Claude Code + Fable 5
A stronger model needs a stronger workbench
Claude Code is useful inside real repositories. Fable 5 expands what people expect from Claude. Clef's product opportunity is to make those runs easier to brief, observe, review, and reuse.
Quick summary
- Use Claude Code for local project execution.
- Use Fable 5 for frontier planning, synthesis, and reasoning-heavy phases.
- Use Clef to keep the workflow legible across runs.
The problem is not prompt length
Long agent work breaks down when the goal, source material, constraints, tests, and final review are scattered across chat turns. The stronger the model, the more important the control surface becomes.
A practical run shape
Start with a work brief, attach source cards, choose a model route, run the task, capture evidence, and pause at a review gate before deployment, merge, or publication.
What Clef should sell
Clef sells the organized workflow: local context, route choice, task history, review gates, and reusable workflow packs for people already using frontier tools.
Turn the search into a workflow
Clef is testing a product layer for people who want frontier models to produce reviewable work, not just impressive chat answers.

Can this work for Codex too?
