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 | $0.00033 | $0.00527 |
| Opus 5 | $0.00016 | $0.00264 |
| Sonnet 5 | $0.00007 | $0.00105 |
| Haiku 4.5 | $0.00003 | $0.00053 |
Grade A, and why
using-data-agent-skills 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.

Using Data Agent Skills
Overview
This legacy entry point remains for compatibility with older setups. The preferred start-here skill is using-data-engineering-agent-skills, which provides the current classification flow, preset mapping, example routing, and next-command guidance.
When to Use
- loading an older project that still points to this skill
- triaging a request before switching to the current entry skill
- preserving compatibility for previously installed rule bundles
Do not use this as the long-term default. Switch to skills/using-data-engineering-agent-skills/SKILL.md once the session starts.
Workflow
-
Redirect the session to
skills/using-data-engineering-agent-skills/SKILL.md.- Treat that skill as the default router.
- Use it to choose the platform preset, example, and next command.
-
Preserve older references safely.
- If docs, rules, or prompts still mention
using-data-agent-skills, do not fail the session. - Treat the old name as an alias, not a separate workflow.
- If docs, rules, or prompts still mention
-
Continue with the real task skill.

Common Rationalizations
| Rationalization | Reality |
|---|---|
| "The old start-here skill is good enough." | The newer entry skill has the current routing logic, examples, and command mapping. |
| "We can keep using both as separate workflows." | Treat the old name as an alias so the repository does not drift into duplicate behavior. |
| "Renaming the start-here skill is risky." | Compatibility is preserved as long as this alias continues to redirect cleanly. |
Red Flags
- the session keeps this alias loaded instead of the newer start-here skill
- docs or rules reference two different entry skills as if both are primary
- the agent skips preset or command selection after triage
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.

using-data-agent-skills is a skill published in the GitHub repository vaquarkhan/data-engineering-agent-skills (45 stars, last pushed 3mo ago), licensed MIT. It adds 33 tokens to every session and 527 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 2026-09-03.
