Cloudflare: cache URL probe

cf_cache_probe
Read-only

Probe one public URL 1-3 times and report CF-Cache-Status, Age, CF-Ray, cache headers, latency, and status transitions. Point-in-time evidence for the responding Cloudflare path/POP; not a global cache inventory.

Input Schema

NameRequiredDescriptionDefault
urlYesPublic URL inside the zone (e.g. https://www.your-tenant.com/asset.js)
zoneYesParent Cloudflare zone name (e.g. your-tenant.com) or zone ID
attemptsNo
timeoutMsNo
context_idNoOptional explicit Connection Hub work context (ctx_*). Omit to use the conversation's active workspace; global Hub tools ignore it.
account_slugNoCloudflare account slug. Required when the workspace has multiple accounts and the zone is not yet cataloged.
environment_slugNoCloud Catalog environment used as an account-routing preference when no zone is provided.

Output Schema

NameRequiredDescriptionDefault
okYes
dataYes
contractVersionYes
dataSchemaVersionYes

TDQS

A4.2/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already establish read-only and non-destructive behavior, while the description adds useful context about repeated probing, status transitions, latency, and the point-in-time nature of the evidence. It does not discuss auth, rate limits, or failure modes, but it meaningfully improves transparency beyond the annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences are front-loaded with the core action and output fields, followed by a scope limitation. There is no filler, and every clause contributes to correct tool selection or interpretation.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description is complete enough for a diagnostic probe with an output schema, annotations, and mostly documented parameters. It covers purpose, outputs, and scope, though it could do more to explain parameter routing and alternative diagnostic tools.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is moderate at 71%, and the schema already describes zone, URL, context_id, account_slug, and environment_slug. The description adds the 1-3 attempt range for the attempts parameter, but it does not clarify timeoutMs or the account/zone routing parameters beyond what the schema provides.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb and resource: it probes one public URL 1-3 times and reports named Cloudflare cache and timing fields. It also distinguishes the tool's scope from a global cache inventory, which helps separate it from analytics-style cache siblings.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The phrase 'Point-in-time evidence for the responding Cloudflare path/POP; not a global cache inventory' gives clear usage context and an exclusion. It does not explicitly name a sibling alternative such as cf_cache_analytics, so it falls short of full when-to-use/when-not guidance.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
