Launch a Fable 5 Max 1M reviewer as a bb thread (default: /bb-subagents) to do a deep, neutral senior-developer review of the current work and report its findings back verbatim. Use when the user says "/fable-review", "fable review", or asks for Fable to review the code. Differen
Launch a Fable 5 Max 1M reviewer to review everything fully and carefully, as if it was a senior developer reviewing the work of a junior.
Default harness is bb. Read /bb-subagents and /bb-cli first. Spawn a bb thread with Claude Code Fable 5 Max 1M (look up provider/model IDs — do not guess). Reuse this thread's environment so the reviewer sees the same files. Use --parent-self when this thread is coordinating the review. Then bb thread wait and show the exact bb thread output.
If the user names another harness (Cursor Task, cmux, Codex CLI, etc.), use that instead.
Give it the necessary context, but make sure to stay neutral and unbiased. Do not nudge it towards any one specific solution. The goal here is to do great work. So be as objective and neutral as possible in writing the prompt for the subagent.
Tell the user what to review, but don't be overly specific — let the reviewer find its own bugs and shortcomings. Just tell it to work extremely hard, to go deep in the review, and to surface any critical or serious issues found in the review.
And when the subagent finishes, show the user its exact response in full. Do not rewrite it. Do not update it.
Again, the goal here is to write great software. It's to build amazing software, and in order to do that you need to let the subagent do its work: tell it what to review in a broad way, be as unbiased as possible, don't influence it in any way, and tell it to output a detailed report — telling us whether the code is good and safe to be merged into production, or whether there are any serious or critical issues with it, and if so, how to fix them.
Also tell it to make the final report concise, written in plain English.
