Here's a summary of what was fixed:\n\n## Summary\n\nThree fixes applied based on the review agents' findings:\n\n1. **Unified `send_to_segment` signature** (Quality, High) — Changed `send_to_segment` from taking `&Track` to taking `&Path`, matching `send_panic_to_sentry`'s signature. This moved the file-reading logic into the function itself, making both sender functions consistent and simplifying the `SendAnalytics` handler in `main.rs` from a 6-line async block to a single function call.\n\n2. **Removed redundant `release` in `ClientOptions`** (Quality, Low) — The Sentry event already carries `release` from `build_panic_event()`. Setting it again in `ClientOptions` was redundant (Sentry uses the event-level value when present). Simplified to `sentry::ClientOptions::default()`.\n\n3. **Used `crate::version::FABRO_VERSION`** (Reuse, Low) — Replaced raw `env!(\"CARGO_PKG_VERSION\")` in `panic.rs` with the existing `crate::version::FABRO_VERSION` constant for consistency with the rest of the codebase.\n\n**Skipped findings (not worth addressing):**\n- `panic_message()` duplication with `engine.rs` — Different crates, different prefixes, only 5 lines. Not worth cross-crate extraction.\n- `dirs::home_dir().join(\".fabro\")` repeated 15+ times — Valid but out of scope for this diff.\n- Stringly-typed subcommand names — clap requires string literals in attributes, so constants can only help 2 of 4 sites. Marginal benefit.\n- All efficiency findings — No issues found; code is well-structured for its fire-and-forget telemetry purpose.", "internal.retry_count.simplify_gpt": 1, "graph.model_stylesheet": "\n * { backend: api; model: claude-opus-4-6;}\n ", @@ -35,14 +37,15 @@ "internal.retry_count.simplify_gemini": 1, "thread.toolchain.current_node": "preflight_compile", "last_stage": "simplify_gpt", + "thread.simplify_gpt.current_node": "verify", "graph.goal": "# Add Sentry panic reporting to fabro CLI\n\n## Context\n\nFabro has no panic reporting.

Here's a summary of the review and fixes:\n\n## Review Summary\n\n### Issues Fixed\n\n1. **Missing `SENTRY_DSN` early check in `report_panic`** (`panic.rs` line 78-81): Added `if SENTRY_DSN.is_none() { return; }` at the top of `report_panic()`. This follows the same pattern as `sender.rs` which checks `SEGMENT_WRITE_KEY.is_none()` early in `send()`. Without this, a panic in a release build compiled without `SENTRY_DSN` would unnecessarily: capture a stacktrace, build a Sentry event, serialize it to JSON, write a temp file, and fork a subprocess — only for the subprocess to immediately error with \"SENTRY_DSN not set\".\n\n2. **Misleading doc comment on `send_panic_to_sentry`** (`panic.rs` line 110): Changed \"Reads the JSON event from `path`, sends it to Sentry, then deletes the file.\" to \"Reads the JSON event from `path` and sends it to Sentry.\" — the function doesn't delete the file; `main.rs` handles cleanup.\n\n### Reviewed and Clean (no issues)\n\n- **Code reuse**: `spawn_fabro_subcommand` correctly centralizes the temp-file-write + detached-subprocess pattern shared by both analytics and panic senders. The `dirs::home_dir().join(\".fabro\")` pattern is used ad-hoc across the codebase (no existing helper to reuse).\n- **Copy-paste**: The `SendAnalytics` and `SendPanic` handlers in `main.rs` are 3 lines each with different function calls — not worth abstracting further.\n- **Spawn logic**: The double-fork pattern is well-implemented and correctly isolated in `spawn.rs`. The existing `detach_run` in `main.rs` is a different use case (redirects to log files) so it doesn't make sense to share.\n- **Efficiency**: `install_panic_hook()` is a lightweight `take_hook + set_hook` — no startup overhead. The stacktrace capture in `build_panic_event` is expensive but only runs on actual panics. `sentry::init` in the subprocess is fine since it's a separate process.", - "current.preamble": "Goal: # Add Sentry panic reporting to fabro CLI\n\n## Context\n\nFabro has no panic reporting.

For each step, write the test first (red), then write the minimal code to make it pass (green).\n\n### Step 1: `spawn_detached` (fabro-util)\n- **Red**: Test that `spawn_detached` constructs the right args (unit-testable parts: temp file writing, arg assembly). On Unix, test the double-fork integration by spawning a real process that writes a marker file.\n- **Green**: Implement `spawn.rs` with fork/setsid/close_fd/fork/exec on Unix, DETACHED_PROCESS on Windows.\n\n### Step 2: Refactor `sender.rs` to use `spawn_detached`\n- **Red**: Existing `send_noops_without_write_key` test still passes. Add test verifying temp file is written with correct JSON.\n- **Green**: Replace `Command::spawn()` with `spawn_detached()`.\n\n### Step 3: `panic.rs` — event building\n- **Red**: Test `build_panic_event()` produces correct Sentry event structure (exception type, mechanism, level, stacktrace present).\n- **Green**: Implement event builder.\n\n### Step 4: `panic.rs` — hook + spawn\n- **Red**: Test that `report_panic` filters broken pipe. Test that it no-ops when telemetry is Off.\n- **Green**: Implement `install_panic_hook()`, `report_panic()`, `spawn_panic_sender()`.\n\n### Step 5: `panic.rs` — Sentry sender\n- **Red**: Test `send_panic_to_sentry` no-ops without DSN (like analytics no-ops without write key).\n- **Green**: Implement the `__send_panic` worker function.\n\n### Step 6: Wire up in `main.rs`\n- Add `__send_panic` subcommand + install panic hook.\n- Verify: `cargo build --workspace && cargo test --workspace && cargo clippy --workspace -- -D warnings`\n\n\n## Completed stages\n- **toolchain**: success\n - Script: `command -v cargo >/dev/null || { curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh -s -- -y && sudo ln -sf $HOME/.cargo/bin/* /usr/local/bin/; }; cargo --version 2>&1`\n - Stdout:\n ```\n cargo 1.94.0 (85eff7c80 2026-01-15)\n ```\n - Stderr: (empty)\n- **preflight_compile**: success\n - Script: `cargo check -q --workspace 2>&1`\n - Stdout: (empty)\n - Stderr: (empty)\n- **preflight_lint**: success\n - Script: `cargo clippy -q --workspace -- -D warnings 2>&1`\n - Stdout: (empty)\n - Stderr: (empty)\n- **implement**: success\n - Model: claude-opus-4-6, 89.1k tokens in / 13.5k out\n - Files: /home/daytona/workspace/lib/crates/fabro-cli/src/main.rs, /home/daytona/workspace/lib/crates/fabro-util/src/telemetry/mod.rs, /home/daytona/workspace/lib/crates/fabro-util/src/telemetry/panic.rs, /home/daytona/workspace/lib/crates/fabro-util/src/telemetry/sender.rs, /home/daytona/workspace/lib/crates/fabro-util/src/telemetry/spawn.rs\n- **simplify_opus**: success\n - Model: claude-opus-4-6, 60.2k tokens in / 17.7k out\n - Files: /home/daytona/workspace/Cargo.toml, /home/daytona/workspace/lib/crates/fabro-util/Cargo.toml, /home/daytona/workspace/lib/crates/fabro-util/src/telemetry/panic.rs, /home/daytona/workspace/lib/crates/fabro-util/src/telemetry/sender.rs, /home/daytona/workspace/lib/crates/fabro-util/src/telemetry/spawn.rs\n- **simplify_gemini**: success\n - Model: claude-opus-4-6, 54.4k tokens in / 12.4k out\n - Files: /home/daytona/workspace/lib/crates/fabro-cli/src/main.rs, /home/daytona/workspace/lib/crates/fabro-util/src/telemetry/panic.rs, /home/daytona/workspace/lib/crates/fabro-util/src/telemetry/sender.rs\n- **simplify_gpt**: success\n - Model: claude-opus-4-6, 56.8k tokens in / 12.7k out\n - Files: /home/daytona/workspace/lib/crates/fabro-util/src/telemetry/panic.rs\n", "command.stderr": "" }, "logs": [], @@ -149,6 +153,15 @@ "notes": "Script completed: cargo check -q --workspace 2>&1", "duration_ms": 72559 }, + "verify": { + "status": "success", + "context_updates": { + "command.output": "────────────\n Nextest run ID d32b87cc-218a-476b-b60a-ca5e7239c905 with nextest profile: default\n Starting 3416 tests across 38 binaries (183 tests skipped)\n────────────\n Summary [ 12.552s] 3416 tests run: 3416 passed, 183 skipped\n", + "command.stderr": "" + }, + "notes": "Script completed: cargo clippy -q --workspace -- -D warnings 2>&1 && cargo nextest run --cargo-quiet --workspace --status-level fail 2>&1", + "duration_ms": 74686 + }, "toolchain": { "status": "success", "context_updates": { @@ -190,11 +203,12 @@ "duration_ms": 305654 } }, - "next_node_id": "verify", + "next_node_id": "fmt", "node_visits": { "toolchain": 1, "simplify_opus": 1, "start": 1, + "verify": 1, "preflight_compile": 1, "simplify_gemini": 1, "preflight_lint": 1, diff --git a/nodes/simplify_gpt/diff.patch b/nodes/simplify_gpt/diff.patch new file mode 100644 index 000000000..2b87c833c --- /dev/null +++ b/nodes/simplify_gpt/diff.patch @@ -0,0 +1,24 @@ +diff --git a/lib/crates/fabro-util/src/telemetry/panic.rs b/lib/crates/fabro-util/src/telemetry/panic.rs +index 2cad1c3..2503d33 100644 +--- a/lib/crates/fabro-util/src/telemetry/panic.rs ++++ b/lib/crates/fabro-util/src/telemetry/panic.rs +@@ -76,6 +76,10 @@ fn is_broken_pipe(message: &str) -> bool { + + /// Report a panic to Sentry.
