Walkthrough

Two GitHub Actions workflows handle discussion processing: a new deduplication workflow identifies duplicate discussions via Claude with an 80% similarity threshold and posts comments linking to originals, while the existing triage workflow is refactored to process discussions instead of issues, incorporating a pre-check for duplicates and conditional execution based on label status.

Changes

Cohort / File(s)	Summary
New Discussion Deduplication Workflow \\.github/workflows/discussion-deduplication.yml	New workflow triggered on discussion creation or manual dispatch. Configures MCP server, invokes Claude Code to search for duplicate discussions using gh CLI and GraphQL, applies 80% similarity threshold, posts comments with links to original discussions, and adds duplicate labels via GraphQL.
Modified Discussion Triage Workflow \\.github/workflows/triage.yml	Transformed from issue-based to discussion-based workflow. Added pre-check step for duplicate labels using GraphQL. Conditional execution: subsequent steps (checkout, MCP setup, Claude triage) only run if no duplicate label present. Updated MCP image tag to v0.26.3, revised prompts to reference discussion-specific tools, and deferred duplicate labeling to separate workflow.

Poem

🐰 Hops with glee ✨

Discussions now deduplicated with care,
Claude sniffs out copies floating in air,
Triage flows smooth with pre-checks so keen,
No more duplicate chaos—clarity's seen! 🎯
