Use when starting a new Clay integration, testing webhook setup, or verifying that enrichment columns are working. Trigger with phrases like "clay hello world", "clay example", "clay quick start", "first clay enrichment", "test clay webhook".
Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts. Compatibility notes: Designed for Claude Code
It sits in Backend & APIs, covering Webhooks and Integration testing. The repository describes itself as: Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com. The licence is MIT.
When your agent uses it
- Starting a new Clay integration
- Testing webhook setup
- Verifying that enrichment columns are working
- With phrases like clay hello world
Example prompts
- “clay hello world”
- “clay example”
- “clay quick start”
- “/clay-hello-world”
Requirements
- Python 3

- Compatibility (from SKILL.md): Designed for Claude Code
- Pre-approved tools (allowed-tools): Read, Write, Edit, Bash(curl:*), Bash(node:*)
Workflow steps
5 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit cfae287. 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:
ReadWriteEditBash(curl:*)Bash(node:*)
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
curl
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
university.clay.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.
Compatibility
Designed for Claude Code
From compatibility in the SKILL.md frontmatter.
Context cost
Clay Hello World loads about 1.3k tokens when it runs. Until then it costs about 80 tokens; SKILL.md has 371 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.

Clay Hello World
Overview
Minimal working example: send a company domain to a Clay table via webhook, let Clay's enrichment columns fill in company data, and retrieve the enriched result. Clay does not have a traditional SDK — you interact with it via webhooks (data in), HTTP API columns (data out), and the web UI.
Prerequisites
- Completed
clay-install-authsetup - Clay workbook with a webhook source configured
- At least one enrichment column added to the table
Instructions
Step 1: Create a Clay Table with Enrichment
In the Clay web UI:
- Create a new workbook
- Add columns:
domain,company_name,employee_count,industry - Click + Add at bottom, select Webhooks > Monitor webhook
- Copy the webhook URL
- Add an enrichment column: + Add Column > Enrich Company (uses the
domaincolumn as input)
Step 2: Send Your First Record via Webhook
# Send a single company domain to your Clay table
curl -X POST "https://app.clay.com/api/v1/webhooks/YOUR_WEBHOOK_ID" \
-H "Content-Type: application/json" \
-d '{"domain": "openai.com"}'Within seconds, Clay creates a new row and auto-runs the enrichment column. The company_name, employee_count, and industry columns fill in automatically.
Step 3: Send Multiple Records
# Batch send — each object becomes a row
for domain in stripe.com notion.so figma.com linear.app; do
curl -s -X POST "https://app.clay.com/api/v1/webhooks/YOUR_WEBHOOK_ID" \
-H "Content-Type: application/json" \
-d "{\"domain\": \"$domain\"}"
echo " -> Sent $domain"
doneStep 4: Send from Node.js
// hello-clay.ts — send records to Clay via webhook
const CLAY_WEBHOOK_URL = process.env.CLAY_WEBHOOK_URL!;
interface LeadInput {
email?: string;
domain?: string;
first_name?: string;
last_name?: string;
linkedin_url?: string;
}
async function sendToClay(lead: LeadInput): Promise<Response> {
const response = await fetch(CLAY_WEBHOOK_URL, {
method: 'POST',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify(lead),
});
if (!response.ok) {
throw new Error(`Clay webhook failed: ${response.status} ${response.statusText}`);
}
return response;
}
// Send a test lead
await sendToClay({
email: 'jane@stripe.com',
first_name: 'Jane',
last_name: 'Doe',
domain: 'stripe.com',
});
console.log('Record sent to Clay — check your table for enriched data.');Step 5: Send from Python
import requests
import os
CLAY_WEBHOOK_URL = os.environ["CLAY_WEBHOOK_URL"]
def send_to_clay(lead: dict) -> requests.Response:
"""Send a lead record to a Clay table via webhook."""
response = requests.post(
CLAY_WEBHOOK_URL,
json=lead,
headers={"Content-Type": "application/json"},
)
response.raise_for_status()
return response
# Test it
send_to_clay({
"email": "jane@stripe.com",
"first_name": "Jane",
"last_name": "Doe",
"domain": "stripe.com",
})
print("Record sent to Clay — check your table for enriched data.")Error Handling
| Error | Cause | Solution |
|---|---|---|
404 Not Found | Invalid webhook URL | Re-copy URL from Clay table settings |
422 Unprocessable | Invalid JSON payload | Validate JSON structure before sending |
| Row appears but no enrichment | Enrichment column not configured | Add enrichment column in Clay UI, enable auto-run |
429 Too Many Requests | Exceeded webhook rate limit | Add 100ms delay between requests |
| Webhook limit reached (50K) | Webhook exhausted | Create a new webhook source on the table |
Show full SKILL.md (127 more words)Show less
Output
The first run confirms receipt of a controlled test row and returns only a redacted status/correlation value. A successful webhook acknowledgement does not confirm enrichment quality, lawful data use, or CRM publication; inspect the authorized staging table and configured conditions before taking the next step.
Examples
Send a synthetic or explicitly approved test record to a staging webhook, log the response status without the webhook URL or personal data, and verify that the resulting row is subject to the intended enrichment conditions. If the endpoint returns 4xx/5xx, stop instead of creating new webhooks or resending the record until the configuration is corrected.
