fastopt SKILL.md skillA
fastopt from outlinedriven/odin-claude-plugin is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add outlinedriven/odin-claude-plugin/fastopt@git:20260905.4d9e207Pins git:20260905.4d9e207 in mdr.lock. Pin the fingerprint instead.

Use when optimizing suspected hot paths without waiting for benchmarks. Not for estimated-floor optimization: use fastopt-extreme. Not for measured-floor rebuild campaigns: use extremely-optimize.
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
# Fastopt ## Contract | Field | Bound contract | |---|---| | Trigger | User wants to optimize suspected hot paths without waiting for benchmarks, labeling claims as hypotheses. | | Authority | Read-only. No file, VCS, credential, paid, published, deployed, or remote mutation. | | Side effect | Chat output only: hypotheses and benchmark designs before any mutation or performance claim. | | Done | Hypotheses and benchmark designs for suspected hot paths are emitted; no mutation or speed claim made. | ## Inputs Required: one or more suspected hot paths named by the user (file, function, or call site) and the workload or input shape that makes each path hot. Optional: prior measurements, profiling traces, or environment constraints the user supplies. Absent measurements are treated as unmeasured, not as evidence of slowness. ## Procedure 1. For each named hot path, read the source and surrounding call graph read-only; record the inputs, allocations, loops, and branches that plausibly dominate cost. Done when: every named path is read and its cost-plausible elements recorded. …

How to install
mdr add outlinedriven/odin-claude-plugin/fastopt@sha256:7730e0c6a740a506The line at the top of this page pins the label git:20260905.4d9e207, 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.
