Four Free Claude Code Skills for Prompt Clarity, Tutorials, and Bug Hunting
A Reddit user shared four free Claude Code skills (Apache 2.0, no paid tier) built while developing Stuffolio, a Universal iOS/iPadOS/macOS app. Each skill is available with sample outputs on GitHub.
prompter
Rewrites your Claude Code prompt for clarity before execution. It resolves ambiguous references like “that file” to a file path, sharpens vague verbs, and restructures stacked questions. Crucially, it skips rewriting when the prompt is already clear, avoiding friction on simple prompts. Includes worked examples across 8 categories.
tutorial-creator
Turns a file from your own project into an annotated reading tutorial with vocabulary tracking, pre- and post-tests, and prerequisite gap analysis. Language-agnostic — works with any codebase. Sample outputs: a starter walkthrough and a more advanced one.
bug-echo
After you fix a bug, bug-echo reads your fix, confirms the anti-pattern, then scans the entire codebase for other instances of the same error. Each match is read in context and classified as BUG / OK / REVIEW. It honors #if os(...) blocks, so Universal codebases don’t get false positives across platforms. Sample report from a real run.
bug-prospector
Forward-looking audit that runs 7 analysis lenses: assumptions, state machines, boundaries, data lifecycle, error paths, time-dependent bugs, and platform divergence. It asks upfront whether the project is iOS, macOS, or Universal so findings respect your platform set. Works well combined with bug-echo: run prospector before releases, echo after prospector fixes. Sample report.
Who it's for: Developers using Claude Code on multi-platform or complex codebases who want automated prompt refinement, codebase-wide bug detection, and pre-release auditing.
