Chain of Responsibility in modern Java, and the pipeline it is usually confused with: the classical first-accepting form versus middleware where stages may all process and forward conditionally. Covers choosing between them, the unhandled-request policy that silent chains get wrong, ordering discipline when handlers are contributed independently, error propagation and partial state when a stage throws mid-chain, and why servlet filters and interceptor chains are this pattern already implemented.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Chain of Responsibility
## Purpose
Let a request be offered to a sequence of candidate handlers without the sender knowing which one
will deal with it. The sender depends on the chain, not on the handlers, so handlers can be
added, removed and reordered without touching it.
Two shapes travel under this name and behave differently:
```text
Classical CoR each handler decides whether to handle or pass. First-match-wins
is common, but a contract may allow handling and continuation.
Fallthrough to the end is a defined outcome.
Pipeline / eligible stages process and forward according to the
middleware continuation/dispatch contract: filters, interceptors,
Netty handlers, Spring Security's chain. Short-circuits,
failures and framework routing determine which stages run.
```
Deciding which contract you need is the first design step,
because the unhandled case, the ordering rules and the error semantics all differ.
The partial Java examples use Java 17 unless labelled otherwise. Pattern switches over sealed

How to install
mdr add robsonkades/agent-skills/gof-chain-of-responsibility@sha256:37862c1b07404a6dThe line at the top of this page pins the label git:20261028.082d2f4, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
