Host Capability Matrix

This matrix is the durable contract for what LemonCrow expects from each supported host. Use it when deciding whether a workflow should rely on native host surfaces, LemonCrow's MCP wrapper, or a shell fallback.

Trace metadata fields used across this matrix:

• trace_confidence
• capture_sources
• missing_surfaces

Confidence legend: full_live, mcp_live, wrapper_live, imported, manual.

Capability Matrix

Host	Native surfaces LemonCrow uses	MCP	Hooks / events	Wrapper	Routing enforcement	Trace confidence	Unsupported controls	Fallback
Claude Code	AGENTS.md, plugin agent prompt, CLI session exports	Yes, via lc mcp --host claude	Plugin hooks plus importable session artifacts	Shell install script plus generated host prompt	Medium: prompt-level guidance plus MCP mode controls	full_live when hooks + MCP are both present; otherwise mcp_live, imported, or manual	No native IDE task wiring beyond plugin surfaces	Use shell tasks and imported traces if live capture is unavailable
Codex CLI	AGENTS.md, session imports, generated host instructions	Yes, via lc mcp --host codex	Plugin lifecycle hooks (SessionStart, UserPromptSubmit, PostToolUse, Stop)	Shell installer and generated instructions	Medium-high: MCP guidance plus trusted lifecycle hooks	mcp_live, wrapper_live, imported, or manual	Hooks require explicit trust after install or changes; no guaranteed editor task bridge	Fall back to lc CLI plus imported session history
Cursor	MCP config, project-local rules	Yes, via lc mcp --host cursor	No durable native hook bus; relies on MCP-only path	Shell installer and rules file	Medium: MCP constraints plus project rules	mcp_live or manual	No global rules system, no CLI for detection, MCP cwd != workspace root	Use lc CLI and imported Cursor agent session traces
Copilot	MCP config, Copilot instructions, agent, VS Code tasks	Yes, via VS Code MCP config	Task runner events only; no deep per-tool hook callbacks	VS Code task + instruction wrapper	Medium-high inside agent; shell tasks remain advisory	mcp_live, wrapper_live, or manual	No direct MCP invocation from tasks.json; limited background lifecycle visibility	Use lc CLI tasks, worktree bootstrap, and runtime evidence capture
opencode	Generated agent markdown, session imports, local DB ingestion	Yes, via lc mcp --host opencode	Local chat.message plugin for prompt-time nudges	Shell installer, generated agent file, and local plugin	Medium: prompt plugin + MCP constraints	mcp_live, imported, or manual	Plugin API has no Codex-style /hooks status screen or editor task plumbing	Fall back to imported traces and direct lc CLI commands
Hermes Agent	YAML config ($HERMES_HOME/config.yaml), toolset registration	Yes, via lc mcp --host hermes	No durable native hook bus	Shell installer and YAML config merge	Medium: MCP constraints plus toolset registration	mcp_live or manual	No CLI version check, no global rules system, YAML-only config	Use lc CLI and manual trace recording
Antigravity	Workspace AGENTS.md, Antigravity MCP config, agy companion CLI	Yes, via lc mcp --host antigravity	No durable native hook bus; wrapper boundaries via agy	Shell installer and generated Antigravity guidance	mcp_live, wrapper_live, or manual	No first-class hook/event API and limited native task orchestration	Use shell verification loops, wrapper traces, and explicit trace recording
