ss-lint

ss-lint is a skill for Claude Code, Codex from bitjaru/styleseed. It costs 15 tokens per session (1,310 once invoked), scanned A, original, MIT.

A quick checker for finding common violations of a StyleSeed design system. A design system is a project’s shared rules for layout, colours, spacing, typography, and interface details.

In plain words
What is it for?
Linting StyleSeed artifacts, producing machine-readable JSON or SARIF reports, checking required coverage, and verifying that reported evidence is current.
Why use it?
It provides a repeatable scan that can reveal design problems before a screen is delivered. It also distinguishes hard validation failures from detector warnings.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

ss-lint scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Design Lint (Quick Check)

Registry-first artifact boundary

When .styleseed/project.json and .styleseed/artifacts/index.json exist, resolve the requested artifact ID first, then read only .styleseed/bundles/<artifact-id>.md and .styleseed/manifests/<artifact-id>.json. Never fall back to the global legacy bundle for a registry project. Legacy projects may use .styleseed/effective-rules.md only when no registry exists.

Canonical executable check

For a reproducible, artifact-bound scan with machine-readable output, use:

node <installed-ss-score>/scripts/styleseed-check.mjs scan \
  --project-root . --artifact <artifact-id> --format json
node <installed-ss-score>/scripts/styleseed-check.mjs scan \
  --project-root . --all --format sarif

The checker treats only contract, containment, manifest/hash, malformed-report, and required coverage failures as hard errors. Detector findings (SS001SS006) remain warnings and include a stable file, line, evidence snippet, severity, and fix. Use styleseed-check ... verify to recompute the bound evidence run; do not turn a string or stale report into a pass.

Read .styleseed/effective-rules.md and .styleseed/manifest.json; invoke /ss-resolve or $ss-resolve first when they are missing or stale. Lint detects deterministic drift; it must not flag an exact grammar/recipe/profile/adapter contract as a violation or let an arbitrary lock value create an exception.

When NOT to use

  • For deeper review of design judgment (composition, hierarchy, rhythm) → use /ss-review
  • For accessibility specifically → use /ss-a11y
  • For Nielsen UX heuristics → use /ss-audit
  • For applying refactors — this only flags violations; use /ss-review to fix

Target: $ARGUMENTS

What This Does

Fast, grep-based scan for common design violations. Runs in seconds (unlike /ss-review which is a deep manual audit). Run this after every file change.

Checks

1. Hardcoded Colors

Search for hex colors in className strings that should be semantic tokens:

grep -n '#[0-9a-fA-F]\{3,8\}' [file] | grep -v 'theme.css\|tokens\|\.json'

Violation: text-[#3C3C3C], bg-[#3182F6] Fix: text-text-primary, bg-brand

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

ss-lint is a skill published in the GitHub repository bitjaru/styleseed (943 stars, last pushed yesterday), licensed MIT. It adds 15 tokens to every session and 1,310 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
