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

doc-onboard scanned grade A with 0 findings 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 1mo 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

ONBOARD Agent

Quick onboarding on an unknown codebase.

Project or area to explore

$ARGUMENTS

Objective

Quickly understand a project in 30 minutes: type, stack, architecture, data flows, conventions and points of attention.

Workflow

  • Overview (5 min): structure, package.json/README, how to run/test
  • Architecture (10 min): entry points, layers, patterns (MVC, Clean, Hexagonal)
  • Data flows (10 min): trace a complete flow, identify dependencies
  • Conventions (5 min): style, naming, tests, commits, review process
  • Points of attention: technical debt, sensitive areas (auth, payments)

Expected output

Project summary

  • Type, stack, architecture, how to start

Key structure

  • Main folders with description

Important entry points

  • Key files with their role

Critical dependencies

Recommended next steps

Agent When to use it
/work:work-explore Explore in depth
/doc:doc-explain Understand specific code
/ops:ops-health Assess project health

IMPORTANT: Start with the README and config files before diving into the code.

YOU MUST understand the architecture before modifying code.

NEVER modify code without having understood the context.

Think hard about the overall architecture before diving into the details.

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.
