branch-prediction-and-speculation SKILL.md skillA
branch-prediction-and-speculation from outlinedriven/outline-driven-development is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add outlinedriven/outline-driven-development/branch-prediction-and-speculation@git:20260905.fd53e99Pins git:20260905.fd53e99 in mdr.lock. Pin the fingerprint instead.

Use when explaining branch predictors, mispredict penalties, speculative execution, Spectre or Meltdown mitigations, or branchless code. Not for pipeline stage theory: use cpu-pipelines-and-hazards.
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
# Branch prediction and speculation ## Contract | Field | Bound contract | |---|---| | Trigger | Branchy hot code underperforms, a `likely` or branchless refactor needs judgment, a kernel mitigation such as retpoline or KPTI needs explaining, or code branches on secret data. | | Authority | Read-only. The skill runs `perf stat` on a user-named binary, reads sysfs, and answers in chat. Nothing on disk changes, so there is nothing to roll back. No remote mutation. | | Side effect | Chat output only. `perf stat` writes counters to stdout. | | Done | The answer names the branch that mispredicts or the speculation path that leaks, gives a measured `branch-misses` count where a binary exists, and states the fix with the condition under which it helps. | ## Inputs - Code or hot loop (required): the source or disassembly around the branch in question. - Binary and workload (optional): needed for a measured verdict. Without them the answer is a hypothesis. - Threat model (optional): whether the question is performance only or also side-channel safety. ## Procedure …

How to install
mdr add outlinedriven/outline-driven-development/branch-prediction-and-speculation@sha256:f01cc380134dd446The line at the top of this page pins the label git:20260905.fd53e99, 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.
