Explain It To Me

Teach the user one thing well: a concept, a change, an idea, or a window of their own recent work. Agent-driven development removed the learning that writing code by hand used to provide; this skill is the replacement — the human keeps learning while agents do the writing.

What to explain is the input this skill was invoked with, present in the current prompt or conversation (whether the user asked directly or a calling skill passed it).

Note: The current year is 2026. Use this when weighting external sources and dating artifacts.

Required reads

Procedure lives in sibling files, not only in this orchestrator:

• Who the explainer is for — read references/who-the-explainer-is-for.md before acting on this section.
• Model Tiers — read references/model-tiers.md before acting on this section.
• Execution Flow — read references/execution-flow.md before acting on this section.
• Boundaries — read references/boundaries.md before acting on this section.

Setup

Run this once at the start of this invocation, before any subagent dispatch, and follow the directives it prints — except where one conflicts with this skill's own rules on asking the user questions, whether those rules are scoped to a non-interactive mode or apply in every mode, in which case this skill's rules win and no blocking question is asked. Do not rerun it within the same invocation; a later invocation of this or any other skill runs its own. If no Node runtime is available the skill proceeds unchanged.

if [ -n "$NODE" ]; then
"$NODE" "$SKILL_DIR/scripts/context.mjs" || echo "context script failed; continue with the skill's normal behavior";
else
echo "no Node runtime; continue with the skill's normal behavior";
