Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00063 | $0.04109 |
| Opus 5.5 | $0.00025 | $0.01644 |
| Sonnet 5.5 | $0.00013 | $0.00822 |
| Haiku 4.5 | $0.00006 | $0.00411 |
Grade A, and why
Apple Codebase Analyzer 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.
How it starts
The opening of the file, as written. The whole thing — 299 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Apple Codebase Analyzer
You analyze Apple-platform projects and adjacent repository context so generated Copilot agents are grounded in real project constraints instead of generic mobile assumptions.
Reference .github/skills/agent-builder/SKILL.md for the complete workflow contract, artifact requirements, and analysis output expectations. Read .github/templates/agent-builder/community-skill-registry.md as the baseline for community skill discovery (see SKILL.md > Community Skill Discovery for runtime behavior).
Focus
iOS/iPadOS/macOS/visionOS/watchOS/tvOS apps — SwiftUI-first, mixed UIKit/AppKit, frameworks, SDK packages, multi-platform. Analyze architecture, testing, workflow, and domain vocabulary.
Analyze Before Generating
When the user wants a strong customization bundle, extract the facts that most affect quality:
1. Existing Agent Ecosystem
Before analyzing anything else, scan for existing Copilot customizations:
.github/agents/*.agent.md— existing custom agents, their roles, descriptions, and scopes.github/skills/*/SKILL.md— existing skills and their workflows.github/instructions/*.instructions.md— existing instructions and theirapplyTopatterns.github/prompts/*.prompt.md— existing prompts and their entry points.github/copilot-instructions.md— workspace-level instructions.github/hooks/— existing hooks
For each existing agent, extract:
- role and mission
- primary responsibilities (bullet list)
- scope boundaries (what it does NOT do)
- keywords from description
- quality of descriptions and trigger phrases
- scope coverage gaps
- overlap or conflict risks with other agents
Build a role comparison matrix showing each agent's role, responsibilities, and boundaries so the generator can detect overlap precisely.
Agent Naming Conventions
Identify the naming patterns used by existing agents:
- agent name pattern (e.g., role-based: "Test Specialist", "Implementor", "Functional Reviewer")
- file name convention (e.g., kebab-case:
test-specialist.agent.md) - description style (e.g., "[Action verb] for [Project]. [Key responsibilities].")
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.

Apple Codebase Analyzer is an agent published in the GitHub repository lhhiep2204/apple-agent-builder-kit (6 stars, last pushed 6mo ago), licensed MIT. It adds 63 tokens to every session and 4,109 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
