Value Prop Lister is a Claude Skill that reads a company’s website, pitch decks, or product documents and turns scattered marketing copy into a structured value proposition inventory. Instead of a vague list of “benefits,” you get every claim sorted, ranked, and tied to a specific buyer.

Claude Skills themselves are just Markdown files (.md) packed with instructions for a specific task. Load one into a conversation, and Claude follows that playbook instead of guessing at what you want. (How to Use lemlist Claude Skills (.md Files) in Claude | Step-by-Step Guide)

Here’s what the skill actually pulls out of a page of copy, and where it puts it:

You end up with a working document rather than a highlight reel. That distinction matters once you use this for competitive research, because one missed claim can throw off an entire positioning strategy.

Most teams find out about competitor messaging changes by accident. Someone spots a new landing page, drops a screenshot in Slack, and the conversation dies within the hour.

Competitors keep moving in the background. They reposition after funding rounds, ship features, adjust pricing, and none of it shows up on your radar unless someone happens to notice.

Without a repeatable process, your own messaging drifts quietly from what’s actually happening in the market. You might still be countering a claim a competitor dropped two quarters ago.

A structured audit fixes the timing problem. Run it on a regular cadence, and you’ll catch a new “AI-powered” angle, a dropped compliance claim, or a case study aimed squarely at your ICP while it’s still fresh.

There’s an internal payoff too. When the audit lives in one document, your SDRs, AEs, and marketing team work from the same competitive picture instead of relying on memory or an outdated battle card.

Each Claude Skill is a plain .md file, not code you run. Value Prop Lister lives in lemlist’s open-source Claude Skills repository, at l3mpire/claude-skills/value-prop-lister/SKILL.md. Download the file or copy the raw contents directly.

For a one-off session, drag the file straight into a Claude conversation window. If you’re on Claude Pro or Team, add it to a Claude Project instead, so the skill stays loaded and you won’t re-upload it every time you open a new chat. (How to Use lemlist Claude Skills (.md Files) in Claude | Step-by-Step Guide)

Paste in a short piece of company copy, maybe an “About” paragraph or a homepage hero section, and ask Claude to extract the value propositions. If categories, persona mappings, and tier rankings come back, the skill loaded correctly.

If Claude returns a generic summary instead, something didn’t load. Re-upload the file and confirm it shows up in Project Knowledge before trying again.

Pick one competitor to start. Gather their homepage copy, product pages, pricing page, and a couple of case studies (a PDF deck or G2 profile works fine too).

Tip: Copy-paste page content into a single document rather than pointing Claude at live URLs. Pasted text reads more reliably, and you’ll skip the formatting issues that come from fetching pages directly.

Paste the materials into your Claude conversation where the skill is loaded, and add a line of context: “This is the website copy for [Competitor], a [category] tool targeting [audience].” That context helps Claude tell real value claims apart from filler marketing language.

You’ll get back a structured inventory with every claim categorized, ranked, and mapped to a persona. Spot-check a few entries against the source material.

Some props might feel inferred rather than directly stated. Flag those before building any messaging around them.

Apply the same process to your own site and decks. This is where the real value shows up: a side-by-side view of where your messaging overlaps with theirs, where you’re ahead, and where they’re making claims you haven’t addressed at all.

Knowing what to expect from the output makes it easier to use once it lands.

The “Gaps and recommendations” section tends to be the most useful part for competitive work. It flags claims a competitor makes without backing evidence, which gives you an opening to counter-position, and it surfaces strong proof points buried in a case study instead of on the homepage.

Once you have the inventory, group the props by the role each one speaks to. Different people care about different outcomes, and leading with the wrong angle makes even strong copy fall flat.

The persona mapping in the output does most of this grouping already. When you draft an outbound sequence, lead with the persona’s top-tier prop, and save the supporting ones for later touches.

Cross-reference a competitor’s claims with your own strengths. If their prop reads generic (“save time with automation”), write copy that names the same pain with a real number (“cut campaign launch from 45 minutes to under 2”). The audit tells you exactly which claim to go after.

Use the audit to decide which angle opens each sequence. Your first touch can speak to the assumption a prospect probably already holds based on what their current vendor promises, and your follow-ups can introduce differentiators they haven’t seen yet.

If you’re running multichannel campaigns, a tool like lemlist lets you build these sequences across email, LinkedIn, and calls from one workflow, so each channel carries a different angle from the audit instead of repeating the same line three times.

A value prop only lands when it connects to something real about the prospect. Enrichment data (LinkedIn activity, company news, tech stack, hiring signals) turns a generic claim into something specific.

lemlist’s enrichment agents pull that context from LinkedIn, company websites, and CRM data automatically as leads enter a campaign. The audit tells you what to say. Enrichment tells you how to make it personal.

The same value prop won’t perform the same way on email, LinkedIn, and cold calls. The channel fit tags in the inventory give you a starting hypothesis, and tracking reply rates by angle tells you which one actually deserves the earlier touch.

Value Prop Lister is one skill inside lemlist’s Claude Skills Hub, a free library of 40+ skills built to turn Claude into a GTM assistant. (How to Use lemlist Claude Skills (.md Files) in Claude | Step-by-Step Guide) It works fine on its own, but it connects naturally to a few others in the library.

After extracting a competitor’s value props, the Persona Definer skill can turn those findings into contact-level targeting criteria. Feed that into List Builder to find matching leads across lemlist’s 650M+ database, or run Buying Trigger Analysis to time outreach around funding news, hiring activity, or tool changes that echo the angles your audit surfaced.

Pick one competitor, paste their homepage and features page into Claude with the skill loaded, and see what comes back. You’ll have a structured, ranked inventory in a few minutes, work that would otherwise eat an afternoon.

Once you’ve spotted the gaps worth testing, the next step is building the campaign around them. lemlist brings lead discovery, enrichment, multichannel sequencing, and deliverability into one place, so what you learn from the audit turns into outreach without extra tools in between.

Yes. Running the skill on your own website and decks produces the same structured inventory. Comparing that output against a competitor’s is usually where messaging gaps and differentiation opportunities show up.

Claude Pro and Team plans let you add skill files to a Project so they stay loaded across conversations. (How to Use lemlist Claude Skills (.md Files) in Claude | Step-by-Step Guide) On the free tier, you can still paste the SKILL.md contents into a conversation, though you’ll paste it again each session.

Plain pasted text works, and so do PDFs and plain text files. Copied webpage content is usually fine too. What matters more than format is how complete the source material is.

Re-run it whenever a competitor ships a major feature, redesigns their site, or changes pricing. For most markets, a quarterly cadence catches the changes that matter without turning into busywork.

Value Prop Lister is a Claude Skill that scans a company’s website, decks, or documents and produces a structured value proposition inventory , categorized by outcome type, mapped to buyer personas, and tagged with channel fit for outreach. Claude Skills are structured Markdown files (.md) that contain detailed instructions, context, and best practices for a specific task. When you load a skill into a Claude conversation, it’s like handing an expert playbook to your AI, producing higher-quality, more consistent outputs than a generic prompt ever could. (How to Use lemlist Claude Skills (.md Files) in Claude | Step-by-Step Guide)

Where a generic prompt might return a vague list of “benefits,” Value Prop Lister follows a defined extraction framework. It looks across homepage copy, product pages, pricing, case studies, and testimonials, then classifies every proposition it finds into one of seven types:

The output also groups propositions by persona (so an SDR sees different lead messages than a VP of Sales), ranks them into tiers based on strength and proof, and suggests copy-ready versions for email, LinkedIn, and cold calls. You get a complete, usable inventory rather than a wall of bullet points.

Most teams check competitor messaging reactively. Someone spots a new landing page, screenshots it in Slack, and the thread dies within a day. Meanwhile, competitors reposition after funding rounds, ship new features, or change pricing. Without a repeatable audit process, your outbound messaging slowly drifts from what competitors actually claim, and your differentiation weakens without anyone noticing.

A structured audit fixes the timing problem. When you extract and catalog every competitor’s stated value props on a regular cadence, you can spot shifts early: a new “AI-powered” angle, a dropped compliance claim, a freshly added case study that targets your exact ICP. Those details change how you write opening lines, how you handle objections, and which proof points you lead with.

The second benefit is internal alignment. A documented inventory means your SDRs, AEs, and marketing team reference the same competitive picture instead of working off stale battle cards or personal memory.

Each skill is a .md file you download (How to Use lemlist Claude Skills (.md Files) in Claude | Step-by-Step Guide) from lemlist’s open-source Claude Skills repository on GitHub. For Value Prop Lister, the file lives at l3mpire/claude-skills/value-prop-lister/SKILL.md. Click “Download” or copy the raw file contents.

You have two options. For one-time use, drag the SKILL.md file directly into a Claude conversation window. If you use Claude Pro or Team, you can add skill files to a Claude Project, which means the skill is always loaded and you don’t have to re-upload it every time you start a new conversation. (How to Use lemlist Claude Skills (.md Files) in Claude | Step-by-Step Guide)

Paste a short snippet of company copy (an “About” paragraph or a homepage hero section) and ask Claude to extract value propositions. If the structured inventory output appears with categories, persona mappings, and tier rankings, the skill is loaded correctly. If Claude returns a generic summary instead, re-upload the file and confirm it appears in Project Knowledge.

Start with one competitor. Gather their homepage copy, product feature pages, pricing page, and two or three case studies. PDF pitch decks or G2 profile descriptions work too. The richer the input, the more complete the extraction.

Upload or paste the collected materials into your Claude conversation where the skill is loaded. Add a brief context line: “This is the website copy for [Competitor Name], a [category] tool targeting [audience].” That context helps Claude distinguish between genuine value claims and filler marketing language, which improves extraction accuracy.

The skill returns a structured value proposition inventory with every prop categorized, ranked, and mapped to personas. Spot-check a handful of claims against the source material. Flag any propositions that feel inferred rather than directly stated, because you’ll want to verify those before building competitive messaging around them.

Apply the same process to your own website and sales decks. The side-by-side comparison is where the real value sits: you can see exactly where messaging overlaps, where you hold a differentiation advantage, and where your competitor makes claims you haven’t addressed at all.

Before you run the skill, it helps to know what the output contains. Here’s the structure:

The “Gaps and recommendations” section is particularly useful for competitive work. It flags claims the competitor makes without backing evidence (which you can counter-position against) and strong proof points buried in case studies that haven’t made it to the homepage yet.

Once you have the inventory, group propositions by the role they resonate with most. Different personas care about different outcome types, and leading with the wrong angle makes even good copy feel irrelevant.

The persona mapping in the inventory output makes this grouping fast. When you draft outbound sequences, use the persona’s top-tier props as your opening angle, and hold supporting props for follow-up touches.

Cross-reference your competitor’s claims with your own strengths. Where a competitor’s prop is generic (“save time with automation”), write copy that addresses the same pain with specifics from your product (“cut campaign launch from 45 minutes to under 2 minutes”). The audit tells you exactly which claims to counter.

Use the audit to choose which messaging angle leads each sequence. Your first touch can address the prospect’s most likely assumption based on what their current vendor promises. Follow-up emails can introduce differentiators they haven’t seen.

If you’re running multichannel campaigns, tools like lemlist let you build these sequences across email, LinkedIn, and calls from a single workflow so each channel carries a different angle from the audit rather than repeating the same message.

A value prop only lands when it connects to the prospect’s actual situation. Enrichment data (LinkedIn context, company news, tech stack, hiring activity) makes each proposition specific rather than theoretical. When you know what a prospect’s current vendor claims, you can counter-position in the opening line.

lemlist’s enrichment agents pull context from LinkedIn profiles, websites, and CRM data, so personalization happens automatically as leads enter a campaign. The value prop audit tells you what to say. Enrichment data tells you how to tailor it.

Different value propositions perform differently on email vs. LinkedIn vs. cold calls. The channel fit tags from the inventory give you a starting hypothesis. Track reply rates per angle, rotate underperforming props out, and promote winning angles to earlier touches.

Yes. Running the skill against your own website and decks produces the same structured inventory. The comparison between your output and a competitor’s output is where you spot messaging gaps, missing proof points, and differentiation opportunities.

If you use Claude Pro or Team, you can add skill files to a Claude Project so the skill is always loaded. (How to Use lemlist Claude Skills (.md Files) in Claude | Step-by-Step Guide) On the free tier, you can still paste the SKILL.md contents directly into a conversation, though you’ll have to re-paste each session.

You can paste text directly or upload PDFs and plain text files. Copied webpage content works well. The skill processes any readable text input that Claude can handle, so the format is less important than the quality and completeness of the source material.

Re-run the audit whenever a competitor ships a major feature, redesigns their website, or changes pricing. For most markets, a quarterly cadence catches the meaningful shifts without creating busywork.
