What it does

API Assets is an agent skill from nodetool-ai/nodetool. Call nodetool.assets or nodetool.documents from a code action: find, read and save files in the user's asset library, keep a file another tool downloaded, and convert documents or extract text and tables from a PDF. Load before the first call into these namespaces.

Its SKILL.md is about 910 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: Agent-first Creative Workspace. The licence is AGPL-3.0.

When your agent uses it

Tasks that involve Document parsing

Example prompts

“/api-assets”

What it can do on your machine

Read from SKILL.md and the folder at commit 515bd28. 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 (its code samples are javascript).
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

API Assets loads about 908 tokens when it runs. Until then it costs about 69 tokens; SKILL.md has 418 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~69
When it runs · the whole SKILL.md, loaded when a task matches: ~908

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.

name: api-assets
description: Call nodetool.assets or nodetool.documents from a code action: find, read and save files in the user's asset library, keep a file another tool downloaded, and convert documents or extract text and tables from a PDF. Load before the first call into these namespaces.

nodetool.assets and nodetool.documents

An asset is a stored file in the user's library: an image, a video, audio, a document, JSON. Its locator is asset://<id> (an extension is allowed: asset://<id>.png). Reuse an asset id instead of making the same file again. The workspace is a different store: it holds the files of this run, by workspace-relative path.

nodetool.assets

Call	Does	Answers
`list({source, query, content_type, limit})`	Lists assets. `source` is `"user"` (default) or `"package"`. `content_type` is `image`, `video`, `audio`, `text` or `folder`.	Asset rows
`search(query, {content_type, limit})`	Finds assets by a name substring across every media type. `content_type` is a MIME prefix (`"image/"`). An empty query lists the newest. `limit` defaults to 25.	Handles with `asset://` uris
`images({query, limit})`	Lists image assets as handles: id, name, size, dimensions. No pixels are loaded.	Handles. Pass an id to `view_image` to see one.
`get(assetId)`	Reads one asset row. No bytes.	The row
`read(nameOrUri)`	Reads the content. Takes an `asset://` URI, an id, a `/api/storage/` key or a stored file name.	`{content}` for text, `{content_base64}` for binary
`save(name, {content \| content_base64 \| source, content_type})`	Saves a file to the library.	`{asset_id, asset_uri, url}`

save

Pass exactly one of these:

content — text, markdown or JSON.
content_base64 — binary bytes you made yourself.
source — bytes that already exist: the asset_url or /api/storage/ key that another tool returned (nodetool.web.download, run_apify_actor, a generation), an asset:// URI to copy, or an http(s) URL. The host copies them, so the bytes never pass through the guest.

Never read() a stored file to base64 to save it again. Pass it as source. Without content_type, the extension of name decides it: name an SVG logo.svg and it is stored as image/svg+xml. Show a saved image, video or audio file in the reply as ![label](asset_uri).

Show full SKILL.md (129 more words)Show less

Editing a stored image

Pass the asset to image.* (a guest global), then save the handle:

const handle = await image.resize("asset://<id>.png", { width: 1024 });
const saved = await nodetool.media.toImage(handle);
return saved.asset_uri;

nodetool.documents

File-to-file conversion with Pandoc and PDF tools. Every path is workspace-relative. Stage an asset into the workspace first with nodetool.web.download("asset://<id>", "in.pdf").

Call	Does
`convert(inputFile, outputFile, {from_format, to_format, extra_args})`	Pandoc conversion. `from_format` defaults to `markdown`, `to_format` to `pdf`. It reads markdown, docx, rst, html and more.
`extractText(pdfPath, {start_page, end_page})`	Plain text from a PDF, as `{text}`. Pages are 0-based, and `end_page: -1` is the last page.
`extractTables(pdfPath, outputJsonFile, {start_page, end_page})`	Tables from a PDF into a JSON file
`markdownToPdf(inputFile, outputFile)`	Markdown to PDF
`pdfToMarkdown(inputFile, outputFile, {start_page, end_page})`	PDF to Markdown

The output of a conversion is a workspace file. Save it to the library with nodetool.assets.save(name, {source: …}) when the user should keep it.

API Assets is an agent skill from nodetool-ai/nodetool.documents from a code action: find, read and save files in the user's asset library, keep a file another tool downloaded, and convert documents or extract text and tables from a PDF.

When should I use API Assets?

API Assets fits situations like: tasks that involve Document parsing.

How do I install API Assets in Claude Code?

Run `npx skills add nodetool-ai/nodetool --skill api-assets -a claude-code`. Or copy the skill folder (packages/system-skills/api-assets in nodetool-ai/nodetool) into .claude/skills/api-assets in your project. Claude Code loads it when a task matches its description.

How do I install API Assets in Codex?

Run `npx skills add nodetool-ai/nodetool --skill api-assets -a codex`. Or copy the skill folder (packages/system-skills/api-assets in nodetool-ai/nodetool) into .agents/skills/api-assets in your project. Codex loads it when a task matches its description.

Can I use API Assets 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 nodetool-ai/nodetool --skill api-assets -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/api-assets, .gemini/skills/api-assets, .github/skills/api-assets and .opencode/skills/api-assets in your project.

What does API Assets need to run?

SKILL.md names no scripts, command-line tools or credentials: API Assets is instructions for the agent only.

Does API Assets 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 API Assets 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. Review the folder before installing.

What licence does API Assets use?

API Assets is published under the AGPL-3.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does API Assets use?

About 908 tokens (SKILL.md is roughly 3.6k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
