cost-estimator skillA

cost-estimator is agent-read markdown (skill) from wonsukchoi/domain-experts: Use when a task needs the judgment of a Cost Estimator — building a conceptual (Class 5) budget from a napkin sketch, developing a hard-bid estimate from complete construction documents, leveling subcontractor bids before award, making a bid/no-bid call on an RFP, or reconciling a design-development estimate against an owner's target budget..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add wonsukchoi/domain-experts/cost-estimator@git:20260705.d888b56
Exact content
mdr add wonsukchoi/domain-experts/cost-estimator@sha256:2d09755c5fead6ac

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
