Cut a Malloy Publisher release, and write the RELEASENOTES.md entries a release ships. Use when asked to release, cut a release, ship a version, or publish Publisher to npm/Docker — and when a change needs a release note, or you are deciding whether it does and what version to stamp on it.

Common data analysis pitfalls to watch for during query construction and result interpretation. Reference this checklist when verifying queries and results to catch errors before presenting an answer.
Skill Claude CodeCodex
Combine validated Malloy queries into a notebook report or dashboard. Use when the user asks to "create a report", "build a dashboard", "combine these into a report", or wants a persistent multi-query artifact.
Skill Claude CodeCodex
Workflow for answering data questions against Malloy semantic models over MCP - structured discovery with getcontext, query construction with executequery, verification, and answer delivery. Use whenever the user asks a data question, wants a metric, a breakdown, a trend, or a chart over a model.
Skill Claude CodeCodex
Open-ended exploration with no specific question to answer, and building views/dashboards/notebooks on an existing model. Use when the user asks "what's interesting?", "explore this data", "find insights", "look for patterns", "build a dashboard", or "create views". Not for a specific data question - answering one is…
Skill Claude CodeCodex
Chart selection guidance and renderer reference for Malloy views. Use when choosing visualization types, adding chart annotations, user asks "what chart should I use", "how should I visualize this", or when deciding between barchart, linechart, scatterchart, etc.
Skill Claude CodeCodex
Build or modify a Malloy Publisher dashboard, a tagged .malloy file in a package's dashboards/ directory, with auto-rendered filter controls, a grid layout, and # drill click-through. Use when the user asks for a dashboard, a filterable operational view, or drill-through between views, and no code is wanted.
Skill Claude CodeCodex
Fix Malloy compile errors and understand error messages. Use when encountering errors in .malloy files, user says "fix this error", "malloy error", "compile error", "syntax error", or sees 20+ cascading errors.
Skill Claude CodeCodex
Propose a source plan and field definitions for a Malloy semantic model. Covers picking which sources to model and at what grain, then proposing the specific renames, dimensions, and measures per source, every proposal backed by querying the data.
Skill Claude CodeCodex
Silent data discovery for Malloy modeling. Used at Step 1 of the modeling workflow. Scans tables, columns, distributions, and relationships without user interaction. The agent builds an internal picture before presenting anything.
Skill Claude CodeCodex
Add documentation with #(doc) tags to Malloy models so fields and sources are described in plain language. Use when user asks to "add documentation", "add doc tags", "document the model", or wants fields and sources described for natural-language search and discovery. For declaring parameterizable filters with…
Skill Claude CodeCodex
First steps for using a Malloy Publisher deployment through its MCP tools. Use when connecting to Publisher for the first time, when you do not yet know the available environments, packages, or models, or when a user asks what data they can explore. Covers verifying the server, discovering data with malloygetContext…

Common Malloy modeling mistakes and how to avoid them. Read BEFORE writing source definitions, dimensions, measures, or joins. Covers reserved words, NULL checks, date functions, type casts, field management (extend except/accept/rename vs include public/internal/private), and query-based source gotchas.
Skill Claude CodeCodex
Common Malloy query and view mistakes. Read BEFORE writing views, queries, or notebooks. Covers chart constraints, aggregate filters, joined field aliasing, method syntax, and time truncation vs extraction.
Skill Claude CodeCodex
Common Malloy renderer annotation mistakes. Read BEFORE adding chart annotations, formatting tags, or building dashboards. Covers tag syntax, scale rules, sparkline setup, and bigvalue patterns.
Skill Claude CodeCodex
Embed an in-package HTML data app into a host page or another application, including auto-sizing and auth. Read when embedding a Publisher page via Publisher.embed.
Skill Claude CodeCodex
Write the JavaScript that drives an in-package HTML data app, calling Publisher.query, building queries from filter state, and handling results and errors. Read before writing the page's data code.
Skill Claude CodeCodex
Build or modify an in-package HTML data app for a Malloy Publisher package (a public/ directory the package serves). Use when the user wants a hand-authored HTML dashboard or web page backed by a package's Malloy models, with no build step.
Skill Claude CodeCodex
Analyze LookML files as prior art for Malloy modeling. Used during Step 1 (DISCOVER) when .lkml files are present. Coordinates reference files that extract business logic, relationships, and curation decisions. Works with or without a database connection.
Skill Claude CodeCodex
Optimize a package's Malloy Persistence materializations for cost and performance using the malloy-pub CLI and the materialization history. Recommend what to persist, what to stop persisting, and how to schedule/scope it. Use when the user asks to make a package cheaper or faster, tune persistence, decide what to…
Skill Claude CodeCodex
Add and debug Malloy Persistence materializations in a package - persist an expensive source so queries read a pre-built table. Read this whenever the user wants to materialize a source, add a persist annotation, speed up a slow source, or asks why a persist source isn't building.
