psyche

psyche is an agent for Claude Code from vibeeval/vibecosystem. It costs 34 tokens per session (3,922 once invoked), scanned A, original, MIT.

A developer-psychology agent focused on mental clarity, decision quality, frustration, and resilience during coding sessions. It uses approaches such as rubber-duck debugging, where explaining a problem aloud helps uncover the answer.

In plain words
What is it for?
Use it to reflect on a coding session, clarify motivation, question assumptions, spot unhelpful thought patterns, manage frustration, and mediate disagreements between agents.
Why use it?
It helps when frustration, unclear goals, repeated mistakes, or too many decisions make coding harder. It encourages reflection and questions that help the developer reason through the problem.

Agent for Claude Code

Written for Claude Code: a Claude Code subagent (agents/*.md). Also seen: model in frontmatter; reads .claude/ paths.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is cd ~/.claude && PYTHONPATH=scripts python3 scripts/core/recall_learnings.py --query "<session psychology keywords>" --k 3 --text-only.

Good fit Use it to reflect on a coding session, clarify motivation, question assumptions, spot unhelpful thought patterns, manage frustration, and mediate disagreements between agents.

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

psyche 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 5d 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.
