At a glance

Visualize Rust function call graphs using LSP. An agent skill from fjrevoredo/mini-diarium.

Works in 3 steps: Prepare Call Hierarchy → Incoming Calls (Who calls this?) → Outgoing Calls (What does this call?)
Tasks that involve Codebase onboarding
SKILL.md covers Usage, LSP Operations, Workflow and Output Format, plus 4 more sections
Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Rust Call Graph is an agent skill from fjrevoredo/mini-diarium. Visualize Rust function call graphs using LSP. Triggers on: /call-graph, call hierarchy, who calls, what calls, 调用图, 调用关系, 谁调用了, 调用了谁

Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development, covering Codebase onboarding and Incident response. It works with Rust. The repository describes itself as: A local-only journal with serious encryption. Free, open source, and never touches the internet. The licence is MIT.

When your agent uses it

Tasks that involve Codebase onboarding
Tasks that involve Incident response

Example prompts

“/rust-call-graph”

Requirements

Pre-approved tools (allowed-tools): LSP, Read, Glob

Workflow steps

3 steps, taken from the step headings in SKILL.md.

Prepare Call Hierarchy
Incoming Calls (Who calls this?)
Outgoing Calls (What does this call?)

What it can do on your machine

Read from SKILL.md and the folder at commit 75c1286. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
- LSP
- Read
- Glob
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are mermaid).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Rust Call Graph loads about 1.2k tokens when it runs. Until then it costs about 37 tokens; SKILL.md has 177 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~37
When it runs · the whole SKILL.md, loaded when a task matches: ~1.2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

name: rust-call-graph
description: Visualize Rust function call graphs using LSP. Triggers on: /call-graph, call hierarchy, who calls, what calls, 调用图, 调用关系, 谁调用了, 调用了谁
allowed-tools: LSP, Read, Glob
argument-hint: <function_name> [--depth N] [--direction in|out|both]

Rust Call Graph

Visualize function call relationships using LSP call hierarchy.

Usage

/rust-call-graph <function_name> [--depth N] [--direction in|out|both]

Options:

--depth N: How many levels to traverse (default: 3)
--direction: in (callers), out (callees), both

Examples:

/rust-call-graph process_request - Show both callers and callees
/rust-call-graph handle_error --direction in - Show only callers
/rust-call-graph main --direction out --depth 5 - Deep callee analysis

LSP Operations

1. Prepare Call Hierarchy

Get the call hierarchy item for a function.

LSP(
  operation: "prepareCallHierarchy",
  filePath: "src/handler.rs",
  line: 45,
  character: 8
)

2. Incoming Calls (Who calls this?)

LSP(
  operation: "incomingCalls",
  filePath: "src/handler.rs",
  line: 45,
  character: 8
)

3. Outgoing Calls (What does this call?)

LSP(
  operation: "outgoingCalls",
  filePath: "src/handler.rs",
  line: 45,
  character: 8
)

Analysis Insights

After generating the call graph, provide insights:

## Analysis

**Entry Points:** main, test_process_request
**Leaf Functions:** validate_header, serialize_body
**Hot Path:** main → run_server → handle_connection → process_request
**Complexity:** 12 functions, 3 levels deep

**Potential Issues:**
- `authenticate` has high fan-out (4 callees)
- `process_request` is called from 3 places (consider if this is intentional)

Common Patterns

User Says	Direction	Use Case
"Who calls X?"	incoming	Impact analysis
"What does X call?"	outgoing	Understanding implementation
"Show call graph"	both	Full picture
"Trace from main to X"	outgoing	Execution path

Questions about Rust Call Graph

What does Rust Call Graph do?

Visualize Rust function call graphs using LSP. An agent skill from fjrevoredo/mini-diarium. Rust Call Graph is an agent skill from fjrevoredo/mini-diarium. Visualize Rust function call graphs using LSP.

When should I use Rust Call Graph?

Rust Call Graph fits situations like: tasks that involve Codebase onboarding; tasks that involve Incident response.

How do I install Rust Call Graph in Claude Code?

Run `npx skills add fjrevoredo/mini-diarium --skill rust-call-graph -a claude-code`. Or copy the skill folder (.agents/skills/rust-call-graph in fjrevoredo/mini-diarium) into .claude/skills/rust-call-graph in your project. Claude Code loads it when a task matches its description.

How do I install Rust Call Graph in Codex?

Run `npx skills add fjrevoredo/mini-diarium --skill rust-call-graph -a codex`. Or copy the skill folder (.agents/skills/rust-call-graph in fjrevoredo/mini-diarium) into .agents/skills/rust-call-graph in your project. Codex loads it when a task matches its description.

Can I use Rust Call Graph in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add fjrevoredo/mini-diarium --skill rust-call-graph -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/rust-call-graph, .gemini/skills/rust-call-graph, .github/skills/rust-call-graph and .opencode/skills/rust-call-graph in your project.

What does Rust Call Graph need to run?

SKILL.md names no scripts, command-line tools or credentials: Rust Call Graph is instructions for the agent only. Its frontmatter pre-approves these tools: LSP, Read, Glob.

Does Rust Call Graph access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Rust Call Graph safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.

What licence does Rust Call Graph use?

Rust Call Graph is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Rust Call Graph use?

About 1.2k tokens (SKILL.md is roughly 4.8k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.

What are the alternatives to Rust Call Graph?

Skills that share tags, products or a category with Rust Call Graph: Deepwiki Rs (sopaco/deepwiki-rs, 3.1k stars), tilth Code Reading CLI (jahala/tilth, 352 stars), Project Structure (Eynzof/Hermes-CN-Desktop, 1.7k stars) and Codex Proxy RS Development Guide (zyycn/codex-proxy-rs, 738 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.

Who maintains Rust Call Graph?

fjrevoredo (a GitHub user) maintains it in fjrevoredo/mini-diarium, which has 308 GitHub stars. The repository holds 41 skills in this directory. The repository was last updated on October 4, 2026.
