What it does
Referral System is an agent skill from gustavscirulis/snapgrid. Generates referral/invite infrastructure with unique codes, deep link sharing, reward tracking, and fraud prevention. Use when user wants referral codes, invite friends flow, or viral growth mechanics.
Its SKILL.md is about 2.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `templates.md`).
It sits in Mobile. 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
- User wants referral codes
- Invite friends flow
- Viral growth mechanics
Example prompts
- “Use the referral-system skill to generate referral/invite infrastructure with unique codes, deep link sharing, reward tracking, and fraud prevention”
- “/referral-system”
Requirements
- Pre-approved tools (allowed-tools): Read, Write, Edit, Glob, Grep, Bash, AskUserQuestion
Workflow steps
8 steps, taken from the step headings in SKILL.md.
- Project Context Detection
- Conflict Detection
- Deep Link Setup Detection
- Read Templates
- Create Core Files
- Create UI Files
- Create Integration Files
- Determine File Location
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:
ReadWriteEditGlobGrepBashAskUserQuestion
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 swift).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
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
Referral System loads about 2.3k tokens when it runs. Until then it costs about 54 tokens; SKILL.md has 630 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: notes
The automated check noted patterns worth knowing about, such as sudo or a known installer.
- NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
allowed-tools: Read, Write, Edit, Glob, Grep, Bash, AskUserQuestion
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 630 words (~2,313 tokens).
“Generate a production referral/invite system with unique code generation, deep link sharing, reward tracking, fraud prevention, and SwiftUI views for inviting friends and monitoring referral performance.”
