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

No annotations are provided, so the description carries the full disclosure burden. It does well on the return contract — listing install instructions, an install recipe with its status, access level with riskLevel/riskReasons, and an explicit caveat that risk is 'not a code quality rating' — but says nothing about failure behavior for a bad slug/section, response size, or language fallback, and the read-only nature is only implied by 'Read'.

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 intent is front-loaded with 'Read one catalog card', which is good, but the following sentence is a run-on that nests the risk-scale explanation mid-list ('what the tool adds to the agent, low minimal, medium extended, high broad'). The content earns its place; the packaging is dense to the point of being hard to parse in one pass.

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?

With no output schema, the description must explain return values and it largely does — install instructions, recipe plus status, risk fields with scale semantics, and limitations. The remaining gap is the undocumented lang parameter and silent behavior on unknown section/slug, which matters for a two-required-param lookup tool.

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 the description must supply all parameter meaning. It fully enumerates the six valid section values, which compensates for the untyped string, but slug is only obliquely implied by 'one catalog card' and the lang parameter (ru/en, defaulting to ru) is never mentioned at all — leaving a third of the parameters undocumented anywhere.

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 verb+resource pair is specific: 'Read one catalog card' with enumerated payload (install instructions, machine-readable install recipe, access level, limitations), and the section vocabulary (skills, mcp, cli, plugins, workflows, prompts) frames the domain. It differentiates from plan_install by routing step-by-step installs there, but says nothing about search_entries or list_categories, so the boundary with sibling retrieval tools is only partly drawn.

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 clear: this is the single-entry read, and one explicit alternative is named — call plan_install for step-by-step install in a specific agent. What is missing is the negative case: nothing tells the agent to prefer search_entries or list_categories when it does not already know a slug, which is the most likely misuse of this tool.

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