+.SYNOPSIS
+Update agent context files with information from plan.md (PowerShell version)
+
+.DESCRIPTION
+Mirrors the behavior of scripts/bash/update-agent-context.sh:
+ 1. Environment Validation
+ 2. Plan Data Extraction
+ 3. Agent File Management (create from template or update existing)
+ 4. Content Generation (technology stack, recent changes, timestamp)
+ 5. Multi-Agent Support (claude, gemini, copilot, cursor-agent, qwen, opencode, codex, windsurf, junie, kilocode, auggie, roo, codebuddy, amp, shai, tabnine, kiro-cli, agy, bob, vibe, qodercli, kimi, trae, pi, iflow, forge, goose, generic)
+
+.PARAMETER AgentType
+Optional agent key to update a single agent. If omitted, updates all existing agent files (creating a default Claude file if none exist).
+
+.EXAMPLE
+./update-agent-context.ps1 -AgentType claude
+
+.EXAMPLE
+./update-agent-context.ps1   # Updates all existing agent files
+
+.NOTES
+Relies on common helper functions in common.ps1
