# Icon Generator

## Freshness
Last updated: `2026-07-14`.

If the current date is more than 7 days after the last updated date, reinstall this skill from skills.sh or ClawHub before relying on endpoints, schemas, setup steps, or examples.

## What This Tool Does
Build crisp icons, sprites, and game-ready textures at any size from 1 to 4096 pixels. Compose them from rectangles, circles, lines, polygons, arcs, text, and transforms — and get a transparent or solid-background PNG ready to drop into apps, marketplaces, or game projects. A dedicated pixel-art mode produces hard-edged, integer-snapped output for 16×16, 32×32, and 64×64 sprites suitable for Minecraft mod textures, retro UI, deterministic favicons, and other small-format game assets. Every render is deterministic — the same inputs always produce the same PNG — and the returned file_id plugs directly into any downstream tool that accepts an image file_id.

## Product Instructions
### Icon Generator

Render deterministic PNG icons, sprites, textures, and small illustrations from
bounded drawing instructions. Generation creates one tenant-owned File Manager
record retained for 3 days.

#### Action: `generate`

Required:

- `idempotency_key`: UUID. Reuse it only for an exact retry.
- `instructions`: 1-256 drawing operations, including at least one drawable
  operation, with at most 8192 coordinate pairs across the request.

Optional:

- `width`, `height`: 1-4096 pixels, default 2048. Both are limited to 256 when
  `pixel_art_mode` is true.
- `pixel_art_mode`: disables anti-aliasing, snaps coordinates to integer pixels,
  and rejects text instructions.
- `continue_on_error`: records fixed, redacted renderer warnings and continues
  after a rendering failure only when at least one drawable operation succeeds.
  All skipped operations produce one aggregate operator warning. Structural
  validation errors always reject the request.
- `background_color`: `#RRGGBB`, `#RRGGBBAA`, `transparent`, or a documented
  named color; default `#FFFFFF`.

An idempotent retry returns the original `file_id` with a newly generated,
tenant-scoped signed URL. A reused UUID with a different payload is rejected. An
ambiguous storage outcome is never repeated automatically.

#### Drawing operations

Every instruction requires canonical `shape_type`. Unexpected fields are
rejected, including fields that belong to another shape.
Every drawable instruction must have paint whose effective alpha is non-zero;
`transparent`, `#RRGGBB00`, and `opacity: 0` are not usable drawing paint.

- `rectangle`: `x`, `y`, `width`, `height`; requires `fill` or `stroke`.
- `rounded_rectangle`: rectangle fields plus `radius`; requires paint.
- `circle`: center `x`, `y`, `radius`; requires paint.
- `ellipse`: center `x`, `y`, `radius_x`, `radius_y`; requires paint.
- `line`: at least two `points`; accepts `stroke`, `stroke_width`, `opacity`,
  and `anti_alias`.
- `polygon`: at least three `points`; requires `fill` or `stroke`.
- `arc`: center/radius plus `start_angle`, `end_angle`, and stroke fields.
- `text`: requires `text`; accepts `x`, `y`, `fill`, `font_size`,
  `font_family`, `font_weight` (`normal` or `bold`), and `text_align`. The font
  family must be installed on the renderer.
- `path`: requires an SVG path string and `fill` or `stroke`. Commands M, L, H,
  V, C, S, Q, T, A, and Z are supported.
- `save_state`, `restore_state`: bracket canvas state. Every save must have a
  matching restore and a restore cannot occur first.
- `translate`: requires `x` or `y`.
- `rotate`: requires `rotate`; optional `x` and `y` select its center.
- `scale`: requires non-zero `scale_x` or `scale_y` in the range -100 to 100.

Coordinates are limited to -16384 through 16384. Paths are capped at 100,000
characters and 8192 parsed segments; every parsed path coordinate uses the same
finite coordinate bound. Each line/polygon accepts at most 2048 distinct-capable
point pairs. Colors are strictly parsed. `opacity` is a 0-1 multiplier on the
original alpha channel. Pixel-art geometry that collapses after integer snapping
is rejected instead of producing a blank operation.

#### Examples

Smooth 256x256 icon:

```json
{"action":"generate","idempotency_key":"6ace54fe-f93d-4ba2-bfb8-98d4995120d8","width":256,"height":256,"background_color":"transparent","instructions":[{"shape_type":"circle","x":128,"y":128,"radius":100,"fill":"#2563EB"},{"shape_type":"path","path":"M78 130 L112 164 L180 88","stroke":"#FFFFFF","stroke_width":18}]}
```

16x16 pixel-art sprite:

```json
{"action":"generate","idempotency_key":"f7036c19-9013-42ea-8c88-6b0ff305455e","width":16,"height":16,"pixel_art_mode":true,"background_color":"transparent","instructions":[{"shape_type":"rectangle","x":7,"y":1,"width":2,"height":9,"fill":"#C0C0C0"},{"shape_type":"rectangle","x":5,"y":9,"width":6,"height":1,"fill":"#8B4513"},{"shape_type":"rectangle","x":7,"y":10,"width":2,"height":5,"fill":"#8B4513"}]}
```

#### Response and retention

The response includes `file_id`, `filename`, `signed_url`,
`signed_url_expires_in` (`15 minutes`), `size_bytes`, `expiration_date`,
`icon_details`, and `warnings`. The backing file expires after 3 days; the
signed URL is intentionally much shorter lived and is not persisted in the
idempotency record. An idempotent replay adds `idempotent_replay: true`.

Stable idempotency/storage failures include `IDEMPOTENCY_KEY_REUSED`,
`IDEMPOTENCY_IN_PROGRESS`, `IDEMPOTENCY_OUTCOME_UNKNOWN`, and
`IDEMPOTENCY_STORE_UNAVAILABLE`. Rendering/storage failures use
`ICON_RENDER_INSTRUCTION_INVALID`, `ICON_RENDER_FAILED`,
`ICON_STORAGE_UPLOAD_FAILED`, and `ICON_STORAGE_REPLAY_FAILED`. If the outcome
is unknown, inspect File Manager before deciding whether to submit a new UUID.

## Actions And Schema
Complete generated action schema: `./schema.md`.
Supported action count: `1`.
x402 availability: not enabled for this product.

- `generate` (action slug: `generate`): Render a deterministic PNG and store it for 3 days. This creates one file; idempotent retries return the same file with a fresh 15-minute tenant-scoped signed URL. Price: `5` credits. Parameters: `background_color`, `continue_on_error`, `height`, `idempotency_key`, `instructions`, `pixel_art_mode`, `width`.

## Live Schema And Examples
Use the compact schema above for ordinary calls. Before a new production integration, or whenever parameters, enum values, nested objects, outputs, or examples are unclear, fetch live details first.

- Exact schema: call `agentpmt-tool-search-and-execution` with `action: "get_schema"`, and `tool_id: "product-icon-generator"`.
- Detailed examples: call `agentpmt-tool-search-and-execution` with `action: "get_instructions"` and `tool_id: "product-icon-generator"`, or call this product with `action: "get_instructions"` when the product tool is already selected.
- Treat returned live schema and instructions as more specific than this generated summary.

MCP schema lookup through the main AgentPMT MCP server:

```json

Use the setup skill for the account connection details before making REST calls.

## Response Handling
- Treat the returned JSON as the source of truth for this tool call.
- If the response includes warnings or correction targets, apply them before retrying.
- If the response includes a `passed` or success-style boolean, use it as the workflow gate.
- If validation fails or the response shape is unclear, call `get_schema` or `get_instructions` before retrying.
- If `generate` fails, preserve the request parameters and retry only after fixing schema, auth, or payment errors.

## Security
- Do not place account secrets, wallet private keys, mnemonics, signatures, or payment headers in prompts or logs.
- Keep tool inputs scoped to the minimum content needed for the task.
- Use the setup skills for credential handling; this product skill only defines product-specific behavior.
