spotless-fixA skill your agent uses when fixing code formatting errors, ktlint violations, or style issues.
Spotless Fix is an agent skill from MartinStyk/apk-analyzer. Use when fixing code formatting errors, ktlint violations, or style issues. Run after generating or modifying Kotlin files. Triggered by phrases like "fix formatting", "spotless", "ktlint error", "formatting violation", "fix code style", "run spotless".
Its SKILL.md is about 760 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Mobile, covering Android development and Linting and formatting. It works with Kotlin. The repository describes itself as: The most downloaded APK analysis app on Google Play. Detailed reports of every app on your device. No root, no ads, nothing leaves the phone. The licence is GPL-3.0.
5 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit d807559. It shows what the files ask for, not the result of running them.
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.
No scripts in the folder and no shell commands in SKILL.md (its code samples are kotlin and bash).
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Spotless Fix loads about 756 tokens when it runs. Until then it costs about 67 tokens; SKILL.md has 149 words of instructions outside code blocks.
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.
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.

A skill your agent uses when fixing code formatting errors, ktlint violations, or style issues. Spotless Fix is an agent skill from MartinStyk/apk-analyzer. Use when fixing code formatting errors, ktlint violations, or style issues.
Spotless Fix fits situations like: fixing code formatting errors; ktlint violations.
Run `npx skills add MartinStyk/apk-analyzer --skill spotless-fix -a claude-code`. Or copy the skill folder (.claude/skills/spotless-fix in MartinStyk/apk-analyzer) into .claude/skills/spotless-fix in your project. Claude Code loads it when a task matches its description.
Run `npx skills add MartinStyk/apk-analyzer --skill spotless-fix -a codex`. Or copy the skill folder (.claude/skills/spotless-fix in MartinStyk/apk-analyzer) into .agents/skills/spotless-fix in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add MartinStyk/apk-analyzer --skill spotless-fix -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/spotless-fix, .gemini/skills/spotless-fix, .github/skills/spotless-fix and .opencode/skills/spotless-fix in your project.
SKILL.md names no scripts, command-line tools or credentials: Spotless Fix is instructions for the agent only.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Spotless Fix is published under the GPL-3.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 756 tokens (SKILL.md is roughly 3k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
