ccoverage

Know what's actually working in your Claude Code setup — and what's dead weight.

The Problem

Claude Code configs grow organically. You add skills, MCP servers, hooks, and CLAUDE.md files as you go. Over time, some become outdated, redundant, or forgotten. Nobody knows what's actually used — until something breaks or your context window fills up with irrelevant instructions.

What ccoverage Does

ccoverage scans your repo's Claude Code configuration and joins it against real session history to classify each item:

• Active — used recently and frequently
• Underused — seen in sessions, but below your usage threshold
• Dormant — configured but never appeared in any session

This is session-backed analysis, not just static file detection. It checks what you actually use.

Quick Start

Homebrew (macOS/Linux)

brew install ShuhaoZQGG/tap/ccoverage

Go

go install github.com/ShuhaoZQGG/ccoverage@latest

Download from Releases

Grab a prebuilt binary from GitHub Releases for Linux, macOS, or Windows (amd64/arm64).

Usage

scan — See what's configured

ccoverage scan --target . --format text

Lists all detected configuration items without checking session data.

report — Full coverage analysis

ccoverage report --target . --lookback-days 30 --format json

Scans config, matches against session history, and classifies each item.

Filter by status or config type:

ccoverage report --status Dormant
ccoverage report --type MCP --format json
ccoverage report --status Dormant,Underused --format md

init — Install the SessionEnd hook

ccoverage init --target ~/Project/MyRepo

Adds a SessionEnd hook to the repo's .claude/settings.json so you get a one-line coverage summary after every Claude Code session.

summary — One-line summary (hook use)

ccoverage summary --target .

Outputs a compact summary line. Designed to run as a SessionEnd hook.

Config Types Detected

How It Works

1. Scan — Reads .claude/settings.json, CLAUDE.md files, and project config to build a manifest of all configuration items
2. Match — Locates session JSONL files and parses tool calls, content blocks, and file paths to find evidence of each config item being used
3. Classify — Compares usage counts against the threshold (default: 2) to assign Active, Underused, or Dormant status

CI Integration

Use --error-on-match to fail your build when dormant config is detected:

# .github/workflows/config-hygiene.yml
- name: Check for dormant config
  run: |
    go install github.com/ShuhaoZQGG/ccoverage@latest
    ccoverage report --status Dormant --error-on-match

Exit code 1 means matches were found. Clean up your config or adjust the filter.

SessionEnd Hook

Run ccoverage init on your repo to automatically get a coverage summary after every Claude Code session:

ccoverage init --target .

This installs a hook that runs ccoverage summary at session end, showing something like:

ccoverage: 12 items — 8 Active, 2 Underused, 2 Dormant

Output Formats

Text (default) — human-readable table for terminal use

ccoverage report --format text

JSON — machine-readable for scripting and CI

ccoverage report --format json

Markdown — for documentation or PR comments

ccoverage report --format md

Menubar App

ccoverage includes a companion macOS menubar app (in menubar/) built with Swift that displays your latest coverage summary at a glance.

Download (recommended)

Download CCoverage.dmg from the latest release, open it, and drag CCoverage to Applications.

The app is signed and notarized by Apple — no Gatekeeper warnings.

Prerequisites

• macOS 14 (Sonoma) or later
• Swift 5.9+
• ccoverage CLI binary in your PATH

Build & Run

cd menubar
swift build                # debug build
# swift build -c release   # optimized build

# run the app
.build/arm64-apple-macosx/debug/CCoverageMenuBar

The app runs as a menubar-only app — it won't appear in the Dock, just in the menu bar.
