Included with Lifetime

$97 forever

Use when looking up Cognito user details by sub UUID, finding duplicate accounts sharing phone or email, analyzing which duplicates to keep vs delete, or fixing orphaned UNCONFIRMED signups. Symptoms include 403 Forbidden on login, multiple accounts for same phone, backend sync issues.

What this skill does


# Cognito User Analysis

Analyze and fix duplicate Cognito users in clipboard-production by comparing against backend data.

**Skill directory:** This skill's scripts are in `scripts/` relative to this file.

## When to Use

- User reports "403 Forbidden" or can't log in (possible duplicate blocking)
- Need to look up Cognito user details from sub UUIDs
- Finding accounts sharing same phone/email
- Cleaning up orphaned UNCONFIRMED signups
- Backend `cbh_user_id` doesn't match Cognito

**Not for:** Single user attribute updates (use AWS CLI directly)

## Quick Start

```bash
# 1. Verify prerequisites
scripts/check-prerequisites.sh

# 2. Create input file (one sub per line)
echo "68e1e380-d0c1-7028-4256-3361fd833080" > subs.txt

# 3. Pipeline: lookup → find duplicates → analyze → fix
scripts/cognito-lookup.sh subs.txt results.csv
scripts/cognito-find-duplicates.sh results.csv duplicates.csv
scripts/cognito-analyze-duplicates.sh duplicates.csv analysis.csv

# 4. Review analysis.csv, then fix (ALWAYS dry-run first!)
scripts/cognito-fix-duplicates.sh analysis.csv --dry-run
scripts/cognito-fix-duplicates.sh analysis.csv
```

## Prerequisites

Run `scripts/check-prerequisites.sh` to verify. Requirements:

| Requirement                           | Setup                                                       |
| ------------------------------------- | ----------------------------------------------------------- |
| AWS profile `cbh-production-platform` | `aws sso login --profile cbh-production-platform`           |
| `~/.cbh_token`                        | Get from web app dev tools → Network → Authorization header |

See [references/setup.md](references/setup.md) for detailed setup.

## Scripts

All scripts support `--help`. Run `<script> --help` for full usage.

| Script                                  | Purpose                                     |
| --------------------------------------- | ------------------------------------------- |
| `scripts/check-prerequisites.sh`        | Verify AWS + API token are valid            |
| `scripts/cognito-lookup.sh`             | sub → user details CSV                      |
| `scripts/cognito-find-duplicates.sh`    | Find accounts sharing phone/email           |
| `scripts/cognito-analyze-duplicates.sh` | Compare against backend, assign KEEP/DELETE |
| `scripts/cognito-fix-duplicates.sh`     | Execute deletions and updates               |

## Scoring (Analysis)

Compares Cognito accounts against backend to determine which to keep:

| Score | Meaning                                                |
| ----- | ------------------------------------------------------ |
| 185   | Perfect match: cbh_user_id + email + phone + CONFIRMED |
| 100+  | cbh_user_id matches (high confidence)                  |
| 25-99 | Partial match (email or phone only)                    |
| 0-24  | Orphaned signup (UNCONFIRMED, no backend link)         |

Highest score = `KEEP_AND_UPDATE`. Others = `DELETE`.

## Common Mistakes

| Mistake                | Fix                                            |
| ---------------------- | ---------------------------------------------- |
| 403 Forbidden from API | Token expired → get fresh token from web app   |
| Skipping --dry-run     | Always dry-run first. Deletes are permanent.   |
| Wrong AWS profile      | Run `scripts/check-prerequisites.sh` to verify |

cupynumeric-migration-readiness

Included

Pre-migration readiness assessor for porting NumPy to cuPyNumeric. Use BEFORE substantial porting work begins when the user asks whether code will scale on GPU, whether they should migrate to cuPyNumeric, which NumPy patterns transfer cleanly, what must be refactored before porting, or mentions pre-port assessment, scaling analysis, or refactor planning. Inspect the user's source code, look up NumPy usage, cross-reference the cuPyNumeric API support manifest, and distinguish distributed-scaling-friendly patterns from blockers such as unsupported APIs, scalar synchronization, host round-trips, Python/object-heavy control flow, shape/data-dependent branching, and in-place mutation hazards. Produce a verdict of READY, LIGHT REFACTOR, SIGNIFICANT REFACTOR, or NOT RECOMMENDED, with concrete refactor pointers.

Backend & APIsscripts

token-optimizer

Included

Reduce OpenClaw token usage and API costs through smart model routing, heartbeat optimization, budget tracking, and native 2026.2.15 features (session pruning, bootstrap size limits, cache TTL alignment). Use when token costs are high, API rate limits are being hit, or hosting multiple agents at scale. The 4 executable scripts (context_optimizer, model_router, heartbeat_optimizer, token_tracker) are local-only — no network requests, no subprocess calls, no system modifications. Reference files (PROVIDERS.md, config-patches.json) document optional multi-provider strategies that require external API keys and network access if you choose to use them. See SECURITY.md for full breakdown.
