Pete

A Matrix news bot that ingests RSS feeds from curated sources, classifies stories using a local LLM, deduplicates semantically, and routes posts to the appropriate channel.

Features

• RSS ingestion from configurable sources (Guardian, Ars Technica) with per-source polling intervals
• Two-tier classification — Tier 1 sources use direct routing or lightweight LLM routing; Tier 2 (wire services) use a keyword gating pipeline before LLM
• Semantic deduplication — GUID exact match + LLM-based cross-source duplicate detection
• Metered release — per-channel post queues with minimum interval (5min) and burst cap (3/30min)
• Reaction tracking — records emoji reactions on posts for classifier tuning
• FTS5 search — full-text search across headlines and ledes
• Image validation — HEAD-based checks filter tracking pixels, uploads valid images via MXC

Channels

Channel	Purpose
tech	Technology news, product/industry stories
politics	Political, policy, current events (default/catch-all)
gaming	Gaming news, releases, platform announcements (no active sources yet)

Requirements

• Go 1.25+
• Ollama running locally or on a reachable host
• A Matrix account for Pete with access to target rooms
• SQLite (bundled via pure Go driver, no CGo)
• No CGo dependencies — E2EE uses pure Go crypto (goolm) via mautrix v0.28

Setup

# Clone and build
git clone <repo-url> && cd pete
go build -tags goolm .

# Create config from example
cp config.example.yaml config.yaml
# Edit config.yaml — fill in Matrix credentials, room IDs, Ollama endpoint

# First run: seed current feed items as seen (prevents flood)
./pete -config config.yaml -seed

# Post one story to verify the pipeline
./pete -config config.yaml -test

# Run
./pete -config config.yaml

Configuration

See config.example.yaml for the full structure. Key sections:

• matrix — homeserver, credentials, channel room IDs, optional admin room
• ollama — base URL, model name, timeout
• posting — rate limiting (min interval, burst cap)
• storage — database path, retention windows
• sources — RSS feeds with tier, polling interval, feed hint, optional direct routing

Environment variables can be referenced with ${VAR} syntax in the YAML.

Flags

Flag	Description
-config <path>	Path to config file (default: config.yaml)
-seed	Ingest all current feed items as seen without posting, then exit
-test	Post one story to verify the full pipeline, then exit

Docker

docker compose up -d

Set PETE_PASSWORD in your environment or a .env file for the Matrix password.

Architecture

RSS Feed → Poller → GUID Dedup → Store → Classifier → Semantic Dedup → Image Validate → Queue → Matrix
                                            ↓
                                    Direct Route (no LLM)
                                         or
                                    Ollama /api/chat (Tier 1 routing)
                                         or
                                    Keyword Gating → Ollama (Tier 2)

Packages

Package	Purpose
internal/config	YAML config loading with ${ENV} expansion
internal/storage	SQLite with WAL, FTS5, all queries
internal/ingestion	Per-source RSS polling, feed parsing, image validation
internal/classifier	Ollama client, Tier 1/2 prompts, JSON repair, keyword gating
internal/matrix	Password auth with device persistence, posting, reaction listener
internal/poster	Per-channel metered release queue, reaction tracking

Post Format

[lead image if valid]
**Headline** → article_url
Lede text from feed
`source name`

Gaming stories append platform tags: `source` · `nintendo-switch` · `pc`
