julia-reset

julia-reset is a skill for Claude Code from samtalki/AgentREPL.jl. It costs 15 tokens per session (309 once invoked), scanned A, original, Apache-2.0.

A Julia tool that completely restarts the background worker process used to run Julia code. It clears the current variables, functions, and loaded packages, then restores the active project.

In plain words
What is it for?
Use it to reset a Julia session, apply structure changes in older Julia versions, stop stuck computations, and reload the project or Revise.jl when available.
Why use it?
It provides a clean start when a Julia session is stuck, corrupted, or cannot accept changes such as a redefined data structure. It also avoids having to close and reopen the whole development setup.

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

julia-reset 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 1mo 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

Julia Reset

Kill the Julia worker process and spawn a fresh one (hard reset).

What This Does

This is a hard reset that:

  • Kills the worker process entirely
  • Spawns a fresh Julia worker
  • Clears all variables, functions, and loaded packages
  • Enables type/struct redefinitions (necessary in Julia < 1.12)
  • Re-activates the previously activated project
  • Reloads Revise.jl if available

Instructions

  1. If the user provides a session name argument, pass it as the session parameter
  2. Call the reset MCP tool
  3. Report the old and new worker IDs to the user
  4. Remind the user that packages need to be reloaded with using

When to Use

  • You need to redefine a struct layout (Julia < 1.12)
  • The session is in a bad/corrupted state
  • You want a completely clean slate
  • Code is stuck/hanging (infinite loop, long computation)

When NOT to Use

  • For function/method changes: use revise(action="revise") instead — it preserves session state
  • For package issues: try pkg(action="resolve") first
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.

julia-reset is a skill published in the GitHub repository samtalki/AgentREPL.jl (7 stars, last pushed 4mo ago), licensed Apache-2.0. It adds 15 tokens to every session and 309 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-08-31.
