Harness Starter: Coding
A coding-assistant starter. Produces a unified-diff file as its primary
deliverable plus a preview artifact listing the changed files. Copy this
crate when you want to build an app that ships a patch/diff/changeset.
What this starter demonstrates
primary = "patches/*.diff" — the canonical deliverable.preview = "patches/*.files.txt" — a secondary artifact the operator
surface may use to summarize the change.file_size_min:$primary:64 — validator rejects empty patches.- Multi-artifact spawn task binding (
artifacts = ["primary", "preview"])
so the runtime delivers both files.
See docs/OCTOS_HARNESS_DEVELOPER_GUIDE.md for the full contract.
Tools
propose_patch
Render a patch as a unified-diff file plus a preview file list.
{
"title": "Fix typo in hello",
"hunks": [
{
"file": "src/lib.rs",
"new_content": "pub fn hello() -> &'static str {\n \"hi\"\n}\n"
}
]
}
Parameters:
title (required): short title; derives the filename
(patches/fix-typo-in-hello.diff).hunks (required, non-empty): list of {file, new_content} hunks. Each
hunk becomes a full-file replacement hunk in the diff.
Artifacts:
patches/<slug>.diff — primary unified-diff file.patches/<slug>.files.txt — preview list of changed files.
Replace this stub
The starter generates full-file replacement hunks. A real coding assistant
should use similar or diff to compute minimized unified diffs, and
consider running the patch through git apply --check in a validator
before delivery.
