What it does

Clickup Webhooks Events is an agent skill from jeremylongshore/tons-of-skills-marketplace. Register, verify, process, monitor, and reconcile ClickUp webhooks with raw-body HMAC, durable idempotency, fast acknowledgment, and gap recovery. Use when building event-driven ClickUp integrations. Trigger with "ClickUp webhook", "verify X-Signature", or "ClickUp 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: Designed for Claude Code; registration requires authorized ClickUp access and public HTTPS ingress

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

  • Building event-driven ClickUp integrations
  • With ClickUp webhook
  • Verify X-Signature

Example prompts

  • “ClickUp webhook”
  • “verify X-Signature”
  • “ClickUp events”
  • “/clickup-webhooks-events”

Requirements

  • Compatibility (from SKILL.md): Designed for Claude Code; registration requires authorized ClickUp access and public HTTPS ingress
  • Pre-approved tools (allowed-tools): Read, Glob, Grep, WebFetch, Write, Edit

Workflow steps

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

  1. Choose the narrowest location and explicit event set; inventory duplicate registrations before creation.
  2. Register only after endpoint ownership, HTTPS, secret storage, and rollback approval are confirmed.
  3. Capture raw bytes, look up the per-webhook secret, verify HMAC in constant time, then parse/validate JSON.
  4. Persist idempotency and enqueue before a fast success response; process business effects asynchronously.
  5. Monitor status/fail count, latency, duplicates, dead letters, and owner eligibility.
  6. Run reconciliation reads for delivery gaps and rotate/re-register safely when ownership changes.

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
    • WebFetch
    • 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

    Links to these hosts (documentation or services it may open):

    • developer.clickup.com

    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

    Designed for Claude Code; registration requires authorized ClickUp access and public HTTPS ingress

    From compatibility in the SKILL.md frontmatter.

Context cost

Clickup Webhooks Events loads about 1.1k tokens when it runs, and up to ~1.7k if it reads all its reference files. Until then it costs about 75 tokens; SKILL.md has 431 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~75
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.7k

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.

ClickUp Signed Webhook Operations

Overview

Treat webhooks as signed, user-owned change signals that need durable processing and reconciliation. Assume delivery can duplicate, arrive late, or stop after ownership changes.

Prerequisites

  • A public HTTPS endpoint capable of retaining raw request bytes
  • A secret manager, durable queue/idempotency store, and Workspace allow-list
  • An authorized user owner for the webhook plus monitoring and reconciliation

Tool Discipline

Use Read, Glob, and Grep to inspect the repository, adapters, configuration names, tests, and evidence. Use WebFetch only for current official ClickUp documentation. Use Write or Edit after confirming the target file, Workspace boundary, and requested mode.

Current Contract

  • Webhook creation returns a unique secret; verify raw-body HMAC-SHA256 against hexadecimal X-Signature.
  • Registrations are tied to the creating user and can stop triggering when that user is disabled or loses hierarchy access.
  • Use webhook_id:history_item_id as the documented idempotency key when a history item exists; handle events without one deliberately.
  • Responses over seven seconds or unsuccessful responses are failures; ClickUp attempts delivery up to five times, does not resend the failed event later, suspends at fail_count=100, and a 401 suspends immediately.

Authentication

Use a personal token only for accountable individual/testing work or OAuth Authorization Code for a user-facing integration. Inject the token server-side through a governed secret reference, send it in Authorization, verify authorized Workspace IDs, and never print the token, OAuth client secret, or webhook secret.

Instructions

  1. Choose the narrowest location and explicit event set; inventory duplicate registrations before creation.
  2. Register only after endpoint ownership, HTTPS, secret storage, and rollback approval are confirmed.
  3. Capture raw bytes, look up the per-webhook secret, verify HMAC in constant time, then parse/validate JSON.
  4. Persist idempotency and enqueue before a fast success response; process business effects asynchronously.
  5. Monitor status/fail count, latency, duplicates, dead letters, and owner eligibility.
  6. Run reconciliation reads for delivery gaps and rotate/re-register safely when ownership changes.

Approval Boundaries

Require approval before creating, broadening, suspending/reactivating, rotating, or deleting production webhooks and before replaying business effects.

Output

Return the registered scope, credential-storage identifier, HMAC verification and idempotency test results, delivery health, queue result, reconciliation status, and rollback.

Error Handling

ConditionResponse
Signature invalidReject before parsing and record content-free evidence.
Handler cannot persist within deadlineReturn failure deliberately and repair capacity; do not acknowledge lost work.
Webhook suspendedContain, diagnose fail count/401 behavior, and reactivate only after approval.
History item is absentUse a documented event-specific fallback key and reconciliation.

Examples

The example below is a redacted operator receipt; it contains no task text, member data, credential, or webhook secret.

text
events=taskUpdated,taskDeleted; hmac=pass; ack=82ms; duplicate=ignored; fail-count=0; reconcile=pass
