The pith
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
The reading
What carries the argument
The load-bearing mechanism is the multi-stage retrieval and grounding loop of the PSA. Starting from an organization name, the agent annotates and summarizes retrieved web pages into a background statement, uses that to generate challenge-specific search queries, reranks candidate challenges by verbalized confidence and tractability, then queries a scholarly literature API for methods tied to the selected challenge. A divergent-convergent step—search broadly, prune to the five highest-confidence papers—breaks the LLM's tendency to fixate on generic problems, while confidence-weighted sampling of challenges promotes diversity. The final proposal prompt combines the background, the chosen challenge, and the pruned method set, forcing the model to justify each AI technique against the problem's constraints.
What would settle it
Have a new panel of blinded reviewers score the original, unrewritten expert summaries alongside PSA proposals with the same four-metric rubric; if the agent no longer matches the baseline, the claimed parity is an artifact of the rewriting step. A smaller test is to score original versus rewritten expert summaries directly; material score differences mean the baseline itself was moved by the rewrite.
Extended reading notes
Core claim
The central claim is that a pipeline interleaving web and scholarly retrieval with LLM summarization can turn an organization name into a full AI-for-social-good project proposal that human experts rate about as well as a proposal produced by a rigorous expert scoping process. The PSA retrieves and annotates background pages on the organization, generates and searches five candidate challenges, scores each by verbalized confidence and tractability, samples one challenge with softmax-weighted probability, retrieves up to ten scholarly papers on candidate methods, prunes to the five most applicable, and generates a solution grounded in the selected challenge and methods. On 21 expert-written fellowship project summaries, averaged human Likert scores for DS-PSA and GPT-PSA were not significantly different from the baseline, while G-PSA exceeded the baseline by 0.5476 points on average (p = 0.0058). The paper is explicit that the comparison baseline is the expert summaries after a GPT-4o formatting rewrite, and that a vanilla DeepSeek-V3 without retrieval scaffolds scores 0.619 below the baseline.
Load-bearing premise
The paper's strongest evidence for expert parity is a blind comparison against expert summaries that were first rewritten by GPT-4o for formatting; the load-bearing premise is that this rewrite preserved the quality and content of the original expert prose.
Editorial extensions
If this is right
- For a weaker base model such as DeepSeek-V3, adding PSA's retrieval scaffolding moves average human ratings from 0.619 below the expert baseline to statistically indistinguishable from it, with the paired improvement significant at p = 0.019.
- PSA roughly doubles the diversity of problem statements: GPT-4o's agent generated 57 unique problems versus 34 for the base model, and Gemini-2.0's agent generated 65 versus 31.
- Gemini-2.0-Flash, with or without the PSA pipeline, produced proposals rated above the expert baseline on average, indicating the base model's knowledge sets the quality ceiling.
- AI judges cannot replace human blind review in this setting: their scores showed very low variance across all proposals and near-zero correlation with human reviewers, so the paper's main evidence rests on the human panel.
Reading between the lines
- Placing PSA inside a human-in-the-loop workflow could yield the practical gain the paper only gestures at: the agent drafts many cheap proposals and scarce experts spend their time filtering and refining rather than writing from scratch.
- The rewrite assumption invites a direct test: scoring original, unrewritten expert summaries against PSA proposals would reveal whether the claimed parity is an artifact of GPT-4o's formatting pass.
- The same retrieve-annotate-retrieve-generate loop could transfer to other under-resourced planning tasks, such as grant writing or policy briefs, whenever an organization's public record and relevant literature are available to ground the LLM.

Referee Report
Summary. The paper proposes a Problem Scoping Agent (PSA) that combines retrieval-augmented LLM steps—background, challenge, method retrieval, and solution generation—to produce AI4SG project proposals. The authors evaluate PSA against 21 DSSG project summaries using blind human review and LLM-based evaluators, and report that DS-PSA and GPT-PSA are statistically indistinguishable from the GPT-4o-rewritten originals, that G-PSA outperforms them, and that PSA increases problem diversity relative to base LLMs. The paper also documents the failure of LLM evaluators and makes its prompts publicly available.
Significance. If the core claim holds, the paper makes a useful contribution to AI4SG: it formalizes a scoping pipeline and demonstrates a path toward automating a labor-intensive task. The paper is transparent about the failure of LLM evaluators, uses real-world DSSG projects, and reports diversity gains. However, the headline claim of 'comparable to experts' is presently conditional on an unvalidated rewriting step, and the human evaluation reporting is incomplete, so the empirical support is weaker than the abstract suggests.
major comments (4)
- [Section 4.1, Table 2] The human baseline used for all comparisons is not the original DSSG expert text but a GPT-4o-rewritten version, created with the same prompt used for final proposal generation (Appendix A). That prompt imposes content constraints—title, problem statement, proposed solution, avoidance of trivial or outreach solutions—that can alter exactly the dimensions evaluated (appropriateness, thoroughness, feasibility, expected effectiveness). The manuscript provides no evidence that the rewriting is lossless, such as human ratings of original vs. rewritten text or a content-overlap measure. Every p-value in Table 2 is against this transformed baseline, so the abstract's claim of 'comparable to those written by experts' is supported only relative to GPT-4o-processed versions. This is a load-bearing issue and needs to be addressed, either by using the original summaries directly or by validating the rewrite and reporting original-vs-rewrite scores.
- [Section 4.1, 4.2] The human evaluation is under-specified: the number of evaluators, their qualifications, the rating procedure, and inter-rater reliability (e.g., Krippendorff's alpha or ICC) are not reported. With 21 proposals and Likert-scale ratings, this information is necessary to interpret the paired t-tests and Hotelling's T2 tests; if a single rater scored all proposals, the independence assumption underlying the tests is violated, and the reported p-values are not trustworthy.
- [Section 4.2, Table 2] The conclusion that DS-PSA and GPT-PSA produce proposals 'comparable' to expert-written ones is based on failure to reject the null hypothesis (p ≈ 0.66 and 0.70 for the average). With n = 21, this is not evidence of equivalence; the tests may simply lack power. The paper should either report confidence intervals on the mean differences or use an equivalence testing approach with a pre-specified boundary, and should discuss the minimum detectable effect. This directly affects the main claim.
- [Section 4.2, Table 1] The paper honestly reports that AI-based evaluation was unsatisfactory (low variance, low correlation with human evaluation). However, the abstract states the framework was validated 'through a blind review and AI evaluations.' Since the AI evaluations are shown to be unreliable and are relegated to the appendix, the abstract should be revised to attribute the main evidence to blind human review, or the AI evaluation should be omitted from the central claim.
minor comments (3)
- [Tables 2 and 3] The notation 'µ±σ2' is ambiguous; using '±' with variance is nonstandard and may mislead readers. Consider reporting standard deviations or clarifying the header.
- [Table 2 footnote] The footnote says all p-values are from Hotelling's T2 test, but the text says per-metric p-values are from paired t-tests. Align the footnote with the text to avoid confusion.
- [Figure 2] The running example is the Memphis Fire Department, but the figure lists IBM, Conservation International, Pew Trusts, and UCSB as the organizations being searched; this is confusing and should be clarified.
Circularity Check
No significant circularity: the PSA evaluation is empirical and self-contained; the GPT-4o rewrite of the human baseline is a benchmark-validity concern, not a circular derivation.
full rationale
The paper's derivation chain is empirical: the Problem Scoping Agent is a retrieval-augmented LLM pipeline, and its outputs are compared against DSSG project summaries via blind human review. No parameter is fitted to the evaluation data, no prediction is defined in terms of its own output, and no load-bearing result rests on a self-citation. The only notable issue is that the human baseline was rewritten by GPT-4o before comparison (Section 4.1, Table 2), which could bias the comparison. However, this is a benchmark-validity concern rather than a circularity: the 'Original' row is explicitly labeled as 'original, rewritten proposals,' the scores are empirical and not forced by construction, and the paper transparently reports that LLM-based evaluations underperformed and relegates them to the appendix. The central claim is therefore not equivalent to its inputs by definition, and no circular step is present.

Artificial Intelligence for Social Good (AI4SG) is an emerging effort that aims to address complex societal challenges with the powerful capabilities of AI systems. These challenges range from local issues with transit networks to global wildlife preservation. However, regardless of scale, a critical bottleneck for many AI4SG initiatives is the laborious process of problem scoping -- a complex and resource-intensive task -- due to a scarcity of professionals with both technical and domain expertise. Given the remarkable applications of large language models (LLM), we propose a Problem Scoping Agent (PSA) that uses an LLM to generate comprehensive project proposals grounded in scientific literature and real-world knowledge. We demonstrate that our PSA framework generates proposals comparable to those written by experts through a blind review and AI evaluations. Finally, we document the challenges of real-world problem scoping and note several areas for future work.
