Implement Spec with Codex
Run implement-spec exactly — same loop, same
gates, same maintenance checkpoints — but Codex writes the code. Invoking this
skill IS the explicit ask that authorizes codex exec delegation under the
codex skill.
Role split
- Codex implements — whenever possible. Default every implementation pass
to a
codex exec, sliced sharp and prompted per the codex skill (prompt
blocks, sandbox choice, exec liveness). Run independent slices as concurrent
execs in separate worktrees, exactly where implement-spec would fan out
subagents.
- You orchestrate and review. The spec loop stays yours: pick the next
slice, reconcile plan with code, author each prompt end-to-end, integrate
diffs, run the gates, refactor-clean and review the merged tree, commit,
update the handoff, run maintenance checkpoints. None of that delegates.
Keep a pass yourself only when slicing it sharply would cost more than doing
it — tiny fixups, plan reconciliation, integration conflicts.
Rules
- You own every result: read the full diff and run the verification yourself.
"Codex says it's done" is never done.
- Visual results carry implement-spec's two extra proofs (production-route
pixel diff + unprimed critique) with double force here: a sandboxed Codex
never saw its change render, so a pass that misses the production render
path entirely arrives looking fully "verified".
- A sandboxed Codex ships code it never saw run — browser-verify every visual
slice yourself and budget fix rounds. Send a red gate back as a resumed
follow-up with the failing evidence; fix it yourself only when that's
smaller than re-prompting.
- Commit hygiene stays yours: review the change list of the merged tree
before every commit, exactly as implement-spec demands of the integrating
reviewer.
