feat: studio.translate.ollama v0.1.0 — Ollama-backed translate hook
First plugin to exercise the Studio-plugin translate hook end-to-end. Routes through an Ollama-shaped /api/chat endpoint configured via OLLAMA_ENDPOINT (default http://localhost:11434/api/chat). System prompt constrains the model to ONLY the translation — no commentary, no markdown frames — so the translate hook contract (plain string in, plain string out) stays honest. Declared permissions: net: localhost + net: 127.0.0.1 + net: ollama. Operator policy extends the ceiling for remote / cloud LLM endpoints. v0.1 limits: no glossary, no batching, no caching. Same SDK v0.1 single-world contract — declares Declined stubs for the theme and output-view hooks. Built artefact: ~108 KiB stripped wasm. Uploaded to releases.fai.flemming.ai (sha256 0101ed6e…) and reachable via `fai install studio.translate.ollama`. Signed-off-by: flemming-it <sf@flemming.it>

# studio.translate.ollama
|
||||||
|
|
||||||
|
Translate-Hook-Plugin für F∆I Studio. Routet `translate`-
|
||||||
|
Aufrufe durch einen konfigurierten Ollama-`/api/chat`-Endpunkt
|
||||||
|
— so wird Server-gelieferter englischer Text (MCP-Tool-
|
||||||
|
Beschreibungen, n8n-Endpunkt-Namen, `[EN]`-gebadgete Strings)
|
||||||
|
in die aktive Studio-Sprache übersetzt, just-in-time.
|
||||||
|
|
||||||
|
## Capability
|
||||||
|
|
||||||
|
- `studio.translate.ollama@0.1.0`
|
||||||
|
|
||||||
|
## Implementierter Hook
|
||||||
|
|
||||||
|
- `translate(text, from_locale, to_locale) -> string`
|
||||||
|
|
||||||
|
Die anderen beiden Studio-Plugin-Hooks (`theme`, `output-view`)
|
||||||
|
liefern `PluginError::Declined` — dieses Plugin übersetzt nur.
|
||||||
|
|
||||||
|
## Konfiguration
|
||||||
|
|
||||||
|
Liest zwei Umgebungsvariablen, die der Operator dem Plugin
|
||||||
|
über die `env:`-Berechtigung verfügbar macht:
|
||||||
|
|
||||||
|
| Variable | Default |
|
||||||
|
| ----------------- | ------------------------------------ |
|
||||||
|
| `OLLAMA_ENDPOINT` | `http://localhost:11434/api/chat` |
|
||||||
|
| `OLLAMA_MODEL` | `qwen2.5:14b` |
|
||||||
|
|
||||||
|
Für andere Endpunkte (z.B. remote Inferenz-Node):
|
||||||
|
`OLLAMA_ENDPOINT` vor `fai serve` setzen und den Host in den
|
||||||
|
`net:`-Berechtigungen unten ergänzen.
|
||||||
|
|
||||||
|
## Berechtigungen
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
permissions:
|
||||||
|
- "net: localhost"
|
||||||
|
- "net: 127.0.0.1"
|
||||||
|
- "net: ollama"
|
||||||
|
```
|
||||||
|
|
||||||
|
Operator:innen mit nicht-Loopback-Endpunkt erweitern ihre
|
||||||
|
Operator-Policy-Ceiling um den Upstream-Host.
|
||||||
|
|
||||||
|
## Wie der System-Prompt arbeitet
|
||||||
|
|
||||||
|
Das Plugin sendet zwei Nachrichten an das Modell: einen festen
|
||||||
|
System-Prompt, der die Ausgabe auf NUR die Übersetzung
|
||||||
|
einschränkt (keine Anführungszeichen, kein Kommentar, keine
|
||||||
|
Erklärung), und eine User-Message mit dem Quelltext. Der
|
||||||
|
Sprach-Hinweis steht im System-Prompt — das Modell behandelt
|
||||||
|
ihn als Anweisung, nicht als zu übersetzenden Inhalt.
|
||||||
|
|
||||||
|
So bleibt der Translate-Hook-Vertrag ehrlich: der Caller
|
||||||
|
erwartet einen reinen String zurück, keine markdown-umrahmte
|
||||||
|
LLM-Antwort.
|
||||||
|
|
||||||
|
## Grenzen in v0.1.0
|
||||||
|
|
||||||
|
- Kein Glossar / keine Terminologie-Liste — das Modell stützt
|
||||||
|
sich auf sein Allgemeinwissen.
|
||||||
|
- Kein Batching. Jeder Aufruf ist ein HTTP-Request.
|
||||||
|
- Kein Caching. Studios Plugin-Host könnte in einer späteren
|
||||||
|
Iteration einen pro-Aufruf-Cache ergänzen.
|
||||||
|
|
||||||
|

# studio.translate.ollama
|
||||||
|
|
||||||
|
Translate-hook plugin for F∆I Studio. Routes the `translate`
|
||||||
|
call through a configured Ollama-shaped `/api/chat` endpoint
|
||||||
|
so server-supplied English text (MCP tool descriptions, n8n
|
||||||
|
endpoint names, `[EN]`-badged strings) gets translated into
|
||||||
|
the active Studio locale on the fly.
|
||||||
|
|
||||||
|
## Capability
|
||||||
|
|
||||||
|
- `studio.translate.ollama@0.1.0`
|
||||||
|
|
||||||
|
## Hook implemented
|
||||||
|
|
||||||
|
- `translate(text, from_locale, to_locale) -> string`
|
||||||
|
|
||||||
|
The other two Studio-plugin hooks (`theme`, `output-view`)
|
||||||
|
return `PluginError::Declined` — this plugin only translates.
|
||||||
|
|
||||||
|
## Configuration
|
||||||
|
|
||||||
|
Reads two environment variables that the operator exposes via
|
||||||
|
the plugin's `env:` permission:
|
||||||
|
|
||||||
|
| Variable | Default |
|
||||||
|
| ----------------- | ------------------------------------ |
|
||||||
|
| `OLLAMA_ENDPOINT` | `http://localhost:11434/api/chat` |
|
||||||
|
| `OLLAMA_MODEL` | `qwen2.5:14b` |
|
||||||
|
|
||||||
|
To point at a different endpoint (e.g. a remote inference
|
||||||
|
node), set `OLLAMA_ENDPOINT` before starting `fai serve` and
|
||||||
|
make sure the host appears in the `net:` permissions below.
|
||||||
|
|
||||||
|
## Permissions
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
permissions:
|
||||||
|
- "net: localhost"
|
||||||
|
- "net: 127.0.0.1"
|
||||||
|
- "net: ollama"
|
||||||
|
```
|
||||||
|
|
||||||
|
Operators that route through a non-loopback endpoint extend
|
||||||
|
their operator-policy ceiling to include the upstream host.
|
||||||
|
|
||||||
|
## How the system prompt works
|
||||||
|
|
||||||
|
The plugin sends two messages to the model: a fixed system
|
||||||
|
prompt that constrains the output to ONLY the translation
|
||||||
|
(no quotation marks, no commentary, no explanation) and a
|
||||||
|
user message with the source text. The locale hint goes in
|
||||||
|
the system prompt so the model treats it as a directive, not
|
||||||
|
as translatable content.
|
||||||
|
|
||||||
|
This keeps the translate hook's contract honest: caller
|
||||||
|
expects a plain string back, not a markdown-wrapped LLM
|
||||||
|
response.
|
||||||
|
|
||||||
|
## Limits in v0.1.0
|
||||||
|
|
||||||
|
- No glossary / terminology list — the model relies on its
|
||||||
|
general training.
|
||||||
|
- No batching. Each call is one HTTP request.
|
||||||
|
- No caching. Studio's plugin-host may add a per-call cache
|
||||||
|
in a future iteration.
|
||||||
|

||||||
