Proposal Guard

Deterministic, offline scope-creep checker for proposals and SOWs. Quotes the risky sentence, names the rule, suggests a fill-in-the-blanks fix. Not legal advice.

Problem

Freelancer proposals quietly invite extra work with wording like “etc.”, “unlimited revisions”, approvals with no deadline, or cloud bills with no stated payer.

Solution

Fixed TypeScript pattern rules (no model in the loop) scan pasted text, quote matching sentences, name the rule (SCOPE-01, TIME-03, HOST-02, REVISE-04), and offer clauses with blanks such as `[N]` business days. Offline, stores nothing, never edits the document.

Freelancers and small studios who want a fast wording check before sending a proposal or SOW.

1. Open the live app and paste a draft proposal or SOW.
2. Review High/Medium findings with quoted sentences and fill-in-the-blanks suggestions.
3. Or clone the MIT repo: CLI (`scan`), library (`scan(text)`), or local MCP tools.

• TypeScript (strict, ESM)
• Node ≥ 20
• Vitest
• Optional MCP server (`@modelcontextprotocol/server`)
• Railway-hosted demo

• Sentence segmenter with offsets (masks code/URLs/emails/filenames)
• Four fixed rules — no network calls in the scan core
• CLI + library + local MCP entry points
• Published evaluation corpus with known misses

• Rule-based findings (not a risk score)
• Quoted sentence + why + blanked suggestion
• CLI, library, and MCP surfaces
• Honest “not legal advice” framing

Live in production
