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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00000 | $0.00497 |
| Opus 5.5 | $0.00000 | $0.00199 |
| Sonnet 5.5 | $0.00000 | $0.00099 |
| Haiku 4.5 | $0.00000 | $0.00050 |
Grade A, and why
quality-checker 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 2mo 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 — 65 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Quality Checker Skill
Purpose
Provides a structured quality rubric for evaluating ebook chapter manuscripts, combining general quality criteria with domain-specific plugin criteria.
Quality Rubric
1. Content Accuracy (Weight: Critical)
- Key claims are factually correct and source-backed
- Technical information is current and accurate
- Code examples produce expected results
- No misleading or ambiguous statements
2. Clarity & Accessibility (Weight: High)
- Language matches target audience level
- Complex concepts are explained before being used
- Technical jargon is defined on first use
- Examples effectively illustrate concepts
3. Completeness (Weight: High)
- All outline Key Content items are covered
- No topics are mentioned but left unexplained
- Code examples include necessary context (imports, setup)
- Sufficient depth for the reader to apply knowledge
4. Structure & Flow (Weight: Medium)
- Logical progression within each chapter
- Clear heading hierarchy (H1 → H2 → H3)
- Appropriate use of lists, code blocks, emphasis
- Smooth transitions between sections
5. Code Quality (Weight: High, for technical books)
- Syntactically valid code
- Follows language conventions and best practices
- Comments explain non-obvious logic
- Realistic examples (not contrived)
6. Cross-Chapter Consistency (Weight: Medium)
- Uniform terminology throughout the book
- Consistent tone and voice
- Accurate cross-references
- No contradictions between chapters
7. Domain Plugin Criteria (Weight: Variable)
If a domain plugin quality_criteria.md exists, apply its criteria in addition to the above. Common domain criteria:
- Domain-specific terminology standards
- Citation and reference format requirements
- Required disclaimers or warnings
- Prohibited language or claims
Severity Classification
| Severity | Definition | Action |
|---|---|---|
| Blocking | Must fix before publication. Factual errors, broken code, missing critical content | Rewrite chapter |
| Non-blocking | Should fix but not a showstopper. Style issues, minor inconsistencies | Fix in editing |
| Note | Informational. Suggestions for improvement | Log only |
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.

quality-checker is a skill published in the GitHub repository lowtidebuild/ebook-writer (6 stars, last pushed 4mo ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 497 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
