From ddea00b03d1db89f6e43c8f1b8f089a4ef613713 Mon Sep 17 00:00:00 2001 From: Pranit Date: Tue, 1 Sep 2026 02:10:17 -0400 Subject: [PATCH 01/21] Simplify subagent delegation Replace the general manager with direct one-off and named persistent delegation. Keep child sessions private to their parent and route approvals through the normal parent surface. Remove the Ctrl-X manager, hosted child terminal, relationship graph, queues, notifications, and delivery envelopes. --- AGENTS.md | 4 +- CONTRIBUTING.md | 4 +- README.md | 2 + scripts/pgso/corpus.json | 1 - scripts/pgso/tests/test_corpus.py | 5 +- src/acp/prompt.zig | 45 +- src/acp/sessions.zig | 4 +- src/builtins/tools.zig | 25 +- src/core/agent/runtime/config.zig | 1 + src/core/agent/runtime/orchestrator.zig | 135 +- src/core/agent/worker_runtime.zig | 15 + src/core/app/app_agent_runtime.zig | 4 + src/core/app/app_callbacks.zig | 46 +- src/core/app/app_commands.zig | 34 +- src/core/app/app_entry_runtime.zig | 4 +- src/core/app/app_input_runtime.zig | 489 +- src/core/app/app_lifecycle.zig | 324 - src/core/app/app_render_runtime.zig | 1883 +-- src/core/app/app_session_runtime.zig | 21 +- src/core/app/app_terminal_runtime.zig | 27 - .../app/app_terminal_takeover_runtime.zig | 1247 -- src/core/app/app_worker_runtime.zig | 108 +- src/core/app/input_approval_runtime.zig | 778 +- .../app/input_full_transcript_runtime.zig | 281 +- src/core/app/input_subagent_runtime.zig | 1069 -- src/core/cli/cli_ask.zig | 113 +- src/core/input/input_action.zig | 4 - src/core/session/session_discovery.zig | 14 - src/core/session/session_store.zig | 283 +- src/core/shared/profile_paths.zig | 9 + src/core/subagent/agent_adapter.zig | 87 +- src/core/subagent/agent_config.zig | 397 + src/core/subagent/approval_persistence.zig | 850 -- src/core/subagent/approval_registry.zig | 1357 +- src/core/subagent/authority.zig | 620 +- src/core/subagent/child_state.zig | 789 + src/core/subagent/communication.zig | 6053 -------- src/core/subagent/communication_manager.zig | 1100 -- src/core/subagent/communication_store.zig | 2378 --- src/core/subagent/control_store.zig | 2796 ---- src/core/subagent/create_store.zig | 1157 -- src/core/subagent/domain.zig | 1853 +-- src/core/subagent/execution.zig | 8365 +---------- src/core/subagent/input_action.zig | 52 - src/core/subagent/managed_owner.zig | 355 + src/core/subagent/manager.zig | 11935 ---------------- src/core/subagent/model_contract.zig | 360 +- .../subagent/parent_delivery_projector.zig | 1841 --- src/core/subagent/relationship_index.zig | 1419 -- src/core/subagent/resume_admission.zig | 987 +- src/core/subagent/tool_host.zig | 7999 +---------- src/core/subagent/ui_projection.zig | 2728 ---- src/core/subagent/work_events.zig | 196 - src/core/terminal/engine.zig | 142 - src/core/tooling/tool_runtime.zig | 969 +- src/core/workspace/context_contract.zig | 4 +- src/main.zig | 132 +- src/tools/agent/subagent.zig | 32 +- src/ui/footer/input_presentation.zig | 89 +- src/ui/footer/paint_plan.zig | 40 - src/ui/footer/render_input.zig | 43 - src/ui/footer/surface_frame.zig | 34 +- src/ui/input/runtime.zig | 278 +- src/ui/input/terminal_action_decoder.zig | 52 - src/ui/resize_tests.zig | 5 - src/ui/shell_runtime.zig | 10 - src/ui/subagent/controller.zig | 657 - src/ui/subagent/runtime.zig | 9011 ------------ tests/e2e/acp.test.ts | 820 +- tests/e2e/ci-shard-weights.json | 1 - tests/e2e/file-tool-paths.test.ts | 210 - tests/e2e/gateway-stream-lifecycle.test.ts | 300 +- tests/e2e/tui-command-permissions.test.ts | 1005 +- .../e2e/tui-gateway-stream-lifecycle.test.ts | 2797 ---- tests/e2e/tui-subagent-manager.test.ts | 5853 -------- tests/e2e/tui-terminal-tool.test.ts | 149 - 76 files changed, 3686 insertions(+), 81600 deletions(-) delete mode 100644 src/core/app/app_terminal_takeover_runtime.zig delete mode 100644 src/core/app/input_subagent_runtime.zig create mode 100644 src/core/subagent/agent_config.zig delete mode 100644 src/core/subagent/approval_persistence.zig create mode 100644 src/core/subagent/child_state.zig delete mode 100644 src/core/subagent/communication.zig delete mode 100644 src/core/subagent/communication_manager.zig delete mode 100644 src/core/subagent/communication_store.zig delete mode 100644 src/core/subagent/control_store.zig delete mode 100644 src/core/subagent/create_store.zig delete mode 100644 src/core/subagent/input_action.zig create mode 100644 src/core/subagent/managed_owner.zig delete mode 100644 src/core/subagent/manager.zig delete mode 100644 src/core/subagent/parent_delivery_projector.zig delete mode 100644 src/core/subagent/relationship_index.zig delete mode 100644 src/core/subagent/ui_projection.zig delete mode 100644 src/core/subagent/work_events.zig delete mode 100644 src/ui/subagent/controller.zig delete mode 100644 src/ui/subagent/runtime.zig delete mode 100644 tests/e2e/tui-subagent-manager.test.ts diff --git a/AGENTS.md b/AGENTS.md index db2667f0a..8d66683d3 100644 --- a/AGENTS.md +++ b/AGENTS.md @@ -128,7 +128,7 @@ Config precedence (highest wins): Project `.fx.json` accepts only repo-safe defaults: `sandbox`, `max_agent_steps`, `max_tool_result_bytes`, and `context`.

Run `fx mcp add NAME COMMAND [ARGS...]` for a local server or `fx mcp add --transport http NAME URL` for Streamable HTTP without opening the interactive shell; the equivalent `/mcp add` forms remain available inside fx. A workspace may also provide Claude-compatible `.mcp.json` with a top-level `mcpServers` object. Pending project servers stay disconnected on every surface until they are approved with `/mcp trust approve ` or `fx mcp trust approve `. Interactive fx presents the trust prompt after startup. `fx ask` reports skipped pending servers on stderr, and ACP leaves them unavailable. Repository files cannot persist approval or expose environment-expanded values before approval. `/mcp trust reject ` rejects one and `/mcp trust reset` clears the workspace choices. Profile entries win same-name collisions. Profile `~/.fx/mcp.json` accepts `mcpServers` as an alias for `mcp`, while writes always use `mcp` and ambiguous server-like keys produce a visible warning. Project instruction files may link within their scope, and read-only workspace or compatibility skill directories and their primary `SKILL.md` files may link within their owning workspace or home; managed skills, secondary resources, and escaping links remain no-follow. Skills installed via symlinks that resolve outside home or workspace (e.g. Nix store paths) are loaded when their resolved target is inside a directory listed in the `FX_SKILL_SYMLINK_AUTHORITIES` environment variable (colon-separated absolute paths). `fx status` and `fx doctor` report invalid or suspicious trusted MCP profiles without starting their servers. +The `subagent` tool has four operations: `run` delegates one temporary task, `message` creates or continues a named persistent agent, `wait` observes a child, and `stop` cancels its current work. Persistent agents are configured with strict profile-owned JSON files at `~/.fx/agents/.json`; child sessions remain private to their saved parent session. + Use `fx mcp list`, `fx mcp path`, and `fx mcp remove NAME` for noninteractive profile management. `fx mcp trust approve|reject NAME`, `fx mcp trust approve-all`, and `fx mcp trust reset` manage workspace-scoped project trust. `fx mcp auth NAME` and `fx mcp logout NAME` run the existing remote credential lifecycle without opening the TUI or contacting the Gateway. MCP servers have a 30-second startup timeout by default; set `startup_timeout_ms` on a server when its cold start needs a different bound. For direct `docker run` stdio entries, fx uses a private container ID file to remove the owned container after shutdown or startup failure. A configuration that already supplies `--cidfile` keeps ownership of its own cleanup policy. diff --git a/scripts/pgso/corpus.json b/scripts/pgso/corpus.json index 8f4a1b39d..2933335a0 100644 --- a/scripts/pgso/corpus.json +++ b/scripts/pgso/corpus.json @@ -107,7 +107,6 @@ {"name": "e2e-tui-resume-brutal", "argv": ["bun", "test", "--max-concurrency", "1", "./tui-resume-brutal.test.ts"], "test_file": "tui-resume-brutal.test.ts"}, {"name": "e2e-tui-permissions", "argv": ["bun", "test", "--max-concurrency", "1", "./tui-permissions.test.ts"], "test_file": "tui-permissions.test.ts"}, {"name": "e2e-tui-interrupt-recovery", "argv": ["bun", "test", "--max-concurrency", "1", "./tui-interrupt-recovery.test.ts"], "test_file": "tui-interrupt-recovery.test.ts"}, - {"name": "e2e-tui-subagent-manager", "argv": ["bun", "test", "--max-concurrency", "1", "./tui-subagent-manager.test.ts"], "test_file": "tui-subagent-manager.test.ts"}, {"name": "e2e-tui-terminal-tool", "argv": ["bun", "test", "--max-concurrency", "1", "./tui-terminal-tool.test.ts"], "test_file": "tui-terminal-tool.test.ts"}, {"name": "e2e-tui-native-clear-recovery", "argv": ["bun", "test", "--max-concurrency", "1", "./tui-native-clear-recovery.test.ts"], "test_file": "tui-native-clear-recovery.test.ts"}, {"name": "e2e-tui-gateway-stream-lifecycle", "argv": ["bun", "test", "--max-concurrency", "1", "./tui-gateway-stream-lifecycle.test.ts"], "test_file": "tui-gateway-stream-lifecycle.test.ts"} diff --git a/scripts/pgso/tests/test_corpus.py b/scripts/pgso/tests/test_corpus.py index 6ddab15e5..b4dbc63f0 100644 --- a/scripts/pgso/tests/test_corpus.py +++ b/scripts/pgso/tests/test_corpus.py @@ -46,7 +46,6 @@ "tui-resume-brutal.test.ts", "tui-permissions.test.ts", "tui-interrupt-recovery.test.ts", - "tui-subagent-manager.test.ts", "tui-terminal-tool.test.ts", "tui-native-clear-recovery.test.ts", "tui-gateway-stream-lifecycle.test.ts", @@ -365,8 +364,8 @@ def test_production_manifest_classifies_every_e2e_file(self) -> None: EXCLUDED_E2E_TESTS, tuple(test_file for test_file, _ in corpus.intentional_exclusions), ) - self.assertEqual(36, len(corpus.scenarios)) - self.assertEqual(53, len(corpus.candidate_scenarios)) + self.assertEqual(35, len(corpus.scenarios)) + self.assertEqual(52, len(corpus.candidate_scenarios)) self.assertEqual( { "direct-help": 100, diff --git a/src/acp/prompt.zig b/src/acp/prompt.zig index f3b0e721f..1d8439fa6 100644 --- a/src/acp/prompt.zig +++ b/src/acp/prompt.zig @@ -33,7 +33,6 @@ const subagent_agent_adapter = @import("../core/subagent/agent_adapter.zig");
