AppBootstrapAI: Skill for Claude Code

.claude/skills/swift-docc-pro/SKILL.md

swift-docc-pro is a skill for Claude Code from kelvinkosbab/AppBootstrapAI. It costs 35 tokens per session (772 once invoked), scanned A, original, MIT.

A review guide for Swift documentation comments written in DocC, Apple’s system for generating documentation from source code. It checks public API descriptions, links, parameters, errors, and code examples.

In plain words
What is it for?
Use it to review documentation in Swift packages, check public declarations, validate parameter and return descriptions, and improve topic organization.
Why use it?
It helps catch missing or inaccurate documentation before readers rely on it. It also prevents DocC formatting and linking problems.

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-pro 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.

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.

Review Swift documentation comments for completeness, accuracy, and DocC compatibility. Report only genuine problems - do not nitpick or invent issues.

Review process:

  1. Verify all public declarations have documentation comments using references/comment-syntax.md.
  2. Validate parameter, return, and throws documentation completeness using references/comment-syntax.md.
  3. Check symbol linking syntax (Type) using references/symbol-linking.md.
  4. Validate code example formatting using references/code-examples.md.
  5. Suggest ## Topics organization for types with many members using references/topics.md.

If doing a partial review, load only the relevant reference files.

Core Instructions

  • All public declarations should have at least a one-line summary comment.
  • Use triple-slash /// for declaration documentation, not /** */ block comments.
  • Parameter, return, and throws documentation must match the actual signature exactly.
  • Code examples in doc comments should be valid, compilable Swift.
  • Use double-backtick symbol references (MyType) so DocC creates clickable links.
  • Markdown links to external documentation are encouraged — link to Apple's docs whenever referencing system APIs.
  • Don't repeat the obvious — public init() doesn't need "Initializes the type." Add docs only when they convey useful information.

Output Format

Organize findings by file. For each issue:

  1. State the file and relevant line(s).
  2. Name the rule being violated.
  3. Show a brief before/after code fix.

Skip files with no issues. End with a prioritized summary of the most impactful changes to make first.

Example output:

Sources/Retry/Retry.swift

Line 23: Missing - Throws: documentation for throwing function.

// Before
/// Retries an async operation with the configured strategy.
/// - Parameter operation: The async work to retry.
/// - Returns: The successful result of the operation.
public func retry<T>(
    _ operation: () async throws -> T
) async throws -> T

// After
/// Retries an async operation with the configured strategy.
/// - Parameter operation: The async work to retry.
/// - Returns: The successful result of the operation.
/// - Throws: The last error thrown by `operation` if all retry attempts are exhausted.
public func retry<T>(
    _ operation: () async throws -> T
) async throws -> T

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.
