snek.callers

snek.callers is a command for Claude Code from 4tyone/snek. It costs 5 tokens per session (138 once invoked), scanned A, original, Apache-2.0.

A command that finds the places in a codebase where a function is called. A function is a named piece of code that performs a task and can be reused from other parts of a program.

In plain words
What is it for?
Use it to list caller files, line numbers, and surrounding code for a function, optionally limited by a file pattern.
Why use it?
It shows which parts of the program depend on a function before you change it. This helps estimate the impact of a modification and understand how code is connected.

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

snek.callers 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 7d 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.

What it actually says

Find Callers

Find all places where a function is called in the codebase.

Usage

User provides:

  • Function name
  • Optional: file pattern to limit search

Steps

  1. Search for function calls:
# Search for function call patterns
grep -rn "FUNCTION_NAME(" --include="*.EXTENSION" .
  1. Filter out the function definition itself.

  2. Display results with:

    • Caller file and line
    • Context showing the call
  3. Summarize how many places call this function.

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.
