A way to read and update Webflow CMS collections, which are structured content lists such as blog posts, FAQs, and pages. It covers finding a site, authenticating with the Webflow API, changing collection items, and publishing updates.

Use it to query, create, update, or publish Webflow CMS content such as FAQs, pages, blog posts, and other collection items.

It avoids editing every CMS item manually in Webflow when content needs to be inspected or changed through code.

webflow-cms — Skill for Claude Code and Codex by S3YED

Install

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.

Any agent

npx skills add S3YED/appie-kit --skill webflow-cms

Clone the repo

git clone --depth 1 https://github.com/S3YED/appie-kit

Made for: Claude Code, Codex.

Token cost

What it costs to keep this loaded

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	$0.00042	$0.01215
Opus 5	$0.00021	$0.00607
Sonnet 5	$0.00008	$0.00243
Haiku 4.5	$0.00004	$0.00121

Security

Grade A, and why

webflow-cms scanned grade A with 1 finding 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 9d 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.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Webflow CMS Operations

Use when working with Webflow CMS collections: reading/updating FAQs, pages, blog posts, or any CMS-driven content. NOT for site structure/design changes (use the Webflow Designer for that).

Setup

Authentication

Webflow API v2 uses a Site Access Token (site-scoped) or a Personal Access Token (account-scoped).

export WEBFLOW_API_TOKEN="your_token_here"

Store tokens in ~/.hermes/.env or ~/clawd/.env.secrets:

WEBFLOW_SITENAME_TOKEN=xxx

Convention: WEBFLOW_{PROJECT_NAME}_TOKEN in all-caps with underscores.

Finding the Site ID

Every Webflow site has a unique ID embedded in the live HTML:

document.querySelector('[data-wf-site]')?.getAttribute('data-wf-site')

Run this in the browser console on the live site, or look for it in the page source (<html data-wf-site="...">).

Discovery Flow

When you don't know the site ID or token:

Open the live site in a browser
Extract site ID from <html data-wf-site="..."> via browser console
Search credentials in:
- ~/.hermes/.env — Hermes env vars
- ~/clawd/.env.secrets — project secrets
- 1Password vault (via op CLI)
- Notion project pages (search for "Webflow" or "token")
If no token found → ask the user or client

Common Operations

All examples use the Webflow API v2 at https://api.webflow.com/v2/.

List all collections for a site

curl -s "https://api.webflow.com/v2/sites/${SITE_ID}/collections" \
  -H "Authorization: Bearer ${WEBFLOW_API_TOKEN}"

Get collection items

curl -s "https://api.webflow.com/v2/collections/${COLLECTION_ID}/items?limit=100" \
  -H "Authorization: Bearer ${WEBFLOW_API_TOKEN}"

Get a specific item

curl -s "https://api.webflow.com/v2/collections/${COLLECTION_ID}/items/${ITEM_ID}" \
  -H "Authorization: Bearer ${WEBFLOW_API_TOKEN}"

Update a CMS item (PATCH)

curl -s -X PATCH "https://api.webflow.com/v2/collections/${COLLECTION_ID}/items/${ITEM_ID}" \
  -H "Authorization: Bearer ${WEBFLOW_API_TOKEN}" \
  -H "Content-Type: application/json" \
  -d '{"fieldData": {"field-slug": "new value"}}'

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.
