NEX v5.61 improves how agents navigate large repositories, interpret tool results, and manage large volumes of command output. This release also expands web search capabilities across multiple agents and further improves prompt caching for Anthropic models, including Amazon Bedrock.
Faster Repository Navigation
NEX now includes repo-wide grep and glob tools designed specifically for navigating large codebases. Agents can search across an entire repository without relying on generic shell commands, while respecting nested .gitignore rules and prioritizing recently modified files where appropriate. These tools make it easier to locate:
- RTL and verification sources
- Configuration files
- Module and symbol references
- Generated artifacts
- Files matching repository-wide patterns
The result is faster, more focused codebase exploration with less unnecessary context.
Keep Shell Output Under Control
Large shell commands can generate thousands of lines of output, much of which is rarely useful to the active model context. NEX now truncates oversized shell output while preserving the complete result as an artefact under the .nex directory. Agents still receive the relevant portion of the output, while full logs remain available when deeper inspection is required.
This helps keep long-running workflows focused without discarding potentially useful diagnostic information.
Richer Results from EDA Tools
Tool results from Vivado, Questa, VCS, and Radiant now expose structured, curated engineering data directly in the NEX interface. Instead of presenting only raw tool output, NEX can surface useful information such as:
- Coverage scores from URG reports
- FPGA device resources and package pin counts
- Vivado-reported design data
- Questa, VCS, and Radiant result summaries
- Relevant arguments used for completed tool calls
This makes results easier to inspect and gives engineers better visibility into what each agent actually executed and discovered.
Web Search Across More Agents
Web search is now available to all agents. This allows NEX to retrieve external technical information when repository context alone is not sufficient, while keeping search integrated into the active workflow.
Improved Anthropic and Bedrock Caching
Conversation-history caching for Anthropic models has been expanded using a moving cache breakpoint, allowing more of a long-running session to benefit from cached context. Prompt caching for Claude models running through Amazon Bedrock has also been restored and extended to conversation history.
For iterative workflows with substantial accumulated context, this can reduce repeated prompt processing and improve cost efficiency.
More Robust Session and Tool Handling
This release also includes several reliability improvements across session persistence and tool execution. NEX can now repair certain malformed tool-call histories when loading a session, preventing previously interrupted runs from leaving sessions unusable. Temporary scripts and logs are also consolidated under the .nex directory, keeping project workspaces cleaner while preserving diagnostic artefacts when needed.
NEX v5.61 makes repository-scale workflows easier to navigate, keeps large tool outputs under control, and surfaces more useful data directly where it matters.
