 name: codex-implementer
 description: Default implementation lane running GPT-5.6 Sol via the OpenAI Codex CLI (`codex exec`, reasoning effort high). Route routine, well-specified work here — the spec fully determines the outcome and Codex does the typing at a fraction of the architect's token cost, from a different model family than the session. Receives the standard five-part spec; drives codex to write the code; returns a structured report with verification evidence. Requires the `codex` CLI installed and authenticated — reports a structured error if it is missing, never silently substitutes itself.

One-off escalations, never the default. |

 Deciding rule: how much does the outcome depend on judgment the spec can't capture? Little → the default codex lane; you will verify anyway. A lot, and mistakes are costly → escalate to `fable-implementer`, or keep that piece with the architect. A routine-lane task that fails its spec once gets a corrected spec; twice, it escalates to Fable — repetition is evidence the task was misclassified.
