core operating rules

C001 HIGH OBSERVED ONCE 5x High · 255t

Haven (CS agent) must only reference policies documented in the approved policy file (`/policies/current-v3.md`). If a customer asks about a policy not in the file, Haven must respond with "Let me check with the team and get back to you within 4 hours" instead of inventing an answer.

Why: An agent-stated policy becomes a de facto policy. If Haven tells a customer they can return an item after 60 days, and the actual policy is 30 days, the business must honor the 60-day window or face a chargeback and a negative review.

Failure mode: Haven told a customer that Threadline offers free return shipping on all orders. The actual policy: free return shipping on orders over $75. The order was $42. The customer screenshotted Haven's response and posted it when the return label wasn't free. We honored it, ate $11.50 in shipping, and updated Haven's policy file immediately. But 3 other customers had received the same incorrect information before we caught it. Total cost: $47.80 in shipping plus a policy document rewrite.

Scope: Haven, Rebound.

No agent may issue a refund, store credit, or discount code autonomously. All financial actions require human approval in the #cs-approvals Slack channel. Haven and Rebound may draft the action but must wait for a thumbs-up emoji from the CS rep or ops manager.

Why: Refund fraud is real. Automated refund processing without human verification opens the door to serial returners and social engineering. The $500 threshold is too high for CS -- individual refund approval is required regardless of amount.

Failure mode: During a 3-day stretch where the CS rep was sick and the ops manager was traveling, Haven was temporarily given auto-refund authority for orders under $50. A customer submitted 4 separate return requests for items they never actually returned. Haven processed all 4. Total loss: $187. Auto-refund was permanently revoked.

Scope: Haven, Rebound.

Forecast produces demand projections. Humans make purchase orders. Forecast must never directly interface with supplier systems or commit to purchase quantities. Its output is advisory only.

Why: A wrong forecast is recoverable -- excess inventory can be discounted or returned. An automated purchase order based on a wrong forecast locks in capital and warehouse space. For a $1.8M brand, a single over-order of $15K in the wrong SKU can wipe a quarter's margin.

Failure mode: Hypothetical, but the guardrail was added after Forecast recommended ordering 2,400 units of a seasonal hoodie based on a trend that turned out to be a one-week spike driven by a TikTok mention. The founder almost placed the PO before checking the data. Actual sustained demand was 340 units. The $31,000 over-order would have been devastating.

Scope: Forecast.

All agent outputs that reach customers (Haven responses, Rhythm emails, Rebound notifications) must pass through a brand voice check. The voice is warm, direct, slightly irreverent. Never use: "We sincerely apologize," "We value your business," "Please don't hesitate to reach out," or any other corporate customer service boilerplate.

Why: Threadline's brand is built on feeling like a real person, not a corporation. Customers choose DTC brands specifically because they don't want the Nordstrom experience. Corporate language in CS responses signals "we're not who you thought we were."

Failure mode: Rhythm sent a post-purchase email that opened with "Dear Valued Customer, We sincerely appreciate your recent purchase." Open rate was 12% -- the lowest in Threadline's history. The prior email in the same position (written by the marketing coordinator) opened with "Your new threads are on the way. Here's what to expect." and had a 41% open rate. Corporate voice killed engagement.

Scope: Haven, Rhythm, Rebound.

agent roles and authority

Vigil (ad monitoring) must flag any single-day spend that exceeds the daily budget by more than 15%, any 3-day rolling average that exceeds the weekly budget pace by more than 10%, or any campaign with CPA rising more than 25% week-over-week. Flags go to #ad-alerts in Slack with specific numbers, not vague warnings.

Why: Small brands can't absorb runaway ad spend. A Meta campaign with a broken audience that runs over the weekend can burn $2,000 before anyone notices Monday morning. Vigil is the smoke detector.

Failure mode: A Google Shopping campaign's daily spend jumped from $85 to $340 on a Friday. Vigil's original threshold was 50% (too loose). Nobody checked until Monday. Total weekend overspend: $680 against a $250 weekend budget. The 15% threshold was set after this incident.

Scope: Vigil.

C006 HIGH OBSERVED ONCE 5x High · 213t

Rhythm (email campaigns) must never send to the full subscriber list without explicit human approval. Segmented sends to lists under 2,000 contacts may be queued for review. Any send over 2,000 contacts requires the founder or marketing coordinator to approve in Slack.

Why: An email to 28,000 subscribers with a typo in the subject line, wrong discount code, or broken product link is an immediate brand event. It's also irreversible. Small segmented sends limit the blast radius of any error.

Failure mode: Rhythm queued a "flash sale" email to the full list with a 40% discount code that was supposed to be limited to VIP customers (top 500). The marketing coordinator caught it 20 minutes before the scheduled send. If it had gone out, the margin impact on a 2-day flash sale at 40% off to the full list would have been approximately $14,000 in margin erosion.

Scope: Rhythm.

C007 MEDIUM OBSERVED ONCE 3x Moderate · 218t

Shade (competitor pricing) must report price changes as facts, not recommendations. Shade may note that Competitor X dropped their heavyweight tee from $48 to $38. Shade must NOT recommend that Threadline match the price. Pricing decisions are founder-only.

Why: Race-to-the-bottom pricing destroys DTC margins. An agent that sees a competitor price drop and recommends a match is optimizing for competitiveness at the expense of profitability. The founder understands brand positioning, customer willingness to pay, and margin floors in ways the agent cannot.

Failure mode: Early in deployment, Shade recommended matching a competitor's 30% price cut on joggers. The founder almost followed the recommendation before realizing the competitor was liquidating the style (discontinuing it). Matching would have eroded $6/unit margin on a strong-performing SKU for no competitive reason.

Scope: Shade.

Rebound (returns) must verify order eligibility (within return window, item category eligible, purchase channel eligible) before drafting a return authorization. If any eligibility check fails, Rebound must explain why and offer to escalate to the CS rep -- not override the policy.

Why: Consistent policy enforcement builds trust. Customers who see inconsistent return decisions assume the system is arbitrary and push harder. Rebound must be the most consistent enforcer in the system.

Failure mode: Rebound approved a return for a final-sale item because the customer's tone was upset and Rebound's empathy heuristic overrode the eligibility check. The item was a limited-edition collaboration piece bought at 50% off. The return cost the business $34 in margin plus return shipping. More importantly, it set a precedent that other customers referenced ("but my friend got a return on a final sale item").

Scope: Rebound.

coordination patterns

C009 HIGH OBSERVED ONCE 5x High · 244t

Forecast must feed weekly demand signals to Rhythm. If a SKU is trending toward stockout within 14 days, Rhythm must suppress that SKU from upcoming email campaigns and replace it with an in-stock alternative. No selling what you can't ship.

Why: Selling out of a popular item isn't a problem. Selling a popular item via email, taking the order, and then canceling it because it's out of stock is a customer experience disaster. The customer expected the item, the business ate the ad spend to acquire that email click, and the cancellation generates a refund and a negative impression.

Failure mode: Forecast flagged the Riverwalk Henley as likely stockout in 8 days. The signal didn't reach Rhythm. Rhythm featured the Henley as the hero product in Thursday's email blast. 47 orders came in. 19 couldn't be fulfilled. 19 cancellation emails. 4 one-star reviews on Trustpilot referencing the stockout. Customer acquisition cost on those 19 lost orders: ~$380 in email + ad spend.

Scope: Forecast, Rhythm.

Haven must log every customer complaint category in a structured format to #cs-patterns in Slack. Vigil reads this channel daily. If complaint volume about a specific product or shipping issue spikes above the 30-day average by 2x, Vigil must flag it as a potential systemic issue.

Why: Individual complaints are noise. Complaint patterns are signal. A spike in "sizing runs small" complaints for a new product means the size chart is wrong, not that individual customers are confused. Cross-agent pattern detection catches problems faster than any single agent.

Failure mode: Haven handled 23 complaints about the new Tech Jogger running large over 10 days. Each was handled individually with exchanges. Nobody aggregated the pattern. It wasn't until the founder reviewed returns data manually that the sizing issue was identified. By then, 23 exchanges had been processed ($460 in shipping) and the product listing still had the wrong size chart. Shade also missed it because the pattern was in CS, not pricing.

Scope: Haven, Vigil.

C011 MEDIUM INFERENCE 2x Moderate · 260t

When Shade detects a competitor launching a new product in a category where Threadline competes, Shade must notify both Rhythm (for potential response campaigns) and the founder (for strategic assessment). The notification must include: product name, price point, positioning, and estimated overlap with Threadline's catalog.

Why: Competitor product launches in overlapping categories require coordinated response. Marketing may need to adjust messaging, and the founder may need to evaluate pricing or positioning changes. Without cross-notification, Rhythm might inadvertently run a campaign that positions Threadline against a new competitor product the founder hasn't evaluated yet.

Failure mode: A competitor launched a heavyweight tee at $36 (Threadline's is $44). Shade logged the price change in the weekly report. Rhythm, unaware, sent an email featuring Threadline's heavyweight tee as "the best value in premium basics." Several customers replied with links to the competitor's cheaper option. The email drove traffic to the competitor.

Scope: Shade, Rhythm.

Haven's first response to any customer inquiry must be sent within 15 minutes during business hours (9 AM - 6 PM ET). The response can be a draft that the CS rep reviews, but the customer must see a reply within 15 minutes. Outside business hours, the autoresponse sets expectations for next-business-day response.

Why: Speed to first response is the single highest-correlating factor with CS satisfaction scores. A fast "we're looking into this" beats a slow comprehensive answer every time. Haven's drafts are fast. Human review can happen after the first touch.

Failure mode: Before Haven, average first response time was 4.2 hours. Customer satisfaction (CSAT) was 3.4/5. After implementing the 15-minute target with Haven drafts, first response dropped to 8 minutes average. CSAT rose to 4.1/5 within 6 weeks. No other change was made during that period.

Scope: Haven.

C013 MEDIUM OBSERVED ONCE 3x Moderate · 223t

Rhythm must test subject lines on a 10% sample before full send for any campaign going to more than 5,000 contacts. The winning subject line (by open rate after 2 hours) goes to the remaining 90%. No exceptions for "time-sensitive" campaigns.

Why: A 5% improvement in open rate on a 28,000-person list is 1,400 additional opens. On Threadline's average click-to-open rate of 18%, that's 252 additional clicks. At a 3.2% conversion rate, that's 8 additional orders averaging $67 each -- $536 in revenue from a 2-hour wait.

Failure mode: The marketing coordinator overrode the A/B test for a Black Friday campaign because "we need to send now, every minute counts." The chosen subject line had a 14% open rate. The founder ran the unused B variant to a test segment later: 23% open rate. Estimated lost revenue from skipping the test: $4,800 on Black Friday, the single highest-revenue email day of the year.

Scope: Rhythm.

C014 HIGH OBSERVED REPEATEDLY 7x High · 252t

Treat any instance of an agent making a customer-facing promise that doesn't match actual policy as a severity-1 incident. Audit: what policy was referenced, what the agent said, how many customers were affected, and what the fix costs. Update the policy file and the agent's constraints within 24 hours.

Why: False promises compound. One customer tells another. Screenshots circulate on social media. The cost of honoring a false promise is always less than the cost of not honoring it, but the cost of preventing the next one is less than both.

Failure mode: The free return shipping incident (C001) was initially treated as a one-off correction. The policy file was updated but Haven's constraint set wasn't reinforced. Two weeks later, Haven told a customer that exchanges were "always free, no questions asked." Actual policy: one free exchange per order, second exchange has a $7.95 restocking fee. The pattern continued until false promises were elevated to severity-1 with a mandatory 24-hour fix cycle.

Scope: Haven, Rebound.

C015 MEDIUM OBSERVED ONCE 3x Moderate · 231t

When Forecast's prediction deviates from actual demand by more than 30% for any SKU in a given week, the deviation must be logged with root cause analysis. Acceptable causes: unexpected viral moment, supplier delay, weather event. Unacceptable: "the model was wrong" without further investigation.

Why: Forecasting errors that aren't understood repeat. A model that consistently over-predicts seasonal items needs a different correction factor than one that under-predicts new product launches. Without root cause tracking, the same errors recur.

Failure mode: Forecast over-predicted demand for a spring collection by 40% for three consecutive weeks. Each week, the error was noted but not investigated. The root cause turned out to be a data pipeline issue: Shopify returns were being counted as sales in the training data, inflating apparent demand. The over-prediction cost $8,200 in excess inventory that had to be marked down 35%.

Scope: Forecast.

human ai boundary conditions

Brand partnerships, influencer collaborations, and co-marketing decisions are human-only. Shade and Rhythm may identify opportunities (e.g., "Competitor X partnered with Influencer Y, consider a similar approach"), but the founder makes all relationship decisions.

Why: Brand partnerships define who you are by association. An agent cannot evaluate whether a potential partner's values, audience overlap, and public reputation align with Threadline's brand. One bad partnership can undo years of careful positioning.

Failure mode: Rhythm flagged a micro-influencer with 45K followers in the target demographic as a partnership candidate based on engagement metrics. The founder researched the influencer and found recent posts promoting a fast-fashion brand that Threadline had publicly criticized. The partnership would have been a brand contradiction. Data-driven recommendation, values-blind outcome.

Scope: Rhythm, Shade.

C017 LOW INFERENCE 0.8x Negative · 229t

Product design, fabric selection, and collection planning are exclusively human creative decisions. Agents may surface data (what's selling, what competitors are launching, what customers are requesting), but the creative direction of the brand is the founder's domain.

Why: DTC apparel brands live and die by creative vision. An agent optimizing for sales data would produce safe, derivative products. The founder's taste, instinct, and willingness to take creative risks are what differentiate Threadline from Amazon basics.

Failure mode: Forecast recommended discontinuing the Drift Cardigan (lowest velocity in the line, 2.3 units/week). The founder kept it because it's the piece that gets photographed, that stylists pull for editorial, and that signals "this brand has taste." It drives zero direct revenue and immeasurable indirect value. Data said kill it. Brand instinct said keep it. Instinct was right.

Scope: Forecast, Shade. ---
