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 | $0.03687 | $0.03687 |
| Opus 5 | $0.01843 | $0.01843 |
| Sonnet 5 | $0.00737 | $0.00737 |
| Haiku 4.5 | $0.00369 | $0.00369 |
Grade A, and why
huginnDB CLAUDE.md scanned grade A with 1 finding 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 yesterday.
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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Identity
- HuginnDB — desktop database manager, Tauri 2 (Rust backend) + React + TypeScript frontend.
- Targets PostgreSQL, MySQL, SQLite, MongoDB, and Microsoft SQL Server. Inspired by HeidiSQL but minimal-UI / keyboard-first / Monaco-everywhere.
- Public repo: https://github.com/Alexfp28/huginnDB.
- License: MIT. Status: 1.21.x (stable; SemVer applies). MongoDB support landed in 1.1.0; the headless MCP connector (
huginndb-mcp) landed across the 1.5–1.9 line (per-connection write policy in 1.9.0); HuginnDB Pulse (live server health/performance monitoring, MySQL + MongoDB) landed in 1.20.0.
Maintainer / collaboration notes
- Sole maintainer: Alexfp28 (
[email protected]). Security contact:[email protected]. - User communicates in Spanish; reply in Spanish. Code, comments, commit messages, and docs are English.
- Conventional Commits (
feat:,fix:,refactor:,docs:,chore:, …) with long-form bodies explaining the why. The user explicitly values verbose commits — never punt with a one-liner on non-trivial changes. - Keep
CHANGELOG.mdin sync (Keep a Changelog format). Add toUnreleasedas you go; the user will cut releases manually. CHANGELOG.es.mdis the Spanish translation ofCHANGELOG.mdand must be updated in the same turn, never as a follow-up. Every entry added toCHANGELOG.md'sUnreleasedsection gets its translated counterpart added toCHANGELOG.es.md's[Sin publicar]section right away — this is the thing that keeps getting forgotten, so treat "update the changelog" as meaning both files unless told otherwise.
Tech stack quick reference
| Layer | Choice |
|---|---|
| Shell | Tauri 2 (@tauri-apps/cli, @tauri-apps/api) |
| Frontend | React 18 + TS strict, Vite |
| Styling | Tailwind CSS + shadcn-style Radix primitives |
| State | Zustand (with persist for theme / history / saved) |
| Data grid | TanStack Table v8 |
| Editor | Monaco — self-hosted, no CDN (src/lib/monaco/monaco-setup.ts) |
| DB drivers | sqlx 0.8 (postgres, mysql, sqlite) + mongodb 3 (bson-3) + tiberius 0.12 (SQL Server; sqlx has no MSSQL driver) |
| Credentials | keyring crate (Windows Credential Manager / libsecret) |
| Package mgr | pnpm only. Never suggest npm or yarn. |
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.
