Hard gates (before reporting findings)

Run in order; do not assert an issue until the gate for that issue passes.

  1. Scope — pass when: You have the target .swift path(s) and confirmed SwiftData surface in scope (e.g. import SwiftData, @Model, @Query, @ModelActor, VersionedSchema, or migration types). If none apply, stop or narrow scope with one sentence.
  2. Reference — pass when: For each checklist area you evaluate (models, queries, concurrency, migrations), you opened the matching references/*.md from the Quick Reference table or wrote N/A: no <area> in this review with a one-line reason.
  3. Evidence — pass when: Every finding uses the [FILE:LINE] ISSUE_TITLE header (line range allowed) from the file you read; no finding without a cite.
  4. Report — pass when: Findings list cites first (or inline) using [FILE:LINE] ISSUE_TITLE, then severity or checklist grouping—no uncited assertions.

Review Checklist

  • Models marked final (subclassing crashes)
  • @Relationship decorator on ONE side only (not both)
  • Delete rules explicitly set (not relying on default .nullify)
  • Relationships initialized to empty arrays, not default objects
  • Batch operations used for bulk inserts (append(contentsOf:))
  • @Query not loading thousands of items on main thread
  • External values in predicates captured in local variables
  • Scalar comparisons in predicates (not object references)
  • @ModelActor used for background operations
  • PersistentIdentifier/DTOs used to pass data between actors
  • VersionedSchema defined for each shipped version
  • MigrationPlan passed to ModelContainer

When to Load References

  • Reviewing @Model or relationships -> model-design.md
  • Reviewing @Query or #Predicate -> queries.md
  • Reviewing @ModelActor or background work -> concurrency.md
  • Reviewing schema changes or migrations -> migrations.md

Review Questions

  1. Could this relationship assignment cause NULL foreign keys?
  2. Is @Relationship on both sides creating circular references?
  3. Could this @Query block the main thread with large datasets?
  4. Are model objects being passed between actors unsafely?
  5. Would schema changes require a migration plan?

概要と使いどころ

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.

Vercel AI Elements for workflow UI components. Use when building chat interfaces, displaying tool execution, showing reasoning/thinking, or creating job queues. Triggers on ai-elements, Queue, Confirmation, Tool, Reasoning, Shimmer, Loader, Message, Conversation, PromptInput.

Reviews App Intents code for intent structure, entities, shortcuts, and parameters. Use when reviewing code with import AppIntents, @AppIntent, AppEntity, AppShortcutsProvider, or @Parameter.

existential-birds/beagle822026年9月16日 更新

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.
