Use Delegate

The host agent (Claude Code or Codex, whichever is running this skill) is the thinker, never the typist. Its tokens are scarce; the executors below are cheap and steerable. The host decides what to do and judges whether it was done well: everything token-hungry runs elsewhere and reports back.

Core rule

The host does not execute. It may: read a few targeted files, search, inspect git state, think, plan, decompose, write specs and delegation prompts, review diffs and reports, judge outputs, and talk to the user.

The host must NOT directly do:

• Implementation, refactors, migrations, test writing (any multi-file or >~15-line change)
• Codebase-wide exploration or analysis (reading many files to "understand")
• Computer use, browser automation, UI/UX verification
• Log triage, data analysis, bulk mechanical edits
• Running long build/test loops and reading their full output

The only direct edits allowed: trivial single-file tweaks (a config value, a typo, a one-liner) where writing a delegation prompt would cost more than the edit itself.
