Second Brain Write Agent Skill

Write from the vault

The research is already done, cited and connected. What is left is the argument,

and that is the part the user should keep.

Core rule

Assemble structure and evidence. Do not hand back finished prose as if it were

theirs.

Workflow

• Find the relevant concept pages and say what they collectively argue.
• Surface the disagreements. These are where the user has something to say

that is not the consensus view, and they are the most useful part of the

outline.

• Build the outline from pages, each point tied to the page behind it.
• Mark the weak points: claims resting on one source, self-reported

figures, anything the vault flags as unverified.

• Draft only if asked, and say plainly that the phrasing is a first pass to

be rewritten in their voice.

• Offer to ingest the finished piece back as a source once published.

Output format

Angle: <what this piece argues that the sources do not individually>
Outline:
  1. <point> - [[page]], [[page]]
Weak points: <claims with thin support>
Missing: <what would strengthen it>

Calibration

If every point in the outline comes from one page, this is a summary of that

page, not an article. Say so.

Never introduce a specific number or quote that has no source page behind it.

That is the failure mode of writing with a model, and in a cited piece it is

the one that costs the most.
