Second Brain Report Agent Skill

>- pages, name the gaps, and write findings with citations, disagreements and limits. Use this skill when the user asks for a research report, a deep write-up on a topic, or wants to understand a subject thoroughly using what they have collected. Do NOT use for a quick answer from the vault, for drafting an article in the user's voice, or for summarising a single source.

The instruction itself

5 sections, as written by the author

Write a research report

A report that presents only findings looks stronger and is less useful, because

the reader cannot tell where it is load-bearing and where it is thin.

Core rule

Scope against the vault first. Most of the work in a good report is knowing what

you do not need to look up.

Workflow

  • Inventory what exists. Which pages cover this, what is thin, what is

missing entirely. That answer is the research plan.

  • Report the gaps before writing, so the user can decide whether to ingest

more first.

  • Write from pages, citing pages. Every claim traces to a source page with

a URL behind it.

  • Record disagreement where sources conflict, with dates and who says what.
  • State what could not be established and what evidence would change the

conclusion.

  • Save to output/ and offer to ingest it back as a source.

Output format

## Question
## What the vault covers    (with [[page]] citations)
## Where sources disagree
## What I could not establish
## What would change this
## Pages read: <list>

Calibration

If the vault covers less than half the question, say so at the top rather than

producing a report that reads as complete.

Never fill a gap from general knowledge without labelling it as outside the

vault. A report whose sources cannot be checked is worth less than a short one

that can.

How to use it

Copy the folder

Take undefined-ui/second-brain-report from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.
