instantly-performance-tuning
Optimize Instantly.ai API performance with caching, batching, and connection pooling. Use when experiencing slow API responses, implementing caching strategies, or optimizing high-volume lead operations. Trigger with phrases like "instantly performance", "instantly slow", "instantly caching", "instantly batch", "optimize instantly api".

Discovery
100%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-crafted skill description that clearly identifies the specific product (Instantly.ai), lists concrete optimization techniques (caching, batching, connection pooling), and provides explicit trigger guidance with natural user phrases. It uses proper third-person voice and covers both the 'what' and 'when' comprehensively.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists multiple specific concrete actions: caching, batching, and connection pooling. Also mentions specific optimization scenarios like caching strategies and high-volume lead operations. | 3 / 3 |
Completeness | Clearly answers both 'what' (optimize Instantly.ai API performance with caching, batching, and connection pooling) and 'when' (experiencing slow API responses, implementing caching strategies, optimizing high-volume lead operations) with explicit trigger phrases. | 3 / 3 |
Trigger Term Quality | Excellent coverage of natural trigger terms including 'instantly performance', 'instantly slow', 'instantly caching', 'instantly batch', 'optimize instantly api'. These are phrases users would naturally say when experiencing these issues. | 3 / 3 |
Distinctiveness Conflict Risk | Highly distinctive — targets a specific product (Instantly.ai) with specific optimization techniques. The combination of the product name and performance optimization focus makes it very unlikely to conflict with other skills. | 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 TypeScript implementations for each optimization technique. Its main weaknesses are verbosity (large inline code blocks that could be referenced externally) and missing validation/verification steps after applying optimizations. The benchmarks and error handling tables are valuable additions.
Suggestions
Add a verification step after each optimization (e.g., 'Run a test batch of 10 leads to confirm concurrency settings work before processing full dataset')
Consider moving the full class implementations to a separate reference file and keeping only the key patterns/usage examples inline to improve conciseness and progressive disclosure
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill is mostly efficient with executable code examples, but includes some unnecessary commentary (e.g., 'Campaign analytics don't change every second') and the code blocks are quite lengthy. The progress logging and some inline comments could be trimmed. The benchmarks table adds value but the prerequisites section explaining 'understanding of async patterns' is unnecessary for Claude. | 2 / 3 |
Actionability | Every section provides fully executable TypeScript code with concrete implementations — caching class, batch operations with retry logic, async generator pagination, connection pooling, and throttled client. All code is copy-paste ready with specific configuration values and real API paths. | 3 / 3 |
Workflow Clarity | Steps are clearly numbered and sequenced, but there are no explicit validation checkpoints or verification steps. For batch operations (Step 2), there's retry logic but no guidance on verifying the final result or what to do if the failed array is large. Missing a 'verify your optimization is working' step or feedback loop for confirming improvements. | 2 / 3 |
Progressive Disclosure | The content is well-structured with clear sections and tables, but it's quite long (~200 lines of code) and could benefit from splitting detailed implementations into separate reference files. The reference to 'instantly-install-auth' and 'instantly-cost-tuning' shows awareness of cross-referencing, but the main body is monolithic with all implementations inline. | 2 / 3 |
