Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00134 | $0.02055 |
| Opus 5 | $0.00067 | $0.01027 |
| Sonnet 5 | $0.00027 | $0.00411 |
| Haiku 4.5 | $0.00013 | $0.00205 |
Grade A, and why
book-coherence 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 10d 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 — 163 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Coerenza Narrativa — Intra-libro e Inter-libro
Skill per verificare la coerenza interna di un libro e la coerenza tra libri diversi di una serie. Opera su due livelli: capitolo-vs-capitolo e libro-vs-libro. Leggere book-config.md per determinare serie, lingua, piattaforma e struttura del progetto.
Livello 1: Coerenza intra-libro (tra capitoli)
Caso studio narrativo
Il caso studio attraversa tutti i capitoli in ordine cronologico. Verificare:
-
Timeline — gli eventi seguono una progressione temporale coerente. Controllare riferimenti espliciti a mesi, trimestri, periodi. Confrontare con la timeline master (tipicamente in Appendice E).
-
Numeri — revenue, metriche, headcount, percentuali devono essere coerenti tra capitoli. Se nel Cap 3 l'azienda ha 45 dipendenti e nel Cap 7 ne ha 52, deve esistere un passaggio che giustifica la crescita.
-
Personaggi — ruoli, nomi, personalità devono restare consistenti. Verificare: nome sempre scritto uguale, ruolo non cambiato senza spiegazione, caratterizzazione coerente (un personaggio prudente non diventa improvvisamente avventato senza un arco narrativo).
-
Progressione realistica — il caso studio include fallimenti, correzioni e crescita graduale. Non solo successi.
Cross-reference interni
Verificare che ogni cross-reference "(vedi Capitolo N)" punti a un capitolo che effettivamente tratta quel concetto. I cross-reference devono essere bidirezionali quando entrambi i capitoli toccano lo stesso tema.
Regola: un concetto spiegato nel Capitolo N non deve essere rispiegato nei capitoli successivi. Deve essere richiamato brevemente e rimandato con cross-reference.
Framework centrale
Il framework centrale del libro deve essere:
- Introdotto nel primo terzo del libro
- Richiamato (mai rispiegato) nei capitoli successivi dove è rilevante
- Espresso con linguaggio specifico e coerente (stessi termini, stesse definizioni)
Segnalare: capitoli dove il framework dovrebbe essere presente ma è assente, o dove il linguaggio diverge dalla definizione iniziale.
What ships with it
5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

book-coherence is a skill published in the GitHub repository fullo/claude-writing-assistant-skill (2 stars, last pushed 5mo ago), licensed MIT. It adds 134 tokens to every session and 2,055 once invoked, about $0.0007 per session on Opus 5. 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.
