Package skills in Dart: giving AI agents the context to use a library
How Dart libraries distribute instructions for AI agents. An experiment with skills 1.0.1 examines installation, updates to locally edited copies and removal of instruction files.
ARKTELOS LAB / ENGINEERING LABORATORY
Not an opinion about technology, but engineering work that can be checked.
Dart and Flutter architecture, integrations, packages, AI agents, and experiments — with exact experiment revisions, explicit limitations, and reproducible evidence.

Articles and issues
Research articles are bound to immutable revisions and Evidence Signatures. Issues bring published work together in one contents page.
AI proposed a change. What did the user actually approve?
An assistant's proposal does not authorize a task update. A Dart experiment examines confirmation against displayed data, stale revisions, repeated requests and recorded operation outcomes.
The screen closed, but the operation did not: ownership of asynchronous work in Flutter
A route can disappear while its operation continues. A deterministic Flutter experiment separates UI delivery, source cancellation, operation ownership, and the handling of late values and errors.
Genkit Dart 0.16: when a tool result becomes part of the protocol
A reproducible comparison of the Genkit Dart 0.15.1 and 0.16.1 Tool contracts, including multipart responses, interrupts, Session boundaries, and the responsibilities that still belong to the application.
Error, state, and effect: three different contracts in a Flutter application
Separate an operation result, reproducible screen state, and a presentation effect; then choose delivery semantics before a rebuild or a new subscription chooses them by accident.
CODE / DATA / AGENTS
Experiments do not disappear behind conclusions
When a record relies on code, a benchmark, or an agent run, its environment, commands, results, and limitations are available from the article.
