What it does

Affordance False And Anti is an agent skill from hashgraph-online/awesome-codex-plugins. Use this skill when designing or fixing controls that mislead users — elements that look interactive but aren't (false affordance), or controls that need to clearly communicate "you can't do that here" (anti-affordance, like disabled states). Trigger when reviewing UIs where users tap inert elements expecting response, when designing disabled states, when picking treatments for read-only fields, or when a "decorative" element is being mistaken for a button. Sub-aspect of affordance; read that first.

Its SKILL.md is about 2.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/disabled-state-patterns.md`).

The repository describes itself as: A curated list of awesome OpenAI Codex / ChatGPT plugins, skills, and resources. The 1 Codex Marketplace. See live plugins at: https://hol.org/plugins/best-codex-plugins. The licence is Apache-2.0.

When your agent uses it

  • Fixing controls that mislead users — elements that look interactive but arent (false affordance)
  • Controls that need to clearly communicate you cant do that here (anti-affordance
  • Like disabled states)
  • Reviewing UIs where users tap inert elements expecting response

Example prompts

  • “t (false affordance), or controls that need to clearly communicate”
  • “t do that here”
  • “decorative”
  • “/affordance-false-and-anti”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Look different from enabled (lower opacity, neutral color, no fill).
  2. Not respond to hover or click as it would when enabled.
  3. Show a "no" cursor (cursor: not-allowed).
  4. Optionally explain why it's disabled — via tooltip or adjacent text.

What it can do on your machine

Read from SKILL.md and the folder at commit 3e1456a. 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 html and css).

    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

Affordance False And Anti loads about 2.1k tokens when it runs, and up to ~3k if it reads all its reference files. Until then it costs about 133 tokens; SKILL.md has 772 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~133
When it runs · the whole SKILL.md, loaded when a task matches
~2.1k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~3k

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
Use this skill when designing or fixing controls that mislead users — elements that look interactive but aren't (false affordance), or controls that need to clearly communicate "you can't do that here" (anti-affordance, like disabled states). Trigger when reviewing UIs where users tap inert elements expecting response, when designing disabled states, when picking treatments for read-only fields, or when a "decorative" element is being mistaken for a button. Sub-aspect of `affordance`; read that first.

False affordance and anti-affordance

The mirror images of standard affordance: the elements that look interactive but aren't, and the elements that are interactive but should signal "not right now." Both deserve as much design attention as standard affordance — and both are routinely neglected.

False affordance: looks interactive, isn't

A false affordance is an element whose visual treatment suggests interactivity it doesn't have. The user is led to expect an action; the action doesn't happen; trust drops.

Common sources:

  • Cards and panels styled like buttons. A bordered, rounded, slightly-elevated container holds static content. Users tap; nothing happens.
  • Hover states on non-interactive elements. A box that highlights on hover but isn't clickable. Users learn to mistrust hover signals.
  • Hyperlink-blue text that isn't a link. Some design systems use blue for emphasis without realizing users read it as link affordance.
  • Underlined non-link text. Underline is a strong link signifier; using it for emphasis or definition collides with that convention.
  • Icon-buttons next to non-interactive content. A trash icon shown next to an item the user actually can't delete.
Fixes
  • Strip interactive-looking treatments from inert content. Use neutral backgrounds, no borders, no hover changes.
  • Reserve underlines for actual links. Use bold or italics for emphasis instead.
  • If a box must look distinct, use uniform connectedness (a tinted region) rather than button-like elevation (drop shadow, border).

Anti-affordance: signaling "you can't"

Anti-affordance is the deliberate design of cues that tell the user "this is interactive in principle but unavailable to you right now." The most common case: disabled controls.

A disabled control needs to:

  1. Look different from enabled (lower opacity, neutral color, no fill).
  2. Not respond to hover or click as it would when enabled.
  3. Show a "no" cursor (cursor: not-allowed).
  4. Optionally explain why it's disabled — via tooltip or adjacent text.
html
<button class="btn" disabled
        aria-disabled="true"
        title="Add at least one item to checkout">
  Continue to checkout
</button>
css
.btn[disabled] {
  background: hsl(0 0% 92%);
  color: hsl(0 0% 50%);
  cursor: not-allowed;
  opacity: 0.7;
}
.btn[disabled]:hover {
  /* no change — this is the anti-affordance */
  background: hsl(0 0% 92%);
}
When not to disable

A common UX mistake: disabling a button silently when the user "isn't ready" (form has unfilled required field; cart is empty). The user sees a non-responsive button and doesn't know why.

Better:

  • Keep the button enabled and surface the validation error on click. The user gets a clear explanation rather than a silent block.
  • Or, if the button must be disabled, explain why alongside it (a small note, a tooltip on hover/focus, or a visible reason).
html
<button class="btn">Continue to checkout</button>
<p class="hint">Add at least one item to your cart to continue.</p>

The user can read the hint and act; the button isn't a dead end.

Read-only fields

A field that's input-shaped but not editable is a special anti-affordance case.

html
<label>Account ID
  <input type="text" value="acct_8f3c7a" readonly />
</label>
css
input[readonly] {
  background: hsl(0 0% 96%);
  color: hsl(0 0% 30%);
  cursor: text;       /* still selectable for copy */
  border: 1px solid hsl(0 0% 90%);
}

The treatment says "this is data, not a control" — neutral background, no focus outline activation, but still selectable so users can copy.

For fields that aren't currently editable but could be (e.g., locked behind a permission), the visual treatment should hint that editability exists in principle.

False affordance from animation

A subtle modern source: animating a non-interactive element. A heading that wiggles, an icon that pulses, a card that slowly tilts. These attract attention; users assume attention means interactivity.

If the animation is decoration only, audit whether it's drawing attention away from real interactive controls. If it's a callout for new content, ensure clicking does something — even if just to dismiss the callout.

Worked examples

Example 1: a card that should be clickable vs. one that shouldn't
html
<!-- Clickable: card-link wraps, hover responds -->
<a href="/projects/acme" class="card-link">
  <article class="card">...</article>
</a>

<!-- Inert: no link wrap, no hover response -->
<article class="card card--inert">
  <h3>System status</h3>
  <p>All services operational.</p>
</article>
css
.card { padding: 16px; border: 1px solid hsl(0 0% 88%); border-radius: 8px; }
.card-link { display: block; text-decoration: none; color: inherit; }
.card-link:hover .card { border-color: hsl(220 90% 60%); box-shadow: 0 4px 12px rgba(0,0,0,0.08); }

.card--inert {
  background: hsl(0 0% 98%);  /* slightly different bg signals "informational" */
  border-color: hsl(0 0% 92%);
}
.card--inert:hover {
  /* no change — anti-affordance */
}

The clickable card shifts on hover; the inert one stays still. Users learn quickly that hover-responsive cards are clickable and others aren't.

Example 2: read-only vs. disabled vs. unavailable

Three subtly different states, each with its own anti-affordance:

html
<!-- Read-only: data, never editable here -->
<label>Workspace ID
  <input value="ws_abc123" readonly />
</label>

<!-- Disabled because of state: editable when condition is met -->
<label>Email
  <input value="user@example.com" disabled aria-describedby="email-locked" />
</label>
<p id="email-locked" class="hint">Verify your email to enable changes.</p>

<!-- Unavailable due to permission: visible but not actionable -->
<label class="field-locked">
  <span>Workspace name <LockIcon aria-hidden /></span>
  <input value="Acme Inc" readonly />
  <p class="hint">Only workspace admins can change this.</p>
</label>

The user gets specific anti-affordance signals for each: read-only data is visually demoted; conditionally-disabled is enabled-looking-but-with-explanation; permission-locked has a lock icon and explanation.

Anti-patterns

  • Decorative elevation on content cards. Drop shadows that suggest "object you can interact with" on cards that are pure content. Strip the shadow.
  • Disabled-button silent dead ends. A submit button that's just disabled with no explanation. Users hunt for what's wrong.
  • Read-only fields styled identically to editable. Users tab into them, type, get confused.
  • Inert hover responses. A non-clickable element with a hover style applied "for visual interest." Users tap it, nothing happens, trust drops.

Heuristics

  1. The "I tapped, nothing happened" audit. Watch users. Each unproductive tap is a false-affordance failure or an anti-affordance failure (disabled with no explanation).
  2. The hover-style audit. Every element with a hover state should be interactive. If you have hover styles on non-interactive elements, strip them.
  3. The disabled-with-context check. Every disabled control on every page should answer "why?" — via tooltip, adjacent text, or context.
  • affordance (parent).
  • affordance-signifiers — the standard case of making affordance visible.
  • feedback-loop — disabled controls should still give some feedback (cursor change at minimum).
  • accessibility-understandable (process) — disabled states must be programmatically conveyed (disabled attribute, aria-disabled).
