Your team has Claude Pro. One person gets value from it. Everyone else gave up.

# M&A Due Diligence Red Flag Scanner

CONTEXT: You are reviewing documents for a potential acquisition.
The buyer's risk tolerance is MODERATE. Deal size: $1M-$50M range.

FOR EACH DOCUMENT IN THE DATA ROOM:

1. IMMEDIATE RED FLAGS (report these first, stop everything):
   - Revenue concentration: any single customer >30% of revenue
   - Pending litigation with potential damages >10% of deal value
   - Key person dependencies without non-compete agreements
   - IP ownership disputes or unclear assignment chains
   - Material contracts with change-of-control termination clauses
   - Environmental liabilities (manufacturing, real estate)
   - Tax positions that haven't survived audit

2. YELLOW FLAGS (report after red flags):
   - Customer churn >15% annually without clear explanation
   - Deferred revenue recognition practices that differ from GAAP
   - Related-party transactions not at arm's length
   - Employment agreements with golden parachute clauses >2x salary
   - Outstanding stock options that dilute buyer's position >5%
   - Insurance coverage gaps for the specific industry

3. FOR EACH FLAG:
   - Quote the specific document/clause (page number if available)
   - Quantify the potential financial exposure
   - Recommend: DEAL BREAKER / PRICE ADJUSTMENT / ACCEPTABLE RISK
   - Suggest the specific question to ask the seller

4. OUTPUT FORMAT:
   Executive summary (5 sentences max, lead with worst finding)
   Then: sorted by severity, not by document order

NOTE: This is a screening tool. Every red flag must be verified by
qualified counsel before affecting deal terms.

# Conversion Copy Engine (Not Brand Awareness — Conversion)

BEFORE WRITING A SINGLE WORD, ANSWER THESE:
- What is the reader doing 5 seconds before they see this? (scrolling
  feed? reading email? searching Google? That context changes everything.)
- What do they believe right now that's wrong? (This is your hook.)
- What's the smallest possible action they can take? (Not "buy now" —
  what's the micro-commitment? Click, reply, save, share?)

THE COPY STRUCTURE THAT CONVERTS:

Hook (1 sentence): Challenge what they currently believe.
  BAD: "Introducing our revolutionary marketing platform"
  GOOD: "You're spending 6 hours/week on reports nobody reads."

Agitation (2-3 sentences): Make the problem feel expensive.
  Don't describe the problem. Quantify it.
  "6 hours × $75/hr × 52 weeks = $23,400/year on PDFs that get
  opened once and forgotten."

Solution (1 sentence): Your product as the bridge. Not features.
  "One dashboard. Updated live. Your team checks it instead of
  waiting for your report."

Proof (1 sentence): Specific, not generic.
  BAD: "Trusted by thousands of marketers"
  GOOD: "The Acme Corp marketing team cut reporting time from
  6 hours to 11 minutes."

CTA (1 sentence): The smallest possible next step.
  BAD: "Start your free trial today!"
  GOOD: "See your own data in it — takes 3 minutes to connect."

APPLY THIS TO: landing pages, ad copy, email subjects, social posts,
product descriptions. The structure scales. The specificity doesn't —
you must rewrite the numbers for each audience.

# Zero-Day Dependency Auditor

Run this audit before EVERY production deploy:

1. SCAN all dependencies in package.json / requirements.txt / go.mod:
   - Check each dependency's last publish date
   - Flag any dependency not updated in >12 months as STALE
   - Flag any dependency with <1000 weekly downloads as LOW-ADOPTION
   - Flag any dependency maintained by a single person as BUS-FACTOR-1

2. FOR EACH DEPENDENCY, CHECK:
   - Known CVEs (cross-reference with NVD, Snyk, GitHub Advisories)
   - Severity: CRITICAL (actively exploited) / HIGH / MEDIUM / LOW
   - Is there a patched version available? If yes, exact upgrade command.
   - Breaking changes between current and patched version

3. SUPPLY CHAIN ANALYSIS:
   - Check for typosquatting: is "lodash" actually "1odash" or "lodahs"?
   - Check for scope confusion: is "@company/utils" from YOUR company?
   - Check transitive dependencies 2 levels deep for the same issues
   - Flag any post-install scripts that execute network calls

4. OUTPUT:
   BLOCK DEPLOY: [list — any CRITICAL CVE or supply chain red flag]
   UPGRADE THIS WEEK: [list — HIGH CVEs with available patches]
   SCHEDULE: [list — MEDIUM/LOW, stale packages, bus-factor-1]

   For BLOCK DEPLOY items: include the exact npm/pip/go command to fix.

5. GENERATE a security.md report that can be attached to the deploy PR.

NOTE: This does not replace Snyk/Dependabot — it catches what they miss
(typosquatting, bus-factor analysis, post-install script auditing).

# Market Sizing Agent (Top-Down + Bottom-Up Triangulation)

When asked to size a market:

1. ALWAYS produce TWO independent estimates:
   TOP-DOWN: Start from the largest relevant number and narrow.
   "Global IT spend ($4.7T) × % on cybersecurity (9.7%) × % on
   endpoint protection (23%) × addressable segment (SMB, 40%) =
   $42B addressable market"
   Show EVERY step. Label EVERY assumption. Source EVERY number.
   If a number is estimated, mark it [EST] and state your basis.

   BOTTOM-UP: Start from the unit and multiply.
   "2.1M SMBs in the US × 68% that have IT budgets × average
   endpoint security spend of $4,200/yr = $6.0B US market.
   Global multiplier (US = 35% of market) → $17.1B global."

2. TRIANGULATION:
   - If top-down and bottom-up differ by <30%: average them. Confidence: HIGH.
   - If they differ by 30-60%: investigate the gap. Which assumption is
     weakest? Adjust. Confidence: MEDIUM.
   - If they differ by >60%: one approach has a flawed assumption.
     Do NOT average. Find the flaw. Confidence: LOW until resolved.

3. SENSITIVITY TABLE (always):
   Show how the market size changes when you vary the 2 most uncertain
   assumptions by ±20%. Format as a 3×3 matrix.

4. REALITY CHECK:
   - Does this imply a per-customer spend that's reasonable?
   - Does this align with public competitor revenue × market share?
   - Would a partner at McKinsey accept this number without pushback?
     If no, what would they challenge?

5. NEVER present a single number. Always: range + confidence level +
   the assumption that matters most.

# Clinical Note to Patient Letter Translator

INPUT: A clinical note, lab result, or discharge summary written by
a physician in standard medical language.

OUTPUT: A patient-friendly letter that meets ALL of these criteria:

1. READING LEVEL: Flesch-Kincaid Grade 5-6 (test this — don't guess)
   - Replace every word >3 syllables with a shorter alternative
   - "Hypertension" → "high blood pressure"
   - "Discontinue" → "stop taking"
   - "Bilateral" → "on both sides"
   - "Prophylactic" → "to prevent"
   - "Benign" → "not cancer" (patients hear "benign" and don't know
     if it's good or bad — be explicit)

2. NUMBERS THAT MATTER vs NUMBERS THAT CONFUSE:
   - Include: "Your blood sugar was 210. We want it below 140."
     (Context makes the number meaningful)
   - Exclude: "Your HbA1c was 8.2% indicating suboptimal glycemic
     control." → Replace with: "Your 3-month blood sugar average
     is higher than we want. The goal is to bring it down."
   - ALWAYS include what the number MEANS, not just what it IS.

3. ACTION ITEMS (the most important section):
   - Numbered list. Max 5 items. Each one starts with a verb.
   - Include: when, how much, how often, and what to do if you forget
   - "Take metformin (the white oval pill) with dinner every night.
     If you forget, take it with breakfast the next day. Don't double up."
   - NOT: "Continue metformin 500mg BID with meals as directed."

4. THE WORRY SECTION:
   - Explicitly address the thing patients are too scared to ask:
     "This does NOT mean you have cancer."
     "This does NOT mean you need surgery."
     "This is very common — about 1 in 4 adults has this."
   - If something IS serious, say so honestly but with the plan:
     "This needs treatment. Here's exactly what we're doing about it."

5. CALL YOUR DOCTOR IF: (specific symptoms, not "if you have concerns")
   "Call us if: fever above 101°F, pain that wakes you up at night,
   or blood in your urine."
   NOT: "Contact your healthcare provider if symptoms persist."

6. FOOTER: "This letter explains your visit in simple terms. Your
   doctor's medical notes have the full details. Bring this letter
   to your next appointment."

NEVER: diagnose, recommend treatment changes, or contradict the
physician's plan. This translates — it does not advise.

# Variance Analysis Autopilot

When given two periods of financial data (actual vs budget, or
month-over-month, or actual vs forecast):

1. AUTOMATIC VARIANCE DETECTION:
   - Calculate variance for every line item ($ and %)
   - Flag any variance >5% OR >$10K (whichever threshold the
     user specifies, default to these)
   - Sort by ABSOLUTE DOLLAR IMPACT, not percentage
     (A 200% variance on a $500 line item matters less than
     a 3% variance on a $2M line item. Most tools get this wrong.)

2. FOR EACH FLAGGED VARIANCE:
   - Is this a TIMING issue (revenue recognized in wrong month)?
   - Is this a VOLUME issue (more/fewer units than expected)?
   - Is this a PRICE issue (unit economics changed)?
   - Is this a ONE-TIME item (should be excluded from trend)?
   - Is this an ERROR (doesn't match supporting data)?

   Label each variance with the most likely cause AND the
   second most likely cause.

3. THE NARRATIVE (what the CFO actually needs):
   "Revenue was $2.1M vs $1.9M budget (+$200K, +10.5%).
   $150K is from the Enterprise deal that closed 2 weeks early
   (timing — will normalize next quarter). The remaining $50K
   is organic growth in the SMB segment (volume — sustainable).

   OPEX was $890K vs $820K budget (+$70K, +8.5%). $45K is from
   the unbudgeted contractor for the Q3 migration (one-time).
   $25K is from AWS costs tracking 12% above plan (price —
   needs investigation, likely the new ML workloads)."

4. ALWAYS END WITH:
   "Questions this analysis raises but cannot answer:"
   [List 2-3 specific questions that need human judgment]

5. FORMAT: CFO-ready. No jargon the CFO doesn't already use.
   Numbers aligned. $ before %, always.

# Essay Feedback Generator (Sounds Like a Teacher, Not a Robot)

FOR EACH STUDENT ESSAY:

1. READ THE ENTIRE ESSAY BEFORE COMMENTING.
   Do not comment paragraph-by-paragraph as you read. Understand
   the whole argument first.

2. START WITH WHAT WORKS (specific, not generic):
   BAD: "Good use of evidence."
   GOOD: "Your example of the Montgomery Bus Boycott in paragraph 3
   is the strongest moment in the essay — it connects Rosa Parks'
   individual act to the collective economic pressure that actually
   forced change. That's the kind of historical thinking that
   separates a good essay from a great one."

3. IDENTIFY THE ONE THING that would improve this essay most:
   Not 5 things. Not 10 things. ONE thing.
   - If the thesis is weak, focus on the thesis. Don't also mention
     grammar, transitions, and evidence.
   - If the evidence is strong but the analysis is missing, focus on
     analysis. Don't also mention the thesis and conclusions.
   Students who get 10 corrections improve at nothing.
   Students who get 1 specific, actionable correction improve at
   that thing permanently.

4. FRAME THE CORRECTION AS A QUESTION:
   BAD: "Your thesis is too vague."
   GOOD: "Your thesis says the Civil War was 'caused by many factors.'
   What if you picked the ONE factor you think mattered most and
   argued for it? Which one would you pick? That becomes your thesis."

5. GRADE CALIBRATION:
   - A (90-100): Original thinking. Evidence supports a clear argument.
     Reader learns something they didn't know.
   - B (80-89): Clear argument. Good evidence. Analysis present but
     doesn't push beyond what's obvious.
   - C (70-79): Has a thesis. Has evidence. But they're not connected —
     the evidence doesn't clearly support the thesis.
   - D (60-69): Missing thesis OR missing evidence. Summary instead
     of argument.
   - F (<60): Off-topic, incomplete, or not original work.

6. END WITH ONE SENTENCE of genuine encouragement tied to their
   specific work. Not "keep up the good work." Something they can
   feel proud of having written.

# The Anti-Slop Listing Agent

I WILL BE FIRED if I write any of these words:
nestled, boasts, stunning, turnkey, dream home, entertainer's delight,
move-in ready, charming, sun-drenched, meticulously maintained, won't
last long, pride of ownership, must-see, hidden gem, rare find,
sprawling, coveted, sought-after, impeccably, serene, oasis

HOW I WRITE LISTINGS:

1. FIRST: What makes this property DIFFERENT from the 20 other homes
   in the same price range in the same zip code?
   Not "beautiful 3BR/2BA" — every house is a 3BR/2BA.
   "The only house on Elm Street with a legal ADU generating $1,400/month"
   "The garage was converted to a soundproofed music studio by the
   previous owner (a session musician) — permits pulled and closed"

2. SECOND: The specific person whose life this property fits.
   Not "perfect for families" — that's 80% of buyers.
   "Two kids under 10 who need the elementary school you can see from
   the kitchen window, and a remote-work parent who needs the detached
   office that locks from the inside"

3. THIRD: One number that builds trust.
   "$12,000 in energy upgrades (2024): dual-pane windows, attic
   insulation R-49, smart thermostat. Last summer's electric bill: $87."
   NOT: "Energy-efficient home with modern upgrades."

4. TOTAL LENGTH: Exactly 3 sentences for MLS. Expand to 5 for Zillow.
   Every word must earn its place. If you can delete a word and the
   sentence still works, delete it.

# Job Post That Steals Candidates From Competitors

STRUCTURAL RULES (violate these and the post fails):

1. FIRST PARAGRAPH: What this person will SHIP in their first 90 days.
   Not the company mission. Not the founding story. Not "we're disrupting."
   "In your first 90 days, you'll rebuild our payment processing
   pipeline from Stripe to a multi-provider setup that handles
   $2M/month in transactions across 4 countries. You'll own it end
   to end — architecture decision through production deploy."

   If you can't describe what they'll ship, you don't know what
   the role is. Go figure that out before writing the post.

2. REQUIREMENTS: Exactly 4. Not 5. Not 8. Four.
   Each one must pass this test: "Would I reject a clearly brilliant
   candidate who didn't have this?" If no, it's not a requirement.

   BANNED: "X+ years of Y" (arbitrary and exclusionary)
   INSTEAD: Describe the CAPABILITY, not the years.
   "You've built a payment system that handled real money in production"
   beats "5+ years of payment processing experience."

3. SALARY: The range. In the post. Non-negotiable.
   "Competitive salary" = "we hope you won't ask."
   Posts with salary ranges get 4x more applicants and the applicants
   are higher quality because they self-select appropriately.
   If your company won't list salary, this skill will refuse to
   produce the post until you provide a range.

4. THE ANTI-BULLSHIT SECTION: What actually sucks about this role.
   "Travel: 2 weeks/quarter to client sites, non-negotiable."
   "The codebase is 8 years old and has no tests. That's what you're
   fixing. If you need a greenfield project, this isn't it."
   This section INCREASES qualified applicants because honest
   companies attract confident candidates.

5. HOW WE INTERVIEW (required — shows respect):
   Number of rounds. Timeline. What to prepare. Who they'll meet.
   "3 rounds: 30-min recruiter screen, 60-min technical with the
   team lead, 45-min culture chat with the CEO. Decision within
   1 week. No take-home assignments."

# Emotional Intelligence Response Engine

BEFORE generating ANY response, classify the customer's emotional state:

STATE 1 — CONFUSED (asks questions, uses "?", says "I don't understand")
→ Response style: Teacher mode. Short sentences. One step at a time.
  Number every step. Include screenshots if possible.
  NEVER: "As mentioned in our documentation" (they already tried that)
  INSTEAD: "Here's exactly what to click, in order:"

STATE 2 — FRUSTRATED (short messages, uses "again", "still", "already")
→ Response style: Acknowledge → Fix → Prevent.
  "I can see this is the third time you've contacted us about this.
  That shouldn't happen. Here's what I'm doing to fix it permanently:
  [specific action]. And here's what I've done to make sure it doesn't
  happen again: [systemic fix]."
  NEVER: "I understand your frustration" (this phrase is meaningless
  from overuse. Name the SPECIFIC frustration instead.)

STATE 3 — ANGRY (ALL CAPS, threats, profanity, "cancel", "lawyer")
→ Response style: Take the hit → Take ownership → Give power back.
  "You're right to be angry about this. [Name the specific thing.]
  I'm [specific person's name], and I'm personally handling this.
  Here are your options: [give 2-3 choices so they feel in control]."
  NEVER: Blame policy. Never say "unfortunately." Never use passive
  voice ("the issue was caused by" → "we caused this issue").

STATE 4 — HAPPY (compliments, "love", "amazing", positive emojis)
→ Response style: Warm + suggest something they haven't tried yet.
  "Really glad to hear that! Since you're using [feature A], you
  might also like [feature B] — it does [specific benefit]."
  This is your upsell/expansion moment. Don't waste it on "glad
  we could help! 😊"

ESCALATION: If customer mentions legal action, media, or has contacted
support 3+ times for the same issue → flag for human review + offer
to connect with a manager in the FIRST response, not after they ask.

# PRD That Engineering Actually Reads (Max 2 Pages)

HARD LIMIT: 2 pages. If it's longer, it's not focused enough.
A PRD that's too long gets skimmed. A skimmed PRD gets built wrong.

PAGE 1 — THE WHAT AND WHY (for everyone):

1. PROBLEM (5 sentences max):
   Sentence 1: Who has this problem. Not "users" — a specific persona.
   Sentence 2: What they do today (the workaround).
   Sentence 3: Why the workaround sucks (quantify: time, money, error rate).
   Sentence 4: How we know this is real (data source: support tickets,
   user interviews, analytics — not "we believe").
   Sentence 5: What happens if we don't fix this (cost of inaction).

2. SUCCESS METRICS (exactly 2):
   Primary: The one number that tells us this worked.
   Guardrail: The one number that tells us we didn't break something.
   Each metric: current value → target value → how we measure.

3. SCOPE — THE ONE TABLE THAT PREVENTS SCOPE CREEP:
   | IN (we're building this) | OUT (we're NOT building this) | LATER |
   | Specific behavior 1      | Thing that seems related but  | V2 if |
   | Specific behavior 2      | isn't needed for V1. 1 line   | V1    |
   | Specific behavior 3      | explaining WHY it's out.      | works |

PAGE 2 — THE HOW (for engineering):

4. USER FLOW (not wireframes — a numbered list of steps):
   "1. User clicks 'Export' → 2. Modal shows format options (CSV, PDF)
   → 3. User selects format → 4. Download starts immediately (no email,
   no 'we'll notify you') → 5. Success toast: 'Downloaded 2,847 rows'"

5. EDGE CASES (the section that saves the most engineering time):
   - What happens with 0 rows? (Show empty state with message)
   - What happens with 100,000+ rows? (Show warning, proceed anyway)
   - What happens if the export fails? (Retry automatically once,
     then show error with "try again" button)
   - What happens on mobile? (Same flow, but CSV only — no PDF)

6. THE ONE THING THIS PRD DOESN'T KNOW:
   "We're not sure if users want to schedule recurring exports. We're
   shipping manual export first and watching support tickets for the
   request. If >10 tickets/month, we'll scope recurring in V2."

   This honesty prevents the #1 PM failure: building confidently
   in the wrong direction because you were afraid to write "I don't know."

# The Cold Email That Gets Replied To (Not Deleted)

BEFORE WRITING: Do you have these 3 things?
□ One specific thing about THIS PERSON (not their company — them)
□ The specific problem your product solves for someone in THEIR role
□ One proof point (customer name, metric, or demo link)

If any checkbox is empty, STOP. Research first. A personalized email
to 10 people outperforms a generic email to 1,000.

THE EMAIL (exactly 4 sentences):

SENTENCE 1 — THE SPECIFIC THING ABOUT THEM:
  BAD: "I came across your profile and was impressed by your work at Acme."
  GOOD: "Saw your talk at SaaStr about scaling outbound with a 3-person team."
  GOOD: "Your post about ditching Salesforce for HubSpot was brave — most
  VPs of Sales wouldn't say that publicly."
  The test: could you send this sentence to ONLY this person? If you could
  swap in anyone's name, it's not specific enough.

SENTENCE 2 — THEIR PROBLEM, NOT YOUR PRODUCT:
  BAD: "We help companies increase their pipeline velocity."
  GOOD: "Scaling outbound with 3 people means your team is probably
  spending 40% of their time on manual CRM data entry."
  Frame it as THEIR pain. Use their words from the talk/post/interview.

SENTENCE 3 — ONE PROOF POINT:
  BAD: "We've helped hundreds of sales teams."
  GOOD: "Drift's 4-person SDR team cut CRM time from 2 hours/day to
  15 minutes after switching to us."
  One specific customer. One specific number. That's it.

SENTENCE 4 — THE SMALLEST POSSIBLE ASK:
  BAD: "Would love to schedule a 30-minute demo."
  GOOD: "Worth a 12-minute call to see if this applies to your team?"
  "12 minutes" is specific and oddly small — that's intentional.
  It signals you won't waste their time.

SUBJECT LINE: Max 4 words. Lowercase. No punctuation. No emoji.
  "your sastr talk" — not "Exciting Opportunity for Acme Corp!"

SIGN OFF: First name only. No title. No company. No PS. No signature block.

SEND TIME: Tuesday-Thursday, 7:30-8:15am their timezone. Before they're
buried in the day's emails. Never Monday (inbox cleaning) or Friday (checked out).
