What it does

Product Agent is an agent skill from gustavscirulis/snapgrid. Discover and validate product ideas, analyze markets, scope MVPs, and optimize app store presence for iOS/macOS apps.

It sits in Marketing & SEO, covering App store release, Market research and Startup and business strategy. It works with iOS and macOS. 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

They mention product agent

Example prompts

“product agent”
“app idea validation”

“/product-agent”

Requirements

A credential in ANTHROPIC_API_KEY
Pre-approved tools (allowed-tools): Bash(product-agent:*), Read

Workflow steps

9 steps, taken from the step headings in SKILL.md.

Quick Idea Validation
Deep Market Analysis
Save for Later
Compare Multiple Ideas

Read the Recommendation Carefully

Use Verbose Mode for Debugging

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:
- Bash(product-agent:*)
- Read
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 bash and json).
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 these keys or tokens, usually read from environment variables:
- ANTHROPIC_API_KEY
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Product Agent loads about 2.6k tokens when it runs. Until then it costs about 89 tokens; SKILL.md has 1,014 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~89
When it runs · the whole SKILL.md, loaded when a task matches: ~2.6k

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 1,014 words (~2,592 tokens).

“Product Agent is an AI-powered CLI tool for iOS/macOS app product development. It uses specialized agents to guide you from idea to launch.”
