Gates (review workflow)

Complete in order; do not skip ahead.

  1. Anchor scope — Pass when: every reviewed file is listed as a repo-relative .swift path (or the review explicitly states “none opened / N/A” with reason).
  2. Reference before critique — Pass when: for any non-trivial body, modifier chain, or wrapper-ownership question, you have opened the matching references/*.md row from the table above or you state “not needed” with one line why.
  3. Evidence-bound findings — Pass when: each substantive issue includes [FILE:LINE] (or a bounded line range) before recommendations; symbols/snippets may supplement but not replace the location anchor; no finding that rests only on “typical SwiftUI” without pointing at this code.

Review Checklist

  • View body under 10 composed elements (extract subviews)
  • Modifiers in correct order (padding before background)
  • @StateObject for view-owned objects, @ObservedObject for passed objects
  • @Bindable used for two-way bindings to @Observable (iOS 17+)
  • LazyVStack/LazyHStack for scrolling lists with 50+ items
  • No AnyView (use @ViewBuilder or generics instead)
  • ForEach uses stable Identifiable IDs (not array indices)
  • All images/icons have accessibilityLabel
  • Custom controls have accessibilityAddTraits(.isButton)
  • Dynamic Type supported (no fixed font sizes)
  • .task modifier for async work (not onAppear + Task)

When to Load References

  • Complex view bodies or modifier chains -> view-composition.md
  • Property wrapper usage (@State, @Observable) -> state-management.md
  • List performance or view identity issues -> performance.md
  • VoiceOver or accessibility implementation -> accessibility.md

Review Questions

  1. Could this large view body be split into smaller, reusable Views?
  2. Is modifier order intentional? (padding -> background -> frame)
  3. Is @StateObject/@ObservedObject usage correct for ownership?
  4. Could LazyVStack improve this ScrollView's performance?
  5. Would VoiceOver users understand this interface?

同一仓库的技能

Use when you need to mine a conversation, session transcript, or design discussion for architectural decisions before writing ADRs. Identifies problem-solution pairs, trade-off debates, technology choices, and explicit "[ADR]" tags. Triggers on "what decisions did we make", "extract decisions from this chat", "find the choices in our discussion", or "summarize architectural decisions". Also useful after long planning sessions to capture decisions that were made implicitly. Does NOT write ADR documents — use adr-writing or write-adr for that.

Use when writing or formatting an ADR document using the MADR template, applying Definition of Done (E.C.A.D.R.) criteria, or verifying ADR completeness. Triggers on "write the ADR", "format as MADR", "check ADR quality", "mark gaps in ADR". Also triggers when a decision has been extracted and needs to become a document. Does NOT extract decisions from conversations (use adr-decision-extraction) or orchestrate the full extract-confirm-write workflow (use write-adr).

Use when auditing an agent codebase against the 12-Factor Agents methodology, reviewing LLM-powered system architecture, or assessing agentic app compliance. Triggers on "analyze agent architecture", "12-factor audit", "how compliant is this agent", or "evaluate this LLM app". Also applies when comparing frameworks or planning agent improvements. Not for quick checklists — this performs deep per-factor codebase analysis with file-level evidence.

Use when the user wants a cited, structured read of local documents and project knowledge. Triggers on: "analyze these docs", "scan my project for context", "read the docs folder", "summarize what's in .beagle/concepts/", "extract context from docs/", "what's in this folder", "go read everything in X and tell me what's there". Also invoked programmatically by other beagle skills (prfaq-beagle Ignition, brainstorm-beagle reference points, strategy-interview context grounding) via the companion contract. Does NOT trigger on codebase lookups ("find this function", "search the repo"), web research (use web-research), LLM-as-judge evaluation (use llm-judge), or document editing (use humanize-beagle). Produces a written scan plan, parallel-subagent findings, and a cited synthesis report on disk — never inline prose, never unsourced claims.
