Owner/worker delegation skills: astra-sol (Codex) and fable-opus (Claude Code)
Set up
Skills are installed by placing their folder where your agent loads skills.
The download comes from github.com/0alfares082/astra-sol-fable-opus itself, not from our server, so what you get is exactly what its author published.
Install instructions come from the README

synced Oct 22, 2026astra-sol + fable-opus
Two small skills that split one coding task between an owner model and a worker model so the expensive model never types the routine code.
| Skill | Runtime | Owner | Worker |
|---|---|---|---|
astra-sol | Codex | GPT-6 Astra | GPT-5.6 Sol (collaboration.spawn_agent) |
fable-opus | Claude Code | Claude Fable 5.1 | Opus 5 (opus-executor subagent) |
The owner defines scope, writes a six-line work order, delegates ONE bounded unit, keeps doing useful work in parallel, then reviews the actual diff itself. Worker completion is evidence, not approval.
These are the live files from my own setup, published as they are. No claims about token, cost, or speed savings: the skills themselves forbid that. Try one small unit and measure.

Install
Codex (astra-sol)
Copy skills/astra-sol/ into your Codex skills directory (for example ~/.codex/skills/astra-sol/), then ask:
Use $astra-sol to orchestrate this task and delegate the implementation to Sol.
Requires a runtime that exposes collaboration.spawn_agent and offers gpt-5.6-sol. The skill checks both before claiming delegation.
Claude Code (fable-opus)
Copy skills/fable-opus/ into .claude/skills/fable-opus/ and agents/opus-executor.md into .claude/agents/ inside your project, then run /fable-opus with the task. The session model must be Claude Fable 5.1; the worker's model comes from the agent definition (model: opus).
Boundaries
Delegation grants no permission to publish, send messages, spend money, handle credentials, or run destructive commands. If the unit touches one of those gates, the owner stops and asks first.
