What it does

Skill Creator is an agent skill from MemTensor/memmy-agent. Create, edit, improve, tidy, review, audit, or restructure memmy-agent skills and SKILL.md files.

Its SKILL.md is about 940 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including scripts (for example `scripts/quick-validate.py`).

It sits in Agent Workflows, covering Skill authoring. It works with OpenAI. The repository describes itself as: 🍙 A personal AI agent & local memory hub for all AI agents, gives every AI one shared, fully controlled memory and persistent context — all AI remember the same you. Now… The licence is MIT.

When your agent uses it

Tasks that involve Skill authoring

Example prompts

“/skill-creator”

Requirements

Python 3
A credential in GITHUB_TOKEN

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

Clarify the real use cases and triggering phrases.
Pick a short hyphen-case name.
Create /skills//SKILL.md.
Add only the resource directories that are actually needed.
Run the validator.
Test any scripts by executing them on realistic inputs.

What it can do on your machine

Read from SKILL.md and the folder at commit ee0ed02. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 1 file in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
- python3
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
- GITHUB_TOKEN
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Skill Creator loads about 944 tokens when it runs. Until then it costs about 28 tokens; SKILL.md has 447 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~28
When it runs · the whole SKILL.md, loaded when a task matches: ~944

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

Skill Creator

Use this skill when creating or maintaining a memmy-agent skill.

Core Principles

Keep the skill small enough to load quickly. Put only the essential workflow in SKILL.md; move detailed reference material into references/, reusable deterministic code into scripts/, and output assets into assets/.

Write for another agent that is already capable. Include the procedural details, constraints, commands, schemas, and examples that would be annoying or risky to rediscover.

Skill Shape

A skill is a directory with one required file and optional resources:

text

skill-name/
├── SKILL.md
├── scripts/
├── references/
└── assets/

SKILL.md must contain YAML frontmatter followed by Markdown instructions.

Required frontmatter:

yaml

---
name: my-skill
description: Do the specific workflow. Use when the agent needs to handle concrete trigger cases.
---

Supported memmy-agent frontmatter fields:

name: lowercase letters, digits, and hyphens only.
description: the trigger text that decides when the skill is useful.
metadata: optional memmy-agent runtime metadata.
always: optional boolean for skills that should always load.
license: optional license label.
allowed-tools: optional tool guidance for consumers.

Use only metadata.memmy for runtime metadata:

yaml

metadata:
  memmy:
    always: true
    manualOnly: false
    requires:
      bins: ["gh"]
      env: ["GITHUB_TOKEN"]

Set metadata.memmy.manualOnly: true for a Skill that must stay out of the normal Skill index and load only when the current task explicitly references $skill-name. Do not combine it with startup initialization.

Creation Workflow

Clarify the real use cases and triggering phrases.
Pick a short hyphen-case name.
Create <workspace>/skills/<skill-name>/SKILL.md.
Add only the resource directories that are actually needed.
Run the validator.
Test any scripts by executing them on realistic inputs.

Create files directly. There is no required init scaffold command for memmy-agent skills.

Show full SKILL.md (211 more words)Show less

Writing SKILL.md

Put all trigger information in the frontmatter description. The body is loaded only after the skill triggers, so a "when to use this skill" section in the body is too late to help discovery.

Use the body for:

A short operating procedure.
Commands that should be run exactly.
References to bundled files and when to read them.
Constraints that prevent common mistakes.

Avoid:

README, changelog, installation guide, or process notes inside the skill root.
Placeholder text such as TODO, "fill me in", or example-only resource files.
Duplicating long reference material in both SKILL.md and references/.

Resource Guidance

Use scripts/ for repeatable operations where deterministic behavior matters. Prefer Python, shell, or other scripts that can run through an explicit interpreter command.

Use references/ for large instructions, schemas, API notes, policies, or examples that should be read only when relevant.

Use assets/ for templates, images, fonts, sample documents, or other files that are consumed as output resources rather than read into context.

Validation

Run the bundled quick validator before considering a skill ready:

bash

python3 {baseDir}/scripts/quick-validate.py <skill-dir>

Replace {baseDir} with the path to this skill-creator directory. The validator checks the required frontmatter, memmy-agent metadata namespace, name format, placeholder descriptions, and root file organization.

If validation fails, fix the reported issue and run the command again.

Files

SKILL.md and 1 other file (scripts) in App/memmy-agent/src/skills/skill-creator of MemTensor/memmy-agent.
