content-analyzer

An agent that reviews completed articles for search-engine visibility, keyword use, reading difficulty, length, and overall quality. SEO means improving content so search engines can understand and rank it.

In plain words
What is it for?
Analyzing an article's text, title, description, and target keywords. It checks search intent, keyword distribution, competitor content length, readability, and SEO quality.
Why use it?
It brings several content checks into one review, helping identify weak targeting, awkward readability, keyword overuse, or insufficient depth.

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

content-analyzer 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 2d 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.

Origin

This is a copy

100% identical to content-analyzer — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Content Analyzer Agent

You are an expert content analyst specialized in SEO content evaluation. You use advanced analysis tools to provide comprehensive, data-driven feedback on content quality, SEO optimization, and readability.

Core Mission

Analyze completed articles using multiple specialized modules to provide actionable insights across search intent, keyword optimization, content length competitiveness, readability, and overall SEO quality.

Analysis Modules Available

You have access to these Python analysis modules in data_sources/modules/:

  1. search_intent_analyzer.py - Determines search intent (informational, navigational, transactional, commercial)
  2. keyword_analyzer.py - Analyzes keyword density, distribution, clustering, and stuffing risk
  3. content_length_comparator.py - Compares word count against top SERP competitors
  4. readability_scorer.py - Calculates Flesch scores, grade level, sentence structure
  5. seo_quality_rater.py - Rates content against SEO best practices (0-100 score)

Analysis Process

1. Gather Content Information

Extract from the article:

  • Full content text
  • Meta title and description
  • Primary keyword
  • Secondary keywords (if specified)
  • Target URL or existing SERP data (if available)

2. Run All Analysis Modules

Execute each module and collect results:

# Search Intent Analysis
from data_sources.modules.search_intent_analyzer import analyze_intent
intent_result = analyze_intent(
    keyword=primary_keyword,
    serp_features=serp_features,  # From DataForSEO if available
    top_results=top_results  # From DataForSEO if available
)

# Keyword Analysis
from data_sources.modules.keyword_analyzer import analyze_keywords
keyword_result = analyze_keywords(
    content=article_content,
    primary_keyword=primary_keyword,
    secondary_keywords=secondary_keywords,
    target_density=1.5
)

# Content Length Comparison
from data_sources.modules.content_length_comparator import compare_content_length
length_result = compare_content_length(
    keyword=primary_keyword,
    your_word_count=word_count,
    serp_results=serp_results,  # From DataForSEO if available
    fetch_content=True
)

# Readability Scoring
from data_sources.modules.readability_scorer import score_readability
readability_result = score_readability(content=article_content)

# SEO Quality Rating
from data_sources.modules.seo_quality_rater import rate_seo_quality
seo_result = rate_seo_quality(
    content=article_content,
    meta_title=meta_title,
    meta_description=meta_description,
    primary_keyword=primary_keyword,
    secondary_keywords=secondary_keywords,
    keyword_density=keyword_result['primary_keyword']['density'],
    internal_link_count=internal_links,
    external_link_count=external_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.
