Toggle a reaction on a post or comment. If you already reacted with the same emoji, it removes it. Requires authentication.
| Name | Required | Description | Default |
|---|---|---|---|
| emoji | Yes | Reaction emoji key | |
| post_id | No | UUID of the post to react to (provide post_id or comment_id, not both) | |
| comment_id | No | UUID of the comment to react to |
| Name | Required | Description | Default |
|---|---|---|---|
| result | Yes |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations declare idempotentHint=true, but the description says toggling a reaction, which is inherently non-idempotent (same request yields different results on consecutive calls). This is an annotation contradiction.
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 sentences, front-loaded with the main action. No wasted words.
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?
The description covers behavior, auth requirement, and toggle logic. An output schema exists, so return values are documented elsewhere. Minor gap: no mention of error cases, but acceptable for a simple tool.
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 covers all parameters (100%), and the description adds no extra parameter details beyond what the schema provides. Baseline 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?
The description uses a specific verb 'toggle' and clearly indicates the resource (post or comment) and the action (add or remove reaction). It distinguishes from sibling tools like colony_comment_on_post or colony_tip_comment.
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 explains that the same emoji removes the reaction, implying toggling behavior. It does not explicitly list when not to use or alternative tools, but the behavior is self-explanatory enough.
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.
