NEVER post comments to GitHub PRs or issues (via gh, API, or any other mechanism) without first showing the exact text to the user and getting explicit approval.

NEVER push to a remote without explicit approval. Prefer new commits over amending (exceptions: asked to amend, or minor fix to an unpushed broken commit). Never squash or force-push unless explicitly told.

When creating PR/issue comments or descriptions containing non-ASCII characters (em-dashes, μ, etc.), write the content to a temp file with the create tool and use --body-file to avoid UTF-8/codepage corruption on Windows. Use | entity for literal | inside markdown table cells. Avoid PowerShell expandable strings (@"..."@) for markdown with backticks; use literal here-strings (@'...'@).

Objective: Using MCP tools as appropriate I want you to analyze active issues in dotnet/runtime repo to perform a detailed analysis, categorization, scoring, frustration analysis, and generate a roadmap. The categorization should be based on keyword matching, semantic understanding of the issue description, and comment analysis. The content of the issue bodies and comments should not be included in the output, aside from the metadata used for categorization.

Final Engagement Score Formula
Use the following formula to calculate the Engagement Score for each issue:

[
S = \frac{w_c \cdot C^{1.5} \cdot C_{penalty} \cdot w_d \cdot (D + 0.1) \cdot (1 + w_l \cdot A) \cdot (1 + w_u \cdot U)}{1 + w_a \cdot \sqrt{A + \epsilon}}
]
