identity_get_all_service_definitions

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

Annotations already cover readOnly/idempotent/openWorld, so the value-add here is the access policy table (which roles can call) and the endpoint path. It stops short of describing pagination or return shape for an "get all" tool, which is the notable gap.

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?

The deprecation warning is front-loaded, which is good, but the raw markdown access-policy table is dumped verbatim and the "no analogue" sentence is boilerplate clutter.

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?

An agent learns the operation, its deprecated status, and access roles, but with no output schema and undocumented parameters, it cannot confidently construct the expand/orgLink query.

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?

Two parameters (expand, orgLink) exist at 0% schema description coverage, and the description says nothing about either. The description fails to compensate for the schema's silence on their meaning and format.

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?

States a specific verb and resource ("Get all service definitions") plus the raw endpoint. It does not distinguish itself from near-identical siblings like identity_get_all_by_org_service_definitions or identity_get_paged_service_definition_orgs, so sibling differentiation is missing.

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?

The [DEPRECATED] tag is a real when-not signal — it tells the agent to prefer another tool — but it never names a replacement and the cryptic "no analogue in Tenant Manager" note gives no actionable alternative.

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