Agent Skill for Maple

OptimusMaplePrime — Wed, 29 Jul 2026 18:36:34 Z

Has anyone developed an Agent Skill for Maple compliant with the Agent Skills Specification?

I frequently use Claude Code to create and edit Maple Documents. It does fine alone, but I found adding a script to do a syntax check eliminated a lot of content errors. I also presume some instructions on how it should read the Maple documentation will improve its reliability. Before I go about writing my own Skill against the specification, I just want to check if there is already one in use within the community.

Simplifications and substitutions

Ronan — Wed, 29 Jul 2026 16:37:44 Z

I am trying to follow a series of substitutions used in a paper. I have given some examples of the substitutions. But I am having difficulty getting them to work. I know if all else fails I can manually recreate an expression with the substitution variables and then check backwards using eval(f,vals).
Would appreciate any insight on substitution techniques here.

MapleV for emacs 30.2

Mac Dude — Wed, 29 Jul 2026 14:09:15 Z

I am a long-time user of Joe Riel's maplev mode in emacs. Upgraded emacs to version 30.2 and now it does not work anymore because of difficulties with something called abbrevlist. This is on MacOS. I am already on the last version of maplev.

Anyone have an idea what is going on and what to do? Somehow for me referencing a username no longer is possible (I get a blocking box with a spinner upon entering the at sign) so I can't create a notification for Joe.

TIA,

Mac Dude.

Recalcitrant differential equation

Alfred_F — Wed, 29 Jul 2026 09:10:23 Z

In the attached file, I'd like to solve an ODE as an exercise. Only the "series" option yielded a solution. How can the length of the result series be controlled? Is there a package that leads to a "closed" solution – even using well-known transcendental functions?

How to improve printing of procedures with units

C_R — Mon, 27 Jul 2026 09:38:34 Z

This piecewise function with units

q := r -> piecewise(0 <= r and r < 0.1*Unit('mm'), 5*Unit(('kW')/'m'^2));

returns this output

Is it possible to get the output printed without ticks and the units in roman?

How is a cyclic command sequence programmed?

Alfred_F — Sat, 25 Jul 2026 15:18:20 Z

In the attached file, I would like to calculate the expressions for the function f(n,x) using a recursion for a given index range, e.g., n=3..15. I would appreciate any advice on this.
