.claude/commands/stats.md

stats is a command for Claude Code from mylee04/who-ran-what. It costs 6 tokens per session (401 once invoked), scanned A, original, MIT.

A command that analyses Claude Code usage, including tool activity, agents, projects, and daily, weekly, or monthly patterns. It can also identify unused agents and skills.

In plain words
What is it for?
Viewing usage statistics, comparing agent activity, checking project activity, studying time-based trends, and finding unused configuration.
Why use it?
It turns raw session records into an overview of how the coding agent is being used.

Command for Claude Code

Written for Claude Code: installed under .claude/. Also seen: reads .claude/ paths; mentions Claude Code.

This is mylee04/who-ran-what's own configuration. It tells Claude Code how to work on who-ran-what itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything who-ran-what configures →

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is ./bin/who-ran-what month | grep -A 20 "Top Tools".

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

stats 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 10d 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.

What it actually says

Usage Statistics

What This Command Does

Provides in-depth analysis of Claude Code usage patterns.

Analysis Areas

1. Tool Usage Breakdown

# Show all tools used, sorted by frequency
./bin/who-ran-what month | grep -A 20 "Top Tools"

2. Agent Efficiency

Compare agent usage patterns:

  • Which agents are used most?
  • Are any agents underutilized?
  • Usage trends over time

3. Project Activity

# List all projects with Claude data
./bin/who-ran-what projects

# Check specific project
./bin/who-ran-what project

4. Time-Based Analysis

# Daily activity
./bin/who-ran-what today

# Weekly trends
./bin/who-ran-what week

# Monthly overview
./bin/who-ran-what month

5. Cleanup Recommendations

# Find unused agents and skills
./bin/who-ran-what clean

Insights to Look For

  1. High Bash usage - Might benefit from more specialized tools
  2. Low agent usage - Could leverage agents more for complex tasks
  3. Unused skills - Consider removing or using configured skills
  4. Project patterns - Identify most active projects

Custom Analysis

For deeper analysis, the raw session data is in:

~/.claude/projects/*/sessions/*.jsonl

Use jq to extract specific patterns:

# Count tool calls by type
jq -r 'select(.message.content) | .message.content[] | select(.type=="tool_use") | .name' \
    ~/.claude/projects/*/sessions/*.jsonl | sort | uniq -c | sort -rn
Changes

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.
