gitnexus-exploring

A GitNexus workflow for learning how an unfamiliar codebase is structured and how its execution flows work. GitNexus is a code-search and execution-tracing tool.

In plain words
What is it for?
Use it to explore project structure, trace authentication or database flows, identify callers and callees, and understand how a feature works.
Why use it?
It helps you find the components, symbols, callers, and processes behind a feature without reading the whole repository first.

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

gitnexus-exploring 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.

Exploring Codebases with GitNexus

When to Use

  • "How does authentication work?"
  • "What's the project structure?"
  • "Show me the main components"
  • "Where is the database logic?"
  • Understanding code you haven't seen before

Workflow

1. READ gitnexus://repos                          → Discover indexed repos
2. READ gitnexus://repo/{name}/context             → Codebase overview, check staleness
3. query({search_query: "<what you want to understand>"})  → Find related execution flows
4. context({name: "<symbol>"})            → Deep dive on specific symbol
5. READ gitnexus://repo/{name}/process/{name}      → Trace full execution flow

If step 2 says "Index is stale" → run node .gitnexus/run.cjs analyze in terminal.

Checklist

- [ ] READ gitnexus://repo/{name}/context
- [ ] query for the concept you want to understand
- [ ] Review returned processes (execution flows)
- [ ] context on key symbols for callers/callees
- [ ] READ process resource for full execution traces
- [ ] Read source files for implementation details

Resources

Resource What you get
gitnexus://repo/{name}/context Stats, staleness warning (~150 tokens)
gitnexus://repo/{name}/clusters All functional areas with cohesion scores (~300 tokens)
gitnexus://repo/{name}/cluster/{name} Area members with file paths (~500 tokens)
gitnexus://repo/{name}/process/{name} Step-by-step execution trace (~200 tokens)

Tools

query — find execution flows related to a concept:

query({search_query: "payment processing"})
→ Processes: CheckoutFlow, RefundFlow, WebhookHandler
→ Symbols grouped by flow with file locations

context — 360-degree view of a symbol:

context({name: "validateUser"})
→ Incoming calls: loginHandler, apiMiddleware
→ Outgoing calls: checkToken, getUserById
→ Processes: LoginFlow (step 2/5), TokenRefresh (step 1/3)

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.
