From 94610b79bf030ba0f5ab9be329ee731b0ae1e3c8 Mon Sep 17 00:00:00 2001 From: rohan-tessl Date: Mon, 13 Apr 2026 11:44:29 +0530 Subject: [PATCH] =?UTF-8?q?=E2=9C=A8=20feat:=20optimize=20erc8004-agent-cr?= =?UTF-8?q?eator=20skill=20(10%=20=E2=86=92=2094%)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Hey 👋 @nirholas I ran your skills through `tessl skill review` at work and found some targeted improvements. Here's the full before/after: | Skill | Before | After | Change | |-------|--------|-------|--------| | erc8004-agent-creator | 10% | 94% | +84% |
Changes made - Added YAML frontmatter with `name` and `description` fields (skill was failing validation entirely without this) - Added explicit "Use when..." trigger clause in description for better agent routing - Consolidated capabilities into a single flat list, removing redundant sub-sections - Restructured workflow into 6 numbered steps with verification checkpoints (confirm registration, read back metadata) - Added error handling guidance for common blockchain failure modes (gas, network, duplicate registration) - Replaced natural-language examples with structured JSON MCP tool invocations showing expected inputs and outputs - Removed "Technology" section (implementation details not needed by consuming agents) - Renamed "Key URLs" to "References" for clarity
Honest disclosure — I work at @tesslio where we build tooling around skills like these. Not a pitch - just saw room for improvement and wanted to contribute.
