get_provider_capabilities

Read-only

What one provider publishes, counted by artifact type, with the agent dimensions it satisfies. Free — it is a fact about their own public surface. NOTE: this is artifact counts, NOT business capabilities — for what the vendor lets a business DO, call get_provider_business_capabilities. Priced B1 (single-entity synthesis) — $0.01 per call under pay-as-you-go; included in Understanding and Influence. See apis://prices.

A4.3/5.0
Behavior4/5

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

Annotations already cover readOnlyHint and openWorldHint, so safety is known. The description adds genuinely new behavioral context: the response shape (counts by artifact type + agent dimensions), the 'free' status, and concrete cost/pricing details ('$0.01 per call', tier inclusions, apis://prices reference). Strong added value; only slight gap is it doesn't mention any pagination or staleness traits.

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 the core purpose, then a clarifying contrast, then pricing. Dense with a NOTE and a price reference but every sentence earns its place; the pricing sentence is somewhat heavy for a tool description.

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 no output schema, the description compensates by describing the return content (counts by artifact type plus satisfied agent dimensions). Combined with the cost model and sibling routing, an agent has enough to call it correctly; a minor gap remains around response structure specifics.

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 100%, so both parameters (slug and optional context) are already fully documented in the schema. The description adds no further parameter semantics beyond what the schema provides, so the baseline 3 is appropriate.

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 ('what one provider publishes, counted by artifact type, with the agent dimensions it satisfies') and explicitly distinguishes itself from the sibling get_provider_business_capabilities. An agent can select it without ambiguity.

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

Usage Guidelines5/5

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

Explicitly says this is artifact counts, NOT business capabilities, and names the alternative tool and its condition of use. The when-to-use and when-not-to-use are both spelled out.

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