Aio Map

Map — Structural Analysis

Environment

• GitNexus: !npx gitnexus status 2>/dev/null && echo "AVAILABLE" || echo "NOT INSTALLED"

Build a dependency and symbol map for files identified by /discover. Uses GitNexus for overview, LSP for precision.

Prerequisites

• GitNexus indexed (npx gitnexus analyze) — verify with npx gitnexus status
• LSP servers running (TypeScript/Rust)

Workflow

Step 1: Symbol inventory (GitNexus) — run in parallel

For each relevant file from discovery, use the GitNexus MCP context tool:

context(file)

Fast overview of symbols and dependencies without reading the full file.

Step 2: File dependencies (GitNexus) — run in parallel

context(file)  → imports and dependents for the file
impact(file)   → what does changing this file affect?

Note: GitNexus tracks TS imports well. For Rust modules, fall back to LSP.

Step 3: Precise references (LSP)

For key functions that will be modified:

lsp_find_references(file, line, character)  → all call sites
lsp_goto_definition(file, line, character)  → where defined
lsp_hover(file, line, character)            → type info

LSP is authoritative — always trust LSP over GitNexus for caller/callee data.

Step 4: Output structural map

## Map: [feature area]

### File: `path/file.ts` (N functions)
**Key functions:** fn1, fn2, fn3
**Imports:** file-a.ts, file-b.ts
**Imported by:** file-c.tsx, file-d.tsx
**References:**
- `fn1` called from: file-c.tsx:42, file-d.tsx:88

### Dependency Graph
file-a → file-b → file-c
                 ↘ file-d

### Blast Radius
Changing `fn1` affects: [list of downstream files]

### Next Step
Run `/plan` to synthesize into implementation plan.

Tool priority

1. GitNexus context — fast file overview (always works)
2. GitNexus impact — blast radius / downstream effects
3. LSP lsp_find_references — precise function-level tracing
4. LSP lsp_hover — type information when needed
