play_get_error_reports

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

No annotations are provided, so the description carries the behavioral disclosure burden. 'Fetch' clearly implies a read-only operation, and 'cleaned de-obfuscated stack traces' conveys a transformation behavior beyond the schema. Still, it does not disclose authentication expectations, pagination behavior, error handling, or whether the operation has any side effects, leaving some transparency gaps.

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 core sentence is compact and front-loaded, immediately stating the resource and purpose. The bracketed '[Atomic Error Reports & Stack Traces]' prefix is somewhat redundant jargon but does not bloat the description. Overall, it is appropriately sized with no wasted sentences.

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 tool with five parameters, no annotations, and no output schema, the description covers the main purpose and return content but leaves some context implicit. It does not explain when to prefer this over play_get_raw_error_reports, nor does it describe pagination or the meaning of 'sample reports' beyond the schema. It is adequate but not fully complete.

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 100%, so the baseline is 3. The description adds only minimal semantic value beyond the schema by restating that issue_id can be an ID or resource name; it does not enrich the meaning of page_size, page_token, package_name, or credentials_path.

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 uses a specific verb ('Fetch') and names concrete resources ('detailed multi-device sample reports and cleaned de-obfuscated stack traces'). It also scopes the operation to 'a given error issue ID or resource name,' which clearly differentiates it from search-oriented siblings like play_search_error_issues and from play_get_raw_error_reports via the 'cleaned de-obfuscated' qualifier.

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 implies when to use the tool: when you already have an error issue ID or resource name and want detailed reports/traces. However, it does not explicitly state when not to use it or mention alternatives such as play_get_raw_error_reports for raw traces or play_search_error_issues for discovery, so the usage guidance remains implicit rather than explicit.

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