onboard-context-provider

onboard-context-provider is a skill for Claude Code, Codex from smicolon/ai-kit. It costs 63 tokens per session (753 once invoked), scanned A, original, MIT.

A project-aware guide that uses an engineer's onboarding profile to explain unfamiliar technologies, project conventions, and expected code patterns.

In plain words
What is it for?
It helps answer questions about how to do things, where to place code, and which conventions to follow. It can also flag code that does not match the project's established patterns.
Why use it?
It reduces confusion when someone is new to a codebase by tailoring explanations to what they already know and where they have knowledge gaps.

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-context-provider 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.

How it starts

The opening of the file, as written. The whole thing — 99 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Onboard Context Provider

Provides personalized explanations and assistance based on the engineer's background from their onboarding profile.

Activation Triggers

This skill activates when:

  • Engineer asks "how do I..." or "where do I put..." questions
  • Engineer asks about project conventions or patterns
  • Code written doesn't match project conventions (imports, naming, structure)
  • Engineer seems confused about a technology in their knowledge gaps list

Profile Location

.claude/onboard-profile.local.md

If this file doesn't exist, this skill does nothing. The engineer needs to run /onboard first.

Behavior

1. Read Engineer Profile

Check .claude/onboard-profile.local.md for:

  • Primary Stack: What they know well
  • New To: What's unfamiliar
  • Knowledge Gaps: Specific gaps with priority levels
  • Current Task: What they're working on

2. Personalize Response

Based on the profile, adjust explanations:

If the concept is in their knowledge gaps (NEW):

  • Explain using analogies to their primary stack
  • Show a side-by-side comparison with what they know
  • Point to an example file in the codebase

If the concept is related to something they know (TRANSFERABLE):

  • Briefly note the difference, skip the basics
  • Focus on what's different, not what's the same

If they already know it (FAMILIAR):

  • Don't explain the concept at all
  • Just show the project-specific convention

3. Always Include

  • Specific file paths from this project as examples
  • The project convention (from CLAUDE.md) for whatever they're doing
  • A concrete next action they can take

Personalization Strategies

Backend Engineer → Frontend Project

Concept Explain As
Components "Like views that return HTML directly"
State (useState) "Like a variable that re-renders the page when changed"
Props "Like function arguments for components"
useEffect "Like Django signals — side effects triggered by changes"
Client vs Server Components "Server = Django view, Client = JavaScript in template"
