ppa-optimize from vibeic/vibe-ic is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Propose bounded, reversible actuator moves that trade power, performance and area against each other — placement density, clock period, synthesis effort, buffering, floorplan aspect — each with the effect it predicts, the remeasurement that would falsify it, and its rollback. Use when the user says "improve PPA", "close timing", "shrink area", "reduce power", "what should I try next", or when a closure loop needs its next candidate.
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
# PPA Optimize ## The boundary this skill lives inside This skill produces a **structured proposal**. It never produces a gate verdict, and it never reports that a move worked. A proposal becomes a result only when `ppa-measure` re-reads the artefacts afterwards and a deterministic program — `_ppa/feasibility.py` and `_ppa/pareto.py` per `docs/PPA_INTERFACES.md` §4 — compares the records. That ordering is the whole point. The failure mode it prevents is the one that looks most like success: a model proposes a change, the change is applied, and the same model reports the improvement it predicted. Nothing in that loop is a measurement, and the number it produces is indistinguishable from one that is. Every candidate this skill emits therefore carries four things that make it falsifiable: the actuator, the predicted effect, the remeasurement that would refute the prediction, and the rollback. ## When to use Trigger when the user: - Has measured PPA and wants the next thing to try - Is missing a target on one axis and wants to know what it costs on the others - Needs candidates for a closure controller (`_ppa/closure.py`) to actuate …

How to install
mdr add vibeic/vibe-ic/ppa-optimize@sha256:22463101f347dac3The line at the top of this page pins the label git:20261106.a0a79f8, 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.
