TradingView-only: EGX overview

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

No annotations are supplied, so the description carries the full burden and discloses almost nothing: 'TradingView-only' flags the upstream source, but there is no word on rate limits, caching, freshness, auth, or expected cost of an overview call. 'Returns: Envelope labelled TRADINGVIEW' is return-shape information that duplicates the existing output schema rather than adding behavioral insight.

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 text is short and front-loads the resource name, which is good. But the second half is a 'Returns' stanza that restates what the output schema already provides, while the parameters that actually need explanation receive zero words — the space is spent in the wrong place.

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?

An output schema exists, so return values need not be explained, and the tool is read-only in nature with no nested objects. Still, with two undocumented parameters, no usage guidance, and no annotations, an agent is left guessing about the arguments and about when this overview beats the many sibling market tools.

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 0% for two parameters, and the description compensates for nothing — it never mentions 'limit' or 'timeframe'. An agent cannot tell whether limit caps rows, symbols, or index entries, or what timeframe values other than the default '1D' are accepted.

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 names a specific resource (Egyptian Exchange overview) and a data source constraint (TradingView-only), so an agent knows roughly what it returns. However there is no verb describing the operation and no differentiation from plausible siblings such as market_snapshot, market_indices, or market_sentiment, so selection relies on the name alone.

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?

There is no when-to-use guidance, no stated preconditions, and no mention of alternatives. The parenthetical 'TradingView-only' hints at a data-source constraint but never says which tool to pick when TradingView data is insufficient or when the user wants a different market region.

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