Codex Fable5

Overview

Codex Fable5 applies Fable-inspired operating habits to Codex-style coding work. It emphasizes reading the workspace before acting, preserving active system and safety instructions, tracking goals and review findings, grounding claims in evidence, and verifying before saying work is complete. This skill is adapted from the community project at baskduf/FableCodex.

It does not clone, unlock, or replace any Fable-family model. Treat it as workflow discipline, not as proof of provider identity, hidden capability, model access, or context-window parity.

When to Use This Skill

• Use when the user asks Codex to work in a Fable-like, Fable5, VFF, evidence-first, or strict verification style.
• Use when converting Claude, Anthropic, or Fable-flavored prompt guidance into Codex-safe project instructions.
• Use when a coding task needs explicit goal tracking, investigation before edits, review-finding closure, or final verification gates.
• Use when setting up optional FableCodex plugin workflows for users who want reusable local goal and findings ledgers.
