0.5

What's new in 0.5

Self-updating skills

• Every skill's pre-flight update check is now consent-gated self-install. When a skill detects it's behind the manifest, it offers to update itself — on agreement, it downloads the .skill from the latest release and unpacks it over the installed skill directory. The unpack path is resolved from where the running skill lives, so this works for any agent whose skills directory is writable, not just Claude Code.
• All skills bumped a minor to carry the new flow: astro-seo → 0.6, readability-check → 0.5, the rest → 0.4.

Astro SEO skill

• Updated for @jdevalk/astro-seo-graph 1.1.1 and 1.2.0.
• 1.1.1 bug fixes folded in. validateInternalLinks now recognises public/ assets as valid link targets (the skip callback trims back to just SSR-only routes and dynamic params), and validateMetadataLength no longer truncates descriptions at raw apostrophes — both workarounds removed.
• 1.2.0 markdown alternates. New Should in category 6 (agent discovery): serve clean .md copies of every page for AI agents. Integration example enables markdownAlternate: true (gated on wiring the route first), and a new Phase 2 subsection covers createMarkdownEndpoint, route-before-discovery-link ordering, Cloudflare Transform Rules for Accept: text/markdown content negotiation, and the renderMarkdownAlternate export.

Repository

• Reframed as agent skills rather than Claude Code-specific — repo tagline, README intro, and the self-install flow all drop the Claude Code hardcoding.
• .claude/ session state is now gitignored.

Install

Download the .skill file for the skill you want and open it — Claude installs it automatically. Or, for any agent that supports the skills format, unzip the .skill (or clone the repo) and copy the skill folder into your agent's skills directory. Once installed, the skill will offer to keep itself up to date.
