aptu-cli 0.3.2

CLI for Aptu - Gamified OSS issue triage with AI assistance
aptu-cli-0.3.2 is not a library.

Aptu is a context-engineering experiment: instead of throwing big models at problems, it crafts tight prompts that let smaller models do the job with fewer tokens and surprising precision.

Benchmarks

Head-to-head comparison of aptu+mercury-2 (Mercury 2, a small diffusion-based LLM by Inception Labs) vs a raw claude-opus-4.6 call (no schema, no rubric, no AST context) across 6 fixtures (3 triage, 3 PR review).

Arm Quality (mean, /5) Cost/call Latency p50
aptu+mercury-2 4.8/5 $0.0011 1,934 ms
raw claude-opus-4.6 2.2/5 $0.0193 16,032 ms

Measured across aptu #737, #850, #1094 (triage) and #1091, #1098, #1101 (PR review); n=1 per fixture.

aptu+mercury-2 is 17x cheaper and 8x faster than a raw claude-opus-4.6 call, while scoring more than twice as high on the structured rubric.

See docs/BENCHMARKS.md for full methodology, fixture breakdown, and C1-C5 scores.

Quick Start

aptu repo list             # List curated repositories
aptu issue list block/goose          # Browse issues

aptu history               # View your contributions

Security Scanning

Aptu includes built-in security pattern detection for PR reviews. Scanning is performed locally, and no code is sent to external services.

aptu pr review owner/repo#123                       # Review with security scanning
aptu pr review owner/repo#123 --output sarif        # SARIF for GitHub Code Scanning

See docs/SECURITY_SCANNING.md for SARIF upload and GitHub integration.

Prompt Customization

Aptu's built-in system prompts are compiled into the binary as defaults. You can override them per operation at runtime or append project-specific guidance globally.

See docs/CONFIGURATION.md for file paths, operation names, and examples.

GitHub Action

Auto-triage new issues with AI using any supported provider.

- uses: clouatre-labs/aptu@v0
  with:
    github-token: ${{ secrets.GITHUB_TOKEN }}
    openrouter-api-key: ${{ secrets.OPENROUTER_API_KEY }}

Options: apply-labels, no-comment, skip-labeled, dry-run, model, provider.

See docs/GITHUB_ACTION.md for setup and examples.

MCP Server

Integrate aptu with AI tools via the Model Context Protocol (MCP). Supports stdio (goose, Claude Desktop) and HTTP (remote/containerized).

See docs/MCP_SERVER.md for client configuration and Docker deployment.

Configuration

See docs/CONFIGURATION.md for AI provider setup.

Models

Use aptu models list to discover available models from all configured providers.

Discovering models

aptu models list                                # all providers
aptu models list --provider openrouter          # OpenRouter only

Filtering and sorting

Flag Description
--provider Filter to a specific provider
--sort name|context Sort by name or context window size
--min-context N Show only models with at least N tokens of context
--filter TEXT Filter by name or ID (case-insensitive substring match)

Free-tier models

OpenRouter exposes pricing data for each model. Models with zero prompt and completion cost are labeled free in the output. Use --provider openrouter to browse free models.

Security

  • OpenSSF Best Practices Silver - Fewer than 1% of open source projects reach this level
  • SLSA Level 3 - Provenance attestations for all releases
  • REUSE/SPDX - License compliance for all files
  • Signed Commits - GPG-signed commits required
  • Dependency Scanning - Automated updates via Renovate

See SECURITY.md for reporting and verification.

Architecture

Aptu is a multi-crate Rust workspace. See docs/ARCHITECTURE.md for the full crate structure, data flow, and key dependencies.

Roadmap

See docs/ROADMAP.md for the project direction across near-term, medium-term, and long-term horizons.
