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

No annotations exist, so the description bears the full burden. It usefully discloses the content categories returned (killzones, FVG windows, spread-danger alerts, swap flags) and implies a read-only informational call. But it omits any statement about access requirements, cost/auth (the '$0.005 USDC on Base' fragment is unexplained), latency, or freshness semantics beyond the word 'live'.

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?

It is a single dense sentence with the core purpose front-loaded, which is good. But the trailing fragment '($0.005 USDC on Base)' is unexplained and arguably does not earn its place, muddying rather than clarifying the sentence.

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?

With no annotations and no output schema, the description should carry the whole load. It enumerates what categories come back but gives no sense of return shape (e.g., whether killzones are objects with start/end times or booleans) or of the cost/auth implication of the USDC note, leaving the agent to guess at invocation context.

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?

There is a single optional parameter with 100% schema description coverage, so the schema already explains the ISO-8601 'at' timestamp and its default. The description's 'live' wording is consistent with that default but adds no extra semantics such as how historical evaluation differs from live evaluation.

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 the exact resource and its sub-components (Asian, London Open, NY Open, London Close killzones, Silver Bullet FVG windows, rollover alerts, triple-swap flags). An agent can tell this is a market-session/time-window lookup, which is distinguishable from siblings like get_cfd_microstructure or calculate_prop_firm_risk. However, it never explicitly contrasts itself with get_cfd_microstructure, which is the nearest conceptual neighbor.

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 statement of when to call this tool versus alternatives, and no sibling is named. The word 'live' hints at real-time monitoring use, but nothing tells the agent when to prefer this over get_cfd_microstructure or when a historical evaluation is appropriate.

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