Add git-subdir source type support to plugin marketplace schema #3376
Description
Describe the feature or problem you'd like to solve
/plugin marketplace add anthropics/claude-plugins-official fails with ~40 plugins.N.source: Invalid input errors because Copilot CLI's marketplace schema doesn't accept the git-subdir source type used widely in the Claude Code plugin ecosystem.
Proposed solution
No response
Example prompts or workflows
Example of a rejected entry (valid in Claude Code, rejected by Copilot CLI):
{
"name": "stripe",
"source": {
"source": "git-subdir",
"url": "https://github.com/stripe/ai.git",
"path": "providers/claude/plugin",
"ref": "main",
"sha": "ec93d4c4b9ffdbc994ac45ce692d4ec1cdb755f0"
}
}
Currently only string paths and {"source": "url", "url": "...", "sha": "..."} (whole-repo) are accepted. Without git-subdir support, ~40 of ~170 plugins in Anthropic's
official marketplace — including AWS, Stripe, Zapier, Shopify, Microsoft Dataverse, SAP, Auth0, Airtable, Expo, Railway, Neon, Snowflake, ServiceNow, and others — cannot be
installed via Copilot CLI. Please add git-subdir to the accepted source schema for plugin marketplace entries so the Claude Code ecosystem works out of the box.

Thanks for the request. As of Copilot CLI v1.0.102, plugin marketplaces accept
git-subdirplugin sources (and long plugin descriptions), so marketplaces such asanthropics/claude-plugins-officialthat use them should no longer fail withsource: Invalid inputerrors. If any entries still fail validation on the latest version, please reopen with the error output.Triaged as part of a Copilot SDK backlog review, with help from GitHub Copilot.
