Coding Agent

Coding Agent

Delegate coding work to Claude Code via the code_agent tool. You are the orchestrator — describe the task, let the coding agent execute.

When to Use

• Building new features, handlers, or scripts
• Refactoring or restructuring code across multiple files
• Creating new skills with scripts/
• Reviewing PRs or analyzing codebases
• Any task that requires reading multiple files, writing code, and running tests
• Installing dependencies (npm install, bun add)
• Running tests (bun test)

When NOT to Use

• Simple file reads/edits -> use workspace tools
• Config changes -> use config_update
• Quick shell commands (git, curl) -> use run_command

How to Use

Basic Task

code_agent(
  task: "Build a health-check handler in src/scheduler/handlers/health-check.ts that pings an endpoint every 30 seconds and alerts the user if it returns non-200.",
  effort: "low"
)

Effort Levels

| Effort | Model | Best for | |--------|-------|----------| | low (default) | Claude Sonnet | Single-file edits, small fixes, tests, config changes | | high | Claude Opus | Multi-file features, complex refactors, deep debugging |

Good Task Descriptions

Be specific. Include:

1. What to build (feature, handler, script)
2. Where to put it (file path)
3. Pattern to follow (reference existing code)
4. How to test (run tests, verify output)

Good: > "Create a TypeScript job handler in src/scheduler/handlers/health-check.ts that polls https://example.com/health every 30 seconds. If non-200, return the error as the job result. Follow the JobHandler pattern from existing handlers. Include error handling."

Bad: > "Build me a health checker"

Platform-Specific Patterns

Creating a New Handler (auto-loaded)

Handlers in src/scheduler/handlers/ are hot-reloaded. The coding agent should:

1. Read an existing handler as a reference
2. Create a new handler file implementing the JobHandler interface
3. Export it as a named export
4. The job-worker picks it up automatically — no restart needed

Creating a New Skill

Skills in skills/ are also hot-loaded. The coding agent should:

1. Read skills/skill-creator/SKILL.md for the format
2. Create skills//SKILL.md with YAML frontmatter
3. Optionally add scripts/, references/, assets/ subdirectories
4. The skill loader picks it up within 30 seconds

Rules

1. You are the orchestrator — do NOT hand-code patches yourself. Delegate to code_agent.
2. If the agent fails — explain what went wrong. Do not silently take over and write the code yourself.
3. Be patient — coding tasks take 10-120 seconds. Wait for the result.
4. Report back — after code_agent finishes, summarize what was built and whether it needs a restart.
5. Working directory matters — always set cwd to the project root so the agent has full context.
