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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00048 | $0.01284 |
| Opus 5 | $0.00024 | $0.00642 |
| Sonnet 5 | $0.00010 | $0.00257 |
| Haiku 4.5 | $0.00005 | $0.00128 |
Grade A, and why
rust-call-graph 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 6d 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.
How it starts
The opening of the file, as written. The whole thing — 207 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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
)

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.

rust-call-graph is a skill published in the GitHub repository moeru-ai/auv (25 stars, last pushed 2d ago), licensed Apache-2.0. It adds 48 tokens to every session and 1,284 once invoked, about $0.0002 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.
