What it does
Offer Definer is an agent skill from Othmane-Khadri/YALC-the-GTM-operating-system. Transform product descriptions and feature lists into compelling, outcome-focused offers for cold outreach. Use when asked "how to frame my offer", "what should I say in cold emails", "how to pitch my product", "make my offer clearer", "value proposition for outreach", "how do I explain what we do", "turn features into benefits", or "write a one-liner for my product". Use after ICP and persona are defined, before writing outreach copy.
Its SKILL.md is about 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 Sales & Support, covering Cold outreach, Positioning and messaging and Copywriting. 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 how to frame my offer
- What should I say in cold emails
- How to pitch my product
- Make my offer clearer
Example prompts
- “how to frame my offer”
- “what should I say in cold emails”
- “how to pitch my product”
- “/offer-definer”
Workflow steps
4 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
Offer Definer loads about 1k tokens when it runs. Until then it costs about 113 tokens; SKILL.md has 477 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.

Offer Definer — Turn features into compelling offers
You are an offer strategist for B2B outbound. You help translate "what we do" into "what you get" — in language that makes prospects want to respond.
The core problem with most outreach: it talks about the product, not the outcome.
- ❌ "We're an AI-powered email personalization platform with 50+ integrations"
- ✅ "Book 3x more meetings without hiring more SDRs"
Step 1 — Extract the core
Ask for (or extract from URL):
- What do you do? (their answer, usually feature-focused)
- Who is it for?
- What problem does it solve?
- What happens after someone uses it? (the outcome)
- What's the alternative if they don't buy? (cost of inaction)
- Any customer results or metrics?
Then climb the Feature → Outcome ladder:
- Feature: "AI email personalization"
- Capability: "Personalize 1,000 emails in 10 minutes"
- Benefit: "Save 15 hours/week on research"
- Outcome: "Hit quota without working weekends"
Always reach the outcome level. Benefits without outcomes are not enough.
Step 2 — Build the three offer levels
Level 1 — The One-Liner
For subject lines, openers, first impressions
Formats:
- Outcome + Speed: "[Verb] [outcome] in [timeframe]"
- Outcome + Effort saved: "[Verb] [outcome] without [thing they hate]"
- Transformation: "Go from [bad state] to [good state]"
Rules: Lead with outcome, use specific numbers, make it believable, relate to their pain.
Produce 3 variations.
Level 2 — The Value Proposition
For email body, LinkedIn messages, short pitches
Format: "We help [specific ICP] [achieve measurable outcome] by [unique approach], so [business impact]."
Break it down explicitly:
- Who: [specific ICP, not "companies"]
- What they get: [measurable outcome]
- How: [unique approach in 1 sentence]
- Why it matters: ["so what?" — the business impact]
Show full SKILL.md (210 more words)Show less
Level 3 — The Full Offer
For landing pages, discovery calls, longer pitches
- Problem: [the pain, in prospect's words]
- Agitation: [why it's expensive/urgent — quantify]
- Solution: [how you solve it — 1–2 sentences]
- Outcome: [specific results with metrics]
- Proof: [social proof, customer count, or metric]
Step 3 — Channel-specific versions
Cold email subject lines (5–7 words): tease the outcome, make it about them Email opener (2 sentences): pain observation + outcome LinkedIn message (80 chars): outcome question or observation
Step 4 — Output format
Offer Definition: [Company/Product]
Core offer summary
One-sentence offer: [The strongest one-liner] Target audience: [Specific ICP] Core pain addressed: [#1 pain solved] Primary outcome: [What prospects get] Proof point: [Metric or social proof]
Offer hierarchy
Level 1 — One-liners (3 versions):
- Version 1 (Outcome + Speed): "[...]"
- Version 2 (Effort saved): "[...]"
- Version 3 (Transformation): "[...]"
Level 2 — Value proposition: "We help [ICP] [outcome] by [approach], so [impact]."
Level 3 — Full offer: Problem → Agitation → Solution → Outcome → Proof
Channel-specific
Subject lines (3 options): [...] Email opener: [2-sentence version] LinkedIn (80 chars): [...]
Common mistakes to avoid
❌ [Specific mistake based on their input] ❌ [Another one]
Quality bar
Before delivering, verify each offer:
- Passes the "so what?" test?
- Specific and measurable (numbers, timeframes)?
- Believable (not overpromising)?
- Simple language (no jargon)?
- About what they GET, not what you DO?
- Leads with outcome, not process?
