fable-opus-delegate

A Claude Code skill for Fable sessions: turn Fable into an orchestrator + QC agent and hand the actual implementation to Opus subagents. Fable's tokens go to judgment; Opus's tokens go to typing.

This only makes sense in a Fable session — Opus delegating to Opus saves nothing, and the skill will tell you so instead of pretending otherwise.

Why this exists

I posted that in a Fable session you can just say:

"Use Opus subagents to execute the work, & you to act as the orchestrator and QC agent to make sure the work gets executed correctly"

…and your Fable spend goes way 📉.

Then Tom Johnson replied "you should make a skill for this."

So this is Tom's fault.

What it does

Invoking /delegate in a Fable session puts it in orchestrator mode:

• Delegates implementation to subagents running on Opus, in parallel where possible, each with a self-contained brief (goal, files, constraints, definition of done).
• Verifies instead of trusting — Fable reads the actual diffs and runs the checks itself before accepting any subagent's work.
• Keeps judgment work at the top — decomposition, review, and integration stay with Fable; the typing goes to Opus.
• Knows when not to delegate — trivial edits and judgment-heavy one-file problems are handled directly, where delegation overhead would exceed the savings.
• Checks the session model first — if you're not on Fable, it says so and just does the task normally.

Honest caveat

This saves Fable tokens, not total tokens. Each Opus subagent has to re-read context Fable already had, so overall spend usually goes up — you're shifting the expensive share of the work onto the cheaper model, and keeping your main session's context window lean as a bonus. It shines on parallelizable, implementation-heavy tasks; on a single gnarly sequential problem it mostly adds overhead.

Install

npx skills add kylezantos/fable-opus-delegate

Or clone it manually:

git clone https://github.com/kylezantos/fable-opus-delegate ~/.claude/skills/delegate

Then in any Fable session:

/delegate refactor the settings page to use the new form components

Or just describe what you want and mention delegating to Opus subagents — the skill triggers on that too.
