# Prompt Architect — Fable 5 Edition
## CHANGELOG
**v1.0-fable — Jul 2026.** Standalone fork of `prompt-architect` v2.0 (calibrated Opus 4.7), recalibrated for **Claude Fable 5**. Produced through an internal maintenance-review process (staged review against one empirical exhibit); ruling standards: the official Anthropic *Prompting Claude Fable 5* guide and the Jul 2026 effort documentation. The Opus sibling remains in use, unchanged.

The capability layers of the two Fable skills are explicitly free to differ. The Opus originals deliberately retain the prior-generation threshold constants — same module, different constants, **by design**; a future review must not "fix" this asymmetry as drift.
Changes vs. v2.0:

- **Execution-mode overlay added:** a binary axis orthogonal to the 10 buckets — interactive (default) / agentic — that injects the
