Add agent-assign extension to community catalog

[xymelon]

Summary

Adds the Agent Assign extension to the community catalog.

• Extension: spec-kit-agent-assign
• Category: process
• Effect: Read+Write
• Version: 1.0.0
• License: MIT

What it does

Routes spec-kit tasks to specialized Claude Code agents for targeted execution. Scans .claude/agents/ definitions, assigns each task to the best-fit agent, and executes via dedicated subagents — replacing the flat /speckit.implement with agent-aware, context-isolated execution.

Commands

Command	Description
speckit.agent-assign.assign	Scan available agents and assign them to tasks
speckit.agent-assign.validate	Validate that all assignments are correct
speckit.agent-assign.execute	Execute tasks with specialized agent spawning

Benchmark

Tested on TuneMuse with three frontier models. Agent-assign scored +6.7 points higher on average (23.2 vs 16.5 out of 30), a 40% improvement over standard spec-kit.

• The extensions entries in this file appear to be kept in lexicographic order by extension id (e.g., archive, azure-devops, checkpoint, ...). With agent-assign inserted after aide, the ordering is now inconsistent; consider moving agent-assign before aide to keep the catalog stable and reduce merge conflicts.
