Create a new Bottlerocket settings model with SettingsModel trait implementation
Creates a complete settings model package with proper directory structure, dependencies, and SettingsModel trait implementation.
You (reading this file) are the orchestrator.
| Role | Reads | Does |
|---|---|---|
| Orchestrator (you) | SKILL.md, next-step.py output | Runs state machine, spawns subagents, writes outputs |
| State machine | progress.json, workspace files | Decides next action, validates gates |
| Subagent | Phase file (e.g., SCAFFOLD.md) | Executes phase instructions |
⚠️ You do NOT read files in phases/ — pass them to subagents via context_files. Subagents read their phase file and execute it.
workspace = f"planning/{model_name}-settings"
bash(f"mkdir -p {workspace}", on_error="raise")
write("create", f"{workspace}/input.txt", file_text=f"Model name: {model_name}
Description: {description}")
while True:
action = bash(f"python3 skills/create-settings-model/next-step.py {workspace}", on_error="raise")
a = json.loads(action)
if a["type"] == "done":
final = fs_read("Line", f"{workspace}/FINAL.md", 1, 1000)
break
if a["type"] == "gate_failed":
log(f"Gate failed: {a['reason']}")
break
if a["type"] == "spawn":
r = spawn(
a["prompt"],
context_files=a["context_files"],
context_data=a.get("context_data"),
allow_tools=True
)
write("create", f"{workspace}/{a['output_file']}", file_text=r.response)
The state machine handles the happy path. When things go wrong, exercise judgment:
| Exception | Response |
|---|---|
| Spawn times out | Assess: retry with longer timeout? Report partial progress? |
| Spawn returns error | Report failure to state machine, let it track retries |
| Empty/invalid response | Treat as failure, report to state machine |
Don't silently advance past failures. Either retry, fail explicitly, or document gaps.
| ❌ Don't | ✅ Do |
|---|---|
| Read phase files yourself | Pass phase files via context_files to subagents |
| Decide what phase is next | State machine decides via next-step.py |
| Skip gates "because it looks done" | Always validate gates |
| Store state in your memory | State lives in progress.json |
| Silently advance past failures | Retry, fail, or document gaps |
