exa-load-scale
Implement Exa load testing, capacity planning, and scaling strategies. Use when running performance tests, planning capacity for Exa integrations, or designing high-throughput search architectures. Trigger with phrases like "exa load test", "exa scale", "exa capacity", "exa k6", "exa benchmark", "exa throughput".

Discovery
89%Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.
This is a well-structured skill description with strong completeness and distinctiveness. It explicitly provides 'Use when' and 'Trigger with' clauses, and the Exa-specific focus makes it clearly distinguishable. The main weakness is that the capability descriptions could be more concrete—listing specific actions like configuring k6 scripts, analyzing rate limits, or generating benchmark reports rather than high-level categories.
Suggestions
Add more specific concrete actions beyond high-level categories, e.g., 'configure k6 test scripts, analyze rate limit headers, generate throughput reports, optimize batch request patterns' to improve specificity.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Names the domain (Exa load testing, capacity planning, scaling) and some actions (running performance tests, planning capacity, designing architectures), but the actions are somewhat high-level rather than listing multiple concrete specific operations like 'configure k6 scripts, analyze throughput metrics, set rate limits'. | 2 / 3 |
Completeness | Clearly answers both 'what' (implement load testing, capacity planning, scaling strategies) and 'when' (explicit 'Use when' clause plus explicit 'Trigger with phrases' listing). Both components are well-articulated. | 3 / 3 |
Trigger Term Quality | Excellent coverage of natural trigger terms including 'exa load test', 'exa scale', 'exa capacity', 'exa k6', 'exa benchmark', 'exa throughput', plus phrases like 'performance tests', 'capacity planning', and 'high-throughput search architectures'. These are terms users would naturally use. | 3 / 3 |
Distinctiveness Conflict Risk | Highly distinctive due to the specific 'Exa' product focus combined with load testing/capacity planning niche. The trigger terms are all prefixed with 'exa', making conflicts with generic performance testing or other API skills unlikely. | 3 / 3 |

Implementation
64%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is a solid, highly actionable skill with complete, executable code examples covering load testing, queuing, caching, and capacity planning for Exa integrations. Its main weaknesses are the lack of validation checkpoints in the workflow (important for load testing scenarios) and the monolithic structure that could benefit from splitting code into referenced files. The capacity reference table and error handling table are practical additions, though some content could be tightened.
Suggestions
Add explicit validation checkpoints to the workflow, e.g., 'Verify your test API key works with a single request before running the full load test' and 'Check for 429 errors after Step 1 before proceeding to stress testing.'
Extract the k6 script and TypeScript implementations into bundle files (e.g., exa-load-test.js, throughput-maximizer.ts) and reference them from SKILL.md to improve progressive disclosure.
Collapse the capacity reference table's redundant 'Max Throughput' column since all values are identical, and instead state the 10 QPS limit once with latency differences highlighted.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill is mostly efficient with good use of tables and code, but includes some unnecessary elements like the 'Prerequisites' section (Claude knows what k6 and Redis are), and the capacity reference table has redundant 'Max Throughput' column since every row is identical at 10 req/s. The benchmark results template and error handling table add value but could be slightly tighter. | 2 / 3 |
Actionability | Excellent executable code throughout — the k6 load test script is complete and runnable, the TypeScript queue implementation uses real libraries with correct APIs, the caching layer is copy-paste ready, and the capacity calculator is fully functional with example output. Bash commands for running tests are included. | 3 / 3 |
Workflow Clarity | Steps are clearly numbered and sequenced (load test → queue → cache → capacity planning), but there are no explicit validation checkpoints or feedback loops. For load testing (a potentially costly operation against rate-limited APIs), there should be verification steps like 'confirm test environment key is set' or 'validate baseline with a single request before ramping up.' The error handling table partially compensates but is reactive rather than integrated into the workflow. | 2 / 3 |
Progressive Disclosure | The content is well-structured with clear sections and a logical flow, but it's quite long (~180 lines of substantive content) with no bundle files to offload detail. The k6 test script, queue implementation, caching layer, and capacity calculator could each be separate referenced files. The single reference to 'exa-reliability-patterns' at the end is good but the main body is monolithic. | 2 / 3 |
