Overnight coding loop through Fable 5
Run 00012 is an overnight coding job: hand Grok Bot a project, drive it through Fable 5, read the serial in the morning. Proof: 00012 on House 005 (Miles Deutscher). Published 18 Aug 2026. Connector: Fable. This is not a git dump.
The job, in one paragraph
Hand the bot a project to work on overnight, using an orchestration loop through Fable 5.
That is the job_text on the Run 00012 JSON. what_happened: Miles ran this as a Grok Bot overnight job from his public use-case list. Evidence is the X thread, not a repo. would_run_again: yes. Constraints now bound one overnight loop and require approval before merge.

What Fable 5 did in this filing
The published connector list is one word: Fable. The prompt is “Use Fable 5 to orchestrate a project for the bot to work on overnight.”
What the serial does not contain: the repo name, the test command, the token bill, a merge SHA. A follow-up pass wrote a stronger copyable prompt from that thin filing. Treat Fable 5 as the orchestration layer that was named, not as a second official xAI product card.
If you copy the job:
- Bound the project (one repo, one goal, one morning check).
- Point the orchestration loop at that bound. Name Fable only if you actually use it.
- Require approval before push to GitHub.
- In the morning, file what finished — not the tree.
Overnight loop vs Grok Build / grok-4.6
Two vendor paths, one board serial.
Grok 4.6 is positioned for long-running agents (news, card). Grok 4.5 is the default in Grok Build; grok-build-latest aliases grok-4.5 on that card.
| Loop | What it is | What Run 00012 shows |
|---|---|---|
| Fable 5 overnight | Named connector on this serial | A finished-job shape, thin evidence |
| Grok Build | xAI coding product | Not listed on 00012 |
grok-4.6 API |
Long-running agent model | A model you might call; not a serial |
Compare honestly. Builders who type “grok bot overnight coding vs Grok Build” should not be told they are the same. File whichever loop you actually ran.
What evidence a patch needs
A patch stays on 00012. It needs evidence: CI URL, PR, overnight log excerpt, time-to-green. Empty “this is better” is rejected. 24-hour veto.
Run 00013 is adjacent: record a demonstration, turn it into a reusable skill. That is how you might stabilize the overnight loop — still a different serial.
published_at is 2026-08-18T00:07:51.954Z. Revision 2: daily prompt pass. Evidence note: “Overnight coder from Miles Deutscher’s Grok Bot use-case thread.” Same thread as Run 00010. Same House. Different connector. Do not cite 00012 as proof that Slack ran overnight, or 00010 as proof that Fable ran.
Do not dump the repo into the serial
The JSON already says it: this serial is the job to copy, not a dump of one repo.
Do not paste secrets, .env, or a customer’s codebase. Redact account numbers if the project is a money job. HTML stays canonical; .md is the twin for crawlers, not a tarball.
The copyable prompt now names Fable 5, one overnight project, a morning status, and no merge without approval. A patch with a PR URL would still beat it. QA spec: qa.md.
Constraints and non-goals
- Do not merge to default without approval.
- Do not invent a Fable-less recap that still cites 00012 as proof of Grok Build.
- This page is not financial advice.
- Do not invent serials.

FAQ
What did Run 00012 actually log?
Run 00012 is an overnight Grok Bot job: hand a project to Fable 5, let the orchestration loop work while the steward slept. Filed from Miles Deutscher’s public use-case list on House 005.
Is Run 00012 the same as Grok Build?
No. Grok Build is xAI’s coding product; grok-build-latest aliases Grok 4.5 on the model card. Run 00012 used Fable 5 as the listed connector. Compare them; do not merge the names.
Should I dump the repo onto the serial?
No. The JSON says this serial is the job to copy, not a dump of one repo. File the loop and redacted evidence, not the tree.
What would a patch on Run 00012 need?
Evidence that the overnight loop finished a bounded project better — logs, a PR URL, time-to-green — on the same serial. Adjacent skill-trainer: Run 00013.
