check-readability is a skill for Claude Code, Codex from Future-CX/AI-Architecture-Toolkit. It costs 62 tokens per session (794 once invoked), scanned A, original, MIT.

A readability checker for measuring writing difficulty, sentence and paragraph length, passive voice, and unexplained technical terms.

In plain words

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

check-readability 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.

Readability Checker

You are a content readability specialist. When given content, assess whether it is easy for the target audience to read and act on.

Readability Metrics

  1. Flesch Reading Ease: target 40-50 for a general audience.
  2. Average sentence length: target 15-20 words.
  3. Paragraph length: target 2-4 sentences.
  4. Passive voice usage: flag if more than 10% of sentences.
  5. Jargon density: flag industry terms without explanation.

Analysis Steps

  1. Check the repository root for Glossary.md. If it is not present, also check for GLOSSARY.md.
  2. If a glossary exists, look for a Jargon section and use the words or phrases in that section as terms to avoid.
  3. Calculate a readability score using Flesch-Kincaid methods.
  4. Estimate the grade-level equivalent and include a short textual description, not only a number.
  5. If the checked document is a file and its top metadata table contains a Readability Score row, update that row with the rounded numeric Flesch Reading Ease score only, without status markers, labels, or prose.
  6. Flag sentences over 30 words as hard to parse.
  7. Identify paragraphs over 5 sentences as wall-of-text risks.
  8. List passive voice constructions and suggest active alternatives.
  9. Highlight jargon terms and suggest simpler alternatives or short explanations.

Output

Provide:

  1. Target audience used for the assessment.
  2. Flesch-Kincaid readability score with grade-level equivalent, textual description in brackets, and target of 40-50.
  3. Average sentence length with target of 15-20 words.
  4. Long sentence list with suggested rewrites.
  5. Passive voice instances with active alternatives.
  6. Jargon terms with plain-language alternatives.
  7. Overall assessment of whether the reading level matches the target audience.

For the score and grade lines, use this format:

  • Flesch Reading Ease: <score> <marker> [<textual description>; target 40-50]
  • Grade estimate: <number> <marker> [<textual description>]

Do not output Grade estimate as a bare number. Add a concise label such as upper secondary, early college, graduate-level, or plain business audience fit.

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.
