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 | $0.01020 |
| Opus 5 | $0.00030 | $0.00510 |
| Sonnet 5 | $0.00012 | $0.00204 |
| Haiku 4.5 | $0.00006 | $0.00102 |
Grade A, and why
csv-pipeline 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 9d 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 — 126 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CSV Data Pipeline
Process tabular data (CSV, TSV, JSON, JSON Lines) using standard command-line tools and Python. No external dependencies required beyond Python 3.
When to use this skill
- User provides a CSV/TSV/JSON file and asks to analyze, transform, or report on it
- Joining, filtering, grouping, or aggregating tabular data
- Converting between formats (CSV to JSON, JSON to CSV, etc.)
- Deduplicating, sorting, or cleaning messy data
- Generating summary statistics or reports
- ETL workflows: extract from one format, transform, load into another
Scripts overview
| Script | Purpose | Dependencies |
|---|---|---|
csv_tool.py |
All-in-one CSV/JSON processing tool | Python 3 (stdlib only) |
Steps
1. Ensure Python 3 is available
python --version
CRITICAL — Error Recovery: If any script below fails with an error, check that Python 3 is available and re-run the exact same command.
2. Inspect a data file
python scripts/csv_tool.py inspect "DATA_FILE"
Shows row count, column names, and non-empty value counts per column.
3. Filter rows
python scripts/csv_tool.py filter "DATA_FILE" --column COLUMN_NAME --op OPERATOR --value VALUE --output "OUTPUT_FILE"
Operators: eq, neq, gt, gte, lt, lte, contains, startswith, endswith
4. Sort data
python scripts/csv_tool.py sort "DATA_FILE" --column COLUMN_NAME --order asc --output "OUTPUT_FILE"
Options: --numeric for numeric sorting, --order desc for descending.
5. Deduplicate
python scripts/csv_tool.py dedup "DATA_FILE" --columns "col1,col2" --output "OUTPUT_FILE"
Remove duplicates by specified columns (or all columns if omitted).
6. Aggregate / Group By
python scripts/csv_tool.py aggregate "DATA_FILE" --group-by COLUMN --agg-column VALUE_COL --func sum --output "OUTPUT_FILE"
What ships with it
1 file 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.

csv-pipeline is a skill published in the GitHub repository AIDotNet/OpenCowork (634 stars, last pushed 5d ago), licensed Apache-2.0. It adds 61 tokens to every session and 1,020 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 2026-08-30.
