ClimbCast

Search covered objectives

search_objectives

Read-onlyIdempotent

Searches the public coverage catalog by name or alias, with optional region and activity filters. Coverage follows the current public scope. Region filters include WA, OR, and BC. Results list each objective's slug and route IDs with their activities, which the other tools take as inputs. An optional area input limits results to the objectives the coverage directory lists under that area. Query and area can be combined, and at least one of them is needed. A query that names an area or a reviewed place name lists that area's objectives, marked by matchedBy, after any objectives matched by name. Informational only.

A4/5.0

Behavior4/5

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

Annotations already declare readOnly/idempotent/non-destructive, so the description earns credit for adding real behavior: coverage follows the current public scope, results carry slug and route IDs consumed by other tools, matchedBy marks area/place-name matches which are ranked after name matches, and it is informational only. This is substantive disclosure beyond the safety annotations.

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

Conciseness3/5

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

Front-loaded with the core purpose, which is good, but several sentences duplicate schema text almost verbatim ('Region filters include WA, OR, and BC', 'An optional area input limits results to the objectives the coverage directory lists under that area'). Those lines do not earn their place against a 100%-covered schema.

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

Completeness4/5

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

With an output schema present, return-value detail is not required, and the description still usefully notes what results contain (slug, route IDs, activities) and the matchedBy ranking. Combined with full schema coverage and annotations, the definition is complete enough to invoke correctly, with only minor redundancy.

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%, so the schema already documents every parameter including region examples, enum values, and the query/area requirement. The description largely restates this (region codes WA/OR/BC, area limiting results), adding little syntax or format meaning beyond the schema, so the baseline 3 applies.

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?

Specific verb and resource ('Searches the public coverage catalog') plus scope qualifiers (name, alias, region, activity). It clearly distinguishes itself from siblings like list_areas and get_objective_conditions by describing the catalog-search role and noting its outputs feed other tools.

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

Usage Guidelines4/5

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

States the key precondition ('at least one of query and area is needed') and that the two can be combined, and points at list_areas as the source of area slugs. It does not explicitly contrast when to use this versus the sibling get_* tools, so it stops short of a full routing guide.

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