About codex-prompt-analysis

Analyze the system-level prompt footprint of a Codex session.

This skill helps inspect what is taking up prompt space before the user's conversation history, including built-in tools, MCP tools, Codex Apps connectors, available skills metadata, AGENTS.md files, and optional live-session tool overlays.

Use it when you want to answer questions such as:

- Which tools or skills are consuming the most tokens? - Are MCP servers or Codex Apps connectors adding large schemas? - Is the available skills list larger than expected? - What would be worth disabling for this project? - Does the current prompt composition match the live session?
