Interactive tutorial where the agent teaches Medusa development by guiding you through building a brands feature, with lessons and verification checkpoints.

  • Works in 12 steps: Greet and Orient → Check Prerequisites → Present Lesson Overview → …
  • Learning Medusa development from scratch with a guided build
  • SKILL.md covers Overview, Tutoring Protocol, Three-Lesson Structure and Checkpoint Verification Pattern, plus 3 more sections
  • Calls git

What it does

This is a tutoring session rather than a reference. The agent plays a patient coding bootcamp instructor while you build a brands feature that creates brands through the API, links them to products and shows them in the admin dashboard. Along the way it teaches the module, workflow and API route pattern, module links between modules, workflow hooks that extend core flows and admin UI customization.

The protocol is greet and orient, check prerequisites such as an initialized Medusa project and a ready environment, preview each lesson, then guide in small steps: explain, implement together, verify. After each major piece it asks verification questions, reviews your code, tests with you and debugs errors using a troubleshooting guide, moving on only when a step works. The folder holds architecture notes, checkpoint files, three lessons and a common-errors guide.

When your agent uses it

  • Learning Medusa development from scratch with a guided build
  • Understanding how modules, workflows and API routes fit together in Medusa
  • Practicing Medusa admin dashboard customization with checkpoints

Example prompts

  • “Teach me how to build with Medusa.”
  • “Guide me through creating a brands module and linking it to products.”
  • “I want to learn Medusa, so start the tutorial and check my setup first.”

Requirements

  • A Medusa project, or willingness to initialize one
  • Node.js and a database for local development

Workflow steps

12 steps, taken from the step headings in SKILL.md.

  1. Greet and Orient
  2. Check Prerequisites
  3. Present Lesson Overview
  4. Guide Step-by-Step
  5. Verify at Checkpoints
  6. Teach Architecture
  7. Handle Errors as Teaching Opportunities
  8. Answer Questions with MCP
  9. Ask Verification Questions
  10. Review Code
  11. Test Together
  12. Diagnose Errors

What it can do on your machine

Read from SKILL.md and the folder at commit 066132d. 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

    Shell commands in SKILL.md call:

    • git

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.

    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

Learning Medusa loads about 4.1k tokens when it runs. Until then it costs about 78 tokens; SKILL.md has 1,500 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~78
When it runs · the whole SKILL.md, loaded when a task matches
~4.1k

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.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 1,500 words (~4,135 tokens).

“This is NOT a passive reference skill. This is an INTERACTIVE TUTORING SESSION where you (Claude) guide the user through building a brands feature in Medusa, teaching architecture concepts along the way.”
