Write a postmortem for a regression that escaped to production, broke real users, and traces back to a design flaw worth documenting for future implementors. Only invoke after confirming no existing postmortem or doc covers the same root cause.

Use when a code/test/comment diff is called bloated, slop, LLM slop, bullshit, WTF, crap, rubbish, embarrassing, overengineered, adhoc, or "not paid by LOC"; or when symptoms include bloated comments, superfluous planning .md / .tools / one-time setup / phase-or-sprint tags, huge-file growth instead of new-file extraction, 5 copy-pasted tests that should be 1 parametrized test, duplicated test setup, reinvented helpers, near-duplicate logic across files, low reuse, 4+ new module-level helpers for one bugfix, fresh whole-AST/IR/syntax-tree walkers, or 150+ added LOC for one bugfix. Also use proactively before opening a PR whose diff smells like any of the above.

Implementation details for the EF Core dotnet-ef CLI and tooling. Use when changing dotnet-ef commands, the ef wrapper, EFCore.Tools (PMC), or EFCore.Tasks MSBuild integration.

Implementation details for EF Core LINQ query translation, SQL generation, and bulk operations (ExecuteUpdate/ExecuteDelete). Use when changing expression visitors, SqlExpressions, QuerySqlGenerator, ShaperProcessingExpressionVisitor, UpdateExpression, DeleteExpression, or related classes.

Create new Agent Skills for GitHub Copilot. Use when asked to create, scaffold, or add a skill. Generates SKILL.md with frontmatter, directory structure, and optional resources.

Create custom GitHub Copilot agents. Use when asked to create, scaffold, or configure a custom agent, declarative agent, or @-invokable chat participant for GitHub Copilot.

Implementation details for EF Core change tracking. Use when changing InternalEntityEntry, ChangeDetector, SnapshotFactoryFactory, or related entity state, snapshot, or property accessor code.

Detect and use Crabbox for repository tests and validation on remote runners. Use when crabbox.yaml or .crabbox.yaml exists, the crabbox CLI is available, or work needs remote compute, a clean or reusable environment, target-platform coverage, or auditable execution evidence.

Use when generating short videos with RedBox official video API. Produces a detailed shot script first, asks the user to confirm it, then chooses between text-to-video, reference-guided, and first-last-frame modes and calls the correct wan2.7 video model with prompt discipline focused on motion, reference elements, and transitions.

Agent Loop for cross-device sync/transfer issues: collect environment fingerprints from BOTH machines first, check memory for known patterns, manage hypotheses with forced falsification, and persist evidence via $wrap. Orchestrates dual-side-debug + local-log-debug + systematic-debugging into a structured loop.

Resume work from a $wrap state file. Reads the structured active-task.json, presents a context summary, restores branch state, and lets you pick up exactly where the last session left off — no manual context rebuild.

Import code from GitHub gists/files/repos, GitLab, URLs, DOM, and local files. Export projects as HTML, JSON, ZIP, or to external services. Load this skill when loading projects from external sources or exporting project state.

Use when changing ghost board generation, path / road / river continuity, deterministic regen, edge connections, or anything that runs inside makeGhostWorld in tiny-world-builder.html.

Monitor a list of tickers for key changes in price, IV rank, unusual activity, earnings dates, and score changes. Supports custom watchlists and a default "hot options" list. Triggers: "add AAPL to watchlist", "my watchlist", "watch NVDA TSLA META", "watchlist alerts", "remove SPY from watchlist", "hot options", "what's on my watchlist", "watchlist summary", "daily watchlist"

Recommends optimal multi-leg option strategies based on your market view (bullish, bearish, neutral, volatile). Supports 15+ strategy templates including spreads, condors, straddles, and income plays. Returns full P&L profile, breakevens, and probability of profit. Use when: choosing an options strategy, planning a trade around earnings, building a multi-leg position, comparing strategy alternatives.

Set price, IV, or activity-based alerts with contextual notifications. Alert types include IV rank threshold crossing, price support/resistance breaks, unusual activity detection, earnings approaching, and VRP signal changes. Triggers: "alert me when AAPL IV rank above 80", "notify if NVDA drops below 850", "earnings alert for TSLA", "VRP alert", "set price alert", "alert when IV spikes", "notify on unusual activity", "my alerts", "delete alert"

AI DevKit · Design phase guidance for reviewing feature design against requirements. Use when the user wants to validate architecture, review design docs, resolve design trade-offs, or run dev-lifecycle phase 3.
