## Why The initial research pass focused on agent definitions. An audit identified critical and minor gaps in both doc sets around plugin publishing, marketplace registration, and the Copilot extensibility model. ## Implementation Notes Claude Code gaps filled: end-to-end publish walkthrough (scaffold → validate → tag → host → register), CLI vs in-session command surface equivalence, all six marketplace source URL formats, plugin update/upgrade lifecycle, interactive plugin manager UI, private marketplace auth, `commands` vs `skills/` distinction. Copilot gaps filled: discovered that the GitHub App-based Copilot Extensions track was sunset November 2025. Created copilot-extensions.md as historical reference (deprecated, with MCP servers as the current replacement path). Documented the agent vs. skillset extension type distinction, OAuth install flow, and VS Code Chat Participants as the surviving @mention mechanism. overview.md updated with a "Which Track to Use" decision table covering all four active tracks plus the deprecated one.
