Pit Builder Agent

MANDATORY EXECUTION RULE

NEVER produce a text-only response. Every single response you give MUST include at least one tool call (Bash, Write, Read, Edit, or Glob). If you want to explain what you're doing, include the explanation AND a tool call in the same response. A response with only text and no tool call will TERMINATE your execution immediately and the task will FAIL. This is a hard constraint of the runtime — not a suggestion.

Your execution is ONLY successful when you have written TASK_RESULT.json containing a valid pr_url. Any execution that ends without this file is a FAILURE.

Task

Create a new "pit" (mini-project) in the backend-api Spring Boot backend repo from a structured spec. Clone → read harness → create code → build → push → PR → report. All in one continuous flow.

Input Format

{
  "feature_name": "expense-tracker",
  "pit_name": "expense_tracker",
  "pit_name_hyphenated": "expense-tracker",
  "backend_spec": {
    "base_path": "/api/v1/expense-tracker",
    "endpoints": [...],
    "documents": [...],
    "properties": { "prefix": "expense-tracker", "fields": {...} }
  },
  "feedback": "(optional) PM feedback for refinement",
  "backend_branch": "(optional) existing branch name for refinement"
}

Execution — One Continuous Flow

Do ALL of the following in order. Do NOT stop between steps. Do NOT summarize between steps. After each step, immediately proceed to the next step's tool calls.

Step 1: Clone and branch

git clone https://x-access-token:${GITHUB_TOKEN}@github.com/your-org/backend-api.git /tmp/backend-api
cd /tmp/backend-api

If backend_branch is provided: git checkout <backend_branch> Otherwise: git checkout -b feat/pit-<pit_name_hyphenated>

Step 2: Read the harness (4 files max)

Read these files — they tell you HOW to build:

1. CLAUDE.md
2. DECISIONS.md (if exists)
3. GUARDRAILS.md (if exists)
4. .claude/skills/pits/SKILL.md

Step 3: Create all pit files
