The marketplace.json plugin source used {"source": "github", "repo":
"jrenaldi79/harness-engineering"} which points back to the same repo that
hosts the marketplace. This caused Claude Code to recursively clone the repo
into its own cache directory (harness-engineering/1.0.0/harness-engineering/
1.0.0/...) until the path exceeded filesystem limits.
Fix: change the source to a relative path ("./") since the plugin lives at
the marketplace root. Also add self-referential source detection to the
marketplace schema test and a cache recursion check to the E2E install test.

Summary\n\n- Fix
marketplace.jsonself-referential GitHub source that caused recursive caching andENAMETOOLONGerrors during plugin install\n- Change plugin source from{\"source\": \"github\", \"repo\": \"jrenaldi79/harness-engineering\"}to\"./\"(relative path)\n- Add self-referential source detection to marketplace schema test\n- Add cache recursion nesting check to E2E install test\n\n## Root Cause\n\nThe marketplace and plugin lived in the same repo, butmarketplace.jsonused a GitHub object source pointing back to itself. Claude Code would clone the repo into its cache, find the.claude-plugin/marketplace.jsoninside, and recursively clone again — creatingharness-engineering/1.0.0/harness-engineering/1.0.0/...until the path exceeded filesystem limits.\n\n## Test plan\n\n- [x] Marketplace schema test passes (227/227 unit tests green)\n- [x] Schema test now detects self-referential GitHub sources\n- [x] Schema test now accepts relative path strings (\"./\")\n- [ ] Users clear cache (rm -rf ~/.claude/plugins/cache/harness-engineering) and reinstall plugin\n\nhttps://claude.ai/code/session_01JQrEpoK2PjaQ55CTFkHxy6
