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 | $0.00024 | $0.01885 |
| Opus 5 | $0.00012 | $0.00942 |
| Sonnet 5 | $0.00005 | $0.00377 |
| Haiku 4.5 | $0.00002 | $0.00188 |
Grade A, and why
csv-wrangling 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 — 135 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CSV Wrangling with qsv
Standard Workflow Order
Always follow this sequence when processing CSV data:
- Setup (Cowork) - If relative paths don't resolve, call
mcp__qsv__qsv_get_working_dirandmcp__qsv__qsv_set_working_dirto sync - Index -
index(enables fast random access for subsequent commands) - Discover -
sniff(detect format, encoding, delimiter) ->headers->count - Profile -
stats --cardinality --stats-jsonl(creates cache used by smart commands) - Inspect -
slice --len 5(preview rows),frequency --frequency-jsonl(value distributions with cache for reuse) - Transform - select, sort, dedup, rename, replace, search, sqlp, etc.
- Validate -
validate(against JSON Schema),stats(verify results) - Export -

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-wrangling is a skill published in the GitHub repository Kilo-Org/kilo-marketplace (175 stars, last pushed 22d ago), licensed Apache-2.0. It adds 24 tokens to every session and 1,885 once invoked, about $0.0001 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.
