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 | $0.00086 | $0.01526 |
| Opus 5 | $0.00043 | $0.00763 |
| Sonnet 5 | $0.00017 | $0.00305 |
| Haiku 4.5 | $0.00009 | $0.00153 |
Grade A, and why
kysely-converter 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 3d 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 — 71 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Kysely Query Workflow
Translate query intent into Kysely code using the project's schema types, dialect, and installed API. Source SQL is optional. Keep SQL semantics and the application's result contract visible throughout the task.
1. Classify the request
- Convert SQL: identify input parameters, clauses, and expected output columns before mapping methods.
- Write a query: derive tables, relationships, filtering, cardinality, ordering, and desired result shape from requirements; ask for missing schema or business rules that determine the query.
- Modify or refactor: identify the intended behavior change, or preserve behavior for a refactor. Read the existing builder, helpers, execution site, and result consumer.
- Diagnose types: obtain the exact error, failing expression, relevant table types, and expected result. Follow the diagnostic order below rather than guessing a replacement type.
2. Establish project context and version
Inspect the relevant project package manifest, installed Kysely package metadata when available, lockfile resolution, TypeScript version, database dialect/server version, driver, schema types, and nearby query code. A dependency range is not an exact installed version. Account for workspace-specific resolutions and plugins that transform queries or results.
Use the user's requested version together with installation and lock information. If they conflict, ask which version to target before choosing APIs. If no version can be confirmed, explicitly state “Assuming Kysely 0.29.5” and proceed with that baseline; do not present it as the installed version. Missing dialect, schema, or return requirements still need clarification when they affect correctness.
For 0.29.x, read the version reference before selecting APIs. For another version, verify relevant APIs against that version's official release notes and tagged source/declarations. Do not apply the 0.29 reference as proof of compatibility with older or later versions, or silently upgrade the project.
What ships with it
8 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.

kysely-converter is a skill published in the GitHub repository buYoung/skills (21 stars, last pushed 3d ago), licensed MIT. It adds 86 tokens to every session and 1,526 once invoked, about $0.0004 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.
