LLM Mart Trusted

A Claude skill that reviews a diff by trying to refute each finding before reporting it.

A prompt that forces Gemini to cite sources and flag uncertainty instead of guessing.

A workflow that makes DeepSeek state a hypothesis and a test before proposing any fix.

A Cursor recipe that writes a characterization test before each refactor step.

A skill that keeps a consistent persona and memory across a long MiniMax conversation.

Turns a staged diff into a clean Conventional Commits message — correct type, tight subject, useful body.

Uses ChatGPT search plus an adversarial verification pass to turn a fuzzy question into a sourced brief you can hand to someone else.

Forces Codex CLI to show the diff, review its own changes, run focused validation, and list uncertainty before you keep the patch.

A review skill that makes Copilot focus on concrete behavior changes, missing tests, and repo instructions instead of generic style chatter.

A starter layout for .github/copilot-instructions.md, path-specific instruction files, and AGENTS.md so Copilot stops guessing how your repo works.

Use /setupTests, /tests, and /fixTestFailure in a red-green loop instead of asking Copilot to “add some tests” and hoping for the best.

Forces a failing test that reproduces the bug before any fix — so you know it's actually fixed.

A reusable test harness for checking whether a custom GPT actually follows its instructions, uses tools correctly, and fails safely.

A structured security pass over a diff — checks the OWASP-relevant classes, ranks by exploitability, and shows a repro.

Stops the model from coding too early — lock a short spec and a test list before a single line is written.

The whole public catalogue is an MCP server and a REST API, so your agent can search skills, tools and slash-commands as native tools. Setup is one config block. Plus a private vault that carries your own prompts between machines.

You wouldn't ship a function you ran once. Here's the smallest evaluation setup that catches real regressions — five cases, three graders, and a rule for when to add a sixth.

AGENTS.md, CLAUDE.md, copilot-instructions.md and .cursor/rules all solve the same problem. Most of them are written badly. Here's what changes agent behaviour and what's decoration.

Sanitizing output protects your page. It does nothing for an agent that reads a poisoned README and then runs a command. A practical model of the threat, and what actually helps.

The words are used interchangeably and they shouldn't be. Six categories, what actually distinguishes them, and how to tell which one you're holding.

Most prompts are lucky one-offs. The ones that keep working share a structure: an explicit role, a checklist of constraints, a worked example, and a self-check step. Here's how to build one.

Draft a plan in an ultraplan session and review it in your browser.

Create or apply a methodology such as SWOT or StoryBrand.

Archive the current session and exit Codex without deleting its transcript.

Build a pros-and-cons table.

Sign out of your Cursor account.

Enable or disable the advisor tool that consults a second model for guidance.

View and manage everything running in the background.

Identify patterns and insights from text or data.

Grant the Windows sandbox read access to an additional absolute directory path.

Configure which fields appear in the terminal window or tab title.

Show a quick reference and basics of using GitHub Copilot.

Make the text sound more natural and less robotic.

Exit the CLI immediately; same effect as /exit.

Analyze the task from the perspective of a UX expert.

Enable or disable Vim keyboard bindings.

Submit feedback, report a bug, or share your conversation.

OpenAI's general-purpose assistant for writing, research, coding, data analysis, and agentic tasks.

GitHub's AI pair programmer for inline suggestions, chat, agent mode, and code review across your editor and GitHub.

Anthropic's agentic CLI that edits code, runs tools, and ships changes.
