diagnose 是做什么的？
用于复杂错误和性能回退的有纪律诊断循环。重现 → 最小化 → 假设 → 检测 → 修复 → 回归测试。当用户说“诊断这个”/“调试这个”、报告错误、说某个东西坏了/抛异常/失败，或描述性能回退时使用。

mattpocock/diagnose 是一个用于处理复杂错误和性能回退的规范化诊断工具，适用于 Claude Code、Cursor 和 Codex 等 AI 代理平台。它基于一个六步循环（重现 → 最小化 → 假设 → 检测 → 修复 → 回归测试）运行，帮助开发者系统性地定位并解决棘手问题。该技能特别强调最小化步骤，通过剥离非关键代码和依赖，快速找到问题的核心触发条件；然后结合日志、调试器和静态分析工具进行假设验证和修复。它还内置了回归测试机制，确保修复不会在后续引入新问题。此工具适合在用户提出“诊断这个”、“调试这个”、报告错误、描述性能回退或异常时启用，旨在将无序的调试过程转化为可重复、可验证的工程实践。

This repo contains 20 individual skills — each has its own dedicated page.
Ask which skill or flow fits your situation. A router over the skills in this repo.
Ultra-compressed communication mode. Cuts token usage ~75% by dropping filler, articles, and pleasantries while keeping full technical accuracy. Use when user says "caveman mode", "talk like caveman", "use caveman", "less tokens", "be brief", or invokes /caveman.
Hand the current conversation off to a fresh background agent that picks up the work immediately.
Shared vocabulary for designing deep modules. Use when the user wants to design or improve a module's interface, find deepening opportunities, decide where a seam goes, make code more testable or AI-navigable, or when another skill needs the deep-module vocabulary.
Generate multiple radically different interface designs for a module using parallel sub-agents. Use when user wants to design an API, explore interface options, compare module shapes, or mentions "design it twice".
Diagnosis loop for hard bugs and performance regressions. Use when the user says "diagnose"/"debug this", or reports something broken/throwing/failing/slow.
Build and sharpen a project's domain model. Use when the user wants to pin down domain terminology or a ubiquitous language, record an architectural decision, or when another skill needs to maintain the domain model.
Edit and improve articles by restructuring sections, improving clarity, and tightening prose. Use when user wants to edit, revise, or improve an article draft.
Set up Claude Code hooks to block dangerous git commands (push, reset --hard, clean, branch -D, etc.) before they execute. Use when user wants to prevent destructive git operations, add git safety hooks, or block git push/reset in Claude Code.
Grill the user relentlessly about a plan or design. Use when the user wants to stress-test a plan before building, or uses any 'grill' trigger phrases.
Interview the user relentlessly about a plan or design until reaching shared understanding, resolving each branch of the decision tree. Use when user wants to stress-test a plan, get grilled on their design, or mentions "grill me".
Grilling session that challenges your plan against the existing domain model, sharpens terminology, and updates documentation (CONTEXT.md, ADRs) inline as decisions crystallise. Use when user wants to stress-test a plan against their project's language and documented decisions.
Compact the current conversation into a handoff document for another agent to pick up.
Implement a piece of work based on a PRD or set of issues.
Implement a specification in code.
Scan a codebase for deepening opportunities, present them as a visual HTML report, then grill through whichever one you pick.
Grill me about specs for the workflows I want to build, within this workspace.
Migrate test files from `as` type assertions to @total-typescript/shoehorn. Use when user mentions shoehorn, wants to replace `as` in tests, or needs partial test data.
Search, create, and manage notes in the Obsidian vault with wikilinks and index notes. Use when user wants to find, create, or organize notes in Obsidian.
Build a throwaway prototype to flesh out a design — a runnable terminal app for state/business-logic questions, or several radically different UI variations toggleable from one route.
Send and manage iMessages via BlueBubbles, including attachments, tapbacks, edits, replies, and groups.
Control Eight Sleep pods (status, temperature, alarms, schedules).
BluOS CLI (blu) for discovery, playback, grouping, and volume.
Create, search, and manage Bear notes via grizzly CLI.
Capture frames or clips from RTSP/ONVIF cameras.
Search GIF providers with CLI/TUI, download results, and extract stills/sheets.
