performance-profiling SKILL.md skillA
performance-profiling from nahid-sparktales/agent-dispatcher is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add nahid-sparktales/agent-dispatcher/performance-profiling@git:20260919.a0d4f55Pins git:20260919.a0d4f55 in mdr.lock. Pin the fingerprint instead.

Find where the time actually goes before changing anything — define the metric and workload, build a repeatable baseline with its spread, profile on the right axis, confirm the suspected hotspot by removing its work, then re-measure under identical conditions. Use when something is slow, when an optimization is about to be written from a hunch, or when a speedup is being claimed without comparable numbers. Not for reading code to guess what is expensive, not for micro-tuning with no measured…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Performance profiling The function that looks expensive and the function that is expensive are two different populations with a modest overlap. Every optimization written before a profile is a guess with a diff attached. ## When this fires - Something is measurably slow, or a latency, memory or throughput target is being missed. - An optimization is about to be written on the strength of how the code reads. - A speedup is being reported without a baseline, a spread, or comparable conditions. It does not fire for correctness work, and it does not fire for a change whose only justification is that a faster construct exists — a faster loop inside 2% of the runtime is not an improvement, it is churn. ## Procedure 1. **Define the metric and the workload.** "Slow" is not a metric. Pick one: p95 latency of this request under this load, peak resident memory, time to first byte, wall-clock of this job, rows per second. Say which environment, which data, and what would count as good enough. 2. **Reproduce the slowness in a harness you can run repeatedly**, with representative data. …

How to install
mdr add nahid-sparktales/agent-dispatcher/performance-profiling@sha256:f8024c9061325c6eThe line at the top of this page pins the label git:20260919.a0d4f55, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
