Haskell Build Monitoring with ghcid

Start a ghcid session to monitor the build.

Before starting: Verify which command is actually allowed in .claude/settings.local.json for ghcid and ensure you use it to avoid prompting for permission.

First, check package.yaml to identify the test components:

• tests: section → use the test name with -test suffix (e.g., dota-sage-test)

Then run ghcid with the all target (which includes all libraries and executables, including internal libraries) PLUS all test components using the Bash tool with run_in_background: true:

ghcid \
  -c 'cabal repl --enable-multi-repl all <test-name>' \
  --restart=<project>.cabal \
  --test ':!cabal test' \
  --outputfile=build.log \
  --clear
