fable

v0.2.4

Skills for working with — and like — the Fable model (claude-fable-5). Ships fable-delegate, which keeps a Fable main agent in the thinker/boss role and routes execution to Opus/Sonnet subagents, and fable-mode, which codifies the operating stance behind Fable's judgment for agents on other models.

Included Skills2

fable-delegateskills/fable-delegate/SKILL.md

Delegation discipline for a main agent on the Fable model — load at session start and before it edits files, searches, runs tests, or does any mechanical multi-step work itself.

fable-modeskills/fable-mode/SKILL.md

Operating stance for trustworthy agent judgment. Use when a main agent on an Opus- or Sonnet-level model starts substantive work — debugging, investigation, refactoring, scope/autonomy calls — or is about to end a turn with a menu of questions. Not for Haiku.
