A team communication guide using the Johari Window, a model that maps what a person knows about themselves and what other people know about them. Its four areas help discuss shared knowledge, blind spots, private information, and unknown areas.

In plain words
What is it for?
Use it to explore leadership blind spots, give and receive feedback, build trust, and discuss communication problems within a team.
Why use it?
It helps teams uncover misunderstandings and feedback that people may not see about themselves. Making more concerns and expectations discussable can improve trust and communication.

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

johari-window 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 2d 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.

Johari Window

What do the people you work with most closely know about you that you do not know about yourself? The question is uncomfortable precisely because the answer, by definition, is invisible to the person it most concerns. Joseph Luft and Harrington Ingham -- whose first names combine to form "Johari" -- devised their four-pane window model in 1955 at the University of California, Los Angeles, as a tool for understanding self-awareness in group settings. Six decades later, it remains one of the most intuitively powerful frameworks for diagnosing trust, communication, and relational effectiveness in teams. Its enduring utility lies in a simple geometric truth: the less a team knows about each other's thinking, motivations, and concerns, the more organisational energy is wasted on misinterpretation, defensive posturing, and avoidable conflict.


The Framework

The Johari Window divides information about a person into four quadrants based on two axes: what is known to the self and what is known to others.

The Four Quadrants

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.
