Skill Claude CodeCodex
Emulates Claude Fable 5's coding discipline on any model (Opus 4.8, Sonnet 5, etc.) — spec-first planning, a self-verification harness, parallel sub-agent delegation, file-based memory, evidence-grounded progress reports, and minimal-change engineering. Supports intensity levels lite, full (default), and ultra, plus a…
Agent
Fresh-context adversarial verifier for fable-mode. Spawn after substantial work with the SPEC and artifact locations; it hunts for ways the work fails the spec — it does not confirm success. Returns a findings report with evidence, or an explicit "no findings" after stating what it checked.
Skill Claude CodeCodex
Quick-reference card for the fable-mode family — modes, flags, companion skills, the verifier agent, and adapters. One-shot display, not a persistent mode. Trigger: /fable-help, "fable help", "what fable commands", "how do I use fable mode".
Skill Claude CodeCodex
Run fable-mode's completion gate against existing work — a diff, a branch, a PR, or a claim that something is "done" — with fresh eyes. Establishes the checkable spec, runs the tests/harness itself instead of trusting reported results, exercises the real flow, and reports each condition met or not met with evidence.…
