Mod changelogs

nexus_get_mod_changelogs

Read-only

Retrieves per-version changelogs for a Nexus Mods mod, newest first, so agents can inspect release history and changes. Use for follow-up after getting a mod overview.

Instructions

Per-version changelogs for a mod, newest first. Narrow follow-up tool: nexus_mod_overview already returns the most recent versions.

A4/5.0

Behavior3/5

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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=true, so the safety profile is covered. The description adds useful ordering context ('newest first') but says nothing about cache behavior or how many entries come back by default beyond what the schema implies.

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?

Two short sentences with zero waste; the ordering and the sibling relationship are both front-loaded. Every clause earns its place.

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?

No output schema exists, so the description must convey return shape; 'per-version changelogs, newest first' adequately does so for a read-only list tool. It could note pagination/volume limits, but nothing critical is missing for correct invocation.

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 75%, with refresh, versions (default 10) and game_domain_name documented in the schema itself. The description adds no parameter-level meaning (no default count, no game-domain note), so it merely hits the baseline for a well-annotated 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?

States a specific verb and resource ('Per-version changelogs for a mod') plus ordering ('newest first'), and explicitly differentiates itself from the sibling nexus_mod_overview. An agent can tell exactly what this returns without opening a schema.

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?

Labels itself a 'narrow follow-up tool' and names the alternative (nexus_mod_overview) that already covers recent versions, implying this is for deeper/older changelog retrieval. The selection condition is strongly implied rather than spelled out as an explicit 'use when X, not Y' rule.

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