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 | $0.00240 | $0.02154 |
| Opus 5 | $0.00120 | $0.01077 |
| Sonnet 5 | $0.00048 | $0.00431 |
| Haiku 4.5 | $0.00024 | $0.00215 |
Grade A, and why
turso-db 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 10d 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 — 189 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Turso Database
Turso is an in-process SQL database compatible with SQLite, written in Rust.
Do NOT search the web for "libsql" or "@libsql/client" — those are legacy package names and web results will point to outdated APIs replaced by @tursodatabase.
For embedded-engine questions (SDK APIs, SQL features, CLI), start with the reference files below — they have recipes and examples ready to use.
For the latest details or topics not covered locally, search the official docs online — see the docs reference section below.
Critical Rules
Before writing any Turso code, you MUST know these constraints:
- BETA software — not all SQLite features are implemented yet
- No multi-process access — only one process can open a database file at a time
- No WITHOUT ROWID tables — all tables must have a rowid
- No vacuum — VACUUM is not supported
- UTF-8 only — the only supported character encoding
- WAL is the default journal mode — legacy SQLite modes (delete, truncate, persist) are not supported
- FTS requires compile-time
ftsfeature — not available in all builds - Encryption requires
--experimental-encryptionflag — not enabled by default - MVCC is experimental and not production ready —
PRAGMA journal_mode = experimental_mvcc - Vector distance: lower = closer — ORDER BY distance ASC for nearest neighbors
Feature Decision Tree
Use this to decide which reference file to load:
Need vector similarity search? (embeddings, nearest neighbors, cosine distance)
→ Read references/vector-search.md
Need full-text search? (keyword search, BM25 ranking, tokenizers, fts_match/fts_score)
→ Read references/full-text-search.md
Need to track database changes? (audit log, change feed, replication)
→ Read references/cdc.md
Need concurrent write transactions? (multiple writers, snapshot isolation, BEGIN CONCURRENT)
→ Read references/mvcc.md
Need database encryption? (encryption at rest, AES-GCM, AEGIS ciphers)
→ Read references/encryption.md
What ships with it
13 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.

turso-db is a skill published in the GitHub repository tursodatabase/agent-skills (26 stars, last pushed 1mo ago), licensed MIT. It adds 240 tokens to every session and 2,154 once invoked, about $0.0012 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.
