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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered. The description adds meaningful context beyond that — that results combine local snapshots with live windows, and that output is informational only — but it says nothing about data freshness limits, how far back local snapshots reach, or pagination/result size. It does not contradict 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.

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

Two short sentences with no filler, and the resource scope is front-loaded before the disclaimer. The compression comes at a cost, though — dense abbreviations like 'HL/Thirdfy' reduce comprehension without saving much space.

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 read-only data-retrieval tool with no output schema and 33% parameter coverage, the description should explain what 'id' identifies and roughly what the returned history contains. It covers neither, and the only compensating content is a legal disclaimer, leaving the agent under-informed about inputs and results.

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 coverage is only 33%: api_key is fully documented in the schema, but id and days are not. The description references 'id=' without specifying its format or where to obtain it, and 'day/week/month windows' loosely maps to the integer days parameter (default 7, title says 7-day) but never states that days controls the window length. It adds partial meaning but leaves real gaps.

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 identifies the resource (history snapshots for a given bot id) and the data sources (local HL/Thirdfy snapshots plus live day/week/month windows), but the verb is only implied and the abbreviations 'HL/Thirdfy' are unexplained jargon. It gives no hint of how it differs from siblings like bot_sheet or free_bot_sheet_sample, so an agent cannot distinguish it from those by the description alone.

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?

There is no explicit when-to-use or when-not-to-use guidance. The mention of 'live day/week/month windows' hints that the tool can serve short- and long-range lookups, but it never states which situations call for this versus bot_sheet, bots_top, or the free sample, nor any prerequisites beyond what the schema implies.

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