get_inventory_tier

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

With no annotations, the description carries the full burden and does disclose the endpoint (GET, implying a safe read), the required authentication scheme (Bearer PERSONAL_OAUTH_TOKEN), and concrete error conditions (403 NOT_AUTHORIZED, 404 NOT_FOUND with the specific missing-entity cause). This is well beyond what the schema provides; only the response shape and any rate-limit behavior are unstated.

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?

Front-loaded with the purpose, then organized into labeled ENDPOINT/ERRORS/AUTHENTICATION blocks. Every block carries actionable information for an agent, though the formatting is more verbose than necessary for a two-parameter lookup.

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 simple GET-by-ID tool with full parameter coverage, the description supplies endpoint, auth, and error semantics. Because there is no output schema and no annotation coverage, it could have described the returned tier fields, which leaves a modest gap.

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 coverage is 100%, so both required parameters (event_id, inventory_tier_id) are already documented in the schema. The description adds no format, type, or sourcing guidance beyond restating the ID-based lookup, so the baseline 3 applies.

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 (Retrieve), resource (Inventory Tier), and scoping qualifier (by ID for an Event), and even explains what the resource is ('controls capacity across multiple tickets. Supports GA holds'). An agent can distinguish it from list_inventory_tiers, create_inventory_tier, and update_inventory_tier without opening the schema.

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?

Implied usage is clear from 'by ID' (a point lookup for a known inventory tier), but the description never states when to use this versus list_inventory_tiers or how to obtain the required IDs. No explicit alternatives or prerequisites are named.

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