rds-db2

Provisions, connects, migrates, and operates Amazon RDS for Db2. Applies when provisioning with IBM customer and site IDs (License Manager, BYOL, GovCloud), connecting over TLS, fixing SQL30082N after Secrets Manager rotation, migration from Db2 LUW (Linux, AIX, Windows, AS400) or z/OS mainframe (ADB2GEN, Q Replication), choosing code page/collation (EBCDIC, CCSID), S3 backup/restore, Multi-AZ and cross-region standby replicas, RDSADMIN procedures, customer-managed KMS BYOK, self-managed Active Directory Kerberos, Db2 audit to S3, minimum IAM, or colocation.

Quality

Content

85%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A high-quality operational skill: actionable commands and exact signatures, a clear validated workflow, and excellent progressive disclosure via a verified reference bundle. The main drag is conciseness — repeated MUST constraints and fact blocks across sections inflate the body without adding new information.

Suggestions

Consolidate the recurring "The agent MUST ..." constraint lists (they appear nearly verbatim in Verify Dependencies, Classify and Route, Execute Workflow, and Security) into a single shared constraints section to remove repetition.

Tighten the "RDS-managed facts the agent must always surface" section: several six-item fact lists overlap with the Troubleshooting and Security sections; cross-reference instead of restating to cut tokens.

Move the per-scenario MUST-tell checklists that are already detailed in their sub-skill references (e.g. byok-kms, ad-kerberos) to brief pointers rather than full restatements in SKILL.md.

Dimension	Reasoning	Score
Conciseness	Most content is operationally specific (RDSADMIN signatures, exact CLI flags, error codes) that Claude does not already know, but the same "The agent MUST ..." constraint lists and six-item "RDS-managed facts" blocks recur across Common Tasks, the facts section, Troubleshooting, and Security, so it could be tightened rather than scoring as lean and fully token-efficient.	2 / 3
Actionability	It provides fully executable AWS CLI commands (e.g. `aws rds create-db-instance-read-replica --replica-mode mounted`), exact procedure signatures (`rdsadmin.restore_database(dbname, type, prefix, bucket, region)`), and copy-paste `--tags` syntax, matching the anchor for fully executable, copy-paste-ready guidance.	3 / 3
Workflow Clarity	The Verify Dependencies -> Classify and Route -> Execute sequence is clearly laid out with a routing table, explicit validation checkpoints (dependency checks, standby-replica prerequisites, schema validation of the handoff artifact), and feedback loops for destructive database operations, satisfying the anchor for clear sequencing with validation rather than the checkpoint-missing level below.	3 / 3
Progressive Disclosure	SKILL.md is an overview with a routing table pointing to 15 one-level-deep reference files (all verified present in references/), plus bundled scripts and assets; navigation is well-signaled and content is appropriately split rather than monolithic.	3 / 3

Description

100%

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong, third-person description that explicitly covers what the skill does and when to use it, with rich natural trigger terms and a distinctive Db2-on-RDS niche. Its only weakness is verbosity — the single long sentence could be tightened without losing any trigger coverage.

Dimension	Reasoning	Score
Specificity	"Provisions, connects, migrates, and operates Amazon RDS for Db2" lists multiple concrete actions and then enumerates specific scenarios (S3 backup/restore, Multi-AZ standby, RDSADMIN procedures), matching the anchor for listing multiple specific concrete actions rather than the partial level below.	3 / 3
Completeness	It states what the skill does (provisions/connects/migrates/operates RDS for Db2) and gives an explicit "Applies when" trigger clause, so both what and when are clearly answered rather than the when being merely implied (which would cap at 2).	3 / 3
Trigger Term Quality	The "Applies when ..." clause surfaces natural operator vocabulary — SQL30082N, Secrets Manager rotation, z/OS mainframe, ADB2GEN, Q Replication, CCSID, Multi-AZ, BYOK, Kerberos, colocation — giving strong coverage of terms users would actually say, not just technical jargon.	3 / 3
Distinctiveness Conflict Risk	The RDS-for-Db2 niche with Db2-specific triggers (RDSADMIN, SQL30082N, ADB2GEN, CCSID, EBCDIC) is clearly distinguishable and unlikely to fire for a different database skill.	3 / 3
