v0.1.7

Simili Bot v0.1.7

This release delivers the duplicate issue auto-closer — a complete two-phase workflow for managing duplicate issues — along with OpenAI provider support, resilience improvements, and several bug fixes.

---

✨ Highlights

🤖 Duplicate Issue Auto-Closer (Phase 2)

Issues labelled potential-duplicate are now automatically closed after a configurable grace period (default: 72 h), but only when there is genuinely no human pushback. The bot detects three human-activity signals before closing:

Signal	Description
Negative reactions	👎 (-1) or 😕 (confused) on the bot's triage comment
Human reopen	Issue reopened by a non-bot user after the label was applied
Human comment	Any non-bot comment posted after the label was applied

A new simili auto-close CLI subcommand ships with this release, enabling local dry-runs and CI usage:

simili auto-close --repo owner/repo --dry-run --grace-period-minutes 5

🔌 OpenAI Provider Support

Simili Bot now supports OpenAI as an embedding and LLM provider alongside Gemini. Set your OPENAI_API_KEY and configure the provider in simili.yaml.

🔁 Exponential Backoff & Retry Hardening

Gemini API calls now retry with exponential backoff on transient failures. Retry logic uses typed error checking and an injectable RetryConfig for easier testing and customisation.

🆕 What's New

• feat: LLM model configurable via simili.yaml (llm.model, llm.provider)
• feat: CLI can now fetch issues directly from GitHub by number (--number)
• feat: Issues and PRs are visually differentiated in similar-thread reports
• feat: Environment variable validation on startup with clear error messages
• feat: Workflow concurrency control — prevents parallel triage runs on the same issue
• feat: OpenAI embedding and LLM provider support
• feat: Exponential backoff for Gemini API transient errors
• feat: Duplicate auto-closer core (grace period, label swap, closing comment)
• feat: Expanded human-activity detection (reactions, reopen, comments)
• feat: simili auto-close CLI subcommand with --dry-run and --grace-period-minutes
• ci: E2E integration test pipeline with auto-closer dry-run coverage

🐛 Bug Fixes

• Fix stale issue/PR state shown in similar-thread comments after status changes
• Prevent infinite bot comment loops on issue_comment and pull_request.edited events
• Fix closeIssue operation order (close → swap labels → comment, not comment-first)
• Fix missing pagination in auto-closer comment and event fetches
• Fix CommentAuthor population from sender for non-comment event types
• Fix E2E workflow to run only on approved reviews (security for fork PRs)

v0.1.5

Release v0.1.5

🎉 Major Features

🔧 Batch CLI Command

Process multiple issues from JSON files against the vector database without making any GitHub writes.

Features:

• Process arrays of issues from JSON files
• Support JSON (detailed) and CSV (stakeholder-friendly) output formats
• Concurrent processing with configurable worker pool
• Override collection, thresholds, and top-k via CLI flags
• Perfect for testing bot logic on historical data

Usage:

simili batch --file issues.json --out-file results.csv --format csv --workers 5

Use Cases:

• Test bot logic on historical issues without spamming repos
• Generate analysis reports for stakeholders
• Validate similarity search and duplicate detection accuracy
• Audit quality assessment without requiring write access

🌐 Web UI (simili-web)

Interactive web interface for real-time issue analysis with minimal shadcn-style design.

Features:

• Submit issues via web form (title, body, org, repo)
• View similar issues with similarity scores
• See duplicate detection with LLM reasoning
• Get quality scores and improvement suggestions
• Receive label and transfer recommendations
• Single-binary deployment with embedded static files

Usage:

export GEMINI_API_KEY=xxx QDRANT_URL=xxx QDRANT_API_KEY=xxx QDRANT_COLLECTION=xxx
./simili-web
# Open http://localhost:8080

🐛 Bug Fixes

Duplicate Detection Improvements

• Fixed: Related issues incorrectly marked as duplicates
• Root cause: Only titles were passed to LLM, not full issue bodies
• Solution: Now extracts and passes full text field from Qdrant payload
• Rewrote duplicate detection prompt to be more conservative
• Raised confidence threshold to 0.85
• Added DuplicateReason field to capture LLM reasoning

Before: Issue chain #8640 → #8641 → #8642 incorrectly marked as duplicates
After: Issues correctly identified as related but not duplicates

Transfer Detection

• Fixed transfer comment message when issue stays in current repo
• Prevent incorrect routing by including current repo in candidates

✨ Enhancements

Message Templates

• Redesigned all bot messages with professional branding
• Improved clarity and consistency across all interactions

Hybrid Routing

• Implemented hybrid routing with repository documentation learning
• Combines rule-based and VDB semantic matching for better accuracy

🔧 Technical Changes

• Extracted reusable ExecutePipeline() function for batch processing
• Added URL sanitization to prevent XSS vulnerabilities
• Improved error handling for JSON encoding operations
• Fixed parameter shadowing issues
• Updated embedding model to gemini-embedding-001

📚 Documentation

• Added comprehensive README for simili-web
• Updated main README with batch CLI usage
• Added API documentation and troubleshooting guides
• Included examples for both CLI and web UI

v0.1.0

Simili-Bot v0.1.0 - Transfer Detection & Smart Routing

This release introduces major improvements to transfer detection, smart routing, and multi-repository issue triage.

Major Features

Smart Issue Routing & Transfer System

• LLM Triage & Smart Routing (#24): Intelligent issue classification and automatic cross-repository routing using AI
• Transfer Rules Engine (#22): Configurable rules-based system for automatic issue transfers between repositories
• Transfer-First Flow with /undo Command (c760085): Issues are transferred immediately with ability to undo incorrect transfers

Transfer Loop Prevention

• GitHub API-Based Transfer Detection (#28, #25): Proper detection using GitHub timeline events API
  • Eliminates false positives from time-based heuristics
  • Accurately identifies transferred issues to prevent re-triaging
  • Queries actual "transferred" events instead of relying on creation timestamps
• Bot Comment Detection (3fdefb0): Prevents bot from triaging its own comments and creating feedback loops
• Skip Indexing for Transferred Issues (0499041): Transferred issues are no longer indexed to avoid duplicate embeddings

Critical Bug Fixes

GitHub Integration

• Repository Parsing from Webhooks (#26): Fixed parsing of repository owner/name from GitHub webhook events
• Event Action Parsing (d298c71): Properly extracts action field (opened, transferred, etc.) from webhook payloads
• TRANSFER_TOKEN Support (aed3242): Use dedicated token for cross-repository operations when available

Configuration & Inheritance

• Configuration Inheritance (c733c39, 134f875): Fixed config merging and boolean field handling in multi-repo setups
• Issue Number Extraction (60ce224): Robust extraction of issue numbers from Qdrant vector store payloads
• Similarity Search Compatibility (541ff8e): Fixed compatibility between similarity search and indexer components

Deployment & Compatibility

• Docker Action Migration (eb22f4c): Migrated to Docker-based GitHub Action for better reliability
• Go Version Standardization: Standardized on Go 1.23+ across all build environments
• Remove TUI Dependencies (a59a717): Switched to standard stdout logging for better CI/CD compatibility
• Embedding Model Updates (2f11d7c, c77eaa2): Updated to latest Gemini embedding models

Improvements

• Enhanced Debug Logging (1bda6dc): Added comprehensive logging to gatekeeper for diagnosing transfer detection
• QDRANT_URL Environment Priority (ebca28d): Prioritize environment variables over config file for container deployments
• Error Visibility (4864464): Use string slices for errors to ensure proper JSON serialization
• CODEOWNERS (#21): Added code ownership definitions

Deployment

This release uses GoReleaser for multi-platform builds:

• Linux (amd64, arm64)
• macOS (amd64, arm64)
• Windows (amd64, arm64)

Migration Notes

If upgrading from v0.0.4:

1. The bot now requires GITHUB_TOKEN (or TRANSFER_TOKEN for cross-repo transfers)
2. Transfer detection now uses GitHub API - ensure token has repo scope
3. Configuration inheritance is more robust - review your extends settings
4. LLM features require GEMINI_API_KEY environment variable

Release Stats

• 46 commits since v0.0.4
• 4 merged pull requests
• Multiple critical bug fixes for production stability
• Zero breaking changes to existing configurations
