autonomous-tdd-debugger

autonomous-tdd-debugger is a skill for Claude Code, Codex from roedyrustam/vibes-plug. It costs 46 tokens per session (963 once invoked), scanned A, original, MIT.

A development workflow that runs tests, reads the resulting error messages, and changes code in repeated cycles until the tests pass. TDD, or Test-Driven Development, means using tests to guide implementation.

In plain words
What is it for?
Use it to debug failing tests, fix bugs from terminal stack traces, and check that written code works by running the project's test command.
Why use it?
It removes the need to copy test failures or terminal errors back to the agent after each attempt. It helps investigate and fix failing tests without stopping after the first error.

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

autonomous-tdd-debugger 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 8d 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.

Autonomous TDD Debugger & Self-Healing Agent

English | Bahasa Indonesia


English

Orchestration & Integration

Connects and orchestrates with relevant domain skills like brainstorming, zero-to-prod-orchestrator, and project-context-mapper to ensure cohesive execution.

Description

This skill transforms the AI from a passive code generator into an active, autonomous engineer. When triggered, the agent is mandated to execute tests, read stack traces directly from the terminal, and modify code autonomously in a loop until all tests pass (Test-Driven Development) without asking the user to manually test.

Trigger Conditions

Activate this skill when the user asks to:

  • Fix failing tests or bugs without providing the error log.
  • "Write the code and ensure it works."
  • "Debug this completely autonomously."

Core Concepts

1. The Autonomous Proactive Loop
  1. Write/Modify Code: The agent modifies the application files.
  2. Execute: The agent uses run_command (e.g., npm run test, cargo test, pytest).
  3. Analyze: The agent reads the stdout/stderr from the background task.
  4. Heal Recursively: If it fails, do NOT stop and ask the user for help. The agent MUST parse the stack trace, identify the line number, apply a fix, and loop back to Step 2. Continue this cycle autonomously in the background.
  5. Report: Only when exit code 0 is achieved does the agent stop and report success to the user.
2. Agent Constraints
  • Zero-Human Intervention: Do NOT ask the user "Please run this and tell me the error." You are fully authorized and mandated to run it yourself iteratively until it works.
  • Avoid modifying the test files to make them pass unless the test itself is fundamentally flawed or outdated. Fix the implementation first.
  • If a terminal command hangs, use kill on the task and try again with a timeout.

Integration with Other Skills (MANDATORY)

  • e2e-testing-expert — Provides the exact testing frameworks (Vitest, Playwright) that this agent will execute.
  • error-resilience-expert — Helps the agent understand what architecture patterns to apply when fixing an error.
  • project-context-mapper — Allows the agent to find where the failing component is located in large codebases.

autonomous-tdd-debugger is a skill published in the GitHub repository roedyrustam/vibes-plug (49 stars, last pushed today), licensed MIT. It adds 46 tokens to every session and 963 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
