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

Annotations already declare destructiveHint=true, readOnlyHint=false, and openWorldHint=false, so the agent knows this mutates state. The description usefully signals that the operation is bidirectional (unarchive exists), implying reversibility, but it does not say what archiving does to a template already used in sequences, nor correct the arguably harsh destructive=true framing for a reversible toggle.

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?

Very short and front-loaded, but the second clause 'Archive email templates' is redundant with the first and consumes roughly half the text without adding information.

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?

Output schema exists and all three parameters are documented, so the structured data carries most of the load. Still missing is any note on side effects (e.g. whether archived templates still render in sequences) that would matter for a destructive-flagged toggle.

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 100%: id, archived (default true), and workspace_id fallback behavior are all documented in the schema. The description adds no syntax, defaults, or semantics beyond that, so baseline 3 applies.

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 pair (Archive/Unarchive) and resource (Template/email templates), which lets an agent distinguish it from archive_list, archive_sequence, and archive_contact. The trailing 'Archive email templates' merely restates the verb+resource rather than adding scope.

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?

No indication of when to archive versus using update_template, delete_*, or get_template, and no mention of prerequisites or alternatives among the many archive_* siblings. Usage is only inferable from the word 'Archive' itself.

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