What it does
Find Lookalikes is an agent skill from Othmane-Khadri/YALC-the-GTM-operating-system. Find companies similar to a seed domain via PredictLeads' similarcompanies endpoint and persist them as a result set ready for enrichment or qualification. Use when the user says 'find lookalikes for [domain]', 'companies similar to [name]', 'show me lookalike accounts', 'expand from this company', or 'discover similar prospects'. Side-effecting — calls PredictLeads API and writes to local cache.
Its SKILL.md is about 500 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/example-output.md`).
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
- The user says find lookalikes for [domain]
- Companies similar to [name]
- Show me lookalike accounts
- Expand from this company
Example prompts
- “find lookalikes for [domain]”
- “companies similar to [name]”
- “show me lookalike accounts”
- “/find-lookalikes”
Requirements
- Node.js
- A credential in PREDICTLEADS_API_KEY
Workflow steps
6 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
Shell commands in SKILL.md call:
npx
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use npx, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
PREDICTLEADS_API_KEY
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Find Lookalikes loads about 495 tokens when it runs, and up to ~682 if it reads all its reference files. Until then it costs about 104 tokens; SKILL.md has 178 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: notes
The automated check noted patterns worth knowing about, such as sudo or a known installer.
- NoteMentions a .env fileSKILL.md:36
cd ~/Desktop/gtm-os && set -a && source .env.local && set +a && \ - NoteMentions a .env fileSKILL.md:56
res `PREDICTLEADS_API_KEY` in `~/.gtm-os/.env`.
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.

Find Lookalikes
I'll wrap signals:similar. Ask for a seed domain, shell out to PredictLeads, dedupe + cache, and surface the lookalike list as a result set.
When This Skill Applies
- "find lookalikes for [domain]"
- "companies similar to [name]"
- "show me lookalike accounts"
- "expand from this company"
- "discover similar prospects"
NOT this skill (use prospect-discovery-pipeline instead):
- "find prospects like our best client" — that's the full 5-phase orchestrator (lookalikes → ICP filter → CMO finder → signals → variants).
NOT this skill (use enrich-with-signals instead):
- "enrich these companies with PredictLeads signals" — that pulls jobs/news/funding/tech for an EXISTING list.
Workflow
Step 0 — Ask for seed domain
"What's the seed domain or company URL?"
Step 1 — Validate (basic domain format)
Step 2 — Shell out
cd ~/Desktop/gtm-os && set -a && source .env.local && set +a && \
npx tsx src/cli/index.ts signals:similar --domain <domain>Single-command side-effecting → shell out per the benchmark.
Step 3 — Parse output
The CLI emits the lookalike list + result set id + cache hit/miss flags.
Step 4 — Render
See references/example-output.md.
Step 5 — Offer follow-ups
"Want me to (a) enrich these with signals via
enrich-with-signals, (b) qualify them viaqualify-leads?"
Notes
- Requires
PREDICTLEADS_API_KEYin~/.gtm-os/.env. - Cached 7 days per seed domain.
- ~1 PredictLeads credit per call.
