No deviations. ### Investigation Skills (Gather Info - REPORT) Load these when you need to understand something before acting. | Skill | When to Load | |-------|--------------| | `systematic-debugging` | Bug, test failure, unexpected behavior | | `code-review` | After implementation, before commit | **Key behavior:** These skills INVESTIGATE and REPORT. They don't fix. ### Workflow Skills Load these for orchestration patterns. | Skill | When to Load | |-------|--------------| | `subagent-workflow` | Dispatching or recalling subagents | | `knowledge-sync` | After major refactors, update skills with new patterns | ## Domain Skills Load these for project-specific patterns. They provide code examples and anti-patterns. ### Foundation | Skill | When to Load | |-------|--------------| | `database-first` | ANY database work - iron law: all logic in PostgreSQL | | `codebase-conventions` | File structure, naming, constraints | ### Database | Skill | When to Load | |-------|--------------| | `postgres-vectors` | Embeddings, similarity search, pgvector operators | | `postgis-spatial` | Geographic queries, ST_* functions, regions | | `game-scoring` | Candidate scoring, confidence, softmax aggregation | | `trait-learning` | Trait extraction, learning loop, LLM prompts | ### Frontend | Skill | When to Load | |-------|--------------| | `vue-composables` | useX patterns, Pinia stores, withLoadingState | | `maplibre-camera` | Camera movements, flyTo, animations | | `maplibre-layers` | GeoJSON sources, layer styling, events | | `shadcn-vue` | UI components, forms, dialogs | ### Edge Functions | Skill | When to Load | |-------|--------------| | `edge-functions` | Deno patterns, LLM calls, embeddings | ### Testing | Skill | When to Load | |-------|--------------| | `gameplay-sql` | Test game via database tools (game_start, game_turn) | | `gameplay-browser` | Test game via browser with Chrome DevTools | ## How Skills Chain Skills reference each other with `REQUIRED SUB-SKILL:` markers. Example flow: 1. User asks for feature -> load `openspec-check` 2. No spec exists -> `openspec-check` says load `openspec-propose` 3. Proposal approved -> load `task-planning` 4. Tasks ready -> load `openspec-apply` + `testing` 5. Implementation done -> load `code-review` ## Iron Law ``` ANNOUNCE WHICH SKILL YOU'RE USING BEFORE STARTING ``` Format: "I'm using [skill] to [what you're doing]." ## Selecting Skills Ask yourself: 1. Am I planning or executing? -> Planning skills ask, execution skills follow 2. Is this a new feature or existing behavior? -> New = check specs first 3. Am I writing code? -> Always load `testing` 4. Am I investigating or fixing? -> Investigate first, then fix 5. Does this involve database/frontend/edge? -> Load domain skill When in doubt, load `openspec-check` first - it will guide you to the right path. ## Domain Skill Selection Guide | Task | Primary Skill | Also Consider | |------|--------------|---------------| | Vector similarity query | `postgres-vectors` | `game-scoring` | | Geographic filtering | `postgis-spatial` | | | Candidate ranking | `game-scoring` | `postgres-vectors` | | New trait extraction | `trait-learning` | `edge-functions` | | Map camera animation | `maplibre-camera` | | | Map markers/layers | `maplibre-layers` | | | Vue reactive state | `vue-composables` | | | Pinia store | `vue-composables` | `database-first` | | UI component | `shadcn-vue` | | | LLM integration | `edge-functions` | `trait-learning` | | Manual game testing | `gameplay-sql` | `gameplay-browser` | --- > Converted and distributed by [TomeVault](https://tomevault.io/claim/discountedcookie) — claim your Tome and manage your conversions.
