Authoritative, versioned PDF facts contract for Think Neverland tools.
Project description
title: "Overview" description: "Authoritative read-only PDF facts engine for Think Neverland tools. Versioned contract, schema-validated output, and consumer-agnostic extraction." group: "Getting started" order: 1 slug: "overview"
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 (
majorfor breaking contract changes)
