How to use @JniType annotations for ergonomic JNI. Relevant for Java files that use @NativeMethods or @CalledByNative.

Workflow for converting unit tests to browser tests for Project Bedrock. Invoke this when the user wants to remove complex Browser dependencies from tests.

List recent git commits linked to agent sessions, optionally filtered by branch or repo. Use when the user asks "show agent commits", "what has the agent shipped", "list linked commits", or wants commits with their session context.

Review recent code changes for reuse, code quality, and efficiency, then directly apply straightforward cleanup improvements. Use when the user wants a post-implementation cleanup pass, pre-PR polish, or asks to simplify/refine recent changes. Invoke with `/simplify` or `/simplify <focus>`.

Review changed code for correctness, security, code quality, and performance. Use when the user asks to review code changes, a PR, or specific files. Invoke with `/review`, `/review <pr-number>`, `/review <file-path>`, `/review <pr-number> --comment` to post inline comments on the PR, `/review --fix` to apply the findings to your working tree, or `/review <pr-number> --resume` to continue an interrupted review of that PR instead of starting over. Add `--effort low|medium|high` to trade depth for speed (defaults to high for PRs, medium for local changes). Add `--topology minimal` to run the single-pass A/B comparison arm instead of the pipeline.

Workflow for creating new applications from scratch. Covers requirements gathering, tech stack selection, scaffolding, implementation, and delivery of a functional prototype.

U.S. SEC EDGAR fetch interface — resolve a ticker to its CIK, list recent filings (10-K / 10-Q / 8-K and friends) with primary-document URLs, and pull XBRL companyfacts financial series. Free, no API key; rate-limited by IP so every request is throttled and carries a contact User-Agent. United States only.

Perpetual futures funding rate analysis and cash-carry basis trading — funding rate regimes, annualized basis signals, carry trade construction, and funding rate arbitrage between exchanges.

Dividend stock analysis for income, dividend-growth, and shareholder-return strategies, including yield quality, payout sustainability, ex-dividend mechanics, and yield-trap checks.

The single ROUTER for every data need. Load this skill BEFORE any backtest, data-fetch, or research task to pick the best available source/tool, honour auth (env) requirements, and avoid ban-risk providers.

Summarize or extract text/transcripts from URLs, podcasts, and local files (great fallback for “transcribe this YouTube/video”).

Pack and analyze codebases into AI-friendly single files using Repomix. Use when the user wants to explore repositories, analyze code structure, find patterns, check token counts, or prepare codebase context for AI analysis. Supports both local directories and remote GitHub repositories.

Group rows with columnGroupingFeature, groupedRowModel, groupedColumnMode, and manualGrouping. Load for grouped or placeholder cells and grouping interactions with expansion or pagination.

Apply globalFilter across eligible columns with globalFilteringFeature, columnFilteringFeature, filteredRowModel, globalFilterFn, and manual server filtering. Load when columns unexpectedly participate or a global filter changes state without changing rows.

Expand hierarchical subrows or custom detail panels with rowExpandingFeature, expandedRowModel, getSubRows, getRowCanExpand, manualExpanding, and paginateExpandedRows. Load when expansion state changes but no UI appears.

Create a reusable Lit useAppTable/createAppColumnHelper layer with host-backed controllers, shared features/defaults, typed cell/header renderers, App wrappers, and useTableContext for custom-element controls. Load when multiple Lit tables share infrastructure or prop drilling obscures table context.

Read, track, initialize, control, and reset TanStack Ember Table v9 state through Glimmer-reactive table APIs, baseAtoms, atoms, store, Ember createAtom, or @tracked state plus on*Change. Load for ownership precedence, updater callbacks, stale template state, options-thunk reactivity, or incorrect table.Subscribe/store.subscribe usage.

Drive a PR to a clean review (Greptile 5/5, zero open threads) — ships if needed, keeps it mergeable against staging, re-triggers both Greptile and cubic, fixes real findings, replies to and resolves every thread, and loops until clean

Add a new LLM model to apps/sim/providers/models.ts with specs verified against the provider's live API docs (no hallucination)

Create or update a Sim integration block with correct subBlocks, conditions, dependsOn, modes, canonicalParamId usage, outputs, and tool wiring. Use when working on `apps/sim/blocks/blocks/{service}.ts` or aligning a block with its tools.
