What it does
The `damusix/skills` repository collects skills for packages that are thinly covered in model training data. The agent gets a detailed reference instead of guesses. Topics include T-SQL and SQL Server administration, query performance tuning, PostgreSQL 14 to 18 with pgvector and PostGIS, the Hapi.js framework, HTMX, the Joi validator, scripting with Google zx and Ghost themes. There are also skills on development tooling: structural code search and rewriting with ast-grep, HTTP API tests in Hurl, building CLIs in TypeScript and styling Mermaid diagrams. Separate methodologies describe writing type-safe, access-controlled databases for SQL Server and PostgreSQL. Each skill installs by name.
Who it is for. Developers on SQL Server, PostgreSQL and Node.js whose agents confuse versions and syntax of lesser-known libraries.
Good fit when
- The agent writes T-SQL stored procedures and mixes up version syntax.
- A slow query needs analysis by execution plan and index selection.
- A frontend is built on HTMX without heavy JavaScript.
- An HTTP API is tested with plain-text Hurl scenarios.
Not a fit when
- The project stack does not match the topics: extra skills are pointless.
- General coding rules are needed without tying them to a tool.
- A skill with an explicit license is required for commercial delivery.
Example request
Install the postgres skill and explain which index suits a query filtering on jsonb.Limitations
The set covers 17 topics and each needs its own stack: SQL Server skills are useless in a MySQL project. Some skills describe the author's personal SQL methodology, which you may disagree with. The repository has no license file, so reuse terms are unclear. The last commit was in October 2026. The reference material in a skill affects context spend, so install only what you need.
How to disable. Remove the relevant skill folder from the agent skills directory. Other skills from the set stay in place.
FAQ
How do I install a single skill?
Run `npx skills add damusix/skills --skill mssql-server`, replacing the name with one from the README list.
Which databases are covered?
SQL Server and PostgreSQL 14 to 18, including pgvector, PostGIS, replication and backup.
Are there skills beyond databases?
Yes: Hapi.js, HTMX, Joi, Google zx, Ghost, ast-grep, Hurl, TypeScript CLI building and Mermaid styling.
What license does the set carry?
The repository has no license file, so ask the author about reuse terms.
Which agent is the set for?
Installation goes through `skills.sh`, so agents that read the skill format fit.
