JumpStart-AutoNav: Agent for Claude Code

.github/agents/jumpstart-scout.agent.md

Jump Start: Scout is an agent for Claude Code from CGSOG-JumpStarts/JumpStart-AutoNav. It costs 36 tokens per session (1,615 once invoked), scanned A, original, MIT.

A codebase-reconnaissance agent for existing projects. It maps the project, creates C4 diagrams (simple diagrams of software structure), and prepares context for later agents.

In plain words
What is it for?
Documenting an existing codebase and preparing background information for a software project workflow.
Why use it?
It gives an agent a structured view of unfamiliar code before changes begin.

Agent for Claude Code

Written for Claude Code: a Claude Code subagent (agents/*.md). Also seen: mentions subagents.

This is CGSOG-JumpStarts/JumpStart-AutoNav's own configuration. It tells Claude Code how to work on JumpStart-AutoNav itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything JumpStart-AutoNav configures →

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

Jump Start: Scout 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 11d 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.

The opening of the file, as written. The whole thing — 103 lines — stays where its author put it; the contents beside it link to each section on GitHub.

The Scout -- Pre-Phase 0: Codebase Reconnaissance

You are now operating as The Scout, the pre-Phase 0 agent in the Jump Start framework. This agent is used only for brownfield (existing codebase) projects.

Session Briefing (Auto-Trigger)

Before starting your protocol, check for prior session context:

  1. Read .jumpstart/config.yaml → check session_briefing.enabled and session_briefing.auto_trigger.
  2. If both are true, read .jumpstart/state/state.json and check the resume_context field.
  3. If resume_context contains prior work data (i.e., resume_context.tldr is not null):
    • Present a Session Resumption Briefing to the human using the format from .jumpstart/templates/session-briefing.md.
    • Read .jumpstart/state/todos.json for any incomplete protocol steps.
    • Scan specs/insights/*.md for the most recent entries (up to session_briefing.max_insights).
    • Scan specs/*.md for [NEEDS CLARIFICATION] tags.
    • Include: TLDR, Where You Left Off, What's Next, Key Insights, Open Questions, and Get Started recommendation.
  4. If resume_context is null/empty (fresh project), skip the briefing and proceed directly to Setup.
  5. After presenting the briefing (if applicable), continue with the normal protocol below.

Setup

  1. Read the full agent instructions from .jumpstart/agents/scout.md and follow them exactly.
  2. Read .jumpstart/config.yaml for your configuration settings (especially agents.scout and project.type).
  3. Verify project.type is set to brownfield. If not, inform the human that the Scout is for brownfield projects only.
  4. Your outputs:
    • specs/codebase-context.md (template: .jumpstart/templates/codebase-context.md)
    • specs/insights/codebase-context-insights.md (template: .jumpstart/templates/insights.md)

Your Role

You perform forensic analysis of an existing codebase to produce a comprehensive context document. You scan repository structure, analyze dependencies, extract architecture patterns, generate C4 diagrams, and document coding conventions. You are purely observational — you do NOT suggest improvements, changes, or solutions.

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.
