validate-agent-files is a skill for Claude Code, Codex from JBurlison/WoWAddonAPIAgents. It costs 67 tokens per session (1,489 once invoked), scanned A, original, MIT.

A reference guide to World of Warcraft Retail APIs for mounts, pets, pet battles, toys, hunter stables, and heirlooms. These APIs let an addon read and manage a player’s collected game items and related systems.

In plain words
What is it for?
Use it when working on addon features for browsing, filtering, favoriting, summoning, or managing mounts, pets, toys, stable pets, and heirlooms.
Why use it?
It puts the relevant collection API functions and their purposes in one place. This reduces the need to search through general game API documentation while building an addon.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

validate-agent-files scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Validate Agent Files

Validates that agent, skill, prompt, and instruction files follow the correct format and structure.

Provider Folder Reference

This skill works across multiple AI coding assistant providers:

Provider Base Folder
GitHub Copilot .github/
Claude Code .claude/
Codex .codex/
OpenCode .config/opencode/

Throughout this document, <provider>/ represents your chosen provider's base folder.

When to Use

  • Before committing new agents, skills, prompts, or instructions
  • When an agent isn't behaving as expected
  • To audit existing customization files for issues
  • After modifying any .github customization files

Validation Process

Step 1: Identify File Type

Determine the type based on location and extension:

  • <provider>/agents/*.md → Agent file (user-invokable)
  • <provider>/agents/*.subagent.agent.md → Sub-agent file (workflow component)
  • <provider>/skills/*/SKILL.md → Skill file
  • <provider>/prompts/*.prompt.md → Prompt file
  • <provider>/instructions/*.instructions.md → Instruction file

Step 2: Apply Type-Specific Validation

Agent File Validation (<provider>/agents/*.md)

Required Structure:

---
name: agent-name
description: When to use this agent (should include examples)
user-invokable: true  # Optional, defaults to true
---

[System prompt body]

Supported Frontmatter Attributes:

  • name (required) - Agent identifier
  • description (required) - When/how to use, with examples
  • user-invokable (optional) - Set to false for sub-agents (default: true)
  • tools - List of allowed tools
  • model - Specific model to use
  • handoffs - Other agents this can delegate to

Checks:

  1. ✓ YAML frontmatter present with --- delimiters
  2. ✓ name field exists and is non-empty
  3. ✓ description field exists (recommend 50+ characters with examples)
  4. ✓ Body content exists after frontmatter
  5. ✓ If tools specified, they are valid tool names
  6. ✓ If filename contains .subagent.agent.md, verify user-invokable: false is set

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
