Document Systems

Experimental — not submitted to the OpenAI Plugins Directory. Document Systems is a public research prototype with verified engineering properties and unproven product utility. Do not treat its validation receipts or release gates as evidence that a document is correct, fit for use, or safer than an ordinary review.

Document Systems is a proposal-scoped Codex plugin prototype for composing, validating, gating, packaging, auditing, and rendering consequential documents from a small semantic model. It is published as a Banks Inc. service publication at documents.banksinc.us.

It packages four skills and a stateless MCP server. The server writes nothing, accepts nothing, and cannot make a document authoritative or operative.

Capabilities

• Compose immutable, content-addressed document Expressions.

• Validate structure, profile conformance, evidence references, status separation, caller-reviewed semantic invariants, and supplied lineage.

• Compile one-call release summaries or portable content-addressed packets.

• Verify a portable packet after caller-managed storage or transfer.

• Render traceable human-review, human-action, or machine projections.

• Audit authority, exceptions, evidence, readiness, and acceptance boundaries.

The v0.1 profile catalog contains:

• normative

• operational

• research

• human-agent

Each Expression selects exactly one primary profile and at most one secondary profile.

Install

Add this GitHub marketplace:

codex plugin marketplace add bankszach/document-systems

Install the plugin:

codex plugin add document-systems@document-systems-public

Start a new Codex session, then invoke a skill explicitly:

$compose-document-system Turn this operating requirement into a proposal Expression.

The plugin requires Node.js and uses no third-party runtime packages.

Tools

All tools advertise readOnlyHint: true, openWorldHint: false, and destructiveHint: false, and each declares an output schema.

The public stateless Streamable HTTP endpoint is:

https://documents.banksinc.us/mcp

Safety boundary

An Expression is always PROPOSED. Validation can establish structural properties and conformance to caller-reviewed semantic assertions, but it does not independently establish:

• source truth or source authority;

• behavioral success or intended-use fitness;

• human acceptance or operative status;

• repository head or complete lineage;

• persistence of returned objects.

Every returned object declares persistence_status: NOT_PERSISTED. A FULL release packet is portable and content-addressed so a caller can store and later verify it; the service itself does not store or resolve packets.

Validate

npm test

The test suite exercises deterministic composition, content tampering, profile drift, supplied lineage, evidence laundering, lifecycle contamination, profile overcomposition, fail-closed action rendering, HTML escaping, element-level traceability, semantic drift, typed allocation completeness, portable-packet verification, and the no-write boundary.

Run the external OSHA, CISA, CDC, and NIST benchmark:

npm run benchmark:real-world

See Real-World Benchmark v0.2 for the measured self-authored structural and semantic-defect detection, payload reduction, and why those results do not establish marginal product value.

See Experimental Evaluation v0.3 for the World Control Plane failure that caused the production claim to be withdrawn and the evidence required before reconsidering public submission.

Distribution status

This repository is a public GitHub marketplace for Codex and contains a public experimental HTTPS MCP transport, policy pages, test cases, and dormant submission materials. The plugin has not been submitted to OpenAI for review. Banks Inc. will not submit or publish it in the universal Plugins Directory unless a blinded baseline-versus-candidate evaluation demonstrates repeatable marginal value.
