Open-source terminal coding-agent harness published under Earendil Works, cited as the clearest working example of self-extending software via hooks and generated TypeScript extensions.
No evidence-backed relationships are recorded.
Pi Durable ports the Pi agent harness to TypeScript and checkpoints every step to one of three stores, so crashed agents resume where they stopped. Whether it can replace hand-built resume code depends on how it treats a tool call cut off mid-flight.
Reality
Portable Computer's harness is real engineering. The bill of materials starts at a $4,800 DGX Spark or a 24GB RTX card, which turns local agents into a hardware order.

A seven-part video walkthrough is packaging the Flask creator's Pi workflow for a general audience. The harness itself leaves isolation to the operator, and Earendil's own documentation says so plainly.

A frozen Claude Code session moved cleanly into seven rival agent formats. The approval and audit machinery wrapped around it moved into none of them.

A Cloudflare engineer argues web apps should let users generate their own missing features. The hard part is not the code generation, it is running that code beside live customer data.
