What it does
Implementation Guide is an agent skill from gustavscirulis/snapgrid. Generates detailed implementation guide with pseudo-code and step-by-step development instructions. Creates IMPLEMENTATIONGUIDE.md from PRD, Architecture, and UX specs. Use when creating development roadmap.
Its SKILL.md is about 14k 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 Product & Project Management, covering iOS development and PRD writing. It works with iOS, Xcode 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
- Creating development roadmap
- Tasks that involve iOS development
- Tasks that involve PRD writing
Example prompts
- “Use the implementation-guide skill to generate detailed implementation guide with pseudo-code and step-by-step development instructions”
- “/implementation-guide”
Requirements
- Pre-approved tools (allowed-tools): Read, Write, Glob, Grep, AskUserQuestion
Workflow steps
6 steps, taken from the step headings in SKILL.md.
- Project Setup
- File Structure
- Implementation Phases
- Testing Implementation
- App Store Submission
- Troubleshooting Guide
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:
ReadWriteGlobGrepAskUserQuestion
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 and markdown).
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:
github.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
Implementation Guide loads about 14k tokens when it runs. Until then it costs about 57 tokens; SKILL.md has 1,327 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 1,327 words (~13,639 tokens).
“Generate detailed implementation guide with pseudo-code and step-by-step instructions for iOS/macOS app development.”
