+
+## What needs to change?
+
+A clear description. Be specific about which file, section, or
+keyword you're referring to.
+
+Examples:
+- The "Why" section in the README doesn't mention `claude code undo`
+- The `codex checkpoint` H2 is buried under a different name
+- The `npm codex undo` SERP shows our package but the description is
+  not compelling
+- Add a comparison table with `pi-rollback`
+- Add a backlink to the Codex `app-server` docs
+
+## Why?
+
+What's the user pain? (e.g., "I can't find the tool when I search
+`codex undo`")
+
+## Proposed change
+
+Concrete text or code, if you have it.

+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+We as members, contributors, and leaders pledge to make participation in our
+community a harassment-free experience for everyone, regardless of age, body
+size, visible or invisible disability, ethnicity, sex characteristics, gender
+identity and expression, level of experience, education, socio-economic
+status, nationality, personal appearance, race, caste, color, religion, or
+sexual identity and orientation.
+
+We pledge to act and interact in ways that contribute to an open, welcoming,
+diverse, inclusive, and healthy community.
+
+## Our Standards
+
+Examples of behavior that contributes to a positive environment for our
+community include:
+
+- Demonstrating empathy and kindness toward other people
+- Being respectful of differing opinions, viewpoints, and experiences
+- Giving and gracefully accepting constructive feedback
+- Accepting responsibility and apologizing to those affected by our mistakes,
+  and learning from the experience
+- Focusing on what is best not just for us as individuals, but for the
+  overall community
+
+Examples of unacceptable behavior include:
+
+- The use of sexualized language or imagery, and sexual attention or
+  advances of any kind
+- Trolling, insulting or derogatory comments, and personal or political attacks
+- Public or private harassment
+- Publishing others' private information, such as a physical or email
+  address, without their explicit permission
+- Other conduct that could reasonably be considered inappropriate in a
+  professional setting
+
+## Enforcement Responsibilities
+
+Community leaders are responsible for clarifying and enforcing our standards
+of acceptable behavior and will take appropriate and fair corrective action
+in response to any behavior that they deem inappropriate, threatening,
+offensive, or harmful.
+
+Community leaders have the right and responsibility to remove, edit, or
+reject comments, commits, code, wiki edits, issues, and other contributions
+that are not aligned to this Code of Conduct, and will communicate reasons
+for moderation decisions when appropriate.
+
+## Scope
+
+This Code of Conduct applies within all community spaces, and also applies
+when an individual is officially representing the community in public
+spaces. Examples of representing our community include using an official
+e-mail address, posting via an official social media account, or acting as
+an appointed representative at an online or offline event.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported to the community leaders responsible for enforcement at
+[opening an issue](https://github.com/Nainish-Rai/agent-rollback/issues/new).
+All complaints will be reviewed and investigated promptly and fairly.
+
+All community leaders are obligated to respect the privacy and security of
+the reporter of any incident.
