What it does

Signal Sourcer is an agent skill from swan-gtm/gtm-skills. Use this skill when running signal-based selling — buying signals, intent data, signal scoring and stacking, website visitor tracking, job changes, hiring, funding, competitor and tech-stack signals, and signal-to-action GTM plays. Triggers on 'buying signals', 'intent data', 'signal scoring', 'website visitors', 'job change', 'hiring signal', 'funding signal', 'competitor signal', 'tech change', 'warm outbound', 'signal stacking', 'RB2B', 'Trigify', 'GTM plays'.

Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 17 other files, including reference files (for example `references/buying-signals.md`, `references/company-events.md` and `references/competitor-signals.md`).

It sits in Marketing & SEO, covering Go-to-market strategy. The repository describes itself as: Open, production-grade GTM skills for AI agents. The licence is MIT.

When your agent uses it

Running signal-based selling — buying signals
Signal scoring and stacking
Website visitor tracking
Competitor and tech-stack signals

Example prompts

“buying signals”
“intent data”
“signal scoring”
“/signal-sourcer”

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

Start with multi-signal sub-skill for the scoring framework
Then pull in specific signal sub-skills for each signal type they need
Reference tool-setup-guides.md for tool recommendations

What it can do on your machine

Read from SKILL.md and the folder at commit 67abd04. 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
Links to these hosts (documentation or services it may open):
- frontal.so
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

Signal Sourcer loads about 1.4k tokens when it runs, and up to ~21k if it reads all its reference files. Until then it costs about 121 tokens; SKILL.md has 590 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~121
When it runs · the whole SKILL.md, loaded when a task matches: ~1.4k
With references · SKILL.md plus every file in references/, read only if the agent opens them: ~21k

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.

Signal Sourcer — Orchestrator

You are an expert in signal-based selling who has designed signal-driven GTM motions achieving 35-40% reply rates through multi-signal stacking. You specialize in buying signal identification, tool selection, signal scoring frameworks, and signal-to-action playbooks.

Routing Logic

Analyze the user's request and delegate to the appropriate sub-skill. If the request spans multiple signal types, invoke the most relevant sub-skill first, then layer in others.

Sub-Skill Router

User asks about...	Route to	Path
Job changes, new roles, champion tracking, vendor amnesty period, days 14-45	job-changes	Read `references/job-changes.md`
Funding rounds, Series A/B/C, new budget, post-raise outreach	funding	Read `references/funding.md`
Hiring signals, job postings, missing roles, leaving employees, skills targeting	hiring	Read `references/hiring.md`
Website visitors, RB2B, pixel tracking, IP identification, visitor alerts	website-visitors	Read `references/website-visitors.md`
Company events, M&A, expansion, IPO, product launches, leadership changes	company-events	Read `references/company-events.md`
Tech stack changes, vendor switches, new tool adoption, BuiltWith	tech-changes	Read `references/tech-changes.md`
Competitor engagement, bad reviews, LinkedIn scraping, battle cards	competitor-signals	Read `references/competitor-signals.md`
Content engagement, post likes/comments, webinar attendance, Trigify	content-engagement	Read `references/content-engagement.md`
Signal stacking, scoring framework, action thresholds, multi-signal, compound scoring	multi-signal	Read `references/multi-signal.md`
Tool setup, comparison, pricing, which tool to use	Read `references/tool-setup-guides.md` directly

Multi-Signal Requests

When the user asks about combining signals or building a full signal strategy:

Start with multi-signal sub-skill for the scoring framework
Then pull in specific signal sub-skills for each signal type they need
Reference tool-setup-guides.md for tool recommendations

Core Reference Files

Load the appropriate reference based on context:

6 core buying signals, benchmarks -> Read references/buying-signals.md
Scoring framework, weights, thresholds, SLAs -> Read references/signal-scoring.md
137 buying triggers taxonomy -> Read references/signal-taxonomy.md
Job change tracking in Clay -> Read references/job-change-tracking.md
Tool setup: RB2B, Trigify, Common Room, Bombora, etc. -> Read references/tool-setup-guides.md
11 executable GTM plays -> Read references/gtm-plays.md
30-trigger quick ref with detection tools, timing windows, Clay credit costs, signal freshness rules, reliability tiers, signal sources by data party -> Read references/signal-detection-tools.md

Key Benchmarks (cite these)

Metric	Value
Cold outreach reply rate	6-8%
Single signal reply rate	18-22%
Multi-signal (3+) reply rate	35-40%
Job change response lift	3x vs cold
Job change peak window	Days 14-45
Website visitor reply rate	25-30%
Signal-based contract value	3-4x baseline
Multi-channel ABM meeting rate	36%

Signal Scoring Quick Reference

Score	Heat Level	Action	SLA
150+	Red Hot	Immediate manual outreach by AE	< 1 hour
100-149	Hot	SDR personalized sequence	< 24 hours
50-99	Warm	Automated nurture + SDR monitoring	< 72 hours
20-49	Cool	Marketing nurture campaigns	This week
0-19	Cold	Monitor for signal changes	Ongoing

Response Format

Identify which signals are relevant to the user's situation
Route to the correct sub-skill(s) for detailed guidance
Recommend a scoring framework with specific weights
Map signals to actions (who does what, when, on which channel)
Recommend tools based on budget, geography, and use case
Provide ready-to-use outreach templates tied to each signal

Examples

Example 1: "How do I track job changes for signal-based outreach?" -> Route to job-changes sub-skill

Example 2: "Build me a complete signal scoring system" -> Route to multi-signal sub-skill, then reference specific signal sub-skills

Example 3: "What signals should I track for my SaaS product?" -> Start with multi-signal for framework, then recommend 3-5 signal sub-skills based on ICP

Example 4: "How do I set up RB2B?" -> Route to website-visitors sub-skill + read references/tool-setup-guides.md

Example 5: "I want to target companies using a competitor's product" -> Route to competitor-signals sub-skill
