Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00099 | $0.03121 |
| Opus 5 | $0.00049 | $0.01561 |
| Sonnet 5 | $0.00020 | $0.00624 |
| Haiku 4.5 | $0.00010 | $0.00312 |
Grade A, and why
database-migration-service-expertise scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

AWS DMS Operational Review & Troubleshooting
Conduct comprehensive operational reviews, best practices validation, troubleshooting, and cost optimization assessments for AWS Database Migration Service (DMS) environments aligned with AWS Well-Architected principles.
When to Use
Activate this skill when the user asks to:
- Review, audit, or assess DMS configurations
- Check DMS best practices compliance
- Troubleshoot DMS task failures, latency, or connectivity issues
- Evaluate DMS cost optimization opportunities
- Plan or execute a database migration cutover
- Assess DMS version deprecations and upgrade paths
- Run a pre-migration assessment
- Evaluate DMS Serverless vs provisioned suitability
- Investigate data validation mismatches
- Review DMS homogeneous data migration options
Step 1: Identify Target Resources
Ask the user which DMS resources to review. Accept:
- Specific replication instance names and regions
- Specific replication task identifiers
- "all instances" in a specific region
- "all instances in all regions"
Query AWS APIs to discover DMS resources:
- List replication instances across the configured account regions
- List replication tasks and their states
- List endpoints and connectivity status
Step 2: Collect DMS Configuration
For EACH replication instance and its associated tasks, gather the following data using AWS APIs.
2.1 Replication Instance Config
Engine version, instance class, Multi-AZ, storage, public accessibility, KMS encryption, auto-upgrade, VPC/subnet configuration, pending maintenance actions.
aws dms describe-replication-instances --profile <profile> --region <region>
aws dms describe-pending-maintenance-actions --profile <profile> --region <region>
2.2 Replication Tasks
Task identifiers, status, migration type, table mappings, task settings, CDC start positions, last failure messages, stop reasons, replication task statistics.
aws dms describe-replication-tasks --profile <profile> --region <region>

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

database-migration-service-expertise is a skill published in the GitHub repository aws/tools-for-devops-agent (45 stars, last pushed yesterday), licensed Apache-2.0. It adds 99 tokens to every session and 3,121 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
