Reference for the fused CLI — environment management, file storage, secrets, code execution, and infrastructure commands. Use when writing or explaining shell commands that invoke fused, or when helping users set up, switch between, or provision environments. If the commands are part of building or running a project…

Best practices for running code through fused's executecode tool. Use when writing or reviewing any mcpopenfusedexecutecode call — covers how to structure user code, choose a data library, handle results, and write outputs to the file store. For security scanning, spec checks, and testing see fused-verify. If this is…

Show the human a real browser UI — to ask a question, get an approval/decision, or review a plan — built from Fused's JSON-UI primitives and opened with fused widget open (one-shot — inline --config or a .json file) or the parley (widget push/widget watch, standing). Use in Claude Code whenever a structured choice…
Skill Claude CodeCodex
Entry-point router for the Fused skills in this repo. Use when a user asks how to get started with, set up, or install Fused, how to build a project or UDF, how to get a widget UI / dashboard out of Fused, or is unsure which Fused skill to load. Maps a goal to the specific skill(s) to read next.

Authoring standalone HTML artifacts — scripts/ /main.html documents that Fused and Flow serve full-bleed and wire to a window.fused runtime (callUdf / runSql / params). Use when the output of a project is a bespoke interactive HTML page — a custom chart, a form, a report, a small app — that calls UDFs and runs SQL…
Skill Claude CodeCodex
Reference for the infrastructure managed by fused — what resources exist, why each one is needed, and when they are created, updated, or deleted. Covers the AWS backend (IAM, Lambda, ECR, S3) and the local backend (data directories + venvs, see "Local backend infra"). Use when helping users understand, provision, or…
Skill Claude CodeCodex
The canonical end-to-end guide for an agent driving Fused — pick an environment, create a project, decompose a task into UDFs, author specs and code, validate + commit, run/preview locally (often as a rendered widget), and deploy through preview to release. Code is authored by the driving agent (no codegen command, no…
Skill Claude CodeCodex
Step-by-step guide for installing and setting up fused for the first time, including AWS credential checks, detecting an existing installation, provisioning infrastructure, and verifying the setup. Use when a user asks how to install, configure, or get started with openfused.

The fused storage and secrets MCP tools — inspecting cloud-native datasets and managing secrets. Use when finding/listing/counting S3 objects, reading a Parquet/Arrow/CSV schema, minting a download URL, uploading content, or storing/reading/deleting secrets, via…
Skill Claude CodeCodex
Security scanning, testing, and correctness validation for code running in openfused. Use when writing or reviewing verifycode, testcode, getauditlog calls, or when advising on security policy, spec checks, data expectations, or code quality in the fused context. If you're validating code that belongs to a project…

Authoring and previewing JSON-UI widgets as the response of running a project — the py-UDF-computes → json-widget-visualizes pattern, the {{ref}}/$param data grammar, how resolution runs through the compute backend, and the CLI surfaces (widget open, parley, deployed URL) that put a rendered widget in front of a…
Skill Claude CodeCodex
Use when a Fused canvas.toml contains (or needs) a [[comments]] block — e.g. the user asks to check/fix/resolve canvas comments, review feedback pins on a canvas, or leave comments on a canvas for someone else. Covers reading, writing, and resolving comments via the fused CLI pull/push workflow.
Skill Claude CodeCodex
Format reference for canvas.toml files that define a Fused canvas (nodes, edges, viewport) plus the surrounding folder layout ({udfName}.py, .json, .md, .html, shared.fused). Use when creating, editing, or validating any canvas.toml, adding/removing UDF nodes, wiring edges, defining folder groupings, or scaffolding a…
Skill Claude CodeCodex
Reference for using Fused's built-in integration connections inside UDFs. Covers data sources (Snowflake, BigQuery, GCS, S3, Airtable, Notion, Google Drive), compute/inference providers (Modal, Hugging Face, Baseten, Daytona, ComfyOrg, Slack), and LLM providers (Anthropic, OpenAI) — the fused.api connect helpers…
Skill Claude CodeCodex
Orientation to what Fused is and when to use it. Use when deciding whether to use Fused for a task, planning a new Fused project, or understanding Fused's capabilities as a remote Python execution platform.
Skill Claude CodeCodex
Comprehensive guide for writing Fused User Defined Functions (UDFs). Use when helping users create, optimize, or debug UDFs, including function structure, parameter handling, performance optimization, agent-friendly design, and security best practices.

JSON schemas for Fused canvas UI widget components (text, text-input, button, dropdown, charts, maps, sql-table, form, transformer, etc.). Use when authoring or editing widget JSON files (e.g. widget.json in canvas directories), validating widget props, or answering questions about which fields a given widget type…
