Juicebox Webhooks Events

What it does

When your agent uses it

• Tasks that involve Webhooks

Example prompts

• “juicebox webhooks”
• “juicebox events”
• “/juicebox-webhooks-events”

Requirements

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

Workflow steps

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

1. 1Authenticate origin before parsing, validate timestamp/event ID, and reject unknown sources, stale deliveries, and malformed payloads.
2. 2Store only a bounded redacted envelope and use event ID plus target revision as the idempotency key.
3. 3Verify source authority, suppression, and destination before enqueueing enrichment; quarantine uncertainty instead of exporting or…
4. 4Canary one sandbox source, observe aggregate policy probes, then promote or disable the consumer.
5. 5Route exhausted retries to reviewed recovery without replaying non-idempotent writes.

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
  • 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

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

  • api.juicebox.ai

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

• Credentials

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

  • JUICEBOX_WEBHOOK_SECRET
  • JUICEBOX_API_KEY

  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

Juicebox Webhooks Events loads about 1.3k tokens when it runs, and up to ~2.5k if it reads all its reference files. Until then it costs about 28 tokens; SKILL.md has 299 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~28

When it runs · the whole SKILL.md, loaded when a task matches

~1.3k

With references · SKILL.md plus every file in references/, read only if the agent opens them

~2.5k

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

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.
