Linear

Connects Claude to Linear's issue tracker with smart conventions baked in. It handles the full workflow: retrieves issues (including embedded screenshots you'd miss from markdown alone), updates status as you work, and crucially enforces the two-step close: magic keywords in the PR body for auto-linking plus a human-readable completion comment so your PM doesn't land on a closed issue with zero context. The sub-issue tree guidance is particularly opinionated, prefix numbering tasks since the MCP tools don't expose sort order, topological creation order to satisfy blockedBy dependencies, and per-issue completion to avoid the batch-update-at-the-end trap where things get forgotten. Treats Linear as a collaboration surface, not just a ticket system.
