codeburn

codeburn is a skill for Claude Code from akillness/jeo-skills. It costs 209 tokens per session (2,437 once invoked), scanned B, original, no licence file.

A local tool for reading session files from 40 AI coding tools and breaking down token use and dollar cost by task, model, tool, and project. A CLI, TUI, web, or menubar tool is a command-line, text-based, browser, or desktop interface.

In plain words
What is it for?
It helps review token usage and spending across coding-agent sessions, models, tools, and projects.
Why use it?
It gives a way to inspect coding-agent usage and costs from files already stored on your computer. This removes the need to compare session data manually.

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 B, and why

codeburn scanned grade B with 1 finding 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 6d 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.

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.
