What it does
Kysely Queries is an agent skill from exelearning/exelearning. Change eXeLearning Kysely queries, transactions, result conversions or database dialect adapters.
Its SKILL.md is about 510 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Databases. The repository describes itself as: eXeLearning is an AGPL-licensed free/libre tool to create and publish open educational resources. The licence is AGPL-3.0.
When your agent uses it
- Databases work in your project
Example prompts
- “/kysely-queries”
What it can do on your machine
Read from SKILL.md and the folder at commit 319b5d2. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
kysely.dev
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Kysely Queries loads about 507 tokens when it runs. Until then it costs about 28 tokens; SKILL.md has 229 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- description
- Change eXeLearning Kysely queries, transactions, result conversions or database dialect adapters.
Kysely queries
Read src/db/types.ts, client.ts, dialect.ts, helpers.ts, dialects/, and the affected file under
src/db/queries/. Reference paths in this paragraph after the first are relative to src/db/.
Consult Kysely documentation for the installed API.
- Query functions accept the database/transaction argument. Pass the same transaction through all related writes; do not accidentally use the global connection inside a transaction.
- Keep the project's snake_case schema and explicit result mappings. A TypeScript generic on
sql<T>does not convert runtime strings, bigints, booleans or binary data. - Reuse
supportsReturning()and existing insert/update helpers. The MySQL adapter takes the fallback path; do not add unconditional.returning()/.onConflict()from a PostgreSQL example. - Use
toBinaryData()/fromBinaryData()for Yjs updates and snapshots. mysql2 requires Buffer handling; preserve typed-array offsets when converting results. - Preserve ownership/collaborator and status filters. Projects use active/archived/inactive states;
do not invent a universal
deleted_atrule. Keep denied mutations side-effect free. - Parameterize values. Dynamic identifiers need the existing validated identifier path; never interpolate
user text into
sql.raw. Builder queries are immutable: retain the returned query when adding filters. - Prefer queries that fetch only needed data and avoid repeated per-row work, but do not impose a new
domain-object or
{data}envelope architecture on existing functions.
Run the colocated query tests and relevant helpers.spec.ts/dialect tests. Include empty results,
unauthorized access, rollback and dialect result conversions when affected. For schema changes, also
load database-migration; SQLite-only success is not evidence of all-driver compatibility.
