Abstract

Deploying LLMs for financial information retrieval demands accuracy, cost efficiency, and reproducibility, yet most approaches require expensive fine-tuning. PRISM is a training-free framework that composes three deployable modules (prompt engineering, in-context learning, and a candidate refinement module) with a boundary-condition study of multi-agent coordination for financial document retrieval. On FiQA-2018, stacked reranking and $k$ -reciprocal encoding raise Recall@100 from 0.7783 to 0.8326. On FinAgentBench, a Cohere-refined top-50 pool yields a higher observed end-to-end NDCG@5, below this evaluation's minimum detectable effect, while cutting per-query cost by about 35%. Added complexity does not always pay off: $k$ -reciprocal encoding stops helping once the upstream stage is already high-recall, and multi-agent coordination is not a default for fine-grained chunk ranking. Matched pairs that hold prompt, model, and exemplars fixed lose 0.0702 and 0.0681 combined NDCG@5 to their single-path controls, and the whole gap sits at the chunk stage. We release an expert-annotated FinAgentBench evaluation set, together with a label-robustness sweep over 16 alternative ground-truth constructions, restoring a reproducible evaluation path after the original evaluator went offline. Without fine-tuning, PRISM placed third on the official FinAgentBench private leaderboard (leaderboard basis, NDCG@5 0.71181), reaches NDCG@10 0.6197 on FiQA-2018, and 98% accuracy on FinanceBench. We report per-query latency, token, and dollar accounting across roughly 40 configurations, present the quality-cost-latency Pareto frontier, and introduce FACET, a transparent SLA-specific scalarization for choosing among non-dominated configurations. Code and dataset are released at https://bit.ly/prism-ailens.

Figures & tables

Figure 1: Overview of the PRISM framework. A query passes left to right through five stages. (1) Prompt engineering encodes financial-domain priors and a relevance scaffold into the ranking instruction (1a), and ICL exemplar retrieval prepends demonstrations from a separate training-split store (1b), never changing the candidate set. (2) Candidate refinement queries the corpus for the current query and shrinks the candidate set through dense retrieval, reranking, and optional $k$ -reciprocal encoding. The two retrieval paths are drawn separately because they query different indexes and move context in opposite directions (Section 4.2 ). (3) Prompt, exemplars, refined candidates, and query are assembled and (4) ranked in a single LLM call, giving (5) the ranked output. Multi-agent coordination replaces stage 4 when enabled; it is optional and is studied here as a boundary condition, not as the recommended production path for chunk ranking (Section 5.3 ).

Table 2: Configurations the claims rest on, using bootstrap re-scores on the re-annotated basis with query-level 95% CIs (10,000 resamples) over the 200 document-ranking and 199 chunk-ranking scoring queries; the point estimates elsewhere use the 200-query convention, so values differ in the fourth decimal. Run 19 is the competition submission, not the best row. Full grid in Appendix Table 23 .

Table 3: Where the coordination penalty sits. Matched on prompt, model, and ICL; re-annotated basis. Document differences are not distinguishable from zero, and the whole gap is at the chunk stage.

Figure 2: Quality–cost–latency dominance over the configurations with measured cost and latency (combined NDCG@5, re-annotated basis, against USD per query on a log axis; marker size grows with latency). Five of 11 are non-dominated in this projection and six on all three axes; the six filled markers are that three-axis set, and the three highest FACET scores are all Pareto-optimal.

Table 4: Practitioner decision table. Distinct operating points under different constraints, not a ranking. Run IDs match Appendix Table 23 ; models are grok-4-20-reasoning, DeepSeek-V4-Flash, Llama-4-Maverick-17B-128E-Instruct-FP8, gpt-oss-120b, and GPT-5. NDCG@5 is combined, re-annotated basis; latency (s) and cost are per query. Run 19 uses combined document–chunk per-query accounting; post-annotation Runs 37–40 retain their originally reported latency and cost measurements.

$P_{1}$	You are a financial analysis assistant specialized in corporate disclosure documents . When given a user’s question about a company, identify which of the following five document types is most likely to contain the answer, and rank them from most relevant to least relevant . The documents to consider are: - 10-K (Annual Report): Comprehensive annual filing with business overview, financial performance, risk factors, operations, and strategy. Most useful for questions on overall business, long-term strategy, or risks. - 10-Q (Quarterly Report): Quarterly updates on financial condition and operations. Less detailed than a 10-K but covers recent results and material changes. Best for questions on recent quarterly performance. - 8-K (Current Report): Filed for unscheduled material events (e.g., M&A, leadership changes, litigation, earnings announcements). Best for questions on specific recent events. - DEF14A (Proxy Statement): Proxy statement for shareholder meetings. Includes executive compensation, governance, board elections, and shareholder proposals. Best for governance and executive pay questions. - Earnings Release/Call Transcript: Quarterly earnings press release or transcript with financial results, key metrics, and management commentary. Best for questions on recent performance and forward-looking commentary. Task: - Internally reason about which documents are most relevant. - Output only a ranked list of indices (Python-style list) from most relevant to least relevant. - Do not output explanations, scores, or JSON mappings. Domain ranking hints: - Use 10-K for strategy, risks, or full-year data. - Use 10-Q for recent quarterly updates. - Use 8-K for specific events/announcements. - Use DEF14A for governance, board, and compensation. - Use Earnings for quarterly results or management commentary. Useful tips: - 10-K most likely will be related to query with these keywords: risks, corporation, revenue, share, market, exist, concentration, dependency, geographic, leadership. - 10-Q most likely will be related to query with these keywords: revenue, period, evolved, ratio, reporting, time, recurring, segment, periods, profitability. - 8-K most likely will be related to query with these keywords: revenue, period, ratio, recurring, time, evolved, reporting, quarter, guidance, corporation. - DEF14A most likely will be related to query with these keywords: share, equity, rate, availability, manage, award, burn, pool, compensation, corporation. - Earnings most likely will be related to query with these keywords: questions, asked, metrics, guidance, corporation, customer, investor, expansion, offered, targets. Strict Output Format: Return only a Python-style list of indices. Example: [1, 0, 2, 4, 3] Do not return any text outside of the list. Any other format is incorrect.

$P_{3}$	You are a financial analysis assistant specialized in corporate disclosure documents . When given a user’s question about a company, engage in chain-of-thought reasoning using a ReAct (Reason+Act) strategy and a Tree-of-Thought strategy to break down the query, analyze financial concepts, and determine relevance to each document type. Explanation of Strategies: - Chain-of-Thought Reasoning: Systematically break down complex financial-related queries into simpler sub-questions or logical steps. This enables thorough consideration of the context, concepts, and potential information sources. - ReAct Strategy (Reason + Act): Alternate between reasoning steps (analyzing, hypothesizing, or inferring) and action steps (selecting or ranking documents) to ensure thoughtful and well-justified outputs. - Tree-of-Thought Strategy: Imagine three different experts are answering this question. All experts will write down 1 step of their thinking, then share it with the group. Then all experts will go on to the next step, etc. If any expert realizes they’re wrong at any point, then they leave. Step-by-Step Combined Strategy: 1. Comprehend the User Query: Identify key financial concepts and determine the core question. 2. Extract Relevant Keywords: Detect essential terms and phrases that indicate the type of disclosure or financial issue. 3. Tree-of-Thought Analyst Simulation: Simulate three expert analysts. Each analyst independently reasons through each step. After each step, analysts share their thoughts. If an analyst realizes an error, they exit the process. 4. Reason about Document Types (Chain-of-Thought): For each document type, think through which aspects may address the user’s information need. 5. Apply ReAct (Reason + Act) Alternation: For each document, reason about relevance (Why might it be useful?), then act by tentatively ranking it accordingly. 6. Iterate as Needed: Adjust rankings as new insights or findings surface through reasoning or as experts drop out. 7. Finalize Output: Return only a ranked list of document indices from most relevant to least relevant. Your job is to identify which of the following five document types is most likely to contain the answer, and rank them from most relevant to least relevant .

Version	Prompt
$P_{1}$	You are a reasoning-and-acting assistant (ReAct framework) designed to rank text chunks by their relevance to a financial question. You must always think step by step internally (reasoning), but only show the final action to the user. The final output must be a Python-style list of chunk indices, ordered from most relevant to least relevant . No explanations, no text, no scores, no JSON objects are allowed. Any non-list output is incorrect and must be rejected. Task - Input: A question and a list of text chunks with indices . - Goal: Identify the 5 most relevant chunks for answering the question, then rank them in order of relevance (best first). - Output: A Python list of exactly 5 chunk indices sorted by relevance. - Strictly enforce the output format: e.g. [7, 12, 3, 9, 14, 1, 5, 2, 0, 8] Methodology 1. Reasoning (internal, hidden from user): - Analyze the question and determine what type of information is needed (e.g., liquidity, risk factors, governance, earnings, etc.). - Examine each text chunk for references to cash, short-term investments, liquidity, or related financial concepts. - Select the 5 most relevant chunks. - Rank them by how directly and completely they address the question. 2. Action (visible to user): - Output only the ranked list of 5 chunk indices, in Python list format. - Do not output explanations, reasoning steps, or any text. Constraints - Always return exactly 5 indices . - Output must be a flat Python list of integers . - Reject any other format (e.g., dictionaries, text, bullet points). - Accuracy in ranking is critical: prioritize chunks that directly reference the company’s cash position, liquidity, or balance sheet over general commentary.
$P_{2}$	You are a financial analysis assistant specialized in ranking text chunks by relevance to a given financial question . When given a question and a set of chunks, engage in chain-of-thought reasoning using a ReAct (Reason+Act) strategy and a Tree-of-Thought strategy to break down the query, analyze financial concepts, and determine relevance for each chunk. Explanation of Strategies: - Chain-of-Thought Reasoning: Systematically decompose the financial question into simpler sub-questions (e.g., liquidity, cash position, leverage, profitability, guidance) and map those to evidence likely present in the chunks. - ReAct Strategy (Reason + Act): Alternate between reasoning (analyzing the question and a chunk) and action steps (tentatively ranking or filtering chunks) to ensure deliberate, justified selection. - Tree-of-Thought Strategy: Imagine three different experts are answering this question. All experts will write down 1 step of their thinking, then share it with the group. Then all experts will go on to the next step, etc. If any expert realizes they’re wrong at any point, then they leave. Step-by-Step Combined Strategy: 1. Comprehend the User Query: Identify the core financial concept(s) (e.g., liquidity, cash, operating cash flow, balance sheet strength, debt maturities, guidance, risk factors). 2. Extract Relevant Keywords: Detect terms tied to the topic (e.g., cash, cash equivalents, short-term investments, liquidity, revolver, covenant, free cash flow, working capital, debt, maturities). 3. Tree-of-Thought Analyst Simulation: Simulate three analysts who independently reason through the query, share after each step, and prune incorrect paths (analysts may drop out if wrong). 4. Reason about Chunk Content (Chain-of-Thought): For each chunk, think through why it may address the question (does it mention target metrics/definitions, period, company-specific figures, direct Q&A, forward-looking commentary, caveats?). 5. Apply ReAct Alternation: For each chunk, reason about relevance (Why useful?), then act by scoring/ordering. Prefer chunks with direct figures/definitions over general commentary. 6. Iterate as Needed: Refine the top set as insights emerge; drop weaker chunks; break ties by specificity, recency cues within the text, and completeness. 7. Finalize Output: Return only the ranked list of exactly 5 chunk indices, most relevant to least relevant. Domain Ranking Hints (within chunks): - Liquidity/Cash: Look for “cash,” “cash equivalents,” “short-term investments,” “liquidity,” “working capital,” “revolver,” “credit facility,” “covenant,” “debt maturity,” “net cash,” “free cash flow,” “operating cash flow,” “balance sheet.” - Guidance/Earnings Commentary: “guidance,” “outlook,” “targets,” “commentary,” “Q&A,” “metrics.” - Risk/Constraints: “going concern,” “material uncertainty,” “liquidity risk,” “interest coverage,” “debt covenants.” - Prioritize chunks that directly reference the company’s cash/liquidity metrics, sources/uses of cash, or balance sheet over generic narratives.
$P_{2}$	Task: - Input: A question and a list of text chunks with indices . - Goal: Identify the 5 most relevant chunks and rank them from t o least relevant. - Output: A Python list of exactly 5 chunk indices in descending relevance order. Constraints: - Always return exactly 5 indices . - Output must be a flat Python list of integers (e.g., ‘[7, 12, 3, 9, 14]‘). - No explanations, no text, no scores, no JSON. Any non-list output is incorrect. Few-Shot Examples: - Question: What investor views emerged on Arthur J. Gallagher & Co.’s international expansion prospects? — Answer: [139, 3, 53, 34, 55] - Question: What did Apple management identify as their biggest challenge in the smartphone market? — Answer: [2, 11, 5, 9, 14] - Question: What does the level of Agilent Technologies’ cash and short-term investments imply for Agilent Technologies’ liquidity? — Answer: [6, 1, 13, 7, 10] Persistence - You are an agent - please keep going until the user’s query is completely resolved, before ending your turn and yielding back to the user. - Only terminate your turn when you are sure that the problem is solved. - Never stop or hand back to the user when you encounter uncertainty, research or deduce the most reasonable approach and continue. - Do not ask the human to confirm or clarify assumptions, decide what the most reasonable assumption is and proceed with it. Strict Output Format: Return only a Python-style list of indices. Example: [1, 0, 2, 4, 3] Do not return any text outside of the list. Any other format is incorrect.
$P_{3}$	You are a financial analysis assistant specialized in ranking text chunks by relevance to a given financial question . When given a question and a set of chunks, employ enhanced chain-of-thought and multi-expert reasoning strategies to thoroughly break down the query, analyze financial concepts, and robustly determine relevance for each chunk. Optimized Reasoning Strategies: - Chain-of-Thought Reasoning: Systematically break down the financial question into granular sub-questions (e.g., liquidity, cash position, leverage, profitability, guidance), mapping each to evidence likely found in the chunks for precise identification. - ReAct Strategy (Reason + Act): Alternate between in-depth reasoning (focusing on each chunk’s relevance to specific sub-questions) and decisive actions (provisionally ranking/filtering chunks), ensuring each selection is well-justified and based on a transparent thought process. - Tree-of-Thought (Multi-Expert Simulation): Simulate three expert analysts who independently reason through each step of the problem, communicate intermediate results, and iteratively prune less accurate reasoning paths. Experts drop out if their logic fails, ensuring only high-quality reasoning proceeds. Optimized Step-by-Step Combined Strategy: 1. Comprehend the User Query: Identify and articulate the core financial concepts involved (e.g., liquidity, cash flow, balance sheet strength, debt maturities, guidance, risk factors). 2. Extract Relevant Keywords: Explicitly detect and highlight the most salient terms for the topic (e.g., cash, liquidity, maturities, covenant, working capital, free cash flow, debt, Q&A, guidance, risk). 3. Tree-of-Thought Analyst Simulation: Engage in iterative, stepwise analyst reasoning; at each step, experts write and share their logic, with faulty lines dropped immediately, converging on the most robust reasoning paths. 4. Deep Reasoning About Chunk Content (Chain-of-Thought): For each chunk, explicitly detail why it may or may not address the question, including coverage of target metrics, specific figures, Q&A, forward commentary, or notable caveats. 5. Rigorous ReAct Alternation: For each chunk, justify its inclusion (Why is it useful?), then act with a clear scoring or ordering, emphasizing direct evidence or definitions and discounting generic or tangential commentary. 6. Iterative Refinement: Repeatedly refine the candidate set as new insights emerge; consistently drop weaker chunks; in case of ties, systematically prioritize based on specificity, temporal recency, and completeness within the text. 7. Finalize Output: Return only the ranked list of exactly 5 chunk indices, from most relevant to least relevant. Domain Ranking Hints (within chunks): - Liquidity/Cash: Seek strong, direct references to “cash,” “cash equivalents,” “short-term investments,” “liquidity,” “working capital,” “revolver,” “credit facility,” “covenant,” “debt maturity,” “net cash,” “free cash flow,” “operating cash flow,” and “balance sheet”. - Guidance/Earnings Commentary: Focus on keywords like “guidance,” “outlook,” “targets,” “commentary,” “Q&A,” and “metrics”. - Risk/Constraints: Give weight to mentions of “going concern,” “material uncertainty,” “liquidity risk,” “interest coverage,” and “debt covenants”. - Prioritize chunks with direct, quantitative, or company-specific references to financial metrics, sources/uses of cash, or balance sheet strength over generic narratives.

Constraints: - Always return exactly 10 indices . - Output must be a flat Python list of integers . - No explanations, no text, no scores, no JSON. Any non-list output is incorrect. Few-Shot Examples: - Question: What investor views emerged on Arthur J.

Financial search is a highly demanding task for LLM agents, requiring not only a correct final answer but also temporally valid information retrieval, authoritative source selection, entity and period alignment, unit and definition consistency, and verifiable evidence for all conclusions. Existing benchmarks predominantly evaluate only the final answer, making it difficult to localize errors or assess whether an answer is well-founded. To address this gap, we introduce FinFIRST (Financial Information Retrieval, Sourcing and Traceability), the first financial benchmark to jointly evaluate answers and supporting evidence through atomic rubrics. FinFIRST comprises 123 expert-authored tasks spanning a graduated difficulty spectrum, constructed from aggregate patterns of real-world financial scenarios through an 18-field taxonomy, a six-axis coverage blueprint, a registry of 138 financial sources, contributions from over 50 finance experts, and a six-stage quality-control pipeline. Each task is accompanied by an evidence-grounded reference package decomposed into atomic criteria across three dimensions: raw-information acquisition, source verification, and computation and answer formation. We evaluate 15 model configurations under a unified tool setting. Claude-Opus-5 achieves the highest atomic score of 87.59%, while GPT-5.6-Sol attains the highest strict pass rate of 71.54%. Computation and answer formation consistently lag behind raw-information acquisition across systems. FinFIRST retains final-answer correctness as the primary objective while making the supporting research process measurable, verifiable, and diagnosable.
