The Meridian agent skill teaches your coding agent (Claude Code, Codex or Cursor) how Meridian works, so it builds, bills and deploys your Shopify app the way the platform expects instead of guessing. It pairs with Meridian MCP: the skill says what to do and in which order, and MCP gives the agent your app’s real plans, keys, deploys and logs.

​
What the agent can do with it

For anything the skill does not cover, the agent reads these docs through Meridian MCP (docs_search, docs_get) rather than answering from memory.

​
What stays with you

The skill tells the agent to leave these to you, explain why, and wait:
  • Signing in. The agent asks you to run meridian login in your own terminal, then checks the result with meridian whoami.
  • Approving Meridian MCP on the consent screen in your browser.
  • API keys and secrets. You create MERIDIAN_API_KEY on the app’s Settings → SDK page and put it in .env or your hosting variables yourself. The agent never asks you to paste a key, password or secret into the chat.
  • Dashboard setup: connecting GitHub, adding a database, setting secrets, adding a domain, choosing a plan.
It asks you to confirm before it deploys or promotes to production, rolls a deployment back, resets a developer database, or changes an active automation. The skill adds no access of its own. The CLI uses your own sign-in, and every MCP tool runs the same permission checks as the dashboard: an agent can only deploy to production if you hold hosting.promote, for example.

​
Install it

Pick one. All three install the same skill.
From your app’s root:
The command writes the skill for each agent the project already uses (all three when it finds none) and adds Meridian MCP to that agent’s project config:It merges with config files that already exist and never overwrites another server. Commit these folders so your teammates’ agents get the skill too.Run meridian skills install again after upgrading the CLI to update the skill. Replacing a skill folder that changed asks first; --yes approves it.

​
Connect Meridian MCP

The first time the agent calls Meridian MCP, approve the connection:

​
Try it

Once the skill is installed, ask your agent for a task in your own words, for example:
  • “Add Meridian billing to this app, with a pricing page and a gate on advanced reports.”
  • “Get this app running locally on my Meridian database.”
  • “Deploy main to production and tell me if anything fails.”
The skill is the same for every app. What makes the result specific to yours is Meridian MCP, so connect it before you start.
