Requirements, PRDs, tickets and spec-driven development: turning intent into a spec an agent can build against. 12 tools list this as the main phase, and 7 more tools cover it. ## Main phase - [8090 Software Factory](https://aisdlclandscape.org/tools/8090.md) (8090): "The AI-native software development platform that keeps business leaders in the driver's seat, from spec to deploy." - [BMAD-METHOD](https://aisdlclandscape.org/tools/bmad.md) (BMad Code): "Breakthrough Method for Agile AI-Driven Development: open-source skills that bring planning and architecture into an agent's delivery workflow." - [ChatPRD](https://aisdlclandscape.org/tools/chatprd.md) (ChatPRD): "The AI product manager for your entire team: writes product docs, coaches PMs and hands specs to coding agents." - [Kiro](https://aisdlclandscape.org/tools/kiro.md) (Amazon Web Services): "Turn prompts into executable specs, validate code correctness and build across large codebases with parallel agents." - [Linear](https://aisdlclandscape.org/tools/linear.md) (Linear): "The system for product development, purpose-built for planning and building products with AI agents." - [OpenSpec](https://aisdlclandscape.org/tools/openspec.md) (Fission AI): "Spec-driven development for AI coding assistants, working with the 30+ tools a team already uses rather than one IDE." - [Rinkata Hub](https://aisdlclandscape.org/tools/rinkata.md) (Rinkata): "Where your team and your AI agents share one source of truth: goals, specs and decisions, so agents stay on track." - [Spec Kit](https://aisdlclandscape.org/tools/github-spec-kit.md) (GitHub): "Open-source toolkit for spec-driven development: commands that take an agent from intake through research and definition to tasks." - [SpecStory (RunStory)](https://aisdlclandscape.org/tools/specstory.md) (SpecStory): "Saves the conversations behind your code; its RunStory product tests software and sends defects back to the coding agent." - [Taskmaster AI](https://aisdlclandscape.org/tools/task-master.md) (Hamster): "Open-source, CLI-first tool that structures AI agent work: parse PRDs into tasks and subtasks with dependencies and acceptance criteria." - [Tessl](https://aisdlclandscape.org/tools/tessl.md) (Tessl): "Agent enablement platform: gives coding agents structured, versioned context, with a registry of skills and evals of model and agent harness combinations." - [Traycer](https://aisdlclandscape.org/tools/traycer.md) (Traycer AI): "Spec-first development for AI coding workflows: plan changes as epics, then hand them to the coding agent you already pay for." ## Also covers this phase - [Cline](https://aisdlclandscape.org/tools/cline.md) (Cline): "Open-source AI coding agent with Plan/Act modes, MCP integration and terminal-first workflows, using any model or endpoint." - [Devin](https://aisdlclandscape.org/tools/cognition-devin.md) (Cognition): "Devin, the first autonomous software engineer, plans, writes, tests and ships production code inside your existing workflows." - [G5](https://aisdlclandscape.org/tools/g5-labs.md) (G5 Labs): "The semantic abstraction layer for AI-native development: natural-language intent becomes the source code." - [GitHub Copilot](https://aisdlclandscape.org/tools/github-copilot.md) (GitHub (Microsoft)): "Your AI coding agent, every step of the way from an open issue to reviewing and merging a pull request, in the editor, terminal or github.com." - [GitLab Duo Agent Platform](https://aisdlclandscape.org/tools/gitlab-duo.md) (GitLab): "Custom AI workflow automation across the software lifecycle: specialised agents for planning, coding, security and deployment." - [IBM Bob (formerly watsonx Code Assistant)](https://aisdlclandscape.org/tools/ibm-wca.md) (IBM): "IBM Bob, an AI coding agent that accelerates delivery and application modernization across complex enterprise codebases." - [Rovo Dev](https://aisdlclandscape.org/tools/atlassian-rovo-dev.md) (Atlassian): "Atlassian's AI coding agent for software teams: plan, generate and review code from Jira, the CLI and Bitbucket; folding into Jira subscriptions."
