Title

Add missing description fields to agents, instructions, and prompts to resolve workflow validation errors

Description

Several asset files are failing validation in the Sync and Publish workflow because they do not include the required description field in their YAML frontmatter, leading to exclusion from publication and release. Examples include agent files, instructions, and prompts.

Steps to Reproduce:

1. Run the Sync and Publish GitHub Actions workflow
2. Observe validation output (example log)
3. Notice errors, e.g.:
   • "Validation failed: Missing required field: description"
   • "View asset: https://github.com/archubbuck/workspace-architect/blob/main/assets/agents/declarative-agents-architect.agent.md"

Expected Behavior:

All agent, instruction, and prompt files should contain a description field in their frontmatter, and workflow validation should pass.

Actual Behavior:

Files without a description field are excluded, and the workflow fails.

Environment:

• OS: Ubuntu-latest (GitHub Actions runner)
• Workflow file: .github/workflows/sync-and-publish.yml
• Main languages: Python 77.9%, JavaScript 18.7%, HTML 2.2%, Shell 1.2%

Additional Context:

Example of a failing asset:

• declarative-agents-architect.agent.md (missing description)
• Multiple instructions and prompts in assets/instructions/ and assets/prompts/ show similar errors.

Code Reference:

Add to each asset frontmatter (top of file):

---
description: "Concise description of this agent/instruction/prompt."
---
