ccwasted

CLI tool that analyzes Claude Code conversation logs to find wasted tokens. No AI — pure static analysis of JSONL files.

Install

curl -fsSL https://raw.githubusercontent.com/fyso-dev/ccwasted/main/install.sh | bash

Or with Cargo:

cargo install --git https://github.com/fyso-dev/ccwasted --path ccwasted

Usage

ccwasted                          # last 30 days, grouped by project
ccwasted -d 7                     # last week
ccwasted -d 1                     # today only
ccwasted -o ratio                 # sort by waste ratio
ccwasted --sessions               # per-session breakdown
ccwasted --project-dir /path/to   # filter by project
ccwasted --json                   # JSON output
ccwasted --status                 # one-liner for Claude Code statusLine
ccwasted --rules                  # print optimization rules
ccwasted --inject                 # write rules to ~/.claude/ccwasted-rules.md

What it detects

Analyzer	Detects
Review cycles	Same PR reviewed >2 times
Killed subagents	Agents interrupted mid-work
Context accumulation	Input tokens growing without /compact
Metadata bloat	file-history-snapshots, queue-ops, hooks
File re-reads	Same file read >2 times
Tool errors	Failed tool calls and retries
Missing .claudeignore	Results with node_modules, .git, etc
Broad searches	Grep/Glob without specific path
Self-inflicted diffs	Snapshots triggered by own edits
Model overkill	Opus used for simple Read/Glob/Bash
Repeated ToolSearch	Same tool schema queried multiple times
CLAUDE.md bloat	System prompt >10K tokens

StatusLine integration

Standalone

Add to ~/.claude/settings.json:

{
  "statusLine": {
    "type": "command",
    "command": "ccwasted --status -d 7"
  }
}

Filter by current project

Use --project-dir to show waste only for the active project:

{
  "statusLine": {
    "type": "command",
    "command": "ccwasted --status -d 7 --project-dir \"$PWD\""
  }
}

Add to an existing statusLine script

If you already have a custom statusLine script (Node.js, bash, etc.), append ccwasted output:

# In your statusline script
WASTE=$(ccwasted --status -d 7 --project-dir "$PROJECT_DIR" 2>/dev/null)
echo "$YOUR_LINE | $WASTE"

For Node.js statusLine scripts that receive JSON on stdin:

// Inside your statusline Node.js script
const { execSync } = require("child_process");
const projDir = d.workspace?.project_dir || "";
const dirFlag = projDir ? ` --project-dir ${JSON.stringify(projDir)}` : "";
try {
  const waste = execSync(`ccwasted --status -d 7${dirFlag} 2>/dev/null`, {
    timeout: 3000, encoding: "utf8"
  }).trim();
  if (waste) line += ` | ${waste}`;
} catch(e) {}

Output format

🗑 28M (1%) 💀subagents 10M 36% 🔄reviews 8.6M 30%

└─ total waste tokens (% of all tokens)

Prompt injection

Generate and inject optimization rules based on your actual waste data:

ccwasted --inject   # writes ~/.claude/ccwasted-rules.md + adds @include to CLAUDE.md
ccwasted --rules    # preview rules without writing
