+# Governance
+
+How this marketplace is maintained, what you can expect from upstream, and how it's meant to be used.
+
+## TL;DR
+
+- Solo-maintained, AI-assisted development, MIT licensed.
+- **Fork-and-own is the default model.** Upstream is a starting point, not a vendor.
+- Issues welcome as signals. Pull requests are not accepted — see [Why no PRs](#pull-requests--no).
+- No SLA. Best-effort bug fixes and security advisories. Breaking changes happen and are noted in each plugin's CHANGELOG.
+
+---
+
+## Can I trust this?
+
+Be honest with yourself about what you're adopting:
+
+- **One maintainer.** If I get hit by a bus, the bus wins. The repos stay up under MIT, but no one owes you a fix.
+- **AI-generated code with human review.** Every plugin is built through dialog-driven development with Claude Code. I read, test, and judge the output before it ships, but I'm not auditing every line the way a security firm would. Treat it accordingly.
+- **No commercial interests.** I'm not selling a SaaS, not steering you toward a paid tier, not collecting telemetry. The plugins run locally in your Claude Code installation.
+- **MIT licensed.** Fork it, modify it, ship it under your own name.
+
+If you work somewhere that needs vendor accountability, support contracts, or signed assurances — **this isn't that.** Use it as a reference implementation, fork it into your own organization, and own the result.
+
+---
+
+## How this is meant to be used
+
+### Fork-and-own
+
+The intended workflow:
+
+1. **Fork** the marketplace (or a single plugin) into your own organization or namespace.
+2. **Tailor** it to your context — terminology, integrations, whatever doesn't fit out of the box.
+3. **Maintain it yourself.** Treat your fork as the canonical version for your team.
+4. **Watch upstream selectively.** Cherry-pick changes that help, ignore changes that don't. There's no obligation to stay in sync.
+
+For `claude-design` specifically, the most likely fork is a content adaptation — different intent-preset coverage (e.g., dropping `frontier-design` if your team never uses it), an organization-specific DESIGN.md template, a different evidence-grade discipline, or per-preset prompt patterns tuned to your team's design system. The plugin is a content surface plus a single skill. Forking it is straightforward.
+
+### What to change first when you fork
+
+- **Identity** — rename the plugin, replace authorship, update README.
+- **Reference content** — the `references/` tree reflects what Anthropic published and the community converged on as of 2026-05-17. Adjust to your team's house style and design system.
+- **Frontmatter** — `name` and `description` show up in `/config`. Pick names that won't collide with other forks installed on the same machine.
+
+### Staying current with upstream
+
+If you want to pull in upstream changes later:
+
+- **Cherry-pick, don't merge.** Each plugin moves independently.
+- **Read the CHANGELOG first.**
+- **Keep your customizations distinct.** A renamed skill (`my-org-design-facilitator`) merges more cleanly than edits to `claude-design-facilitator`.

+
+## What upstream provides
+
+| | What I do | What I don't |
+|---|---|---|
+| **Bug fixes** | Best-effort when I notice or get a clear report | No SLA, no triage commitment |
+| **Security issues** | Investigate within reasonable time, document in CHANGELOG | No CVE process, no embargo coordination |
+| **New features** | When they fit my own usage | Not on request |
+| **Breaking changes** | Documented in CHANGELOG | They happen — version pin if you need stability |
+| **Compatibility** | Tracked against current Claude Code releases | No long-term support branches |
+
+If any of this is a dealbreaker — fork now, version-pin, and stop reading upstream.
+

+
+## How to contribute
+
+### Issues — yes, please
+
+Issues are the most valuable thing you can send me:
+
+- **Bug reports** with reproduction steps. Even a screenshot helps.
+- **Use-case feedback.** "I tried to use this in my organization and X didn't fit" is genuinely useful, even if I can't fix it for you.
+- **Content suggestions.** If a reference file in `claude-design` produces guidance that doesn't match what you observe in `claude.ai/design` today, tell me what you saw. Concrete examples beat abstract complaints.
+
+### Pull requests — no
+
+This is deliberate, not laziness:
+
+- **Solo review is a bottleneck.** Honest PR review takes me longer than rewriting from scratch. The math doesn't work.
+- **Forks are where the value is.** The fork-and-own model means upstream consolidation isn't the point. Your organization's adaptations belong in your fork, not mine.
+- **AI-generated code complicates provenance.** Every line here is produced through dialog with Claude Code, with me as the judge. Mixing in PRs from contributors with different processes and licensing assumptions creates a mess I'd rather not untangle.
+
+If you've built something useful on top of a fork, **publish it under your own name and link back.** I'll happily list notable forks here once they exist.
+
+### Notable forks
+
+*(To be populated as forks emerge. If you've forked this plugin for production use, open an issue and I'll add a link.)*

+
+## Relationship between plugins
+
+These plugins are **independent**. Install one without the others, fork one without the others. They share conventions (slash command naming, hook patterns, AI-generated disclosure, and the shared `human-friendly-style` output style) but no runtime dependencies.
+
+`claude-design` is a content surface with a single skill — it works without any other plugin installed. It recommends Anthropic's official `knowledge-work-plugins/design` as the downstream tool for post-design critique, accessibility audit, and engineering handoff, but does not depend on it being present.
+
+The marketplace is a **catalog**, not a suite. Don't fork the whole repo unless you actually want to maintain everything.
+
+---
+
+## Versioning and stability
+
+- **Semantic versioning per plugin.** Each plugin has its own `CHANGELOG.md` and version number.
+- **Breaking changes happen.** I bump the major version when they do, but I don't run an LTS branch.
+- **Pin your version.** If stability matters more than features, install a specific version and stay there until you choose to upgrade.
+
+For `claude-design` specifically: changes to skill trigger behavior or per-preset reference content schema are minor or major bumps. Pure documentation or per-preset content refresh from Anthropic source updates are patch. The skill surface itself is meant to be stable across patch releases.
