failure_notifications_digest

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

No annotations are present, so the description bears full responsibility for behavioral disclosure. It implies a read-only operation ('build a digest') but does not confirm safety, mention side effects, authentication needs, or rate limits. The minimal description leaves the agent uncertain about underlying behavior.

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 a single, front-loaded sentence that conveys the core action, resource, and purpose with zero wasted words. It is optimally concise.

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 output schema, the description should explain what the digest includes (e.g., format, fields). It does not mention limitations (e.g., 50 max failures) or how results are returned. For a tool that aggregates data, this leaves a significant gap.

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 each parameter is already documented. The description does not add new meaning beyond the schema (e.g., it does not explain how 'interval_hours' or 'limit' affect digest content). Baseline score of 3 applies.

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 clearly states the verb 'build', resource 'digest of recent failures', and purpose 'for alerting and triage'. It distinguishes from sibling tools like 'get_failed_runs' by emphasizing deduplication and summarization, though it does not explicitly differentiate.

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?

No guidance is provided on when to use this tool versus alternatives such as 'get_failed_runs', 'summarize_failure', or 'detect_flaky_tests'. There is no mention of prerequisites (e.g., CI runs must exist) or exclusions.

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