What is julia-revise?

A Julia development workflow for loading source-code changes into an existing session with Revise.jl. Julia is a programming language, and Revise.jl can update tracked code without restarting the session.

Use it to track files, include them with change tracking, reload edits, inspect tracked files, and continue working in the same Julia session.

It avoids losing variables, data, and loaded packages every time a function changes during interactive development. It also helps distinguish changes that Revise can load from cases that require a full reset.

Install

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.

Any agent

npx skills add samtalki/AgentREPL.jl --skill julia-revise

Clone the repo

git clone --depth 1 https://github.com/samtalki/AgentREPL.jl

Made for: Claude Code.

Or install julia, the plugin that ships this one along with the rest of its 10 skills, 1 hook, 1 MCP server.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00020	$0.00541
Opus 5	$0.00010	$0.00270
Sonnet 5	$0.00004	$0.00108
Haiku 4.5	$0.00002	$0.00054

Security

Grade A, and why

julia-revise 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

Julia Revise (Hot-Reload)

Hot-reload Julia code changes using Revise.jl — the key to maximizing REPL session lifespan.

Arguments

No argument: triggers revise(action="revise") to pick up all file changes
track <path>: starts tracking a file with Revise
includet <path>: includes a file with Revise tracking
status: shows what Revise is tracking

Instructions

Parse the user's argument to determine the action and optional path
Call revise with the appropriate action and path parameters
If Revise is not available, offer to install it:
- pkg(action="add", packages="Revise")
- Then reset to reload (Revise loads automatically on worker startup)

Revise Workflow

Revise.jl enables iterative development without losing session state:

Edit Julia source files (using Claude's Edit/Write tools)
Call revise(action="revise") to pick up changes
Continue working — all variables, data, and packages are preserved

This eliminates the most common reason for using reset.

When to Use Revise vs Reset

Situation	Use Revise	Use Reset
Changed function body	Yes	No
Added new function	Yes	No
Modified method signature	Yes	No
Changed struct layout (Julia < 1.12)	No	Yes
Corrupted session state	No	Yes
Want clean slate	No	Yes
Changed const value	Sometimes	If needed

Tips

Revise.jl is auto-loaded on worker startup if installed in the environment
After pkg(action="develop", packages="./MyPkg"), Revise automatically tracks the package source
Use includet("file.jl") (via eval) instead of include("file.jl") for standalone scripts — it enables hot-reloading
Call revise(action="status") to see what files and packages Revise is watching

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-revise is a skill published in the GitHub repository samtalki/AgentREPL.jl (6 stars, last pushed 3mo ago), licensed Apache-2.0. It adds 20 tokens to every session and 541 once invoked, about $0.0001 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 2026-08-31.
