Skills for writing sanderling specs

Agent skills for adopting sanderling: getting it running against your app, writing property specifications, reviewing them for the failure modes that make a spec look like it works when it does not, and reading a run honestly.

Copy the ones you want into your agent's skills directory (.claude/skills/ for Claude Code) or point your agent at this directory directly.

Start with sanderling-setup, then sanderling-spec-authoring. Run sanderling-spec-review over anything before you trust it.

The reasoning behind the rules these encode is in docs/development/design-principles.md, section 8 in particular.
