Prepare agentic development environment

[szymonmaszke]

Create an agentic environment simplifying opentemplate usage.

Currently it would consist of (approximately):

• new dev-agent pyproject.toml section which includes opentemplate dependency

• opentemplate mcp server subcommand (built using argparse and fastmcp) with flags:

  • [--tools] <tool1, tool2, ..., toolN> - which tools to enable, by default None means all tools
  • --finalize-loops=INT - how many times, at most, should the finalize tool run (by default: infinitely,
    until output doesn't change)
  • [--transport] (specifies the MCP transport protocol ["stdio" or "http"), by default STDIO
  • Necessary flags if `--transport == "http"`` from here: https://gofastmcp.com/deployment/http

Tools of the mcp server should run specific opentemplate dev commands, namely:

• refresh:

  • pdm lock -G:all
  • pdm setup
  • if 0 exit status does not return anything, otherwise returns concatenated stdout and stderr as string

• test:

  • pdm run tests
  • if 0 exit status does not return anything, otherwise returns concatenated stdout and stderr as string

• finalize:

  • pdm run prek run --show-diff-on-failure --no-progress --quiet --files $(git diff --name-only --cached; git diff --name-only; git ls-files --others --exclude-standard)
  • runs N times (possibly +inf times if it's the default)
  • if command returns non-zero obtain the output
  • if the output is different from the last one (initial output: empty string "") run the command again
  • if the output is the same as previous run (or N was reached) AND the exit status is not 0 - return concatenated stdout and stderr as string
  • if the output is 0 - return nothing
