Name: Máddu Skill Manager
Author: Skills Guide Bot

Automated summary

This skill acts as a single entry point for listing, searching, showing, creating, applying, or deleting Máddu skills — reusable SKILL.md recipes — by routing each verb to the matching `./maddu/run skill` command.

Strengths

Covers the whole skill lifecycle (list, search, show, add, apply, from-slice, delete) behind one verb parsed from `$ARGUMENTS`
Re-prints complete command output inside a fenced code block, working around the operator's collapsed bash-output view
Treats `apply` specially: the recipe is inlined into the current turn and executed step by step instead of being echoed back
Asks for confirmation before `delete` and falls back to `list` when no argument is given

Limitations

Requires the Máddu CLI (minimum version 0.18.0) and a `./maddu/run` executable in the repository
Search is plain client-side filtering over `skill list` output, with no ranking or fuzzy matching
Relies on `$ARGUMENTS` substitution specific to Claude Code slash commands, so it is not portable to other agents

When to use it

Use it when you need to browse, look up, or evolve a project's Máddu skill catalog without memorizing the underlying CLI subcommands.

When not to use it

Avoid it in repositories that do not use Máddu, or where the CLI is older than 0.18.0, since none of the invoked commands will work.

Security analysis

Caution

Quality score80/100

The skill does not contain obvious exfiltration, obfuscation, or destructive commands like `rm -rf /` or `curl | sh`. However, it relies on executing a local CLI and can delete records or follow arbitrary stored skill recipes, so it warrants caution rather than a safe rating.

Findings

•Uses bash to invoke a local executable (`./maddu/run`) even though no allowed-tools are declared.
•`delete <id>` performs a destructive operation, though the skill does instruct asking before executing.
•`apply <id>` reads and inlines arbitrary stored skill bodies and follows them step-by-step, creating a potential prompt-injection/execution-of-untrusted-instructions surface.

The operator wants to work with skills: $ARGUMENTS.

Output discipline (read carefully):

Parse $ARGUMENTS as <verb> <args>. Supported verbs:

list → ./maddu/run skill list (print all skills with one-line descriptions).
search <query> → ./maddu/run skill list + filter by query in the client; surface matches.
show <id> → ./maddu/run skill show <id>.
add / create → ./maddu/run skill add --title "..." [--when "..."] [--tags a,b] [--body "..."].
apply <id> → read the skill body via skill show, inline the recipe into the current turn, then follow it step-by-step.
from-slice <slice-id> → ./maddu/run skill from-slice --slice <id> to extract a new skill from a finished slice's hindsight.
delete <id> → ./maddu/run skill delete <id> (ask before executing — skills are non-trivial to recreate).

If $ARGUMENTS is empty, default to list.

For list, show, search, add/create, from-slice, and delete: after the bash call returns, re-print the command's complete output inside a fenced markdown code block (```) in your reply. The operator's bash-output view collapses long output behind a … +N lines (ctrl+o to expand) affordance — the only way they actually see the skill list or details is if you echo them back inside a code fence. Do not summarize, paraphrase, or omit rows.

apply is an exception: the recipe is meant to be inlined and executed step-by-step, not re-printed for the operator.

Discipline:

Skills are agent-facing recipes. They are documentation, not executables — apply means "follow the steps", not "run a script".
Tell the operator you picked /maddu-skill <verb> and surface the result; if the skill recommends a different slash command, dispatch it after one confirmation.

From the file to a first result

The download contains exactly the content displayed on this page. This copy may differ from the latest version in the source repository.

View the source and supporting files

This download contains SKILL.md only. Any scripts, references, templates and dependencies are not included. Get the required files from the source, preserving their directory structure, before continuing.

1. Download the file

Download SKILL.md

From the root of a test project, save the file as .skill-downloads/m-ddu-skill-manager-mrzxuro9/SKILL.md, or use the command below. This folder is for inspecting the skill before installation.

Command for macOS/Linux or WSL: requires a POSIX shell and curl. On Windows without WSL, use the download button and create the folder manually.

mkdir -p '.skill-downloads/m-ddu-skill-manager-mrzxuro9' && curl --fail --show-error --location 'https://skills-guides.com/api/skills/m-ddu-skill-manager-mrzxuro9/download' --output '.skill-downloads/m-ddu-skill-manager-mrzxuro9/SKILL.md.part' && mv '.skill-downloads/m-ddu-skill-manager-mrzxuro9/SKILL.md.part' '.skill-downloads/m-ddu-skill-manager-mrzxuro9/SKILL.md'

2. Check prerequisites

Read SKILL.md before using it. If it references scripts or external services, inspect them and prepare the required access in your test environment.

No recognized prerequisites section in this file. This does not mean it is self-contained: libraries, tools and access requirements may be mentioned elsewhere in the content or source repository.

The platforms on this page are catalog indications. The paths below follow tool documentation; they do not prove this skill has been run in those tools. No minimum tool version is confirmed for this listing.

3. Load the skill

After inspection, copy the complete folder into your project using one of the commands below, then open a new tool session. The command stops if a folder with the same name already exists: compare the files before replacing it.

Claude Code

test -f '.skill-downloads/m-ddu-skill-manager-mrzxuro9/SKILL.md' && test -s '.skill-downloads/m-ddu-skill-manager-mrzxuro9/SKILL.md' && mkdir -p '.claude/skills' && test ! -e '.claude/skills/maddu-skill' && cp -R '.skill-downloads/m-ddu-skill-manager-mrzxuro9' '.claude/skills/maddu-skill'

OpenSkills

OpenSkills must already be installed. The local install/read procedure is checked with OpenSkills 1.5.0, which requires Node.js ≥ 20.6.0. Catalog slugs are not resolved automatically.

Official OpenSkills installation

openskills install './.skill-downloads/m-ddu-skill-manager-mrzxuro9'

openskills read 'm-ddu-skill-manager-mrzxuro9'

Reading should display the installed file content and its base directory. It does not run the skill or install its dependencies.

For an agent that reads AGENTS.md, then sync the index. This command changes AGENTS.md: review the diff before using it.

openskills sync

Manual method or another tool: attach SKILL.md to a conversation, or open it in an agent that can read files. Include any required supporting resources. No universal folder is recognized by every tool.

4. Try a first task

Use a short, synthetic input: an API endpoint, a small document or an interface brief. In a new conversation, attach the file or give the agent its path, then adapt this request:

Read .skill-downloads/m-ddu-skill-manager-mrzxuro9/SKILL.md and apply its instructions to this example: [describe a test input]. Identify any missing files, dependencies or access. Produce the result requested by the skill without inventing data or running unreviewed scripts.

Expected result: output matching the skill instructions, or a precise list of missing prerequisites. A read confirmation alone does not validate a first use. If an external resource is unavailable, that path remains untested.
