What it does

Snr Densification is an agent skill from hashgraph-online/awesome-codex-plugins. Use this skill when a design has too much whitespace — when the SNR pendulum has swung from cluttered all the way to sparse, sterile, or "empty-feeling," and you need to add signal density without adding noise. Trigger when reviewing a UI that "feels thin," "feels under-built," or where users complain "I'm scrolling forever to get to anything."

Its SKILL.md is about 1.9k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/density-research.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

  • A design has too much whitespace — when the SNR pendulum has swung from cluttered all the way to sparse
  • You need to add signal density without adding noise
  • Reviewing a UI that feels thin
  • Feels under-built

Example prompts

  • “empty-feeling,”
  • “feels thin,”
  • “feels under-built,”
  • “/snr-densification”

Workflow steps

5 steps, taken from the step headings in SKILL.md.

  1. Replace navigation steps with adjacent context
  2. Use compact data primitives
  3. Inline action affordances
  4. Smaller default sizes
  5. Allow user-controlled density

What it can do on your machine

Read from SKILL.md and the folder at commit 9e7b281. 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).

    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

Snr Densification loads about 1.9k tokens when it runs, and up to ~2.8k if it reads all its reference files. Until then it costs about 144 tokens; SKILL.md has 611 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~144
When it runs · the whole SKILL.md, loaded when a task matches
~1.9k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~2.8k

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 a design has *too much* whitespace — when the SNR pendulum has swung from cluttered all the way to sparse, sterile, or "empty-feeling," and you need to add signal density without adding noise. Trigger when reviewing a UI that "feels thin," "feels under-built," or where users complain "I'm scrolling forever to get to anything." Also trigger when designing power-user surfaces (admin panels, IDEs, data tools) that need higher density than consumer defaults. Sub-aspect of `signal-to-noise-ratio`; read that first if you haven't already.

Densification: adding signal without adding noise

The opposite failure mode of "noisy UI" is "sterile UI" — a design so subtractively-edited that it loses the affordances and richness users actually need. SNR is a ratio; you can improve it either by removing noise or by adding signal. This skill covers the latter.

When sterility is the problem

Symptoms:

  • Power users tell you they "miss" features that are present but tucked away.
  • The page contains 3 things on a 1440px screen and feels under-built.
  • Common workflows require navigating away and back; the current surface doesn't show enough.
  • The empty state doesn't feel empty — the populated state feels empty.
  • A/B testing shows users hesitating because there's not enough information to decide.

What signal-density looks like

Densification means more meaningful information per visible region, with the meaning still clearly readable. Done well, it looks like a Bloomberg terminal in restraint mode: many numbers, but every number labeled, ranked, and scannable.

Approaches:

1. Replace navigation steps with adjacent context

A common low-density mistake: a list view shows only names; the user clicks through to see details. Densify by showing critical detail inline.

html
<!-- Sparse: name only, click for detail -->
<li><a href="/projects/acme">Acme Q4 Refresh</a></li>

<!-- Dense: name + status + owner + due date inline -->
<li>
  <a href="/projects/acme">Acme Q4 Refresh</a>
  <span class="meta">In review · Maria · Due May 12</span>
</li>

The signal-per-line jumped 4x with no added noise.

2. Use compact data primitives

Replace large cards with rows. Replace giant icons with small ones. Replace verbose labels with shorter conventional ones.

html
<!-- Sparse: each KPI in a 200x200 card with icon and gradient -->
<div class="card-grid">
  <div class="card">…1 number…</div>
  <div class="card">…1 number…</div>
  <div class="card">…1 number…</div>
</div>

<!-- Dense: KPIs as a single row of stat blocks -->
<dl class="stat-row">
  <div><dt>Revenue</dt><dd>$48.2k <span class="delta-up">+12%</span></dd></div>
  <div><dt>Users</dt><dd>12,481 <span class="delta-up">+3%</span></dd></div>
  <div><dt>Churn</dt><dd>2.1% <span class="delta-down">-0.4%</span></dd></div>
  <div><dt>NPS</dt><dd>42</dd></div>
</dl>
3. Inline action affordances

Don't make users open a row's menu to see what they can do. Show the actions inline (icon-buttons in the row).

html
<tr>
  <td>Acme Q4 Refresh</td>
  <td>In review</td>
  <td class="actions">
    <button aria-label="Open"><EyeIcon /></button>
    <button aria-label="Comment"><MessageIcon /></button>
    <button aria-label="Archive"><ArchiveIcon /></button>
  </td>
</tr>
4. Smaller default sizes

The default shadcn/Material density is calibrated for general use. Power surfaces benefit from text-sm body, text-xs metadata, py-1.5 row padding instead of py-3. Just tune one notch denser, not five.

5. Allow user-controlled density

Offer a "Compact" mode in settings, or per-table density toggles, so users can pick their preferred ratio.

How densification differs from noise

The line between dense and noisy is whether the additional content is task-relevant.

  • Dense: more numbers, more labels, more rows, more context — all serving the user's reason for being here.
  • Noisy: more borders, more shadows, more illustrations, more decoration — none of which advance the task.

A correctly densified UI looks like more information; a noisy UI looks like more decoration around the same information.

Worked example: a sparse dashboard, densified

Before (sparse):

html
<main style="padding: 4rem; max-width: 800px; margin: 0 auto;">
  <h1>Welcome back</h1>
  <p>You have 3 things to review.</p>
  <button>Go to inbox</button>
</main>

A "welcome dashboard" of this kind feels like a placeholder. The user came to do something; they shouldn't have to click through.

After (densified):

html
<main style="padding: 1.5rem; max-width: 1200px; margin: 0 auto;">
  <header style="display: flex; justify-content: space-between; align-items: end;">
    <div>
      <h1 style="font-size: 1.5rem;">Today</h1>
      <p style="color: hsl(0 0% 45%); font-size: 0.875rem;">3 to review · 2 due this week</p>
    </div>
    <div style="display: flex; gap: 0.5rem;">
      <button>Inbox</button>
      <button class="primary">New</button>
    </div>
  </header>

  <section style="margin-top: 2rem; display: grid; gap: 1rem; grid-template-columns: 2fr 1fr;">
    <div>
      <h2 style="font-size: 1rem; margin-bottom: 0.5rem;">To review</h2>
      <ul class="dense-list">
        <li><a href="/r/1">Acme Q4 contract</a> <span class="meta">Maria · 2h</span></li>
        <li><a href="/r/2">Brand book v3</a> <span class="meta">Lin · yesterday</span></li>
        <li><a href="/r/3">2026 hiring plan</a> <span class="meta">You · 3d</span></li>
      </ul>
    </div>
    <aside>
      <h2 style="font-size: 1rem; margin-bottom: 0.5rem;">This week</h2>
      <dl class="stat-list">
        <div><dt>Open tickets</dt><dd>14</dd></div>
        <div><dt>Closed</dt><dd>52</dd></div>
        <div><dt>Avg response</dt><dd>2h 14m</dd></div>
      </dl>
    </aside>
  </section>
</main>

Same page region, ~10× the actionable signal, no added noise.

Anti-patterns

  • Densification by adding decoration. "It feels empty, let me add a hero illustration." That's the opposite move; you've added noise, not signal.
  • Densification by adding all features. Every product feature gets a tile on the dashboard regardless of relevance. That's noise too — only the user's actually-needed features should be present.
  • Density without alignment. Cramming many elements without a strict grid produces clutter, not density. Strong alignment is what allows high density to remain readable.

Heuristics

  1. Squint test in reverse. Squint at the page. Is there any dominant content? If you see only mass background and a few dots, the page is empty.
  2. The "What can I do here?" test. Land on the page cold. Within 2 seconds, can you identify 3 actions you might take? If no, density is too low.
  3. The information audit. Count the distinct pieces of useful information visible without scrolling. Compare to similar surfaces in well-designed competitors. If you're at half their count and the page feels light, densify.
  • signal-to-noise-ratio (parent).
  • snr-decoration-removal — the subtraction side of SNR; complementary to this skill.
  • hierarchy-spatial — densification needs strong spatial hierarchy or it becomes visual mush.
  • propositional-density (cognition) — closely related: meaning per mark, signal per pixel.
