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

No annotations are present, so the description carries the full disclosure burden. It states the tool is a read ('Read one reviewed venue market'), scopes it to 'reviewed venues', and describes what is returned, but says nothing about quote staleness, caching, auth or permission prerequisites, or failure behavior for unsupported venue/market combinations — meaningful gaps for a pre-trade data source.

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?

Three front-loaded sentences with the core action first, followed by usage and boundaries, then return values. It is slightly dense and repeats 'reviewed' four times, but no sentence is filler.

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 4-parameter read tool with full schema coverage and no output schema, the description supplies the trigger, the scope limits, and a summary of what comes back. Only the relationship among the overlapping venue/market/profile parameters and the freshness of the quote context remain unaddressed.

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 venue, market, venues, and profile_id are already documented, and the enums constrain values. The description adds only contextual framing ('reviewed profile ids', 'market id') and does not clarify how the plural 'venues' array relates to the singular 'venue' parameter or when profile_id is required — the one genuinely ambiguous interaction a caller would want explained.

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 concrete verb and resource — 'Read one reviewed venue market' — and enumerates the payload (pool/market metadata, pinned quote context, venue constraints) plus the supported chains, which distinguishes it from price-only siblings like get_oracle_price. The only softness is the tension between the tool name 'get_market_quote' and the description's emphasis on returning a market record rather than a standalone quote.

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?

It gives both a positive trigger ('Use it before preparing or gating a trade when the agent needs the reviewed profile or market id') and a negative boundary ('Do not use it as execution authorization or for prices outside the reviewed venues'). It does not explicitly name the sibling to use instead for execution or for non-reviewed prices, so routing is implied rather than spelled out.

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