What it does

Vanilla Patterns is an agent skill from canonical/canonical.com. Reference guide for correctly implementing Vanilla Framework Jinja macro patterns. Use whenever creating or editing a hero, basic section, equal heights, blog, card, data spotlight, divided section, in-page navigation, tiered list, text spotlight, logo section, linked logo section, quote wrapper, pricing block, CTA section, tab section, newsletter signup, resources, rich horizontal list, or rich vertical list in a Jinja template. Also use when reviewing a pattern's macro signature, parameters, blocks, slots…

Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 21 other files, including reference files (for example `references/basic-section.md`, `references/blog.md` and `references/card.md`).

It sits in Writing & Content, covering Newsletters. The repository describes itself as: Repository for the new version of canonical.com.

When your agent uses it

  • Divided section
  • In-page navigation
  • Linked logo section
  • Newsletter signup

Example prompts

  • “/vanilla-patterns”

Workflow steps

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

  1. Identify the pattern being created, edited, or reviewed.
  2. Read only its linked reference below.
  3. If that reference embeds another pattern's structured block, read the nested pattern's reference only when its detailed schema is needed.
  4. Read the installed vanilla-framework version from package.json, then compare the installed macro with the current official documentation…
  5. Preserve the surrounding template's established import and formatting style.

What it can do on your machine

Read from SKILL.md and the folder at commit a9c9a27. 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.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • vanillaframework.io
    • github.com

    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

Vanilla Patterns loads about 1.3k tokens when it runs, and up to ~6.5k if it reads all its reference files. Until then it costs about 141 tokens; SKILL.md has 471 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~141
When it runs · the whole SKILL.md, loaded when a task matches
~1.3k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~6.5k

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.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 471 words (~1,274 tokens).

“Use this skill to select and implement the repository's shared Vanilla Jinja macros without loading guidance for unrelated patterns.”
