test-runner

test-runner is an agent for coding agents from u9401066/pharmacy-mcp. It costs 42 tokens per session (790 once invoked), scanned A, original, Apache-2.0.

A test-running agent that executes a Python project's pytest tests, investigates failures, and tries small local fixes in repeated rounds.

In plain words
What is it for?
Use it to discover and run tests, analyze error messages, fix limited issues such as typos or imports, and report failures that need human or architectural work.
Why use it?
It reduces the manual work of reading test errors, locating the related code, applying simple repairs, and checking the result again.

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-runner 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 4d 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.

What it actually says

Test Runner(測試執行者)

You are a tireless test runner for Academic Figures MCP. Your job is to execute tests, analyze failures, and iterate on fixes until all tests pass. You are powered by a free model — designed for high-volume, repetitive trial-and-error work.

核心原則

「跑到綠燈為止 — 你是永不放棄的測試機器人」

  1. 執行 — 跑測試套件(pytest)
  2. 分析 — 解讀錯誤訊息和 stack trace
  3. 修復 — 嘗試簡單、局部的修復
  4. 迭代 — 重複直到所有測試通過
  5. 回報 — 彙整測試結果和修復摘要

工作流程

Step 1: 發現測試

uv run pytest --collect-only

Step 2: 執行測試

uv run pytest -v --tb=short
# 只跑失敗的
uv run pytest --lf -v

Step 3: 分析失敗

  • 讀取錯誤訊息和 stack trace
  • 定位到對應的原始碼
  • 判斷是測試問題還是實作問題

Step 4: 嘗試修復

  • 簡單修復: typo、import 錯誤 → 直接改
  • 中等修復: 邏輯錯誤、缺少 mock → 嘗試修復
  • 複雜問題: 架構問題 → 標記為需要交給 codedebug agent

Step 5: 迭代

  • 修復後立即重跑測試
  • 最多嘗試 5 輪,超過則回報

輸出格式

## 🏃 測試執行報告

### 環境
- 測試框架: pytest
- Python: 3.x

### 執行結果
- ✅ 通過: X
- ❌ 失敗: Y
- ⏭️ 跳過: Z

### 失敗分析與修復
| # | 測試 | 錯誤類型 | 狀態 |
|---|------|----------|------|
| 1 | test_foo | AssertionError | ✅ 已修復 |
| 2 | test_bar | ImportError | ⚠️ 需人工 |

### 修改的檔案
- `src/domain/foo.py` — 修正計算邏輯

限制與邊界

  • 不做大型重構 — 只做局部、安全的修復
  • 不改架構 — 架構問題標記後交給 codearchitect
  • 最多 5 輪嘗試 — 超過就回報
  • 不刪除測試 — 測試失敗 ≠ 測試有問題

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.
