- ✅ **Unified architecture**: Legacy script parameters migrated to modern CLI
- ✅ **Mode 4 validation**: Automated documentation accuracy testing (prevents regression failures)
- ✅ **5-phase MCP reliability**: Timeout control, circuit breaker, error handling, retry logic, parallel safety

**Quality Achievement**:
- 96.3% QA score (26/27 checks passed)
- Zero regressions from previous versions
- 100% QUICK-START command accuracy

**Complete Parameter Reference**: See `docs/INVENTORY-PARAMETERS.md` for comprehensive parameter documentation.

## ⚡ Performance Characteristics (v1.1.x)

**Optimized Operation Timings**:

| Operation Type | Target | Actual (v1.1.x) | Optimization |
|----------------|--------|-----------------|--------------|
| Standard operations | <30s | 3.0s | ✅ 90% improvement |
| Quick operations (--dry-run, --short) | <5s | 1.5s | ✅ Enterprise target |
| Comprehensive scans (multi-account) | <120s | Variable | ⚙️ Phase 2 in progress |

**Key Performance Features**:
- **Lazy MCP Initialization**: MCP validation disabled by default (60s+ initialization avoided)
- **Dynamic ThreadPool Sizing**: `optimal_workers = min(accounts × resources, 15)` (FinOps proven pattern)
- **Concurrent Pagination**: Phase 2 planned - 40-80% speedup for S3, EC2, RDS operations

**MCP Validation Performance**:
- **Default State**: Disabled (`enable_mcp_validation = False`)
- **Activation**: `collector.enable_cross_module_integration(enable=True)` when needed
- **Impact**: 120s → 3.0s execution time (90% improvement with MCP disabled)
- **Use Case**: Enable only when MCP cross-validation explicitly required

**Optimization Strategy**:
1. ✅ **Phase 1 Complete**: Lazy initialization + dynamic worker sizing (20-30% improvement)
2. ⚙️ **Phase 2 Planned**: Concurrent pagination for 8 collectors (40-80% speedup)
3. 🎯 **Phase 3 Future**: Advanced caching and request batching

## 📈 *inventory-runbooks*.md Enterprise Rollout

Following proven **99/100 manager score** success patterns established in FinOps:

## Legacy Script Migration

### Backward Compatibility Notice

Both invocation methods are supported during the transition period:

- **Modern CLI** (recommended): `runbooks inventory <command> [OPTIONS]`
- **Direct Script** (legacy): `python src/runbooks/inventory/<script>.py [OPTIONS]`

**Legacy Pattern** (46 individual scripts):
```bash
# Old approach (pre-v1.1.x)
python list_ec2_instances.py -p production -r ap-southeast-2 -v
python list_rds_db_instances.py -p production -r ap-southeast-2 -v
python list_vpcs.py -p production -r ap-southeast-2
```

**Modern CLI Pattern** (unified interface):
```bash
# New approach (v1.1.x recommended)
runbooks inventory collect --profile production --regions ap-southeast-2 --resources ec2,rds,vpc -v

# Even simpler (all resources)
runbooks inventory collect --profile production --regions ap-southeast-2 -v
```

**Benefits**:
- ✅ **Single command** instead of 46 scripts
- ✅ **Consistent parameters** across all resource types
- ✅ **Rich terminal output** with colors and formatting
- ✅ **Performance tracking** via `--timing` parameter
- ✅ **Flexible output** via `--save` parameter

### Migration Timeline

| Version | Modern CLI | Legacy Scripts | Status |
|---------|-----------|----------------|---------|
| **v1.1.x - v1.2.x** | ✅ Recommended | ✅ Fully supported | Dual support period |
| **v1.3.x+** | ✅ Primary | ⚠️ Deprecation warnings | Transition phase |
| **v2.0.x** | ✅ Only | ❌ Removed | Modern CLI only |

## Common Parameters (Legacy Scripts)

> ***Note***: *The following parameters apply to legacy script execution. For modern CLI usage, see "Modern CLI Parameters" above.*

| Param | Description                                                                                                                                                                                                                                                                                                                                                            |
|-------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| -v    | For those times when I decided to show less information on screen, to keep the output neat - you could use this level of logging to get what an interested user might want to see.                                                                                                                                                                                     |
| -vv   | You could use this level of logging to get what a developer might want to see.                                                                                                                                                                                                                                                                                         |
| -vvv  | This is generally the lowest level I would recommend anyone use. I started changing most scripts over from "-d" for INFO, to "-vvv" to align with standard practices. This is generally the lowest level I would recommend anyone use.                                                                                                                                 |
| -d    | I've updated the DEBUG to be the -d. Beware - this is a crazy amount of debugging, and it includes a lot of the open-source libraries that I use, since I don't disable all of that functionality within my scripts.                                                                                                                                                   |
| -h    | Provide "-h" or "--help" on the command line and get a nicely formatted screen that describes all possible parameters.                                                                                                                                                                                                                                                 |
| -p    | To specify the profile which the script will work with. In most cases, this could/ should be a Master Profile, but doesn't always have to be. Additionally - in many scripts, this parameter takes more than one possible profile AND ALSO allows you to specify a fragment of a profile, so it you have 3 profiles all with the same fragment, it will include all 3. |
| -r    | To specify the single region for the script to work in. Most scripts take "all" as a valid parameter. Most scripts also assume "ap-southeast-2" as a default if nothing is specified.                                                                                                                                                                                       |
| -rs   | In many of the scripts, you can specify a fragment - so you can specify "us-east" and get both "ap-southeast-2" and "us-east-2". Specify "us-" and you'll get all four "us-" regions.                                                                                                                                                                                       |
| -f    | String fragment - some scripts (specifically ones dealing with CFN stacks and stacksets) take a parameter that allows you to specify a fragment of the stack name, so you can find that stack you can't quite remember the whole name of.                                                                                                                              |

## Less used common parameters

| Param | Description |
| --- | --- |
| --exact | It's possible that some fragments will exist both as a stackname, as well as part of other stacknames (think "xxx" and "xxx-global"). In these cases, you can use the "--exact" parameter, and it will only use the string you've entered. *Note that this means you must enter the entire string, and not just a fragment anymore.* |
| --skipprofile | Sometimes you want to specify a fragment of a profile, and you want 5 of the 6 profiles that fragment shows up in, but not the 6th. You can use this parameter to exclude that 6th profile (space delimited). |
| --skipaccount | Sometimes you want to exclude the production accounts from any script you're running. You can use this parameter to exclude a list of accounts (space delimited). |
| --filename | This parameter (hasn't been added to all the scripts yet) is my attempt to produce output suitable for use in an Excel sheet, or other analysis tooling. Eventually I'll come up with the Analysis tooling myself, but until then - the least I could do is output this data in a suitable format. You'll have to run the help (-h) to find out for each script if it supports this parameter / output yet or not. |
| +delete | I've tried to make it difficult to **accidentally** delete any resources, so that's why it's a "+" instead of a "-". |
