CoreStory is now available as a source of codebase intelligence for teams building with Factory via MCP. By combining Factory’s agentic development platform with CoreStory’s deep codebase intelligence, teams can equip Droids with the architectural context, dependency insights, and behavioral understanding to produce high-quality code changes with confidence.

What This Unlocks

When CoreStory is used in Droid workflows, teams see improvements across common engineering tasks:

• Faster onboarding to new or complex codebases
• More accurate bug investigation and resolution** informed by dependency, invariant, and historical behavior analysis**
• Feature implementations that follow existing patterns** and fit within architectural constraints**
• Reliable, pattern-aligned test generation
• Safer changes through dependency impact analysis
• Automatic discovery of APIs and integration points
• Code that aligns with established standards and conventions

CoreStory provides the broader codebase context that guides Droids toward informed, targeted modifications, resulting in more targeted changes.

More Predictable Agent Performance

For engineering teams, the value of this Factory and CoreStory shows up in the day-to-day flow of work. With CoreStory providing system-level understanding and Factory orchestrating agent execution, agent-native development becomes more predictable at every stage.

In recent evaluations, Droid with CoreStory resolved 40 of the 45 hardest tasks in the swe-bench-verified dataset – a higher resolution rate than the other evaluated agent configurations. This result improves on Droid’s baseline results and represents a new standard for agentic performance, particularly on complex and long-running tasks.

When working with CoreStory, bug fixes are driven by real context instead of trial and error. Feature development begins with clarity on how changes fit into the existing architecture. Tests reflect real patterns rather than generic templates. Each change is validated with a grounded view of dependencies and behavior.

The result is an SDLC where agents accelerate delivery even further — making agent-native workflows a dependable part of how teams ship software.

Getting Started

Teams can start using CoreStory with Factory today via MCP. Adding CoreStory’s codebase intelligence to Droid workflows brings clearer context, stronger pattern adherence, and more predictable agent behavior.

To explore how the two platforms can fit into your development process, reach out to your Factory or CoreStory representative.

For teams looking for a practical starting point, CoreStory’s Agentic Bug Resolution Playbook provides a guided example of how this setup can be applied in practice.

About Factory

Factory is pioneering agent-native development, a new way of building software that keeps developers in control of the important high-level details while agents – or Droids – handle the coding. By shifting from autocomplete to delegation, Factory puts the orchestration and management of Droids into the hands of engineers and enables teams to ship faster, improve code quality, and embrace a new philosophy of working with AI. Founded in 2023 and headquartered in San Francisco, Factory is backed by investors including Sequoia Capital, NEA, NVIDIA, J.P. Morgan, Abstract Ventures, Mantis VC, SV Angel and BoxGroup.
