Install

Start with the ZIP package, then choose the AI tool workflow that fits your setup.

Download env-doctor.zip (992 B).
Open the package and read SKILL.md, plus any included references, templates, or scripts.
Use the instructions directly in any AI tool that supports reusable instructions, project knowledge, custom agents, or uploaded reference files.

For Claude Code, unzip into ~/.claude/skills/ so the folder lands at ~/.claude/skills/env-doctor/, then reload Claude Code. For Claude.ai, upload the same ZIP from Customize → Skills.

Use with other AI tools

This package is not locked to one vendor. If your AI tool does not support Claude-style skills, copy the core instructions from SKILL.md into the tool's custom instructions, project prompt, agent setup, or reusable prompt library.

Upload or paste any included reference files as project knowledge where your tool supports it.
Keep the output format from SKILL.md intact so results stay predictable.
Run a small test with your own data before using the workflow in production.

Compatibility depends on the features your AI tool provides. Treat scripts as optional local helpers unless your environment can run them safely.

Claude installation reference

The ZIP also follows Claude's Agent Skills structure: a folder with a required SKILL.md file plus optional scripts, references, templates, and resources.

What it does

Env Doctor checks a project's required environment variables before a deploy. It is built for agent-run workflows where one duplicated or missing value can break a Sanity publish or Netlify build.

When to use it

Before publishing generated content to Sanity
Before triggering a Netlify build hook
After changing .env, .env.local, or CI secrets

What it reports

The skill returns a compact report with missing keys, suspicious duplicated values, malformed URLs, and suggested next steps.

Check this repo's Sanity and Netlify environment before deploy.

Limitations

It does not print secret values. It only reports key names, validation status, and safe hints.

Verdict 4/5

Useful for projects where one wrong env value can break publishing, especially before Sanity or Netlify deploys.
