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 | $0.00022 | $0.00988 |
| Opus 5.5 | $0.00009 | $0.00395 |
| Sonnet 5.5 | $0.00004 | $0.00198 |
| Haiku 4.5 | $0.00002 | $0.00099 |
Grade A, and why
fix-notebook 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 1mo 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 — 74 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Fix Notebook
Read a notebook and fix it to comply with ALL standards. Applies changes directly.
Skills to apply
datascience:notebook-standards- section order, GPU selection, imports, config cell; itsreferences/rich-output.md(colour palette, print patterns) andreferences/equations.md(unicode inline + display math)datascience:progressbars- progress bar style and patterns
Read these skills before making changes. They are the source of truth. Do NOT hardcode colors or patterns in this skill - always defer to the skills.
What to fix
Header
- Missing or sparse header -> add/rewrite with flowing prose (purpose, method, rationale)
- Bullet-list-only approach -> numbered phases with "what AND why"
- Missing output description -> add
**Output**: <artifacts>
Structure (per notebook-standards skill)
- GPU after imports -> move before
- Scattered imports -> consolidate into single cell with autoreload
- Missing reproducibility -> add set_seed
- Scattered config -> consolidate with rich summary at end
- No markdown headers before sections -> add them
- Section header without overview text below it -> add a 1-2 sentence overview (or 3-5 bullets when listy) before the first code cell of that section. File-level Header section is the sole exception
- Configuration cell with no Rich render at end -> add the sectioned
rprint(f"""[bold cyan]Configuration[/bold cyan] ...""")block per the canonical template innotebook-standards/SKILL.md - Configuration cell on a GPU notebook without
[bold]Device[/bold]sub-section showingtorch.cuda.get_device_name(0)-> add the Device block pernotebook-standards/references/gpu-setup.mdsection 5 - Markdown cell containing equations as plain text (e.g.
P(A|B) = P(B|A) * P(A) / P(B)) -> rewrite pernotebook-standardsreferences/equations.md: unicode glyphs inline, full/display equations as standalone$$...$$blocks on their own line - Markdown cell with odd number of unescaped
$(heuristic for stray dollar amounts that MathJax will eat) -> surface the cell number and ask the user whether each$is a price (escape as\$) or a math delimiter (leave + verify pairs match)
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.

fix-notebook is a skill published in the GitHub repository stellarshenson/claude-code-plugins (4 stars, last pushed today), licensed MIT. It adds 22 tokens to every session and 988 once invoked, about $0.0001 per session on Opus 5.5. 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.
