v0.1.0 — the repository becomes the Skilder plugin

First release of the Skilder plugin, the entry point to a Skilder workspace for any AI agent.

What is in it

• Two manifests, one tree. plugin.json + mcp.json (Agent Plugins 1.0: Codex, Copilot, Cursor, VS Code, Kiro), .claude-plugin/plugin.json + .mcp.json (Claude), gemini-extension.json, and a one-plugin marketplace for Claude (.claude-plugin/marketplace.json) and for Codex (.agents/plugins/marketplace.json).
• Skills. using-skilder 1.0.0: the entry protocol (start with init_skilder, learn the plugin then the skill, the session id on every call, read vs write, files, MCP Apps, feedback, what each refusal means). connect-to-skilder 2.1.0: recognises the plugin's own server, never adds a duplicate. import-skills-to-skilder 2.0.0: disclosure template.
• Claude Code and Cowork. /skilder <task> and two shell hooks under claude/: a line of context at session start, and the session id remembered per project for a resumed conversation. No network, no permission change.
• CI. Manifests agree and equal the tag; wording lint; hooks exercised; claude plugin validate --strict; OpenAI package built; Snyk agent-scan when SNYK_TOKEN is set.
