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

sidebar-generator 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 3d 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 — 68 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Components: Sidebar

Guides sidebar design for content sites (blogs, docs). ~80% of users focus on the left; sidebars influence flow but can hurt conversion if overused. Posts without sidebars show 3.1x higher conversion; bottom-right sticky CTAs outperform sidebars (5.62% vs 0.58% CTR).

When invoking: On first use, if helpful, open with 1-2 sentences on what this skill covers and why it matters, then provide the main output. On subsequent use or when the user asks to skip, go directly to the main output.

Initial Assessment

Check for project context first: If .claude/project-context.md or .cursor/project-context.md exists, read it for content structure and conversion goals.

Identify:

  1. Content type: Blog, docs, e-commerce
  2. Primary goal: Navigation, CTA, related content
  3. Mobile: Collapse to hamburger or hide on small screens

Best Practices

Placement

  • Left sidebar: Prime for nav; 80% of users focus left
  • Right sidebar: Secondary content, ads, related posts
  • Static vs sticky: Static for content-focused; sticky for persistent CTA (subscription, cart)

Conversion Reality

Approach Typical result
Sidebar CTA <1% opt-in for blog sidebars
In-content CTA 3x+ higher conversion
Bottom-right sticky 5.62% CTR vs 0.58% sidebar
No sidebar 3.1x higher conversion vs with sidebar

Recommendation: Prefer in-content CTAs or bottom-right sticky over sidebar CTAs. Use sidebar for nav and discovery, not primary conversion.

Widget Guidelines

  • One high-value CTA max; avoid clutter
  • Social proof: Testimonials, logos
  • Popular/related posts: Discovery, internal linking
  • Avoid: Too many ads, affiliate links; reduces trust and speed

Mobile

  • Collapse: Hamburger or off-canvas drawer
  • 57%+ mobile traffic: Responsive design non-negotiable
  • Reduce clutter: Hide or simplify sidebar on small screens

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.
