What it does
Setting Profile Images is an agent skill from letta-ai/skills. 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.
Its SKILL.md is about 640 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including scripts (for example `scripts/set_profile_image.py`).
It works with Letta. The repository describes itself as: A shared repository for skills. Intended to be used with Letta Code, Claude Code, Codex CLI, and other agents that support skills.
When your agent uses it
- The user asks to add
- Fix an agent avatar
- Profile picture
- Desktop agent photo
Example prompts
- “/setting-profile-images”
Requirements
- Python 3
- A credential in LETTA_API_KEY
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Obtain an image
- Convert/crop it to a square PNG using scripts/set_profile_image.py.
- Commit the resulting profile.png to the target agent's memory repo.
- Verify via the profile-picture endpoint when LETTA_BASE_URL and LETTA_API_KEY are available.
- Tell the user to reload/reopen the agent profile in Desktop if the old image is cached.
What it can do on your machine
Read from SKILL.md and the folder at commit 6785511. 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:
python3git
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
LETTA_API_KEY
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Setting Profile Images loads about 640 tokens when it runs. Until then it costs about 65 tokens; SKILL.md has 208 words of instructions outside code blocks.
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.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 208 words (~640 tokens).
