dev-verify
REQUIRED Phase 7 of /dev workflow (final). Requires fresh runtime evidence before claiming completion.
dev
Orchestrates 7-phase feature implementation workflow with user approval gates and TDD enforcement.
ds-brainstorm
REQUIRED Phase 1 of /ds workflow. Uses Socratic questioning to clarify goals, data sources, and constraints.
ds-delegate
Subagent delegation for data analysis. Dispatches fresh Task agents with output-first verification.
ds-implement
REQUIRED Phase 3 of /ds workflow. Enforces output-first verification at each step.
ds-plan
REQUIRED Phase 2 of /ds workflow. Profiles data and creates analysis task breakdown.
ds-tools
This skill should be used when the user asks "what plugins are available", "list data science tools", "what MCP servers can I use", "enable code intelligence", or needs to discover available plugins like serena, context7, or data access skills like wrds and lseg-data.
ds-verify
REQUIRED Phase 5 of /ds workflow (final). Checks reproducibility and requires user acceptance.
ds
Orchestrates 5-phase data analysis workflow with output-first verification.
exit
Deactivate the sandbox and restore full access to Bash and Write/Edit tools.
gemini-batch
This skill should be used when the user asks to "use Gemini Batch API", "process documents at scale", "submit a batch job", "upload files to Gemini", or needs large-scale LLM processing. Includes production gotchas and best practices.
jupytext
This skill should be used when the user asks to "convert notebook to text", "use jupytext", "version control notebooks", "share data between kernels", "set up multi-kernel project", "pair notebooks with Python files", "sync ipynb and py files", or needs multi-kernel projects (Python/R/Stata/SAS) with version-control-friendly notebooks.
look-at
This skill should be used when the user asks to 'look at', 'analyze', 'describe', 'extract from', or 'what's in' media files like PDFs, images, diagrams, screenshots, or charts. Triggers include: 'what does this image show', 'extract the table from this PDF', 'describe this diagram', 'what's in this screenshot', 'analyze this chart', 'read this image', 'get text from this PDF', 'summarize this document', or requests for specific data extraction from visual or document files. Use when analyzed/interpreted content is needed rather than literal file reading (which uses Read tool).
lseg-data
This skill should be used when the user asks to "access LSEG data", "query Refinitiv", "get market data from Refinitiv", "download fundamentals from LSEG", "access ESG scores", "convert RIC to ISIN", or needs the LSEG Data Library Python API.
marimo
This skill should be used when the user asks to "use marimo", "create a marimo notebook", "debug a marimo notebook", "inspect cells", "understand reactive execution", "fix marimo errors", "convert from jupyter to marimo", or works with marimo reactive Python notebooks.
notebook-debug
This skill should be used when the user asks to "debug notebook", "inspect notebook outputs", "find notebook error", "read traceback from ipynb", "why did notebook fail", or needs to understand runtime errors in executed Jupyter notebooks from any source (marimo, jupytext, papermill).
using-skills
Auto-loaded at session start via SessionStart hook. Teaches skill invocation protocol, tool selection rules (look-at for media, skills for workflows), agent delegation patterns, and enforcement mechanisms. NOT user-triggered - provides foundational skill usage discipline for all sessions.
wrds
This skill should be used when the user asks to "query WRDS", "access Compustat", "get CRSP data", "pull Form 4 insider data", "query ISS compensation", "download SEC EDGAR filings", "get ExecuComp data", "access Capital IQ", or needs WRDS PostgreSQL query patterns.
