Agent guidance for working with Preset, Apache Superset, and Superset MCP tools. The skills work across Claude, OpenAI Codex, Cursor, GitHub Copilot, Snowflake Cortex Code CLI, and Gemini CLI from a single source.

The installable packages are:

• preset-api-skills — focused skills for direct Preset Management API, Superset workspace API, and Snowflake Cortex API workflows.
• preset-mcp-skills — focused skills for Superset MCP tool workflows.
• preset-cli-skills — focused skills for Preset CLI (sup) shell, scripting, CI/CD, read/export, SQL, and gated mutation workflows.

API package highlights:

• preset-api — authenticate with the Preset Management API (JWT exchange, base URLs, pagination, safety policy). Required by the other skills.
• preset-workspaces — list teams and workspaces, resolve workspace hostnames, inspect membership and status.
• preset-admin — manage team memberships, workspace lifecycle, invites, roles, and audit logs with confirmation-gated mutations.
• preset-dashboards — inspect dashboards, charts, datasets, and chart data with safety boundaries.
• preset-sql-execution — run or route SQL Lab execution, result retrieval, exports, and saved-query mutations with explicit approval.

See the API package README for the full catalog (17 skills covering datasets, SQL Lab, embedding, guest tokens, RLS, database connections, role/permission changes, destructive imports, and Snowflake Cortex Agents).

MCP package highlights:

• preset-mcp — route MCP intent and enforce the no-direct-API boundary.
• preset-mcp-discovery — use MCP health, list, detail, schema, and chart-type discovery tools.
• preset-mcp-visualization — create Explore links, chart previews, saved charts, and chart updates through MCP.
• preset-mcp-sqllab — run SQL, open SQL Lab links, and save SQL queries through MCP.
• preset-mcp-troubleshooting — handle MCP health, validation, permission, response-size, and bug-report workflows.

See the MCP package README for the full 8-skill catalog.

CLI package highlights:

• preset-cli — install and authenticate sup, select workspaces, choose output formats, run read-only asset workflows, and handle SQL/data-returning reads with safety boundaries.
• preset-cli-mutations — handle sup push, --force, --overwrite, user push/invite, and cross-workspace sync with mandatory preview and confirmation.

See the CLI package README for the full 2-skill catalog.

Install or load each package from its plugin directory, not from the repository root. Use preset-api-skills for direct API workflows. Use preset-mcp-skills for MCP workflows. Use preset-cli-skills for explicit sup CLI workflows. Do not use API or CLI skills as a fallback for MCP-only work, and do not use MCP or CLI skills for direct API work.

Find your client in the table above, then follow its section below. The GitHub repository is preset-io/agent-skills; preset-agent-skills is the marketplace name used by plugin install commands.

Claude Desktop installs these as individual Skill ZIP uploads.

1. Open Claude Desktop → Settings → Connectors, then click the Customize link.
2. In Customize, select Skills in the sidebar, click the + next to "Skills", then choose Create skill → Upload a skill.
3. Download the per-skill ZIPs from the latest GitHub Release.
4. Upload each skill ZIP one by one. Start with only the skills relevant to your work, such as preset-api.zip for direct API workflows, preset-mcp.zip / preset-mcp-discovery.zip for MCP workflows, or preset-cli.zip / preset-cli-mutations.zip for sup CLI workflows.
5. Restart Claude Desktop after uploading or replacing skill ZIPs.

From any Claude Code session:

/plugin marketplace add preset-io/agent-skills
/plugin install preset-api-skills@preset-agent-skills
/plugin install preset-mcp-skills@preset-agent-skills
/plugin install preset-cli-skills@preset-agent-skills

Updates ship when we publish a new version — the version is bumped in the plugin manifests and tagged. Run /plugin update (or re-run /plugin install) to pull it.

Claude.ai web does not run plugins, so each skill must be uploaded individually as a Skill ZIP.

Easiest path: install Claude Desktop (free, same account) and follow the individual Skill ZIP upload steps above.

Web-only path: download the per-skill ZIPs from the latest GitHub Release, then in claude.ai open Settings → Capabilities → Skills, click Upload Skill, and upload each ZIP. You only need the skills relevant to your work.

To build the same ZIPs locally instead of downloading a release, run:

node scripts/build-claude-web-skills.mjs
node scripts/build-claude-web-skills.mjs \
  --source plugins/preset-mcp-skills/skills \
  --out dist/claude-web-flat-mcp-skills
node scripts/build-claude-web-skills.mjs \
  --source plugins/preset-cli-skills/skills \
  --out dist/claude-web-flat-cli-skills

Install the plugin from GitHub:

codex plugin marketplace add preset-io/agent-skills --ref master
codex plugin add preset-api-skills@preset-agent-skills
codex plugin add preset-mcp-skills@preset-agent-skills
codex plugin add preset-cli-skills@preset-agent-skills

Use a release tag (e.g. --ref v0.4.0) instead of master for a pinned install. Restart Codex after installing so the new skills are loaded into the next session.

Cursor imports this repository as a GitHub-backed project rule. Use the .git clone URL; Cursor rejects the plain repository URL in the import dialog.

1. Open Cursor Settings → Rules.
2. In Project Rules, click Add Rule.
3. Select Remote Rule (Github).
4. Enter the HTTPS clone URL:

   https://github.com/preset-io/agent-skills.git
   

Copilot only auto-loads instructions from a repository-root .github/copilot-instructions.md. Copy the package instructions you need into the .github/ directory of the consuming repository, or reference their content from your own .github/copilot-instructions.md: plugins/preset-api-skills/.github/copilot-instructions.md for direct API workflows, plugins/preset-mcp-skills/.github/copilot-instructions.md for Superset MCP workflows, and plugins/preset-cli-skills/.github/copilot-instructions.md for sup CLI workflows. Copilot loads the file whenever it edits code in that repo.

Cortex Code CLI supports custom skills from local folders and Git repositories. Install the public repo, then confirm the skills are visible:

/skill add https://github.com/preset-io/agent-skills.git
/skill list

If remote discovery does not pick up the nested package folders, clone the repo and add the package skill directories directly:

git clone https://github.com/preset-io/agent-skills.git
cortex skill add agent-skills/plugins/preset-api-skills/skills
cortex skill add agent-skills/plugins/preset-mcp-skills/skills
cortex skill add agent-skills/plugins/preset-cli-skills/skills

Use the API package for direct Preset/Superset API and Snowflake Cortex Agent workflows, the MCP package for Superset MCP workflows, and the CLI package for sup workflows.

Gemini CLI uses GEMINI.md context files rather than installable skill packages. Clone the public repo, then import the package instructions from your global or project GEMINI.md:

git clone https://github.com/preset-io/agent-skills.git

@/path/to/agent-skills/plugins/preset-api-skills/AGENTS.md
@/path/to/agent-skills/plugins/preset-mcp-skills/AGENTS.md
@/path/to/agent-skills/plugins/preset-cli-skills/AGENTS.md

Run /memory refresh in Gemini CLI after updating GEMINI.md.

• Claude Desktop and Claude.ai web: download the latest release ZIPs and upload or replace the skills again.
• Claude Code and OpenAI Codex: re-run the install commands, or pin to a newer release tag when you want deterministic installs.
• Snowflake Cortex Code CLI: re-run /skill add for the Git URL, or pull the local clone and re-run cortex skill add.
• Gemini CLI: pull the latest repo contents, then run /memory refresh.

Ask your AI tool something the installed skills are designed for, for example:

"Using the Preset API, list the workspaces I have access to." "Using Superset MCP tools, list dashboards." "Using the Preset CLI, show me the sup command to export dashboards as JSON."

The tool should reference one of the Preset skills or package instruction files (such as preset-workspaces, preset-api, preset-mcp-discovery, or preset-cli). If it doesn't, the plugin, skill, or context instructions are not loaded — re-check the install steps for your client.

This repository keeps client metadata next to each package for contributors and debugging:

• Claude marketplace metadata: .claude-plugin/marketplace.json and each package's .claude-plugin/plugin.json.
• Codex marketplace metadata: .agents/plugins/marketplace.json and each package's .codex-plugin/plugin.json.
• Cursor package metadata: each package's .cursor-plugin/plugin.json.
• Copilot instructions: each package's .github/copilot-instructions.md.
• Claude Desktop/web ZIP generation: scripts/build-claude-web-skills.mjs.

Run the repository smoke test before publishing changes:

./scripts/smoke-test.sh

It includes node scripts/validate-agent-skills.mjs, which checks the source skill folders against the Agent Skills structural rules: required frontmatter, name and description limits, parent-directory name matching, compact SKILL.md files, and local Markdown links that stay inside each skill folder.

The package version is single-sourced in the top-level VERSION file and stamped into every provider manifest (the .claude-plugin, .codex-plugin, and .cursor-plugin plugin.json for each package). Claude Code and OpenAI Codex cache plugins by this version and only surface an update when it changes, so the manifests must stay in lockstep with the published git tag — other clients track the repo or release tag directly.

To cut a release:

1. Bump VERSION (semver MAJOR.MINOR.PATCH).
2. Run node scripts/sync-version.mjs to stamp it into every manifest.
3. Commit and merge the PR to master.

After the merge, the Auto version tag workflow creates vX.Y.Z when that tag is missing, then dispatches the private release build and the public mirror/release workflow. The tag must equal VERSION.

node scripts/sync-version.mjs --check runs in the smoke test and CI and fails if any manifest drifts from VERSION; the release workflow additionally fails if the tag does not match VERSION.
