testland/liquibase-migrations

Authors and runs Liquibase database migrations - changelog-driven schema management with changesets in XML / YAML / JSON / SQL formats; supports `liquibase update` / `status` / `rollback` / `tag` / `history` lifecycle; offers per-changeset preconditions, contexts and labels for selective execution, and rollback semantics; tracks state in `DATABASECHANGELOG` + `DATABASECHANGELOGLOCK` tables. Use when the user works with Liquibase-managed schemas (Spring Boot heritage, polyglot DB shops), needs cross-DBMS portable migrations, or requires fine-grained rollback control.

Quality

Content

80%

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

Actionable and concise with concrete executable examples and a well-sequenced step structure. The main gaps are the lack of an explicit validate-then-fix feedback loop in the migration workflow, and a monolithic layout with no progressive disclosure to separate reference files.

Suggestions

Add an explicit validation checkpoint to the workflow - e.g. 'run `liquibase validate` and `liquibase status` before `liquibase update`; on checksum/syntax errors, fix the changelog and re-validate before proceeding' - to create a validate-fix-retry feedback loop for destructive migrations.

Split the long-form reference material (full changeset format syntax, the preconditions predicate catalog, and the anti-patterns table) into bundled reference files under references/ and link to them one level deep, so SKILL.md stays a lean overview.

Trim the Overview marketing quote ('helps millions of developers...') to a one-line factual summary to keep the opening token-lean.

DimensionReasoningScore

Conciseness

Lean and assumes competence - relies on tight code blocks, a commands table, and a YAML changeset example rather than explaining basic concepts; the only mild fluff is the marketing quote in the Overview, which is minimal.

3 / 3

Actionability

Fully executable, copy-paste-ready guidance: `docker run` invocation with real flags, concrete YAML changesets with rollback blocks, the preconditions YAML, and an exact commands table covering update/status/rollback/tag/validate.

3 / 3

Workflow Clarity

Steps 1-8 are clearly sequenced and `liquibase validate` plus adversarial review are mentioned, but the workflow lacks an explicit validation checkpoint/feedback loop (validate -> fix -> retry) woven into the flow; for destructive database migrations this caps the score at 2.

2 / 3

Progressive Disclosure

Well-organized with clear section headers, but the skill is monolithic - all content (full YAML examples, precondition catalog, anti-patterns) is inline with no bundled reference files to defer to, so content that could be split out is kept in the body.

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, specific description that covers concrete actions, natural trigger terms, both what-and-when, and a distinct niche versus sibling migration tools. No vague fluff or over-claims.

DimensionReasoningScore

Specificity

Names many concrete actions and capabilities - 'Authors and runs Liquibase database migrations', changeset formats (XML/YAML/JSON/SQL), the `update`/`status`/`rollback`/`tag`/`history` command lifecycle, preconditions, contexts/labels, and the `DATABASECHANGELOG`/`DATABASECHANGELOGLOCK` state tables.

3 / 3

Completeness

Explicitly answers both what (the full capability list) and when via the 'Use when the user works with Liquibase-managed schemas... needs cross-DBMS portable migrations, or requires fine-grained rollback control' trigger clause.

3 / 3

Trigger Term Quality

Uses natural terms a user would say - 'Liquibase database migrations', 'Liquibase-managed schemas', 'Spring Boot', 'cross-DBMS portable migrations', 'rollback control' - plus the literal `liquibase update`/`status`/`rollback` command names; third-person voice ('Authors and runs') is correct.

3 / 3

Distinctiveness Conflict Risk

Clear niche (Liquibase vs Flyway via format-portable, rollback-aware changesets) with distinct triggers; unlikely to fire for the wrong skill, and it names the sister tools it differs from.
