jsonpath-and-jsonb
Skill1 starsChanged 6 months agoPostgreSQLView on GitHub
PostgreSQL's SQL/JSON support — jsonpath (SQL:2016 path language) + jsonb (binary-encoded JSON) + the SQL/JSON operators like `->`, `->>`, `@?`, `@@`, `jsonb_path_query`. Covers `src/backend/utils/adt/jsonb*.c` (jsonb storage + operators + GIN opclass + subscripting) and `jsonpath*.c` (path language parser + executor). Loads when the user asks about jsonpath semantics, path variables ($, @, current), lax vs strict mode, predicate expressions, `jsonb_path_query` / `jsonb_path_exists`, JSON_TABLE (SQL:2023 / PG 17+), jsonb_gin operator class, memory management in jsonpath_exec (Tom Lane's 5a2043bf713 rewrite), or "why is my JSON search slow" (usually GIN or path complexity). Skip when the ask is about the older `json` type (`json.c` is separate — text representation) or about JSON output formats (that's `format_type` territory).

The file
We split this skill into the rules it gives an agent
6 rules. About 0 are common, 3 are distinctive, and 3 are very specific to this project.
≈0
Common · estimate
Many files like this have a rule of this kind.
≈3
Distinctive · estimate
This author's own choices. Worth a look.
3
Very specific
Tied to their project's names, files or tools. Probably skip.
Licensed with conditions — read it at the source. We count its rules but don't quote them. Read them on GitHub.
≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.
Does it work?
Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.
Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
