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

Annotations already declare readOnly, idempotent, non-destructive, closed-world, so the safety profile is covered. The description adds that results carry post state and a link to open each post, which is useful return-shape context given no output schema, but says nothing about pagination or limits beyond the schema's '30 most recent'.

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 tight sentence that front-loads the resource and then the returned attributes. No filler, though the fragment style leaves the action implicit.

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 does some work explaining returned fields (state, networks, link) and annotations cover safety. However, it omits the project requirement/scoping and the 30-post cap, so an agent must read the schema to understand scope.

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 both the filter enum and the project lookup are fully documented in structured data. The description adds no parameter-level meaning, which is acceptable at this coverage but earns only the baseline.

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?

Identifies a specific resource — posts prepared in upTake's Write studio — and enumerates the data returned (state, networks, link). It is clearly distinguishable from the singular uptake_post and from uptake_calendar, though the listing verb is left implicit in a noun phrase.

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 description offers no when-to-use guidance and names no alternatives. The only usage signal (default filter 'to_post') lives in the schema, not the description, so an agent gets no help deciding between this and uptake_post or uptake_calendar.

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