component-onboarding

A command that creates an onboarding guide for a specific software component, meaning one part of a larger application. The guide explains the component's role, related code, learning path, and practical exercises.

In plain words
What is it for?
Use it to prepare component walkthroughs, training material, hands-on exercises, or targeted knowledge-transfer documentation.
Why use it?
It reduces the time a new developer needs to understand unfamiliar code and how that code fits into the wider system.

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 176 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

component-onboarding 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 2d 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

Component-Specific Onboarding

Generate detailed onboarding guide for: $ARGUMENTS

This command creates comprehensive onboarding materials for a specific component by:

  1. Identifying the component and its role in the system
  2. Mapping learning paths based on code relationships
  3. Generating detailed code walkthroughs and explanations
  4. Creating hands-on exercises and examples
  5. Providing context-aware documentation

Follow these steps:

  1. Use nodes-semantic-search to find the specific component and related functionality
  2. Get implementation details with get-code for the component
  3. Map learning dependencies with get-usage-dependency-links
  4. Find logical code flow with find-direct-connections
  5. Search for existing documentation with docs-semantic-search
  6. Generate structured component-specific onboarding guide

This command is ideal for: component-specific training, feature understanding, and targeted knowledge transfer.

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.
