| Skill | What it does | Install |
|---|---|---|
| Account research brief | You need to research a target company before outreach, a first call or an account plan: "research this account", "what should I know about Acme before the call", "find a reason to reach out". | --skill account-research-brief |
| Buyer persona builder | You need B2B buyer personas that sales and marketing will actually use: before writing outreach to a new title, when messaging feels generic, or when a deal stalls because the wrong person is engaged. | --skill buyer-persona-builder |
| Competitor teardown | You need to understand a competitor well enough to beat them: a deal is going head to head, a new competitor appeared, positioning needs a refresh, or reps keep losing on the same objection. | --skill competitor-teardown |
| Customer interview guide | You want to learn from customers or prospects in a structured interview: "write customer interview questions", "voice of customer research", "why did customers buy", "jobs to be done interviews". | --skill customer-interview-guide |
| ICP builder | You need to define or sharpen an ideal customer profile (ICP) for B2B sales: starting outbound, the reply rate is low, the pipeline is full of bad-fit deals, or leadership asks who we should really sell to. | --skill icp-builder |
| Prospect research brief | You need to research a specific person before reaching out or meeting them: "look up this prospect", "what do I say to Jane", "find a personalised first line". | --skill prospect-research-brief |
| TAM, SAM and SOM calculator | You need a credible market size for a B2B product: a board or investor deck, territory planning, deciding which segment to attack, or checking whether outbound has enough accounts to sustain a quota. | --skill tam-calculator |

|---|---|---|
| Account tiering | You need to decide which accounts get the most effort: "tier my account list", "which accounts should get 1:1 research", "prioritise my territory", "score these companies". | --skill account-tiering |
| Buying committee mapper | A B2B deal or target account needs more than one contact: "who else should I talk to", "map the buying committee", "multi-thread this deal", or a single-threaded deal is at risk. | --skill buying-committee-mapper |
| Lead list builder | You need a B2B lead list for outbound: "build me a list of 500 heads of operations at logistics companies", "find leads for this campaign", "who should we target next". | --skill lead-list-builder |
| Lead scoring model | You need a lead scoring model that sales trusts: inbound leads pile up unworked, marketing and sales argue about MQL quality, or reps chase the wrong leads first. | --skill lead-scoring-model |
| List cleaning | A prospect or contact list needs cleaning before outreach or import: "clean this CSV", "dedupe my leads", "fix the names and titles", "why are my bounces high". | --skill list-cleaning |

| Buying signal scoring | You track buying signals and need to decide which ones deserve outreach today: "which accounts are in market", "prioritise these signals", "build a signal-based selling system". | --skill buying-signal-scoring |
| Funding signal outreach | A target company announces a funding round, acquisition or major investment and you want to reach out: "they just raised a Series B", "write a funding congratulations email that is not generic", "use funding as a buying signal". | --skill funding-signal-outreach |
| Hiring signal outreach | A target company is hiring for roles your product supports or replaces: "they are hiring SDRs", "use job postings as a buying signal", "write outreach based on their job listing". | --skill hiring-signal-outreach |
| Job change plays | A contact changes jobs: a champion or happy user joins a new company, a new leader starts at a target account, or a key contact leaves a customer. | --skill job-change-plays |
| Post engagement outreach | People engage with LinkedIn posts (yours, your team's, a competitor's or an industry voice's) and you want to turn that engagement into conversations: "reach out to people who liked our post", "warm outreach from post engagers", "turn commenters into leads". | --skill post-engagement-outreach |
| Tech stack signal outreach | A company's technology choices are a buying signal for you: "target companies using X", "they just added a tool we integrate with", "technographic outreach", "companies switching away from a competitor". | --skill tech-stack-signal-outreach |
| Website visitor follow-up | You know which companies visited your website and want to follow up without being creepy: "turn website visitors into meetings", "who should we contact from yesterday's visitors", "write outreach for high-intent visits". | --skill website-visitor-follow-up |

| First line personalization | You need personalised first lines (icebreakers) for cold emails or LinkedIn messages at scale: "write personalised openers for this list", "add a custom first line for each lead", "make my outreach feel 1:1". | --skill first-line-personalization |
| Follow-up email writer | You need to follow up after no reply, after a meeting, after a proposal or after a prospect went quiet: "write a follow-up email", "they ghosted me", "follow up after the demo". | `--skill |
