What it does
API Sketches is an agent skill from nodetool-ai/nodetool. Call nodetool.sketches from a code action: create a sketch (layered image document), read it, add, arrange and restyle layers, place images on layers, resize the canvas, validate it, and manage its versions. Load before the first call into nodetool.sketches.
Its SKILL.md is about 860 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 Media & Creative. The repository describes itself as: Agent-first Creative Workspace. The licence is AGPL-3.0.
When your agent uses it
- Media & Creative work in your project
Example prompts
- “/api-sketches”
What it can do on your machine
Read from SKILL.md and the folder at commit 58765d3. 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 Sketches loads about 858 tokens when it runs. Until then it costs about 68 tokens; SKILL.md has 353 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); files beside SKILL.md are not scanned.

- Call nodetool.sketches from a code action: create a sketch (layered image document), read it, add, arrange and restyle layers, place images on layers, resize the canvas, validate it, and manage its versions. Load before the first call into nodetool.sketches.
nodetool.sketches
A sketch is an image document: a canvas, a stack of layers, and the bindings
that say where the picture of a layer comes from. How to compose one is
nodetool-sketch. This is the call reference. One finished image with no
layers to keep is nodetool.media.generateImage, not a sketch.
| Call | Does | Answers |
|---|---|---|
list({query, limit}) | Lists sketches, newest first. | Rows with id, name and canvas size |
create(name, {width, height, background_color, project_id, id}) | Creates a blank canvas. The defaults are 1024×1024 on #ffffff. An existing id you own is returned instead of a copy. | {image_document_id, …} |
get(id) | Reads the document: canvas, background, layers, bindings. Layer bitmaps stay opaque. | The document |
edit(id, ops) | Applies layer ops in order and saves. An open editor picks the change up live. | The result of each op |
validate(idOrDocument) | Checks the structure without a render. | {ok, issues} |
versions(id, {save_type, limit}), getVersion(id, n) | Lists and reads whole-document snapshots. | Version rows, newest first |
snapshot(id, {name}) | Saves a manual version. | The version number |
restore(id, n) | Rolls back. The state it replaces is snapshotted first. | The findings of the validation after the restore |
deleteVersion(id, n) | Deletes one snapshot. This cannot be undone. | — |

imageis an asset id, anasset://locator, adata:URL or an http(s) URL. The layer points at it and the editor draws it at its natural size from the top-left of{x, y, width, height}, which defaults to the whole canvas. Pass the dimensions of the image when you know them.use_caseisproduct,portrait,key-art,social,logo,conceptortexture, and it also sets the canvas size.- Pixels are never read or written here. Painting and generation happen in an open editor or a workflow run.
