Check a document against ScopeSpec 0.1

Run the check

Paste a ScopeSpec project brief or quote. The rules below are the ones it applies — the same file you can download and run yourself.

No JavaScript? Every rule is in the tables below and in the downloads — the check is the only part of this page that needs it.

What it checks, and what it does not

Three rule kinds, because these are the three the published schema states unambiguously enough to extract without interpretation:

• required field present
• JSON type
• allowed values (enum)

It does not check the following draft-07 keywords, which the schema uses and this checker does not implement: format, minLength, minimum, pattern. A document this page calls conforming may still fail one of them in a full schema validator.

And it does not check whether the document is right. Structural conformance says a brief is shaped the way the standard specifies. It says nothing about whether the measurements are accurate, the assumptions reasonable, or the project described the one you mean. No score is produced, no contractor is judged, and no price is predicted or validated.

Download the rule set

The rules are extracted from the published JSON Schema by a build step, so they cannot describe a version of the standard that does not exist. Take them and implement the check yourself — that is the point of publishing a standard.

• Conformance rules (JSON) — every rule, plus the declared limits of the check.
• Conformance rules (CSV) — the same table for a spreadsheet.
• The JSON Schema itself — the source these are derived from, and the authority if they ever disagree.

Project brief — 71 rules (58 required)

The document a homeowner sends to every bidder. A field left out here is a question every bidder answers privately and differently, which is exactly how two quotes for “the same job” stop being comparable.

Quote — 15 rules (13 required)

The document one bidder sends back. These are the fields the quote comparison worksheet sets side by side, and a blank in any of them is where two apparently identical prices stop being identical.

Corrections

If the checker accepts a document the standard rejects, or rejects one it accepts, that is a defect and we want to hear about it: Ben Davis, ben.davis@bidbro.com. The schema is the authority; a disagreement between it and this page is this page’s bug.
