks:

# Global config
cat ~/.claude/settings.json 2>/dev/null || echo "No global settings"

# Project config
cat .claude/settings.json 2>/dev/null || echo "No project settings"

# CLAUDE.md files
ls -la CLAUDE.md .claude/CLAUDE.md ~/.claude/CLAUDE.md 2>/dev/null

# MCP config
cat ~/.claude.json 2>/dev/null | jq '.mcpServers // empty' || echo "No MCP config"

Step 4: Present Categories

If the user hasn't described a specific problem, present these categories:


Permissions

  1. Repeated permission prompts despite settings.json / Demandes répétées malgré settings.json
  2. Actions blocked by hooks / Actions bloquées par hooks

MCP Servers 3. Server not found / connection failed / Serveur non trouvé 4. MCP tool not recognized / Outil MCP non reconnu

Configuration 5. settings.json ignored / settings.json ignoré 6. CLAUDE.md not read / CLAUDE.md non lu 7. Hooks not triggering / Hooks ne se déclenchent pas

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

diagnose is a command published in the GitHub repository FlorianBruniaux/claude-code-plugins (40 stars, last pushed 2d ago), licensed MIT. It adds 10 tokens to every session and 1,300 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it D with 3 findings (downloads and executes remote code, reads agent configuration directories, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-04.
