cold-outreach-skill
v1.0.0Meta-skill for orchestrating Apollo API, LinkedIn API, YC Cold Outreach, and MachFive Cold Email into a complete B2B cold outreach pipeline. Use when the user wants end-to-end lead sourcing, enrichment, personalized copy strategy, and generation-ready outreach sequences with strict quality and safet...
Installation
Purpose
Run a full B2B cold outreach workflow from ICP definition to sequence-ready output.
Primary objective: - Identify high-fit leads. - Enrich context for personalization. - Produce concise, non-salesy, high-response outreach sequences. - Return execution-ready assets for external sending/scheduling systems.
This is an orchestration skill. It coordinates upstream skills; it does not replace them.

Required Credentials
MATON_API_KEYforapollo-apiandlinkedin-api(Maton gateway)MACHFIVE_API_KEYforcold-email
Preflight checks:
echo "$MATON_API_KEY" | wc -c
echo "$MACHFIVE_API_KEY" | wc -c
If either key is missing or empty, stop before lead processing.
Job Context Template
Collect these inputs before execution:
offer: what is being sold (example: design service)icp_title: target role (example:CMO)icp_industry: target industry (example:SaaS)icp_location: target location (example:Berlin)lead_count_target(example:50)campaign_goal: reply, meeting, referral, audit request, etc.proof_points: case studies, metrics, social prooftone_constraints: plain-English, short, non-salesymachfive_campaign(campaign ID or campaign name to resolve)execution_mode:draft-onlyorgeneration-ready
Do not start writing copy until these are explicit.
Tool Responsibilities
Apollo API (apollo-api)
Use for lead discovery and basic enrichment.
Operationally relevant behavior from inspected skill:
- Search people: POST /apollo/v1/mixed_people/api_search
- Search filters include:
- q_person_title
- person_locations
- q_organization_name
- q_keywords
- Enrich person by email or LinkedIn URL:
- POST /apollo/v1/people/match
- Supports pagination via page and per_page.
- Uses Maton gateway and optional Maton-Connection header.
Primary output of this stage: - initial lead list with role/company/email/linkedin_url (when available)
LinkedIn API (linkedin-api)
Use for LinkedIn-side context where accessible through provided endpoints.
Operationally relevant behavior from inspected skill:
- Authenticated profile/user info endpoints (for connected account context).
- Content/posting APIs (ugcPosts) and organization post/stat APIs.
- Requires MATON_API_KEY and LinkedIn protocol headers.
Important boundary: - The inspected skill is not a generic scraper for arbitrary third-party personal profiles and recent personal posts. - If a workflow requires deep per-lead personal-post enrichment, mark that as additional-tool-required.
YC Cold Outreach (yc-cold-outreach)
Use as writing strategy/critique framework, not as a transport API.
Core principles to enforce: - single goal per email - human tone - deep personalization (not just token replacement) - brevity/mobile readability - credibility and proof - reader-centric language - clear CTA
MachFive Cold Email (cold-email)
Use for sequence generation from prepared lead records.
Operationally relevant behavior from inspected skill:
- Campaign required (campaign_id mandatory for generate endpoints).
- Single lead sync generation (/generate) can take minutes; use long timeout.
- Batch async generation (/generate-batch) returns list_id; poll list status; export when complete.
- Lead email is required.
- Supports structured sequence output with subject/body per step.
Canonical Workflow
Stage 1: Build lead universe (Apollo)
- Query Apollo for ICP-constrained leads (example: CMO + SaaS + Berlin).
- Page until
lead_count_targetor quality threshold is reached. - Normalize each lead record to required fields.
- Drop records without email if
generation-readymode is requested (MachFive requires email).
Recommended normalized lead schema:
{
"lead_id": "apollo-or-derived-id",
"name": "Anna Example",
"title": "Chief Marketing Officer",
"company": "Startup GmbH",
"location": "Berlin",
"email": "[email protected]",
"linkedin_url": "https://linkedin.com/in/...",
"source": "apollo-api"
}
Stage 2: Enrich personalization context
- Attempt LinkedIn/API enrichment within supported endpoints.
- If direct personal-post signal is unavailable, keep the context slot explicit as
not_available. - Optionally enrich from Apollo fields (company, role, keywords, domain context) to avoid fake personalization.
Personalization object per lead:
{
"icebreaker": "not_available_or_verified_fact",
"pain_hypothesis": "Likely CRO bottleneck in paid landing pages",
"proof_hook": "Helped X improve conversion by Y%",
"confidence": 0.0
}
Hard rule: - Never invent a post, interest, or quote.
Stage 3: Message strategy (YC framework)
For each lead, create a strategy brief before generating copy:
- Problem: what specific pain this role likely has
- Solution: what your offer solves
- Proof: one concrete metric/client signal
- CTA: one low-friction next step
Apply YC constraints: - one ask - short/mobile-first - human language - personalization grounded in verifiable context
Stage 4: Sequence generation (MachFive)
- Resolve campaign ID first (
GET /api/v1/campaigns) if not provided. - Submit leads with required email field.
- Prefer batch for many leads; poll until completion.
- Export JSON result and map sequences back to lead IDs.
Required generation payload hygiene:
- include name, title, company, email
- include linkedin_url and company_website when available
- set email_count intentionally (usually 3)
- use approved CTA set aligned with campaign goal
Stage 5: QA and decision gate
Before declaring output ready, validate each sequence:
- personalization factuality check
- YC rubric check (human, concise, one CTA)
- token insertion sanity (name/company/title correct)
- prohibited claims check (no fabricated proof)
Any failed sequence must be flagged needs_revision.
Stage 6: Scheduling and send handoff
This meta-skill outputs send-ready recommendations, not direct send automation.
If user asks for timing optimization (for example Tuesday 10:00), return it as a scheduling recommendation field and handoff plan.
Example handoff object:
{
"lead_id": "...",
"sequence_status": "approved",
"suggested_send_time_local": "Tuesday 10:00",
"timezone": "Europe/Berlin",
"send_system": "external",
"notes": "Timing is recommendation-only; execution tool must schedule/send."
}
Causal Chain (Scenario Mapping)
For the scenario "sell design services to startup marketing leaders":
- Apollo returns target leads (example target: 50 CMOs in Berlin SaaS).
- LinkedIn/API enrichment attempts to add usable context per lead.
- YC framework converts lead context into a concise Problem → Solution → Proof → CTA angle.
- MachFive generates multi-step sequences with validated variables.
- Agent outputs:
- approved sequences
- quality score per lead
- scheduling recommendation (example: Tuesday 10:00 local)
Output Contract
Always return these sections:
LeadSummary- requested vs qualified lead count
-
rejection reasons (missing email, poor fit, duplicate)
-
EnrichmentSummary - fields successfully enriched
-
unavailable fields and why
-
SequencePackage - one object per lead with subjects/bodies by step
-
QA status (
approvedorneeds_revision) -
ExecutionPlan - send-time recommendation
- required external sender/scheduler
- blockers (missing campaign, missing API key, missing email)
Guardrails
- Never fabricate personalization facts.
- Never claim a lead posted something unless sourced and verifiable.
- Do not proceed to MachFive generation without campaign ID resolution.
- Do not mark sequence
approvedwhen CTA is unclear or multiple asks exist. - Keep language non-manipulative and compliant with outreach policies.
Failure Handling
- Missing
MATON_API_KEY: stop Apollo/LinkedIn stages. - Missing
MACHFIVE_API_KEY: stop generation stage and return draft-only strategy. - Missing campaign ID: list campaigns and request explicit selection.
- Batch timeout/partial output: continue via list status + export recovery flow.
- Insufficient lead quality: return reduced high-quality set instead of forcing volume.
Known Limits from Inspected Upstream Skills
linkedin-apiinspected capability set is not equivalent to unrestricted scraping of arbitrary personal lead activity.cold-emailgenerates sequences but does not itself guarantee outbound send scheduling/execution.apollo-apiprovides search/enrichment primitives; email deliverability validation beyond provider fields may require extra tooling.
Treat these as explicit constraints in planning and reporting.
