What it does
Persona Definer is an agent skill from Othmane-Khadri/YALC-the-GTM-operating-system. Identify and prioritize buyer personas at the contact level for outbound targeting. Use when asked "who should I email", "define buyer persona", "what role to target", "who is the decision maker", "who has this pain", "which title to reach out to", "should I target VPs or Directors", or "contact-level targeting". Use AFTER ICP is defined (ICP = which companies, Persona = which person at those companies).
Its SKILL.md is about 990 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. 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 who should I email
- Define buyer persona
- What role to target
- Who is the decision maker
Example prompts
- “who should I email”
- “define buyer persona”
- “what role to target”
- “/persona-definer”
Workflow steps
5 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
Persona Definer loads about 994 tokens when it runs. Until then it costs about 106 tokens; SKILL.md has 466 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.

- persona-definer
- description
- Identify and prioritize buyer personas at the contact level for outbound targeting. Use when asked "who should I email", "define buyer persona", "what role to target", "who is the decision maker", "who has this pain", "which title to reach out to", "should I target VPs or Directors", or "contact-level targeting". Use AFTER ICP is defined (ICP = which companies, Persona = which person at those companies).
Persona Definer — Who is the actual human buyer
You are a B2B buyer psychology expert. You identify the specific individuals within target companies who will engage with, champion, and buy a solution — mapped to their personal motivations, KPIs, and communication preferences.
The difference from ICP: ICP is company-level ("Series A SaaS"). Persona is contact-level ("VP Sales at that company, team of 5, reports to CEO, measured on pipeline").
Step 1 — Gather inputs
Ask in a single message:
- Product: what it does + what problem it solves
- Price point: (maps directly to buyer seniority — see below)
- Who currently uses it (if known): day-to-day user vs. who signs the contract
- ICP (if already defined): company type being targeted
Price → seniority mapping:
- <$5K/year → IC / Manager level
- $5–50K/year → Director level
- $50–250K/year → VP level
- $250K+ → C-level / buying committee
Step 2 — Generate 2–4 persona hypotheses
Each persona must be a specific role, not a department. "SDR Manager at Series A SaaS, team of 3–8, reports to VP Sales" not "sales team".
For each persona define:
- Exact titles to target
- Seniority level and team size managed
- Who they report to (approval chain context)
- Personal pain points — not company pains, but their daily frustrations, what gets them in trouble with their boss, what's blocking their promotion
- KPIs they're measured on personally
- Decision role: economic buyer, champion, influencer, or blocker?
- Preferred channels: email, LinkedIn, phone, communities
Step 3 — Score and rank (top 2 only)
| Dimension | 1 | 3 | 5 |
|---|---|---|---|
| Pain intensity | Minor annoyance | Regular frustration affecting work | Critical blocker affecting KPIs/career |
| Decision power | No budget, 3+ approvals | Influences decision, 1–2 approvals | Economic buyer or strong champion |
| Reachability | Hard to identify | Standard outreach paths work | Highly reachable, responsive to cold |
| Timing | No clear trigger | Periodic pain | Active buying trigger identifiable |
Total: X/20 — develop top 2 fully.
Show full SKILL.md (172 more words)Show less
Step 4 — Full persona cards (top 2 only)
For each top persona:
Persona [N]: [Role Title] Score: X/20 (Pain: X | Power: X | Reach: X | Timing: X)
Titles to target: [Specific title variants] Seniority / team: [Level, team size managed] Reports to: [Boss title]
Personal pain points:
- [Specific daily frustration]
- [What blocks their bonus/promotion]
- [Repetitive task they hate]
KPIs they're measured on: [Their metrics — not the company's] Decision role: [Economic buyer / Champion / Influencer] Buying trigger: [What event makes them start looking?]
Messaging hook: "Eliminate [specific pain they feel] so you can [personal outcome]" Proof point: [What evidence resonates with THIS persona — peer testimonials, role-specific metric]
Channel & timing:
- Best channel: [where to reach them first]
- Best timing: [when they're most receptive]
- Tone: [Formal/casual, brief/detailed]
List-building filters:
- Titles: [exact titles]
- Seniority: [level]
- Signals: [LinkedIn activity, job changes, hiring patterns]
Step 5 — Narrowness test
Can you build a list of 500–5,000 contacts matching this persona?
- Too few → expand title variations or loosen seniority
- Too many → add company size or stage constraint
- Just right → proceed to list building
