Website Change Monitor & Deterministic Diff

industrial_platform/web-change-intelligence

industrial_platform--web-change-intelligence

Destructive

This tool calls the Actor "industrial_platform/web-change-intelligence" and retrieves its output results. Actor description: Website change detector and deterministic diff API for AI agents. Monitor pricing, availability, documentation, policies, and competitor pages. $0.001 per successful comparison.

This tool requires an x402 payment. Include a valid x402 payment signature in the request metadata (_meta["x402/payment"]). Your MCP client must support the x402 payment protocol.

Input Schema

TableJSON Schema

Name	Required	Description
`url`	Yes	REQUIRED Public http:// or https:// URL to inspect. Example values: "https://example.com/"
`selector`	No	Optional CSS selector that restricts monitoring to a specific part of an HTML page, such as main, #pricing, or .inventory.
`waitSecs`	No	Max seconds (0–45, default 30) to cap the wait for the Actor run to reach terminal state. For long-running Actors the response returns at the cap with the current run status; follow `nextStep` to poll via get-actor-run. Set to 0 to fire-and-forget.
`previous_hash`	No	Optional current_hash from a previous run. Use this for compact changed/unchanged checks when a detailed diff is not required.
`previous_text`	No	Optional current_text returned by a previous run. When provided, the Actor returns deterministic added/removed excerpts and change metrics.
`max_diff_chars`	No	Maximum length returned for each added/removed excerpt. Example values: 12000
`max_text_chars`	No	Maximum characters retained before hashing and comparison. Keep this value consistent across repeated checks. Example values: 100000
`timeout_seconds`	No	Maximum time allowed for the target request. Example values: 30
`ignore_selectors`	No	Optional HTML selectors to remove before comparison, useful for clocks, rotating banners, ads, or other volatile regions.
`include_current_text`	No	Return current_text so a later run can perform a detailed text comparison. Example values: true

B3.3/5.0

Behavior3/5

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

Annotations declare readOnlyHint=false, destructiveHint=true, openWorldHint=true, so the agent already knows this is a non-read-only, potentially destructive, open-world operation. The description adds valuable context: x402 payment is required via _meta["x402/payment"] and the client must support the protocol. It does not explain what 'destructive' means here or what side effects (writes, cost) occur beyond pricing.

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

Conciseness3/5

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

The description is short but mixes three things: tool mechanics, Actor marketing blurb with a price, and the x402 protocol requirement. The pricing sentence ('$0.001 per successful comparison') is somewhat promotional. The payment prerequisite is front-loadable but appears after the Actor marketing line.

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

Completeness3/5

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

An output schema exists, so return-value explanation is not required. However, the tool is a wrapping Actor call with a required payment protocol and destructiveHint=true, and the description does not clarify the relationship to sibling run/dataset tools, nor the cost model implications. It is minimally complete but leaves gaps for correct invocation.

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 description coverage is 100%, so the schema already documents all 10 parameters thoroughly, including url, selector, waitSecs, previous_hash, previous_text, and diff/text char limits. The description adds no parameter-level detail beyond naming the x402 meta key. Baseline 3 is appropriate when the schema does the heavy lifting.

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

Purpose4/5

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

The description states a clear verb and resource: it calls the Actor 'industrial_platform/web-change-intelligence' and retrieves its output. The Actor description adds a concrete capability — 'Website change detector and deterministic diff API' for monitoring pricing, availability, docs, and competitor pages. That distinguishes it well from generic run tools, though it's framed as an Actor-invocation rather than stating the underlying task directly.

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

Usage Guidelines3/5

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

The description implies usage (detecting website changes, monitoring pages) but does not explicitly say when to use this versus siblings like get-actor-run or get-dataset-items. The x402 payment note gives a prerequisite, but conditional routing guidance ('use this when you need a diff, not just a fetch') is absent.

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