Use when someone wants to turn a problem, a messy or sprawling skill, or some existing work into well-shaped reusable context for their agent. Triggers include "help me make a skill for X", "my skill is a mess, sort it out", "I want to get more out of Tessl with this skill", or "package this so my team can use it". Runs the arc - understand the problem, gather the artifacts, plan the right composition, build it - then points to eval as a separate next step.

The canonical home for this skill is tessl/plugin-creator
The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.
The workflow involves gathering artifacts based on user pointers (such as PRs), which can lead to ingesting outsider-authored content via active search/fetch.
