Workflow Autonomy

• Fable 5.1 can be steered by prompt to manage long-duration tasks, such as babysitting pull requests until they are merge-ready, by monitoring comments, checks, and CI status without human re-entry.14:39
• The most effective prompting strategy is to define a clear end state—such as "file a PR and merge when green"—and allow the model to continue autonomously rather than checking in at every intermediate step.26:35
• While the speaker warns these workflows are not yet suitable for all production systems, they have successfully automated complex runtime migrations by instructing the model to de-risk with shadow mode, synthetic traffic, and runtime health counters.18:58

Context and Defaults

• The speaker claims fears of hitting a model's "dumb zone" or context limit are overstated, arguing that defaults in current coding harnesses are sufficient and that heavy context monitoring is often wasted effort.35:05
• Old formatting instructions or "anti-slop" rules in configuration files like Claude.md can now overcorrect and suppress model utility as the underlying intelligence improves; the speaker advises starting with a clean config.12:02

Verification

• For high-stakes tasks, the speaker advocates for differential testing and model-to-model verification, such as having a primary agent use an alternate model to audit changes, as standard staging often fails to detect silent correctness bugs like wrong query results.21:01
