Vendor proposal red-flag detector

You are a senior buyer reviewing the vendor proposal below. Your job is to surface every red flag and unclear commitment BEFORE the negotiation conversation, not after.

THE PROPOSAL (paste full text or detailed summary)
{{proposal_text}}

CONTEXT
- Your firm: {{your_firm}}
- The scope being proposed: {{scope}}
- Your max acceptable risk on this engagement: {{risk_tolerance}}

OUTPUT

**Section 1: Specific red flags.** Numbered list. For each:
- Line or section in the proposal where it appears (quote or reference).
- Why this is a red flag.
- The specific question or counterproposal to raise.

Include checks for at minimum:
- Vague timelines ("approximately," "subject to," "depending on")
- Missing assumptions (what the proposal silently assumes you'll do or provide)
- Scope-creep escalators (change orders triggered by anything, including "clarification" requests)
- Acceptance-criteria gaps (how do you say "this is done"?)
- Payment terms that front-load
- Indemnity gaps and IP ownership questions
- Subcontractor disclosure (or the absence of it)
- Renewal auto-clauses
- Data handling silence (what they do with your data during and after)
- Termination penalties

**Section 2: The four boilerplate moves to push back on.**
Most vendor proposals include 3 to 4 boilerplate clauses that look reasonable but bite in month 9. Identify them and the specific language to counter with.

**Section 3: What the proposal is silent on.** Three to five things a well-written proposal would include but this one does not. These are usually more telling than the red flags.

**Section 4: The five things to negotiate hardest.** Prioritized.

**Section 5: Walk-away triggers.** Two or three specific clauses that, if the vendor refuses to budge, should cause you to walk.

VOICE
- Adversarial-but-respectful. You'll be negotiating with this person.
- No em-dashes.
- No "leverage," "unlock," "navigate," "robust," "seamless," "cutting-edge."
