What this skill does

# Together AI Webhooks & Events

## Overview

Together AI delivers webhook callbacks for asynchronous operations including fine-tuning jobs, batch inference, and model lifecycle events. Subscribe to events for fine-tune completion, job failures, model deprecation notices, and batch processing status to build automated ML pipelines without polling the jobs API.

## Webhook Registration

```typescript
const response = await fetch("https://api.together.xyz/v1/webhooks", {
  method: "POST",
  headers: {
    "Authorization": `Bearer ${process.env.TOGETHER_API_KEY}`,
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
    url: "https://yourapp.com/webhooks/together",
    events: ["fine_tune.completed", "fine_tune.failed", "model.deprecated", "batch.done"],
    secret: process.env.TOGETHER_WEBHOOK_SECRET,
  }),
});
```

## Signature Verification

```typescript
import crypto from "crypto";
import { Request, Response, NextFunction } from "express";

function verifyTogetherSignature(req: Request, res: Response, next: NextFunction) {
  const signature = req.headers["x-together-signature"] as string;
  const expected = crypto.createHmac("sha256", process.env.TOGETHER_WEBHOOK_SECRET!)
    .update(req.body).digest("hex");
  if (!crypto.timingSafeEqual(Buffer.from(signature), Buffer.from(expected))) {
    return res.status(401).json({ error: "Invalid signature" });
  }
  next();
}
```

## Event Handler

```typescript
import express from "express";
const app = express();

app.post("/webhooks/together", express.raw({ type: "application/json" }), verifyTogetherSignature, (req, res) => {
  const event = JSON.parse(req.body.toString());
  res.status(200).json({ received: true });

  switch (event.type) {
    case "fine_tune.completed":
      deployModel(event.data.fine_tune_id, event.data.model_name); break;
    case "fine_tune.failed":
      alertTeam(event.data.fine_tune_id, event.data.error_message); break;
    case "model.deprecated":
      migratePipelines(event.data.model_id, event.data.replacement_model); break;
    case "batch.done":
      collectResults(event.data.batch_id, event.data.output_url); break;
  }
});
```

## Event Types

| Event | Payload Fields | Use Case |
|-------|---------------|----------|
| `fine_tune.completed` | `fine_tune_id`, `model_name`, `eval_loss` | Auto-deploy fine-tuned model |
| `fine_tune.failed` | `fine_tune_id`, `error_message`, `step` | Alert team and retry with adjusted params |
| `model.deprecated` | `model_id`, `replacement_model`, `sunset_date` | Migrate inference pipelines proactively |
| `batch.done` | `batch_id`, `output_url`, `total_tokens` | Download batch results and update billing |
| `fine_tune.checkpoint` | `fine_tune_id`, `step`, `loss` | Monitor training progress in real time |

## Retry & Idempotency

```typescript
const processed = new Set<string>();

async function handleIdempotent(event: { id: string; type: string; data: any }) {
  if (processed.has(event.id)) return;
  await routeEvent(event);
  processed.add(event.id);
  if (processed.size > 10_000) {
    const entries = Array.from(processed);
    entries.slice(0, entries.length - 10_000).forEach((id) => processed.delete(id));
  }
}
```

## Error Handling

| Issue | Cause | Fix |
|-------|-------|-----|
| `401 Unauthorized` | Invalid or expired API key | Rotate key at api.together.xyz |
| Fine-tune stuck | Training data format issues | Validate JSONL before submission |
| Batch timeout | Large batch exceeds time limit | Split into smaller batches |
| Model not found | Deprecated without migration | Check `model.deprecated` events proactively |

jfrog

Included

Interact with the JFrog Platform via the JFrog CLI and REST/GraphQL APIs. Use this skill when the user wants to manage Artifactory repositories, upload or download artifacts, manage builds, configure permissions, manage users and groups, work with access tokens, configure JFrog CLI servers, search artifacts, manage properties, set up replication, manage JFrog Projects, run security audits or scans, look up CVE details, query exposures scan results from JFrog Advanced Security, manage release bundles and lifecycle operations, aggregate or export platform data, or perform any JFrog Platform administration task. Also use when the user mentions jf, jfrog, artifactory, xray, distribution, evidence, apptrust, onemodel, graphql, workers, mission control, curation, advanced security, exposures, or any JFrog product name.

cupynumeric-migration-readiness

Included

Pre-migration readiness assessor for porting NumPy to cuPyNumeric. Use BEFORE substantial porting work begins when the user asks whether code will scale on GPU, whether they should migrate to cuPyNumeric, which NumPy patterns transfer cleanly, what must be refactored before porting, or mentions pre-port assessment, scaling analysis, or refactor planning. Inspect the user's source code, look up NumPy usage, cross-reference the cuPyNumeric API support manifest, and distinguish distributed-scaling-friendly patterns from blockers such as unsupported APIs, scalar synchronization, host round-trips, Python/object-heavy control flow, shape/data-dependent branching, and in-place mutation hazards. Produce a verdict of READY, LIGHT REFACTOR, SIGNIFICANT REFACTOR, or NOT RECOMMENDED, with concrete refactor pointers.

alibabacloud-data-agent-skill

Included

Invoke Alibaba Cloud Apsara Data Agent for Analytics via CLI to perform natural language-driven data analysis on enterprise databases. Data Agent for Analytics is an intelligent data analysis agent developed by Alibaba Cloud Database team for enterprise users. It automatically completes requirement analysis, data understanding, analysis insights, and report generation based on natural language descriptions. This tool supports: discovering data resources (instances/databases/tables) managed in DMS, initiating query or deep analysis sessions, real-time progress tracking, and retrieving analysis conclusions and generated reports. Use this Skill when users need to query databases, analyze data trends, generate data reports, ask questions in natural language, or mention "Data Agent", "data analysis", "database query", "SQL analysis", "data insights".

Backend & APIsscripts

token-optimizer

Included

Reduce OpenClaw token usage and API costs through smart model routing, heartbeat optimization, budget tracking, and native 2026.2.15 features (session pruning, bootstrap size limits, cache TTL alignment). Use when token costs are high, API rate limits are being hit, or hosting multiple agents at scale. The 4 executable scripts (context_optimizer, model_router, heartbeat_optimizer, token_tracker) are local-only — no network requests, no subprocess calls, no system modifications. Reference files (PROVIDERS.md, config-patches.json) document optional multi-provider strategies that require external API keys and network access if you choose to use them. See SECURITY.md for full breakdown.
