At a glance

Runs detekt, checkstyle, and Android lint together, reads their reports, and proposes approved fixes grouped by file.

  • Works in 7 steps: Detect the main branch → Run all three checks in parallel → Read the reports → …
  • Checking a branch's changes for detekt, checkstyle, and lint issues
  • SKILL.md covers Steps and Important Rules
  • Calls git

What it does

This skill detects the repository's main branch automatically, falling back to checking for trunk or main directly, then runs all three Gradle quality tasks in parallel and lets each finish even if another fails, before parsing every generated HTML report into a file, line, rule, and message per issue.

It filters the combined issue list down to files actually changed on the current branch, using the merge base with the detected main branch, or reports every issue when run directly on that branch. It proposes a specific fix per issue grouped by file, shows current versus proposed code, and waits for the user to approve which fixes to apply before changing anything, respecting the project's line-length limit and Kotlin conventions.

When your agent uses it

  • Checking a branch's changes for detekt, checkstyle, and lint issues
  • Reviewing code quality issues before opening a pull request
  • Getting proposed fixes for lint warnings in changed files

Example prompts

  • “Run all three code quality checks on my current branch.”
  • “Show me proposed fixes for the lint issues in my changed files.”
  • “Check if trunk has any outstanding checkstyle issues.”

Requirements

  • Gradle
  • detekt, checkstyle, and Android lint configured in the project

Workflow steps

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

  1. Detect the main branch
  2. Run all three checks in parallel
  3. Read the reports
  4. Filter to relevant issues
  5. Present a summary
  6. Propose fixes
  7. Ask for approval

What it can do on your machine

Read from SKILL.md and the folder at commit ceafcdc. 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

Android Code Quality Checker loads about 587 tokens when it runs. Until then it costs about 32 tokens; SKILL.md has 281 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~32
When it runs · the whole SKILL.md, loaded when a task matches
~587

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.

Code Check

Run all three code quality checks, read the reports, and propose fixes for any issues found.

Steps

1. Detect the main branch

Detect the main/default branch (typically trunk or main):

bash
git symbolic-ref refs/remotes/origin/HEAD 2>/dev/null \
  | sed 's@^refs/remotes/origin/@@'

If that fails, check if trunk or main exists and use whichever is found. Store this as <main-branch> for later steps.

2. Run all three checks in parallel

Run these Gradle tasks:

bash
./gradlew detekt
./gradlew checkstyle
./gradlew lintWordPressRelease

Run all three in parallel to save time. Allow each to complete even if others fail.

3. Read the reports

After the checks complete, read the generated report files:

  • Detekt: WordPress/build/reports/detekt/detekt.html
  • Checkstyle: WordPress/build/reports/checkstyle/checkstyle.html
  • Lint: WordPress/build/reports/lint-results-wordpressRelease.html

Parse each report to extract the list of issues (file, line, rule, message).

4. Filter to relevant issues

Focus on issues in files that were changed on the current branch. To determine changed files:

bash
git diff --name-only $(git merge-base <main-branch> HEAD)..HEAD

If no branch changes are detected (e.g., on trunk), report all issues found.

5. Present a summary

Output a summary table or grouped list of issues organized by tool:

  • Detekt issues (count and details)
  • Checkstyle issues (count and details)
  • Lint issues (count and details)

For each issue include the file path, line number, rule name, and the message.

6. Propose fixes

For each issue, propose a specific fix. Group fixes by file. Show the current code and what it should be changed to.

7. Ask for approval

Present the proposed fixes and ask the user which ones to apply before making any changes.

Important Rules

  • Do NOT make any code changes until the user approves.
  • Respect the project's code style (120-char line limit, Kotlin conventions, no empty lines after opening braces).
  • Use TODO instead of FIXME in any comments.
  • Do not suppress warnings unless the user explicitly approves.
