Fetches Apple documentation as Markdown via Sosumi. An agent skill from CamilleScholtz/swmpc.
- Works in 3 steps: If you already have a… → If you do not know the exact page path,… → Prefer specific symbol pages instead of…

What it does
Sosumi is an agent skill from CamilleScholtz/swmpc. Fetches Apple documentation as Markdown via Sosumi. Use for Apple API reference, Human Interface Guidelines, WWDC transcripts, and external Swift-DocC pages.
Its SKILL.md is about 930 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Mobile, covering iOS development. The repository describes itself as: An MPD client for macOS & iOS.
When your agent uses it
- Apple API reference
- Human Interface Guidelines
- WWDC transcripts
- External Swift-DocC pages
Example prompts
- “Use the sosumi skill to fetch Apple documentation as Markdown via Sosumi. An agent skill from CamilleScholtz/swmpc”
- “/sosumi”
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- If you already have a developer.apple.com URL, replace the host with sosumi.ai and keep the same path.
- If you do not know the exact page path, search first, then fetch the best match.
- Prefer specific symbol pages instead of broad top-level pages when answering implementation questions.
What it can do on your machine
Read from SKILL.md and the folder at commit 51fa7cb. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
sosumi.aideveloper.apple.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Sosumi loads about 930 tokens when it runs. Until then it costs about 41 tokens; SKILL.md has 352 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (EUPL-1.2) doesn't allow us to republish the file, so here is its outline and opening line. It has 352 words (~930 tokens).
“Use this skill to reliably fetch Apple docs as Markdown when coding agents need precise API details.”
