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

With no annotations, the description carries the burden and does well: it discloses the data source (TradingView screener), freshness ('Live'), latency (~0.2s), and implicit read-only snapshot semantics, plus a hard cap of 20 symbols and a default of top 12 BINANCE majors. It stops short of noting auth/rate-limit behavior or what happens to invalid tickers.

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?

Purpose and output surface are front-loaded, and the density is high with little waste. The trailing 'Use for TA' fragment breaks the structure and should be completed or deleted.

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?

For a zero-parameter read tool with no output schema, the description is substantially complete: it lists return fields, data source, latency, and default behavior. The unresolved gap is that the only configurable dimension (symbols) is described in query-string form while the input schema declares no properties at all, leaving the agent unsure whether it can pass 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?

The schema is empty, so the baseline is 4, and the description supplies genuinely useful semantics for the symbols input: max 20, default top-12 majors, BINANCE pairs, and acceptance of both bare tickers (HYPE) and full symbols (BINANCE:HYPEUSDT). The caveat is that no such property exists in the schema (additionalProperties: false), so the guidance is not reliably actionable.

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?

Opens with a specific resource and verb substitute: 'TradingView technical-analysis snapshot for crypto', then enumerates exactly what is returned (per-timeframe ratings, RSI, ATR/ATR%, 24h change, volume, 52-week range, composite bias, trend-alignment tag). An agent can tell precisely what this tool produces versus sentiment, funding, or trade-plan siblings.

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 only usage signal is the truncated fragment 'Use for TA', which reads as cut off mid-sentence and names no alternatives, no exclusions, and no prerequisites. There is no guidance on when to prefer this over the sibling TA-adjacent tools such as akari_ta or akari_confluence.

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