What it does

Rails Application UI Blocks is an agent skill from pproenca/dot-skills. Compose new Rails backend pages and refactor existing Rails UI to use premium blocks from templates/application-ui. Use when requests mention ERB views, Rails partials, admin/dashboard screens, Tailwind UI assembly, or replacing custom markup with existing premium blocks while preserving behavior, accessibility, and Turbo/Stimulus hooks.

Its SKILL.md is about 800 tokens, which your agent loads only when the skill is triggered. The skill folder holds 8 other files, including scripts and reference files (for example `agents/openai.yaml`, `metadata.json` and `references/selection-playbook.md`).

It sits in Frontend & Design, covering Backend development and Accessibility. It works with Tailwind CSS. The repository describes itself as: A collection of AI agent skills following the Agent Skills open format. The licence is MIT.

When your agent uses it

  • Requests mention ERB views
  • Admin/dashboard screens
  • Tailwind UI assembly
  • Replacing custom markup with existing premium blocks while preserving behavior

Example prompts

  • “/rails-application-ui-blocks”

Requirements

  • Python 3

Workflow steps

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

  1. Start with ui.page-examples.* to anchor page structure.
  2. Choose shell from ui.application-shells.*.
  3. Add page/section headings from ui.headings.*.
  4. Add core body blocks (ui.forms.*, ui.lists.*, ui.data-display.*, ui.feedback.*).
  5. Finish with navigation and overlay details (ui.navigation.*, ui.overlays.*).

What it can do on your machine

Read from SKILL.md and the folder at commit cf93c57. 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

    Ships 1 file in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • python3

    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

Rails Application UI Blocks loads about 799 tokens when it runs, and up to ~90k if it reads all its reference files. Until then it costs about 92 tokens; SKILL.md has 314 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~92
When it runs · the whole SKILL.md, loaded when a task matches
~799
With references · SKILL.md plus every file in references/, read only if the agent opens them
~90k

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); the scripts in this folder are not scanned.

description
Compose new Rails backend pages and refactor existing Rails UI to use premium blocks from templates/application-ui. Use when requests mention ERB views, Rails partials, admin/dashboard screens, Tailwind UI assembly, or replacing custom markup with existing premium blocks while preserving behavior, accessibility, and Turbo/Stimulus hooks.

Rails Application UI Blocks

Use this skill to choose, adapt, and integrate premium UI blocks from templates/application-ui into Rails views.

Workflow

  1. Determine mode:
  • new-page for brand new features/pages
  • refactor-page for existing views/partials
  1. Identify constraints first:
  • Required interactions (Turbo Frames/Streams, Stimulus targets/actions, form semantics)
  • Accessibility constraints (labels, keyboard flow, ARIA)
  • Existing component boundaries (partials, helpers, shared layouts)
  1. Pick candidate blocks from catalog:
  • Read references/selection-playbook.md
  • Query references/template-catalog.json
  1. Integrate minimally:
  • Keep existing routes/controllers/domain logic unchanged
  • Replace markup in thin steps (shell first, then sections, then micro-components)
  1. Verify:
  • Ensure no loss of behavior, accessibility, or test coverage
  • Keep existing design tokens and class conventions where required by project standards

Selection Order

For new-page:

  1. Start with ui.page-examples.* to anchor page structure.
  2. Choose shell from ui.application-shells.*.
  3. Add page/section headings from ui.headings.*.
  4. Add core body blocks (ui.forms.*, ui.lists.*, ui.data-display.*, ui.feedback.*).
  5. Finish with navigation and overlay details (ui.navigation.*, ui.overlays.*).

For refactor-page:

  1. Preserve current information architecture and interaction contracts.
  2. Map each existing UI region to one candidate catalog block.
  3. Replace one region at a time and run relevant tests.
  4. Extract repeated markup into partials only after reuse is proven.

Guardrails

  • Do not change controllers/models/policies unless explicitly requested.
  • Do not remove data-controller, data-action, data-turbo-*, aria-*, or form field names without replacement.
  • Prefer adapting blocks to project styles over introducing conflicting visual systems.
  • Avoid block insertion that duplicates existing design-system components when native components already solve the same need.

Output Expectations

When completing a task with this skill, include:

  • Selected catalog IDs (for traceability)
  • Source template paths used
  • Any behavior/accessibility deltas introduced
  • What was intentionally not replaced and why

Resources

  • references/selection-playbook.md
    • Decision rules for what template families to check first, and when not to use them.
  • references/template-catalog.json
    • Canonical block IDs with aliases and source paths.
  • scripts/build_template_catalog.py
    • Regenerates the catalog after template updates.

Maintenance

Regenerate the catalog when files under templates/application-ui change:

bash
python3 .agents/skills/rails-application-ui-blocks/scripts/build_template_catalog.py \
  --root .
