-
-Building workflows from natural language sounds straightforward until you try to measure it. When a user says "send me a Slack message every morning with a summary of my unread emails," how do you evaluate whether the resulting workflow is correct? Is partial credit fair? What about workflows that are functionally equivalent but structurally different?
-
-We built Workflow Bench to answer these questions. This post covers why we needed a dedicated benchmark, how we designed it, and what the results tell us about the current state of natural language workflow building.
-
-## Why a Workflow Benchmark?
-
-<!-- TODO: Motivation for building Workflow Bench -->
-<!-- - Gap in existing benchmarks (code gen benchmarks don't capture workflow semantics) -->
-<!-- - Need to track progress as we iterate on the copilot / natural language builder -->
-<!-- - Workflows are structured artifacts, not just code — they have topology, block types, connections, configs -->
-
-## What We're Measuring
-
-<!-- TODO: Define the core evaluation dimensions -->
-<!-- - Structural correctness (right blocks, right connections) -->
-<!-- - Configuration accuracy (correct params, API mappings) -->
-<!-- - Functional equivalence (does it do the same thing even if shaped differently?) -->
-<!-- - Edge cases: loops, conditionals, parallel branches, error handling -->
-
-## Benchmark Design
-
-<!-- TODO: How the benchmark dataset is constructed -->
-<!-- - Task categories and complexity tiers -->
-<!-- - How ground truth workflows are defined -->
-<!-- - Natural language prompt variations (terse vs. detailed, ambiguous vs. precise) -->
-
-### Task Categories
-
-<!-- TODO: Break down the types of workflows in the benchmark -->
-<!-- - Simple linear (A → B → C) -->
-<!-- - Branching / conditional -->
-<!-- - Looping / iterative -->
-<!-- - Parallel fan-out / fan-in -->
-<!-- - Multi-trigger -->
-
-### Scoring
-
-<!-- TODO: Explain the scoring methodology -->
-<!-- - How partial credit works -->
-<!-- - Structural similarity metrics -->
-<!-- - Config-level accuracy -->
-<!-- - Overall composite score -->
-
-## Evaluation Pipeline
-
-<!-- TODO: How we run the benchmark end to end -->
-<!-- - Prompt → model → workflow JSON → evaluator → score -->
-<!-- - Automation and reproducibility -->
-<!-- - How we handle non-determinism across runs -->
-
-## Results
-
-<!-- TODO: Present the benchmark results -->
-<!-- - Model comparisons -->
-<!-- - Performance by task category -->
-<!-- - Where models struggle most -->
-<!-- - Trends over time as we iterate -->
-
-## What We Learned
-
-<!-- TODO: Key takeaways from running the benchmark -->
-<!-- - Surprising strengths and weaknesses -->
-<!-- - How benchmark results influenced product decisions -->
-<!-- - Common failure modes -->
-
-## What's Next
-
-<!-- TODO: Future directions -->
-<!-- - Expanding the benchmark (more tasks, more complexity) -->
-<!-- - Community contributions / open-sourcing -->
-<!-- - Using the benchmark to guide copilot improvements -->
