UI Checkstyle / ESLint + Prettier + organize-imports (Codex agent)

The UI Checkstyle workflow (.github/workflows/ui-checkstyle.yml) has three per-area jobs — lint-src, lint-playwright, lint-core-components. Each reformats the files changed in the PR and fails if the reformat produces a diff, so the committed tree must already be formatted.

When to activate

• The user asks to "fix UI checkstyle", "fix UI lint", "run prettier", "run eslint", "fix UI format", or similar.
• CI posts a UI Checkstyle / lint-src|lint-playwright|lint-core-components failure (the bot surfaces the modified files in the job summary).
• After you have finished authoring or editing any .ts/.tsx/.js/ .jsx/.json under the three UI trees — before opening a PR or pushing a commit that touches UI.

Procedure

1. Build the file list for each affected area:

   # repo root
   git diff --name-only origin/main...HEAD -- \
     'openmetadata-ui/src/main/resources/ui/src/**/*.{ts,tsx,js,jsx,json}' \
     | sed 's|openmetadata-ui/src/main/resources/ui/||' > /tmp/src_files.txt
   
   git diff --name-only origin/main...HEAD -- \
     'openmetadata-ui/src/main/resources/ui/playwright/**/*.{ts,tsx,js,jsx}' \
     | sed 's|openmetadata-ui/src/main/resources/ui/||' > /tmp/pw_files.txt
   
   git diff --name-only origin/main...HEAD -- \
     'openmetadata-ui-core-components/**/*.{ts,tsx,js,jsx,json}' \
     | sed 's|openmetadata-ui-core-components/src/main/resources/ui/||' \
     > /tmp/core_files.txt
   

   Skip any empty list — CI won't run that area's job either.

2. From the matching working directory (openmetadata-ui/src/main/resources/ui or openmetadata-ui-core-components/src/main/resources/ui), run the three-step sequence that CI runs:

   # 1) imports first
   cat /tmp/src_files.txt | xargs ./node_modules/.bin/organize-imports-cli
   
   # 2) ESLint --fix
   NODE_OPTIONS='--max-old-space-size=8192' cat /tmp/src_files.txt \
     | xargs ./node_modules/.bin/eslint --no-error-on-unmatched-pattern --fix
   
   # 3) prettier --write — MUST be last, because organize-imports-cli uses
   #    4-space indentation and drops trailing commas; prettier restores them
   #    to the repo's 2-space + trailing-comma style. Reversing the order
   #    leaves CI with a dirty diff.
   cat /tmp/src_files.txt \
     | xargs ./node_modules/.bin/prettier \
         --config './.prettierrc.yaml' --ignore-path './.prettierignore' \
         --write
   

   Core-components has no organize-imports-cli wired up — skip step 1 there.

3. Check the diff from the repo root:

   git status --short
   git diff --stat
   

   If git status --short is empty you're done. Otherwise commit the reformatting diff as its own Fix UI checkstyle commit, matching the existing history for bot-triggered formatting-only commits — unless the user asked you to fold it into the in-progress commit.

Out of scope

• TypeScript type-check errors (tsc) — different jobs, different failure modes, not auto-fixable by this skill.
• Java formatting — use the java-checkstyle skill (mvn spotless:apply).
• Python formatting — use make py_format (black + isort + pycln).
