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.

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 | $0.00061 | $0.01543 |
| Opus 5 | $0.00030 | $0.00772 |
| Sonnet 5 | $0.00012 | $0.00309 |
| Haiku 4.5 | $0.00006 | $0.00154 |
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.
How it starts
The opening of the file, as written. The whole thing — 130 lines — stays where its author put it; the contents beside it link to each section on GitHub.
XLSX
Use this skill whenever the user asks to create, inspect, analyze, or edit an .xlsx workbook, or to turn delimited tabular data into a polished .xlsx file.
Default Workflow
- For creation tasks, use
skills/xlsx/scripts/create_xlsx.cjsto create a new workbook from headers/rows or JSON data. Fall back to a workspace.cjsscript only when the bundled script cannot handle the requirement. - Use
skills/xlsx/scripts/import_delimited.cjsfor messy CSV or TSV inputs when it saves time, then polish the workbook withxlsx-populate. - Do table reshaping in plain JavaScript, then write the final workbook with
xlsx-populate. - After meaningful formula edits, run LibreOffice-backed recalculation when
sofficeis available so cached values and error checks are current. - Save the finished workbook inside the workspace and return the
.xlsxartifact.
Rules
- Keep formulas as formulas. Do not replace derived cells with hardcoded values unless the user explicitly asks for static outputs.
- Keep formulas dynamic. Put user-editable assumptions and drivers in dedicated cells or sheets instead of burying hardcoded constants inside long formulas.
xlsx-populatedoes not recalculate formulas. Keep formula strings intact and use LibreOffice-backed verification when cached values matter and the runtime sayssofficeis available.- After significant formula edits, run
node skills/xlsx/scripts/recalc.cjs workbook.xlsx --jsonwhensofficeis available and fix any#REF!,#DIV/0!,#VALUE!,#N/A, or#NAME?errors before delivery. - Match existing workbook conventions exactly when editing templates or established models. Existing fonts, fills, borders, number formats, freeze panes, filters, named ranges, and color conventions override generic style rules.
- For new user-facing workbooks without a template, use consistent professional styling: one readable font, explicit header styling, sensible widths, and alignment or freeze panes where they help readability.
- Preserve existing worksheets, named ranges, freeze panes, filters, and formats unless the user asked for a redesign.
- Prefer
.xlsxas the final deliverable. Only fall back to CSV/TSV if the user explicitly wants a flat export. - Use number formats, explicit column widths, alignment, and header styling for user-facing workbooks.
- For creation tasks ("make a spreadsheet", "create an xlsx"), always use
skills/xlsx/scripts/create_xlsx.cjsfirst. Only write a custom workspace script if the user's requirements exceed what the bundled script supports. - Treat
skills/as bundled tooling. Do not write generated task scripts underskills/xlsx/orskills/office/for normal workbook jobs. - Put new helper scripts in workspace
scripts/or the workspace root, then run them from there. Useskills/xlsx/scripts/...andskills/office/...only as shipped helper commands.
What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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 HybridAIOne/hybridclaw (132 stars, last pushed yesterday), licensed MIT. It adds 61 tokens to every session and 1,543 once invoked, about $0.0003 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 2026-09-03.
