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

With no annotations, the description carries the full behavioral burden. It discloses useful behavior such as timestamp fallback to the most recent snapshot and list_snapshots mode, but it omits rate limits, authentication expectations, error behavior when no snapshot exists, and what the retrieved page content includes.

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

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

The description is front-loaded with the core purpose and then structured into a compact Args list. It is appropriately sized, with each detail contributing to correct invocation.

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

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

For a four-parameter archival tool with no annotations and an output schema, the description covers the essential operational modes and all parameters. It is complete enough to invoke correctly, though it could better state relationships to live-scraping alternatives and failure cases.

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

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

Schema description coverage is 0%, so the description must compensate, and it mostly does: it explains url, the 14-digit timestamp format and default behavior, list_snapshots mode, and limit/default. Minor gaps remain, such as whether limit applies only in snapshot-listing mode.

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

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

The description states a specific verb and resource: retrieving archived snapshots from the Internet Archive's Wayback Machine, including historical or deleted pages. It clearly distinguishes itself from live-scraping siblings by specifying archival retrieval, though it does not explicitly name an alternative tool.

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

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

Usage is implied by 'historical recon' and 'deleted or past webpages,' suggesting this tool is for archived rather than live content. However, it provides no explicit when-to-use or when-not-to-use guidance against siblings like scrape_url or search_web.

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