What this adds or changes

Makes the repository a plugin marketplace, so a stack installs (and later updates) without copying files.

• .claude-plugin/marketplace.json: one entry per stack, "source": "./stacks/<id>". Entries set no component fields, so each stack's .minimax-plugin/plugin.json stays the single definition of its skills. This file name is read by MiniMax Code's user-added marketplaces, Claude Code and Codex.
• scripts/check.mjs:
  • marketplace: one entry per stack under stacks/ and community/, named after the directory, same description as plugin.json, no skills/commands/... fields;
  • version bump (when CHECK_BASE is set): a stack whose files changed since the merge base must raise its plugin.json version. Marketplace installs compare versions to decide whether an update is available, so a change without a bump never reaches people who installed the stack.
• CI checks out full history and passes the PR base SHA as CHECK_BASE (empty on pushes to main, which skips the bump check).
• README / README_ZH: new "from the marketplace" install option (MiniMax Code desktop Plugins → Add marketplace, Claude Code /plugin marketplace add). The existing note that mcode plugin add only installs from the official catalog stays. CONTRIBUTING (both languages), stacks/README.md and the template README describe the marketplace entry and the version rule.

Note: adding marketplaces in MiniMax Code is still rolling out (test/internal channels first); the README says so.

Check output

$ MINIMAX_CODE_DIR=../minimax-code CHECK_BASE=origin/main node scripts/check.mjs
validate-plugin: stacks/ronny passed the public Plugin V1 checks.
validate-plugin: templates/stack-template passed the public Plugin V1 checks.
check: 2 stack(s) passed: stacks/ronny, templates/stack-template

Negative cases run locally, each fails as expected:

• edit a ronny skill without a bump → version 0.2.0 is not higher than 0.2.0; bump to 0.2.1 → passes;
• entry with "skills" and a different description → two errors;
• entry removed → stacks/ronny has no entry.

Real usage record

Loaded this repository with MiniMax Code's own marketplace code (readCatalog + inspectRelativeEntry + EntryMaterializer from local-runtime-v2): catalog mcode-stack parses with no diagnostics; ronny resolves to its .minimax-plugin manifest, version 0.2.0, 15 skills, and stages an install copy.

Not verified: an end-to-end install in Claude Code (its CLI is killed at startup on the test machine).

If this skill were deleted, where would the agent go wrong?

Not a skill. Without the marketplace, installing a stack means copying a directory by hand, and installed copies never learn about updates.
