Chivalry (骑士精神)

An open-source Chivalry skill pack built primarily for Claude Code, with ready-to-use adapters for Cursor and Codex.

This is not fake gallantry, macho cosplay, or “be nice at all costs.” It is a practical honor engine.

What it does

The skill looks at a message, decision, or situation and answers two questions:

1. Is this knightly, passable, unknightly, base, or craven?
2. What is the more honorable move right now?

It is designed for modern situations: conflict, apology, leadership, loyalty, romance, bystander moments, public speech, retaliation, status games, and damaged trust.

Why this idea is fun

A weak “virtue” skill becomes a preachy etiquette bot. A good chivalry skill has tension.

The interesting part is not politeness. The interesting part is conflict between values:

• loyalty vs justice
• courage vs prudence
• mercy vs accountability
• courtesy vs blunt truth
• devotion vs consent
• service vs self-respect

That gives the skill actual bite.

The core code

This skill judges by seven tests:

• Oath — Did you keep your word, duty, or implied obligation?
• Courage — Did you face the rightful burden instead of hiding?
• Mercy — Did you avoid needless cruelty or humiliation?
• Courtesy — Did you preserve dignity, especially in public?
• Protection — Did you shield the more exposed person?
• Honor — Did you act fairly, openly, and without cheap tricks?
• Measure — Did you show restraint, or did ego take the wheel?

What it rejects

The skill is deliberately hostile to fake chivalry:

• possessiveness disguised as protection
• jealousy disguised as devotion
• fighting for ego and calling it courage
• white-knighting for applause
• public humiliation as “honest truth”
• grand gestures that create debt
• sexism, paternalism, stalking, coercion, revenge theater

Consent, law, safety, and basic dignity outrank pageantry.

Install

Option 1: use it as a standalone skill

Copy this directory:

plugins/chivalry/skills/chivalry/

to:

~/.claude/skills/chivalry/

Then use:

/chivalry Your scenario here

This is the nicest developer experience because the command is short.

Option 2: test the plugin locally

Run Claude Code with the plugin directory:

claude --plugin-dir ./plugins/chivalry

Then use:

/chivalry:chivalry Your scenario here

Option 3: publish the marketplace

Once this repo is on GitHub or another git host:

claude plugin marketplace add <your-repo>
claude plugin install chivalry@chivalry-tools

Then invoke the skill:

/chivalry:chivalry I publicly embarrassed a teammate while proving a point. Was that knightly?

Option 4: use it in Cursor

Copy this file into your target project's .cursor/rules/ directory:

.cursor/rules/chivalry.mdc

Then ask normally in Cursor chat, for example:

Is this knightly, or am I dressing up vanity as virtue?

Option 5: use it in Codex

Copy AGENTS.md to the root of your target repo, or merge its Chivalry section into an existing AGENTS.md.

Then ask normally in Codex, for example:

Give me the Chivalry read on this apology draft.

Example prompts

• “I promised I would help, but now I want out. What is the knightly move?”
• “My boss wants me to cover up a mistake. Is loyalty more important here?”
• “I called someone out in public because they deserved it. Was that honorable?”
• “Someone weaker was being mocked and I stayed quiet. What would a knight have done?”
• “Is ghosting after three dates unchivalrous?”
• “I want to protect my girlfriend by checking who she talks to. Is that chivalry or control?”
• “这算不算骑士精神？”
• “一个体面的骑士在这种局面下该怎么做？”
