What it does

Hex Core Workflow A is an agent skill from jeremylongshore/tons-of-skills-marketplace. Execute Hex primary workflow: Core Workflow A. Use when implementing primary use case, building main features, or core integration tasks. Trigger with phrases like "hex main workflow", "primary task with hex".

Its SKILL.md is about 1.2k 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 Data & Analytics. 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

  • Implementing primary use case
  • Building main features
  • Core integration tasks
  • With phrases like hex main workflow

Example prompts

  • “hex main workflow”
  • “primary task with hex”
  • “/hex-core-workflow-a”

Requirements

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

Workflow steps

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

  1. Parameterized Project Runs
  2. Synchronous Run Helper
  3. Pipeline Orchestration
  4. Cancel Long-Running Projects

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:*)
    • Grep

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are typescript).

    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
    • 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 Core Workflow A loads about 1.2k tokens when it runs. Until then it costs about 57 tokens; SKILL.md has 196 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~57
When it runs · the whole SKILL.md, loaded when a task matches
~1.2k

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 Project Orchestration

Overview

Trigger Hex project runs from external orchestration tools (Airflow, Dagster, cron) with input parameters, status polling, and error handling. This is the primary integration pattern for embedding Hex in data pipelines.

Instructions

Step 1: Parameterized Project Runs
typescript
import 'dotenv/config';
const TOKEN = process.env.HEX_API_TOKEN!;
const BASE = 'https://app.hex.tech/api/v1';

interface RunConfig {
  projectId: string;
  inputParams?: Record<string, any>;
  updateCache?: boolean;
  killRunning?: boolean;
}

async function triggerRun(config: RunConfig) {
  const response = await fetch(`${BASE}/project/${config.projectId}/run`, {
    method: 'POST',
    headers: { 'Authorization': `Bearer ${TOKEN}`, 'Content-Type': 'application/json' },
    body: JSON.stringify({
      inputParams: config.inputParams || {},
      updateCacheResult: config.updateCache ?? true,
      killRunningExecution: config.killRunning ?? false,
    }),
  });
  if (!response.ok) throw new Error(`Trigger failed: ${response.status} ${await response.text()}`);
  return response.json();
}
Step 2: Synchronous Run Helper
typescript
async function runAndWait(config: RunConfig, timeoutMs = 600000): Promise<any> {
  const { runId, projectId } = await triggerRun(config);
  const startTime = Date.now();

  while (Date.now() - startTime < timeoutMs) {
    const res = await fetch(`${BASE}/project/${projectId}/run/${runId}`, {
      headers: { 'Authorization': `Bearer ${TOKEN}` },
    });
    const status = await res.json();

    switch (status.status) {
      case 'COMPLETED': return { success: true, runId, duration: Date.now() - startTime };
      case 'ERRORED': throw new Error(`Run ${runId} errored: ${status.statusMessage || 'unknown'}`);
      case 'KILLED': throw new Error(`Run ${runId} was killed`);
      default: await new Promise(r => setTimeout(r, 5000));
    }
  }
  throw new Error(`Run ${runId} timed out after ${timeoutMs}ms`);
}
Step 3: Pipeline Orchestration
typescript
// Run multiple Hex projects in sequence (data pipeline)
async function runPipeline(steps: RunConfig[]) {
  const results = [];
  for (const step of steps) {
    console.log(`Running: ${step.projectId}`);
    const result = await runAndWait(step);
    console.log(`Completed in ${result.duration}ms`);
    results.push(result);
  }
  return results;
}

// Example: ETL pipeline
await runPipeline([
  { projectId: 'extract-project-id', inputParams: { date: '2025-01-01' } },
  { projectId: 'transform-project-id' },
  { projectId: 'load-project-id', updateCache: true },
]);
Step 4: Cancel Long-Running Projects
typescript
async function cancelRun(projectId: string, runId: string) {
  const response = await fetch(`${BASE}/project/${projectId}/run/${runId}`, {
    method: 'DELETE',
    headers: { 'Authorization': `Bearer ${TOKEN}` },
  });
  console.log(`Cancelled run ${runId}: ${response.status}`);
}

Error Handling

ErrorCauseSolution
429 Too Many RequestsRate limit (20/min, 60/hr)Queue runs with delays
Run ERROREDProject code failedCheck project logs in Hex UI
Run KILLEDTimeout or manual cancelIncrease timeout or fix slow queries
404Project not publishedPublish project before triggering runs

Prerequisites

  • A named project owner, environment allowlist, approved parameter schema, and a sandbox project with fictitious or approved test data.
  • Execution/cancel authority scoped to one project, a correlation convention, and a rollback or cancel procedure.

Output

Return an orchestration receipt with opaque project/run IDs, parameter revision, trigger identity class, start/terminal state, aggregate assertions, cancellation result, and rollback reference. Do not store SQL, cell output, or credentials.

Examples

project=proj-sandbox-12; params=r3; trigger=ci-service; run=complete; assertions=pass; cancel=not-needed; rollback=run-r5 records a controlled project run.
