Replace 960-line bash script with ~680-line Python module that leans on
pyyaml and jsonschema instead of shelling to yq/jq/awk/sed/envsubst for every
field. Ecosystem dependencies pinned through the existing flake pythonEnv.
Motivation: the generator had outgrown bash. Recent bugs (awk frontmatter
state machine eating markdown ---, envsubst variable scope, shell quoting in
nested heredocs, multi-section rule surgery) were all classic bash pitfalls
that don't exist in Python.
Design notes:
- Uses pyyaml for TEAM.yaml / SETTINGS.yaml parsing.
- Uses jsonschema to validate both inside the generator (previously only in
flake.nix's embedded Python block).
- Does NOT use python-frontmatter because its content-stripping drops
leading blank lines that matter for byte-level parity with bash output.
Replaced with a 6-line fence-split that preserves whitespace exactly.
- Does NOT use tomli-w because it can't emit multiline-basic-string
("\"\"\"...\"\"\"") literals — it would escape every newline in the
developer_instructions body onto a single line, destroying readability.
Codex TOML output is hand-built with a documented comment.
- Opencode skill pool now symlinks per-skill based on applies_to instead
of a blanket symlink, honoring TEAM.yaml's skill filtering.
Verified: snapshotted generated outputs before the port and diffed after.
All of claude/, codex/, opencode/ are byte-identical to baseline except
claude/settings.json, which now uses json.dumps(indent=2) multi-line arrays
instead of hand-built compact arrays — confirmed semantically identical via
json.load comparison.
flake.nix, install.sh, README.md, .gitignore updated to reference
generate.py instead of generate.sh. generate.sh deleted.
