File a GitHub issue

Before drafting, read AGENTS.md and:

Issue Kinds and Body Structure

Pick the smallest matching structure.

Kind	When to use	Labels
bug	A bug or regression was found	bug, agent-generated
task	An improvement, refactor, or feature request	agent-generated + priority if known
experiment	An experiment needs tracking	experiment, agent-generated

Bug body

<what is broken and its impact -- concrete symptoms or error messages>

Reproduce:
1. <step>
2. <step>

Expected: <what should happen instead>

<optional: concise evidence or confirmed root cause>

Task body

<what needs to be done and why -- enough context for anyone on the team>

Done when:
<specific, testable completion criteria>

Experiment body

## TL;DR

<One-paragraph current summary. Leave blank only when the work is just being kicked off.>

## Description

<Context someone outside the thread can understand.>

## Hypothesis or Goal

<What are you trying to learn, fix, or achieve?>

## Status

<Current state; update as evidence lands.>

Workflow

1. Gather and classify

Extract the symptom or desired outcome, impact, location, reproduction, known cause, and severity. Ask when the issue or its kind is ambiguous.

2. Check duplicates

Search for existing issues first:

gh issue list --repo marin-community/marin --state open --search "<keyword>"

If a match exists, tell the user and offer to comment on it instead.

3. Draft

Title: At most 80 characters, optionally prefixed with a scope tag. State a factual symptom for a bug (e.g. [levanter] Gradient accumulation drops the last microbatch) and an imperative outcome for a task (e.g. [levanter] Handle partial accumulation steps). Do not add bug:, task:, or another type prefix.

Use the body structure above. Keep the facts needed to act; link code with file:line, trim errors to relevant frames, and omit filler, repeated titles, diff inventories, and unnecessary implementation narration. Bugs need numbered reproduction steps; tasks need testable completion criteria.

4. Inspect the payload

Apply the writing-style final compression pass to the exact title and body that will be sent to GitHub. For a bug or task, verify the title is at most 80 characters. Every remaining sentence must add a symptom, impact, reproduction step, observation, expected behavior, or completion criterion.

5. Apply the approval boundary

If the user explicitly asked to file an issue, skip the preview — file it and share the link. If the agent surfaced the issue (not explicitly requested), show the drafted title and body and wait for approval or edits.

6. File the issue

Write the body to a uniquely named temp file, then pass it with --body-file. Do not inline the body with shell substitution (--body "$(cat <<'EOF' ...)") — multiline text can be corrupted by pasted output or escaping mistakes. Do not reuse a fixed path like /tmp/issue-body.md; concurrent agent runs can overwrite each other's drafts on shared hosts.

body_file="$(mktemp "${TMPDIR:-/tmp}/issue-body.XXXXXX.md")"
trap 'rm -f "$body_file"' EXIT

cat > "$body_file" <<'EOF'
<body>
EOF

issue_url="$(gh issue create --repo marin-community/marin \
  --title "<title>" \
  --label "agent-generated" \
  --body-file "$body_file")"

Add kind-appropriate labels (bug, experiment). If a relevant label does not exist, skip it rather than creating new labels. For task issues, add a priority label (p1, p2, p3) if the user specifies one or severity is clear.

Before creating the issue, re-open the body file and verify it contains no unrelated shell output (pre-commit logs, pytest session headers, prompt transcripts). If it does, clean the draft before posting.

After creating the issue, fetch its published text with gh issue view "$issue_url" --json title,body and correct any text added or altered by the publishing tool.

7. Report

Print the issue URL.
