tipsofday — a daily crypto briefing written on your own laptop by a local Gemma model

Description and use

tipsofday produces a daily crypto briefing locally with an open‑weight Gemma 4 model, avoiding external data transfer, saving user time, and maintaining privacy.

Problem

Crypto professionals spend ~45 min each morning aggregating headlines and prices before drafting a briefing, risking time loss and privacy exposure.

Outcome

The tool delivers a valid JSON briefing in ~23 s per call, with $0.00 API spend, zero prompt‑injection artefacts, and correct handling of thin‑news days.

Workflow

• 1. Install the tool via pipx install .
• 2. Pull the Gemma 4 model with ollama pull gemma4:e4b
• 3. Execute tipsofday run --refresh --lang en to fetch feeds, prices, and generate briefing

Evidence

Every sentence the user reads is written by an open‑weight model running through Ollama, defaulting to gemma4:e4b

Source

The short version, on an RTX 5050 (8 GB): Valid JSON, per call 1.00; Prompt‑injection artefacts that reached the output 0; Mean latency per briefing 22.9 s; Cost in API spend $0.00

Source

A guardrail silently disabled the product. The model kept naming BTC (negative news ⇒ ineligible), so the app returned "no clear signal" on 6 of 6 days

Source

A security guardrail was dead code. A later security pass found the prompt‑injection scrubber — written and unit‑tested — was never actually called by the pipeline
