What it does
Image is an agent skill from axoviq-ai/synthadoc. Extract text from images using a vision LLM
Its SKILL.md is about 540 tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including scripts (for example `scripts/__init__.py` and `scripts/main.py`).
It sits in Knowledge Management. It works with Obsidian. The repository describes itself as: Synthadoc: An open-source LLM knowledge compilation engine that turns raw documents into structured, local-first wikis. A transparent, human-readable alternative to traditional… The licence is AGPL-3.0-or-later.
When your agent uses it
- Knowledge Management work in your project
Example prompts
- “/image”
Requirements
- Python 3
What it can do on your machine
Read from SKILL.md and the folder at commit 66c9089. 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 2 files in scripts/ (Python), which the agent can run.
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 no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Image loads about 544 tokens when it runs. Until then it costs about 12 tokens; SKILL.md has 116 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.

Image Skill
Base64-encodes the image and passes it to a vision-capable LLM that extracts
all text and key information. Returns the LLM's response as result.text.
Setup
No pip dependency — the skill uses only the Python standard library plus a
LLM provider you supply at construction time. The provider can be any object
that implements the complete() interface (see below).
Standalone usage
import asyncio
from synthadoc.skills.image.scripts.main import ImageSkill
# ImageSkill REQUIRES a vision-capable provider — calling extract() without
# one raises ValueError immediately.
skill = ImageSkill(provider=my_provider)
async def main():
result = await skill.extract("/path/to/screenshot.png")
print(result.text) # extracted text from the image
print(result.metadata) # {"tokens_input": N, "tokens_output": N}
asyncio.run(main())Provider interface — any object with this async method:
async def complete(
messages: list, # list of Message objects from synthadoc.skills.base
system: str | None = None,
temperature: float = 0.0,
max_tokens: int = 4096,
) -> object # must have .text (str), .input_tokens (int), .output_tokens (int)Build the provider with any vision-capable model. Message is importable
from synthadoc.skills.base — no dependency on synthadoc.providers:
from synthadoc.skills.base import MessageSupported image formats: .png, .jpg/.jpeg, .webp, .gif, .tiff
When this skill is used

Questions about Image
What does Image do?
Extract text from images using a vision LLM. An agent skill from axoviq-ai/synthadoc. Image is an agent skill from axoviq-ai/synthadoc.
When should I use Image?
Image fits situations like: knowledge Management work in your project.
How do I install Image in Claude Code?
Run `npx skills add axoviq-ai/synthadoc --skill image -a claude-code`. Or copy the skill folder (synthadoc/skills/image in axoviq-ai/synthadoc) into .claude/skills/image in your project. Claude Code loads it when a task matches its description.
How do I install Image in Codex?
Run `npx skills add axoviq-ai/synthadoc --skill image -a codex`. Or copy the skill folder (synthadoc/skills/image in axoviq-ai/synthadoc) into .agents/skills/image in your project. Codex loads it when a task matches its description.
Can I use Image in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add axoviq-ai/synthadoc --skill image -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/image, .gemini/skills/image, .github/skills/image and .opencode/skills/image in your project.
What does Image need to run?
Going by SKILL.md and its folder, Image needs Python for the scripts in its folder. Our summary lists: Python 3.
Does Image access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Image safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
What licence does Image use?
Image is published under the AGPL-3.0-or-later licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.
How many tokens does Image use?
About 544 tokens (SKILL.md is roughly 2.2k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
What are the alternatives to Image?
Skills that share tags, products or a category with Image: Obsidian CLI (Atmosphere/atmosphere, 3.8k stars), Obsidian Canvas Boards (AgriciDaniel/claude-obsidian, 15k stars), LLM Wiki (lewislulu/llm-wiki-skill, 655 stars) and Second Brain (NicholasSpisak/second-brain, 737 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
