get_semantic_conventions

Retrieve OpenTelemetry semantic conventions by category, with optional file count limit, to access standardized observability definitions.

Instructions

Get OpenTelemetry semantic conventions from the semantic-conventions repository

Returns semantic conventions from the OpenTelemetry semantic-conventions repository as markdown documentation files.

Args: category: Optional category filter (e.g., "http", "database", "messaging") count: Maximum number of files to retrieve (default: 50)

Behavior3/5

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

No annotations provided, so description carries full burden. It reveals that the tool returns markdown documentation files, which is helpful. However, it does not disclose other behaviors like readability, authentication needs, or effects of invalid parameters. Acceptable but could be more transparent.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Three sentences with slight redundancy (first two both describe returning conventions). Could be more concise by merging, but not overly verbose. Front-loaded with purpose.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Covers purpose and parameters adequately for a retrieval tool with two optional params. Lacks details on return value structure (list of files, content?) and error handling. With no output schema, more specificity would improve completeness.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

With 0% schema description coverage, the description compensates well by explaining both parameters: 'category' as optional filter, 'count' as maximum number of files with default 50. This adds meaningful context beyond the schema's type/default fields.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

Clearly states verb 'Get' and resource 'OpenTelemetry semantic conventions' from the repository, and specifies output format as 'markdown documentation files'. While not extremely detailed, it effectively distinguishes from sibling tools focused on instrumentation scoring and docs by language.

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

Usage Guidelines3/5

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

Description implies use by listing optional parameters (category, count), but no explicit guidance on when to use or avoid this tool vs alternatives. Sibling tools cover different topics, so context is somewhat clear but lacks explicit usage direction.

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