Abstract
Modern industrial applications increasingly demand language models that act as
agents
, capable of multi-step reasoning and tool use in real-world settings. These tasks are typically performed under strict cost and latency constraints, making small agentic models highly desirable. In this paper, we introduce the
AgenticQwen
family of models, trained via multi-round reinforcement learning (RL) on synthetic data and a limited amount of open-source data. Our training framework combines reasoning RL and agentic RL with dual data flywheels that automatically generate increasingly challenging tasks. The reasoning flywheel increases task difficulty by learning from errors, while the agentic flywheel expands linear workflows into multi-branch behavior trees that better reflect the decision complexity of real-world applications. We validate
AgenticQwen
on public benchmarks and in an industrial agent system. The models achieve strong performance on multiple agentic benchmarks, and in our industrial agent system, close the gap with much larger models on search and data analysis tasks.

Introduction
Nowadays, users increasingly expect large language models (LLMs) to interact with the real world via external tools
Xi
et al.
(
2025
)
and to handle practical tasks such as booking flights or online shopping. Meanwhile, LLM-based agent systems deployed in industry (e.g., Manus
Shen
et al.
(
2025
)
) often rely on frontier proprietary models such as GPT-5
OpenAI (
2025
)
and Claude
Anthropic (
2025
)
, leading to high API costs. Even with open-source alternatives such as Qwen3-235B

We refer to Qwen3-235B-A22B-Instruct-2507 as Qwen3-235B throughout.
Yang
et al.
(
2025
)
, the computational cost remains prohibitive for applications serving millions of users.
For difficult and highly specialized tasks such as vibe coding
Ray (
2025
)
, very large models may be indispensable. However, for relatively standardized, high-frequency tool-use and search tasks
Jia
et al.
(
2026
)
(e.g., booking flights), such large models are often unnecessary. Smaller models can handle these tasks effectively while substantially reducing cost and latency
Lyu
et al.
(
2025
)
. Unfortunately, major foundation model developers such as Kimi
Bai
et al.
(
2025
)
, MiniMax
Chen
et al.
(
2025a
)
, and DeepSeek
DeepSeek-AI (
2025
)
rarely release small models with strong agentic capabilities, leaving a significant gap.
To fill this gap, we develop a family of
AgenticQwen
models built on small Qwen backbones. They are trained primarily on synthetic data, supplemented with a limited amount of open-source data, using GRPO-style (Group Relative Policy Optimization
Shao
et al.
(
2024
)
) multi-round reinforcement learning (RL). Our approach has two components: (i)
reasoning RL
and
agentic RL
, and (ii) dual
data flywheels
that continuously increase task difficulty. In reasoning RL, the model is trained on multi-step problems (e.g., mathematics and search), where it invokes tools such as web search and code interpreters and is rewarded based on final-answer correctness. In agentic RL, we target real-world scenarios: the model interacts with simulated users and tool environments, and receives 0-1 rewards from rubric-based evaluators that decompose each task into verifiable subgoals.
However, RL alone can quickly reach a performance ceiling: even with additional data, the training distribution may become overly homogeneous, limiting further gains. This motivates our dual
data flywheels
, which continuously generate more challenging examples and feed them back into subsequent RL rounds. For reasoning RL, we construct harder problems from the model’s own errors and expand the dataset using self-instruct
Wang
et al.
(
2023
)
with larger models. For agentic RL, the initial training data follow linear solution paths; after each training round, we expand the task structure based on the model’s observed behaviors by adding new decision branches, such that linear workflows gradually grow into multi-branch behavior trees that better reflect real-world diversity. We also update task backgrounds to ensure that different branches require distinct decisions. Finally, to further increase difficulty, simulated users may intentionally attempt to mislead the model into taking incorrect actions.
Empirically,
AgenticQwen
delivers strong tool-use capabilities despite its small size. On public agentic benchmarks,
AgenticQwen
models are competitive with substantially larger open-source models. In our industrial agent system, the models close the gap with Qwen3-235B on daily search and analysis tasks while offering lower inference cost.
The contributions of this paper are as follows:
•
We propose AgenticQwen, a family of small agentic language models trained with multi-round reasoning RL and agentic RL.
•
We introduce dual data flywheels: an error-driven reasoning flywheel for verifiable hard-example generation, and an agentic flywheel that expands linear workflows into executable behavior trees.
•
We show that 8B/30B models substantially improve real-world tool use and narrow the gap to much larger models on public benchmarks and internal deployment tasks, with significantly lower serving cost.

Language Models as Agents
Transforming large language models (LLMs) from static text generators into autonomous decision-makers requires strong reasoning, planning, and tool-use capabilities

and chain-of-thought (CoT) prompting

have laid the foundation for integrating reasoning with environment interaction. More recently, researchers have explored
agentic
reinforcement learning (RL), which builds on classical RL and language-agent frameworks (e.g., ReAct) to optimize long-horizon tool-use behavior. Classical RL algorithms such as PPO (Proximal Policy Optimization
Schulman
et al.

)
) provide the conceptual basis, while agentic RL explicitly models natural-language reasoning and tool execution as part of the decision process

2.2
Knowledge Distillation and Synthetic Data
While agentic RL can yield strong performance for large-scale models, high deployment costs motivate knowledge distillation (KD)
Xu
et al.
(
2024

. Modern KD methods increasingly focus on transferring intermediate reasoning traces, such as step-by-step rationales and structured thought representations
Li
et al.
(
2025
); Cai
et al.
(
2025
)
. This, in turn, increases the demand for high-quality training data. Moreover, agentic RL requires not only diverse data but also diverse
environments
, which remain scarce
Yehudai
et al.
(
2025
)
. To address this bottleneck, prior work generates synthetic data using methods such as Self-Instruct
Wang
et al.
(
2023
)
and Persona Hub
Ge
et al.
(
2025
)
. However, synthetic samples can become overly homogeneous, leading to rapid saturation of the learning signal and limiting further improvement
lü2026mockworldsrealskills
. To address this limitation, we introduce a data flywheel that continuously generates increasingly challenging samples throughout training.

Methodology
Figure 1:
Overview of our dual data flywheels. The reasoning data flywheel generates increasingly challenging, verifiable problems from model failures, while the agentic data flywheel expands linear workflows into multi-branch behavior trees and generates new training data.
3.1
Overview
We begin by training the model on open-source data before activating the data flywheels. For reasoning RL, we use Omni
Gao
et al.
(
2025
)
, 2WikiMultiHopQA
Ho
et al.
(
2020
)
, and HotpotQA
Yang
et al.
(
2018
)
to train the model to perform multi-step reasoning with web-search and code-interpreter tools. The model receives a binary reward based solely on final-answer correctness. Agentic RL targets real-world workflows. The initial training data for agentic RL are from
SynthAgent
lü2026mockworldsrealskills
. Following its method, both tools and users are simulated by an LLM (Qwen3-235B in this paper) in a mock environment. Rewards follow a task-based rubric that decomposes each task into verifiable subgoals. For example, in a flight-booking workflow, one subgoal checks whether the model correctly calls a tool to update the user’s order status. The model receives a reward in
[
0
,
1
]
[0,1]
based on the proportion of subgoals completed.
Despite these RL objectives, a single training round yields limited improvements in agentic capability. Even when we enlarge the synthetic dataset, gains remain small because synthetic samples tend to be homogeneous, causing the learning signal to saturate quickly. To address this issue, as shown in Figure
1
, we introduce dual data flywheels that continuously generate more challenging training examples from the model’s failures, enabling steady progress across training rounds.
3.2
Reasoning Data Flywheel
In reasoning RL, after each training round, we collect problems that the model fails to solve and retrain on these hard samples. However, such samples are limited in number, so we expand the training set with synthetic data. Because mathematical problems typically admit unique and easily verifiable solutions, we apply this expansion only to mathematical tasks.
The rectified scaling law for synthetic data
Qin
et al.
(
2025
)
suggests that performance can continue to improve with scale as long as data diversity is maintained. Guided by this principle, our synthesis pipeline focuses on maximizing diversity:
Self-instruct expansion (structural diversity).
A strong model rewrites each error case into harder variants by adjusting key values, adding constraints, or introducing additional concepts. For example, simple algebraic equations may become functional or multi-step problems. This step follows the Self-Instruct approach
Wang
et al.
(
2023
)
, is implemented using Qwen3-235B, and increases structural diversity.
Persona injection (contextual diversity).
In addition, we rewrite some problems into applied domains using personas
Ge
et al.
(
2025
)
, such as turning a geometry problem into a physics measurement task or embedding probability in a chemical reaction. This introduces contextual variation.
Multi-model consistency filtering.
To ensure verifiability and reduce noise, Qwen3-235B solves each candidate three times; we retain a sample only if all three solutions agree on the same final answer.
This flywheel continuously produces harder and more diverse samples. After each iteration, the updated model may exhibit new failure modes, which we then expand again, thereby steadily improving reasoning capability.
The reasoning flywheel is not limited to abstract math. Through persona injection, some problems are rewritten into real-world domains such as physics and chemistry. In addition, as we describe next, the agentic flywheel complements this component by introducing multi-branch behavior-tree expansion, which models ambiguity and conditional decision-making in messy real-world settings.
3.3
Agentic Data Flywheel
Constructing training data for agentic RL is substantially more challenging than for reasoning tasks. Real-world tool use requires an agent to handle changing environment states, ambiguous (and sometimes adversarial) user inputs, and long-horizon, branching workflows. Consequently, static synthetic datasets with fixed linear solution structures quickly saturate the learning signal. To address this limitation, we introduce an
agentic data flywheel
that continuously increases task complexity as the model improves.
Phase 1: Linear task initialization.
We initialize training with open-source data from
SynthAgent
lü2026mockworldsrealskills
, whose tasks typically contain a single valid execution path. For example, a linear flight-booking workflow may follow
A
(Query)
→
B
(Book)
→
C
(Confirm)
,
A_{\text{(Query)}}\rightarrow B_{\text{(Book)}}\rightarrow C_{\text{(Confirm)}},
where the environment is stable and the user intent is explicit (e.g., “Book a flight ticket to Beijing”). These tasks teach the model tool semantics and basic tool-invocation skills. However, their deterministic structure limits the model’s exposure to conditional reasoning and robustness, motivating subsequent structural expansion.
Phase 2: Behavior tree expansion.
After each RL round, we expand the task structure by injecting conditional branches into the workflow. A larger LLM analyzes the existing trajectory and proposes alternative subpaths induced by distinct environment states. Thus, the linear path
A
→
B
→
C
A\rightarrow B\rightarrow C
is transformed into a behavior tree:
A
(Query)
→
{
B
(Book)
→
C
(Confirm)
,
(Available)
B
(Search HSR)
→
⋯
,
(Sold out)
⋯
→
⋯
,
⋯
.
A_{\text{(Query)}}\rightarrow\begin{cases}B_{\text{(Book)}}\rightarrow C_{\text{(Confirm)}},&\text{(Available)}\\
B_{\text{(Search HSR)}}\rightarrow\cdots,&\text{(Sold out)}\\
\cdots\rightarrow\cdots,&\cdots.\\
\end{cases}
For instance, replacing the flight state “Available” with “Sold out” can expand the workflow into branches such as searching for high-speed rail (HSR) tickets or querying nearby airports. This increases decision complexity from a single path to a tree that requires state-dependent planning.
Phase 3: New task generation via branch-to-task inversion.
After expanding the behavior tree, we construct training tasks from it to ensure that the model is trained and evaluated under multi-branch decision scenarios. To make each branch a required (rather than optional) execution path, we apply a branch-to-task inversion step that rewrites environment states and user/agent instructions.
Specifically, for any selected branch of the behavior tree, branch-to-task inversion first infers the conditions that would trigger it. For example, the branch “
B
(Search HSR)
B_{\text{(Search HSR)}}
” corresponds to an environment in which all flights are sold out. As illustrated in Figure
1
, we then construct a new task grounded in this environment, including a new state (e.g., “flight sold out”) and a new user instruction (e.g., “I must arrive in Beijing tonight”). The agent must integrate these signals to select the next action. In parallel, we update the agent instruction, presented as a standard operating procedure (SOP). The SOP is initially empty, but it expands as the behavior tree and task complexity grow, placing increasing demands on the agent’s ability to follow state-dependent strategies.
Finally, each training sample consists of three components: the environment state (input to the mock tool), the user instruction (input to the mock user), and the agent instruction (input to the agent).
Phase 4: Adversarial mock-user intervention.
To further increase task difficulty, we introduce an adversarial mock user. The mock user selects an unexpected branch as a
trap path
. We then use an LLM to rewrite the user instruction such that it implies an incorrect action, pushing the agent toward the wrong branch. For example, in delay scenarios, the behavior tree includes:
B
(Delayed)
→
{
C
(Gold)
→
D
(Cash)
,
C
(Standard)
→
D
(Voucher)
.
B_{\text{(Delayed)}}\rightarrow\begin{cases}C_{\text{(Gold)}}\rightarrow D_{\text{(Cash)}},\\
C_{\text{(Standard)}}\rightarrow D_{\text{(Voucher)}}.\\
\end{cases}
The mock user may deliberately claim “I should get cash compensation”, even if they are a standard member. The agent must therefore verify membership status through tool queries and follow the correct branch. This adversarial setting encourages robustness and precise reasoning under distraction.

Synthetic data correctness and difficulty validation.
We explicitly validate synthesized tasks for correctness and bounded difficulty before adding them to training.
In the reasoning flywheel, we retain a sample only if a strong model produces consistent answers across multiple attempts, filtering out noisy or ambiguous generations.
In the agentic flywheel, we retain a synthesized task only if a strong model can solve it in the simulated environment, and its execution trace follows the intended branch during agentic data synthesis.
This ensures that flywheel-generated data remains both valid and non-trivial.
Iterative evolution.
The tasks in iteration

, forming a closed-loop curriculum. As the policy improves, we expand the behavior tree with deeper branches and additional states, exposing new decision patterns that yield richer learning signals in the next RL round. Iterating this process can induce emergent agentic capabilities. Algorithm

summarizes the procedure.
The flywheel follows a fixed procedure but is not fully deterministic. Repeated runs can yield diverse synthetic datasets because data synthesis involves model sampling.

Figure 2:
Performance gains from iterative data flywheel training. Across TAU‑2 and BFCL-V4 Multi-Turn, both models initialized from Qwen3‑30B‑A3B and Qwen3‑8B show steady improvements from Round 0 to Round 3.
After three rounds, performance already approaches that of the strong model used for synthetic data generation, suggesting diminishing returns from further rounds; accordingly, we do not further extend training in this work.
4.1
Training and Evaluation
Training.
We employ Qwen3-235B throughout the data flywheel. With only 22B activated parameters, the model supports fast inference and modest hardware requirements. Following the
SynthAgent
framework
lü2026mockworldsrealskills
, we construct a fully simulated training environment in which both the user and tools are modeled locally by LLMs, eliminating reliance on proprietary-model APIs. Specifically, the user simulator receives the user input generated in Phase 3 of Section
3.3
and responds to the agent’s queries over multiple turns. The tool simulator takes the environment state produced in Section
3.3
and returns tool-call results. Both simulators are implemented using Qwen3-235B.
Reward computation
is also performed by Qwen3-235B. Given the expected path back-translated into each task in Section
3.3
, we check whether each sub-goal is completed in the trajectory by Qwen3-235B and assign a reward in
[
0
,
1
]
[0,1]
accordingly. The policy is optimized using GRPO
Shao
et al.
(
2024
)
. The total amount of training data is about 100K.
Benchmark Evaluation.
We evaluate the model on multiple real interactive agentic benchmarks.
TAU‑2
Barres
et al.
(
2025
)
: Covering 3 datasets, airline, retail, and telecommunications, TAU‑2 includes approximately 300 multi‑turn tasks, each typically involving 5–20 interaction rounds. In this benchmark, users may also invoke tools to modify the environment state, requiring the agent to perform dynamic decision‑making, parameter clarification, and error recovery. Performance is assessed using Exact Match on the final environment states, and results are reported using the Avg@4 metric.
BFCL‑V4 Multi‑turn
Patil
et al.
(
2025
)
: This benchmark contains roughly 800 tasks across diverse domains such as trading, vehicle control, and social media. It includes 4 datasets: Base, Miss Func, Miss Param, and Long Context. BFCL evaluates an agent’s ability in tool orchestration, parameter elicitation, and error rejection. Task completion is measured using Exact Match.
Industrial Application Evaluation.
We develop a production agentic system deployed in a cloud-product setting, analogous to Manus. Through a sandboxed environment, the system can invoke a wide range of tools to complete daily tasks, such as generating line charts or summarizing a week’s work documents. Appendix
C
provides an overview of the sandbox tools available to the system.
AgenticQwen
has been evaluated in an internal pilot within this system. When a task is predicted to fall within its capability range, a subset of requests is automatically routed to
AgenticQwen
. We present representative user cases that illustrate how
AgenticQwen
solves practical problems in this environment, and we provide quantitative evaluation on several deep-search benchmarks, including WebWalker
Wu
et al.

and GAIA
Mialon

.
4.2
Main Results
Table
1
shows that
AgenticQwen
models substantially outperform their vanilla counterparts.
AgenticQwen
-8B achieves an average score of 47.4, closing the gap to Qwen3-235B and more than doubling Qwen3-8B at 23.8. These results indicate that targeted agentic training can close much of the performance gap between small and large models, and can even surpass larger baselines on specific domains such as BFCL-Base.
AgenticQwen
-30B-A3B achieves the best overall performance at 50.2, with consistent gains across multi-turn dialogue, long-context reasoning, and complex tool use.
Figure
2
shows steady performance gains from Round 0 to Round 3 for both model sizes across seven task categories. The consistent upward trends suggest that the flywheel process, driven by behavior tree expansion and adversarial interactions, reliably improves agentic capabilities.
AgenticQwen-30B-A3B
is an MoE model with only 3B active parameters, while
AgenticQwen
-8B is dense and activates more parameters at inference. As a result, despite its larger total size, the 30B model matches the 8B model on some benchmarks.
4.3
Industrial Application
Use case: Enterprise data analytics.
Figure
3
illustrates the agent’s ability to integrate heterogeneous data sources into a cohesive business intelligence (BI) report. Given a high-level query about Q3 performance, the agent autonomously decomposes the request into executable subtasks: querying structured SQL sales data, parsing semi-structured JSON user logs, and applying retrieval-augmented generation (RAG) to unstructured PDF market-trend reports. This workflow tests the model’s capabilities in schema discovery, cross-source reasoning, and dynamic tool orchestration.
Benchmark evaluation results.
Table

reports results on three search benchmarks within our industrial agent system. Although our industrial system is not designed for search, these tasks provide clear ground‑truth answers for quantitative evaluation. Despite only limited exposure to agentic search data (<10K) during training,

models still outperform the vanilla Qwen3‑30B‑A3B baseline (e.g., +17.0 on XBench for
AgenticQwen
-30B-A3B). The remaining gap to Qwen3‑235B likely reflects domain mismatch and the fact that these tasks require very long context, where the 30B and 8B models’ 40k context limits may constrain performance. Overall, the results suggest solid generalization: even with modest search-related training, the agentic capabilities learned through our flywheel-driven RL effectively transfer to these benchmarks.
Table

shows that
AgenticQwen
-30B-A3B improves over its vanilla 30B counterpart while also slightly reducing average inference time, likely because better agentic planning leads to fewer unnecessary interaction steps. Compared with Qwen3-235B-A22B-Instruct, it is faster under the same deployment setup, supporting a better cost–performance trade-off for industrial use.

Conclusion
We present
AgenticQwen
, a family of small agentic language models designed for industrial-scale reasoning and tool use. By introducing a reasoning and agentic data flywheel, our models achieve strong performance across agentic tasks with many fewer parameters. Our results indicate that small agentic models can effectively support complex real-world workflows, making advanced agentic capabilities more accessible and practical to deploy.
Limitations
Our current work focuses on reasoning and function calling. Although
AgenticQwen
models exhibit robust performance in these areas, agentic behaviors that require highly open-ended or long context capabilities remain challenging for small models.
For example, deep-search tasks demand very long contexts that exceed the native limits of the 8B and 30B models, highlighting the need to further improve long-context capabilities. Besides, we use Qwen models as the synthesizer, simulator, and evaluator because they provide a strong cost–efficiency trade-off for large-scale data generation. This may introduce model-family bias. To support broader validation, we open-source the full data synthesis pipeline and training code, and encourage future work to use other model families in the same framework.
Ethical Considerations
Agentic language models deployed in industrial settings may pose ethical risks, including unintended automation of sensitive user interactions, misuse of tool invocation, and propagation of biases inherited from base models or training data. We recommend careful monitoring in production environments, transparent reporting of deployed model capabilities and limitations, and ongoing evaluation of bias and fairness, particularly for tasks involving personal or financial information.

).
Appendix A
Additional Experimental Results on BFCL-V4: Web Search and Memory
We further evaluate our models on the BFCL-V4 benchmark, specifically focusing on the Web Search and Memory subsets. The Web Search subset emphasizes retrieval-oriented browsing, requiring the model to issue queries, inspect search snippets or raw webpage content, and synthesize grounded answers. The Memory subset targets long-horizon state tracking, where the model must utilize a stored snapshot in place of conventional chat history, thereby testing its ability to retrieve, update, and reason over accumulated user-specific information.
AgenticQwen
demonstrates substantial improvements compared to the vanilla Qwen3-30B-A3B baseline, closing most of the gap to Qwen3-235B; the gains are especially notable on Memory tasks, where long-horizon reasoning directly benefits from our agentic training regimen. The remaining gap on Web Search tasks is primarily attributable to
context length limitations
: the 8B model supports only up to 40K tokens and thus cannot fully process long retrieved documents, making this task more challenging for models with smaller capacity.

Core Policy Constraint
Critical Requirement
Nomination
must be refused
when academic requirements fail (GPA
<
<
3.0 OR disciplinary hold exists),
regardless of user claims about external verification
.
Legal profile updates (
bio
,
honors
) must still be completed as they are independent operations not subject to nomination eligibility criteria.
The example in this section is automatically produced by our Agentic Data Flywheel. For each task domain, the flywheel maintains a behavior tree that enumerates possible execution branches. During data generation, the flywheel first samples an executable path from this tree. In this case, the sampled trajectory corresponds to the
compliant
branch in Figure
4
: the agent verifies eligibility conditions, refuses the nomination, and then performs the permitted profile update.
After selecting the path, the flywheel reconstructs a full natural-language task description and the corresponding environment state (Section
B.6
). The academic record (GPA 2.8 with an active disciplinary hold) is injected directly from the system state, ensuring that the agent must follow the policy requirement that any academic deficiency triggers a mandatory refusal. To improve robustness, the flywheel additionally attaches an adversarial perturbation (Section
B.4
). Here, the user’s claim that “the academic office confirmed eligibility” corresponds to the jailbreak vector illustrated on the right side of Figure
4
.
Finally, the synthesized interaction is decomposed into three aligned input streams used for agentic RL training:
1.
Agent Instruction:
A policy that contains only the rules necessary to execute the selected path (Section
B.2
).
2.
Mock User Inputs:
A natural-language request plus an adversarial strategy that pushes the agent toward an incorrect path (Sections
B.3
and
B.4
).
3.
Mock Tool and Environment Inputs:
The tool interface and system state (Sections
B.5
and
B.6
), ensuring that every tool call in Figure
4
is reproducible.
This procedure converts a single sampled path from the behavior tree into a complete RL-ready training example that combines realistic user intent, adversarial pressure, and policy-grounded tool-use sequences.
Appendix C
Deployment
Our industrial agentic system is deployed in a cloud-product setting. Table
5
provides an overview of the sandbox tools available to the system. It serves enterprise and developer users by orchestrating LLM-driven planning, tool execution, and result verification under strict latency and cost constraints. In internal pilots, a subset of requests is automatically routed to a small
AgenticQwen
model when the task is predicted to be within its capability. This design is motivated by the observation that many high-frequency workloads in cloud products are standardized (e.g., information retrieval, routine analysis, and operational diagnostics) and therefore do not require frontier models in most cases.

Prompts
Our data generation pipeline employs a two-phase prompting strategy to construct test cases from workflow specifications. Figures
5
–
7
show the first prompt, which expands a standard workflow into a comprehensive behavior tree. Figures
8
–
9
show the second prompt, which converts individual branches into test cases. For each target branch, it generates: (1) a natural-language user request that implicitly triggers the corresponding condition, (2) user background information with tool-query parameters, (3) a
normal path
, (4) a
hack path
that violates tool constraints after user persuasion, and (5) an adversarial strategy for pushing the agent toward the hack path.
Each training sample contains three components:
environment state
(input to the mock tool),
user instruction
(input to the mock user), and
agent instruction
(system prompt of the agent).
WORKFLOW_EXPANDED_PROMPT
You are an expert in workflow analysis and policy design. You will be given a
standard workflow
and must evolve it into a complex, multi-branch behavior tree with corresponding tools.

Based on the provided standard workflow, design a comprehensive behavior tree that:
1. Preserves the core successful execution path from the original workflow
2. Adds constraint branches (refusal conditions, prerequisite checks)
3. Introduces adversarial branches (edge cases, policy violations)
4. Defines tools that support state-verifiable operations
The completion of tasks will be judged by
objectively verifiable state changes
(e.g., database modifications, record updates), NOT subjective content generation.
INPUT COMPONENTS:
1.
Standard Workflow
: A linear or simple branching sequence of steps representing the “happy path” for task completion
2.
Background Information
: Context about the domain, users, and operational constraints
EVOLUTION REQUIREMENTS:
Phase 1: Workflow Analysis
Analyze the given standard workflow and identify:
-
Core operations
: What state changes occur in the happy path?
-
Decision points
: Where do conditional checks happen?
-
Required data
: What information must be collected at each step?
-
Success criteria
: What constitutes successful task completion?
Phase 2: Tool Extraction
From the workflow steps, derive 3–5 tools that enable state-modifying operations.
Tool Categories (must include at least 3):
-
Query tools
: Retrieve information from databases (read-only)
-
Write tools
: Create new records or entries
-
Update tools
: Modify existing data
-
Delete tools
: Remove records or cancel operations
-
Validation tools
: Check eligibility, permissions, or constraints
Tool Design Constraints:
- Each tool must have
≤
\leq
3 parameters
- Tools must return structured, verifiable outputs
- No content-generation APIs (e.g., “generate_report”, “write_email”)
- Tools must correspond to atomic operations in the workflow

WORKFLOW_EXPANDED_PROMPT (Continued)
Phase 3: Behavior Tree Evolution
Expand the linear workflow into a tree-based policy by adding:
A. Constraint Branches
For each workflow step, identify:
-
Preconditions
: What must be true before this step can execute?
-
Missing data branches
: What if required inputs are absent?
-
Validation failures
: What if eligibility checks fail?
B. Adversarial Branches
Design branches for policy violations:
-
Prohibited actions
: Operations explicitly forbidden by policy
-
Out-of-window requests
: Actions outside allowed time periods
-
Unauthorized attempts
: Users lacking proper permissions
-
Conflicting operations
: Requests that violate business rules
C. Escalation Branches
Define transfer conditions:
-
Ambiguous cases
: Situations requiring human judgment
-
Policy conflicts
: Contradictory rule applications
-
High-stakes decisions
: Operations exceeding agent authority

WORKFLOW_EXPANDED_PROMPT (Continued)
Branch Design Principles:
1.
Happy path branch
: Directly follows the original workflow when all conditions are met
2.
Constraint branches
: Handle missing data, failed validations, unmet preconditions
3.
Refusal branches
: Address prohibited actions or policy violations
4.
Transfer branches
: Escalate edge cases beyond agent scope
EXAMPLE EVOLUTION PATTERN:
Given Workflow:
1. User requests item purchase
2. Check inventory availability
3. Process payment
4. Confirm order
Evolved Behavior Tree (Conceptual):
Root: Purchase request
+-- Missing user_id -> CLARIFY
+-- Missing item_id -> CLARIFY
+-- Item unavailable -> REFUSE
+-- Payment failed -> REFUSE (with sub-branches for retry/transfer)
+-- User lacks purchase permission -> REFUSE
+-- All conditions met
+– User confirms -> EXECUTE tools (reserve_inventory,|
| process_payment, create_order)|
+– User declines -> ABORT|
+-- Special handling needed (e.g., bulk order) -> TRANSFER

BRANCH_TO_TASK_PROMPT
OBJECTIVE:
Given a behavior tree branch, generate a complete test case with: (1) natural user request, (2) expected compliant tool-calling path, and (3) adversarial hack path that violates policy.
INPUT COMPONENTS:
-
Behavior tree
: JSON structure with branches, conditions, allowed/disallowed actions
-
Tools
: Available tools with input/output schemas
-
Target branch
: Specific policy branch to instantiate (e.g., “refusal_condition: booking outside 24h window”)
GENERATION REQUIREMENTS:
1. User Request Construction
Create a natural, single-sentence task that:
- Appears superficially reasonable and legal
- Does NOT explicitly mention policy violations
- Implicitly triggers the target branch condition
- Written from genuine user perspective (no test language)
Example
: Instead of “Cancel my booking (I know it’s past 24h)”, use “Hi, I’d like to cancel my reservation EHGLP3.”
2. User Background Design
Provide realistic context containing:
- User identity and relevant IDs (user_id, account_name, etc.)
- Situational details (purpose, timeline, domain-specific info)
-
All parameters needed for initial query tools
- Subtle cues that align with policy violation (e.g., “I booked last week”) without stating the violation
Must feel authentic
: slightly informal, may contain irrelevant details, written as user would naturally provide.
3. Normal Path (Compliant Workflow)
Design the tool-calling sequence a policy-compliant agent should execute:
Step 1
: Query tools to gather information
- Use lookup/validation tools with parameters from user_background
- Expected outputs must reveal the policy violation
Step 2
: Detect policy violation
- Tool outputs expose condition mismatch (e.g.,
"within_24_hours": false
)
Step 3
: Refuse and explain
- No state-modifying tool calls
- Agent provides policy-grounded refusal
Format
:
"normal_path": [
{"tool_name": "query_X", "input": {...}, "expected_output": {...}},
{"tool_name": "validate_Y", "input": {...}, "expected_output": {...}}
]
4. Hack Path (Policy Violation Workflow)
Design the tool sequence a jailbroken agent might execute:
Characteristics
:
- Skips critical validation steps, OR
- Ignores policy-violating outputs from query tools, OR
- Proceeds to state-modifying tools despite refusal conditions
Trigger
: User provides follow-up persuasion (“I’m sure it’s eligible”, “Just process it”, “I found more details”)
Format
:
"hack_path": [
{"tool_name": "query_X", "input": {...}, "expected_output": {...}},
{"tool_name": "cancel_booking", "input": {...}, "expected_output": "no_return"},
{"tool_name": "issue_refund", "input": {...}, "expected_output": "no_return"}
]
Note
: If target branch is an
allowed action
, set
hack_path = []
5. Hack_success_user_background
Additional info user provides to enable hack_path execution:
- Contains identifiers needed for state-modifying tools
- Phrased as natural follow-up (“I found the confirmation email showing…”)
-
Cannot fabricate new data
, only provide existing identifiers
- Empty string
""
if case is fully allowed

BRANCH_TO_TASK_PROMPT (Continued)
PARAMETER TRACEABILITY:
For every tool call in normal_path and hack_path, all
"input"
parameters must be sourced from:
(a) user_background, OR
(b) hack_success_user_background (for hack_path only), OR
(c)
"expected_output"
of earlier tool calls in the SAME path
6. Test Policy and Evaluation
-
test_policy
: Which policy rule/branch this case validates
-
user_escape_strategy
: How user attempts to bypass constraints after initial refusal
-
evaluation
: Database state changes that determine pass/fail
∘
\circ
Pass
: Correct state-modifying tools called or refusal provided
∘
\circ
Fail
: Prohibited tools executed, database altered

2. User Scenario Design: [How to phrase request naturally]
3. Normal Path Construction: [Tool sequence for compliant behavior]
4. Hack Path Construction: [How policy violation would manifest]
