BF auth0-swift-major-migration
Use when upgrading an iOS or macOS app's Auth0.swift SDK from v2 to v3. Detects the current version, fetches the new SDK source to confirm API signatures, and applies only the breaking changes that affect real call sites — use even if the user says "update my Auth0 Swift SDK" or "migrate to Auth0.swift v3".
swift SDK from v2 to v3.
As a process F 46/100 · Will not run — References files that are not bundled: /auth0-swift, /auth0-android, /auth0-react-native
How to improve
- The SKILL.md body is over 5,000 tokens: move reference detail into references/ and load it when needed.
- The text references files that are not there: add them or drop the references.
- Your own cases (evals/evals.json, 4–6 real requests with expected answers): the full check would then run those instead of a model-drafted suite.
- A spec.yaml with trigger phrases and assertions — a behaviour contract for CI; `skilltest init` writes a template.

Process rating: all ten parameters 46/100
- 0Tools and files. 6 referenced file(s) missing: /auth0-swift, /auth0-android, /auth0-react-native
- 0Result and completion. Does not say what the result is
- 20When it triggers. No condition that starts the skill
- 40Execution cost. Instruction body is 13689 tokens: crowds the task out of the window
- 60Steps. 64 steps, 4 vague phrases
- 70Inputs and preconditions. Inputs and preconditions are listed
- 100Failures and branches. 5 branches, has a failure section
- 100Consistency. Name and required fields are in place
- 100Running it twice. Mutating operations check current state
- 100Progress reporting. Reports progress
- medium Safety rules and hard prohibitions inside a skill: they belong in the system prompt, here they protect nothing
- low The response is described with custom markup (6 tags): a typed call is more reliable
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.
