What is book_file.rename?

A file-renaming task for books and research papers that applies a standard filename format. It uses `git mv` when the file is tracked by Git, a version-control system.

Use it to rename a book or paper file using its year, first author's surname, title, and existing extension.

Consistent filenames make references easier to find and keep organized without changing the file contents.

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	$0.00012	$0.00126
Opus 5.5	$0.00005	$0.00050
Sonnet 5.5	$0.00002	$0.00025
Haiku 4.5	$0.00001	$0.00013

Security

Grade A, and why

book_file.rename 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 yesterday.

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

Goal

Given the name of a file storing a book or a paper, rename it to match the format in .claude/skills/references.rules.md # Format to Use in File Names

Workflow

Use git mv if the file is under source control

Verification

Confirm the new file name follows <Year>.<Last_name_of_first_author>_[et_al].<Title>
Confirm the file extension is unchanged

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.
