A4/5.0
Behavior5/5

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

Annotations already establish readOnly, idempotent, openWorld, and non-destructive, but the description goes well beyond them: it discloses null stock IV/VRP values, shared market context fields, the lack of chart histories, unvalidated evidence, non-forecast signal semantics, and the possibility of an open session. This is exactly the behavioral context an agent needs before relying on the output.

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 return content is front-loaded, followed by caveats and limitations; every sentence carries non-trivial information. It is semicolon-dense and a little hard to scan, but not padded with filler.

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?

Given a single required parameter, full schema coverage, output schema, and rich annotations, the description is complete enough to call and interpret the tool. It covers nulls, shared context, evidence limits, and signal interpretation, with no material omissions for a read-only indicator fetch.

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?

The single ticker parameter has 100% schema description coverage, including pattern, case-insensitivity, length, allowed characters, and examples. The description adds only 'one Yahoo Finance symbol,' which is already implied, so baseline 3 is appropriate.

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 states a specific verb and resource: return latest factor and daily/weekly TD Sequential readings for one Yahoo Finance symbol. The scope 'for one Yahoo Finance symbol' distinguishes it from a market-wide tool, but it never names the sibling get_market_indicators, so an agent must infer the boundary.

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?

Usage is implied by 'for one Yahoo Finance symbol' and by the note that it reuses /api/market/indicators?ticker=. There is no explicit when-to-use or when-not-to-use guidance and no named alternative, leaving sibling selection to inference.

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