In plain words
What is it for?
Add or improve documentation comments for Swift types and methods, including code examples and descriptions of inputs, outputs, and thrown errors.
Why use it?
It helps documentation follow DocC's expected format and avoids putting catalog-only headings in source comments.

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

swift-docc-comments 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 9d 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.

Swift DocC Inline Comments

Overview

Swift DocC inline comments follow a specific structure. Section headers like ## Overview and ## Topics belong in .docc catalog files, NOT in inline source comments.

Structure

/// Summary (first paragraph - one sentence)
///
/// Discussion paragraphs (no header needed)
///
/// ```swift
/// // Code example
/// ```
///
/// - Parameter name: Description
/// - Returns: Description
/// - Throws: Description
/// - Note: Additional info

Quick Reference

Element Format Location
Summary First paragraph Inline
Discussion Subsequent paragraphs Inline
Code examples Triple backticks Inline, before parameters
## Overview Section header .docc catalog ONLY
## Topics Section header .docc catalog ONLY
Symbol links ``SymbolName`` Both

Correct Format

/// Brief summary in one sentence.
///
/// Extended discussion explaining behavior, use cases,
/// or important details. No header needed.
///
/// ```swift
/// let example = MyType()
/// example.doSomething()
/// ```
///
/// - Parameter value: What this parameter does.
/// - Returns: What gets returned.
/// - Note: Default value is `.default`.
func method(value: Int) -> String

Common Mistakes

Wrong Correct
/// ## Overview Just write paragraphs
/// ## Topics Use .docc catalog file
/// ## Example Just use code block
Parameters before code Code block, then parameters

Red Flags

These indicate wrong format:

  • ## Overview in /// comments
  • ## Topics in /// comments
  • ## Example before code blocks
  • - Parameter: appearing before code examples

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.
