Get Standard Detail

get_tech

Read-onlyIdempotent

Purpose: fetch one rCB technical standard or process by entity ID or keyword - ASTM D36 series (D8178/D8466/D8474...), Chinese GB/T, HG/T, continuous pyrolysis, sCB - with scope, core indicators, status and source link. Guidelines: pass id (e.g. rcb-tech-001) or name keyword ('D8178','pyrolysis','GB/T 40009'); use when an Agent needs the governing standard behind a parameter or certification claim. Limits: metadata + source link only - not full standard text (copyright); verify currency on the official standards platform before compliance use. Ex: 'ASTM D8178 scope', 'rCB national standard GB'.

A4.7/5.0

Behavior5/5

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

Annotations already mark the tool as read-only and idempotent, and the description adds meaningful behavioral limits: it returns metadata and source link only, not full standard text due to copyright, and warns to verify currency before compliance use. This contextualizes expectations beyond the structured annotation fields.

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

Conciseness5/5

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

The description uses labeled sections (Purpose, Guidelines, Limits, Ex) with the core purpose front-loaded. Every sentence carries practical information, and the examples are compact yet illustrative.

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

Completeness5/5

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

For a read-only lookup tool with a rich input schema, existing output schema, and strong annotations, the description fully covers purpose, parameter selection, limitations, and usage context. An agent has everything needed to decide whether to call it and how to invoke it correctly.

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?

The schema already covers all four parameters in detail, establishing a baseline of 3. The description adds value by giving concrete id format ('rcb-tech-001'), keyword examples ('D8178', 'pyrolysis', 'GB/T 40009'), and clarifying the id-or-name relationship, which helps agents pick the right parameter.

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?

Description opens with a specific verb and resource: 'fetch one rCB technical standard or process by entity ID or keyword'. It enumerates the covered standard families and the returned content (scope, core indicators, status, source link), making the tool's job unmistakable and distinct from sibling getters.

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

Usage Guidelines4/5

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

Explicitly states when to use the tool: 'when an Agent needs the governing standard behind a parameter or certification claim' and gives concrete parameter guidance with examples. It does not mention when not to use it or name query_techs as an alternative, so it falls just short of full routing guidance.

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