CoreStory + Cursor Agentic Bug Resolution Playbook

Let CoreStory + Cursor Fix Your Bugs For You

Turn bug fixing into a guided, test-first workflow that runs entirely inside Cursor. This playbook pairs CoreStory’s code intelligence with Cursor’s project rules so investigations follow a consistent six-phase process—write a failing test first, apply the smallest safe fix, and validate against real system intent.

What you’ll get

• A ready-to-use .cursorrules .mdc file that auto-activates a six-phase bug workflow whenever you ask Cursor to fix an issue.
• Prompts, checkpoints, and artifacts (tests, diffs, commit message template, ticket update) baked into the flow.
• Guidance for ticket integrations (GitHub/Jira/Linear/Azure DevOps) and CI hooks to enforce tests for every fix.

Why this matters

CoreStory exposes intended behavior, invariants, and integration points; Cursor applies always-on rules so every fix is repeatable and auditable. The result is faster root-cause discovery, higher first-hypothesis accuracy, and fewer regressions—because fixes are validated against both spec and implementation.

How it works

1. Bug intake & context — Pull the ticket or parse your description; open a CoreStory investigation thread.
2. Oracle phase — Query CoreStory for architecture, invariants, data structures, and recent changes.
3. Navigator phase — Map symptoms to code paths; identify precise file and targets and form hypotheses.
4. Test-first investigation — Write a failing test that encodes the invariant; confirm failure; locate the defect.
5. Solution development — Apply the minimal change; add edge-case tests; run full suite; validate with CoreStory.
6. Completion & capture — Generate a structured commit message, update the ticket, and preserve the transcript.

Fast start (5 minutes)

• Add the provided .cursorrules file into the repo root and commit it.
• Open Cursor and ask: “Fix bug <ID> using the CoreStory workflow—pause after each phase.”
• Iterate in-editor: generate → run → validate → refine → commit.

Who it’s for

• Teams standardizing triage and fix quality across services.
• ICs working in unfamiliar areas (characterization + TDD).
• Platform/QA leaders enforcing invariants and regression gates in CI.

What’s inside the playbook

• Project Rule file (.cursorrules) with the six-phase workflow.
• Prompts & checkpoints for chat, inline chat, and code actions.
• Configuration options (global vs project rules, verbosity, domain invariants).
• Metrics & success indicators and example CI checks for “tests accompany fixes.”
• Example session from request → failing test → fix → commit → ticket update.

Results to expect

• Time to root cause: target 15 minutes (vs. hours).
• First-hypothesis accuracy: 70–90% with CoreStory guidance.
• Fix quality: <5% regression rate and 100% tests on bug paths, with clear commit and ticket traceability.
