  • Markdown instructions

    A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.

  • Works with any LLM

    AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.

  • 1 bundled files

    Scripts, templates, and references the model can read while it works. Files are read-only and never executed.

  • Open source

    Published by letta-ai on GitHub. Read the source before you install it.

Installation

Install the Setting Profile Images AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

1

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

  1. Open the app and go to Plugins → Skills.
  2. Choose "Install from GitHub".
  3. Paste the skill folder URL below and confirm.
  4. Enable the skill in any chat where you want it available.
Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.
2

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills
git clone --depth 1 https://github.com/letta-ai/skills.git /tmp/skills
mkdir -p .claude/skills
cp -r /tmp/skills/letta/setting-profile-images .claude/skills/setting-profile-images
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Setting Profile Images in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Setting Profile Images on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Setting Profile Images is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

  • Loaded only when it is needed

    The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.

  • Switch models mid-chat

    Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

Setting Profile Images

Key fact

Letta Desktop displays an agent profile image from the agent memory repository at:

text
$MEMORY_DIR/profile.png

The Desktop/local backend API reads the same file via:

text
GET /v1/agents/:agent_id/profile-picture

For local Desktop agents, do not PATCH arbitrary agent metadata for the avatar. Write profile.png into MemFS and commit it.

Workflow

  1. Obtain an image:
    • Use a user-provided image path, or
    • Generate/create an avatar image with another image/art skill, then save it locally.
  2. Convert/crop it to a square PNG using scripts/set_profile_image.py.
  3. Commit the resulting profile.png to the target agent's memory repo.
  4. Verify via the profile-picture endpoint when LETTA_BASE_URL and LETTA_API_KEY are available.
  5. Tell the user to reload/reopen the agent profile in Desktop if the old image is cached.

Current agent quick start

Locate this skill's script if needed:

bash
SCRIPT=$(find ~/letta/skills ~/.letta/skills -path '*/setting-profile-images/scripts/set_profile_image.py' -print -quit)

Set the current agent's profile image:

bash
python3 "$SCRIPT" /path/to/avatar.png

The script uses, in order:

  • --memory-dir, if passed
  • $MEMORY_DIR
  • $LETTA_MEMORY_DIR
  • ~/.letta/lc-local-backend/memfs/$AGENT_ID/memory

Other local agent

bash
python3 "$SCRIPT" /path/to/avatar.png \
  --agent-id agent-local-... \
  --local-backend-dir ~/.letta/lc-local-backend

Useful options

bash
python3 "$SCRIPT" /path/to/avatar.jpg --size 512
python3 "$SCRIPT" /path/to/avatar.jpg --no-commit
python3 "$SCRIPT" /path/to/avatar.jpg --verify
  • --size controls the square output size in pixels. Use 512 unless there is a reason not to.
  • --no-commit writes the file but leaves the memory repo uncommitted.
  • --verify calls /v1/agents/:agent_id/profile-picture after writing, when API env vars are present.

Manual fallback

If the script is unavailable:

bash
cp /path/to/avatar.png "$MEMORY_DIR/profile.png"
git -C "$MEMORY_DIR" add profile.png
git -C "$MEMORY_DIR" commit --author="$AGENT_NAME <$AGENT_ID@letta.com>" -m 'Add agent profile image'

Make sure the image is a reasonably sized square PNG before copying.

Bundled files

The model reads these on demand while the skill is loaded. They are exposed as readable files and are never executed.

Frequently asked questions

What does the Setting Profile Images AI skill do?

Sets Letta Desktop and Letta Code agent profile images by writing profile.png into an agent MemFS repository. Use when the user asks to add, change, generate, or fix an agent avatar, profile picture, profile image, or Desktop agent photo.

Why use Setting Profile Images on TypingMind?

Because you install it once and use it with any model. Setting Profile Images is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Setting Profile Images in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/letta-ai/skills/tree/main/letta/setting-profile-images. TypingMind reads its SKILL.md and bundles its files and installs it as a skill you can enable per chat.

Which AI models can use Setting Profile Images?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Setting Profile Images?

As many as you like. As long as a model supports skills, you can use Setting Profile Images with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Setting Profile Images AI skill free?

It is published on GitHub by letta-ai. Check the repository for licensing terms. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
