A read-only proofreading skill for lecture files written in LaTeX or Quarto, a tool for creating documents and presentations from plain-text source files.

Use it to check lecture slides for grammar, typos, inconsistent terms, academic writing issues, and content that does not fit on the page or slide.

It finds writing, formatting, overflow, and terminology problems without changing the original files.

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	$0.00077	$0.00487
Opus 5.5	$0.00031	$0.00195
Sonnet 5.5	$0.00015	$0.00097
Haiku 4.5	$0.00008	$0.00049

Security

Grade A, and why

proofread 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 22d 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

Proofread Lecture Files

Run the proofreading protocol on lecture files. This produces a report of all issues found WITHOUT editing any source files.

Steps

Identify files to review:
- If $ARGUMENTS is a specific filename: review that file only
- If $ARGUMENTS is "all": review all lecture files in Slides/ and Quarto/
For each file, launch the proofreader agent that checks for:

GRAMMAR: Subject-verb agreement, articles (a/an/the), prepositions, tense consistency TYPOS: Misspellings, search-and-replace artifacts, duplicated words OVERFLOW: Overfull hbox (LaTeX), content exceeding slide boundaries (Quarto) CONSISTENCY: Citation format, notation, terminology ACADEMIC QUALITY: Informal language, missing words, awkward constructions
Produce a detailed report for each file listing every finding with:
- Location (line number or slide title)
- Current text (what's wrong)
- Proposed fix (what it should be)
- Category and severity
Save each report to quality_reports/:
- For .tex files: quality_reports/FILENAME_report.md
- For .qmd files: quality_reports/FILENAME_qmd_report.md
Leave source files unchanged — fixes are applied after the user reviews the report. Only produce the report. Fixes are applied separately after user review.
Present summary to the user:
- Total issues found per file
- Breakdown by category
- Most critical issues highlighted

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.
