Explore the ARCAS Systems Second Brain

Sales & growth

• Proposals

  Scoped, priced, and written in your voice.

  Reads from your second brain

  • proposal-writer/
    • SKILL.md
  • core/
    • voice-profile.yml
  • brain/
    • knowledge/

  “A proposal that mirrors the client's own words wins more than one that describes the service.”

• Outreach

  First lines that earn a reply.

  Reads from your second brain

  • email-drafter/
    • SKILL.md
  • core/
    • voice-profile.yml

  “Emails that sound like you sent them, not like a marketing tool did.”

• Prospects

  Each new lead captured the same way, ready when you write the proposal.

  Reads from your second brain

  • prospect-init/
    • SKILL.md
  • companies/
    • prospects/<slug>.md

  “Captures the minimum prospect intel in one short flow, so the next time you write a proposal the context exists at a predictable path instead of scattered across your notes.”

• Lists

  A clean list before outreach, so every name is worth the message.

  Reads from your second brain

  • list-pruner/
    • SKILL.md

  “A list full of duplicates and half-filled rows turns a focused outreach week into busywork. Scoring and de-duping it up front means every row you contact is worth contacting.”

Marketing & content

• Content

  One idea, shaped for every channel.

  Reads from your second brain

  • content-repurposer/
    • SKILL.md
  • core/
    • voice-profile.yml

  “One piece of thinking, multiplied across every channel without rewriting it from scratch.”

• LinkedIn posts

  Your point of view, in your words.

  Reads from your second brain

  • linkedin-post/
    • SKILL.md
  • core/
    • voice-profile.yml
  • brain/
    • log.md

  “Posts grounded in your actual situation this week, written in your voice.”

• Campaigns

  One theme turned into a campaign that knows who it is for.

  Reads from your second brain

  • campaign-from-theme/
    • SKILL.md
  • brands/
    • <slug>/voice.yml
    • <slug>/positioning.yml

  “The gate is the value. It forces audience and objective clarity before any draft, which is what makes the output usable on the first attempt.”

• Replies

  Reviews and DMs answered in the right voice, fast.

  Reads from your second brain

  • review-responder/
    • SKILL.md
  • brands/
    • <slug>/voice.yml
  • core/
    • voice-profile.yml

  “A reply in the wrong voice erodes trust. This makes the right-voice reply the default rather than the careful effort.”

Operations & delivery

• SOPs

  The work documented so the next person just runs it.

  Reads from your second brain

  • sop-writer/
    • SKILL.md
  • your files
    • stack.json

  “A process documented so it runs without the founder in the room.”

• Client updates

  Where things stand, before they ask.

  Reads from your second brain

  • client-update/
    • SKILL.md
  • core/
    • voice-profile.yml
  • context/
    • clients.md

  “Clients kept informed without writing from scratch each time, so the relationship never goes silent.”

• Meetings

  Walk in knowing what you last agreed and what is still open.

  Reads from your second brain

  • meeting-prep/
    • SKILL.md
  • context/
    • clients.md
  • brain/
    • .snapshot.md

  “A brief built from your own prior context, not a generic one. Knowing what you already committed to with this person is what makes the meeting productive.”

• Ship-ready check

  A last pass before anything client-facing leaves your laptop.

  Reads from your second brain

  • ship-deliverable/
    • SKILL.md
  • your-deliverable-template/
    • SKILL.md
  • pre-send-check/
    • SKILL.md

  “Composes four checks that are easy to skip individually under deadline pressure into one pass, so nothing ships with an AI phrase, missing asset, or unreviewed blind spot.”

Strategy & finance

• Decision frameworks

  The way you weigh a call, reused.

  Reads from your second brain

  • decision-framework/
    • SKILL.md
  • core/
    • identity.md

  “Breaks the loop of circling the same call by naming what you are choosing and what each option costs.”

• Unit economics

  The numbers under the deal, before you commit.

  Reads from your second brain

  • unit-economics/
    • SKILL.md
  • finance/
    • <period>/summary.md

  “The math shown with its assumptions and scenarios, not a single number you can misread.”

• Market analysis

  The market read grounded in what you already know.

  Reads from your second brain

  • strategic-analysis/
    • SKILL.md
  • brain/
    • knowledge/
    • .snapshot.md

  “Grounds competitive and market analysis in your actual position and prior knowledge, rather than a generic table that ignores what you already know or have decided.”

• Finance import

  A messy bank export turned into numbers the brain can read.

  Reads from your second brain

  • finance-import/
    • SKILL.md
  • finance/
    • <period>/summary.md

  “A bank or accounting CSV is unreadable to the OS as-is. This turns one export into a clean markdown mirror your other skills can cite, without ever touching the source system.”
