What it does

Ideogram Webhooks Events is an agent skill from jeremylongshore/tons-of-skills-marketplace. Verify and reconcile Ideogram async webhooks with Ed25519 signatures, replay controls, deduplication, and polling fallback. Use when implementing or auditing an event receiver. Trigger with "verify an Ideogram webhook", "build Ideogram async callbacks", or "debug duplicate Ideogram events".

Its SKILL.md is about 1.2k 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: Designed for Claude Code; receiver tests should use local signed fixtures

It sits in Backend & APIs, covering Webhooks. 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

  • Auditing an event receiver
  • With verify an Ideogram webhook
  • Build Ideogram async callbacks
  • Debug duplicate Ideogram events

Example prompts

  • “verify an Ideogram webhook”
  • “build Ideogram async callbacks”
  • “debug duplicate Ideogram events”
  • “/ideogram-webhooks-events”

Requirements

  • A credential in IDEOGRAM_API_KEY
  • Compatibility (from SKILL.md): Designed for Claude Code; receiver tests should use local signed fixtures
  • Pre-approved tools (allowed-tools): Read, Glob, Grep, Write, Edit

Workflow steps

7 steps, taken from the first numbered list in SKILL.md.

  1. Capture the raw body bytes and required generation-ID, user-ID, timestamp, key-ID, and signature headers before JSON parsing.
  2. Compute SHA-256 over the raw body and construct the signed message as generation ID, newline, user ID, newline, timestamp, newline, then…
  3. Resolve the key ID from the JWKS cache and verify the lowercase-hex Ed25519 signature.
  4. Enforce a bounded timestamp window and bind the callback to a known submitted generation and expected application tenant.
  5. Persist a deduplication record keyed by generation and delivery evidence, return 2xx quickly, and enqueue processing.
  6. Validate safety, download approved output, persist it, and transition state idempotently.
  7. On verification failure, refresh JWKS once; on missing delivery, append the returned generation ID to GET /v1/generations/ and poll that…

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
    • Glob
    • Grep
    • Write
    • Edit

    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

    Hosts in commands or code, which the agent is likely to contact:

    • api.ideogram.ai

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

  • Credentials

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

    • IDEOGRAM_API_KEY

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

  • Compatibility

    Designed for Claude Code; receiver tests should use local signed fixtures

    From compatibility in the SKILL.md frontmatter.

Context cost

Ideogram Webhooks Events loads about 1.2k tokens when it runs, and up to ~1.8k if it reads all its reference files. Until then it costs about 79 tokens; SKILL.md has 521 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~79
When it runs · the whole SKILL.md, loaded when a task matches
~1.2k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.8k

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.

Ideogram Webhook Verification and Reconciliation

Overview

Accept Ideogram asynchronous completion only after cryptographic verification and idempotent reconciliation. Use the raw request body, bind all signed headers, acknowledge quickly, and retain polling as a recovery path because delivery is not guaranteed.

Prerequisites

  • A public HTTPS receiver, raw-body access, durable event store, queue, and clock.
  • The submitted generation_id, destination object policy, and polling reconciler.
  • Local Ed25519 fixtures for valid, invalid, stale, duplicate, and rotated-key deliveries.

Current Contract

Async requests can include a webhook URL and return generation_id. Ideogram signs callbacks with Ed25519 and publishes keys at https://api.ideogram.ai/v1/.well-known/jwks.json. Signed headers identify generation, user, timestamp, key, and signature. Deliveries may duplicate, retries are limited, and polling remains necessary.

Authentication

Webhook trust comes from signature verification, not a shared API key in the callback. Normal polling uses server-side IDEOGRAM_API_KEY in the Api-Key header; never expose it to the receiver request.

Instructions

  1. Capture the raw body bytes and required generation-ID, user-ID, timestamp, key-ID, and signature headers before JSON parsing.
  2. Compute SHA-256 over the raw body and construct the signed message as generation ID, newline, user ID, newline, timestamp, newline, then the lowercase body hash.
  3. Resolve the key ID from the JWKS cache and verify the lowercase-hex Ed25519 signature.
  4. Enforce a bounded timestamp window and bind the callback to a known submitted generation and expected application tenant.
  5. Persist a deduplication record keyed by generation and delivery evidence, return 2xx quickly, and enqueue processing.
  6. Validate safety, download approved output, persist it, and transition state idempotently.
  7. On verification failure, refresh JWKS once; on missing delivery, append the returned generation ID to GET /v1/generations/ and poll that resource.

Tool Discipline

Use Read, Glob, and Grep for receiver, queue, state, and fixtures. Use Write and Edit for approved implementation and tests. Do not expose a receiver, submit paid async work, or replay production events by invocation alone.

Show full SKILL.md (208 more words)Show less

Approval Boundaries

Require approval for public routing, production keys, live submissions, replay-window changes, retained identifiers, and storage or publishing. Reject callbacks that cannot be tied to an authorized application operation.

Error Handling

  • Never verify reserialized JSON; whitespace changes break raw-body integrity.
  • Refetch JWKS once on an unknown key or verification failure, then reject.
  • Duplicate or late valid delivery is an idempotency case, not authority to create another asset.

Output

Return receiver route class, signature and replay result, opaque generation ID, duplicate state, acknowledgment latency, downstream terminal and storage state, polling fallback, and cleanup. Exclude headers, bodies, URLs, prompts, and images.

Examples

  • Verify a fixture signed over exact raw bytes, acknowledge, then prove one durable state transition across two deliveries.
  • Report signature=pass; replay=fresh; duplicate=yes; transitions=1; poll_fallback=not-needed.

Validation

Test byte mutation, header mutation, stale timestamps, unknown and rotated keys, duplicates, out-of-order state, unsafe output, polling fallback, and object deletion. Confirm receiver logs contain no signed body or content.

Resources

  • Current first-party evidence map — use the dated endpoint, webhook, billing, team, and training links as the contract index for this workflow.
  • Recheck the endpoint-specific page and current OpenAPI description before relying on an enum, limit, beta feature, or lifecycle claim.
  • Record live observations as environment-specific evidence, not as universal vendor guarantees.
