The format The .SKEL format.
The durable body layout for an AI-native production. Human-readable, LLM-native, openly specified, and designed to outlive every model connected to it.
Because version-controlled stories survive generator churn.
Your production becomes a file you can diff, branch, review, merge, and restore. Models can change every month without becoming the owner of your characters, scenes, shots, continuity, or creative history.
story.skel is the native, human-readable production file: acts → scenes → shots, plus cast, environments, camera intent, continuity, media references, BONE contracts, and extension data.
Lossless by design
SKEL 2.10 is additive and compatibility-minded—older 2.x productions still validate. New capabilities can arrive without forcing existing stories through a migration treadmill.
Opening an AI-generated story and saving it never drops generated depth. Genlock compiles spec/skel.schema.json; .skel.json is a separate portability export.
