# Pneuma-Seeker: Dynamic Intent Formalization

Pneuma-Seeker denotes a family of advanced computational and physical systems unified by the principle of incrementally surfacing, formalizing, and fulfilling dynamic user intent in domains ranging from data-centric workflows to autonomous guidance. The Pneuma-Seeker paradigm leverages stateful, agentic architectures—whether in large language model (LLM)-driven software workflows for data discovery or in the sensor-actuator-seeker loops of time-constrained interception hardware. In its core instantiation as described in the Pneuma Project, Pneuma-Seeker operationalizes the user’s evolving information need as an explicit, manipulable shared state, advancing both interaction with structured data and physically situated control [2601.03618][2506.19522].

## 1. Foundational Concepts and System Overview

Pneuma-Seeker is a platform that iteratively transforms poorly specified or evolving information needs into concrete, actionable representations—specifically, a relational schema $T$ and an associated query sequence $Q$. At any step, the system state is a pair $(T, Q)$, expressing the current formalization of user need as a set of tables and queries. User feedback and retrieved evidence induce a sequence of updates to this state, with the objective of materializing fit-for-purpose artifacts, such as data tables or control trajectories, precisely tailored to the latent target $(T^*, Q^*)$, which remains unknown but is converged upon through interaction [2601.03618].

In autonomous guidance contexts, such as seeker-equipped interceptors, Pneuma-Seeker encompasses not only information retrieval but also the feedback-driven closure of spatial position, orientation, and control surface commands, subject to field-of-view (FOV) and physical actuation constraints [2506.19522].

## 2. Core Architectural Mechanisms

Pneuma-Seeker’s software instantiation is based on three architectural mechanisms:

- **Context Specialization:** The workflow is decomposed into specialized LLM-powered agents:
  - **Conductor**: orchestration, dialog management, action selection.
  - **IR System**: retrieval of candidate tables or documents.
  - **Materializer**: integration, code and query synthesis, repair.
  Each agent receives only the information necessary to its function, substantially reducing hallucinations and prompt entropy [2601.03618].

- **Conductor-Style Planning:** The Conductor, an LLM-driven planning agent, iteratively:
  1. Performs internal reasoning,
  2. Initiates tool calls (retrievers, materializers),
  3. Modifies the shared state $(T, Q)$,
  4. Issues user-facing messages.
  Execution is bounded by a planning horizon (empirically $i=5$ actions), after which user interaction resumes, supporting incremental, human-in-the-loop convergence.

- **Convergence Mechanism:** Central to Pneuma-Seeker is the iterative update of the shared state. At each step,
  \[
  (T^{t+1}, Q^{t+1}) = \mathcal{U}\big((T^t, Q^t), f^t, IR^t\big)
  \]
  where $f^t$ is user feedback and $IR^t$ is retrieved evidence. Convergence is empirically established when either the user declares the output sufficient or a task-specific distance metric $d((T^t, Q^t), (T^*, Q^*))$ is minimized.

## 3. Integrated Techniques in Data-Centric Pneuma-Seeker

The Pneuma-Seeker workflow tightly interweaves multiple established and novel techniques:

- **Retrieval-Augmented Generation (RAG):** Utilizes a hybrid index—HNSW vector store and BM25 inverted index—to efficiently return relevant database tables and documents, fusing structured schema, sample rows, and domain metadata into LLM prompts.

- **Agentic Framework:** Agents are dynamically orchestrated; tool outputs and query results are passed among components in a flexible, non-pipelined topology.

- **Structured Data Preparation:** The Materializer emits SQL (for DuckDB DDL/DML) or Python (Pandas, NumPy) scripts as dictated by required transformations. Error-driven code repair closes the loop: executor exceptions are re-injected into the prompt for correction.

- **Emergent Documentation:** Each $(T, Q)$ update and associated dialog forms an institutional knowledge trace, accruing accessible organizational memory.

A schematic table of architectural agents and core roles appears below:

| Agent           | Input Context        | Core Role                    |
|-----------------|---------------------|------------------------------|
| Conductor       | $(T, Q)$, feedback  | Planning, state update       |
| IR System       | Retrieval request   | Table/document retrieval     |
| Materializer    | $T$, $Q$, evidence  | Integration, code synthesis  |

## 4. Quantitative and Qualitative Evaluation

Pneuma-Seeker’s performance is measured using LLM-driven user simulation (LLM Sim) on data integration benchmarks. Evaluation metrics include:

- **Convergence Percentage:** Fraction of tasks where $(T, Q)$ matches the latent need within 15 turns.
- **Median Turns to Convergence**
- **Accuracy:** Proportion of final answers numerically matching established benchmarks.

Reported results on KramaBench’s Archaeology and Environment domains indicate Pneuma-Seeker achieves convergence on $\sim$83% (Archaeology) and $\sim$75% (Environment), outperforming LlamaIndex and static retrievers by wide margins. The system’s accuracy of 41.7% (Archaeology) and 55.0% (Environment) substantially exceeds DS-Guru and LlamaIndex baselines [2601.03618]. Latency per response is $\sim$70 s and cost is \$0.27 input/\$0.01 output per 250K tokens on O4-mini.

Qualitative findings highlight Pneuma-Seeker's ability to identify schema gaps, dispatch clarifying queries, and guide the user through ambiguous or incomplete requirements—a capability not evidenced in static pipelines.

## 5. Pneuma-Seeker in Autonomy and Control

In autonomous interception applications, Pneuma-Seeker’s principles manifest as precise, Lyapunov-stabilized, time-constrained guidance for seeker-equipped platforms. The dynamic system state $x = (r, \theta, \psi, \theta_M, \psi_M)$—relative range and angles—evolves according to nonlinear kinematics with control via lateral acceleration components $a_{My}, a_{Mz}$, subject to input-affine saturation:
\[
\dot a_{Mi} = [1 - (a_{Mi}/a_{i,\max})^n ]\,b_i - \rho a_{Mi}
\]
where $b_i$ is command input, $a_{i,\max}$ actuator limit, $n \geq 2$, $\rho > 0$ [2506.19522].

Guidance enforces a strict seeker FOV bound $|\sigma| \leq \sigma_{\max}$ by the construction of a virtual lead angle command $\sigma_d$, allocating reference headings and stabilizing acceleration-tracking errors via established backstepping procedures. Empirical simulation shows zero miss at planned impact time, no violation of actuator bounds, and a $\sim$50% reduction in control effort compared to classical schemes not modeling saturation.

For hardware realization, seeker FOV and actuator dynamics are mapped from sensor and aerodynamic look-up tables, and the control law is directly embedded in the flight loop, enabling robust time-of-flight-exact interception under realistic constraints.

## 6. Strengths, Limitations, and Future Directions

**Strengths:**
- LLM-driven orchestration of agents enables rapid accommodation of new retrieval and integration tools.
- Context specialization substantially minimizes LLM hallucination and ensures prompt relevance.
- Shared schema-query state provides an effective communication bridge between user intent and formalized data/workflow products.
- Institutional knowledge accumulates as documentation, expediting future queries and knowledge transfer.

**Limitations:**
- Latency and computational cost of LLM-driven orchestration currently preclude real-time deployment.
- System evaluation predominantly utilizes simulated (LLM-based) users; human subject studies remain necessary for validation.
- Operator action space is constrained by available tool repertoire.

**Future Work:**
- Integrate user feedback into retrieval mechanisms to reduce irrelevant candidate tables.
- Parallelize Conductor planning (e.g., Plan-over-Graph) for increased throughput.
- Expand Materializer with declarative semantic operator sets and interactive code debugging.
- Explore fuzzy convergence metrics for queries and active learning strategies for dynamic clarification.
- User-centered UI refinements for $(T, Q)$ visualization.

A plausible implication is that extensions of the Pneuma-Seeker architecture could further advance autonomous, intent-aligned workflows across domains where intent acquisition, context-constrained planning, and controlled convergence to actionable representations are mission-critical.
