dsh-fmt

In a DSH workflow, raw text often arrives with inconsistent indentation, mixed-case SQL keywords, and unpredictable field ordering, and manually validating and reformatting it every time is slow and error-prone. dsh-fmt collapses that into a single format_text call: feed in the original text and a target format, and you get back either a validated, canonically formatted result or a clear error with line and column information.

The plugin covers JSON, YAML, TOML, and SQL. JSON and YAML are parsed first and then stringified with pretty-printing, expanding flow-style arrays into block style; TOML follows the same parse-then-normalize path with position details lifted directly from the parser error. SQL supports four dialects (standard, PostgreSQL, MySQL, SQLite) and lets you choose keyword casing as upper, lower, or preserve. A deliberate design rule keeps the pipeline robust: a parse failure never throws a tool-level exception. The caller always receives a structured ok flag plus an error message, so one bad snippet cannot crash the entire pipeline.

Written as pure ESM with no build step and no native dependencies, the plugin is ready to use the moment it is installed. It fits developers building prompt-assembly pipelines, cleaning external data, validating user-submitted config fragments, or embedding a lightweight formatting step into an agent tool chain in DSH.
