Simili Bot

AI-Powered GitHub Issue Intelligence

Automatically detect duplicate issues, find similar issues with semantic search, and intelligently route issues across repositories.

---

Features

• Semantic Duplicate Detection — Find related issues using AI-powered embeddings, not just keyword matching.
• Cross-Repository Search — Search for similar issues across your organization.
• Intelligent Routing — Automatically transfer issues to the correct repository based on content.
• Smart Triage — AI-powered labeling and quality assessment.
• Modular Pipeline — Customize workflows with plug-and-play steps.
• Multi-Repo Support — Central configuration with per-repo overrides.

Architecture

Simili uses a "Lego with Blueprints" architecture:

• Lego Blocks: Independent, reusable pipeline steps (Gatekeeper, Similarity, Triage, etc.).
• Blueprints: Pre-defined workflows for common use cases.
• State Branch: Git-based state management using an orphan branch (no comment scanning).

Quick Start

Simili-Bot supports both Single-Repository and Organization-wide setups.

Setup Guides

Guide	Description
Single Repo Setup	Instructions for setting up Simili-Bot on a standalone repository.
Organization Setup	Best practices for deploying across an organization using Reusable Workflows.

Examples

We provide copy-pasteable examples to get you started quickly:

• Multi-Repo Examples: Includes shared workflow, caller workflow, and central config.
• Single-Repo Examples: Standard workflow and configuration.

Available Workflows

You can specify a workflow in your simili.yaml or define custom steps.

Preset	Description
issue-triage	Full pipeline: similarity search, duplicate check, triage analysis, and action execution.
similarity-only	Runs similarity search only. Useful for "Find Similar Issues" features without auto-triage.
index-only	Indexes issues to the vector database without providing feedback.

CLI Commands

Simili provides a powerful CLI for local development, testing, and batch operations.

simili index

Bulk index issues from a GitHub repository into the vector database.

simili index --repo owner/repo --workers 5 --limit 100

Flags:

• --repo (required): Target repository (owner/name)
• --workers: Number of concurrent workers (default: 5)
• --since: Start from issue number or timestamp
• --limit: Maximum issues to index
• --dry-run: Simulate without writing to database

simili process

Process a single issue through the pipeline.

simili process --issue issue.json --workflow issue-triage --dry-run

Flags:

• --issue: Path to issue JSON file
• --workflow: Workflow preset to run (default: "issue-triage")
• --dry-run: Run without side effects
• --repo, --org, --number: Override issue fields

simili batch

Process multiple issues from a JSON file in batch mode. All operations run in dry-run mode to prevent GitHub writes.

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

Use Cases:

• Test bot logic on historical data without spamming repositories
• Generate reports showing similarity analysis and duplicate detection
• Analyze issues from repositories where you lack write access
• Bulk identify transfer recommendations and quality scores

Flags:

• --file (required): Path to JSON file with array of issues
• --out-file: Output file path (stdout if not specified)
• --format: Output format: json or csv (default: json)
• --workers: Number of concurrent workers (default: 1)
• --workflow: Workflow preset (default: "issue-triage")
• --collection: Override Qdrant collection name
• --threshold: Override similarity threshold
• --duplicate-threshold: Override duplicate confidence threshold
• --top-k: Override max similar issues to show

Input Format:

Create a JSON file with an array of issues:

[
  {
    "org": "owner",
    "repo": "repo-name",
    "number": 123,
    "title": "Issue title",
    "body": "Issue description...",
    "state": "open",
    "labels": ["bug", "high-priority"],
    "author": "username",
    "created_at": "2026-02-10T10:00:00Z"
  }
]

Output Formats:

• JSON: Full pipeline results with detailed analysis
• CSV: Flattened summary for spreadsheet analysis

Example Workflow:

# 1. Index repository issues
simili index --repo ballerina-platform/ballerina-library --workers 10

# 2. Prepare test issues in batch.json
# 3. Run batch analysis
simili batch --file batch.json --format csv --out-file analysis.csv --workers 5

# 4. Review results
cat analysis.csv
