Result, Option, error propagation, and custom error types.
Activate when:
For Result, Option, ? operator, custom error type patterns, and the thiserror/anyhow ecosystem crates, see references/error-handling.md.
This skill follows core:anti-fabrication. Every claim about Result/Option behavior,
the ? operator, and the thiserror/anyhow crate APIs is verified against the official
documentation and crates.io versions cited in sources.md — not inferred from generic
familiarity with the ecosystem. Before asserting an error-handling pattern or crate API this
skill and its references do not cover, check the installed crate version's docs.rs page
rather than guessing.
