codespine

Benchmark a program in a controlled environment and attribute the cost with the code graph. Use when asked to profile under a CPU/memory cap, measure server capacity ("how many requests per second before p99/latency breaks an SLO"), decide "when do I need more servers", find where runtime is spent under load, or run a workload in a constrained "one box" container. Two modes: cpu-profile (where the time goes) and loadtest (how much load it takes). Requires the codespine CLI; Docker is optional (falls back to running on the host).

Query a TypeScript codebase as a knowledge graph to answer impact, caller, dependency, and dead-code questions. Use this instead of grep/glob for "who calls X", "what breaks if I change X" (blast radius), "is X dead code", "what references this type", and "what is X connected to". Requires the codespine CLI and a built graph database.
