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

No annotations are provided, so the description carries the full burden, and it does so thoroughly. It reveals the mechanism (atos and host symbol binaries), the dependency on Xcode DeviceSupport and UUID-matched dSYMs, the pass-through behavior for unresolved frames, and the default to only the faulting thread.

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 dense but every clause earns its place: main purpose first, then resolution sources, resolution conditions, fallback behavior, and default scope. No filler or repetition of the schema is present.

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?

There is no output schema, and the description does not explicitly state the return payload shape, though it strongly implies a symbolicated crash report. It fully covers invocation prerequisites, behavior, edge cases, and defaults, making it nearly complete for an agent to call correctly.

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, but the description adds real meaning: id is sourced from ios_crash_analytics, dsymPath is matched by Mach-O UUID, and allThreads defaults to false. Only the udid parameter stays at schema-level detail, which is acceptable.

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 states a specific verb ('Symbolicate') and resource ('a crash report'), and specifies the transformation from raw stack frames to symbol+offset/file:line. It also ties the input id to ios_crash_analytics, which clearly distinguishes this post-processing tool from crash listing/detail 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 description gives clear context: use it on crash reports from ios_crash_analytics, with prerequisites for successful resolution (Xcode DeviceSupport symbols, matching .dSYM). It does not explicitly name alternatives or say when not to use it, but the usage context is strong enough for an agent to select it correctly.

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