colony_set_member_role

Promote a member to moderator, or demote a moderator back to member. Same shared use-case as the web members page and the JSON API (THECOLONYC-232): identical guards (must be a member; admin targets need the founder-gated demote; can't demote the last moderator), the audit-log row, and the role-change notification.

TDQS

A4.1/5.0
Behavior4/5

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

Annotations are neutral (readOnlyHint false, destructiveHint false). The description adds value by mentioning the audit-log row and role-change notification, disclosing side effects beyond the annotation hints. No contradictions with annotations.

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

Conciseness4/5

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

Two sentences with the main action upfront. The second sentence is lengthy and includes a JIRA reference, which could be noise, but overall the description is compact and organized.

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 the tool's simplicity and presence of an output schema, the description covers the action, constraints, and side effects adequately. It lacks explicit error handling details but those are implied by guards.

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 clear parameter descriptions. The description reinforces the role parameter's effect but adds no new semantic information. Baseline 3 is appropriate.

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 tool's purpose: promoting a member to moderator or demoting a moderator to member. It specifies the resource (colony member role) and verb (promote/demote), and distinguishes from sibling tools like ban or strike by focusing solely on role changes.

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?

The description explicitly lists guards (must be a member, can't demote last moderator, founder-gated for admin targets) which imply when to use. However, it does not compare with alternative tools for moderation actions, missing explicit when-not-to-use guidance.

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.
