What it does
Dagster Expert is an agent skill from dagster-io/skills, published by the product's own GitHub organization. Use for any task involving Dagster, the dg CLI, assets, materialization, components, data tools or data pipelines, matching the situations the Dagster skill handles. This is the deprecated dagster-expert plugin. It carries no Dagster guidance and exists only to tell the user to move to the dagster plugin.
Its SKILL.md is about 320 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Data & Analytics, covering Data pipelines and ETL. It works with Dagster. The repository describes itself as: A collection of AI skills for working with Dagster. The licence is Apache-2.0.

Example prompts
- “/dagster-expert”
What it can do on your machine
Read from SKILL.md and the folder at commit 8547cac. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Dagster Expert loads about 321 tokens when it runs. Until then it costs about 80 tokens; SKILL.md has 130 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- description
- Use for any task involving Dagster, the dg CLI, assets, materialization, components, data tools or data pipelines, matching the situations the Dagster skill handles. This is the deprecated dagster-expert plugin. It carries no Dagster guidance and exists only to tell the user to move to the dagster plugin.
This plugin has been replaced
The user is running the deprecated dagster-expert plugin. It no longer carries the Dagster skill — that now ships in the dagster plugin.
Do not answer the user's Dagster question from memory. Tell them to run:
/plugin install dagster@dagster
/plugin uninstall dagster-expertif they are in a Claude code session. If they are in a Cursor session, instruct them to uninstall the current Dagster plugin and re-install it.
Both commands matter. Installing dagster without uninstalling dagster-expert leaves two plugins providing a skill named dagster-expert, and this deprecated one may be chosen instead of the real one. If the user reaches this notice after already installing dagster, that is what has happened — have them uninstall dagster-expert and retry.
Nothing else changes: the skill keeps the name dagster-expert and is still invoked as /dagster-expert.
