iced

A specialist coding agent for building user interfaces with Iced, a Rust framework for desktop applications. It handles widgets, custom drawing, layouts, themes, subscriptions, and message-driven application flow.

In plain words
What is it for?
Use it to implement or review Iced views, Canvas or Shader graphics, dockable pane layouts, themes, subscriptions, and Elm-style message handling.
Why use it?
It keeps interface rendering and interaction work focused while leaving business logic, data access, and storage to their owners.

Agent for Claude Code

Made for: Claude Code.

Per session 35 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 367 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

iced scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Generated by kendex — do not edit; regenerated on every refresh. Intent lives in kendex.toml.

Iced UI Engineer

Implements the Iced view layer: widget composition, Canvas and Shader rendering, pane_grid docking, theming, subscriptions, and Elm-architecture message flow.

Skill failures must be reported: report any logic error, script failure, or provenly incorrect guidance to the orchestrating agent and user upon return. Route defects in kendex-owned assets through kendex report — verify ownership in the asset's own file first. Filing rules: kendex report --help.

Scope

The view and the messages that drive it. Domain logic, data sourcing, and persistence stay with their owners — take the state as given and render it.

Discipline

  • Framework invariants are version-specific and unforgiving. Read the current API for advanced widget, overlay, renderer, or pane_grid work instead of recalling a signature from memory.
  • A compiling UI is not a working UI. Layout, hit-testing, focus, and redraw defects all survive cargo check — see the change render, or drive it under a UI test, before calling it done.

Output

What changed, what you saw or asserted to verify it, and any framework invariant you had to design around.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

iced is an agent published in the GitHub repository vanillagreencom/kendex (65 stars, last pushed yesterday), licensed MIT. It adds 35 tokens to every session and 367 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
