tsna

tsna is a skill for Claude Code, Codex from LeoLin990405/r-analytics-skill. It costs 23 tokens per session (521 once invoked), scanned A, original, MIT.

An R toolkit for analysing temporal networks, where connections can appear, disappear, or change over time.

In plain words
What is it for?
Use it to calculate time-aware paths, reachability, degree, edge duration, vertex activity, and network statistics over intervals.
Why use it?
It helps answer questions about who could reach whom during a time period, rather than treating every connection as permanent.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

tsna 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 9d 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.

What it actually says

tsna

Tools for temporal social network analysis.

Temporal Paths

library(tsna)

# Forward reachable set
tPath(dnet, v = 1, direction = "fwd",
  start = 0, end = 10)

# Backward reachable set
tPath(dnet, v = 1, direction = "bkwd",
  start = 0, end = 10)

# Geodesic distance
tPath(dnet, v = 1, type = "geodesic")

Reachability

# Forward reachability
reach_fwd <- tReach(dnet, direction = "fwd")

# Backward reachability
reach_bkwd <- tReach(dnet, direction = "bkwd")

# Reachability matrix
tReach(dnet, graph = TRUE)

Temporal Metrics

# Temporal degree
tDegree(dnet)

# At specific time
tDegree(dnet, at = 5)

# Over interval
tDegree(dnet, start = 0, end = 10)

SNA Statistics Over Time

# Apply SNA function over time
tSnaStats(dnet, snafun = "betweenness")
tSnaStats(dnet, snafun = "closeness")
tSnaStats(dnet, snafun = "degree")

# Custom function
tSnaStats(dnet, snafun = function(x) {
  mean(degree(x))
})

Edge Duration

# Edge durations
edgeDuration(dnet)

# Mean duration
mean(edgeDuration(dnet))

Vertex Activity

# Vertex activity duration
vertexDuration(dnet)

Transmission Trees

# Infection/transmission tree
tree <- tPath(dnet, v = 1, direction = "fwd",
  type = "earliest.arrive")

# Plot tree
plot(tree)

Temporal Correlation

# Correlation between time slices
tCorrelate(dnet, lag = 1)

Aggregation

# Aggregate over time windows
tErgmStats(dnet,
  formula = ~ edges + mutual,
  start = 0, end = 10,
  time.interval = 1)

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.

tsna is a skill published in the GitHub repository LeoLin990405/r-analytics-skill (5 stars, last pushed 6mo ago), licensed MIT. It adds 23 tokens to every session and 521 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
