onboard

A codebase orientation briefing created by indexing the project and examining its structure, complexity, dependencies, and change hotspots.

In plain words
What is it for?
Use it to learn the project’s size and layout, central modules, complex functions, risky files, dependency impact, and where testing or review should begin.
Why use it?
It gives developers unfamiliar with a project a practical map before they start making changes.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Made for: Claude Code.

Per session 0 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 175 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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

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 yesterday.

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

Index this codebase with Suitable Loop and give me a complete orientation.

Steps:

  1. Use index_codebase to index the current project directory (use force=true if already indexed)
  2. Use codebase_summary to get high-level stats
  3. Use complexity_report (top 10) to find the most complex code
  4. Use hotspot_report on this repo to find high-risk areas
  5. Check blast_radius on the top 3 hotspot files

Then give me a concise briefing covering:

  • Project size and structure (files, functions, classes)
  • The most connected/central modules
  • The most complex functions (and why they matter)
  • The highest-risk hotspots (high churn + high dependency count)
  • Which files have the largest blast radius
  • Recommendations for where to focus testing and review
Changes

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.

onboard is a command published in the GitHub repository suitable-adventures/suitable-loop (0 stars, last pushed 5mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 175 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
