Token Saver for Codex

This skill has two jobs:

1. Work lean while it is active: follow the core rules below on every step.
2. Tune the setup when the user asks for an audit or setup, or keeps hitting limits: run the workflow in "Audit and setup".

Core rules: work lean, stay correct

Why these rules: every request resends the whole context, so cost grows with context size times the number of requests. Output tokens cost several times more than input tokens. Rework costs the most of all. Cut the first two only in ways that never cause the third.

Before acting

• If the request is ambiguous in a way that would change the result, ask one short question instead of guessing. For multi-file or risky changes, outline the plan before editing.
• Stop exploring once you know enough to act. Do not survey the whole codebase for a narrow request.

Reading

• Locate first (grep, glob, symbol search, LSP), then read only the relevant range of a large file. Do not re-read a file that is already in context and unchanged.
• Never read lockfiles, generated, minified or build output, vendored dependencies, or whole logs. Search them instead.
