gauntlet-curate

Night Market Skill — ported from claude-night-market/gauntlet. For the full experience with agents, hooks, and commands, install the Claude Code plugin.

Gauntlet Curate

Survey the DSA problem bank, identify coverage gaps, and propose new YAML entries for human review.

When This Skill Fires

Invoke this skill manually with Skill(gauntlet:gauntlet-curate) when the problem bank needs a coverage review. The skill is intended to participate in /update-plugins runs but is not yet wired into that command (see openpackage.yml registration). It is distinct from gauntlet:curate, which handles per-annotation knowledge capture and is what /gauntlet-curate invokes today.

Steps

1. Locate the problem bank at plugins/gauntlet/data/problems/. Read _manifest.yaml to load the expected NeetCode counts per category.

2. Survey current coverage by counting problems in each YAML file (skipping _manifest.yaml). Run the analysis script:

   cd plugins/gauntlet
   python scripts/curate_problems.py data/problems/ --output /tmp/gauntlet-curate-report.md
   

3. Identify gaps: categories whose actual count falls below the neetcode_count in the manifest. The script sorts gaps largest-first so the worst shortfalls appear at the top.

4. Review existing problems in each gap category to understand what is already covered before proposing additions.

5. Propose new YAML entries following the schema below. Add proposals to the report under "Proposed New Problems". Do NOT write proposals directly into data/problems/*.yaml.

6. Validate proposals by running:

   python -c "
   import yaml, sys
   sys.path.insert(0, 'src')
   from gauntlet.models import BankProblem
   proposals = yaml.safe_load(open('proposals.yaml'))
   for p in proposals:
       BankProblem.from_dict(p)
   print('All proposals valid.')
   "
   

7. Present the report to the human for review. The report includes the coverage table, gap list, and proposed entries. The human decides which proposals to merge into the YAML files.

Problem Schema

Each proposed entry must follow this schema:

- id: category-NNN
  title: Problem Title
  difficulty: easy       # easy | medium | hard | extra_hard
  prompt: |
    Problem statement with constraints and examples.
  hints:
    - First hint.
    - Second hint.
  solution_outline: |
    Approach and time/space complexity.
  tags: [tag1, tag2]
  neetcode_id: neetcode-NNN
  challenge_type: explain_why  # explain_why | multiple_choice | trace
                                # | code_complete | debug | rank

Required fields: id, title, difficulty, prompt. Optional fields default to empty values.

Safety Constraints

• Never modify files under data/problems/ directly.
• Never run with a --write or --fix flag: the script intentionally has none.
• All output is a proposal report for human approval.
• Existing hand-curated problems are never touched.

Output

A markdown report at the path specified by --output, containing:

• Coverage summary table (expected vs. actual per category)
• Gaps list sorted by missing count
• YAML schema template for new proposals
• Space for the human reviewer to add proposed entries

Human review is required before any YAML file changes.
