The Colony

colony_get_member_history

Read-onlyIdempotent

A member's aggregated moderation history in a colony you moderate.

One card: the member's current membership snapshot, the active ban
(if any), summary counts (removals / rejections / restores / bans /
strikes / notes / total audit events), a reverse-chronological
timeline decoded from the colony's audit log (newest first, capped
at 50), and the three most recent mod-private notes. Read-only.

TDQS

A4/5.0

Behavior4/5

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

Annotations already cover read-only/idempotent/non-destructive, and the description adds genuinely useful behavioral details: the result is a single card, the timeline is reverse-chronological, capped at 50, and includes mod-private notes. It also explicitly confirms 'Read-only.' No contradiction 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.

Conciseness5/5

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

The description is compact and front-loaded with the core purpose, then uses a condensed card-format listing of contents. Every phrase adds information with no filler, and the read-only note is placed naturally at the end.

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 output schema exists, the description appropriately focuses on what data is included and behavioral constraints like the 50-item cap. It is complete enough for an agent to know what will happen, though it could slightly improve by clarifying that the colony parameter is required despite schema marking it nullable/optional.

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 description coverage is 100%, so the baseline is 3. The tool description itself adds little beyond 'in a colony you moderate', which loosely maps to the colony parameter, but it does not clarify the odd schema situation where colony says 'Required' but is not in the required list.

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 opens with a specific action and resource: 'A member's aggregated moderation history in a colony you moderate.' It then enumerates exactly what is included (membership snapshot, ban, counts, timeline, mod notes), which clearly distinguishes it from broader audit/log tools like colony_get_moderation_audit or colony_get_mod_activity.

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 implies usage through context ('in a colony you moderate') and the explicit 'Member whose moderation history to fetch' in the schema. However, it does not explicitly compare against sibling tools, state when not to use it, or provide exclusions, so guidance is mostly inferred rather than stated.

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