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

Annotations already cover the safety profile (readOnlyHint, idempotentHint, destructiveHint=false, openWorldHint=false), yet the description adds non-obvious context: the data is a last-observed snapshot rather than live state, no provider call is made, and the caller needs integrations:read plus tickets:read. That staleness and permission disclosure is real value beyond the annotations; it just doesn't cover caching/refresh behavior.

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?

Three short sentences, front-loaded with what is read, followed by the staleness caveat and the permission requirement. No filler; each sentence carries distinct 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?

With no output schema, the description is responsible for signaling return content, and it does ('saved links plus unresolved write effects that need reconciliation'). Combined with the staleness note and scopes, an agent has enough to invoke it correctly; only the routing to reconcile/effect siblings is missing.

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 carry parameter meaning. It adds the ownership constraint ('one owned ticket') which is not in the schema, but never explains the ticket_id identifier itself beyond what the schema's UUID pattern conveys. Given a single self-evident parameter, this is adequate but thin.

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 gives a specific verb ('Read'), a bounded resource ('one owned ticket's saved GitHub, GitLab and Asana links'), and extends scope to 'unresolved write effects that need reconciliation'. That is far more than a restatement of the name. It stops short of naming a sibling (e.g. list_ticket_provider_effects) as the alternative, so differentiation is implied by the single-ticket scope 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?

'Read one owned ticket's...' and 'No provider request' imply this is the passive, cached lookup for a single ticket, which contrasts with live/sync siblings, but no alternative is named and no exclusion is given. Usage is inferable rather than explicit.

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