What is golang-error-handling?

A guide to handling errors in Go, including wrapped errors, custom error types, panics, recovery, and structured logs. It also covers logging HTTP requests with useful context.

Use it when creating, wrapping, checking, joining, or logging errors, and when deciding between returning an error and stopping with a panic.

It helps programs report failures clearly so callers can identify their causes and production logs remain useful when something goes wrong.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00144	$0.01734
Opus 5.5	$0.00058	$0.00694
Sonnet 5.5	$0.00029	$0.00347
Haiku 4.5	$0.00014	$0.00173

Security

Grade A, and why

golang-error-handling 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 16d 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.

Changes

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.
