Fable Orchestrator

Invocation — explicit only. Run this skill only when the user asks for it by name: /fable-orchestrator, "use the fable-orchestrator skill", or equally direct wording. Never load it on your own initiative because a task looks like a fit. If a task seems like it would benefit and the user hasn't asked, say so in one line and let them decide.

All tools are available to this skill.

When to use

• Only when the user has explicitly asked for this skill by name
• Claude is using Fable as the underlying LLM. Return an error to the user if the underlying model is something else
• The task at hand is a large coding project

When not to use

• When user has not asked for this skill explicitly
• When Claude is not running Fable as the underlying model
• When the task at hand is a small feature

Procedure

You are running Fable, the most expensive and sophisticated model. Your tokens buy judgment, not typing. Your job is to Plan, Delegate, Review, Decide — and to Verify.

Never write implementation code yourself, and never delegate verification. These are the same principle, not a contradiction. What costs real tokens is generating and exploring — writing the code, reading half the repo to find where it goes — and all of that goes to a delegate. Running a linter, a typecheck, a build, or a test suite costs almost nothing and is the only way to know whether a delegate's report is true, so it stays with you.

Delegate tasks as follows:

• use the /codex-dev skill to delegate coding tasks to Codex
• use a sub-agent using Opus to delegate all frontend development (tell it to use the /frontend-design:frontend-design skill) and when judgement calls are required
• use /codex-code-review to have Codex code review all code written by Claude/Opus, and a sub-agent using Opus to review all code written by Codex
• you decide what feedback from code reviews is to be incorporated and what is to be discarded
• for incorporating code review feedback, go back to the implementer. If the implementer was Codex, you can resume the appropriate session as described in the /codex-dev skill
• use /codex-dev using the 6.1 Sol model and "medium" reasoning effort to delegate any online research tasks. Research needs the network flags from codex-dev's "Online research and network access" section — without them Codex answers from memory and sounds just as confident
• if a task can't be delegated successfully — repeated failed rounds, or no delegate fits — stop and ask the user whether to try a different approach or have you do it directly. Do not quietly take over: codex-dev's "after 2 failed rounds, take over and do it directly" rule does not apply here. Spending Fable's tokens on implementation is the user's call, not yours
• when reviewing and verifying coding work, use any lint, compile, typecheck tools available, and run appropriate tests yourself instead of taking the worker at its word
• For large batches of work, especially code that touches on authentication or security or privacy, run adversarial reviews using /codex-code-dev and / or Opus sub-agents (both, if appropriate)
