get_terraform_alias

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

Annotations already declare readOnly, idempotent, non-destructive and open-world, so the safety profile is covered. The description adds real value beyond them by disclosing that some Community-edition routes return 404 or empty lists depending on license and permissions, which is exactly the kind of failure-mode context an agent needs before interpreting an empty response.

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

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

Two compact sentences: the operation is front-loaded and the caveat sentence is dense with useful information rather than padding. The lowercase terse opening is slightly under-polished but nothing is wasted.

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

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

For a read-only getter with no output schema, the description should at least hint at what an alias record contains, or how to obtain valid IDs. It covers availability and the endpoint but leaves the returned shape and ID discovery to inference, which is a meaningful gap for an agent calling it cold.

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

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

Schema description coverage is 0%, so all three parameters (project_id, inventory_id, alias_id) are documented only by name and type. The description partially compensates by embedding them in the REST path, which conveys that alias_id is scoped under an inventory under a project, but it adds no format, lookup, or ID-provenance detail.

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

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

The description states a specific verb ('get') and resource ('terraform alias') and the REST path makes clear it retrieves a single alias identified by alias_id, which distinguishes it from list_terraform_aliases and from create/update/delete_terraform_alias. It does not explicitly name those siblings, so it falls short of a 5.

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

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

Usage is only implied by the endpoint shape – fetch one alias by project/inventory/alias ID. The description instead spends its guidance on availability preconditions (edition, license, permissions) rather than telling the agent when to choose this over list_terraform_aliases or get_terraform_state. It never states explicit exclusions or alternatives.

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