Create a minimal working Hex example. An agent skill from jeremylongshore/tons-of-skills-marketplace.

  • Works in 5 steps: List Projects → Trigger a Project Run → Poll for Run Completion → …
  • Starting a new Hex integration
  • SKILL.md covers Overview, Prerequisites, Instructions and Output, plus 4 more sections
  • Calls curl and python3; needs HEX_API_TOKEN

What it does

Hex Hello World is an agent skill from jeremylongshore/tons-of-skills-marketplace. Create a minimal working Hex example. Use when starting a new Hex integration, testing your setup, or learning basic Hex API patterns. Trigger with phrases like "hex hello world", "hex example", "hex quick start", "simple hex code".

Its SKILL.md is about 1.1k 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 Testing & QA, covering 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 Hex integration
  • Testing your setup
  • Learning basic Hex API patterns
  • With phrases like hex hello world

Example prompts

  • “hex hello world”
  • “hex example”
  • “hex quick start”
  • “/hex-hello-world”

Requirements

  • Python 3
  • A credential in HEX_API_TOKEN
  • Compatibility (from SKILL.md): Designed for Claude Code
  • Pre-approved tools (allowed-tools): Read, Write, Edit, Bash(npm:*), Bash(curl:*)

Workflow steps

5 steps, taken from the step headings in SKILL.md.

  1. List Projects
  2. Trigger a Project Run
  3. Poll for Run Completion
  4. Complete Flow
  5. curl Quick Test

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:

    • Read
    • Write
    • Edit
    • Bash(npm:*)
    • Bash(curl:*)

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • curl
    • python3

    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):

    • learn.hex.tech

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • HEX_API_TOKEN

    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

Hex Hello World loads about 1.1k tokens when it runs. Until then it costs about 62 tokens; SKILL.md has 165 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~62
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k

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.

Hex Hello World

Overview

List projects, trigger a project run, and poll for results using the Hex API. The core workflow is: trigger a run of a published project, poll for completion, then access the results.

Prerequisites

  • Completed hex-install-auth setup
  • At least one published Hex project

Instructions

Step 1: List Projects
typescript
// hello-hex.ts
import 'dotenv/config';

const TOKEN = process.env.HEX_API_TOKEN!;
const BASE = 'https://app.hex.tech/api/v1';

async function listProjects() {
  const response = await fetch(`${BASE}/projects`, {
    headers: { 'Authorization': `Bearer ${TOKEN}` },
  });
  const projects = await response.json();
  for (const p of projects) {
    console.log(`${p.name} (${p.projectId}) — ${p.status}`);
  }
  return projects;
}
Step 2: Trigger a Project Run
typescript
async function runProject(projectId: string, inputParams?: Record<string, any>) {
  const response = await fetch(`${BASE}/project/${projectId}/run`, {
    method: 'POST',
    headers: { 'Authorization': `Bearer ${TOKEN}`, 'Content-Type': 'application/json' },
    body: JSON.stringify({
      inputParams: inputParams || {},
      updateCacheResult: true,
    }),
  });
  const { runId, projectId: pid, runStatusUrl } = await response.json();
  console.log(`Run started: ${runId}`);
  console.log(`Status URL: ${runStatusUrl}`);
  return { runId, projectId: pid, runStatusUrl };
}
Step 3: Poll for Run Completion
typescript
async function waitForRun(projectId: string, runId: string, timeoutMs = 300000): Promise<any> {
  const startTime = Date.now();
  while (Date.now() - startTime < timeoutMs) {
    const response = await fetch(`${BASE}/project/${projectId}/run/${runId}`, {
      headers: { 'Authorization': `Bearer ${TOKEN}` },
    });
    const status = await response.json();
    console.log(`Run ${runId}: ${status.status}`);

    if (status.status === 'COMPLETED') return status;
    if (status.status === 'ERRORED' || status.status === 'KILLED') {
      throw new Error(`Run failed: ${status.status}`);
    }

    await new Promise(r => setTimeout(r, 5000)); // Poll every 5s
  }
  throw new Error('Run timed out');
}
Step 4: Complete Flow
typescript
async function main() {
  const projects = await listProjects();
  if (projects.length === 0) { console.log('No projects found'); return; }

  const project = projects[0];
  const { runId } = await runProject(project.projectId, { date: '2025-01-01' });
  const result = await waitForRun(project.projectId, runId);
  console.log('Run completed:', result);
}

main().catch(console.error);
Step 5: curl Quick Test
bash
# List projects
curl -s -H "Authorization: Bearer $HEX_API_TOKEN" \
  https://app.hex.tech/api/v1/projects | python3 -m json.tool

# Trigger a run
curl -X POST -H "Authorization: Bearer $HEX_API_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"inputParams": {}}' \
  https://app.hex.tech/api/v1/project/PROJECT_ID/run | python3 -m json.tool

Output

  • Listed workspace projects with IDs and status
  • Triggered project run with optional input parameters
  • Polled run status until completion

Error Handling

ErrorCauseSolution
401Invalid tokenRegenerate API token
403Read-only tokenCreate token with "Run projects" scope
404Project not foundVerify project ID, ensure it's published

Examples

Run a sandbox project with fictional parameters and record project=proj-hello-1; params=test-only; run=complete; result=aggregate-pass; output_retention=none; cleanup=complete without retaining data output.
