Selection\n\n## Context\n\nEdge selection is currently fully deterministic — ties broken by highest weight then lexical node ID. This adds a `selection=\"random\"` node attribute so outgoing edges use weighted-random tiebreaking instead. The cascade priority (conditions → preferred label → suggested next → unconditional → fallback) is unchanged; randomness only replaces the pick-one-from-candidates step. Validation rejects `selection=\"random\"` combined with conditional edges.\n\n## Approach: Red/Green TDD\n\nWrite failing tests first, then write the minimum code to make them pass. Each step below is a red→green cycle. Run `cargo test -p fabro-workflows` after each change.\n\n---\n\n### Step 1: RED — `Node::selection()` accessor tests\n\nAdd tests to `graph/types.rs` `mod tests`:\n- `node_selection_default`: `Node::new(\"x\").selection()` == `\"deterministic\"` → fails (method doesn't exist)\n- `node_selection_random`: node with `selection=\"random\"` attr → `selection()` == `\"random\"` → fails\n\n### Step 2: GREEN — `Node::selection()` accessor\n\nAdd to `Node` impl in `graph/types.rs` (~after `backend()`, line 236):\n```rust\npub fn selection(&self) -> &str {\n self.str_attr(\"selection\").unwrap_or(\"deterministic\")\n}\n```\n\n---\n\n### Step 3: RED — `weighted_random` tests\n\nAdd tests to `engine.rs` `mod tests`:\n- `weighted_random_empty_returns_none` → fails (function doesn't exist)\n- `weighted_random_single_edge` → fails\n- `weighted_random_zero_weight_all_selected`: 200 trials, both targets seen at least once → fails\n- `weighted_random_high_weight_dominates`: weight 100 vs 1, 500 trials, heavy >90% → fails\n\n### Step 4: GREEN — `weighted_random` function\n\nAdd after `best_by_weight_then_lexical` (~line 386) in `engine.rs`:\n- `weight <= 0` treated as 1 for probability calculation\n- Uses `rand::thread_rng()` (already imported at line 11)\n- Manual weighted sampling loop\n\n---\n\n### Step 5: RED — `select_edge` with `selection` param tests\n\nUpdate all ~8 existing `select_edge` tests to pass `\"deterministic\"` as 5th arg → fails (signature mismatch).\n\nAdd new tests:\n- `select_edge_random_returns_some_edge`: two unconditional edges, `selection=\"random\"` → fails\n- `select_edge_random_preferred_label_still_wins`: preferred label overrides random → fails\n\n### Step 6: GREEN — `select_edge` signature + `pick_edge` dispatcher\n\n**a)** Add `pick_edge` dispatcher:\n```rust\nfn pick_edge<'a>(edges: &[&'a Edge], selection: &str) -> Option<&'a Edge> {\n match selection {\n \"random\" => weighted_random(edges),\n _ => best_by_weight_then_lexical(edges),\n }\n}\n```\n\n**b)** Add `selection: &str` param to `select_edge`, replace 3 `best_by_weight_then_lexical` calls (lines 411, 442, 446) with `pick_edge(..., selection)`.\n\n**c)** Update 2 call sites to pass `node.selection()`:\n- Line 1548 (skip by StageStart hook)\n- Line 1759 (normal execution)\n\n---\n\n### Step 7: RED — validation rule tests\n\nAdd tests to `validation/rules.rs` `mod tests`:\n- `random_selection_no_conditions_clean`: random node + unconditional edges → no diagnostics → fails (rule doesn't exist)\n- `random_selection_with_conditions_errors`: random node + conditional edge → 1 Error diagnostic → fails\n- `deterministic_selection_with_conditions_ok`: deterministic node + conditional edges → no diagnostics → fails\n\n### Step 8: GREEN — validation Rule 23\n\nAdd `RandomSelectionNoConditionsRule` struct + `LintRule` impl:\n- Iterates nodes with `selection()==\"random\"`, checks outgoing edges for conditions\n- Error severity, message: `Node '{id}' has selection=\"random\" but also has conditional edges; random selection and conditions cannot be combined`\n- Fix: `Remove the condition attributes from outgoing edges, or remove selection=\"random\" from the node`\n- Register in `built_in_rules()` vec (line 35)\n\n---\n\n### Step 9: Docs (no TDD cycle)\n\n**`docs/workflows/transitions.mdx`:**\n- Update intro paragraph (line 6): `\"deterministic by default\"`, link to random selection section\n- Add \"Random selection\" section after \"Weight tiebreaking\" (~after line 157) with DOT example and `` about validation constraint\n\n**`docs/reference/dot-language.mdx`:**\n- Add `selection` row to \"All nodes\" attribute table (~line 191)\n\n---\n\n### Step 10: Final verification\n\n1. `cargo test -p fabro-workflows` — all tests pass\n2. `cargo clippy --workspace -- -D warnings` — clean\n3. `cargo fmt --check --all` — formatted\n\n## Files\n\n| File | Change |\n|---|---|\n| `lib/crates/fabro-workflows/src/graph/types.rs` | `selection()` accessor + tests |\n| `lib/crates/fabro-workflows/src/engine.rs` | `weighted_random`, `pick_edge`, modify `select_edge` sig + call sites + tests |\n| `lib/crates/fabro-workflows/src/validation/rules.rs` | Rule 23 +

The cascade priority (conditions → preferred label → suggested next → unconditional → fallback) is unchanged; randomness only replaces the pick-one-from-candidates step. Validation rejects `selection="random"` combined with conditional edges. + +## Approach: Red/Green TDD + +Write failing tests first, then write the minimum code to make them pass.

Fix any issues found. + +## Phase 1: Identify Changes + +Run git diff (or git diff HEAD if there are staged changes) to see what changed. If there are no git changes, review the most recently modified files that the user mentioned or that you edited earlier in this conversation. + +## Phase 2: Launch Three Review Agents in Parallel + +Use the Agent tool to launch all three agents concurrently in a single message. Pass each agent the full diff so it has the complete context. + +### Agent 1: Code Reuse Review + +For each change: + +1. Search for existing utilities and helpers that could replace newly written code. Use Grep to find similar patterns elsewhere in the codebase — common locations are utility directories, shared modules, and files adjacent to the changed ones. +2. Flag any new function that duplicates existing functionality. Suggest the existing function to use instead. +3. Flag any inline logic that could use an existing utility — hand-rolled string manipulation, manual path handling, custom environment checks, ad-hoc type guards, and similar patterns are common candidates. + +### Agent 2: Code Quality Review + +Review the same changes for hacky patterns: + +1. Redundant state: state that duplicates existing state, cached values that could be derived, observers/effects that could be direct calls +2. Parameter sprawl: adding new parameters to a function instead of generalizing or restructuring existing ones +3. Copy-paste with slight variation: near-duplicate code blocks that should be unified with a shared abstraction +4. Leaky abstractions: exposing internal details that should be encapsulated, or breaking existing abstraction boundaries +5. Stringly-typed code: using raw strings where constants, enums (string unions), or branded types already exist in the codebase + +### Agent 3: Efficiency Review + +Review the same changes for efficiency: + +1. Unnecessary work: redundant computations, repeated file reads, duplicate network/API calls, N+1 patterns +2. 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. Unnecessary existence checks: pre-checking file/resource existence before operating (TOCTOU anti-pattern) — operate directly and handle the error +5. Memory: unbounded data structures, missing cleanup, event listener leaks +6. Overly broad operations: reading entire files when only a portion is needed, loading all items when filtering for one + +## Phase 3: Fix Issues + +Wait for all three agents to complete. Aggregate their findings and fix each issue directly. If a finding is a false positive or not worth addressing, note it and move on — do not argue with the finding, just skip it. + +When done, briefly summarize what was fixed (or confirm the code was already clean). \ No newline at end of file diff --git a/nodes/simplify/provider_used.json b/nodes/simplify/provider_used.json new file mode 100644 index 000000000..c1905ff10 --- /dev/null +++ b/nodes/simplify/provider_used.json @@ -0,0 +1,5 @@ +{ + "mode": "agent", + "provider": "anthropic", + "model": "claude-opus-4-6" +} \ No newline at end of file diff --git a/nodes/simplify/response.md b/nodes/simplify/response.md new file mode 100644 index 000000000..57daa9d95 --- /dev/null +++ b/nodes/simplify/response.md @@ -0,0 +1,17 @@ +All tests pass, clippy clean, fmt clean. Here's a summary: + +## Summary of fixes + +### Fixed +1. **Missing trailing newlines** in `docs/workflows/transitions.mdx` and `docs/reference/dot-language.mdx` — both files ended without a final newline, which `git diff` flagged as `\ No newline at end of file`. Added the trailing newlines. + +2. **No validation for unknown `selection` attribute values** — A typo like `selection="randon"` would silently fall through to deterministic behavior via the `_ =>` catch-all in `pick_edge`. Added `SelectionValidRule` (following the existing `DirectionValidRule` pattern) that emits a Warning when a node has an unrecognized `selection` value. Added 3 tests for the new rule. + +3. **Formatting** — `cargo fmt` fixed minor formatting in the new rule code. + +### Not fixed (false positives / not worth addressing) +- **5th parameter on `select_edge`**: Could be derived from `node_id + graph`, but the explicit parameter is better for testability (tests pass `"random"`/`"deterministic"` directly without building full node objects). Consistent with how the function already receives `node_id` separately from `graph`. +- **`weighted_random` could use `rand::distributions::WeightedIndex`**: The hand-rolled version is clear, short, and correct. `WeightedIndex` would save ~5 lines but add an import and slightly different error handling. Not worth the churn. +- **`Vec` allocation in `weighted_random`**: For typical edge counts (2-5), this is negligible overhead on a path that's dominated by LLM calls. No concern. +- **Stringly-typed `selection`**: The codebase consistently uses string attributes for similar features (`retry_policy`, `backend`, `fidelity`). The new `SelectionValidRule` catches typos at validation time, making this safe. +- **Doc comment placement on `EdgeSelection`**: Pre-existing issue, not introduced by this diff. \ No newline at end of file diff --git a/nodes/simplify/status.json b/nodes/simplify/status.json new file mode 100644 index 000000000..20798bafb --- /dev/null +++ b/nodes/simplify/status.json @@ -0,0 +1,6 @@ +{ + "status": "success", + "notes": "Stage completed: simplify", + "failure_reason": null, + "timestamp": "2026-03-15T23:10:16.655369+00:00" +} \ No newline at end of file
