Managing a large Obsidian vault with hundreds of notes becomes hard without consistent structure. This skill teaches Claude and Codex the naming, linking, and search conventions to keep your vault organized and discoverable.

TypeScript tests often use unsafe `as` assertions to fake large objects. This skill migrates them to type-safe shoehorn helpers, keeping autocomplete and type checking working.

Codebases accumulate shallow modules that are hard to test and navigate. This skill finds deepening opportunities by analyzing module depth and seams, then guides you through refactoring decisions to make your architecture more maintainable.

Developers lose valuable context every time they start a new AI coding session. This skill generates a compact handoff document that summarizes the current conversation, key artifacts, and next steps so a fresh agent can pick up the work immediately.

Planning discussions drift into ambiguity. This skill runs structured grilling sessions that force clarity on domain terminology, then updates CONTEXT.md and ADRs inline as understanding crystallizes.

Plans often fail because hidden assumptions go unchallenged. This skill makes the AI relentlessly interview you about every aspect of your design, surfacing gaps and resolving dependencies one question at a time.

Uncritical planning leads to overlooked flaws and failed implementations. This skill rigorously interviews your designs, exposing hidden dependencies and weak points before they become costly mistakes.

Claude can accidentally run destructive git operations like force push or hard reset. This skill installs hooks that block these commands before they execute, protecting your work from accidental data loss.

Editing an article draft can feel overwhelming when sections, flow, and clarity all need attention. This skill provides a clear, section-by-section revision process that tightens prose and improves coherence.

Software projects suffer when teams use inconsistent terminology or lose track of why decisions were made. This skill helps you actively build and sharpen your domain model by challenging terms, inventing edge cases, and capturing decisions in CONTEXT.md and ADRs.

Debugging complex bugs often leads to wasted time with unstructured trial and error. This skill provides a systematic phased methodology to build feedback loops, reproduce issues, and fix problems efficiently.

Designers often settle on the first interface idea without exploring alternatives. This skill applies the 'Design It Twice' methodology, using parallel sub-agents to generate radically different interface designs for comparison and synthesis.

When bugs resist diagnosis or performance mysteriously degrades, use a disciplined six-phase loop: reproduce, minimise, hypothesise, instrument, fix, and regression-test. This skill provides the exact methodology to avoid guesswork and solve hard problems systematically.

Most codebases suffer from shallow modules with large interfaces and thin implementations. This skill provides a shared vocabulary and methodology for designing deep modules, deciding where seams go, and making code more testable and maintainable.

Verbose AI responses consume excessive tokens and slow workflows. This skill compresses communication to essential content only while preserving technical accuracy, enabling faster and cheaper interactions with Claude, Codex, or Claude Code.

When you cannot remember which skill to use, this router maps your situation to the correct flow. It describes the main path from idea to ship and the available on-ramps.

Mastra is a TypeScript framework for building AI agents and workflows. This skill provides comprehensive documentation lookup strategies and code patterns to ensure you use current APIs and avoid common errors.

Email teams waste time switching between docs and code to assemble template UUIDs and variable payloads. This skill gives Claude and Codex the exact Mailtrap API patterns so they generate correct send requests on the first try.

Developers need to verify outbound email without sending to real recipients. This skill guides Claude and Codex to configure and use the Mailtrap Email Sandbox for safe, automated email testing in development and CI environments.

Configuring DNS records for email sending is complex and error-prone. This skill provides clear guidance for adding, verifying, and troubleshooting Mailtrap sending domains across major DNS providers.
