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 two-stage Location--Inference framework that first localizes high-confidence task anchors and then recovers broader task-relevant context over the repository's multi-relational structure while respecting budget constraints.
What would settle it
An experiment on SWE-bench Verified or the industrial task set in which DeepDiscovery is used but the solve rate stays flat or drops and Full Recall Rate shows no improvement or declines.
Extended reading notes
Core claim
DeepDiscovery is a task-level repository-understanding method that employs a two-stage Location-Inference framework to localize high-confidence task anchors and recover broader task-relevant context over multi-relational repository structure under budget constraints. Across medium-scale tasks it produces the best file recovery quality among five baselines without offline preprocessing. On organization-internal industrial tasks it raises Full Recall Rate by 1.6 to 9.2 percentage points on large subprojects and 2.5 to 7.4 percentage points on medium-scale subprojects. In end-to-end evaluation on SWE-bench Verified a system using DeepDiscovery reaches a 78.6 percent Solve Rate, 8.2 points above
Load-bearing premise
The multi-relational repository structure supplies enough information to recover the needed broader context under budget limits without adding significant noise or omitting critical dependencies.
Editorial extensions
If this is right
- On 27 medium-scale tasks DeepDiscovery delivers the highest file recovery quality among five representative baselines without requiring offline preprocessing.
- In production-scale industrial settings it raises Full Recall Rate by absolute gains of 1.6 to 9.2 percentage points on large subprojects and 2.5 to 7.4 percentage points on medium-scale subprojects.
- Equipping an AI coding system with DeepDiscovery produces a 78.6 percent Solve Rate on SWE-bench Verified, an 8.2 percentage point gain over the baseline system.
- Stronger task-level repository understanding improves coding-agent performance on complex software engineering tasks.
Reading between the lines
- The same anchor-and-path recovery pattern could be tested on repositories outside the evaluated industrial ecosystem to check whether the gains hold when relational density differs.
- If the method is applied to multi-language or distributed codebases it might reveal whether the multi-relational assumption still supplies sufficient signals without extra preprocessing.
- Combining the recovered paths with existing fragment-based retrievers could produce a hybrid system that further reduces missing dependencies in agent workflows.
Editorial analysis
A structured set of objections, weighed in public.
Referee Report
Summary. The paper introduces DeepDiscovery, a two-stage Location-Inference framework for task-level context recovery in large industrial codebases. It localizes high-confidence task anchors and recovers broader task-relevant context over multi-relational repository structures under budget constraints. Evaluations on 27 medium-scale method-level tasks, 27+40 internal industrial tasks, and SWE-bench Verified report best-in-class file recovery quality, Full Recall Rate gains of 1.6-9.2 pp on large subprojects (2.5-7.4 pp on medium), and an 8.2 pp improvement to 78.6% solve rate over baseline.
Significance. If the empirical gains hold under the reported conditions, the work demonstrates that multi-relational path recovery can measurably improve repository understanding for coding agents without offline preprocessing, with results spanning controlled benchmarks, production-scale internal tasks, and end-to-end SWE-bench evaluation. This provides concrete evidence on a practical scaling challenge for LLM-based SE systems.
major comments (3)
- [§5.2] §5.2 (internal industrial tasks): The Full Recall Rate gains (1.6-9.2 pp on large subprojects) are attributed to the multi-relational structure and two-stage recovery, yet the section provides no ablation that isolates the inference stage or compares against single-relation baselines; without this, the load-bearing role of the multi-relational graph versus simpler retrieval remains unverified.
- [§4] §4 (Location-Inference framework): The description of path recovery under budget constraints does not include a formal characterization or guarantee of when the multi-relational graph contains the necessary task-relevant paths without omissions or noise; this directly bears on whether the reported recall and solve-rate improvements follow from the claimed mechanism.
- [§5.3] §5.3 (SWE-bench Verified): The 78.6% solve rate (+8.2 pp) is presented as end-to-end evidence, but the evaluation does not report whether the context-recovery component was ablated or whether gains persist when the underlying multi-relational graph is incomplete, leaving the central claim vulnerable to the skeptic concern.
minor comments (2)
- [Abstract] The abstract states '27 medium-scale tasks' in two separate sentences; clarify whether these refer to the same set or distinct evaluations.
- [§3] Notation for 'Full Recall Rate' is introduced without an explicit equation or definition in the early sections; add a precise definition before the results tables.

Referee: [§5.2] §5.2 (internal industrial tasks): The Full Recall Rate gains (1.6-9.2 pp on large subprojects) are attributed to the multi-relational structure and two-stage recovery, yet the section provides no ablation that isolates the inference stage or compares against single-relation baselines; without this, the load-bearing role of the multi-relational graph versus simpler retrieval remains unverified.
Authors: We agree that an explicit ablation isolating the two-stage inference and multi-relational components on the internal tasks would strengthen attribution. The current section relies on comparisons to external baselines, which provide supporting but indirect evidence. In the revised manuscript we will add a dedicated ablation subsection comparing the full framework against single-relation variants and a no-inference baseline on the 27+40 internal tasks. revision: yes
-
Referee: [§4] §4 (Location-Inference framework): The description of path recovery under budget constraints does not include a formal characterization or guarantee of when the multi-relational graph contains the necessary task-relevant paths without omissions or noise; this directly bears on whether the reported recall and solve-rate improvements follow from the claimed mechanism.
Authors: The manuscript presents Location-Inference as a practical, budget-constrained heuristic rather than a formally guaranteed procedure; no formal characterization or completeness guarantee is claimed. We will revise §4 to explicitly note the empirical, heuristic nature of the method and add a short discussion of observed conditions (based on the reported evaluations) under which path recovery succeeds or degrades. revision: yes
-
Referee: [§5.3] §5.3 (SWE-bench Verified): The 78.6% solve rate (+8.2 pp) is presented as end-to-end evidence, but the evaluation does not report whether the context-recovery component was ablated or whether gains persist when the underlying multi-relational graph is incomplete, leaving the central claim vulnerable to the skeptic concern.
Authors: We acknowledge that an ablation of the context-recovery component on SWE-bench Verified would directly address the concern. The current results are end-to-end; performing a full ablation requires additional controlled runs. We will add a limitations paragraph discussing this point and, where data permits, report a partial ablation using the existing graph-construction variants. revision: partial
Circularity Check
No circularity; empirical evaluation is self-contained
full rationale
The paper introduces DeepDiscovery as a two-stage Location-Inference method for repository context recovery and reports direct empirical gains on 27 medium-scale tasks, 40 large-scale industrial tasks, and SWE-bench Verified (78.6% solve rate, +8.2 pp). No equations, fitted parameters renamed as predictions, self-citations invoked as uniqueness theorems, or ansatzes appear in the provided text; the central claims rest on measured recall rates and end-to-end performance rather than any derivation that reduces to its own inputs by construction.

Large language models have shown strong performance on software engineering (SE) tasks, yet understanding large industrial repositories remains challenging. Existing methods often retrieve only local fragments and fail to recover the broader task-relevant context needed for complex repository-level tasks. We present DeepDiscovery, a task-level repository-understanding method for large industrial codebases. DeepDiscovery uses a two-stage \textit{Location--Inference} framework to localize high-confidence task anchors and recover broader task-relevant context over multi-relational repository structure under budget constraints. Across controlled method-level evaluation, organization-internal industrial repository-understanding scenarios, and end-to-end evaluation on SWE-bench Verified, DeepDiscovery consistently improves task-relevant file recovery and downstream SE performance. On 27 medium-scale tasks, DeepDiscovery achieves the best file recovery quality among five representative baselines without offline preprocessing. On organization-internal industrial tasks from a production-scale integrated codebase ecosystem, including 27 medium-scale tasks and 40 large-scale tasks, DeepDiscovery improves Full Recall Rate across multiple AI coding systems, with absolute gains ranging from 1.6 to 9.2 percentage points on large subprojects and from 2.5 to 7.4 percentage points on medium-scale subprojects. In a controlled end-to-end evaluation on SWE-bench Verified, a system equipped with DeepDiscovery achieves a 78.6\% Solve Rate, outperforming the corresponding baseline by 8.2 percentage points. These results suggest that stronger task-level repository understanding can improve coding-agent performance on complex SE tasks.
