ambassador-pattern SKILL.md skillA

ambassador-pattern from robsonkades/agent-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add robsonkades/agent-skills/ambassador-pattern@git:20261016.c769bd8

Pins git:20261016.c769bd8 in mdr.lock. Pin the fingerprint instead.

Choose or review a local outbound proxy when discovery or routing changes require client releases, a canary or shadow needs routing outside the app, or retries overlap across app, proxy and mesh. Define the listener, policy ownership, deadlines and failure behavior. Covers shard-map consumption and experiment routing, not shard algorithms (sharding-and-partitioning), container lifecycle (sidecar-pattern), or output normalization (adapter-sidecar-pattern).

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

# Ambassador Pattern

## Purpose and boundary

An ambassador mediates the application's outbound calls through a local peer process.
The app can delegate topology and transport policy, but still owns business intent and
observes latency, errors and deadlines. This skill covers that delegation, not ingress
gateways or the Ambassador-branded product. Pod mechanics belong to `sidecar-pattern`.

Policy can change independently of application code **if** the selected proxy supports
the required configuration updates. Hot reload, proxy replacement and a pod rollout have
different restart consequences; name the actual update mechanism before promising no restart.

## Workflow

1. **Establish the evidence.** Inspect available client code, deployment/configuration,
   tests and prior decisions before requesting missing evidence. Obtain the outbound call path,
   protocols on both hops, connection/stream lifetimes, proxy/mesh and client versions,
   effective routes and retry settings, deadline semantics,
   upstream operation contracts, replica count and relevant latency/load limits. For a
   diagnosis, request correlated app/proxy/upstream traces, attempt counts and queue metrics.

How to install

The exact contents, by fingerprint
mdr add robsonkades/agent-skills/ambassador-pattern@sha256:5a15ec7d984f1b28

The line at the top of this page pins the label git:20261016.c769bd8, 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.
