Instructions

Find top alternatives to a given software tool within the same category, sorted by rating.

Implementation Reference

  • The handler function for 'get_alternatives'. Finds the target tool by slug, then filters all tools to find other tools in the same category, sorted by rating descending, limited by the limit parameter. Returns a formatted text response with the top alternatives.
    async function getAlternatives(args) {
      const { slug, limit = 5 } = args;
      const allTools = await getAllTools();
    
      const target = allTools.find(t => t.slug === slug);
      if (!target) return `Tool with slug "${slug}" not found.`;
    
      const alternatives = allTools
        .filter(t => t.slug !== slug && t.category === target.category)
        .sort((a, b) => (b.rating ?? 0) - (a.rating ?? 0))
        .slice(0, limit);
    
      if (alternatives.length === 0) {
        return `No alternatives found for "${target.name}" in category "${target.categoryName || target.category}".`;
      }
    
      const lines = alternatives.map((t, i) =>
        `${i + 1}. ${t.name} | Rating: ${t.rating ?? 'N/A'}/5 | Free: ${t.freePlan ? 'Yes' : 'No'} | Price: ${formatPrice(t.startingPrice)} | ${toolURL(t.slug)}`
      );
      return `Top alternatives to ${target.name} in ${target.categoryName || target.category}:\n\n${lines.join('\n')}\n\nFull list: ${SITE_BASE}/alternatives/${slug}-alternatives`;
    }
  • The tool definition / input schema for 'get_alternatives'. Defines name, description, and inputSchema with 'slug' (required) and 'limit' (optional, default 5).
    {
      name: 'get_alternatives',
      description: 'Find top alternatives to a given software tool within the same category, sorted by rating.',
      inputSchema: {
        type: 'object',
        properties: {
          slug: { type: 'string', description: 'Slug of the tool to find alternatives for' },
          limit: { type: 'number', description: 'Maximum number of alternatives to return (default: 5)' },
        },
        required: ['slug'],
      },
    },

Behavior2/5

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

No annotations are provided, so the description must cover behavioral traits. It only states the sorting and category constraint, but does not disclose whether the operation is read-only, data freshness, or any limitations. This is insufficient for a tool with no annotations.

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?

Single sentence with 14 words, front-loaded verb, no extraneous information. Every word adds value.

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

Completeness3/5

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

Description explains what the tool does but does not specify the output structure (e.g., what fields are returned in each alternative). Given no output schema, more detail is needed for an agent to correctly interpret the result.

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

Parameters4/5

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

Schema coverage is 100%, but the description adds meaningful context: alternatives are 'top' and sorted by rating within the same category. This goes beyond the parameter descriptions which only define slug and limit.

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?

Description clearly specifies verb (find), resource (alternatives to a given software tool), and constraints (within same category, sorted by rating). This distinguishes it from siblings like get_tool and search_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?

Description clearly indicates when to use: when finding alternatives for a specific tool within the same category. However, it does not explicitly mention when not to use or point to alternatives like compare_tools.

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