psychology-agent: Settings file for Claude Code

.claude/settings.json

psychology-agent is a settings file for Claude Code from safety-quotient-lab/psychology-agent. Its token cost is not measured, scanned A, original, Apache-2.0.

A collection of automatic checks that run around file access, shell commands, edits, agent work, and external actions.

In plain words
What is it for?
It is for checking project boundaries, screening credentials, detecting working modes, reviewing external GitHub actions, and controlling when tools or subagents start.
Why use it?
It helps catch unsafe or unsuitable actions before they happen, including credential exposure, context pressure, and actions outside the intended project area.

Settings file for Claude Code

Written for Claude Code: PreToolUse hook event. Also seen: reads .claude/ paths; mentions subagents.

This is safety-quotient-lab/psychology-agent's own configuration. It tells Claude Code how to work on psychology-agent itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything psychology-agent configures →

One of 15 entries in settings.json upstream. Installing this one merges just its entry into your config; the other 14 are separate, each on its own page.

Security

Grade A, and why

psychology-agent 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 8d 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 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.
