Use when encountering unfamiliar import statements, exploring dependency APIs, or when user asks "what's import X" or "what does X do". Generates on-demand API documentation for Swift package dependencies.

The file

We split this skill into the rules it gives an agent

3 rules. About 0 are common, 2 are distinctive, and 1 is very specific to this project.

  • ≈0

    Common · estimate

    Many files like this have a rule of this kind.

  • ≈2

    Distinctive · estimate

    This author's own choices. Worth a look.

  • 1

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  • Common
  • Distinctive
  • Very specific
  1. Very specific:

    When exploring unfamiliar dependencies, generate their documentation automatically instead of guessing from code.

    line 12
  2. Distinctive:

    When asked about an unfamiliar Swift module import:

    line 16
  3. Distinctive:

    Read the file and provide relevant information

    line 20

≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

Swift Package Documentation Generator

Generates API documentation for Swift package dependencies on-demand, extracting symbol information from Xcode's DerivedData to answer "what does this library do?"

Overview

When exploring unfamiliar dependencies, generate their documentation automatically instead of guessing from code. This tool uses interfazzle to extract symbol information from compiled modules.

How to Use

When asked about an unfamiliar Swift module import:

  1. Run: ./scripts/generate_docs.py "<module_name>" "<path_to.xcodeproj>"
  2. Script outputs path to cached documentation file
  3. Read the file and provide relevant information

Prerequisites: Project must be built once (DerivedData exists), interfazzle CLI installed.

See reference.md for error handling and details.

Does it work?

Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

No reviews yet

People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.

  • It worked
  • Partly
  • It didn't
What did you use it for? e.g. Reviewing pull requests in a Rails app

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.

Your trail

Files you open will collect here, so you can find them again.

Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.

Now do this for your own.

Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
