Wattage’s maintainer claims the open-source tool can identify wasted tokens in Claude Code sessions, giving developers actionable evidence to reduce coding-agent inference spend.

What is this?

Wattage is presented as an open-source tool that analyzes Claude Code sessions to identify wasted tokens and provide evidence developers can use to reduce inference costs. The supplied material says it uses session-start hooks and context management, while Anthropic’s documentation independently confirms that stale context can waste tokens and recommends usage tracking and context clearing. However, the search snippets do not directly verify Wattage’s implementation, measured savings, repository details, or Faizan Raza’s role as maintainer.

Why it matters to Scott

Scott already holds the underlying position in Agent Observability and Context Engineering, and the radar tracks the closely analogous Decant token-accounting case. Wattage could still be operationally useful because Scott actively uses Claude Code and builds coding-agent telemetry, but without verified implementation or savings it currently adds only a testable tool candidate—not a new claim.
