What it does

Styleseed is an agent skill from bitjaru/styleseed. Build, improve, or inspect UI with StyleSeed. Preserves project design choices and routes setup, layout, tokens, review, rendered verification, and updates through one entry point.

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 100 other files (for example `workflows/ss-a11y/WORKFLOW.md`, `workflows/ss-audit/WORKFLOW.md` and `workflows/ss-build/WORKFLOW.md`).

It sits in Frontend & Design, covering Design systems. It works with shadcn/ui, Next.js, React and TypeScript. The repository describes itself as: Open-source design-method engine for Claude Code, Codex & Cursor. 23 agent skills for fixed design judgment, multiple grammars, semantic palettes, reference compilation, and… The licence is MIT.

When your agent uses it

  • Tasks that involve Design systems

Example prompts

  • “/styleseed”

What it can do on your machine

Read from SKILL.md and the folder at commit 257ec70. 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

    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

Styleseed loads about 1.1k tokens when it runs. Until then it costs about 48 tokens; SKILL.md has 469 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~48
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k

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.

StyleSeed

Use the user's goal to choose one first workflow below. This is the only registered core skill; the 22 workflows and their executable dependencies ship inside this directory. Read only the selected workflow, then references needed for that task.

Registry-first artifact boundary

When .styleseed/project.json and .styleseed/artifacts/index.json exist, resolve the requested artifact first. Read its .styleseed/bundles/<artifact-id>.md and manifest. A partial or invalid registry is an error; never fall back to the global legacy bundle. Legacy projects may use .styleseed/effective-rules.md only when no registry exists.

Before the first workflow in a project/task session, follow the update preflight.

Working contract

  • Preserve approved project design choices. Support expert judgment; a score is not human acceptance.
  • Resolve the current artifact first. For multiple plausible artifacts, ask one bounded clarification question.
  • Never fan out to run every workflow. Choose exactly one first workflow; it may call the required gates.
  • Honor the user's authorized scope. Audit, score, verify, and status requests do not authorize edits. Workflow metadata records the intended tool/scope boundary even though it is not host registration metadata.
  • Paths in workflow files are relative to those files. Resolve installed scripts from this skill's actual directory, never assume a particular agent folder or download a missing sibling skill.
  • In older instructions, /ss-build, $ss-build, and other ss-* names mean the corresponding internal workflow. Read workflows/<name>/WORKFLOW.md; do not invoke an unregistered skill. Users may say StyleSeed build, $styleseed build, or the old workflow name in natural language.
  • Learning is an optional extension, not part of the core install. Only for explicit learning capture, use separately installed ss-learn; if absent, report that dependency and never auto-install it.
