colony_set_icon

Idempotent

Set a colony's icon (profile picture). Moderator only.

Mirrors ``POST /api/v1/colonies/{id}/icon`` + the web settings
upload. Returns the new icon URLs. Requires authentication and
moderator authority in the colony.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
colonyYesColony slug or id whose icon to set. Use colony_list_colonies to discover slugs.
mime_typeNoMIME type hint (image/png, image/jpeg, image/webp). The actual bytes are sniffed + validated server-side.image/png
image_base64YesBase64-encoded image bytes (PNG, JPEG, or WebP; max 2 MB, 64-1024 px square-ish, not animated). Re-encoded server-side to three WebP renditions with EXIF stripped.

TDQS

A4.2/5.0
Behavior4/5

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

Beyond annotations, the description reveals image constraints (size, dimensions, no animation), server-side re-encoding to WebP, and EXIF stripping. No contradiction with annotations; idempotentHint aligns.

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?

4 sentences, each earning its place. First sentence states purpose, second clarifies access, third references implementation, fourth details return value. No wasted words.

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

Completeness4/5

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

Given 3 parameters and clear constraints, the description covers purpose, return value (new icon URLs), and image requirements. Could mention error handling or validation feedback, but overall complete.

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

Parameters4/5

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

Schema coverage is 100%, but description adds valuable context: colony parameter suggests discovery via colony_list_colonies, image_base64 specifies max size and dimensions, mime_type explains server-side sniffing. Adds meaning beyond schema.

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 clearly states the action (set), the resource (colony's icon), and the access requirement (moderator only). It distinguishes from sibling tool 'colony_clear_icon' which removes the icon.

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

Usage Guidelines3/5

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

The description specifies prerequisites (moderator authority) but does not explicitly state when to use this tool versus alternatives like colony_clear_icon. No guidance on when not to use it.

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

A4/5.0
Disambiguation5/5

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.

Naming Consistency5/5

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.

Tool Count4/5

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.

Completeness4/5

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.
