What it does
Vastai Webhooks Events is an agent skill from jeremylongshore/tons-of-skills-marketplace. Analyze, verify, and operate Vast.ai notification webhooks with exact-body HMAC, replay protection, deduplication, durable enqueue, and failure-aware acknowledgment. Use when notification events must drive automation. Trigger with: "receive Vast.ai webhooks", "verify X-Vast-Signature-256", "handle duplicate Vast.ai events".
Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/official-docs.md`). Compatibility notes: Requires a public HTTPS receiver, durable queue and deduplication store, secret manager, and notification webhook access.
It sits in Backend & APIs, covering Webhooks and Data cleaning. 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
- Notification events must drive automation
- With: receive Vast.ai webhooks
- Verify X-Vast-Signature-256
- Handle duplicate Vast.ai events
Example prompts
- “receive Vast.ai webhooks”
- “verify X-Vast-Signature-256”
- “handle duplicate Vast.ai events”
- “/vastai-webhooks-events”
Requirements
- Compatibility (from SKILL.md): Requires a public HTTPS receiver, durable queue and deduplication store, secret manager, and notification webhook access.
- Pre-approved tools (allowed-tools): Read, Grep, Write, Edit
Workflow steps
6 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:
ReadGrepWriteEdit
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
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):
docs.vast.ai
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
Requires a public HTTPS receiver, durable queue and deduplication store, secret manager, and notification webhook access.
From compatibility in the SKILL.md frontmatter.
Context cost
Vastai Webhooks Events loads about 1.1k tokens when it runs, and up to ~1.5k if it reads all its reference files. Until then it costs about 87 tokens; SKILL.md has 450 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.

Signed Vast.ai Notification Receiver
Overview
Vast.ai notifications are signed, at-least-once deliveries. Verify the exact raw body before JSON parsing, reject stale timestamps, deduplicate by stable event ID, enqueue durably, and return success only after acceptance.
Prerequisites
- Full subscription keys such as
client:low_creditorclient:outbid - Public HTTPS endpoint without redirects or private-address resolution
- Webhook secret store, five-minute replay window, durable queue, and event ledger
Instructions
Step 1: Create a bounded subscription
Discover valid notification types and subscribe only the required full client or host keys. Respect the four-webhook-per-user limit and retain context-specific webhooks when short slugs overlap.
Step 2: Store the one-time secret
Capture the signing secret at create or rotate time because list and update responses do not return it. Test retrieval and rotation ownership.
Step 3: Verify raw delivery
Require POST, read exact body bytes, combine integer X-Vast-Timestamp, a period, and raw body, then compare the HMAC-SHA256 against X-Vast-Signature-256 in constant time.
Step 4: Reject replay and duplicates
Reject missing or malformed headers and timestamps older than 300 seconds. Deduplicate retries using X-Vast-Event-Id or payload event_id.
Step 5: Acknowledge after durable enqueue
Persist the verified event and return 2xx quickly. Process side effects asynchronously and idempotently; the delivery timeout is ten seconds.
Step 6: Test and operate failure paths
Use the provider test delivery, verify rotation, and monitor permanent 3xx/most-4xx failures versus retryable 408, 429, 5xx, timeout, or connection errors.
Authentication
Webhook configuration uses the scoped Vast.ai API key; delivery verification uses the distinct webhook secret. Never log either secret or parse/re-serialize JSON before signature verification.
Show full SKILL.md (193 more words)Show less
Tool Discipline
Use Read and Grep to inspect manifests, configuration, provider output, and existing tests before proposing a mutation. Use Write or Edit only for the approved plan, implementation, test, or redacted receipt; do not create, update, destroy, or fund Vast.ai resources without explicit operator approval.
Output
- Subscription keys, webhook ID, and secret-rotation ownership
- Signature, replay, deduplication, enqueue, and idempotency tests
- Delivery health and retry/permanent-failure receipt
Return webhook ID, context keys, test event ID, signature/replay/dedupe results, acknowledgment latency, queue record, and rotation date.
Examples
A client:low_credit delivery is verified from raw bytes, rejected if older than five minutes, deduplicated by event ID, enqueued, and acknowledged with 204 before the worker pages the billing owner.
Error Handling
| Failure | Response |
|---|---|
| Signature or timestamp is invalid | Return a permanent client error and do not enqueue or disclose verification details. |
| Duplicate event arrives | Return success after confirming the original durable record; do not repeat side effects. |
| Queue is unavailable | Return a retryable failure such as 503 rather than acknowledging data loss. |
| Endpoint redirects | Fix the configured final HTTPS URL because redirects are permanent delivery failures. |
