Describes how the VSCode extension will support multiple ACP agents:
- Settings schema storing registry-format AgentConfig entries
- Built-in agents (Claude Code, Codex, Gemini) as defaults
- Import agents from ACP registry with automatic updates
- Spawn-time resolution: npx → pipx → binary download
- Binary caching in ~/.symposium/bin/{id}/{version}/
Co-authored-by: Claude <[email protected]>
Add agent registry system that supports multiple distribution methods
(npx, pipx, binary) and merges built-in agents with user settings.
New agentRegistry.ts module provides:
- AgentConfig interface matching registry format
- Three built-in agents: zed-claude-code, zed-codex, google-gemini
- Distribution resolver (npx → pipx → binary with caching)
- Platform detection for binary downloads
- Binary caching at ~/.symposium/bin/{id}/{version}/
Settings changes:
- symposium.agents now uses distribution-based schema (breaking change)
- symposium.currentAgentId replaces symposium.currentAgent
- Built-ins live in code, settings only stores overrides/additions

- Add fetchRegistry() and fetchAvailableRegistryAgents() to fetch from GitHub releases URL - Add addAgentFromRegistry() to save registry entries to settings with _source: 'registry' - Add showAddAgentFromRegistryDialog() with QuickPick UI showing available agents (filters out already-configured ones) - Register symposium.addAgentFromRegistry command - Add '+ Add agent from registry...' link in settings view Co-authored-by: Claude <[email protected]>
- Registry JSON is { version, agents: [...] }, not a direct array
- Binary distribution uses 'archive' and 'cmd', not 'url' and 'executable'
- Add version display next to agent names in settings view

- Add checkForRegistryUpdates() that fetches registry and updates any _source: 'registry' agents with newer versions - Add '↻ Check for updates' link in settings view - Shows progress notification while checking - Reports which agents were updated or if all are current Co-authored-by: Claude <[email protected]>
Remove enableSparkle and enableCrateResearcher settings from the VSCode extension. All Symposium components (Sparkle, Ferris) are now always enabled - the only user choice is which backend agent to use. - Remove settings from package.json - Remove Components section from Settings webview - Simplify AgentConfiguration class - Remove outdated CLI flags from agent spawning - Update tests to remove references to removed settings - Update symposium-acp-agent README to reflect current state Co-authored-by: Claude <[email protected]>
- Add 'eliza' subcommand to symposium-acp-agent that runs elizacp directly - Add 'symposium' distribution type for built-in agents - Add ElizACP to built-in agents list - Update test workspace to use elizacp as default agent - Refactor agent spawning to handle symposium builtins without wrapping Co-authored-by: Claude <[email protected]>
