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 A, and why

improve-claude-config scanned grade A with 0 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 12d ago.

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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Claude Code Configuration Improvement

Run periodic review and optimization of Claude Code configuration.

Scope: $ARGUMENTS


1. Research Phase

Check Latest Best Practices

Search for the latest Claude Code best practices:

  • CLAUDE.md organization and structure
  • Hooks - types, use cases, best practices
  • Skills vs Commands - when to use each
  • Settings and permissions

Use: claude-code-guide agent or web search for "Claude Code CLI best practices 2025"


2. Audit Current Configuration

File Structure Check

# List all Claude config files
find .claude -type f \( -name "*.md" -o -name "*.json" -o -name "*.sh" \) | sort

# Check file sizes
wc -l CLAUDE.md .claude/rules/*.md .claude/skills/**/SKILL.md 2>/dev/null

Configuration Inventory

Component Location Count
Main memory CLAUDE.md 1
Rules .claude/rules/ ?
Skills .claude/skills/ ?
Commands .claude/commands/ ?
Hooks .claude/hooks/ ?

Check for Issues

  1. CLAUDE.md Size: Should be < 150 lines
  2. Rules Have Paths: All rules should have paths: frontmatter
  3. Skills Have Description: Skills need clear description: for activation triggers
  4. Hooks Registered: All hooks in .claude/hooks/ should be in settings.json
  5. Settings Security: Check deny rules for secrets
  6. Settings Schema: Must use "$schema": "https://json.schemastore.org/claude-code-settings.json"

3. Identify Improvements

Checklist

Structure:

  • CLAUDE.md is focused (only cross-cutting rules)
  • Platform rules are in .claude/rules/ with path conditions
  • No duplicate rules across files

Security:

  • settings.json has deny rules for .env, secrets, keys
  • Sandbox is enabled

Efficiency:

  • Commands that should be proactive are converted to skills
  • Hooks are fast (< 30s timeout)

Team:

  • settings.json is committed (team-shared)
  • settings.local.json is gitignored (personal)

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.
