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

With no annotations provided, the description must disclose behavioral traits like safety (read-only vs. mutation) and side effects. It does not state whether the tool is read-only, what resources it accesses, or any rate limits. The only behavioral hint is the token_id parameter in the schema (payment required if omitted), which is not mentioned in the description. Thus, the description adds little transparency beyond the schema.

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?

The description is a single dense sentence that front-loads the primary purpose and includes the key outputs. It is concise and free of fluff, though it is packed with technical jargon. It earns its place but could be slightly more readable by breaking into two sentences.

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 the tool has 9 parameters and no output schema, the description should explain return values. It lists several metrics (coverage, confidence intervals, Winkler scores, regime diagnostics), which gives a partial picture. However, it does not describe the overall structure of the response, error conditions, or the walk-forward methodology in detail. It is adequate but not complete for such a complex tool.

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 coverage is 100%, so the baseline is 3. The description does add some meaning by mentioning 'independent resolved anchors' and the key configuration parameters, but it does not enrich the understanding of parameters beyond what the schema already describes. It essentially repeats the parameter names without adding new semantic details.

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 clearly states the tool's function: it walks forward a candle configuration (symbol, interval, q, f) over resolved anchors and compares analogue/volatility-scaled bands against a baseline. It names the key parameters and specific analysis outputs (coverage, Winkler scores, regime diagnostics), distinguishing it from siblings like get_track_record or get_pattern_metrics.

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?

No guidance is provided on when to use this tool versus alternatives. The description does not mention any exclusions, prerequisites, or scenarios for which this tool is appropriate. It simply describes what it does without contextualizing its use relative to sibling tools.

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