Autonomous Coding Agent Blueprint
Claude 5 Mythos + Fable skill — Agentic Workflows. Optimised for Claude 5 Mythos (reasoning) and Claude 5 Fable (action / tool use), and backward-compatible with Claude Sonnet 4.5 and Opus 4.
TL;DR
Ship a coding agent that behaves like a careful junior: reads the ticket, writes a plan comment, edits in a branch, runs tests, iterates on failures, opens a PR with a self-review checklist, and stops on destructive commands.
When to use this skill
- You are working with Claude 5 Mythos or Fable (or a downstream vendor exposing them).
- The task benefits from — do not use for tasks a smaller model handles cheaply.
