### Validating API Key Format (OpenAI Example)

Source: https://github.com/pinchbench/skill/blob/main/tasks/task_byok_best_practices.md

Provides a basic function to validate the format of an API key, using OpenAI's key format as an example. This is a preliminary check before attempting to use the key.

```python
import re

def is_valid_openai_key(api_key):
    # OpenAI API keys are typically 51 characters long and start with 'sk-'
    # This is a basic format check, not a guarantee the key is active.
    if not isinstance(api_key, str):
        return False
    return re.match(r'^sk-[a-zA-Z0-9]{48}$', api_key) is not None

# Example usage:
# test_key_valid = "sk-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
# test_key_invalid = "invalid-key"
# print(f"'{test_key_valid}' is valid: {is_valid_openai_key(test_key_valid)}")
# print(f"'{test_key_invalid}' is valid: {is_valid_openai_key(test_key_invalid)}")
```

### Initialize Express Server and Connect Database

Source: https://github.com/pinchbench/skill/blob/main/tasks/task_readme_generation.md

Sets up the Express application, defines API routes, and establishes a database connection. Ensure environment variables are configured for port and database access.

```typescript
import express from 'express';
import { config } from './config';
import { authRouter } from './routes/auth';
import { tasksRouter } from './routes/tasks';
import { webhookRouter } from './routes/webhooks';
import { connectDb } from './db';
import { logger } from './utils/logger';

const app = express();

app.use(express.json());
app.use('/api/auth', authRouter);
app.use('/api/tasks', tasksRouter);
app.use('/api/webhooks', webhookRouter);

app.get('/health', (_req, res) => res.json({ status: 'ok' }));

async function main() {
  await connectDb();
  app.listen(config.port, () => {
    logger.info(`TaskFlow API listening on port ${config.port}`);
  });
}

main().catch((err) => {
  logger.error('Failed to start server', err);
  process.exit(1);
});
```

--------------------------------

### Run Full Benchmark Suite

Source: https://context7.com/pinchbench/skill/llms.txt

Execute the entire PinchBench suite against a specified model via OpenRouter. Requires setting the OPENROUTER_API_KEY environment variable.

```bash
# Run the full suite against Claude Sonnet 4 via OpenRouter
export OPENROUTER_API_KEY=sk-or-...
./scripts/run.sh --model openrouter/anthropic/claude-sonnet-4
```

```

--------------------------------

### Clone and Run PinchBench

Source: https://github.com/pinchbench/skill/blob/main/README.md

Clone the repository and run benchmarks with a specified model. Model IDs require a provider prefix.

```bash
# Clone the skill
git clone https://github.com/pinchbench/skill.git
cd skill

# Run benchmarks with your model of choice
./scripts/run.sh --model openrouter/anthropic/claude-sonnet-4

# Or run specific tasks
./scripts/run.sh --model openrouter/openai/gpt-4o --suite task_calendar,task_stock
```

--------------------------------

### Load All Tasks with TaskLoader

Source: https://context7.com/pinchbench/skill/llms.txt

Initialize TaskLoader and load all tasks from the 'tasks/' directory. Uses manifest.yaml if present, otherwise falls back to glob-based discovery.

```python
from pathlib import Path
from lib_tasks import TaskLoader, Task

loader = TaskLoader(Path("tasks"))

# Load all tasks (uses manifest.yaml if present, else alphabetical glob)
tasks = loader.load_all_tasks()
print(f"Loaded {len(tasks)} tasks")
# Loaded 53 tasks

# Category and core-task metadata populated after manifest load
print(loader.categories)           # ['productivity', 'research', 'coding', ...]
print(loader.category_map)         # {'task_calendar': 'productivity', ...}
print(loader.core_tasks)           # ['task_sanity', 'task_calendar', ...]
```

--------------------------------

### Apache Error Log Format Example

Source: https://github.com/pinchbench/skill/blob/main/assets/logs/README.md

Example of a line from an Apache web server error log, including timestamp, log level, and message.

```text

--------------------------------

### Register and Submit Results

Source: https://github.com/pinchbench/skill/blob/main/README.md

Register for an API token and run benchmarks; results are automatically uploaded. Use --no-upload for local results only.

```bash
# Register for an API token (one-time)
./scripts/run.sh --register

# Run benchmark — results auto-upload with your token
./scripts/run.sh --model openrouter/anthropic/claude-sonnet-4
```

--------------------------------

### Run Benchmark and Auto-Upload Results

Source: https://context7.com/pinchbench/skill/llms.txt

Execute a benchmark run after registration. Results are automatically uploaded to the PinchBench leaderboard using the saved API token. Provides a submission ID and a view URL upon successful upload.

```bash
# Step 2: Run benchmark — results are auto-uploaded with your token
./scripts/run.sh --model openrouter/anthropic/claude-sonnet-4
# Output: Submission ID: abc123 | View at: https://pinchbench.com/...
```

--------------------------------

### Get All Tasks

Source: https://github.com/pinchbench/skill/blob/main/tasks/task_readme_generation.md

Retrieves all tasks associated with the authenticated user. Requires the user to be authenticated via the 'authenticate' middleware.

```typescript
import { Router } from 'express';
import { db } from '../db';
import { authenticate } from '../middleware/auth';

export const tasksRouter = Router();
tasksRouter.use(authenticate);

tasksRouter.get('/', async (req, res) => {
  const tasks = await db.task.findMany({ where: { userId: req.userId } });
  res.json(tasks);
});
```
