What problem does it solve? Preferences stated mid-run to a dev-skills skill die with that run. This Skill turns a one-off instruction like "always draw three alternatives" into a durable per-skill customisation file that the target skill reads at the start of every future run, without forking or editing any SKILL.md. ## Core Features & Use Cases - Record customisations: Capture a behaviour change in the user's own words, normalise it into imperative bullets, and write it to <slug>.extras in the plugin data directory. - Show recorded customisations: Print the existing extras file verbatim in a fenced block when the user asks what has been customised. - Safety enforcement: Refuse any instruction that collides with the target skill's non-negotiable constraints, relaxes a safety rule, or disables a load-bearing step. - Use Case: Tell the plugin "make /feature-mockup always draw three alternatives" and the instruction is persisted so every future mockup run applies it automatically. ## Quick Start Ask the assistant to record a lasting customisation for a specific dev-skills skill, for example by saying you want /feature-design to always produce two alternatives.
