get_postGet one post with its per-platform variants. Variant ids from here are what update_post uses to edit individual captions. Also finds drafts, which list_posts (month-scoped) can miss.

+}Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and destructiveHint=false, so safety is covered. The description adds genuinely useful behavior: the response contains per-platform variants whose ids are the handles update_post needs, and it surfaces drafts that a month-scoped list would omit. It stops short of noting lookup failure behavior for an invalid or missing id.
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 the tool returns, then the downstream use, then the draft edge case. No redundant restatement of the title or annotations.
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?
An output schema exists, so return values need no full explanation, and the description still highlights the important part of the payload (variant ids). Together with the annotations this is nearly complete; only error/not-found behavior is unaddressed.
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 coverage is 100% and the single id parameter is documented as a UUID with its provenance ('from list_posts or create_post'). The description adds nothing about the id beyond the schema, 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?
States a specific verb and resource ('Get one post') plus the scope of what is returned ('with its per-platform variants'). It distinguishes itself from list_posts (month-scoped, can miss drafts) and links to update_post via variant ids, so an agent can tell it apart from every relevant sibling.
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?
Gives a clear condition for choosing it: fetch a single post, including drafts that list_posts may miss, and use it to obtain variant ids before calling update_post. It does not state explicit when-not-to-use cases (e.g., bulk retrieval), but the routing context is strong.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
