Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00090 | $0.01015 |
| Opus 5 | $0.00045 | $0.00508 |
| Sonnet 5 | $0.00018 | $0.00203 |
| Haiku 4.5 | $0.00009 | $0.00102 |
Grade A, and why
webflow-designer-api scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 72 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Webflow Designer API
This skill helps users work with the Webflow Designer API through two workflows. Start by asking the user which workflow they'd like to use, or infer from context if it's obvious.
Workflows
1. Designer Extensions
Build full extensions with a UI that run inside the Webflow Designer as iframes. Best for reusable tools, complex workflows, and apps you want to ship to a team or the Marketplace. → See references/designer-extension-workflow.md
2. Designer API Playground
Write and run standalone code snippets directly in the Playground app inside the Designer. Best for quick prototyping, testing API methods, learning the API, and one-off automations. → See references/playground-workflow.md
Reference Documentation
Each reference file includes YAML frontmatter with name, description, and tags for searchability. Use the search script available in scripts/search_references.py to quickly find relevant references by tag or keyword.
Designer API References
Both workflows use the same webflow.* Designer API. Once you know the workflow, use these references to write the actual code:
- references/designer-apis-reference.md — All
webflow.*methods in one table (start here) - references/elements-api.md — Element selection, insertion, presets, and the element builder
- references/styles-api.md — Creating styles, setting CSS properties, breakpoints, and pseudo-states
- references/components-api.md — Component definitions, instances, and editing context
- references/pages-api.md — Page and folder management
- references/variables-api.md — Design token variables and collections
- references/assets-api.md — Asset upload and management
- references/extension-utilities.md — Site info, events, notifications, app discovery, authentication
- references/error-handling.md — Error structure, cause tags, and recovery patterns
- references/code-examples.md — Cross-API workflow examples combining multiple APIs
What ships with it
22 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

webflow-designer-api is a skill published in the GitHub repository 224-Industries/webflow-skills (9 stars, last pushed 27d ago), licensed MIT. It adds 90 tokens to every session and 1,015 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
