What is sf-symbol-mcp AGENTS.md?

A set of instructions for choosing Apple SF Symbols, which are built-in icons used in Apple-platform apps. It requires checking symbol names before using them in Swift code and validating them afterward.

Use it when selecting, checking, or validating SF Symbols for iOS or other Apple-platform user interfaces.

It helps prevent invalid icon names and unsuitable symbols from being added to an Apple app.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00160	$0.00160
Opus 5	$0.00080	$0.00080
Sonnet 5	$0.00032	$0.00032
Haiku 4.5	$0.00016	$0.00016

Security

Grade A, and why

sf-symbol-mcp AGENTS.md 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 10d 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.

What it actually says

SF Symbols Rules

When choosing icons for Apple platform UI:

Do not invent SF Symbol names.
Always call the sf-symbols MCP server before using Image(systemName:) or UIImage(systemName:).
Use search_symbols when looking for an icon by meaning.
Use get_symbol before committing a specific symbol name.
Use validate_symbols after editing Swift files that contain SF Symbols.
Prefer subtle, native, semantic symbols over overly literal symbols.
Do not use SF Symbols for App Store icons, launcher icons, logos, brand marks, or trademark-like usage.
If a symbol is unavailable on the target OS version, choose an older compatible symbol or ask whether to raise the deployment target.

Changes

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.
