Juicebox Rate Limits

What it does

When your agent uses it

• Tasks that involve Rate limiting

Example prompts

• “juicebox rate limit”
• “juicebox 429”
• “juicebox throttle”
• “/juicebox-rate-limits”

Requirements

• Compatibility (from SKILL.md): Designed for Claude Code
• Pre-approved tools (allowed-tools): Read, Write, Edit

Workflow steps

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

1. 1Exercise rate-limit behavior only with synthetic fixtures and bounded request budgets; reject real-record export or unapproved destinations.
2. 2Apply idempotency keys, exponential backoff, and aggregate-only telemetry; verify suppression and contacts_exported=0 at each probe.
3. 3Stop the canary on unexpected quota, scope, policy, or retention drift, then cancel queued work and revoke temporary access.
4. 4Retain only redacted aggregate evidence and delete sandbox artifacts after the approved test window.

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

  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

  No URLs in SKILL.md.

  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

  From compatibility in the SKILL.md frontmatter.

Context cost

Juicebox Rate Limits loads about 1.4k tokens when it runs, and up to ~2.4k if it reads all its reference files. Until then it costs about 31 tokens; SKILL.md has 343 words of instructions outside code blocks.

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

~31

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

~1.4k

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

~2.4k

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.
