Summary

  • New blog post: "Deep Research Trajectories with NeMo Data Designer and MCP Tool Use"
  • Reproduces the OpenResearcher paradigm (Chen et al., 2026) using Data Designer's MCP tool-calling pipeline
  • Results comparing Claude Opus 4.5 (75% accuracy) and Nemotron Nano 3 (52% accuracy) on 64 MuSiQue multi-hop questions (2/3/4-hop)
  • Documents rough edges with open-weight model tool calling on vLLM (GPT-OSS-120B Harmony format, Kimi K2.5)
  • Includes full reproducible source: pipeline config, corpus preparation script, and BM25S retrieval MCP server

Test plan

  • Verify blog renders correctly with mkdocs serve
  • Check trajectory visualization renders in dark/light mode
  • Verify all external links resolve
  • Review code foldables expand/collapse correctly

blog: deep research trajectories with NDD and MCP tool use
2d1132a 
OpenResearcher-style pipeline for generating multi-turn research
trajectories using Data Designer's MCP tool-calling capabilities.
Includes results comparing Claude Opus 4.5 and Nemotron Nano 3 on
64 MuSiQue questions (2/3/4-hop), trajectory visualization, analysis
of the open-model tool-calling ecosystem, and full reproducible source.

blog: move post to devnotes and add nav entry
53729ee 
Move deep-research-trajectories.md from docs/blog/posts/ to
docs/devnotes/posts/ to match the project's dev notes convention.
Add nav entry in mkdocs.yml alongside the existing RQA post.

Greptile Overview

Greptile Summary

Adds comprehensive blog post "Deep Research Trajectories with NeMo Data Designer and MCP Tool Use" to the dev notes section, along with navigation updates.

Key additions:

  • New blog post (deep-research-trajectories.md): 1070-line comprehensive guide reproducing the OpenResearcher paradigm using Data Designer's MCP tool-calling pipeline
  • Includes complete reproducible source code (pipeline config, corpus preparation script, BM25S retrieval MCP server)
  • Documents experimental results comparing Claude Opus 4.5 (75% accuracy) vs Nemotron Nano 3 (52% accuracy) on 64 MuSiQue multi-hop questions
  • Features interactive trajectory visualization with custom CSS/HTML that adapts to dark/light mode
  • Discusses rough edges with open-weight model tool calling on vLLM (GPT-OSS-120B Harmony format issues, Kimi K2.5 compatibility problems)
  • Recipe card addition (cards.md): New "Basic MCP Tool Use" recipe card entry with proper formatting
  • Navigation updates (mkdocs.yml): Added entries for the new blog post and Basic MCP recipe

Technical quality:

  • All external links are valid and properly formatted
  • Internal link to ../../concepts/tool_use_and_mcp.md is correctly formed
  • Author etramel is properly defined in .authors.yml
  • Code blocks are properly balanced (22 fence markers = 11 pairs)
  • Referenced files for the Basic MCP recipe card exist (basic_mcp.md, basic_mcp.py)
  • HTML/CSS visualization uses inline styles appropriate for MkDocs material theme
  • No @ symbols need escaping (all in code blocks)

Confidence Score: 5/5
  • This PR is safe to merge with no issues found
  • Documentation-only PR that adds a well-crafted blog post with complete working examples. All links verified, formatting correct, author properly configured, and navigation properly updated. No code changes to runtime systems.
  • No files require special attention

Important Files Changed

Filename Overview
docs/devnotes/posts/deep-research-trajectories.md New comprehensive blog post documenting deep research trajectories using MCP tool-calling pipeline with OpenResearcher paradigm reproduction, includes complete working examples and detailed results
docs/recipes/cards.md Added new recipe card for Basic MCP Tool Use with proper formatting and links
mkdocs.yml Added navigation entries for new blog post and Basic MCP recipe

@eric-tramel @claude
