## What it does

The skill executes `npx -y codeburn@0.9.27 today` via Bash. CodeBurn scans session logs stored on the local machine by coding assistants such as Claude Code, Codex, and Cursor. From those logs, it extracts token consumption and pricing figures for the current day.

The agent formats the output into at most five bullet points. This includes the total amount spent, the priciest models, the most expensive projects, and noticeable anomalies. It also suggests one specific step to reduce token usage, relying strictly on the extracted numbers.

Running this skill requires `npx` available in the local path, as it pulls CodeBurn on the fly to inspect the logs.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add getagentseal/codeburn --skill cost -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/cost/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/cost/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add getagentseal/codeburn --skill cost -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/cost/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add getagentseal/codeburn --skill cost -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/cost/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install getagentseal/codeburn cost
```

2. **Manually: put the files in place**
- File: `.github/skills/cost/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add getagentseal/codeburn --skill cost -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/getagentseal/codeburn --path plugins/codeburn/skills/cost
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/cost/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add getagentseal/codeburn --skill cost -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

## When to use it
- check total spending across AI coding tools for the day
- identify the most expensive model or project
- catch unusual spikes in token consumption
- find an actionable recommendation to spend less on AI tools

## Example prompts
- How much did my AI coding tools cost today?
- Show token spending by model and project for today
- Which project cost the most today?

Today's AI coding usage, from CodeBurn. It reads the session logs that Claude Code, Codex, Cursor and other tools keep on this machine:

!`npx -y codeburn@0.9.27 today`

Summarize this in at most five short bullets: the total cost, the models and projects that cost the most, anything unusual, and one concrete way to spend less. Use only the numbers above.
```
