description: Weighted social-graph ranking for warm intro discovery, bridge scoring, and network gap analysis across X and LinkedIn. Use when the user wants the reusable graph-ranking engine itself, not the broader outreach or network-maintenance workflow layered on top of it.

Social Graph Ranker

Canonical weighted graph-ranking layer for network-aware outreach.

Use this when the user needs to:

• rank existing mutuals or connections by intro value
• map warm paths to a target list
• measure bridge value across first- and second-order connections
• decide which targets deserve warm intros versus direct cold outreach
• understand the graph math independently from lead-intelligence or connections-optimizer

When To Use This Standalone

Choose this skill when the user primarily wants the ranking engine:

• "who in my network is best positioned to introduce me?"
• "rank my mutuals by who can get me to these people"
• "map my graph against this ICP"
• "show me the bridge math"

Do not use this by itself when the user really wants:

• full lead generation and outbound sequencing -> use lead-intelligence
• pruning, rebalancing, and growing the network -> use connections-optimizer

Inputs

Collect or infer:

• target people, companies, or ICP definition
• the user's current graph on X, LinkedIn, or both
• weighting priorities such as role, industry, geography, and responsiveness
• traversal depth and decay tolerance

Core Model

Given:

• T = weighted target set
• M = your current mutuals / direct connections
• d(m, t) = shortest hop distance from mutual m to target t
• w(t) = target weight from signal scoring

Base bridge score:

B(m) = Σ_{t ∈ T} w(t) · λ^(d(m,t) - 1)

Where:

• λ is the decay factor, usually 0.5
• a direct path contributes full value
• each extra hop halves the contribution

Second-order expansion:

B_ext(m) = B(m) + α · Σ_{m' ∈ N(m) \\ M} Σ_{t ∈ T} w(t) · λ^(d(m',t))

Where:

• N(m) \\ M is the set of people the mutual knows that you do not
• α discounts second-order reach, usually 0.3

Response-adjusted final ranking:

R(m) = B_ext(m) · (1 + β · engagement(m))

Where:

• engagement(m) is normalized responsiveness or relationship strength
• β is the engagement bonus, usually 0.2

Interpretation:

• Tier 1: high R(m) and direct bridge paths -> warm intro asks
• Tier 2: medium R(m) and one-hop bridge paths -> conditional intro asks
• Tier 3: low R(m) or no viable bridge -> direct outreach or follow-gap fill

Scoring Signals

Weight targets before graph traversal with whatever matters for the current priority set:

• role or title alignment
• company or industry fit
• current activity and recency
• geographic relevance
• influence or reach
• likelihood of response

Weight mutuals after traversal with:

• number of weighted paths into the target set
• directness of those paths
• responsiveness or prior interaction history
• contextual fit for making the intro

Workflow

1. Build the weighted target set.
2. Pull the user's graph from X, LinkedIn, or both.
3. Compute direct bridge scores.
4. Expand second-order candidates for the highest-value mutuals.
5. Rank by R(m).
6. Return:

• best warm intro asks
• conditional bridge paths
• graph gaps where no warm path exists
