dsh-devkit

An agent in the middle of a task reaches for small deterministic operations constantly — JSON-to-YAML round-trip, SQL dialect transpiling, text diffing, regex testing, timezone and unit conversion. Prompting a model to do any of these is slow, expensive, and not reproducible. Transpiling a MySQL statement to Snowflake is not something you can wing from context.

dsh-devkit packages these operations into 14 remote tools that return a deterministic result in a single call. transpile_sql runs a real parser across MySQL, PostgreSQL, BigQuery, Snowflake, ClickHouse, Doris, StarRocks and more, so a syntax error comes back with line and column instead of a confident-looking rewrite. The remaining tools cover JSON Schema validation, LCS-based text diff, JWT decoding, regex matching with named capture groups, QR code generation, unit and timezone conversion, PII redaction, and full-page screenshots. A natural-language helper, what_can_you_do, lets you describe a task in any language and get back the exact tool plus a ready-to-run call.

The plugin is a single cordis.patch.yml configuration row — no tool code, build step, or lifecycle script runs locally. Documents and prompts are processed in memory and not retained. The free tier requires no signup. It is aimed at developers building agent workflows on the dsh v0.1 developer preview who want to pull deterministic utility calls out of the prompt loop.
