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 | $0.00013 | $0.00286 |
| Opus 5 | $0.00006 | $0.00143 |
| Sonnet 5 | $0.00003 | $0.00057 |
| Haiku 4.5 | $0.00001 | $0.00029 |
Grade A, and why
julia-activate 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 3d 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 Activate
Activate a Julia project or environment for the current session.
Arguments
path- Path to project directory, "." for current directory, or named environment like "@v1.10"
Instructions
-
Parse the user's argument to determine the path:
- If no argument or ".", activate the current working directory
- If a path is given, use that path
- If starts with "@", it's a named environment
-
Call
activatewith the path -
After activation, offer to run
pkg(action="instantiate")to install dependencies if the project has a Project.toml
Examples
/julia:julia-activate .
/julia:julia-activate /path/to/MyProject
/julia:julia-activate @v1.10
Notes
- Activating a project changes where packages are installed/loaded from
- Use
pkg(action="instantiate")after activation to install dependencies - The activated environment persists across
resetcalls - Use
infoto see the currently active project
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-activate is a skill published in the GitHub repository samtalki/AgentREPL.jl (6 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 13 tokens to every session and 286 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.
