Envcheck

Check if your environment is ready to run a skill — verify that required environment variables are set and required CLI binaries are on PATH. Returns a ready/not-ready verdict with lists of present and missing items.

Pre-flight check: does this environment have what the skill needs?

Start the server

bash

uvicorn envcheck.app:app --port 8007

Check environment

bash

curl -s -X POST http://localhost:8007/v1/check-env \
  -H "Content-Type: application/json" \
  -d '{"required_env": ["HOME", "PATH"], "required_bins": ["python", "git"]}' | jq

Returns ready (true/false), present_env, missing_env, present_bins, missing_bins.

Pair with ScopeCheck

Use ScopeCheck to find out what a skill needs, then EnvCheck to verify your environment has it:

bash

# Step 1: What does the skill need?
SCOPE=$(curl -s -X POST http://localhost:8002/v1/check-scope \
  -H "Content-Type: application/json" \
  -d "{\"skill_content\": $(cat SKILL.md | jq -Rs)}")

# Step 2: Do we have it?
curl -s -X POST http://localhost:8007/v1/check-env \
  -H "Content-Type: application/json" \
  -d "{\"required_env\": $(echo $SCOPE | jq '.detected.env_vars'), \"required_bins\": $(echo $SCOPE | jq '.detected.cli_tools')}" | jq '.ready'
