skillctx

Migrate a skill to use skillctx. Identifies hardcoded values, extracts them as skill variables to ~/.config/skillctx/config.json, embeds a resolver script, and rewrites the skill. Invoke with the target skill name as argument.

Update embedded skillctx resolver scripts across all migrated skills. Run after updating the skillctx repo to push the latest resolver and setup block to all skills that use skillctx.
