+## AI contributions in Spec Kit
+
+We welcome and encourage the use of AI tools to help improve Spec Kit! Many valuable contributions have been enhanced with AI assistance for code generation, issue detection, and feature definition.
+
+### What we're looking for
+
+When submitting AI-assisted contributions, please ensure they include:
+
+- **Human understanding and testing** - You've personally tested the changes and understand what they do
+- **Clear rationale** - You can explain why the change is needed and how it fits within Spec Kit's goals  
+- **Concrete evidence** - Include test cases, scenarios, or examples that demonstrate the improvement
+- **Your own analysis** - Share your thoughts on the end-to-end developer experience
+
+### What we'll close
+
+We reserve the right to close contributions that appear to be:
+
+- Untested changes submitted without verification
+- Generic suggestions that don't address specific Spec Kit needs
+- Bulk submissions that show no human review or understanding
+
+### Guidelines for success
+
+The key is demonstrating that you understand and have validated your proposed changes. If a maintainer can easily tell that a contribution was generated entirely by AI without human input or testing, it likely needs more work before submission.
+
+Contributors who consistently submit low-effort AI-generated changes may be restricted from further contributions at the maintainers' discretion.

+# Update agent context files with information from plan.md
+#
+# This script maintains AI agent context files by parsing feature specifications 
+# and updating agent-specific configuration files with project information.
+#
+# MAIN FUNCTIONS:
+# 1. Environment Validation
+#    - Verifies git repository structure and branch information
+#    - Checks for required plan.md files and templates
+#    - Validates file permissions and accessibility
+#
+# 2. Plan Data Extraction
+#    - Parses plan.md files to extract project metadata
+#    - Identifies language/version, frameworks, databases, and project types
+#    - Handles missing or incomplete specification data gracefully
+#
+# 3. Agent File Management
+#    - Creates new agent context files from templates when needed
+#    - Updates existing agent files with new project information
+#    - Preserves manual additions and custom configurations
+#    - Supports multiple AI agent formats and directory structures
+#
+# 4. Content Generation
+#    - Generates language-specific build/test commands
+#    - Creates appropriate project directory structures
+#    - Updates technology stacks and recent changes sections
+#    - Maintains consistent formatting and timestamps
+#
+# 5. Multi-Agent Support
+#    - Handles agent-specific file paths and naming conventions
+#    - Supports: Claude, Gemini, Copilot, Cursor, Qwen, opencode, Codex, Windsurf
+#    - Can update single agents or all existing agent files
+#    - Creates default Claude file if no agent files exist
+#
+# Usage: ./update-agent-context.sh [agent_type]
+# Agent types: claude|gemini|copilot|cursor|qwen|opencode|codex|windsurf
+# Leave empty to update all existing agent files

+.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, qwen, opencode, codex, windsurf)
+
+.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
