Automate the repetitive and keep builds reproducible

GDC-L1-CONTENT-0005

Strong4/5

Statement

Automate repetitive pipeline work (asset processing, builds, validation, deployment) and keep builds reproducible — same inputs, same output, from clean source control. Manual, non-reproducible builds waste time, hide "works on my machine" bugs, and make releases risky.

Rationale

Anything done by hand repeatedly is slow, error-prone, and a person's time wasted; automation converts that recurring cost into a one-time setup that runs reliably forever [S-gregory-game-engine-arch]. Reproducibility is the deeper requirement: if a build depends on undocumented local state, one machine's quirks, or manual steps, then bugs can't be reliably reproduced (QA-0003/0004), releases are gambles, and teammates get different results from the same source. Automated, reproducible builds from version control give a single source of truth, catch integration breakage early (continuous builds), and make shipping a routine rather than a ritual. This is the build/deployment side of investing in tooling (CONTENT-0001) and of the iteration-speed and quality-in commitments (ARCH-0005, QA-0005).

Applies when

Any project past prototype scale, and essential for any team (where "works on my machine" bugs and integration breakage multiply). The larger the team and the more frequent the builds, the more it matters.

Does not apply / Exceptions

A solo weekend prototype can build manually. Full CI/CD and elaborate automation have setup and maintenance cost that tiny projects may not recoup. The principle is "automate what's repetitive and keep builds reproducible," scaled to the project — not "build a AAA build farm for a game jam."

Implementation

Put everything needed to build in version control; script the build so it's reproducible from a clean checkout. Automate asset processing, validation (CONTENT-0004), and (as the team grows) continuous integration. Use non-destructive workflows and source control for assets, not just code. Make releases a repeatable, tested process (feeding QA-0004 and SHIP). Measure and shorten build times (part of iteration speed, ARCH-0005).

Disagreement

Automation/CI investment (reliability, speed, reproducibility — but setup and maintenance cost) vs. lean manual builds (start sooner, less infrastructure — but brittle and unreproducible at scale). Scales with team size and build frequency; solo/tiny projects lean manual, teams automate.

Notes

The build/reproducibility principle of CONTENT; the deployment side of tooling investment (CONTENT-0001), enabling reliable bug repro (QA-0003/0004) and shipping (SHIP). Confidence 4.
