CoreStory + Cursor Agentic Bug Resolution Playbook

Let CoreStory + Cursor Resolve Your Bugs For You

Resolve defects quickly with a disciplined, test-first flow inside your IDE. This playbook pairs CoreStory’s code intelligence with Claude Code (via MCP + Skill/Command files) so Claude understands intended behavior, navigates precisely to relevant code, writes a failing test, applies the minimal fix, and validates the result—end to end.

What you’ll get

• A six-phase, agentic bug workflow wired into Claude Code (Intake → Oracle → Navigator → TDD Investigation → Fix & Verify → Capture).
• Drop-in Skill and Command files that activate consistent bug-resolution behavior across repos.
• Prompt patterns, checkpoints, and quality gates that enforce invariants and regression safety on every fix.

Why this matters

CoreStory acts as your oracle (desired behavior, invariants, interfaces) and navigator (file:line guidance, logic paths). Claude uses that context to hypothesize root causes, reproduce with tests, and implement the smallest safe change—cutting time to root cause and reducing regressions by validating against both spec and implementation.

How it works (in practice)

1. Bug intake & context — Pull the ticket and open a CoreStory conversation for the project.
2. Oracle phase — Query CoreStory for architecture, invariants, acceptance criteria, and history.
3. Navigator phase — Map symptoms → code paths; get precise files/methods to inspect.
4. TDD investigation — Write a failing test to reproduce and encode the invariant.
5. Solution development — Apply the minimal fix; expand edge-case tests; validate with CoreStory.
6. Completion & capture — Commit with rich context and update the ticket with evidence.

Fast start (5 minutes)

• Install CoreStory MCP in Claude Code and verify with “List my CoreStory projects.”
• Add the provided Skill and /fix-bug Command files to your repo.
• Start with: /fix-bug "<ticket or summary>" — follow the six phases and pause after each step.

Who it’s for

• Teams that want repeatable, high-signal triage for production bugs.
• ICs practicing TDD/characterization in unfamiliar areas of large codebases.
• Platform/QA leaders standardizing quality gates and traceability.

What’s inside the playbook

• Prereqs & Setup for CoreStory MCP in Claude Code.
• Skill & Command files (markdown) to automate the workflow.
• Prompting patterns library for discovery, hypothesis, validation, and edge-case expansion.
• Advanced patterns: security, performance, integration impact, dependency/version issues.
• Metrics & KPIs: time to root cause, investigation accuracy, regression rate, autonomy.

Results to expect

• 50–70% faster time to root cause, higher first-hypothesis accuracy (70–90%), and <5% regression rate when fixes are grounded in CoreStory context and validated via TDD. Expect cleaner commit history, better traceability, and reusable conversations that speed future investigations.
