psychosynth is a skill for Claude Code, Codex from 3esign/psychosynth. It costs 162 tokens per session (4,020 once invoked), scanned A, original, no licence file.

A source of synthetic behavioral data for simulating agents with personality profiles, decision-making patterns, and cognitive biases.

In plain words
What is it for?
Use it for agent simulations involving trading or negotiation, Big Five or Dark Triad profiles, prospect theory, and cognitive-bias references.
Why use it?
It lets you test simulated responses in high-stakes situations without treating token usage data as human behavior data.

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

psychosynth scanned grade A with 1 finding 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 6d ago.

The scan reads SKILL.md. This mod also ships 8 executable files (psychosynth.mjs, scripts/discovery.sh, scripts/preview.sh, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

The source is not reproduced here

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

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.
