Draft branch for the copilot-offline-eval MCP tool-selection harness. Rewrites the search_issues tool + query param descriptions to steer models toward natural-language queries instead of qualifier/boolean syntax, matching the end-state of the issue-search experiment (plan-track-agentic-toolkit#415). Not intended to merge: it exists so the eval can build a container from this branch and measure query-formation against the current lexical wording. Toolsnaps regenerated.
Realign the eval stand-in to the exact strings shipped by the experiment PR (github-mcp-server-remote#911) semantic variant, rather than the stronger end-state wording, so the eval measures what the experiment actually ships: - tool desc: 'Best for conceptual or paraphrased queries...' (not the imperative 'Write the query as a natural-language description...') - query param: 'Write it as natural language for semantic and hybrid variants.' (drops 'rather than exact keywords or boolean operators') Toolsnaps regenerated.

Draft branch for the copilot-offline-eval MCP tool-selection harness. It exists so the eval can containerise this branch (
github-mcp-server-branchinput) and measure query formation against the current lexical wording. Not intended to land.What it changes
Rewrites the
search_issuestool description andqueryparam description to steer models toward natural-language queries instead of qualifier/boolean syntax:…using natural-language semantic matching. Write the query as a natural-language description of what you're looking for… Avoid boolean OR operators, which fall back to lexical keyword search.queryparam:Write it as a natural-language description… rather than exact keywords or boolean operators.This matches the end-state of the issue-search experiment (github/plan-track-agentic-toolkit#415): once
search_issuesdefaults to semantic, the description should stop advertising lexical syntax.Why
The experiment showed models over-produce boolean/qualifier queries that trip the monolith's semantic→lexical fallback. Before committing to the remote-side wording, we want offline eval evidence that the reworded description actually shifts query formation (
QUERY_AGENT_RATING/QUERY_WORD_MATCH) without regressing legitimate qualifier queries (guard cases in the benchmark PR).Validation
