What is book-slug-here?

A placeholder skill template for applying a book or named approach to a task. Its author, book title, concepts, and trigger conditions have not been filled in.

It is for creating a new book- or approach-based skill after replacing the placeholders with real content.

The template shows the intended structure, but it does not yet define a usable framework or specific behavior.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00083	$0.00222
Opus 5.5	$0.00033	$0.00089
Sonnet 5.5	$0.00017	$0.00044
Haiku 4.5	$0.00008	$0.00022

Security

Grade A, and why

book-slug-here 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.

What it actually says

[Book Title]

One-line framing of what lens this skill applies and when.

Core concepts

[Concept name] — plain explanation, why it matters, how to recognize when it applies.

[Concept name] — ...

(3-8 concepts is plenty. Don't summarize the whole book — pull only what's actionable.)

How to apply this

Numbered steps for how a response/plan should be structured when this skill triggers. Be concrete about what to check, ask, or produce — not just "keep the concepts in mind."

Keep tone practical, not a book report. Apply concepts to the user's actual situation instead of dumping definitions.

Changes

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.
