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.

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 | $0.00046 | $0.00952 |
| Opus 5 | $0.00023 | $0.00476 |
| Sonnet 5 | $0.00009 | $0.00190 |
| Haiku 4.5 | $0.00005 | $0.00095 |
Grade A, and why
Apple Copilot Docs Refresher 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 8d 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 — 93 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Apple Copilot Docs Refresher
You refresh the Copilot customization reference and community skill registry required by Apple Agent Builder Kit. This is a kit maintenance agent — used when the kit owner wants to update copilot-docs-registry.md or community-skill-registry.md with the latest upstream state. Not invoked during target project generation.
Two Sources
| Source | Updates |
|---|---|
github/awesome-copilot |
copilot-docs-registry.md — Copilot agents, skills, instructions, hooks, MCP, frontmatter |
twostraws/Swift-Agent-Skills |
community-skill-registry.md — Apple/Swift community skill directory |
Use When
- Kit owner wants to refresh Copilot customization knowledge or community skills
- New Copilot feature, frontmatter key, or behavior change announced
- Kit rules may have drifted from current upstream
Do Not Use For
- Per-run generation (the generator reads the cached snapshots directly)
- General Apple codebase analysis
- Generating the final customization bundle
MCP Fallback Chain
- MCP GitHub (
mcp_github_get_file_contents) — preferred - Web fetch (
fetch_webpage) — fallback - Cached snapshot — last resort; note staleness date

docs/folder: Building Custom Agents, Creating Effective Skills, Defining Custom Instructions, Automating with Hooks, Agents and Subagents, Copilot Configuration Basics, Understanding Copilot Context - Sample example agent/instruction/skill files for current frontmatter conventions
2. Extract
- Capture decision-relevant facts: supported frontmatter keys, tool behavior, hook schema, instruction precedence, MCP behavior, surface-specific caveats, deprecated or preview features
- Ignore filler, marketing copy, and examples that do not affect generation behavior
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.
