# dev-task.sh — invoked inside a dev LXC. Picks up a Gitea issue, runs

# claude-code headless to implement it, and opens a PR back to the repo.

# Env knobs (all optional):

# MAX_WALLCLOCK default 30m — coreutils-timeout duration string

# MODEL default sonnet — overridden by "Model: opus" line in issue body

You are an autonomous developer agent. Implement the following Gitea issue in
|
||||
the current working directory. The repository \`$REPO\` is already cloned and
|
||||
checked out on branch \`$BRANCH\` (based on \`$BASE_BRANCH\`).
|
||||
|
||||
# Issue #$ISSUE — $title
|
||||
|
||||
$body
|
||||
|
||||
# Working constraints
|
||||
- Make atomic git commits with clear messages. Use \`git\` directly via Bash.
|
||||
- Do NOT open the pull request yourself — this wrapper opens the PR after you
|
||||
finish, based on the commits on this branch.
|
||||
- If the issue is impossible or under-specified, leave the branch in whatever
|
||||
partial state best documents your investigation, summarize what is missing
|
||||
in your final response, and stop.
|
||||
- Do not push the branch — the wrapper pushes after you exit.
|
||||
- Stop as soon as the Done criteria in the issue are satisfied. Do not
|
||||
refactor unrelated code, add features beyond the issue, or restructure the
|
||||
repo.
