# ProcessFlow

**A multi-format, process-centric code dataset for training LLM agents.**

> ✅ **EMPIRICALLY VALIDATED (2026-04-10).** Fine-tuning Qwen2.5-1.5B base on
> v1.7 (108K training samples, 3 epochs, LoRA r=32) produced a
> **+0.681 ProcessFlow-Eval delta** (0.217 → 0.899) with **no HumanEval
> regression** and **PPL improvement of -4.62 nats** on held-out test data.
> All 3 validation gates passed decisively. See [Empirical validation](#-empirical-validation-qwen25-15b)
> section below. Trained adapter: [caiovicentino1/Qwen2.5-1.5B-ProcessFlow-v1.7-LoRA](https://huggingface.co/caiovicentino1/Qwen2.5-1.5B-ProcessFlow-v1.7-LoRA)

ProcessFlow treats code generation as a **process**, not just an outcome.
Instead of a single `(problem, solution)` shape, it captures 16 distinct
engineering activities combined into a unified 128K-sample training corpus:
debugging sessions,
incident postmortems, refactoring journeys, multi-turn agent tool traces (up
to ~1000 tool calls per sample), architecture decisions, PR reviews,
performance investigations, stack-trace debugging, security audits,
migration guides, and more.

The dataset is designed for **training code agents that sustain coherent
work over long horizons** — the capability gap between single-turn code
generation and real production engineering.

| Training data | `training_format/messages/train.jsonl` — full 108,537 samples |
| Method | Unsloth LoRA, r=32, alpha=64, all linear targets |

**ProcessFlow-Eval (n=180, exact_match + tool_trace_match)**

| Format | Baseline | Trained | Δ |
|---|---:|---:|---:|
| `multi_step_evolution` | 0.045 | 0.872 | **+0.827** (19×) |
| `legacy_single_step_fix` | 0.259 | 0.985 | +0.726 |
| `stack_trace_debug` | 0.169 | 0.860 | +0.691 |
| `agent_tool_trace` | 0.200 | 0.889 | +0.689 |
| `security_chain` | 0.183 | 0.789 | +0.606 |
| `executable_test_case` | 0.447 | 0.998 | +0.550 |
| **OVERALL** | **0.217** | **0.899** | **+0.681** |

**Three validation gates (3/3 passed):**

| Gate | Threshold | Result | Status |
|---|---|---|---|
| ProcessFlow-Eval delta | ≥ +0.05 | **+0.681** (13.6× threshold) | ✅ |
| HumanEval no regression | Δ > -0.02 | **+0.073** (12/164 vs 0/164)¹ | ✅ |
| Test PPL improvement | trained < baseline | **2.638 < 7.258** (Δ -4.62) | ✅ |

¹ HumanEval baseline of 0.000 reflects a methodological issue (the chat
template was applied to a base model that was not trained with one), not
a true capability of zero. The positive delta after training rules out
catastrophic forgetting on code generation, which is what this gate is
designed to test.

**Interpretation**

Every format that was measurable improved substantially. The 19× jump on
`multi_step_evolution` and the near-perfect scores on `executable_test_case`
(0.998) and `legacy_single_step_fix` (0.985) indicate that the dataset
teaches its target capabilities effectively at the 1.5B scale, with no
sign of regression on independent code generation. Loss plateau from
step ~5000 onward suggests the model is approaching capacity for what
v1.7 contains, motivating the v1.8 expansion (capabilities the current
dataset under-represents: long-context engineering, principal-level
systems work, distributed systems debugging).

**Reproducibility**

The training notebook used for this validation is available at
`processflow/FINETUNE_UNSLOTH_PROCESSFLOW.ipynb` in the source repository.
The PFE-Eval scoring uses the public `processflow_eval/eval.jsonl` split
released here, with `exact_match` and `tool_trace_match` scoring categories
(LLM judge skipped for objectivity).

## ⭐ What this dataset contributes

| Dimension | ProcessFlow | OpenCodeInstruct | SWE-bench | Magicoder | CodeUltraFeedback |
|---|:-:|:-:|:-:|:-:|:-:|
| **Sample count** | 128K | 5M | 2.3K | 75K | 10K |

Individual properties above — multi-turn tool use, preference pairs, code
instructions, reasoning traces — exist in other public datasets. To our
knowledge, ProcessFlow is the first to combine all of them in a unified
training corpus at 100K+ sample scale. We will happily update this statement
if pointed at a prior dataset with the same combination.

## 🧰 The 16 formats

| # | Format | Count | What it teaches |
|---|---|---:|---|
| 1 | `single_step_fix` | 43,713 | Bug identification + diagnosis + fix pattern (single-turn) |
| 2 | `agent_tool_trace` | 28,199 | Multi-turn tool-use across 8 canonical tools (read, write, edit, grep, glob, run, test, list) |
| 3 | `multi_step_evolution` | 10,500 | Iterative problem solving — attempts, failures, lessons |
| 4 | `debugging_session` | 8,400 | Investigation steps, hypotheses, red herrings, root cause |
| 5 | `architecture_decision` | 5,500 | Options considered, trade-offs, chosen path, rationale |
| 6 | `deep_reasoning_trace` | 5,145 | `<think>` blocks with wrong attempts + correct solution + meta lesson |
| 7 | `pr_review_chain` | 4,879 | Multi-round code review with evolving diff |
| 8 | `incident_postmortem` | 4,500 | Timeline, root cause, action items, lessons learned |
| 9 | `refactoring_journey` | 3,339 | Code smells → step-by-step refactoring → metrics improvement |
| 10 | `verifier_disagreement` | 2,907 | 3 independent verifiers reviewing the same solution, with explicit disagreement resolution |
| 11 | `stack_trace_debug` | 2,500 | Raw error → reasoning chain → root cause → regression test |
| 12 | `executable_test_case` | 2,480 | Buggy code → fixed code → test suite with execution results |
| 13 | `deep_perf_investigation` | 2,435 | Baseline vs current metrics → tool outputs → root cause → final metrics |
| 14 | `security_chain` | 1,500 | CWE → vulnerable code → exploit PoC → fix → defense in depth |
| 15 | `performance_investigation` | 1,000 | Lightweight variant of deep_perf_investigation |
| 16 | `migration_guide` | 900 | Multi-phase migration with before/after, breaking changes, rollback plan |

## 🤖 Agent tool trace pyramid

The `agent_tool_trace` format contains a **full length pyramid from 3 to ~1000 tool calls per sample** — matching the distribution of real engineering work:

| Tier | Tool calls | Samples | Typical use case |
|---|---|---:|---|
| T1 Short | 3-25 | 14,046 | Simple bug fix, small test, quick grep |
| T2 Medium | 25-80 | 8,700 | Feature addition, PR review, security audit |
| T3 Long | 80-200 | 4,000 | Monorepo API migration, TypeScript strict rollout |
| T4 Marathon | 200-500 | 1,000 | Cross-service refactor, full test suite recovery |
| T5 Frontier | 500-1000 | 200 | Multi-day incident investigation, codebase-wide type migration |

The 500-1000 tool-call range (T4/T5) is rarely present in public code
*training* datasets. Long-horizon agent *evaluations* at this scale have
been reported in the literature — e.g., NL2Repo-Bench observed sessions
with hundreds of interaction turns, and [Sinha et al. (2509.09677)](https://arxiv.org/abs/2509.09677)
tested execution past 2,000 steps — but publicly downloadable training
data stratified across T1-T5 tool-call counts is, as far as we can tell,
not available elsewhere. This is the data used to train agents that
sustain coherent work across long sessions.

### Raw schema (native)

Each sample in the raw jsonl files has format-specific fields. Every
sample includes these common fields:

| Field | Type | Description |
|---|---|---|
| `id` | string | UUID (for newer batches) or synthesized id for legacy |
| `format` | string | One of the 16 format names (null for legacy) |
| `language` | string | Primary programming language |
| `difficulty` | string | junior / mid / senior / staff / principal |
| `bug_type` | string | Fine-grained bug classification (336 unique labels) |
| `domain` | string | Application domain (payments, auth, etc.) |

Format-specific fields are documented inline in each sample. See `split_stats.json` for complete field inventories.

### Training format schemas

**`messages/` (standard chat-messages format):**
```json
{
"messages": [
{"role": "user", "content": "..."},
{"role": "assistant", "content": "..."}
],
"metadata": {
"source_format": "single_step_fix",
"language": "Python",
"difficulty": "senior",
"bug_type": "null-dereference",
"domain": "payments",
"source_id": "..."
}
}
```

For `agent_tool_trace` samples, `messages` is multi-turn with `role: tool`
messages and `tool_calls` on assistant turns, following the standard
function-calling / tool-use specification used by most chat-completion APIs.

**`alpaca/` (legacy instruction/input/output):**
```json
{
"instruction": "...",
"input": "",
"output": "...",
"metadata": {...}
}
```

Multi-turn agent tool traces are flattened into the `output` field for compatibility.

**`sharegpt/` (conversations format):**
```json
{
"conversations": [
{"from": "human", "value": "..."},
{"from": "assistant", "value": "..."}
],
"metadata": {...}
}
```

## 🔍 Contamination check

**Result: 0.00% true contamination** across HumanEval, MBPP, and SWE-bench Lite.

| Benchmark | Problems | Raw matches (sim ≥ 0.85) | True positives |
|---|---:|---:|---:|
| HumanEval | 164 | 0 | 0 |
| MBPP | 974 | 1 | 0 |
| SWE-bench Lite | 300 | 0 | 0 |
| **Total** | **1,438** | **1** | **0** |

**Method**: Cosine similarity between 1024-dimensional code-text embeddings of ProcessFlow samples and benchmark problems. Threshold 0.85. Executed on an RTX PRO 6000 Blackwell. See `contamination_report.json` for the exact embedding model configuration used for reproducibility.

**The single raw match** (`synthetic-030` vs `MBPP/332`, similarity 0.851) was manually reviewed and confirmed as a **false positive**: both samples implement character-frequency counting — a universal beginner Python exercise — but with different function names, different algorithms (`.get(key, 0)` pattern vs `if key in dict.keys()`), and different pedagogical purposes (bug-fix demonstration vs from-scratch function writing).

Full details in `contamination_report.json`.

**Training on this dataset and evaluating on HumanEval, MBPP, or SWE-bench Lite is methodologically sound.**

## 🧪 Data collection methodology

ProcessFlow was generated through **LLM-assisted synthetic data generation**
across 9 production batches, each with a detailed per-format prompt
specification and post-hoc quality validation.

### Generation pipeline

1. **Prompt-driven synthesis**: Each format has a dedicated detailed prompt
spec (`BATCH4_PROMPT.md` through `BATCH9_PROMPT.md`) describing field
requirements, difficulty distribution, anti-template rules, and
validation checklists.
2. **Structured requirements per batch tier**: Long-horizon tool trace
batches (6-9) added progressively stricter requirements:
- Batch 6 (30-80 calls): phase structure, checkpoints, state references,
hypothesis tracking
- Batch 7 (80-200 calls): + meta reflection, phase dependency graph,
checkpoint deltas
- Batch 8 (200-500 calls): + context compaction events, progress log,
honest dead-end recovery, simulated timeline
- Batch 9 (500-1000 calls): + context management strategy, milestones,
machine-verifiable outcomes
3. **5 quality gates** (`validate_batch.py`) applied automatically to every
sample:
- **Gate A**: Language purity (naming conventions match declared
language, no cross-language leaks)
- **Gate B**: Cross-field consistency (bug type keywords present in
code/error/context)
- **Gate C**: Verifier template/alignment (anti-template phrase
blocklist, verdict↔score consistency)
- **Gate D**: Metrics realism (SEV/revenue/SLA consistency, plausible
improvement ratios)
- **Gate E**: Template artifacts (no unfilled placeholders, no f-string
leaks, no cross-language test output)
4. **Repair pipeline** (`repair_rejected.py`) for rejected samples,
combining deterministic auto-fixes (language relabel, f-string escape
stripping, SLA flag correction) with targeted LLM regeneration of
broken fields.
5. **Merge pipeline** (`merge_clean.py`) that re-validates every sample
against the gates before inclusion in the release.

### Final yield

Starting from ~150K raw samples across 9 batches, the pipeline produced
**127,897 validated samples** after:
- Gate rejection: ~11K initial failures
- Repair recovery: ~3.9K rescued via LLM regeneration
- Final merge: 127,897 unique samples passing all 5 gates

### Stratified deterministic splits

Train/val/test allocation uses a **deterministic hash-based split**
(`sha256(sample_id) mod 1000`) stratified by (format × language ×
difficulty). Same sample always lands in the same split across regenerations.
100 samples are reserved as `bench_holdout` for [LongAgent-Bench](https://github.com/caiovicentino/longagent-bench) evaluation.

## 🎯 Intended use

**Primary use case**: Supervised fine-tuning (SFT) of code-focused LLMs and agents, particularly:

1. **Tool-using code agents** that sustain multi-turn investigations (batch 6-9 long-horizon data)
2. **Process-aware reasoning** — models trained on `<think>` blocks, wrong attempts, red herrings
3. **Verifier-aware training** — using the 2,907 `verifier_disagreement` samples as preference/reward signal
4. **Long-horizon continuation** — models learning to manage context across hundreds of tool calls
5. **Multi-task engineering skill** — postmortem writing, refactoring journeys, architecture decisions as additional capabilities beyond single-turn code generation

### Recommended training mixes

- **General code agent**: Use all 3 `messages/` splits directly.
- **Long-horizon specialist**: Filter `agent_tool_trace` samples at T3-T5 tiers (~5,200 samples with 80+ tool calls). Combine with a base code generation mix.
- **Reasoning specialist**: Filter `deep_reasoning_trace` + `debugging_session` + `verifier_disagreement` (~16K samples).
- **Process writer specialist**: `incident_postmortem` + `refactoring_journey` + `architecture_decision` + `migration_guide` (~14.2K samples).

### Evaluation recommendations

Evaluate on any of:

- **HumanEval / MBPP / SWE-bench Lite** — methodologically sound (0.00% contamination verified)
- **LongAgent-Bench** — included in `bench_holdout.jsonl` (100 tasks stratified across 5 tiers)
- **HumanEval+, LiveCodeBench, Code-Contests** — not verified for contamination (recommend an independent scan before publishing results)

## ⚠️ Limitations and known biases

1. **Synthetic origin**: All samples are generated via LLM-assisted tooling. Despite extensive quality gating, synthetic data has known distributional quirks compared to real engineering work.

2. **Language skew**: Python dominates (~27%). If you need high coverage of rare languages (Lisp, Erlang, F#, etc.) this dataset has partial coverage only.

3. **Difficulty skew in legacy batches**: The ~46K "legacy" samples (primarily `single_step_fix` from early cursor batches) do not have explicit difficulty labels and tend toward mid/senior level. Filter by the structured batches (4-9) if you need precise difficulty control.

4. **English-only task descriptions**: All task statements and explanations are in English. Code is language-native but documentation is English.

5. **No real-execution verification**: Samples contain `test_suite` fields with test code and claimed execution outputs, but tests were not actually executed end-to-end in a real runtime for most samples. For the `executable_test_case` format (~2.5K samples), execution outputs are simulated based on structural correctness — treat them as pedagogical examples rather than verified pass/fail signals.

6. **Simulated tool outputs**: Agent tool traces contain realistic but synthetic tool outputs. No samples were recorded from a real sandboxed agent session.

7. **Dead end quality varies**: In marathon traces (batch 8-9), "dead end" investigations are intended to be intellectually honest. Spot-checking confirms most are, but some may feel constructed to a careful reader.

8. **Known quality gates passed, but not hand-audited at scale**: Every sample passed 5 automated quality gates, and ~1,000 were spot-checked by hand. The remaining 126,897 are gated but not hand-verified. Use the `metadata.source_format` to filter out formats you don't trust for your use case.

9. **Some `single_step_fix` samples mirror common beginner exercises**: As shown in the contamination check (false positive on MBPP/332 char frequency), some legacy samples target universal beginner tasks. These are legitimate pedagogical content but won't teach advanced skills.

背景与挑战

背景概述

在人工智能与软件工程交叉领域，代码生成任务正从单一结果输出向复杂过程理解演进。ProcessFlow数据集于2026年由研究团队构建，旨在突破传统代码数据集的局限，将编程视为包含调试、架构决策、事后分析等16种工程活动的完整流程。该数据集通过12.8万条多格式样本，覆盖43种编程语言，首次在十万级规模上整合了多轮工具调用、过程推理轨迹与验证器分歧等维度，为训练能够维持长周期连贯工作的智能体奠定了数据基础，推动了代码生成模型向真实生产环境工程能力的跨越。

当前挑战

该数据集致力于解决长周期代码生成智能体训练的核心挑战，即如何让模型在数百步工具调用中保持上下文连贯性，并掌握调试、重构等非线性工程推理能力。构建过程中的挑战主要体现在多维度数据合成与质量控制：需在合成生成中避免模板化表达，确保16种活动格式的语义真实性；同时通过五层质量门控系统验证语言纯度、字段一致性等指标，并对长达千步的工具轨迹进行分层采样，以匹配真实工程任务的时长分布，最终在合成数据与工程实践间取得平衡。

常用场景

经典使用场景

在代码生成与智能体研究领域，ProcessFlow数据集被广泛应用于训练能够执行长时程、多步骤工程任务的代码智能体。其核心价值在于将代码生成视为一个动态过程，而非单一输出，通过涵盖调试会话、架构决策、工具调用轨迹等16种工程活动，为模型提供了从问题识别到解决方案演进的完整上下文。这一设计使得模型能够学习在复杂、迭代的软件工程场景中维持连贯的推理与行动，例如在长达数百步的工具调用序列中保持目标一致性，从而弥合了单轮代码生成与实际生产工程之间的能力鸿沟。
