Turn a design, idea, sketch, brief, or product concept into the simplest feasible project plan spanning design, deployment, security, operations, finance, tool reuse, and verification.
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
# project-engineer ## Purpose During Development Use this skill when Codex and similar AI coding agents need to turn a design, idea, sketch, brief, or product concept into a feasible project plan and implementation path. This is a reusable development-time reasoning framework. It is not runtime code and must not be coupled into the product being built. ## When To Apply - new project planning from an idea, design, prototype, screenshot, or vague brief - early implementation planning before repository structure, tooling, deployment, or cost model is clear - requests that need coordination across design, application engineering, deployment, security, operations, and finance engineering - project rescue work where the simplest feasible path needs to be recovered from an overbuilt plan ## What To Inspect - the repository `AGENTS.md`, `PLAYBOOK.md`, and `skills/PLAYBOOK.md` - existing source layout, package managers, CI, deployment files, infrastructure files, and environment examples - product brief, design inputs, screenshots, diagrams, tickets, or user-provided constraints - existing tools and services already present in the repo or organization …

How to install
mdr add polakinio/ai-engineering-playbook/project-engineer@sha256:deacca9c1787192eThe line at the top of this page pins the label git:20260812.5b0dd88, 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.
