What it does
Start Here is an agent skill from Abilityai/cornelius. Orientation guide - introduces Cornelius, its core capabilities, main use cases, and the abilities marketplace
Its SKILL.md is about 1.8k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Knowledge Management. The repository describes itself as: AI-powered second brain template for Claude Code + Obsidian. The licence is MIT.
When your agent uses it
- Knowledge Management work in your project
Example prompts
- “/start-here”
Requirements
- Docker
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- What Cornelius is - an AI agent that captures the user's original thinking and builds a personal knowledge graph in their Obsidian vault
- What makes it different - most AI gives you the world's knowledge; Cornelius helps you build and access your own knowledge
- The two core tracks - Capture (detect and save original thinking) and Leverage (search, synthesize, create articles)
- Top 3-4 things they can do right now - most useful entry points for a new user

What it can do on your machine
Read from SKILL.md and the folder at commit fd5e9a4. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
claude
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Start Here loads about 1.8k tokens when it runs. Until then it costs about 30 tokens; SKILL.md has 781 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Agent Instructions
You are Cornelius, an Insight Harvester and Second Brain Partner. When this skill is invoked, introduce yourself warmly and clearly explain what you are and what you can do for the user. This is their starting point - treat it as a welcome moment.
Deliver a clear, friendly introduction covering:
- What Cornelius is - an AI agent that captures the user's original thinking and builds a personal knowledge graph in their Obsidian vault
- What makes it different - most AI gives you the world's knowledge; Cornelius helps you build and access your own knowledge
- The two core tracks - Capture (detect and save original thinking) and Leverage (search, synthesize, create articles)
- Top 3-4 things they can do right now - most useful entry points for a new user
- Abilities marketplace - brief overview of available plugins with their specific skills, and how to install them
Keep the tone conversational and inviting. End with an open question asking what they'd like to explore or work on.
Start Here - Welcome to Cornelius
What is Cornelius?
Cornelius is an Insight Harvester and Second Brain Partner - a Claude Code agent designed to capture your original thinking and help you leverage it over time.
Most AI assistants help you access the world's knowledge. Cornelius does something different: it helps you build and access your knowledge - your frameworks, your perspectives, your connections between ideas.
It lives inside your Obsidian vault and treats it as a knowledge graph, not just a file system.
How It Works
Cornelius operates on two tracks:
1. Capture - When you talk through ideas, read papers, or have realizations, Cornelius detects the moments of original thinking and saves them as atomic permanent notes in your vault. Not summaries - your actual voice and reasoning patterns.
2. Leverage - Your captured notes become retrievable. Cornelius can search semantically, find non-obvious connections across domains, synthesize your thinking into articles, or answer questions grounded in what you've already figured out.
Under the hood, it uses a local FAISS vector index over your Brain folder with spreading activation search - so retrieval improves the more you use it.
Main Use Cases
| Use Case | How |
|---|---|
| Capture a realization | Just say it out loud - Cornelius detects when you're thinking originally and saves it |
| Search your knowledge | /recall <topic> - 3-layer semantic search across your vault |
| Find unexpected connections | /auto-discovery - surfaces cross-domain links you weren't looking for |
| Write an article | /create-article <topic> - synthesizes your permanent notes into a draft |
| Get advice grounded in your thinking | /advise - any problem statement pulls relevant KB insights first |
| Extract insights from a document | /extract-document-insights <file> - processes papers, books, reports |
| Extract insights from your own content | /extract-insights <file> - processes your conversations, transcripts, notes |
| Deep research on a topic | /deep-research <topic> - discovers, extracts, and integrates new insights |
| Run a dialectic | /dialectic <question> - two committed positions stress-test your idea |

Abilities Marketplace
Cornelius supports installable plugins from the Ability AI marketplace - modular capability packs you can add without touching core agent config.
Available Plugins
| Plugin | What It Adds | Skills You Get |
|---|---|---|
| trinity-onboard | Deploy any agent to Trinity - sovereign, self-hosted AI infrastructure with cron scheduling, multi-agent orchestration, approval gates, and audit trails. Same agent runs locally (interactive dev) and remotely (scheduled/always-on), synced via Git. | /request-trinity-access, /trinity-onboard, /credential-sync, /trinity-sync, /trinity-remote, /trinity-schedules |
| playbook-builder | Create structured, transactional playbooks with state management - autonomous, gated, or manual execution modes | /create-playbook, /save-playbook, /adjust-playbook |
| dev-methodology | Documentation-driven development: 5-phase cycle (context → develop → test → docs → PR), 14 skills, 3 sub-agents | /dev-methodology:init, /read-docs, /implement #N, /validate-pr N |
| utilities | Ops workflows for SSH/Docker services: incident investigation, safe deploys, log management, conversation saving | /investigate-incident, /safe-deploy, /docker-ops, /save-conversation |
Trinity: Deploying Your Agent
Install first:
claude plugin add abilityai/abilities && claude plugin install trinity-onboard@abilityaiOnce installed, the workflow is: ACCESS → ADOPT → SYNC → SCHEDULE
/request-trinity-access- get credentials (self-host or managed by Ability AI)/trinity-onboard- create required files for Trinity compatibility/trinity-sync push- deploy agent state to remote via Git/trinity-schedules schedule my-skill "0 9 * * *"- schedule recurring autonomous runs
Installing a Plugin
From your terminal (recommended):
# First time - add the Ability AI marketplace
claude plugin add abilityai/abilities
# Then install a plugin
claude plugin install trinity-onboard@abilityai
claude plugin install playbook-builder@abilityai
claude plugin install dev-methodology@abilityai
claude plugin install utilities@abilityaiOr from inside a Claude Code session:
/plugin marketplace add abilityai/abilities
/plugin install trinity-onboard@abilityaiUpdating Plugins
# Update a specific plugin
claude plugin update trinity-onboard@abilityai
# Update all installed plugins
claude plugin update --allCheck What's Installed
ls ~/.claude/plugins/cache/abilityai/After Installing: First Command to Run
| Plugin | Run This First | What It Does |
|---|---|---|
| trinity-onboard | /request-trinity-access | Get credentials for a Trinity instance (self-host or managed) |
| playbook-builder | /create-playbook | Build your first structured, reusable workflow |
| dev-methodology | /dev-methodology:init | Initialize docs-driven dev cycle in your project |
| utilities | /save-conversation or /investigate-incident | Ops tools - use as needed |
Where to Go Next
