AI coding tools converge on portable skills

samber/cc-skills-golang turns Go coding workflows into portable markdown skills, one of more than 1,600 cross-tool libraries now living on GitHub. Not a one-off.

That's the real shift: the reusable unit in AI coding is moving from prompts and MCP configs to markdown skills. Those skills already cross Claude Code, Cursor, Codex, and Gemini. Build a workflow once and it doesn't get stranded when your team switches editors.

DeerFlow is one example already living this way. The coding harness now ships with skills built in.

Google folding agent skills into its own Workspace CLI is the strongest signal yet that platform vendors are settling on this format too.

My take: MCP tool servers narrow to stateful integrations while markdown skills become the format teams actually reuse across every coding tool. Package your own workflows as skills instead of tool-specific configs, and they'll follow you the next time you switch tools. Watch whether the count keeps climbing past 1,600, and whether more platform vendors follow Google instead of leaving this to community repos.

The tell this week: Google picked up the same pattern instead of leaving it to community maintainers. That's usually the sign a format is moving from convention to default.
