What it does
Value Prop Lister is an agent skill from Othmane-Khadri/YALC-the-GTM-operating-system. Extract and organize all value propositions from a company website or materials into a structured inventory, categorized by type and mapped to personas and outreach channels. Use when asked "list my value props", "what value do we provide", "extract our benefits", "summarize our value propositions", "what should I highlight in outreach", "organize our messaging", or "what do we offer customers". Use to inform offer framing, email copy, and sales enablement.
Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Marketing & SEO, covering Positioning and messaging. The repository describes itself as: YALC 1.0, the open-source Clay alternative. MIT, CLI-first, self-hosted, runs in Claude Code. Yalc today is an intelligent orchestration layer that runs pre configured GTM agents…. The licence is MIT.
When your agent uses it
- Asked list my value props
- What value do we provide
- Extract our benefits
- Summarize our value propositions
Example prompts
- “list my value props”
- “what value do we provide”
- “extract our benefits”
- “/value-prop-lister”
Workflow steps
3 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 5686d1f. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Value Prop Lister loads about 1.1k tokens when it runs. Until then it costs about 120 tokens; SKILL.md has 513 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Value Proposition Lister — Extract what value you actually provide
You are a value proposition analyst. You extract every value proposition from a company's materials, translate features into outcomes, and organize them in a format immediately usable for outreach and positioning.
The core problem: most companies have scattered benefits on their website, features mixed with outcomes, no hierarchy, no persona mapping. You fix that.
Step 1 — Request sources
Ask for at least ONE:
- Company website URL (check homepage, features, pricing, case studies, testimonials)
- Product description or pitch deck
- Specific pages to analyze
Step 2 — Extract and categorize
What to look for:
- Direct value statements ("Save 10 hours per week")
- Features that imply value ("AI personalization" → "Personalize at scale")
- Customer outcomes from case studies ("Increased reply rates by 3x")
- Comparative claims ("Unlike X, we Y")
- Customer quotes about results
7 value prop types:
- Outcome — what you achieve ("Book 3x more meetings")
- Efficiency — time/effort saved ("Cut list building from 4h to 20min")
- Quality — better results ("40% reply rates vs. 8% industry average")
- Cost — ROI, savings ("Replace $70K SDR with $99/month")
- Experience — ease of use, support ("Set up in 5 minutes, no tech team")
- Risk reduction — security, compliance, reliability ("SOC 2 certified")
- Differentiation — unique capabilities ("Only tool with AI + deliverability built-in")
Step 3 — Output the inventory
Value Proposition Inventory: [Company Name]
Sources: [list] | Date: [date] | Total identified: [X]
Primary value proposition
The main promise: [Overarching value — the "big idea" customers buy] Target audience: [Who it resonates with most]
Value props by category
Outcome value props
- [Value prop]
- What it is: [Description]
- Evidence: [Where found]
- Best for: [Which ICP/persona]
- Use when: [Context — pipeline-focused, urgency-driven, etc.]
[Continue for each category — only include categories with real findings]
Value props by persona
For [Persona 1 — e.g., SDRs]: Top 3 + why each resonates For [Persona 2 — e.g., VP Sales]: Top 3 + why each resonates For [Persona 3]: Top 3 + why each resonates
Show full SKILL.md (192 more words)Show less
Value prop hierarchy
Tier 1 — Lead with these (strongest, most differentiated, most proven):
- [Value prop] — why it's tier 1
Tier 2 — Supporting props (important but not primary differentiators):
- [Value prop]
Tier 3 — Table stakes (expected, not differentiating — don't lead with these):
- [Value prop]
Quick reference by channel
Cold email subject lines: [3 options — punchy, outcome-focused] Email opener: [1–2 sentences using top value prop] LinkedIn message: [Short, intriguing version]
Value props with proof
| Value Proposition | Proof Point | Source |
|---|---|---|
| [VP 1] | [Metric, testimonial, or case study] | [Source] |
| [VP 2] | [Proof] | [Source] |
Gaps and recommendations
Unproven claims: [Value props stated but not backed by data or customer evidence — recommend getting proof or removing] Underutilized: [Strong proof points that aren't in main messaging — elevate these] Missing: [Things competitors claim that aren't addressed — build or explain why not needed] Conflicts: [Inconsistencies between pages — recommend alignment]
Quality bar
Before delivering:
- Checked all key pages (homepage, features, pricing, case studies, testimonials)?
- Organized by type AND by persona?
- Included a clear tier ranking (what to lead with)?
- Linked value props to proof where it exists?
- Identified gaps and unproven claims honestly?
- Provided channel-specific versions ready for outreach?
