What it does
Privacy Manifests is an agent skill from gustavscirulis/snapgrid. Privacy manifest (PrivacyInfo.xcprivacy) implementation including required reason APIs, tracking domains, third-party SDK declarations, and App Tracking Transparency. Use when preparing apps for App Store privacy requirements.
Its SKILL.md is about 4.2k 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 App store release. It works with Xcode. The repository describes itself as: SnapGrid is an open-source Mac app for collecting, organizing, and analyzing UI screenshots. It uses AI to automatically detect UI components and patterns, making it a powerful…
When your agent uses it
- Preparing apps for App Store privacy requirements
- Tasks that involve App store release
Example prompts
- “/privacy-manifests”
Requirements
- Pre-approved tools (allowed-tools): Read, Glob, Grep
Workflow steps
2 steps, taken from the step headings in SKILL.md.
- Scan the Project
- Determine What Is Missing and Apply Fixes
What it can do on your machine
Read from SKILL.md and the folder at commit eb7eaf4. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
ReadGlobGrep
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are xml, bash and swift).
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:
apple.com
Also links to:
developer.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
Privacy Manifests loads about 4.2k tokens when it runs. Until then it costs about 61 tokens; SKILL.md has 1,560 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 (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,560 words (~4,204 tokens).
“Advisory skill for implementing Apple's privacy manifest requirements. Privacy manifests (PrivacyInfo.xcprivacy) became mandatory for App Store submissions in Spring 2024. This skill covers the manifest file format, required reason APIs, tracking declarations, third-party SDK privacy, and App Tracking Transparency.”
