What it does

Image Reading is an agent skill from deathbyknowledge/gsv. Read and analyze images on GSV or connected targets with img2txt. Use for captions, visual questions, OCR, structured extraction, object pointing or detection, and screenshots or image files stored on another target.

Its SKILL.md is about 340 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Documents & Office, covering Document parsing. The repository describes itself as: Personal AI computer / distributed OS across all your devices. The licence is MIT.

When your agent uses it

  • Visual questions
  • Structured extraction
  • Object pointing
  • Image files stored on another target

Example prompts

  • “/image-reading”

What it can do on your machine

Read from SKILL.md and the folder at commit 684cdc8. 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

    No scripts in the folder and no shell commands in SKILL.md.

    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 Reading loads about 343 tokens when it runs. Until then it costs about 58 tokens; SKILL.md has 156 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~58
When it runs · the whole SKILL.md, loaded when a task matches
~343

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); files beside SKILL.md are not scanned.

description
Read and analyze images on GSV or connected targets with img2txt. Use for captions, visual questions, OCR, structured extraction, object pointing or detection, and screenshots or image files stored on another target.

Read Images

Run img2txt from the gsv target. Use man img2txt for current syntax.

Choose the mode based on the task:

  • caption: Describe the image. Use --length short|normal|long.
  • query: Answer a specific visual question. Requires --prompt.
  • ocr: Extract text. Optionally use --prompt to narrow the extraction.
  • point: Return normalized coordinates for instances of an object. Requires --target.
  • detect: Return normalized bounding boxes for instances of an object. Requires --target.

Pass images directly using a local path, gsv:/path, target:/path, or [target-with-colons]:/path. Target images stream directly and do not need to be copied into GSV first.

For query and ocr, use --response-format for JSON, XML, Markdown, or CSV. Use --schema with JSON when the result must have a specific structure.

Use --reasoning --json when query reasoning or grounding is useful. Use --stream only for unstructured caption, query, or OCR text; it cannot be combined with JSON envelopes, reasoning, or structured output.

point and detect produce JSON by default.
