# Security Hardening Orchestrator
## CRITICAL BEHAVIORAL RULES
You MUST follow these rules exactly. Violating any of them is a failure.
1. **Execute steps in order.** Do NOT skip ahead, reorder, or merge steps.
2. **Write output files.** Each step MUST produce its output file in `.security-hardening/` before the next step begins. Read from prior step files — do NOT rely on context window memory.
3. **Stop at checkpoints.** When you reach a `PHASE CHECKPOINT`, you MUST stop and wait for explicit user approval before continuing. Use the AskUserQuestion tool with clear options.
4. **Halt on failure.** If any step fails (agent error, test failure, missing dependency), STOP immediately. Present the error and ask the user how to proceed. Do NOT silently continue.
5. **Use only local agents.** All `subagent_type` references use agents bundled with this plugin or `general-purpose`. No cross-plugin dependencies.
6. **Never enter plan mode autonomously.** Do NOT use EnterPlanMode. This command IS the plan — execute it.
## Pre-flight Checks
Before starting, perform these checks:
### 1. Check for existing session
Check if `.security-hardening/state.json` exists:
- If it exists and `status` is `"in_progress"`: Read it, display the current step, and ask the user:
```
Found an in-progress security hardening session:
Target: [target from state]
Current step: [step from state]
1. Resume from where we left off
2. Start fresh (archives existing session)
```
- If it exists and `status` is `"complete"`: Ask whether to archive and start fresh.
### 2. Initialize state
Create `.security-hardening/` directory and `state.json`:
```json
{
"target": "$ARGUMENTS",
"status": "in_progress",
"depth": "comprehensive",
"compliance_frameworks": ["owasp"],
"current_step": 1,
"current_phase": 1,
"completed_steps": [],
"files_created": [],
"started_at": "ISO_TIMESTAMP",
"last_updated": "ISO_TIMESTAMP"
}
```
Parse `$ARGUMENTS` for `--depth` and `--compliance` flags. Use defaults if not specified.
### 3. Parse target description
Extract the target description from `$ARGUMENTS` (everything before the flags). This is referenced as `$TARGET` in prompts below.
