Build Phase Documentation

← Back to Documentation Play

What Happens in This Phase

The Build phase compiles code, resolves dependencies, and produces deployable artifacts. Documentation here is highly structured—build configurations, container specs, and Software Bills of Materials (SBOMs). AI excels at generating these artifacts directly from code and configuration files with minimal human intervention.

Where AI Helps

  • Generating SBOMs from dependency manifests and container images
  • Documenting build configurations from CI/CD pipeline definitions
  • Creating container specifications from Dockerfiles and compose files
  • Maintaining dependency documentation with version and license information
  • Identifying undocumented build steps through pipeline analysis

Example: Software Bill of Materials (SBOM)

This example demonstrates GenAI Completion—AI generates comprehensive dependency documentation directly from structured inputs with minimal human intervention beyond validation.

Context Setup

Before prompting, the pipeline provided:

  • requirements.txt and Pipfile.lock with pinned versions
  • Dockerfile specifying base image
  • Access to CVE database for vulnerability lookup
  • CycloneDX output format specification

Prompt

"Generate SBOM documentation for this Python application based on the requirements.txt, Pipfile.lock, and Dockerfile. Include package name, version, license, and known vulnerabilities from the latest CVE database. Format as CycloneDX JSON."

Output

{
  "bomFormat": "CycloneDX",
  "specVersion": "1.4",
  "components": [
    {
      "name": "requests",
      "version": "2.28.1",
      "type": "library",
      "licenses": [{"license": {"id": "Apache-2.0"}}],
      "purl": "pkg:pypi/requests@2.28.1"
    },
    {
      "name": "cryptography",
      "version": "38.0.4",
      "type": "library",
      "licenses": [{"license": {"id": "Apache-2.0"}}],
      "purl": "pkg:pypi/cryptography@38.0.4",
      "vulnerabilities": []
    }
  ]
}

What AI-Generated Build Documentation Often Misses

  • Transitive dependencies - Deep dependency trees may be incomplete
  • Build environment specifics - OS versions, compiler flags, environment variables
  • License compliance nuances - Conflicting licenses in dependency chains
  • Internal package sources - Private registries or vendored dependencies
  • Build reproducibility requirements - Pinned versions vs. ranges

Human reviewers must validate SBOM completeness against actual build artifacts.

Governance Checklist

Before accepting AI-assisted Build phase documentation:

  • [ ] SBOM includes all direct and transitive dependencies
  • [ ] License information accurate and compliance-checked
  • [ ] Container base images documented with versions
  • [ ] Build configuration matches actual CI/CD pipeline
  • [ ] Vulnerability scan results current

Brownfield Additions

For modernization efforts, Build phase requires additional focus:

  • Legacy build process documentation - AI analyzes makefiles, scripts, and job control; humans validate completeness
  • Compatibility constraints - Document dependencies on legacy libraries or runtime versions
  • Dual-build documentation - Maintain docs for both legacy and modernized build paths during transition
