honeybadger-errors

A set of rules for reporting application errors to Honeybadger, an error-monitoring service.

In plain words
What is it for?
Use it when adding Honeybadger notifications, classifying API or database failures, and attaching details such as users, orders, or retry attempts.
Why use it?
It makes errors easier to group and investigate by requiring descriptive categories and useful information about the failed operation.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Made for: Cursor.

Per session 8 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 500 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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

honeybadger-errors 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 2d 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.

Honeybadger Error Tracking

Standard Pattern

from honeybadger import honeybadger

honeybadger.notify(
    exception,
    error_class="DescriptiveErrorCategory",
    context={
        "operation": "what_was_being_attempted",
        "user_id": user.id,
        "item_id": item.id,
    }
)

Error Classification

Use meaningful error_class values for grouping:

General Categories

  • APIError - External API failures
  • ValidationError - Input validation failures
  • DatabaseError - Database operation failures
  • ConfigurationError - Missing or invalid configuration
  • AuthenticationError - Auth/permission failures

Specific When Needed

For high-volume errors, use vendor-specific classes:

  • StripeAPIError - Stripe API failures
  • AWSServiceError - AWS service failures
  • RedisConnectionError - Redis connection issues

Context Best Practices

Always Include

context = {
    "operation": "what_was_being_attempted",
    "retry_attempt": 1,
    "user_input": relevant_input_data,
}

Use Human-Friendly Identifiers

We use email addresses and names, not database IDs:

context = {
    "user_email": user.email,
    "order_number": order.number,
}

What to Avoid

We don't use tags (use context instead). We avoid generic error classes (Error, Exception), sensitive data (API keys, passwords), and redundant info.

Implementation Example

try:
    result = external_api.call()
except APIException as e:
    honeybadger.notify(
        e,
        error_class="ExternalAPIError",
        context={
            "api": "stripe",
            "operation": "create_payment",
            "customer_id": customer.id,
            "amount": str(amount),
            "status_code": getattr(e, 'status_code', None),
        }
    )
    raise

Error Class Naming

We use PascalCase ending with Error. We're specific enough to group similar issues, but general enough to avoid too many unique classes. We use the same error class for the same failure type across the codebase, and we check existing error classes before creating new ones.

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.

honeybadger-errors is a cursor rule published in the GitHub repository TechNickAI/ai-coding-config (24 stars, last pushed 2mo ago), licensed MIT. It adds 8 tokens to every session and 500 once invoked, about $0.0000 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.
