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.

Fable 5.1 $0.00054 $0.01125

Security

Grade A, and why

30x-seo-content-brief 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.

Content Brief Generator

SERP Analysis → Content Brief → Outrank Competition

Goal

Not rewriting competitors, but analyzing them to write better content.

Wrong Approach Right Approach
Rewrite Top 10 articles Analyze Top 10 intent
Copy content structure Find gaps (what they missed)
Merge competitor content Outperform (add original data/cases)

Workflow

Step 1: SERP Scraping

Input: Target keyword
↓
Scrape Top 10 results:
- Title
- URL
- Meta description
- Page content (H1, H2, H3 structure)
- Word count
- Content type (listicle, how-to, guide, comparison, etc.)

Step 2: Intent Analysis

Dimension Description
Search Intent Informational / Commercial / Transactional / Navigational
Content Format 90% are listicles? You should write a listicle too
Content Depth Average word count? Exceed the average
SERP Features Featured Snippet? PAA? Video?

Step 3: Topic Extraction

Extract common topics covered by Top 10:

Example keyword: "how to start a podcast"

Top 10 coverage:
✓ Equipment selection (10/10)
✓ Recording software (9/10)
✓ Hosting platforms (8/10)
✓ Cover design (7/10)
✓ Promotion strategy (6/10)

Rule: Topics covered by >50% = must include

Step 4: Gap Analysis

Find content competitors don't cover or cover poorly:

Gap opportunities:
- 2024 AI tool recommendations (only 2/10 mention)
- Monetization strategies (most skim over)
- Real cost breakdown (no specific numbers)
- Common failure reasons (few cover negative angle)

Rule: Gaps = your differentiation opportunity

Step 5: Brief Generation


Output Format: Content Brief

# Content Brief: [Target Keyword]

## Search Intent
[Informational/Commercial/etc.] - [One sentence describing what users want]

## Content Format
Recommended: [Listicle / How-to Guide / Comparison / etc.]
Reason: X/10 of Top 10 use this format

## Target Word Count
Minimum: [Top 10 average word count]
Recommended: [Average + 20%] to outperform competition

## Must-Have Topics

| Topic | Coverage | Suggested Depth |
|-------|----------|-----------------|
| [Topic 1] | 10/10 | Detailed |
| [Topic 2] | 9/10 | Detailed |
| [Topic 3] | 8/10 | Medium |

## Gap Opportunities (Differentiators)

| Gap | Why It's an Opportunity | Suggested Angle |
|-----|-------------------------|-----------------|
| [Gap 1] | Only 2/10 mention | [Specific suggestion] |
| [Gap 2] | Shallow coverage | [Specific suggestion] |

## Recommended H2 Structure

1. [H2 Title] - Covers [Topic]
2. [H2 Title] - Covers [Topic]
3. [H2 Title] - Gap opportunity: [Gap]
4. ...

## E-E-A-T Recommendations

- **Experience**: Add [specific suggestion, e.g., real case/screenshots]
- **Expertise**: Cite [data sources/expert opinions]
- **Original Value**: [What can you provide that competitors don't]

## SERP Feature Opportunities

- [ ] Featured Snippet: [Opportunity exists? Format suggestion]
- [ ] PAA: [Related questions list]
- [ ] Video: [Video needed?]

## Internal Link Suggestions

- Link to: [Related existing pages]
- Get links from: [Which pages should link to this article]
