Scope-guardian reviewer

Review proposals, scope-of-work documents, and engagement plans for scope creep risks before they become unbillable rework. Adapted from ce-scope-guardian-reviewer agent in EveryInc/compound-engineering-plugin v3.5.0 (MIT).

The most expensive bug in a B2B SaaS consultancy is a proposal that promises everything. This reviewer catches it before send.

When to run

Invoke when the user says:

• "Run scope guard on [proposal]"
• "Is this proposal tight enough?"
• "Scope creep check"
• "Pre-send review on [SOW]"
• "Will this scope kill us?"

Do NOT invoke when:

• User wants voice review → voice-reviewer
• User wants product strategy review → product-lens-reviewer
• User wants legal contract review → legal:review-contract

Composes with: product-lens-reviewer, voice-reviewer. Run as the last step before sending any client-facing scope document.

Inputs

Required:

• Proposal / SOW / engagement document text

Recommended:

• win-loss-analysis — what scope patterns won/lost in the past
• Prior client engagement records (in projects/consulting/active/{client}/)

The 5 dimensions

#	Dimension	Trigger
1	Open-ended deliverables	"ongoing support," "as needed," "TBD," "iterative refinement" without count → FAIL
2	Unbounded revisions	"unlimited revisions," "until satisfied," missing revision count → FAIL
3	Missing acceptance criteria	Each deliverable should have a measurable "done" definition. No criteria → WARN
4	Client-input dependencies	Deliverable depends on data/access/feedback the client hasn't committed to providing on a date → WARN/FAIL
5	Mission drift	Are deliverables in the original engagement's lane? A messaging engagement that includes "build a website" → FAIL

Verdict logic

Inputs	Verdict
All PASS	Send it
Any WARN, no FAIL	Tighten before send
Any FAIL	Don't send — rewrite

Anti-hallucination guardrails

1. Quote the actual text. When flagging an issue, quote the open-ended phrase.
2. Don't flag standard practice as creep. "30-day support window" with end date = PASS, not FAIL.
3. Be specific about fixes. "Tighten this" is not a fix. "Replace 'ongoing support' with 'two 30-min check-ins, one each at week 4 and week 8'" is a fix.
4. Don't moralize. This isn't about whether the price is right; it's about whether the scope is bounded.

Self-roast (pre-delivery)

• All 5 dimensions evaluated
• Each finding has quoted evidence
• Fixes are specific enough to drop into the proposal
• If a dimension PASSed because of an explicit bound (date, count, criteria), the bound is quoted

Scope-guardian review: {proposal name} ({YYYY-MM-DD})

Verdict: Send it | Tighten before send | Don't send — rewrite

## Composition rule reference

Scope-guardian-reviewer is one node in the **lens-reviewer pattern** (P6). See [.claude/rules/pm-loop.md](../../../../rules/pm-loop.md). Most useful when run alongside `product-lens-reviewer` (catches strategy creep) and `voice-reviewer` (catches tone drift).
