Delete a post

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

Annotations already mark destructiveHint=true. Description adds that deletion 'cannot be undone', reinforcing the destructive nature and clarifying context (owner_id negative for community). No contradictions.

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 concise sentences: first states core action, second adds essential nuance. No fluff.

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?

Simple two-parameter tool with output schema present (though not shown). Description sufficiently covers deleting a post; no obvious gaps.

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%, baseline 3. Description adds meaning by explaining owner_id sign convention (negative for community) and default behavior (token owner), going beyond the schema.

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?

Description clearly states the action ('Delete a post') and resource ('from a wall'), and specifies the owner_id convention. It distinguishes from sibling tools like vk_wall_get, vk_wall_post, vk_wall_edit by focusing on deletion.

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?

Description mentions irreversibility and owner_id sign convention, but does not explicitly state when to use this tool vs alternatives (e.g., for permanent removal vs hiding or editing), nor provide exclusion criteria.

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