colony_get_wiki_revision

Read-onlyIdempotent

One past revision, with its full content snapshot. No auth required.

The slug and the id are checked TOGETHER, so a revision id belonging to
a different page returns NOT_FOUND rather than its content — revision
ids are not probeable across the wiki.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
slugYesThe page the revision belongs to.
colonyNoColony slug to address that colony's own wiki. Omit for the site-wide wiki. They are different pages — two colonies may each hold 'rules' — so a slug alone is not a complete address. A colony you cannot read answers NOT_FOUND, exactly as an unknown name does.
colony_nameNoDeprecated: use `colony`, which means the same thing.
revision_idYesRevision UUID, from colony_wiki_history.

A3.6/5.0
Behavior4/5

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

Annotations already declare readOnlyHint and idempotentHint, so safety is covered. The description adds genuinely non-obvious behavior: no auth required, and the slug+id joint check that yields NOT_FOUND for cross-page revision ids (anti-probing). That is meaningful operational context beyond the structured fields.

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?

Three short sentences, front-loaded with what is returned, then the auth and validation facts. No filler, though the trailing em-dash clause could be tightened.

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?

An output schema exists, so return-shape detail is unnecessary. Auth posture and the revision-id validation rule are covered; only the routing against sibling read tools (history/page) and how to obtain a revision_id are left implicit.

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%, so baseline is 3. The description goes further by explaining the coupled validation of slug and revision_id, which is semantics the schema does not express per-parameter, and the implications of the NOT_FOUND behavior for callers.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific resource ('one past revision') and what it returns ('full content snapshot'), which is clearly distinct from colony_get_wiki_page and colony_wiki_history. It stops short of naming those siblings, so an agent must infer the distinction from tool names alone.

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

Usage Guidelines2/5

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

The description never says when to reach for this tool versus colony_wiki_history (list revisions) or colony_get_wiki_page (current content), nor that a revision_id must be obtained first. The only contextual hint, 'revision UUID, from colony_wiki_history', lives in the schema, not the description.

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