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

With no annotations provided, the description carries the transparency burden and does substantial work: it discloses that results are 'computed from real OHLC price data' and that it uses the same engine powering XFINLAB's chart-analysis and ai-analysis pages. It does not mention error behavior or rate limits, but the read-only 'Get' framing plus data-source disclosure is strong for a non-mutating analysis tool.

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?

A single dense sentence with no filler; the resource and scope are front-loaded and the trailing engine-context clause adds credibility. The parenthetical list of market-structure signals is long but informative, making it slightly heavy rather than wasteful.

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?

Given no output schema and no annotations, the description compensates by enumerating the signal categories the tool returns and explicitly bounding the input to one ticker. The schema fills in parameter details. It doesn't describe output structure, but the signal enumeration gives an agent enough to understand what will come back and how to invoke it.

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 100%, so the schema already documents all five parameters and their defaults. The description adds context that the analysis is per-ticker and OHLC-driven, but it doesn't add semantic detail for lang, period, interval, or api_key beyond the schema. Baseline 3 is appropriate.

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 description opens with a specific verb ('Get') and names an unusually specific resource: confluence direction/confidence, trend, MACD, volume, chart patterns, and market-structure signals. It explicitly scopes to 'one ticker', which cleanly differentiates it from the market-level siblings (get_global_market_map, get_sentiment, etc.).

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?

The description implies when to use it by emphasizing single-ticker technical analysis, distinguishing it from sibling tools that cover market maps, feeds, events, and sentiment. It does not state an explicit when-not-to-use or name an alternative, but the 'one ticker' scope provides clear usage context.

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