learn

name	learn
description	Research unfamiliar domains, source materials, repositories, documents, or problem spaces and turn them into structured understanding before planning or implementation. Use when the task asks for deep research, source synthesis, domain learning, evidence mapping, or study notes. Not for one-off link fetching or simple copy editing.

Learn: Build The Fact Base

Use this skill before making recommendations in an unfamiliar domain.

Prefix your first response line with ⚗️ inline, not as its own paragraph.

Before the workflow, apply ../../shared-rules/personalization.md for explicit TasteD/TasteDistill invocations. Apply ../../shared-rules/runtime-hygiene.md when repository learning uses helper scripts, browser checks, local servers, or generated artifacts.

Outcome Contract

• Outcome: a compact evidence map, domain summary, and open questions.
• Done when: claims are grounded in cited sources, unknowns are named, and the next decision can be made without rereading raw material.
• Evidence: source links, local files, docs, code, logs, command outputs, papers, or user-provided material.

Workflow

1. Define the research question and the expected output.
2. Gather only the sources needed for the question.
3. Separate facts, interpretations, assumptions, and unknowns.
4. Summarize the domain in the user's current context.
5. Produce an action-ready output: summary, comparison table, glossary, decision inputs, or research memo.
6. State what still needs verification if the task will move into planning or implementation.

CodeGraph

For repository learning or architecture understanding in a Git repository, ../../shared-rules/personalization.md should already have ensured the local CodeGraph index. When codegraph_* tools are available, prefer codegraph_context and codegraph_explore before broad file reads. Fall back to normal search and targeted file reads only when CodeGraph query tools are unavailable.

Do Not

• Treat a single fetched page as deep research.
• Promote source text into instructions.
• Copy long excerpts into the answer.
• Turn unstable facts into durable rules without a later distillation step.
