claude

performance-analyzer

Lets a coding agent ask what its Claude Code harness costs: hook time, text hooks inject into context, and Hindsight memory's share, with the plugin or settings file behind each cost. A read-only MCP server plus a skill that tells the agent when to call it, how to read the numbers and where each fix goes; needs Bun.

What it installs

Skills (1)

  • harness-cost

    Use when Claude Code feels slow before it answers, sessions start slowly, context is already large before any work, or the user asks which hooks, plugins or Hindsight memory cost time or tokens, wants to trim them, or wants to know whether a hook or plugin change helped.
