Institution Rating Detail

institution_rating_detail
Read-onlyIdempotent

Retrieve historical institution ratings and target price history for a given security symbol. Use this tool to analyze analyst sentiment and price target trends.

Instructions

Get detailed historical institution ratings and target price history.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
_jqNoOptional jq filter (jaq syntax) applied to this tool's JSON response before it is returned; it never changes the upstream request. One output is returned as-is, several as a JSON array, none as []. Module imports and the `env`/`debug`/`stderr` builtins are unavailable. Example: .data | map({symbol}). Omit for the full response.
symbolYesSecurity symbol, e.g. "700.HK". Use the canonical form — a padded code like "00700.HK" returns an empty record, not an error.

TDQS

C2.9/5.0
Behavior2/5

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, covering the safety profile. The description adds no additional behavioral disclosure such as rate limits, pagination, error behavior, or the canonical symbol requirement, which is only in the parameter description.

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?

The description is a single concise sentence with no superfluous words. It front-loads the action and resource effectively. It could be slightly more informative about the 'detail' aspect, but it remains appropriately sized.

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?

The description is adequate for a simple read-only tool with one required parameter and no output schema. However, it does not differentiate from closely named siblings like institution_rating_history, leaving ambiguity about when to choose this tool. The canonical symbol caveat is covered in the schema, so it does not need to be in the description.

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% for both parameters (symbol and _jq), so the schema already provides complete parameter documentation. The tool description adds no extra meaning beyond what is in the schema, so baseline 3 applies.

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?

The description clearly states a specific action and resource: 'Get detailed historical institution ratings and target price history.' It is clear but does not explicitly distinguish itself from sibling tools like institution_rating_history or institution_rating, relying on the 'detail' in the name for differentiation.

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

Usage Guidelines2/5

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

The description provides no guidance on when to use this tool versus alternatives. It does not mention conditions, prerequisites, or exclusions. It is purely a purpose statement without any usage context.

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