Error Handling

Runtime package errors should use the SDK error hierarchy rooted at @alchemy/common BaseError.

Rules

RuleWhen to read
BaseErrorBefore adding package runtime errors.
No plain ErrorBefore writing throw statements in packages/.
Raise footgunBefore using or modifying raise.

Evidence

  • packages/common/src/errors/BaseError.ts extends viem's BaseError.
  • .eslintrc forbids throw new Error(...) in packages/**/* except tests.
  • .eslintrc forbids import { BaseError } from "viem" to prevent accidentally using viem's BaseError instead of @alchemy/common's.
  • packages/wallet-apis/src/utils/schema.ts wraps Zod validation failures in @alchemy/common BaseError.

    How matches are found. Word for word: the exact same text. Edited: shares passages with this file (“99% same” means 99% of its five-word phrases also appear here; 10% or more counts). Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.

      resilience

      Apply resilience patterns (retry, backoff, circuit breaking) when writing or reviewing code that makes outbound HTTP/REST calls, database operations, or any I/O that can experience transient failures. Use this skill when: (1) writing new code that calls external services or APIs, (2) reviewing code that uses fetch, HTTP clients, or service-to-service calls, (3) adding queue consumers or workers that interact with remote systems, (4) debugging intermittent failures in production.

Does it work?

Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

No reviews yet

People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.

  • It worked
  • Partly
  • It didn't
What did you use it for? e.g. Reviewing pull requests in a Rails app

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.

Your trail

Files you open will collect here, so you can find them again.

Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.

Now do this for your own.

Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
