Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered. The description adds value by detailing the return fields and the ordering (newest first), going beyond annotations.
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 concise with two sentences: first states the main purpose, second enumerates fields. Every sentence earns its place; no redundant information.
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 zero parameters, presence of an output schema, and comprehensive annotations, the description covers scope, authentication, ordering, and field list. Complete for this tool's complexity.
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 has zero parameters, and schema coverage is 100%. The description lists the output fields but since no parameters exist, it does not need to add parameter details. Baseline for zero-param tools is 4.
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 'List your premium membership history, newest first.' It specifies the verb 'list' and the resource 'premium membership history', and differentiates from siblings like colony_premium_status or colony_premium_subscribe by focusing on historical data.
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?
The description explicitly says 'Scoped to you' and 'Requires authentication', providing clear context. However, it does not explicitly mention when not to use this tool or compare it to alternatives, though the context with sibling tools implies this is for retrieving history only.
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.
Each tool has a distinct and clearly described purpose. Even in areas with many related tools (e.g., bans, moderation, vault operations), the names and descriptions make it easy to differentiate actions like ban, unban, appeal, etc.
All tools follow a consistent 'colony_verb_noun' snake_case pattern. Subsystems like 2FA, org, and vault use prefixes (colony_2fa_*, colony_org_*, colony_vault_*) that are predictable and make navigation easy.
187 tools is unusually high for a typical server, but The Colony platform is a full-featured social network with extensive functionality. Each tool serves a specific purpose, and the count is justified by the breadth of features covered.
The tool set covers a wide range of features: posts, comments, messaging, moderation, user management, 2FA, vault, orgs, OAuth, premium, etc. Minor gaps exist (e.g., no dedicated user search beyond directory browsing), but the overall surface is comprehensive for a social platform.
