Six skills I built for Claude Code - repo coherence, air-gapped debugging, and sorting my shopping list into aisle order
I've been building skills to fix things that kept biting me. Six of them, all MIT and free to try, no paid tier and nothing to sign up for.
**dovetail** \- checks whether a repo still agrees with itself. Dead links, dangling anchors, orphaned files, docs that drifted from the code, conventions the repo states but doesn't follow. The deterministic half is plain Python with no network and no model, so it runs fast enough to gate a build.
**heliograph** \- debug a machine you can't log into, through an operator who can't debug it. A git repo is the transport in both directions. For air-gapped and change-controlled estates.
**verve** \- strips AI tells from prose, British English. Explicitly not a detector-evasion tool, and it says so if you ask it to be one.
**legwork** \- research where every claim states how well it's supported, and says when the evidence can't settle the question.
**outlook-graph** \- Microsoft 365 mail and calendar via Graph, plus PST archives into searchable markdown.
**trello** \- boards, lists and cards, plus board digests and a due-date radar. The pack also has the one I use most and expected least: it reorders a shopping list into the aisle order of an actual supermarket, prefixing a food-type emoji to every card, so you walk the shop once instead of doubling back. Store layout comes from a preset - Tesco by default, any shop if you write one.
**How Claude helped:** all six were written with Claude Code, and the interesting part was that the skills started changing how the next one got built. Dovetail found stale docs in its own siblings. Verve got used on their READMEs. The format itself imposed discipline too, because a skill is loaded on its description alone - if you can't say what it does in two lines, it's badly scoped and you find that out immediately.
