# The replay portfolio — five real Reelier skills

Five real, read-only skills against live public APIs — no accounts, no keys, no writes. Each run is a deterministic replay (same HTTP calls, same assertions, zero LLM tokens) and writes a receipt saying exactly which assertions held. All five were replayed for real with the published CLI on 2026-07-21; step and assertion counts below are parsed from the skill files themselves, never hand-typed.

## Skills

## The standing public proof

A GitHub Action replays all five every 6 hours (plus on demand); the public Actions tab is the standing audit log: https://github.com/seldonframe/reelier/actions/workflows/portfolio-replay.yml. A failing endpoint produces an honestly failing receipt, never a retried-until-green one. Source files: https://github.com/seldonframe/reelier/tree/main/examples/portfolio
