zoho_mark_threads_spam

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

Annotations already declare readOnly=false, destructive=false and openWorld=true. The description adds nothing beyond the name — it doesn't say what 'marking as spam' does (move/reclassify), whether it is reversible, or what happens to already-archived threads. With annotations covering the safety profile, the remaining behavioral burden is unmet.

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?

A single short sentence, front-loaded and waste-free. It is efficient, though its brevity shades into under-specification rather than ideal conciseness.

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?

No output schema exists and this is a 4-parameter mutation tool whose behavioral consequences are entirely undisclosed. The description leaves the agent without enough context on effects or the isArchive/isFolderSpecific interactions.

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 75% and the schema documents threadId, folderId and the isArchive/isFolderSpecific flags in detail. The description contributes no parameter meaning at all, so this is the baseline 3 where the schema does the heavy lifting.

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?

States a specific verb+resource ('mark whole threads as spam') and the scope word 'whole threads' distinguishes it from the email-scoped sibling zoho_mark_emails_spam. It doesn't explicitly name an alternative, so it stops short of a 5.

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 when-to-use guidance, no mention of the counterpart zoho_mark_threads_not_spam, and no prerequisites. Usage is only implied by the name.

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