agentviz: Skill for Claude Code

.github/skills/sync-artifacts/SKILL.md

sync-artifacts is a skill for Claude Code from jayparikh/agentviz. It costs 40 tokens per session (3,218 once invoked), scanned A, original, MIT.

A workflow for keeping five project documents and screenshot files in sync after a user-interface change. It checks which files changed, updates the affected documents, and recreates screenshots.

In plain words
What is it for?
It helps maintain README files, style guides, color-palette pages, project instructions, and screenshot sets after changing components, hooks, libraries, or other interface code.
Why use it?
User-interface changes can leave documentation, color references, instructions, and screenshots showing different versions of the product. This helps find and correct that drift before the change is committed.

Skill for Claude Code

Written for Claude Code: user-invocable in frontmatter. Also seen: mentions CLAUDE.md; mentions AGENTS.md.

This is jayparikh/agentviz's own configuration. It tells Claude Code how to work on agentviz itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything agentviz configures →

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

  • high Memory Poisoning · line 62
    Skill manipulates agent memory, state, or stored context. Memory corruption can alter personality, override safety rules, or cause unpredictable behavior.
    Fix: Protect agent memory and state from modification by untrusted content. Use read-only memory for critical instructions and validate all state changes.

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

sync-artifacts 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 1mo 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.

How it starts

The opening of the file, as written. The whole thing — 340 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTVIZ Artifact Sync

Read repository-root AGENTS.md first. You enforce its Five-artifact sync rule: review all five artifact groups for UI changes and update any drift before committing. Do not make no-op edits. Screenshot regeneration requires explicit approval; issue edits are outside this skill's authorization.

The five artifacts:

  1. README.md -- feature descriptions, architecture section, file tree
  2. docs/ui-ux-style-guide.md -- token values, patterns, rules
  3. docs/color-palette.html -- visual swatch reference for every color token (dark + light)
  4. docs/screenshots/ -- all 8 screenshot PNGs
  5. Agent guidance -- AGENTS.md for shared rules and docs/architecture.md for implementation details

CLAUDE.md and .github/copilot-instructions.md are short entry points. Keep their approval reminders and links intact; do not duplicate shared rules or architecture in them. Repository memory does not replace checked-in guidance.

Step 1: Detect What Changed

Diff the current branch against the base branch to understand what was modified:

# What branch are we on?
git rev-parse --abbrev-ref HEAD

# What files changed vs main?
git diff --name-only main

# What's the full diff?
git diff main --stat

Use git diff main for the full review, including staged and unstaged work. A three-dot comparison ending at HEAD omits uncommitted changes.

Categorize the changes:

Category Glob Artifact impact
Components src/components/**/*.jsx All five artifacts potentially
Hooks src/hooks/**/*.js README + docs/architecture.md; AGENTS.md if conventions change
Library src/lib/**/*.{js,ts} README + docs/architecture.md; AGENTS.md if conventions change
Theme tokens src/lib/theme.js Style guide + color-palette.html + screenshots
Server/routes server.js, routes/** README + docs/architecture.md; AGENTS.md if conventions change
Config package.json, vite.config.js README commands section
Tests src/__tests__/**, tests/e2e/** None (tests don't affect artifacts)
Docs only docs/**, README.md, AGENTS.md, agent entry points Self-contained, just validate consistency and links

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.
