performance-debugging skillA
performance-debugging is agent-read markdown (skill) from iuliandita/skills: Diagnose a known application's CPU, heap, allocation, lock, and latency regressions with profiles, reproducible baselines, and measured verification..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Performance Debugging Find and verify the cause of an observed performance regression in a known application or service. This skill uses hypotheses, representative workloads, runtime profiles, and before/after measurements; it does not turn a benchmark into a production load test or treat a flame graph as proof without a reproduced symptom. ## When to use - Investigating known application CPU, heap growth, allocation, lock contention, GC, throughput, or latency regressions - Profiling a service, worker, CLI, or library after a reproducible slow path is identified - Comparing a change against a stable baseline and checking for performance regressions - Turning a production observation into a safe local or staging reproduction ## When NOT to use - The broken or slow component is unknown; use **debug-triage** to localize the layer first - Adding standing metrics, traces, logs, alerts, or dashboards; use **observability** - Designing benchmark, load-test, soak-test, or capacity-test infrastructure; use **testing** - Diagnosing database query plans or database engine health; use **databases** …

How to install
mdr add iuliandita/skills/performance-debugging@git:20260920.ebf9a3dmdr add iuliandita/skills/performance-debugging@sha256:efb48a8fec5eb91ePin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
