Simplify repo-consistency agent instructions

[Copilot]

The repo-consistency agent was excessively verbose, burying the actionable steps in walls of redundant explanation. Strips it down to only what matters, and ensures the agent has the tools and precision needed to operate successfully.

Description

Rewrote .github/agents/repo-consistency.agent.md to be concise and actionable:

• Removed 8 sections: "When to Invoke This Agent", "Primary Responsibilities", "Template Evolution Intelligence", "Quality Gate Verification", "Cross-Agent Coordination", "Template Reference Integration", "Usage Pattern Framework", "Compliance Verification Checklist"
• Added "Consistency Steps" — a 3-step numbered list replacing ~250 lines of prose:
  1. Fetch the last 20 merged PRs (is:pr is:merged) from https://github.com/demaconsulting/TemplateDotNetLibrary
  2. Determine intent of each PR (what changes were performed to which files)
  3. Apply missing changes to this repository's files (where appropriate, with translation)
• Kept "Reporting", "Don't Do These Things", and "Key Principles"
• Updated tools in YAML frontmatter from [read, search, github] to [edit, read, search, github, agent]:
  • Added edit — required by step 3 to apply file changes directly in the downstream repository
  • Added agent — available for coordination with specialized agents where needed
• Improved step 1 precision: uses explicit repository URL and GitHub search qualifiers (is:pr is:merged) so the agent can unambiguously locate and filter merged template PRs
• Removed from "Don't Do These Things": Never modify downstream code directly — the agent applies changes itself
• Removed from "Key Principles": Evidence-Based Recommendations and Cross-Agent Coordination — the agent performs changes directly rather than delegating

File reduced from 297 → 40 lines.

@copilot I would like you to review this repo-consistency agent and determine if you think there's anything missing or which could be specified more precisely to ensure it operates successfully. For example is it more likely it would be able to find the TemplateDotNetLibrary repository if it used a web-link such as https://github.com/demaconsulting/TemplateDotNetLibrary

Two improvements made in 12bbb8b:

Step 1 precision: Changed "completed" → "merged" (the correct GitHub term) and added the explicit URL https://github.com/demaconsulting/TemplateDotNetLibrary so the agent can unambiguously locate the repository.

Tools: The original [read, search, github] was missing two tools needed for the agent to operate end-to-end:

• edit — required by step 3 ("Apply missing changes to this repository's files")
• agent — required to invoke specialized agents for implementation (as called for by "Cross-Agent Coordination" in Key Principles and "coordinate through appropriate specialized agents" in Don't Do These Things)

Updated frontmatter: tools: [edit, read, search, github, agent]

The current file looks well-specified for reliable operation. Key precision improvements already applied: explicit URL https://github.com/demaconsulting/TemplateDotNetLibrary (57af28f also adds is:pr is:merged qualifiers so the GitHub API call is unambiguous), "merged" rather than "completed", edit tool in frontmatter so the agent can actually apply changes, and cleaned-up guardrails that no longer contradict the agent's direct-action mandate.
