What it does
HTML Mockup Builder is an agent skill from zapier/gtm-cheat-codes, published by the product's own GitHub organization. Build self-contained HTML mockups from campaign, product, or page briefs.
Its SKILL.md is about 250 tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files (for example `ONBOARDING-PROMPT.md`, `README.md` and `SCHEMA-MAP.md`).
It sits in Productivity & Automation, covering Workflow automation. It works with Zapier. The repository describes itself as: A field guide for go to market teams using coding agents. Installable skills for campaign planning, CRM context, customer proof, and reviewable agent workflows. The licence is MIT.
When your agent uses it
- Tasks that involve Workflow automation
Example prompts
- “/html-mockup-builder”
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Identify page type, audience, and conversion goal.
- Determine required sections and content hierarchy.
- Build a self-contained HTML file with embedded CSS.
- Use the team's design system tokens and component patterns.
- Verify responsive behavior before sharing.
What it can do on your machine
Read from SKILL.md and the folder at commit 022a288. 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
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
HTML Mockup Builder loads about 245 tokens when it runs. Until then it costs about 23 tokens; SKILL.md has 129 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.
