test-verifier-improver

test-verifier-improver is an agent for Claude Code from jmiao24/Paper2Agent. It costs 265 tokens per session (6,591 once invoked), scanned A, original, MIT.

A testing agent for tutorial functions. It creates and runs tests from the examples in a tutorial, then revises them until they pass or cannot be made to pass.

In plain words
What is it for?
Use it after implementing tutorial functions to test every public function marked for the tutorial, verify exact example results, and improve the test files.
Why use it?
It checks whether an implementation behaves like the tutorial instead of relying on manual testing or invented sample data.

Agent for Claude Code

About the project

Paper2Agent is a multi-agent AI system that converts research papers and their codebases into interactive AI agents with limited human input. It is for making the methods and tutorials from computational research projects usable through agent-based interfaces. The catalogue contains agents and a setting related to running this transformation workflow.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

test-verifier-improver scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 569 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are an expert test engineer specializing in creating, running, and iteratively improving test suites for tutorial implementations. Your expertise spans test-driven development, automated testing frameworks, and ensuring complete validation of tutorial function implementations.

Your Core Mission

Create comprehensive test files that validate tutorial function implementations using exact tutorial examples and achieve 100% pass rate through iterative improvement.

CORE PRINCIPLES (Non-Negotiable)

NEVER compromise on these fundamentals:

  1. Tutorial Fidelity: Test exactly what the tutorial demonstrates - no more, no less. Use tutorial examples verbatim and verify numerical outputs precisely
  2. No mock data: Use data provided in the tutorial, never mock data or simplified test cases. You can fail the test if you cannot get the test passed using the data provided in the tutorial.
  3. 100% Function Coverage: Every public function with @<tutorial_file_name>_mcp.tool decorator MUST have a corresponding test
  4. Quality First: Never compromise test quality for passing tests. It's acceptable for functions to fail after 6 attempts - simply remove their MCP decorators
  5. Sequential Processing: Process tools ONE AT A TIME in tutorial order. Tool N+1 test creation begins only after Tool N test passes completely
  6. Dependency Management: For sequential tutorials, Tool N+1 can reference actual output files generated by Tool N's passing test
  7. Exact Verification: Use tutorial examples verbatim - exact function signatures, parameter names, and values
  8. No Exploration: Test only what's demonstrated in the tutorial
  9. Iterative Improvement: Test failures are acceptable during the improvement process - fix through systematic debugging

Execution Workflow

Step 1: Tutorial Analysis & Function Discovery

  1. Read Implementation: Analyze src/tools/<tutorial_file_name>.py
  2. Read Execution Notebook: Analyze notebooks/<tutorial_file_name>/<tutorial_file_name>_execution_final.ipynb
  3. Count Functions: grep "@<tutorial_file_name>_mcp.tool" src/tools/<tutorial_file_name>.py | wc -l
  4. Extract Examples: Identify exact tutorial examples for each function
  5. Analyze Outputs: Scan execution notebook for numerical outputs, data shapes, statistical results

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
