Purpose

Design the rules of engagement that govern discounting off list price — the artifact that Deal Desk and AEs operate under. Three deterministic tools:

1. discount_matrix_builder.py — builds a 4-dimensional matrix (ARR band × term length × payment terms × strategic value tier), each cell carrying an approved discount band backed by current win-rate + NRR data, plus an approver tier (AE / Manager / Director / VP / CFO).
2. exception_router.py — when an asks-for-discount lands outside the matrix, routes it through the named approver chain, attaches required compensating commitments (multi-year prepay + named expansion path + reference commitment + MSA tightening), produces machine-readable audit-trail metadata, and flags precedent risk if 3+ similar exceptions have landed in the trailing quarter.
3. policy_linter.py — lints the matrix for governance defects: approver inversion, band inversion, margin-floor violation, coverage gaps, cliff edges, undefined strategic tiers, inconsistent margin floors, thin data backing.

The output is the policy itself (matrix + exception flow + lint report), not a per-deal application of it.

When to use

• A new Head of Commercial or Head of Deal Desk is writing the company's first formal commercial policy
• The existing matrix is older than 6 months and discount drift is showing in margin reviews
• Reps are citing "Maria approved 28% on Acme last quarter" as precedent and you need to break the precedent loop
• Q-over-Q exception count is rising and you suspect the matrix bands are mispriced
• CFO has tightened the margin floor and the matrix needs to be rebuilt against the new constraint
• A board / exec is asking "why do we discount this much?" and you need a data-backed defensible policy

Do NOT use this skill to:

• Approve a specific deal — that's commercial/skills/deal-desk
• Set the pricing model + list price — that's commercial/skills/pricing-strategist
• Author a proposal / SOW / MSA prose — that's business-growth/contract-and-proposal-writer
• Make the strategic "when do we hire a VP Sales" call — that's c-level-advisor/cro-advisor

Workflow

1. Audit current discount distribution. Pull the last 4 quarters of closed-won + closed-lost deals from CRM. Fill assets/policy_design_template.md (~20 minutes). Capture: arr, discount_pct, term_months, payment_terms_days, strategic_value, win_lost, nrr_12mo per deal.

2. Design the data-backed matrix. Run scripts/discount_matrix_builder.py --input policy_intake.json --profile {saas|enterprise-software|api|marketplace|services}. Output is a 4-dimensional matrix with approved discount band + approver tier + margin floor + observed win-rate + observed NRR per cell. Cells with n < 5 observed deals are flagged THIN.

3. Design the exception flow. Run scripts/exception_router.py --sample to see the structure. For each severity band of exception (0-5 pts over, 5-10, 10-20, 20+), the router enforces required compensating commitments. Codify the flow in your policy doc; the router becomes the operational implementation.

4. Lint the matrix. Run scripts/policy_linter.py --input matrix.json. Get a ranked findings report — BLOCKER / MAJOR / MINOR — across 10 lint rules. Resolve every BLOCKER before publishing the matrix to AEs.

5. Publish + quarterly review. Publish the matrix as a versioned artifact. Re-run the builder and the linter every quarter against the new 4-quarter rolling deal corpus. Cells where observed NRR < target_nrr are flagged for review.

Scripts

All three: stdlib-only, --help, --sample, --input <json>, --output {markdown,json}.

Assumptions

• The skill assumes the pricing model and list price already exist (set via commercial/skills/pricing-strategist). Commercial-policy governs discounts off list — it does not set list.
• The CFO owns the min_margin_pct constraint (margin floor). The CRO / Head of Deal Desk owns the max_discount_pct_without_exception constraint (band cap). The skill keeps these inputs separate by design (per Bain Pricing Power — mixing accountability is the most common cause of policy drift).
• Industry profiles bake in customary band widths. Companies with idiosyncratic economics should pass overrides via the input JSON.
• The matrix is data-backed but not data-driven: the band is set by the constraints + profile; observed data is annotation that tells you whether the cell is performing. If observed NRR < target, that's a signal to review the band, not to keep discounting deeper.
• "Strategic value" tiers (logo, expansion, lighthouse) are useful only if defined with concrete tests. The lint rule L06 enforces this.
• This is a policy-design skill, not a deal-approval skill. It never says "approve" — it produces the matrix + exception flow that deal-desk then applies.

Anti-patterns

• Setting discount bands without data backing. "VP Sales argued for it in a Slack thread" is not data backing. If you can't show win-rate and NRR for the band, the band is rhetoric. (Caught by data_backing per cell + lint L08.)
• Letting precedent set policy. "Maria approved 28% on Acme last quarter" is not a band — it's an exception that didn't break the policy. exception_router.py flags 3+ similar exceptions as a signal that the matrix is wrong, not the deal. (Anti-pattern AP-1.)
• Approving exceptions without compensating commitments. Discount-for-nothing is a leak (Winning by Design). Every exception severity band requires non-negotiable commitments. (exception_router.COMPENSATING_LIBRARY.)
• Cliff edges at round-number ARR thresholds. A hard $100K threshold produces deal-size gaming within 2 quarters (MIT Sloan agency theory). Smooth the gradient. (Lint L05.)
• "Strategic value" as an undefined catch-all. If "strategic" is undefined, within a quarter 60% of deals will be flagged strategic and the matrix is dead. Define with concrete tests. (Lint L06.)
• No quarterly review. Markets shift; matrices unchanged for 12 months are mispriced. Re-run the builder and linter every quarter. (Anti-pattern AP-8.)
• Mixing CFO and CRO accountabilities. CFO owns the margin floor; CRO owns the band cap. Same accountable owner = predictable drift toward whatever they're compensated on (Bain Pricing Power).
• Skipping the lint pass before publishing. BLOCKER findings (approver inversion, margin-floor violati
