First implication: Teams can instrument and evaluate intermediate information stages alongside patch correctness. The reported ordering can motivate local experiments, but should not be assumed universal. First watch condition: Whether evaluations on other benchmarks and agent setups reproduce the reported ordering. Also watch whether agent-extracted signals close the measured gap with oracle signals. The paper releases code and an oracle-signal dataset, which could support replication; their availability alone does not validate transfer beyond the reported experiments.
Thesis
Intermediate information signals are measurable contributors to repository-level agent success, not merely incidental traces of exploration.
Observed facts
The paper selects five signals: Reproduction Test, Regression Test, Edit Location, Execution Context, and API Usage.
1It reports the contribution ordering Reproduction Test > Execution Context approximately equal to API Usage > Edit Location > Regression Test.
1The authors compare agent-extracted signals with oracle counterparts and quantify the gap between them.

Mechanism
The researchers provide oracle or stronger-agent-extracted signals to a main agent as if they came from a sub-agent or workflow stage, then use resulting task-success gains to estimate signal contribution.
Why now
Repository-level agents depend on exploration, localization, API retrieval, and testing before editing, while these capabilities can be studied through concrete signals rather than inferred only from an end result.
Implications
Teams can instrument and evaluate intermediate information stages alongside patch correctness.
The reported ordering can motivate local experiments, but should not be assumed universal.
Evidence boundary
The findings are experimental results from the paper’s methodology and tasks; they do not establish a universal ranking across agents, benchmarks, or production repositories.
Watch conditions
Whether evaluations on other benchmarks and agent setups reproduce the reported ordering.
Whether agent-extracted signals close the measured gap with oracle signals.
