strictspec
Go
Define a schema once in TOML, and generate the full toolchain: validation, versioning, migrations, etc. -- for Go.
strictcli
A CLI framework for the Era of Agents: nothing is inferred, everything is declared. Written in Go.
strictcli is a framework for building command-line programs in Go where nothing is inferred and everything is declared. Every flag and argument states whether it is required, optional, or has a default, every command has help text and declares whether it is read-only or mutating, and a missing declaration is an error when the CLI is registered rather than when someone runs it. It suits developers building CLIs that AI agents will call. strictcli is written in Go, and its source is mirrored at github.com/stricttools/strictcli.
Go framework 0.39.2
What it is
A CLI framework for the Era of Agents: nothing is inferred, everything is declared. Written in Go.
It is for developers who would rather see a mistake when the CLI is declared than when someone runs it.
What it does
- Commands and command groups, with recursive nesting to arbitrary depth
- The presence declaration -- required, optional, or a default -- for every flag and positional argument
- Mandatory effect classification: every command declares
read_onlyormutating - The reserved flag quartet --
--dry-run,--approve-consequential,--quietand--verbose-- delivered on the handler context - MCP server mode -- expose commands as tools over the Model Context Protocol
help --jsonwrites the app's full structure as one canonical JSON document, so the same declaration always produces the same bytes
