Ásgeir Thor Johnson a7d0a2699d claude-code 2.1.248: add workflow-authoring skill, Workflow tool now points to it
- New skills/workflow-authoring/SKILL.md — the Workflow scripting reference (script API, resume, quality patterns, examples) moved out of the tool description into a skill
- Workflow tool description shrunk to opt-in rules + meta/pipeline example + "load the workflow-authoring skill"
- Artifact: CDN allowlist replaces the strict "self-contained only" CSP rule (cdnjs, jsdelivr, tailwind, jquery scripts; Google Fonts stylesheets); favicon required only on first publish; list shows favicon
- ListAgents wording tweak

Anthropic — which file is which product?

The bare claude-<model>.md files in this folder are the claude.ai system prompts — the prompt served to that model in the Claude web/mobile app (claude.ai). They are not API prompts (the Claude API injects no system prompt) and not Claude Code prompts.
