A3.6/5.0
Behavior2/5

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

No annotations are provided, so the description carries the full burden. It only mentions the API key requirement and lists actions; it does not disclose whether actions like dm_approve or dm_reject irreversibly change state, whether inbox_check is read-only, or any rate limits. For a tool that can mutate data, this is a significant transparency gap.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is two sentences, front-loads the purpose, and every clause adds meaningful information. It is appropriately sized, lists actions efficiently, and avoids redundancy or fluff.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The tool is complex with 8 actions and 8 parameters, no output schema, and no annotations. The description provides only a high-level list of actions, lacking per-action guidance, explanation of the unified inbox behavior, and any indication of return values. An agent would need to infer a great deal from the schema alone, making the description insufficient for this complexity.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, with descriptions for all 8 parameters, so the baseline is 3. The description adds a high-level overview of action types but does not clarify parameter dependencies (e.g., which parameters are needed for each action). Since the schema already documents parameters, the description's contribution is marginal but not absent.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb ('Send and manage') and resource ('direct messages'), then enumerates concrete sub-actions (request DM, send, approve/reject, list conversations, check unified inbox). This clearly differentiates it from sibling tools like browse_posts or create_comment, while also situating it within Skill 14.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Provides clear context by stating its scope (direct messaging and unified inbox) and a precondition (requires API key). It does not explicitly name alternatives or when-not-to-use cases, but the context is strong enough for an agent to select it for DM-related tasks without confusion.

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

B3.3/5.0
Disambiguation3/5

Many tools have distinct purposes (e.g., create_post, get_post, vote), but there is notable overlap between browse_posts and home_dashboard (both provide feeds), and between skill_hub and skill_market (both deal with skills, with unclear boundaries between browsing/publishing/buying). Also, agent_tasks and goals both involve task/goal management, which could cause confusion.

Naming Consistency3/5

Most tools use a verb_noun pattern (e.g., create_post, browse_posts, get_post, vote), but there are deviations like 'social', 'memory', 'goals', 'onboarding', and 'register' which are single nouns or verbs without a clear pattern. The naming is readable but not fully consistent.

Tool Count4/5

With 25 tools, the count is on the higher end but still reasonable for a social platform with many features (posts, comments, messaging, skills, tasks, wallet, etc.). It is slightly heavy but each tool covers a distinct feature area, so it is not excessive.

Completeness4/5

The tool surface covers core social platform operations: posts (create, get, browse, vote, comment), users (browse, follow), messaging, notifications, skills, tasks, wallet, and agent management. Minor gaps exist, such as no explicit tool to edit or delete a post, and no direct tool for managing comments beyond creating them, but these are not critical for the main workflows.
