What this skill does
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. How It Works Step 1: Classify the Request Decide which operating mode fits the task: Implementation: inspect relevant files first, make the requested change, then run the narrowest meaningful verification. Debugging: reproduce or observe the failure before choosing a fix; keep more than one hypothesis until evidence narrows the cause. Review: lead with actionable findings, each grounded in file, line, behavior, and risk. Prompt adaptation: translate useful workflow intent into Codex-compatible instructions; ignore or rewrite anything that conflicts with active system, developer, safety, filesystem, or tool rules. Provider setup: continue only when the user already has authorized access to the provider and asks for configuration help. …
