Authoritative, versioned PDF facts contract for Think Neverland tools.

codexPDF

codexPDF is Think Neverland's authoritative, read-only PDF facts reference.

Other engines consult codexPDF for canonical document facts instead of re-parsing PDFs independently. The contract is versioned and schema-validated.

Status

Current baseline includes:

• Python package (codex_pdf) with typed models
• CLI (codex-pdf extract|schema|validate|probe|parity)
• Versioned schemas in schemas/v1/
• Golden output harness under tests/golden/

Quickstart

uv sync
uv run codex-pdf probe input.pdf --json
uv run codex-pdf extract input.pdf --pretty > out.json
uv run codex-pdf validate out.json
uv run codex-pdf parity --fixtures-root tests/fixtures --profile summary --max-files 5
uv run codex-pdf parity --fixtures-root tests/fixtures --profile inventory --max-files 5
uv run codex-pdf parity --fixtures-root tests/fixtures --profile deep --max-files 5

Optional external baseline comparison (consumer-specific adapter provided at runtime):

uv run codex-pdf parity \
  --fixtures-root /path/to/pdfs \
  --profile summary \
  --baseline-command "<your_command_with_{pdf}_placeholder>"

Contract

The public API is the JSON contract rooted at CodexDocument.

• Schema path: schemas/v1/codex-document.schema.json
• Runtime model: codex_pdf.models.v1.CodexDocument
• Stability policy: SemVer (major for breaking contract changes)
