SDL3 Documentation Skill

You have access to the complete SDL3 wiki (4,890 API docs). Use progressive disclosure — start narrow, expand only as needed.

Lookup strategy (follow in order)

1. Specific function/type query → direct lookup

If the user asks about a known symbol (e.g. SDL_CreateWindow, IMG_Load):

  1. Read lookup.md (in this skill directory) — find the symbol's category and one-line description
  2. Read the full doc: docs/SDL3/<SymbolName>.md (or docs/SDL3_image/, SDL3_mixer/, etc.)
  3. Present: signature, parameters, return value, key remarks, code example if available, see-also links

2. Topic/domain query → category drill-down

If the user asks about a topic (e.g. "how does audio work", "window management"):

  1. Read index.md (in this skill directory) — find the matching category and its file path
  2. Read the category file (e.g. docs/SDL3/CategoryAudio.md) — get the overview + full symbol list
  3. Summarize the category, highlight the most relevant functions
  4. Only read individual function docs if the user wants specifics

3. Fuzzy/unknown query → search

If you can't find it in lookup.md or index.md:

  1. Grep for the term across docs/ — check function names, descriptions
  2. Glob for docs/SDL3/*<term>*.md to find matching files
  3. Read the best match

Response guidelines

  • Lead with the function signature in a C code block
  • Include parameter table and return value
  • Mention thread safety and version if relevant
  • Include code examples when available — these are high value
  • Link to related functions the user likely needs next
  • For broad topics, give an overview with the 3-5 most important functions before listing everything

概要と使いどころ

altirra-bridge

無料

Use this skill when controlling the AltirraSDL Atari emulator programmatically — driving the simulator from a script, capturing screenshots from a running Atari, injecting joystick/keyboard input, frame-stepping for deterministic testing, reading or writing CPU/memory/chip state, setting breakpoints or watchpoints, profiling 6502 code, loading symbols, or building automated tests against an Atari binary. Triggers on phrases like "AltirraBridge", "AltirraSDL --bridge", "AltirraBridgeServer", "Altirra Python SDK", "headless Atari emulator", "screenshot the Atari", "automate AltirraSDL", "drive the emulator from Python", "Atari debugger over a socket", "altirra_bridge package", as well as on tasks involving the bridge protocol, the Python `altirra_bridge` package, or the C `altirra_bridge.h` SDK.
