Propose new criteria for the task implementation rubric. This is typically invoked after /review-task identifies general patterns that should be caught for all future tasks.

Run this from within your local clone of the benchmark repo.

Step 1: Read Current Rubric

Detect the repo root and read the current rubric to understand the format:

REPO_ROOT=$(git rev-parse --show-toplevel)
cat "$REPO_ROOT/rubrics/task-implementation.toml"

Each criterion follows this TOML format:

[[criteria]]
name = "criterion_name"
description = "One-line description"
guidance = """
Multi-line guidance explaining what to check.

PASS if ... FAIL if ..."""

Step 2: Accept Criteria Descriptions

Parse $ARGUMENTS for the criteria to add. If invoked from /review-task, the rubric improvement candidates will be described in the review summary. If invoked standalone, the user provides a description of what to add.

For each candidate, draft a new [[criteria]] entry matching the existing format:

• name: snake_case, concise
• description: one-line summary
• guidance: detailed explanation with PASS/FAIL conditions

Present the drafted criteria to the user for review before proceeding.

Step 3: Create Branch and Apply Changes

Detect the GitHub remote and create a branch:

REPO_ROOT=$(git rev-parse --show-toplevel)
GITHUB_REPO=$(git remote get-url origin | sed 's|.*github.com[:/]\(.*\)\.git$|\1|; s|.*github.com[:/]\(.*\)$|\1|')
BRANCH="rubric/add-criteria-$(date +%Y%m%d)"

cd "$REPO_ROOT"
git checkout -b "$BRANCH"

Append the new [[criteria]] entries to rubrics/task-implementation.toml.

Step 4: Commit, Push, and Create PR

cd "$REPO_ROOT"
git add rubrics/task-implementation.toml
git commit -m "Add rubric criteria: <brief description>"
git push -u origin "$BRANCH"
gh pr create --repo "$GITHUB_REPO" \
  --title "Add rubric criteria: <brief description>" \
  --body "$(cat <<'EOF'
## Summary
- Adds new criteria to `rubrics/task-implementation.toml` based on patterns observed during task review

## New Criteria
<list each new criterion name and one-line description>

## Motivation
<which review or PR prompted this, what pattern was observed>

## Test plan
- [ ] Run `harbor check` against existing tasks to verify new criteria don't cause false positives
- [ ] Verify TOML syntax is valid

Open the PR URL in the browser and report it to the user.

Step 5: Propagate to Downstream Repos (remind user)

After the PR is merged, remind the user to propagate to downstream repos:

git fetch template
git merge template/main
git push origin main

And switch back to the main branch:

git checkout main
git branch -d "$BRANCH"
