Thirteen Claude skills built like software, not prompt snippets

What it does

ClaudeSkills curates thirteen end-to-end workflows for Claude Code, packaged as portable skills that drop into the agent’s skills directory. The flagship set produces complete deliverables—consulting-style slide decks, cited decision briefs, product requirement documents, and publishable articles—while the remaining skills handle tasks like security audits, architecture reviews, and pair programming. Each workflow is a structured directory, not a single prompt, and is invoked via slash command.

The interesting bit

The project applies software engineering discipline to prompt templates: every skill carries checkable acceptance criteria, explicit boundaries for when not to use it, and pitfall tables drawn from real failures. There are 85 routing evaluation cases proving skills trigger correctly, plus CI gates on every push. The deck skill even submits to blind judging; the current pipeline scored 7.1/10, crossing the professional design-studio threshold.

Key highlights

• deck-studio offers seventeen reusable visual styles (Bauhaus, Constructivist, Neubrutalism, Aicher) that act as rendered seeds rather than generated-from-scratch layouts
• Blind evaluation trajectory for decks: 6.0 → 6.6 → 6.6 → 7.1, with the latest pipeline beating its predecessor by a 42% margin in a three-judge swap test
• Nine of the thirteen curated skills ship zero code; the security matrix explicitly flags that only one can delete files and it defaults to dry-run
• Routing evals across ten skills prevent misfires—each skill must prove it triggers when it should and defers when it shouldn’t
• Experimental skills live in lab/ and graduate into the curated set only after passing structure, routing, and compile checks

Caveats

• Quality gates are self-audits run by Claude, not independent third-party certification; the README explicitly notes you should re-run the validation scripts yourself
• Installed skills are file copies rather than references, so updating after pulling new commits requires manual re-installation
• The mineru-pdf-parser skill depends on a separate local MinerU installation that is not bundled

Verdict

Worth a look if you use Claude Code daily and want repeatable, versioned workflows for professional output. If you are not using a skills-compatible agent, this is just a folder of very elaborate prompts you cannot easily run.
