GitHub Repository Research Prompt

GitHub Repository Research Prompt

You are analyzing a GitHub repository as a software architect and systems researcher.

Critical rules

  1. Do not assume technologies or patterns based on the repo name, description, or my prior comments.
    • Instead, infer everything from:
      • README*, docs/, pyproject.toml / package.json, Dockerfile*, compose*, etc.
  2. Separate facts from inferences:
    • Mark things as:
      • [Grounded] – directly supported by files you’ve inspected.
      • [Inference] – reasoned from patterns, but not explicitly stated.
  3. If a part of this prompt refers to a technology (e.g., “Temporal”, “Logfire”, “MCP”, “GraphRAG”) that you do not find in the repo:
    • Treat that as a hypothesis to test, not as a fact.
    • Say explicitly: “No evidence of X found in the repo.”

You may request additional files / paths if needed.


Step 0 — Initial Context Gathering

  1. Read:

    • Root README*
    • pyproject.toml / package.json / requirements.txt / Pipfile / Cargo.toml, etc.
    • Any top-level docs/ or examples/ directory.
  2. From these, build a high-level summary:

    • Problem/domain the repo targets.
    • Intended users (library authors, app devs, data scientists, operators, etc.).
    • Claimed key features.

Mark each bullet as [Grounded] or [Inference].


Step 1 — Repository Map

Create a structured map of the repo:

  1. List all top-level directories and key files and describe their purpose:
    • e.g., api/, frontend/, examples/, infra/, scripts/, etc.
  2. For each major subproject or example:
    • What does it appear to do?
    • How is it invoked (CLI, HTTP API, library import, etc.)?

Flag where you are inferring behavior from naming vs. confirmed usage in code.


Step 2 — Stack & Dependencies

From configuration and code:

  1. Identify the primary languages and frameworks used:
    • e.g., Python + FastAPI, TypeScript + React, Rust + Axum, etc.
  2. Identify major runtime dependencies, such as:
    • Web frameworks
    • Agent/orchestration frameworks
    • Observability / tracing libraries
    • Databases / message queues
    • LLM / AI providers

For each major dependency, answer:

  • Where in the code is it used?
  • What role does it play (HTTP server, agent runtime, storage, tracing, etc.)?

If the repo mentions a technology by name but you don’t see it in code, call that out explicitly.


Step 3 — Architectural Deep Dive

For each significant component (service, example app, module):

  1. Describe its responsibility and entrypoints:

    • HTTP endpoints
    • CLI commands
    • Library APIs
    • Background workers / schedulers
  2. For at least one representative flow per component, document the data path:

    • Inputs → validation → processing → external calls (DB, LLM, APIs) → outputs.
    • Where, if anywhere, types or schemas enforce constraints.
  3. Build a conceptual architecture diagram (textual):

    • Components as nodes
    • Edges as calls (HTTP, gRPC, DB queries, message bus, function calls)
    • Label any external systems (DBs, queues, LLMs).

Keep a clear distinction between:

  • What is explicitly present in the code.
  • What you infer from conventions.

Step 4 — Runtime & Operational Model

Analyze the repo for runtime/ops concerns:

  1. Configuration & secrets

    • How are things configured? (env vars, config files, flags)
    • Any clear patterns for environment separation (dev/stage/prod)?
  2. State & persistence

    • What persistence layers exist (files, relational DB, KV store, etc.)?
    • How does the code handle migrations or schema definition, if at all?
  3. Durability / execution model

    • Do you see explicit integration with:
      • Workflow engines (Temporal, DBOS, Airflow, etc.)?
      • Message queues or schedulers?
    • If yes:
      • How are workflows / jobs defined?
      • How is state recovered after failure?
    • If no:
      • Describe the default failure behavior (what happens if a process crashes mid-flow?).

Only mention specific technologies (e.g., “Temporal”) if they show up in code or config.


Step 5 — Integration Points (APIs, Tools, External Systems)

Identify all external-facing interfaces:

  1. APIs:

    • HTTP endpoints and their payload shapes.
    • Any OpenAPI / schema docs.
  2. Tooling / protocol integration (if present):

    • MCP, gRPC, WebSocket, CLI, plugin systems, etc.
    • For each, summarize how the repo defines and consumes these interfaces.
  3. LLM / AI Integration (if present):

    • Which providers / models?
    • How requests and responses are structured.
    • Any validation or safety-related controls.

If a concept like “MCP” or “GraphRAG” does not appear in the codebase, explicitly say so.


Step 6 — Design Patterns, Anti-Patterns, Extensibility

From the code and structure:

  1. Identify recurring design patterns, such as:

    • Dependency injection
    • Layered architecture
    • Ports-and-adapters / hexagonal boundaries
    • Event-driven or workflow patterns
    • Strong typing & validation boundaries
  2. Identify potential anti-patterns or risks:

    • Tight coupling between layers
    • Inconsistent error handling
    • Mixed concerns (business logic in handlers, etc.)
    • Weak separation between core logic and I/O
  3. Evaluate extensibility:

    • Where would you add:
      • New endpoints
      • New agents / workflows
      • New storage backends
    • How painful would that be, based on the current design?

Back each point with code references where possible.


Step 7 — Application to My Context (Optional Layer)

Given everything above, propose:

  1. How this repo’s patterns could be integrated into:

    • Agent-based systems
    • RAG / knowledge-graph systems
    • Multi-service architectures with observability
  2. Concrete extension ideas:

    • Where to plug in additional retrieval or graph layers
    • How to add more robust observability or evaluation pipelines

Tie recommendations to actual extension points in the code (files, classes, functions).


Output Format

Produce your analysis with these sections:

  1. Executive Summary (1–2 paragraphs)
  2. Repository Map
  3. Stack & Dependencies
  4. Architectural Deep Dive
  5. Runtime & Operational Model
  6. Integration Points
  7. Design Patterns / Anti-Patterns / Extensibility
  8. Recommendations for Integration / Extension
  9. Open Questions & Uncertainties (things the repo doesn’t clearly answer)

For each major claim, note [Grounded] or [Inference].
