Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00223 | $0.01694 |
| Opus 5 | $0.00112 | $0.00847 |
| Sonnet 5 | $0.00045 | $0.00339 |
| Haiku 4.5 | $0.00022 | $0.00169 |
Grade A, and why
signal-sourcer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 111 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Setup (Run Once Per Session)
Before loading any sub-skill or resource, locate this skill's install directory:
- Use Glob to search for
**/signal-sourcer/SKILL.md - The directory containing this SKILL.md is
SKILL_BASE - Sub-skills are at:
{SKILL_BASE}/.claude/skills/{sub-skill}/SKILL.md - Resources are at:
{SKILL_BASE}/resources/...
Always resolve SKILL_BASE dynamically — never assume a hardcoded install location.
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

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
