visualize

A command that creates an interactive HTML map of how parts of a codebase call one another over time.

In plain words
What is it for?
Use it to explore modules, functions, methods, classes, call relationships, cycles, and disconnected code areas, with optional path and size filters.
Why use it?
It makes unfamiliar code easier to navigate by showing recent changes, structure, hotspots, and circular dependencies in one view.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

visualize 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 yesterday.

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.

What it actually says

Generate an interactive temporal call graph visualization that starts with recent movement/onboarding context, then supports module overview, symbol exploration, hotspots, and cycles.

User input: $ARGUMENTS

Parse input for optional parameters:

  • Plain text → directory filter (e.g., /visualize src/services)
  • max=N or "limit N" → sets maxNodes
  • orphans or include-orphans → sets includeOrphans=true
  • No input → visualize recent code movement plus entire call graph

Call index_visualize with parsed parameters.

Examples:

  • /visualize → temporal onboarding view with changes, modules, symbols, hotspots, and cycles
  • /visualize src/tools → only symbols in src/tools/
  • /visualize max=1000 → limit to 1000 nodes
  • /visualize src/indexer orphans → include disconnected nodes

If the index doesn't exist, run index_codebase first.

Return the generated file path and open instructions.

Terminology:

  • Modules are path-based code areas, such as src/tools or native.
  • Symbols are indexed named code units, such as functions, methods, classes, or Rust modules.
  • Cycles are loops where code can eventually call or depend back on itself.
Changes

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.

visualize is a command published in the GitHub repository Helweg/open-codebase-index (183 stars, last pushed 2d ago), licensed MIT. It adds 6 tokens to every session and 275 once invoked, about $0.0000 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
