Software Engineering Toolkit is an adapted multi-skill engineering toolkit inspired by Matt Pocock's open-source skills repository. It helps agents and developers align on intent, model the domain, write specs and tickets, design deep modules, use test-driven development, diagnose bugs, review code, research with citations, create handoffs, and improve codebase architecture.
Install

Open Plugins in the ChatGPT sidebar (web or desktop), search for “Software Engineering Toolkit” and select +. You'll be asked to sign in to any connected service on first use. Then type @ in a chat to call it.
Skills 15
- code-review
Review changes against both engineering standards and the originating specification.
- codebase-design
Design deep modules with small interfaces, clear seams, and testable responsibilities.
- diagnosing-bugs
Diagnose bugs and regressions through reproduction, minimization, instrumentation, fixing, and regression testing.
- domain-modeling
Build a shared vocabulary and test it against real scenarios before changing code.
- grilling
Interview the user until a plan, design, or decision is specific enough to execute.
- handoff-and-context
Create compact handoffs and shared project context so another agent can continue accurately.
- implementation
Implement specs or tickets in small slices with tests, review, and a clear completion report.
- merge-conflicts
Resolve merge or rebase conflicts by tracing intent and preserving both sides where appropriate.
- prototyping
Build small throwaway prototypes to answer uncertain design, interaction, or technical questions.
- research
Investigate engineering questions with high-trust primary sources and cited findings.
- software-engineering-toolkit
Route engineering work into disciplined alignment, design, testing, diagnosis, review, research, and delivery workflows.
- tdd
Drive implementation with a red-green-refactor loop and meaningful behavior tests.
- to-spec
Turn a conversation or request into a precise, testable engineering specification.
- to-tickets
Break a plan into small tracer-bullet tickets with dependencies and completion criteria.
- writing-for-agents
Write concise, discoverable instructions and project documents that agents can follow reliably.
Things to ask
- “Grill me until this engineering plan is unambiguous.”
- “Turn this request into a testable implementation spec.”
- “Diagnose this bug with a disciplined feedback loop.”
Disconnect or uninstall
- 1In ChatGPT
Disconnect an account in Settings → Apps or Plugins. To remove the plugin itself, open Software Engineering Toolkit in the Plugin Directory and select Uninstall plugin. Uninstalling can disconnect every account connected through it, and plugins your workspace installs may not offer the option.
- 2In Codex
Run /plugins in the Codex CLI, select the plugin and uninstall it, or press Space to turn it off.
