🔥 High Priority Suggestions

1. Performance Regression Detector

Purpose: Automatically detect performance regressions in solver benchmarks to maintain Z3's performance characteristics.

Problem Being Solved:

Z3's performance is critical for production users
Performance regressions can silently degrade solver efficiency
Manual performance testing is time-consuming and inconsistent
No automated baseline comparison on PRs

Trigger: pull_request (when PRs modify solver code)

Tools Needed:

GitHub API (toolsets: [default])
Bash for running benchmarks and comparing results
Network defaults for downloading benchmark suites

Safe Outputs:

add-comment: Report performance results on PRs (max 3 comments)

Value:

Critical for maintaining Z3's reputation as a high-performance solver
Prevents performance regressions from reaching main branch
Provides objective performance data for reviewers
Catches issues before users encounter them

Implementation Notes:

Use existing Z3 benchmark suite (examples/SMT-LIB2/)
Compare PR branch against main branch baseline
Report significant regressions (>5-10% slowdown)
Include timing data and memory usage
Optional: Track performance over time

Example Workflow:

---
description: Detect performance regressions in solver benchmarks
on:
  pull_request:
    types: [opened, synchronize]
    paths: 
      - 'src/**/*.cpp'
      - 'src/**/*.h'
      - 'src/**/*.hpp'
permissions: read-all
timeout-minutes: 60
tools:
  github:
    toolsets: [default]
  bash: [":*"]
safe-outputs:
  add-comment:
    max: 3
---

Similar Workflows: soundness-bug-detector.md (PR-triggered testing pattern)

Consistency: Suggested in Run 20, 21, 22, 23, 24 (5 consecutive runs)

2. Issue Triage & Labeling Assistant

Purpose: Automatically triage and label incoming issues to reduce maintainer overhead and improve issue organization.

Problem Being Solved:

72 unlabeled issues currently in the repository
Maintainers spend significant time manually triaging issues
Inconsistent labeling leads to poor prioritization
Issues get lost without proper categorization

Trigger: issues (when issues are opened or edited)

Tools Needed:

GitHub API (toolsets: [default])
Bash for text analysis
Serena for codebase analysis (identifying components)

Safe Outputs:

create-discussion: For ambiguous cases needing human input

Value:

High ROI - Reduces maintainer time significantly
Improves issue discoverability and prioritization
Helps route issues to appropriate experts
Maintains clean issue tracker

Implementation Notes:

Analyze issue title, body, and stack traces
Detect categories: bug, performance, feature-request, question, etc.
Identify solver components: SAT, SMT, theory solvers (arithmetic, strings, arrays, etc.)
Suggest platform labels: Windows, Linux, macOS
Suggest language binding labels: Python, Java, C#, etc.
Cannot directly apply labels (safe-outputs limitation), but can create discussion with recommendations

Label Categories to Suggest:

Type: bug, enhancement, performance, question, documentation
Component: sat-solver, smt, theory-arithmetic, theory-strings, theory-arrays, api, build
Platform: windows, linux, macos, cross-platform
Language: python-api, java-api, csharp-api, cpp-api, ocaml-api
Priority: critical, high, medium, low (based on severity indicators)

Example Workflow:

---
description: Triage and suggest labels for new issues
on:
  issues:
    types: [opened, edited]
permissions: read-all
tools:
  github:
    toolsets: [default]
  bash: [":*"]
  serena: ["cpp", "python"]
safe-outputs:
  create-discussion:
    category: "Issue Triage"
    max: 1
---

Similar Workflows: soundness-bug-detector.md (issue analysis pattern)

Consistency: Suggested in Run 20, 21, 22, 23, 24 (5 consecutive runs)

Current Need: 72 unlabeled issues represent significant opportunity for this workflow

3. Cross-Language Example Validator

Purpose: Automatically validate that example code across all 9 language bindings compiles and runs correctly.

Problem Being Solved:

Z3 has 9 language bindings with 20+ examples each
Examples can break when APIs change
Manual testing of all examples is impractical
Users encounter broken examples, damaging trust

Trigger: schedule: weekly and pull_request (when API changes occur)

Tools Needed:

GitHub API (toolsets: [default])
Bash for compilation and execution
Language-specific toolchains (Python, Java, C#, OCaml, JavaScript, etc.)
Network defaults for installing dependencies

Safe Outputs:

create-discussion: Report validation results
close-older-discussions: true (avoid clutter)

Value:

Quality assurance for 9 language bindings
Prevents broken examples from reaching users
Detects API breaking changes early
Maintains Z3's reputation for quality documentation

Implementation Notes:

Test examples from examples/ directory:
- examples/c/
- examples/c++/
- examples/python/
- examples/java/
- examples/dotnet/ (C#)
- examples/ocaml/
- examples/javascript/
- etc.
Compile examples with appropriate toolchains
Run examples and validate output (when applicable)
Report compilation errors, runtime errors, and API incompatibilities
Weekly validation ensures continuous monitoring

Example Workflow:

---
description: Validate example code across all language bindings
on:
  schedule: weekly
  pull_request:
    paths:
      - 'src/api/**'
      - 'examples/**'
permissions: read-all
timeout-minutes: 45
network: defaults
tools:
  github:
    toolsets: [default]
  bash: [":*"]
safe-outputs:
  create-discussion:
    close-older-discussions: true
---

Similar Workflows: api-coherence-checker.md (cross-language validation pattern)

Consistency: First suggested Run 21 (Medium), promoted to High in Run 22, maintained Run 23, 24

⚡ Medium Priority Suggestions

4. Benchmark Performance Tracker

5. API Breaking Change Detector

Purpose: Detect breaking changes in Z3's C API that could affect language bindings.

Problem Being Solved:

9 language bindings depend on stable C API
Breaking API changes can silently break bindings
Manual API compatibility checking is error-prone
Binding maintainers need advance notice of changes

Trigger: pull_request (when API files change)

Tools Needed:

GitHub API (toolsets: [default])
Bash for API diff analysis
Serena for code analysis

Safe Outputs:

add-comment: Report API changes on PRs

Value:
