Hey @thedaviddias 👋
I ran your skills through
tessl skill reviewat work and found some targeted improvements. Here's the full before/after:This PR covers 5 of your 8 skills to keep the contribution focused and reviewable — the remaining 3 (agent-browser at 90%, github-gh at 95%, template-skill placeholder) are already in great shape or intentionally blank.
Changes summary
split-into-references: Added missing YAML frontmatter with name, description, and explicit trigger terms. The skill previously failed validation entirely (no frontmatter = 0% on all judge dimensions).
tdd-methodoly-expert: Removed ~220 lines of verbose TDD textbook content that Claude already knows (Red-Green-Refactor explanations, phase principles, example flows). Consolidated into a tight workflow with explicit validation checkpoints at each phase. Kept the bundled tools section (most valuable part) and added well-signaled references to existing reference files.
brainstorming: Removed the dot graph (won't render in Claude's context), eliminated the triple-redundancy (checklist + process flow diagram + "The Process" section all described the same workflow). Consolidated into a single clear 7-step workflow. Expanded description with specific actions and natural trigger terms.
mcp-builder: Cut ~245 lines of generic software engineering advice (DRY, async/await, error handling concepts Claude already knows). Consolidated reference file listings from 5 separate locations into a single "Load Documentation" section. Kept agent-centric design principles (MCP-specific value) and the critical warning about long-running server processes.
skill-check: Removed the "Testing this skill" section (meta-validation that doesn't help Claude perform the core task). Trimmed commands reference to essential commands. Added specific concrete actions to description (frontmatter schema, required fields, formatting issues, quality scoring with line numbers).
