Workflow
When this skill is invoked, the user provides two inputs: a prospect brief (named person, company, role, and 2-4 specific recent facts such as a funding round, job posting, product launch, or public quote) and a seller's offer (what you sell and the core value proposition). Your job is to write a 3-touch outbound sequence that a real human sales rep would be proud to send.
Step 1 — Ingest inputs
Read both sections carefully:
- Prospect brief: Extract the prospect's name, title, company, and every specific fact provided. Flag any fact that is vague, inferred, or not explicitly stated — do not use it.
- Seller's offer: Identify the exact product or service and the concrete value it delivers. Do not embellish.
Step 2 — Select 3 distinct angles
From the specific facts in the brief, choose 3 that each open a different conversation angle. Good angles:
- A recent company event (funding, launch, acquisition, reorg)
- A stated strategic priority (job posting signals, public roadmap mention)
- A personal/public statement (podcast quote, LinkedIn post, conference talk)
- A market move (competitor action they responded to, category shift)
Each touch will anchor on exactly one angle. Do not reuse angles across touches.
Step 3 — Write the sequence
For each touch, produce:
- A Subject line — specific, not generic; references the angle directly
- A Body — 3-5 sentences maximum; opens with the specific fact, connects it to a plausible pain or priority, states what you offer in one sentence, closes with a single soft CTA
Tone rules:
- Write like a thoughtful peer, not a vendor
- No superlatives ("amazing", "revolutionary", "best-in-class")
- No false urgency ("limited time", "before it's too late")
- No fabricated claims ("I noticed you're struggling with X" — unless X is explicitly in the brief)
- One CTA per touch; keep it low-friction (a question or a short call, not a demo demand in touch 1)
Touch sequencing:
- Touch 1 (Day 1): Lead with the strongest, most specific fact. Introduce yourself and your offer briefly. CTA is a soft question.
- Touch 2 (Day 5-7): Different angle. Add a small piece of value (a relevant observation, a resource, a data point from your domain). CTA offers a specific short call.
- Touch 3 (Day 14): Breakup tone — low pressure, leave the door open. Reference the original reason you reached out. CTA is a yes/no permission ask.
Step 4 — Self-check against the rubric
Before finalizing, verify every item in the rubric below. If any item fails, revise the relevant touch.
- Exactly 3 touches are present
- Each touch references a specific fact that appears verbatim or paraphrased from the brief — not inferred or invented
- No fabricated claims about the prospect's internal state, problems, or situation
- Each touch has exactly one CTA
- Tone is human and conversational — no clichés, no manipulative urgency
- Subject lines are specific and non-generic
- Each body is 3-5 sentences
