The Cure Protocol

get_batch_signals

Read-only

USE WHEN you want to orient on the whole platform in one call, or you are rate-limit sensitive: returns the MIND, Hope and Trends signals together and costs ONE rate-limit slot instead of three. Each signal arrives as its own sub-envelope, so a single upstream failure degrades that one section instead of failing the call — check each sub-envelope before relying on it. NEXT: drill into whichever signal mattered, or into search_world_trials for trial-level evidence.

A4.7/5.0

Behavior5/5

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

Goes well beyond the readOnlyHint/openWorldHint annotations: it discloses the cost model (one rate-limit slot instead of three) and the partial-failure semantics (each signal is its own sub-envelope, one upstream failure degrades only that section), plus the instruction to check sub-envelopes before relying on them. That is exactly the operational context annotations cannot convey.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Front-loaded with the trigger condition, then the behavior, then the next action — three sentences with no filler, each carrying a distinct piece of information an agent needs.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Output schema exists, so return shapes needn't be restated, yet the description still adds the crucial detail that results arrive as separate sub-envelopes with independent degradation. Combined with the routing hint, nothing an agent needs to invoke this correctly is missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100% and every parameter is already documented as 'Forwarded to the mind/trends/every signal', so the schema carries the semantics. The description mentions composing signals but adds no syntax or default guidance (e.g. the 'mind,hope,trends' default) beyond what the schema provides, which is the baseline 3 case.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource set (returns MIND, Hope and Trends signals together) and frames the tool's role as a batch composer over the three singleton signal tools in the sibling list. An agent can distinguish it from get_mind_signal / get_hope_signal / get_trends_signal without opening any schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Opens with an explicit 'USE WHEN' clause (orienting on the whole platform, or rate-limit sensitivity) and closes with a 'NEXT' routing clause toward the individual signals or search_world_trials for trial-level evidence. Both the selection condition and the follow-up path are spelled out.

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