82%Weight 40%Scale 1-5Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
A strong, highly actionable body: complete executable Swift covering the whole central/peripheral lifecycle with proper state gating, flow-controlled writes, and a review checklist. The main deductions are mild — overlapping mistakes/checklist tables, stubbed reconnect handling, and a main file dense enough that more advanced material could move to the existing reference.
Suggestions
Merge or differentiate the Common Mistakes table and Review Checklist (they repeat retention, nil-scan, and write-type guidance) to reclaim tokens without losing coverage.
Implement the reconnect path concretely (e.g., connect(peripheral:) retry with delay in didDisconnectPeripheral) and check the error parameter in didUpdateValueFor/didUpdateNotificationStateFor to make error-recovery feedback loops explicit.
Consider moving part of the state-restoration code (peripheral-manager restoration in particular) into references/ble-patterns.md so SKILL.md reads more like an overview with pointers.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is efficient and assumes competence — no basic-concept explanations, just executable delegate code and tight tables. Minor trimmable fat remains: the Common Mistakes table and Review Checklist substantially overlap (e.g., retention, nil scans, and write-type checks each appear twice), and the state-restoration code blocks are lengthy for an advanced topic. This sits between the lean anchor 5 and the efficient anchor 4, noticeably above the midpoint. | 4 / 5 |
Actionability | Fully executable, copy-paste-ready Swift: complete CBCentralManager/CBPeripheralManager classes, full delegate implementations for discovery, reads (including a working heart-rate parser), writes with type selection and maximumWriteValueLength gating, notifications, advertising, and state restoration. Specific examples cover the common cases exactly as the anchor-5 example requires. | 5 / 5 |
Workflow Clarity | The central-role sequence is clearly driven by delegate-callback gating (.poweredOn → scan → didDiscover → connect → didConnect → discoverServices → characteristics → read/notify/write) with error callbacks and a review checklist serving as validation. Minor validation gaps remain: reconnection is a comment stub ('optionally reconnect'), and error parameters in didUpdateValueFor/didUpdateNotificationStateFor are discarded by the guards, so error-recovery feedback loops are not fully explicit. | 4 / 5 |
Progressive Disclosure | Good structure with a verified, well-signaled one-level-deep reference (references/ble-patterns.md) that genuinely holds overflow content (SwiftUI integration, reconnection, L2CAP), plus a table of contents. It falls short of anchor 5 because the main file is a dense ~427-line manual rather than an overview-plus-pointers: substantial advanced material (state restoration, full peripheral advertising) sits inline where the anchor-5 pattern would split a few more key examples into the reference file. | 4 / 5 |
