Explains features, terms, and concepts from a codebase. Use whenever the user asks to explain, describe, or understand something ("explain X", "what is X", "how does X work"). Also use when starting an implementation, refactor, or test task — invoke as `depth:pamphlet <concept>` before writing code, `depth:novella <concept>` before designing an approach, or `depth:novel <concept>` before a deep refactor. Agent-triggered mode (depth: prefix) skips the interview and returns a structured WHAT/WHERE/HOW/CONNECTS TO block instead of a narrative.

Fix and improve this skill with Tessl
tessl review fix ./skills/explain/SKILL.mdThe 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 technology playbook (`technology.md`) instructs the agent to use `WebSearch` and `WebFetch` to retrieve official documentation and READMEs from arbitrary web sources.
