TODO Next: MCP without the schema tax (phi meta-tools)
- mcpExpose=phi|direct|auto on RawConfig + MCPConfig; phi default keeps direct as a measured option for small servers (2-tool cheaper direct) - src/mcp.ts: buildMcpMetaTools + phi branch in connectMcp: lazy list/inspect/call behind 3 fixed schemas instead of N per-tool schemas; direct branch kept; bindMcpGuard wires permission+PluginHost guard for MCP calls through the same gate as built-ins - prompt mcpServers names-only under phi; under direct schemas travel as before — 20-tool server ~2750 tok -> ~phi (names) until mcp_call - session: isDirect mcpServerNames non-enumerable marker, activeTools hides mcp_call from pre-wired rules when inside mcp_call, /tools shows mcp_call and Enabled/Withheld reflects the 3 meta-names under phi - permission: mcp_* as read (free), mcp_call mutating keyed by server.tool, same top-level suppression + ask-to-approve as other mutating tools - cli: bindMcpGuard + /mcp list shows exposure + mcp_* listed; headless denies line mentions mcp_list - commit.ts: git_commit_message kept in git set via toolSetOf/ disabledToolNames overlay Tests: 798 pass, 0 fail; tsc exit 0; mcp.test.ts covers phi stays empty until mcp_call and direct still namespaced.

3. **MCP tanpa schema tax** — phi 3 meta-tools mcp_list/mcp_inspect/mcp_call, prompt hanya nama server, permission+guard lewat built-in, keep direct registration untuk server 2-tool. Test: server 20-tool 0 schema sampai mcp_call.

4. **Subagent parallelism** — task terima beberapa investigations, run Promise.all dengan panel fan-out, test overlap waktu.

5. **Undo a turn** — snapshot file-tool edits pre-prompt (cap 100), /undo restores files+conversation atau keduanya, /redo, bash tidak ter-snapshot (docs), test edit reverted + record hilang.
|
||||
6. **Maintenance polish** — pricing source+date, estimateTokens label everywhere /cost, listPaths notice staleness / refresh, MUTATING derive dari #2.
