Gitnexus Exploring

reinamaccredy/gitnexus-exploring

Use when the user asks how code works, wants to understand architecture, trace execution flows, or explore unfamiliar parts of the codebase. Examples: \"How does X work?\", \"What calls this function?\", \"Show me the auth flow\

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. gitnexus_query({query: "<what you want to understand>"})  → Find related execution flows
4. gitnexus_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 npx gitnexus analyze in terminal.

Checklist

- [ ] READ gitnexus://repo/{name}/context
- [ ] gitnexus_query for the concept you want to understand
- [ ] Review returned processes (execution flows)
- [ ] gitnexus_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

gitnexus_query — find execution flows related to a concept:

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

gitnexus_context — 360-degree view of a symbol:

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

Example: "How does payment processing work?"

1. READ gitnexus://repo/my-app/context       → 918 symbols, 45 processes
2. gitnexus_query({query: "payment processing"})
   → CheckoutFlow: processPayment → validateCard → chargeStripe
   → RefundFlow: initiateRefund → calculateRefund → processRefund
3. gitnexus_context({name: "processPayment"})
   → Incoming: checkoutHandler, webhookHandler
   → Outgoing: validateCard, chargeStripe, saveTransaction
4. Read src/payments/processor.ts for implementation details

How to use it

Copy the folder

Take reinamaccredy/gitnexus-exploring from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.

Install what it needs

The instructions reference npx. Without those the skill loads but fails at the first command.
