ONE LIBRARY
FOR THE ENTIRE PROMPT STACK.

Reviews a PR like a senior who optimizes for the next reader, not style nits.

Write an ADR that future-you will still understand in 18 months.

Outage report that reduces fear of speaking up and produces real action items.

Reach a busy founder without AI-slop tone. Four lines, one ask, no hedging.

Monthly update that earns trust by being honest about misses.

Announce a B2B SaaS launch in the YC style. Sharp lede, two metrics, one founder quote.

Ask the questions that surface pain, not features. Seven questions, no leading the witness.

Set pricing for a new B2B SaaS. Three tiers, unit economics, anchor + decoy logic.

Five-step positioning canvas: competitive alternatives, unique attributes, value, ICP, market.

Distill 12 customer calls into themes, frequencies, and a top-3 list that survives committee.

Hook earns the open. 3 curated items, one personal note, soft CTA.

Hook → reframe → 3 acts → payoff. Designed to hold 60%+ retention.

Announce a feature ship. Lead with the job it does, not the feature name.

Submit a talk that reviewers can't skip. Hook, claim, 3 takeaways, audience.

Compress a 30-page paper into 5 lines + 4 structured takeaways.

Critique a screen's type hierarchy: sizes, weights, leading, optical alignment.

An empty state that teaches the user what to do next. Not just a blank screen.

Error messages that respect the user. Specific, actionable, never condescending.

Acknowledge, explain, propose, follow up. Don't roll over.

Reply to a SIG Lite questionnaire using your SOC 2 report. Cite controls.

Take wishful OKRs and turn them into bets you can actually grade.

Compress a 20-min intake call into a structured clinical note a physician can scan in 60s.

Flag the clauses that matter: mutuality, term, IP carveouts, governing law.

Teach a concept by asking, not telling. Five questions ordered by difficulty.

Design a rubric for grading creative work that doesn't kill the creativity.

Write a policy doc (e.g., remote work, AI usage) that's clear, lived, and won't gather dust.

Sell without lying. Lead with the JTBD. Three specs. Risk reversal.

Sell the moment, not the square footage. 3 paragraphs.

Write a listing that wins the algorithm AND the buyer. Keywords, bullets, A+ copy.

Decision memo that earns the meeting. Context, options, recommendation, risks.

Build a board deck that tells one story. Not 40 slides of metrics.

Design a 5-stage interview loop that surfaces real signal, not theater.

Have a hard performance conversation that respects both people. Script + recovery plan.

Build a 10-slide deck investors don't skim. Inevitability, wedge, traction, ask.

Run a pre-mortem on a decision. Imagine it's failed; trace back the most likely cause.

Build a system prompt for a custom agent that doesn't drift. Role, constraints, format.

Deliver feedback that the recipient can hear AND act on. Specific, kind, future-focused.

Design an A/B test that's powered, falsifiable, and shippable. Hypothesis to readout.

Argue a contrarian position credibly. Steelman opposition, then dismantle.

5-email onboarding that gets users to first value, not just first login.

Write a spec that fits on one page and ships in one sprint.

Diagnose why a prompt is producing poor output and fix it.
