BF mobile-development

Build, test, sign, and ship mobile apps across iOS, Android, Flutter, and React Native — project scaffolding, builds and code signing, device and emulator testing, store submission (App Store and Play Store), app lifecycle and backgrounding, offline and sync, and mobile-specific testing. Use when the task involves creating, building, testing, or shipping a mobile app for iOS or Android, or reasoning about mobile behavior such as background execution, push notifications, offline storage, and data sync. Do not use for web frontend work (that is frontend-engineering), backend services and APIs (that is backend-engineering), or desktop and web platform targets outside the iOS and Android scope.

How to improve

  1. The text references files that are not there: add them or drop the references.
For the model run — optional
  • A spec.yaml with trigger phrases and assertions — a behaviour contract for CI; `skilltest init` writes a template.

Will not run. References files that are not bundled: ../frontend-engineering/SKILL.md, ../backend-engineering/SKILL.md, ../release-engineering/SKILL.md
  • 0Tools and files. 5 referenced file(s) missing: ../frontend-engineering/SKILL.md, ../backend-engineering/SKILL.md, ../release-engineering/SKILL.md
  • 0Result and completion. Does not say what the result is
  • 0Inputs and preconditions. Does not say what the process needs to start
  • 0Progress reporting. Says nothing while it works
  • 50When it triggers. No condition that starts the skill
  • 50Failures and branches. 0 branches, has a failure section
  • 100Steps. 40 steps
  • 100Consistency. Name and required fields are in place
  • 100Execution cost. Instruction body is 3075 tokens
  • 100Running it twice. Mutating operations check current state

Everything here is measured from the skill text rather than judged by a model, so the numbers are checkable. A parameter weighs more when it is a more common reason for the process to stall.

Quality signals

  • +5Description has no quoted example phrases that should trigger the skill
  • +3Output format is not stated: the model decides each time
  • +2Single-language instructions
  • +4Description says when NOT to use the skill
  • +3Description length 699: enough signal without eating the budget
  • +4Structure: 15 headings
  • +3Step-by-step instructions: 40 items
  • +4Has examples (0 code blocks)
  • +4Reference files are cited in the instructions (4 of 4)
  • +1License stated

Quality base 70; lint remarks subtract, signals add up to 100. Result: 81.
