List coffees

list_beans
Read-onlyIdempotent

List the coffees registered for the account, with status filter. Each coffee carries its bags[] (every purchase, with its own freshness and grams left) and current_bag_id; the row's top-level roast_date, state, grams_remaining and age fields are the current bag's. The id on each row is the number this account knows that coffee by, counting from 1 — safe to show, and what other tools expect back; bag ids are a separate series.

TDQS

A3.7/5.0
Behavior4/5

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

Annotations already cover the read-only/idempotent/destructive safety profile, so the bar is lower, yet the description adds real un-annotated context: bag nesting, that top-level roast_date/state/grams_remaining/age belong to the current bag, and that row `id` is an account-local numbering distinct from bag ids. It stops short of describing pagination or ordering.

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?

Front-loaded with purpose, then dense but useful data-shape clarifications. No filler sentences, though the middle sentence packs several field relationships that could be marginally tighter.

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?

With an output schema present the description need not explain returns, and rich annotations cover safety; the remaining ambiguity it resolves (id vs bag id series) is the one an agent would plausibly get wrong. Minor gaps: no pagination/ordering or archived-vs-all behavior detail.

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 coverage is 100% and the single enum parameter already documents its values and default, so the schema does the heavy lifting. The description's mention of the status filter adds no syntax or meaning beyond the enum.

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?

Specific verb+resource: 'List the coffees registered for the account', clearly separable from sibling list_* tools (list_shots, list_grinders, list_recipes). The status-filter scoping is stated up front.

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?

No when-to-use, when-not, or alternative routing is given. The description never says whether this is the read path before update_bean/register_bag/merge_beans, nor when an agent should prefer this over searching shots. Only the implicit 'list to find ids' is conveyed.

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