compare_gearCompare 2-3 gear items side-by-side with specs, pros/cons, verdicts, and comparison summary.
Supports lookup by unique_id with slug fallback. Use search_gear first if the user hasn't named specific products.

Annotations already indicate readOnlyHint and non-destructive behavior. The description adds the return content (specs, pros/cons, verdicts, comparison summary) and the lookup behavior (unique_id with slug fallback), providing useful context beyond the structured annotations. No contradictions.
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?
Two sentences, front-loaded with the core purpose, and no wasted words. The first sentence states what it does and what it returns; the second adds usage guidance and identifier specifics. Highly 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?
Given the tool's simplicity (1 parameter, clear schema, annotations) and presence of an output schema, the description is complete. It covers purpose, usage context, and identifier behavior, and the guidance to use search_gear first fills an important contextual 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 description coverage is 100%, with the gear_ids parameter already described as 'List of 2-3 gear item identifiers (unique_id or slug)'. The description repeats the 2-3 limit and mentions slug fallback, but adds no new semantics beyond what the schema provides. Baseline 3 is appropriate.
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 tool's purpose: 'Compare 2-3 gear items side-by-side with specs, pros/cons, verdicts, and comparison summary.' It uses a specific verb ('compare'), identifies the resource ('gear items'), and differentiates from siblings like search_gear by focusing on side-by-side comparison.
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?
Explicit guidance is provided: 'Use search_gear first if the user hasn't named specific products.' This tells the agent when to use this tool versus the alternative, and the 'supports lookup by unique_id with slug fallback' hints at prerequisite input formats.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Add one secure layer between your agents and this server.
Most tools have clearly distinct purposes (search, details, availability, weather, etc.), but build_packing_list and get_gear_for_campground both deal with gear recommendations, and check_safety overlaps with the safety section in get_campground_details. However, the descriptions are detailed enough for an agent to choose correctly.
Tool names follow a consistent verb_noun pattern (build_, calculate_, check_, compare_, find_, get_, prepare_, search_) with the exception of health_check, which reverses the order and breaks the pattern. This is a minor deviation.
13 tools is well-scoped for a comprehensive outdoor trip planning server, covering search, details, availability, weather, safety, gear, and reservations without being excessive or sparse.
The server provides end-to-end coverage for planning a camping trip: search and filter campgrounds, get rich details, check availability, prepare reservations, evaluate safety, weather, drive times, gear recommendations, and packing lists. The only missing capability (direct booking) is intentionally excluded due to operator restrictions.
