Point it at a directory, git URL, or registry package and it reports the detected toolchain (language, package manager, test command, linter, formatter, CI, etc.) in under 250ms. It outputs JSON following a published schema, making it composable with other tooling. Security-focused subcommands include `brief threat-model` (maps detected stack to CWE/OWASP categories without scanning code) and `brief sinks` (lists ~700 dangerous functions per tool). Detection rules are TOML files requiring no code changes to extend. The author uses it as the first step after cloning any repo and wires it into AI agent instructions so Claude gets repo context in one tool call instead of exploratory greps. ## Full article daily.dev links to this article rather than hosting it.
