Knowledge base from the GAO Cost Estimating and Assessment Guide (GAO-20-195G). Use for program cost estimating: the four characteristics of a reliable estimate (comprehensive, well documented, accurate, credible) and the 18 best practices; the 12-step cost estimating process (purpose, plan, technical baseline, WBS, ground rules and assumptions, data, point estimate, sensitivity, risk/uncertainty, document, present, update); estimating methods (analogy, parametric, engineering build-up…
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
<!-- argument-hint: [characteristic, 12-step process step, estimating method, risk/uncertainty, EVM term, audit, software/learning-curve/AOA, chapter number] --> # GAO Cost Estimating and Assessment Guide (GAO-20-195G) **Source**: GAO (US Government work, public domain) | **Chapters**: 8 ## When to use Use this skill to develop, manage, or evaluate a program **cost estimate**: framing the estimate's purpose and scope, structuring it with a WBS, choosing estimating methods, turning a point estimate into a risk-adjusted budget, documenting and updating it, auditing it against GAO's reliability criteria, and connecting it to **earned value management** for execution. This is the cost-estimating companion to the GAO `gao-schedule` and `gao-tra` guides and the management-side counterpart to a program's life cycle cost estimate. **Prerequisites:** none — plain Markdown; no MCP server, API key, or licence tier needed at runtime. ## How to Use This Skill - **Without arguments** — load the core frameworks below: the four characteristics + 18 best practices, the 12-step process, the estimating methods, risk/uncertainty, EVM, and the specialized techniques. …

How to install
mdr add jgsystemsconsulting/jgs-se-knowledge-packs/gao-cost@sha256:a446bb46063c8d68The line at the top of this page pins the label git:20260624.177d6b6, 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.
