The `--detach` flag is a bolt-on that spawns a child process by reconstructing CLI argv — brittle and not composable.\n\nThe goal is to decompose into three primitives (Docker-style):\n- **`fabro create`** — allocate run, persist spec, return run ID\n- **`fabro start`** — spawn a detached engine process (always a separate process)\n- **`fabro attach`** — tail progress.jsonl with live rendering + handle interviews\n\nCompositions:\n- `fabro run` = create + start + attach (attach opens the file before start, guaranteeing zero missed events)\n- `fabro run --detach` = create + start + print run ID\n- Standalone `fabro attach ` = reconnect to any running/finished run\n\n## Key design decisions\n\n### 1. Attach absorbs `run_progress.rs`\nThe existing `ProgressUI` (indicatif spinners, stage tracking, tool call rendering) moves into `attach`. Rather than building a new renderer, we add a `handle_json_line(&str)` method to ProgressUI that parses JSONL envelopes and dispatches to the same internal rendering methods (`on_stage_started`, `finish_stage`, `on_tool_call_started`, etc.). This preserves 100% rendering fidelity.\n\nThe dispatch pattern already exists in `format_event_pretty()` in `logs.rs` — match on the `\"event\"` string field, extract typed values from JSON. The internal ProgressUI methods already take simple types (strings, ints), not `WorkflowRunEvent`.\n\n`handle_event(&WorkflowRunEvent)` stays for any in-process callers (API server).\n\n### 2. File-based interview IPC\nThe engine process uses a new `FileInterviewer` (impl Interviewer) that:\n- Writes `interview_request.json` (serialized `Question`) to run_dir\n- Polls for `interview_response.json` in run_dir\n- Deserializes the `Answer`, cleans up both files\n\nThe attach loop watches for `interview_request.json`:\n1. Hides indicatif bars (same as `ProgressAwareInterviewer` does today)\n2. Prompts user via `ConsoleInterviewer` logic\n3. Writes `interview_response.json`\n4. Shows bars again\n\n`Question` and `Answer` already derive `Serialize`/`Deserialize`.\n\n### 3. RunSpec persistence\n`create` writes `spec.json` to run_dir — a serializable struct with all CLI args needed to run the engine. Replaces the argv-reconstruction in `detach_run()`.\n\n### 4. Engine invocation\n`start` spawns `fabro _run_engine --run-dir ` — a hidden internal command that reads `spec.json` and executes the workflow. The child uses `FileInterviewer` instead of `ConsoleInterviewer`.\n\n### 5. Stdin and Ctrl+C\n- `fabro run` (foreground): Ctrl+C sends SIGTERM to child (via `run.pid`), waits for conclusion, then exits\n- `fabro attach` (standalone): Ctrl+C just detaches, run continues\n- Engine process stdin is always `/dev/null` — interviews go through file-based IPC, not stdin\n\n---\n\n## Implementation plan\n\n### Phase 1: Foundation — RunSpec + extract engine\n\n**Step 1: RunSpec struct**\n- New file: `lib/crates/fabro-workflows/src/run_spec.rs`\n- `#[derive(Serialize, Deserialize)]` struct: run_id, workflow_path (absolute), dot_source, working_directory, goal, model, provider, sandbox_provider, labels, verbose, no_retro, ssh, preserve_sandbox, dry_run, auto_approve, resume, run_branch\n- Methods: `save(run_dir)`, `load(run_dir)`\n- Register in `lib/crates/fabro-workflows/src/lib.rs`\n\n**Step 2: FileInterviewer**\n- New file: `lib/crates/fabro-interview/src/file.rs`\n- `FileInterviewer { run_dir: PathBuf }` implementing `Interviewer`\n- `ask()`: write `interview_request.json`, poll for `interview_response.json` (100ms interval, respect timeout from Question), deserialize Answer, clean up files\n- Register in `lib/crates/fabro-interview/src/lib.rs`\n\n**Step 3: Extract `run_engine()` from `run_command()`**\n- Modify: `lib/crates/fabro-cli/src/commands/run.rs`\n- New function: `run_engine(spec, run_dir, run_defaults, styles, github_app, git_author) -> Result<()>`\n- Contains lines ~629–end of current `run_command()`: EventEmitter + JSONL writer + cost accumulator + git SHA tracker, sandbox creation, engine execution, conclusion writing, retro, PR creation, cleanup\n- Does NOT register ProgressUI — only writes progress.jsonl\n- Uses `FileInterviewer` instead of `ConsoleInterviewer`/`ProgressAwareInterviewer`\n\n**Step 4: Hidden `_run_engine` command**\n- Modify: `lib/crates/fabro-cli/src/main.rs`\n- Add `_RunEngine { run_dir: PathBuf }` to `Command` enum (hidden)\n- Handler: load `spec.json`, load cli_config/github_app/git_author, call `run_engine()`\n\n### Phase 2: Attach — ProgressUI from JSONL + interview handling\n\n**Step 5: Add `handle_json_line` to ProgressUI**\n- Modify: `lib/crates/fabro-cli/src/commands/run_progress.rs`\n- New method: `handle_json_line(&mut self, line: &str)` that parses envelope JSON and dispatches to existing internal methods:\n - `\"Sandbox.Initializing\"` / `\"Sandbox.Ready\"` → `on_sandbox_event()`\n - `\"SetupStarted\"` / `\"SetupCompleted\"` → `on_setup_started/completed()`\n - `\"StageStarted\"` → `on_stage_started(node_id, name, script)`\n - `\"StageCompleted\"` → extract fields, call `finish_stage()`\n - `\"StageFailed\"` → `finish_stage()` + error info\n - `\"Agent.ToolCallStarted\"` / `\"Agent.ToolCallCompleted\"` → `on_tool_call_started/completed()`\n - `\"Agent.AssistantMessage\"` → update stage model display\n - `\"Agent.CompactionCompleted\"` → compaction bar\n - `\"ParallelBranchStarted\"` / `\"ParallelBranchCompleted\"` → branch tracking\n - `\"RetroStarted\"` / `\"RetroCompleted\"` / `\"RetroFailed\"` → retro spinner\n - `\"SshAccessReady\"` → SSH command display\n - etc.\n- Follows the same pattern as `format_event_pretty()` in `logs.rs` but calls internal rendering methods instead of formatting strings\n\n**Step 6: Attach command**\n- New file: `lib/crates/fabro-cli/src/commands/attach.rs`\n- `attach_run(run_dir, kill_on_detach: bool) -> Result`:\n 1. Read `spec.json` for header info (run_id, workflow name)\n 2. Create ProgressUI, show header (version, run_id, time, run_dir)\n 3. Poll loop (100ms):\n - Read new lines from `progress.jsonl`, feed to `progress_ui.handle_json_line()`\n - Check for `interview_request.json` → hide bars, prompt via ConsoleInterviewer, write `interview_response.json`, show bars\n - Exit when `conclusion.json` exists and no new lines\n 4. Read `conclusion.json` for exit code: Success/PartialSuccess → 0, else → 1\n- Ctrl+C: if `kill_on_detach`, SIGTERM to child PID from `run.pid`; otherwise print \"Detached\" and exit 0\n- Add `Attach { run: String, verbose: bool }` to `Command` enum\n- Handler: `run_lookup::resolve_run()`, call `attach_run()`\n\n### Phase 3: Create + Start commands\n\n**Step 7: Create command**\n- New file: `lib/crates/fabro-cli/src/commands/create.rs`\n- `create_run(args, run_defaults, styles) -> Result<(String, PathBuf)>`:\n - Extract lines ~440–627 from `run_command()`: resolve workflow, parse graph, validate, resolve sandbox/model/provider, create run_dir, write graph.fabro/id.txt/status.json(Submitted)/spec.json\n - Returns (run_id, run_dir)\n- Add `Create` variant to `Command` enum (same args as RunArgs minus --detach/--run-id/--run-dir)\n\n**Step 8: Start command**\n- New file: `lib/crates/fabro-cli/src/commands/start.rs`\n- `start_run(run_dir, inherit_stdin: bool) -> Result` (returns child PID):\n - Validate status.json is `Submitted`\n - Spawn `fabro _run_engine --run-dir ` as detached child (setsid, stdout/stderr → detach.log, stdin → /dev/null)\n - Write child PID to `run.pid`\n - Return PID\n- Add `Start { run: String }` to `Command` enum\n- Handler: resolve run, call `start_run()`\n\n### Phase 4: Recompose `fabro run`\n\n**Step 9: Rewrite `run_command()` as composition**\n- `fabro run` (foreground):\n ```\n let (run_id, run_dir) = create_run(args, ...)?;\n let _child_pid = start_run(&run_dir)?;\n let exit_code = attach_run(&run_dir, kill_on_detach=true)?;\n std::process::exit(exit_code);\n ```\n- `fabro run --detach`:\n ```\n let (run_id, run_dir) = create_run(args, ...)?;\n start_run(&run_dir)?;\n println!(\"{run_id}\");\n ```\n- Delete `detach_run()` from main.rs\n- Deprecate `--run-id` / `--run-dir` hidden flags\n\n### Phase 5: Cleanup + testing\n\n**Step 10: Tests**\n- `run_spec.rs`: save/load roundtrip\n- `file.rs` (FileInterviewer): write request → write response → verify ask() returns correct answer\n- `run_progress.rs`: test `handle_json_line` with sample JSONL lines (stage started/completed, tool calls, etc.)\n- `attach.rs`: integration test — write JSONL lines to a temp file, verify attach loop renders and exits correctly\n- Existing tests remain unchanged\n\n**Step 11: Remove dead code**\n- Delete `detach_run()` from main.rs\n- Remove `--run-id` / `--run-dir` args from RunArgs\n- `ProgressAwareInterviewer` moves into attach.rs (or gets deleted if attach handles the coordination directly)\n\n---\n\n## Files summary\n\n| File | Action |\n|------|--------|\n| `lib/crates/fabro-workflows/src/run_spec.rs` | **New** — RunSpec struct |\n| `lib/crates/fabro-workflows/src/lib.rs` | Modify — register run_spec module |\n| `lib/crates/fabro-interview/src/file.rs` | **New** — FileInterviewer |\n| `lib/crates/fabro-interview/src/lib.rs` | Modify — register file module |\n| `lib/crates/fabro-cli/src/commands/create.rs` | **New** — create logic extracted from run.rs |\n| `lib/crates/fabro-cli/src/commands/start.rs` | **New** — spawn detached engine process |\n| `lib/crates/fabro-cli/src/commands/attach.rs` | **New** — attach loop + interview handling |\n| `lib/crates/fabro-cli/src/commands/run_progress.rs` | Modify — add `handle_json_line()` method |\n| `lib/crates/fabro-cli/src/commands/run.rs` | Modify — extract run_engine(), rewrite run_command() as composition |\n| `lib/crates/fabro-cli/src/commands/mod.rs` | Modify — register new modules |\n| `lib/crates/fabro-cli/src/main.rs` | Modify — add Command variants, delete detach_run() |\n\n## Verification\n\n1. `cargo build --workspace` — compiles\n2. `cargo test --workspace` — all existing + new tests pass\n3. `cargo clippy --workspace -- -D warnings` — clean\n4.

Here's a summary of what was fixed:\n\n## Summary of Fixes\n\n1. **Deduplicated 5 helper functions** (`create.rs` → imports from `run.rs`): `resolve_cli_goal`, `apply_goal_override`, `parse_sandbox_provider`, `resolve_sandbox_provider`, `resolve_model_provider` were copied verbatim into `create.rs`. Made the `run.rs` versions `pub(crate)` and replaced the copies with imports. **(-92 lines)**\n\n2. **Eliminated `ProgressAwareInterviewer` hide/show duplication**: Removed the private `hide_bars()`/`show_bars()` methods that duplicated `ProgressUI::hide_bars/show_bars`. The `ask()` and `inform()` methods now call through the public `ProgressUI` methods via the mutex lock.\n\n3. **Removed unnecessary `Arc>` from `attach.rs`**: `ProgressUI` is only accessed from the main loop (single-threaded), so the `Arc>` wrapping was unnecessary overhead. Changed to bare `ProgressUI` with `&mut` access. Updated `drain_remaining` accordingly.\n\n4. **Cached PID in attach loop**: The PID file was re-read and parsed every 100ms iteration. Now the PID is read once and cached in `cached_pid: Option`.\n\n5. **Removed redundant `exists()` in `FileInterviewer`**: Replaced `if path.exists() { read_to_string() }` with direct `read_to_string()` + match on `ErrorKind::NotFound`. Eliminates an extra filesystem stat syscall per poll iteration.\n\n6. **Avoided `.cloned()` on arguments Value**: In `handle_json_line`, the tool call arguments JSON tree was being deep-cloned. Changed to borrow with `unwrap_or(&empty)` since `on_tool_call_started` takes `&Value`.\n\n7. **Fixed TOCTOU in `start.rs`**: Replaced `exists()`-then-load patterns with direct load + match on result. Status validation now does `RunStatusRecord::load()` directly and matches errors gracefully. Spec validation now calls `RunSpec::load()` directly.\n\n8. **Simplified `RunSpec → RunArgs` sandbox mapping**: Added `From for CliSandboxProvider` (reverse of existing conversion), replacing the 15-line exhaustive match with `.map(CliSandboxProvider::from)`.\n\n9. **Derived `PartialEq` on `RunSpec`**: Replaced 17 field-by-field `assert_eq!` calls in the roundtrip test with a single `assert_eq!(loaded, spec)`.\n\n10. **Fixed missing newline at EOF** in `fabro-interview/Cargo.toml`.", - "internal.thread_id": "implement", + "internal.thread_id": "simplify_opus", "internal.retry_count.toolchain": 1, "command.stderr": "", "command.output": "", @@ -139,13 +143,26 @@ "notes": "Script completed: cargo clippy -q --workspace -- -D warnings 2>&1", "duration_ms": 12221 }, + "simplify_gpt": { + "status": "fail", + "failure": { + "message": "LLM error: Not found on anthropic: model: gpt-54", + "failure_class": "deterministic", + "failure_signature": "api_deterministic|anthropic|not_found" + }, + "duration_ms": 471 + }, "start": { "status": "success", "duration_ms": 0 } }, - "next_node_id": "simplify_gpt", + "next_node_id": "verify", + "loop_failure_signatures": { + "simplify_gpt|deterministic|api_deterministic|anthropic|not_found": 1 + }, "node_visits": { + "simplify_gpt": 1, "toolchain": 1, "preflight_lint": 1, "start": 1, diff --git a/nodes/simplify_gpt/prompt.md b/nodes/simplify_gpt/prompt.md new file mode 100644 index 000000000..db1dee1d1 --- /dev/null +++ b/nodes/simplify_gpt/prompt.md @@ -0,0 +1,271 @@ +Goal: # Decompose `fabro run` into `create` / `start` / `attach` + +## Context + +`fabro run` currently does everything in a single process: creates the run directory, sets up the event system, builds the sandbox, runs the workflow engine, writes the conclusion, and renders live progress.

Parameter sprawl: adding new parameters to a function instead of generalizing or restructuring existing ones +3.

Missed concurrency: independent operations run sequentially when they could run in parallel +3. Hot-path bloat: new blocking work added to startup or per-request/per-render hot paths +4.
