In plain words
What is it for?
Use it to learn what Trinity is, choose between setup paths, connect an instance, configure the agent, and verify that it responds.
Why use it?
It gives beginners a resumable path through the setup process and checks each stage with a live test.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

start-here scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

How it starts

The opening of the file, as written. The whole thing — 204 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Trinity — Start Here

ℹ️ First, set expectations: before anything else, print one short line with this skill's version and its most recent change — the top entry of metadata.changelog above — e.g. start-here vX.Y — recent: <summary>. Then proceed.

The front door to Trinity. One command walks a newcomer from "what is this?" to "my first agent answered me from my own instance" — and costs nothing until they explicitly choose a step that deploys something.

Design rules (bind every stage):

  1. Route, don't duplicate. Every operational step belongs to a specialist skill — /trinity:connect, /trinity:deploy-new-instance, /trinity:onboard, /create-agent:create, /agent-dev:agent-fleet-analysis. This skill sequences them and carries the user's state; it never re-implements their flows.
  2. Live documentation over static claims — at every stage. Never improvise platform facts from memory. Two grounded channels cover the whole journey (see Live documentation channels below): before any instance exists, the public Trinity Docs Q&A endpoint and the live docs/user-docs index on GitHub; after connecting, the instance's own mcp__trinity__ask_trinity. The short Stage 0 block is a network-down fallback, not the source of truth.
  3. Zero commitment until chosen. The tour door deploys nothing and asks for no credentials. Stages that create or deploy things happen only after the user picks them.
  4. Always resumable. State persists across sessions; re-running this skill continues where the user left off.

Live documentation channels

Pre-connect (no instance, no auth, works from any laptop):

  1. Trinity Docs Q&A — a public endpoint backed by Vertex AI Search over the platform's docs/user-docs/**, onboarding docs, and the Trinity Compatible Agent Guide, re-indexed automatically on every push to the platform's main branch — always current:

    curl -sS -m 30 -X POST -H "Content-Type: application/json" \
      "https://us-central1-mcp-server-project-455215.cloudfunctions.net/ask-trinity" \
      -d '{"question": "<the user'\''s question>"}'

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
