oneport-docgen

Enterprise documentation for any codebase — generated locally, never uploaded.

Point it at a repo and it produces a formal, sign-off-ready Technical Design Document as a branded PDF, an editable Word (.docx) file, and Markdown — with the full apparatus enterprises expect: cover page, document-control table, revision history, classification banner, numbered sections and an approval/sign-off page.

It reuses oneport-context's local repo index (file → module → repo understanding), so your code never leaves the machine. Runs on your own model key (Google Gemini free tier) or fully heuristic — free and offline.

Quickstart

pip install oneport-docgen
oneport-docgen generate ./my-repo

You'll be asked for the title, version, classification and sign-off names (authors are pre-filled from git). Out come three files in ./my-repo/.docgen/:

my-repo-technical-design-document.pdf     # branded, ready to hand to an exec/auditor
my-repo-technical-design-document.docx    # editable in Word / SharePoint
my-repo-technical-design-document.md      # for the wiki / repo

Set a key for richer prose (optional):

export GEMINI_API_KEY=…       # free key at aistudio.google.com/apikey

Without a key it still generates a complete, accurate document — module breakdown, tech stack and file inventory come straight from the code; only the narrative sections get shorter.

Commands

Document types (--type)

oneport-docgen generate ./repo --type sbom      # audit-grade dependency/license report

The SBOM is generated deterministically from your manifests (requirements.txt, pyproject.toml, package.json, go.mod, Cargo.toml, Gemfile, composer.json, pom.xml, Gradle) — no AI, fully auditable. For Python it resolves real versions and licenses from installed metadata, and flags unpinned versions, unknown licenses and copyleft components.

Useful flags

oneport-docgen generate ./repo \
  --format pdf,docx \                 # pick outputs (pdf, docx, md)
  --scope module:services/billing \   # document just one module
  --classification Internal \
  --version 2.1 --status "In Review" \
  --author "Ada Lovelace" --approver "Grace Hopper" \
  -y                                   # non-interactive (for CI)

Branding

oneport-docgen init            # writes docgen.toml

[brand]
company = "Acme Corporation"
logo    = "assets/logo.png"
primary = "#0F172A"
accent  = "#4F46E5"
footer  = "Confidential — internal distribution only"

Every generated document then carries your company name, logo and colours.

Where it's going

• Phase 1 — formal deliverable (shipped): branded PDF + editable DOCX + Markdown.
• Phase 2 — compliance doctypes (in progress): --type sbom shipped; threat model and ADR log next.
• Phase 3 — living docs: oneport-docgen check fails CI when the code and the document drift apart (every claim is provenance-linked to the source).
