ripwire-perf-target SKILL.md skillA
ripwire-perf-target from redhat-et/ripwire is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add redhat-et/ripwire/ripwire-perf-target@git:20260913.30a5a3cPins git:20260913.30a5a3c in mdr.lock. Pin the fingerprint instead.

A MEASURED performance problem: start from a benchmark, flame graph, perf sample or profiler run, locate the hot symbol the profile names, test structural hypotheses (memory-bound → cache-line data layout). Static metrics are change-risk signals, not runtime heat. Inspect only the symbols the profile names.
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 targeting with ripwire > Nearest neighbours: > • Repo-wide quality/health sweep (not perf-specific) → **ripwire-fresh-eyes** (also uses --hotspots). > • Finding a specific BUG, not a slow path → **ripwire-find-bug**. Trigger: a representative benchmark, flame graph, trace, or profiler has identified a slow operation, file, stack, or symbol and you need to understand where a safe optimization belongs. If you have no measurement yet, create the smallest representative benchmark/profile first; ripwire cannot infer runtime cost from source shape. `<dir>` = repo root. 1. **Pin the measured evidence** — record the workload, baseline, profiler/trace result, and the symbol or subsystem it implicates. Keep the same workload for the after measurement. 2. **Navigate the measured surface** — `ripwire <dir> --for="measured operation or symbol" --detail=3`, then `--callers=SYM`, `--callees=SYM`, or `--around=SYM` as needed. This turns runtime evidence into a bounded source-reading set without pretending the graph measured execution. 3. **Maintenance/change-risk context** — `ripwire <dir> --hotspots --legend=compact` …

How to install
mdr add redhat-et/ripwire/ripwire-perf-target@sha256:29df71d54148c513The line at the top of this page pins the label git:20260913.30a5a3c, 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.
