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 | $0.00048 | $0.00316 |
| Opus 5 | $0.00024 | $0.00158 |
| Sonnet 5 | $0.00010 | $0.00063 |
| Haiku 4.5 | $0.00005 | $0.00032 |
Grade A, and why
xlsx 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 8d 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
Spreadsheet workflows
Keep workbook artifacts under /home/qubicl. Obtain this skill's resourceRoot from skill_view and run its helpers with /opt/qubicl/skills-venv/bin/python. The computer and workstation presets contain the pinned spreadsheet libraries; do not install packages during a task.
Useful helpers beneath <resourceRoot>/scripts/:
xlsx_read.py FILE --sheets|--json|--csv|--formulas|--notes|--namesxlsx_create.py SPEC.json OUTPUT.xlsxxlsx_edit.py FILEfor values, rows, sheets, tables, names, links, notes, and protectionxlsx_restructure.py FILEfor reference-aware row or column changescsv_to_xlsx.py INPUT.csv OUTPUT.xlsxxlsx_to_csv.py INPUT.xlsx OUTPUT.csvxlsx_recalc.py FILEwhen LibreOffice is available
Read references/restructuring.md before inserting or deleting rows or columns in a formula-heavy workbook.
Inspect workbook structure and formulas before editing. Preserve formulas unless replacement is intentional, use a new output for risky transformations, and read the result back afterward. LibreOffice recalculation is available only on workstation computers; explain that limitation rather than manufacturing cached formula values.

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.

xlsx is a skill published in the GitHub repository EldanRing/qubicl (4 stars, last pushed 3d ago), licensed Apache-2.0. It adds 48 tokens to every session and 316 once invoked, about $0.0002 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.
