What they built.
LangChain's dynamic-subagent article publishes a specific file-review demonstration with a linked execution trace. The example distributes TypeScript files to reviewers and combines their findings, making it a concrete explanation of delegation rather than a generic claim that agents can help developers.
The evidence supports an orchestration demonstration, not a conclusion that every security problem was found. The source article was readable during research, while the linked trace required a client-rendered interface. Readers can inspect that original trace, but this directory did not replay the run.

Open the published review traceHow the tools work together
A script can explicitly dispatch work across a discovered set of files and collect results into one report. This helps make coverage a property of the workflow. Individual findings remain model judgments, however, and must be checked against code and reproducible evidence.
Workflow at a glance
Identify the source files
The demonstration discovers TypeScript files under src.
Delegate the reviews
An orchestration script dispatches a reviewer for each file in parallel.
Combine findings
The agent assembles severity ratings and relevant code locations into one prioritized report.
How you could adapt the idea
Try the pattern on a small repository whose expected issues are already known. Record which files were included, preserve each review result, and compare the combined findings with a manual baseline. Avoid interpreting the number of delegated workers or reported issues as a quality measure.
Effort, cost and limitations
- Effort
- Requires a configured agent, tool access and interpreter middleware; demonstration implementation time is not disclosed.
- Cost
- Not disclosed by the source; delegated model calls and infrastructure add costs.
A demonstration of orchestration, not an independent security audit or vulnerability-detection benchmark.
Source article was inspected; the linked trace's full contents were not independently parsed or replayed.
