Edit Tracker entity checklist item

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

Annotations already declare the safety profile (readOnly=false, idempotent=true, destructive=false, openWorld=true). The description usefully adds the return shape ('Returns the entity with its updated checklist'), which matters because there is no output schema, but it says nothing about partial-update semantics, notification behavior, or side effects.

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, front-loaded with the action and scope, with the return behavior placed second. No filler, though it is terse enough that the parenthetical field list spends words on information already in the schema.

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 an 8-parameter, nested-body mutation with no output schema, the description covers the return value but leaves key operational details unstated: whether omitted/null fields leave values unchanged, and what the notification flags actually do. Adequate minimum, with clear gaps around partial-update behavior.

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%, so the schema already documents all 8 parameters including the nested body and deadline object. The description's parenthetical (text, checked state, assignee, deadline) merely restates schema fields and adds no meaning about null defaults, notify/notify_author, or entity_type values.

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 (Edit) and resource (one checklist item on a Tracker entity) and enumerates the editable fields, which separates it from the sibling that edits the whole checklist (tracker_entities_checklists_update) or deletes an item. It never names those siblings explicitly, so the differentiation is inferable rather than stated.

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?

The scope wording ('Edit one checklist item') implies when to use it versus the checklist-level update/delete siblings, but there is no explicit when-to-use, when-not-to-use, or prerequisite guidance (e.g., permissions, whether the parent checklist must exist). Usage is implied only.

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