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

Annotations already declare readOnlyHint=true, idempotentHint=true and destructiveHint=false, so the safety profile is covered. The description usefully adds what the response contains, but with no output schema it does not say what happens when the id is unknown, how the project is resolved, or whether all networks are always returned.

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 front-loaded sentence with no wasted words; the colon-separated enumeration of returned fields is easy to scan. It is slightly terse to the point of being cryptic in 'the current version for each of its networks'.

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 a two-parameter read tool with no output schema, the description gives a reasonable sketch of the return shape but leaves gaps: the shape of the per-network version objects, not-found behavior, and the role of the project parameter are all unaddressed. Adequate for a simple getter, but not fully self-sufficient.

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 post_id (sourced from uptake_posts or uptake_write_post) and project (id or site, optional for single-project makers) are already documented. The description's phrase 'by its id' adds nothing beyond the schema and never mentions the project parameter at all, so the baseline of 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?

The description names a specific resource (one post by id) and enumerates the payload it returns: the current version per network, whether it is posted, and whether it carries a tracked link. This distinguishes it implicitly from the list-oriented uptake_posts and the mutation sibling uptake_edit_post, though it never names those siblings directly.

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?

Usage is only implied: an agent can infer that this is the lookup to use when it needs detail on one known post id. There is no explicit when-to-use, no exclusion (e.g. 'do not use to list posts, use uptake_posts'), and no note about when the optional project parameter must be supplied.

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