One initiative through every stage
Requirements, plans, agent runs, reviews, decisions, and pull requests stay with the same initiative
Product sets the direction. Engineers keep the agents they trust. One Horizon carries the same initiative through delivery.

Requirements, plans, agent runs, reviews, decisions, and pull requests stay with the same initiative
Product, engineering, design, and reviewers work from the same brief in the tools that fit their role
See what is moving, blocked, waiting for review, or complete across the product team
Start with the product outcome and keep every plan, handoff, review, and decision attached until release.
Writer Mode and linked documents turn rough requirements into initiatives the team can plan, assign, and review.

Move each stage between product, engineering, security, Codex, Claude Code, Cursor, or a custom agent.

Comments, replies, mentions, documents, and decisions remain available to everyone who joins later.

Review each change beside the original requirement, plan, comments, and code before approval.

Give every contributor the context and ownership they need without forcing one tool or one rigid process.
Follow one initiative through requirements, planning, implementation, review, and pull request
Keep the coding agents and developer tools your engineers already use
Keep research, implementation notes, reviews, and decisions ready for the next change
