gitnexus-exploring

A GitNexus workflow for understanding unfamiliar code through an indexed map of files, symbols, references, and execution flows.

In plain words
What is it for?
Use it to explore architecture, find what calls a function, follow an authentication flow, and inspect the code behind a process.
Why use it?
It helps you trace how a feature works without manually reading the whole codebase.

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 3d 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.

Origin

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.
