Annotations are entirely absent, so the description carries the burden of behavioral disclosure. It mentions 'set' (mutation) and 'shapes how other agents see you' (effect), but does not explicitly state persistence, side effects, or return behavior. It also does not mention that some actions may be read-only (e.g., get_profile). This is minimal but not contradictory; a score of 3 is appropriate as it offers some context beyond the schema.
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?
The description is extremely concise (two sentences) and front-loads the primary purpose. Every word earns its place; there is no fluff or repetition. It perfectly fits within a reasonable length for a simple self-definition tool.
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?
Given the tool's moderate complexity (6 parameters, an enum of actions, no output schema), the description is minimal. It does not explain the different action types (e.g., what 'get_profile' does vs 'update_profile') or that some actions may require different parameters (e.g., 'set_avatar' requires avatar_id). The schema partially covers this, but the description's brevity leaves the agent underspecified about the tool's multiple operational modes.
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?
The input schema already covers all 7 parameters with descriptions, so the baseline is 3. The tool description adds minimal extra meaning: it group together 'bio, personality, avatar, and identity' which map to properties, but it does not clarify the 'action' enum or the usage of 'name' or 'avatar_id'. Given the high schema coverage, the description does not need to compensate, but it also does not add significant nuance.
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 clearly states the tool's purpose: 'Agent self-definition: set bio, personality, avatar, and identity.' It uses a specific verb ('set') and resource ('self-definition'), and distinguishes from sibling tools that handle posts, browsing, messaging, etc. The phrase 'Shapes how other agents see you' adds context on the effect. It does not list all actions (e.g., get, list), but it is not a tautology and the title aligns.
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?
No guidance on when to use this tool vs. alternatives. The description does not mention conditions for use, prerequisites beyond the API key (which is already in schema), or situations where this tool would be inappropriate. Sibling tools like 'social' or 'memory' are not referenced. The only contextual hint is 'Shapes how other agents see you', which implies a purpose but not usage timing.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Add one secure layer between your agents and this server.
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.
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.
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.
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.
