# Geospatial SWE & DevOps Standards
Purpose: code produced as part of geospatial work should run in the user's
real environment and meet peer-level engineering quality. Apply these rules
only when code or repository artifacts are in scope.
## 1. Environment realities (the top error source)
- **Script-first by default**: no `%matplotlib inline`, `!pip install`, or
`display()` unless the user is explicitly in a notebook. Every file runs
from a terminal via `python script.py` behind an
`if __name__ == "__main__":` block. (Cell markers like `# %%` are fine
as an addition — the script must also work without them.)
- **Cross-platform paths**: always `pathlib.Path`; never string-concatenate
or hardcode `/` or `\\`. Ask or detect the user's OS before giving shell
commands; give CMD/PowerShell syntax on Windows, POSIX elsewhere —
don't mix (`export` vs `set`, `venv/bin/activate` vs
`venv\Scripts\activate`).
- **Encodings**: explicit `encoding="utf-8"` on every text file open —
Windows still defaults to legacy code pages, and non-ASCII content
corrupts silently.
- **Modern Python (3.11+)**: `X | None` unions, `type` aliases, structural
pattern matching where they clarify; state the minimum version if a
feature requires it.
## 2. Code quality defaults
Applied to every generated function/module, even when not asked:
```python
def compute_share(values: list[float], total: float) -> list[float]:
"""Return each value's share of the total.
Args:
values: Values to compute shares for.
total: Denominator; must be non-zero.
Returns:
Shares in the same order as values.
Raises:
ValueError: If total is zero.
"""
if total == 0:
raise ValueError("total must be non-zero — share is undefined.")
return [v / total for v in values]
```
- Type hints on every signature; `dataclass`/`TypeAlias` for complex types.
- Google-style docstrings; one-liners suffice for trivial functions.
- **Never bare `except:`**; catch specific exceptions, handle or re-raise
with `raise ... from e`. A silent `pass` costs a week of debugging.
- `logging` over `print` (leveled, formatted), except user-facing CLI
output.
- Note algorithmic complexity where it matters ("this is O(n log n), safe
at n>10⁶") — especially around nested loops and pandas `apply`.
- Magic numbers → named module-level constants.
## 3. Testing and verification
- Offer at least a skeleton pytest for every function carrying real logic:
```python
# test_compute.py — run: python -m pytest -q
import pytest
from compute import compute_share
def test_basic() -> None:
assert compute_share([1, 1], 2) == [0.5, 0.5]
def test_zero_total_raises() -> None:
with pytest.raises(ValueError):
compute_share([1.0], 0)
```
- Numerical code: test edge cases — empty input, NaN, negatives, single
element.
- Run generated code yourself when an execution environment exists;
otherwise mark it explicitly "not executed" — no silent assumptions.
## 4. Dependencies and reproducibility
- New project → virtual environment + pinned `requirements.txt`
(`package==version`); never "install the latest".
- Seed randomness and put the seed in config (details in
`ml-experiment-standards`).
- Note environment-difference risks where relevant (BLAS, CUDA, locale).
## 5. Git practices
- Conventional Commits: `feat(scope): ...`, `fix: ...`, `refactor: ...`;
the body explains *why* — the diff already shows *what*.
- Commit in meaningful units; warn against 500-line single commits.
- Default `.gitignore`: `venv/`, `__pycache__/`, `*.pyc`, large data files
(suggest DVC/LFS), IDE folders.
## 6. Automation / DevOps
- **CI**: minimal GitHub Actions for test + lint (ruff); note OS-runner
differences if jobs must run on Windows too.
- **Docker**: start from `python:3.12-slim`, simple single-stage until
size/caching demands more; note image size and build-cache implications.
- **Monitoring**: any long-lived service/pipeline ships three signals
minimum: structured logs, failure alerting, basic metrics (duration,
volume). ML services add drift checks (see `ml-experiment-standards`).
- **Scheduled jobs**: match the user's platform — cron on POSIX,
Task Scheduler (`schtasks`) on Windows.
## 7. Code review mode
Review in this order and report findings by severity: correctness (edge
cases, silent failures) → security (injection, secrets, path traversal) →
performance (N+1, needless copies, O(n²)) → readability. Every finding
ships with the suggested fix as code — never "this is bad" and nothing
else.
## Execution contract
- **Workflow:** clarify the geospatial code's contract; reproduce the environment; inspect correctness and data invariants; implement the smallest safe change; test; package; document operations and rollback.
- **Decision rules:** apply this skill to geospatial software and pipeline delivery, not generic non-spatial coding; scale CI, containers, and observability to the actual deployment risk.
- **Verification protocol:** run focused and regression tests, lint and type checks where configured, exercise CRS/nodata/geometry edge cases, verify clean installation, and review CI artifacts.
- **Failure modes:** block release for silent data loss, nondeterminism, mutable hidden state, unpinned critical dependencies, secrets, platform assumptions, missing rollback, or unhandled spatial edge cases.
- **Deliverables:** reviewed code, tests, reproducible environment and lock data, CI configuration, operational notes, risk-ranked findings, observability plan, and rollback instructions.
- **Source freshness:** consult [the authoritative source registry](references/authoritative-sources.md) before applying packaging, CI, testing, or supply-chain guidance.

Review before install: Avoid automatic install
License: MIT
Listed tools are metadata hints, not tested compatibility. Agent prompts are suggested handoffs.
Check the source for dependencies, API keys and third-party costs. A public repository does not mean every service is free.
Repository metadata and review signals are advisory. Popularity, source discovery and successful execution are different facts.
Version reported in registry metadata; check source releases before relying on it.

Copies are not installs. Installation counts require a reported successful installation; they are not a blanket quality guarantee.
This page exposes the same decision, trust, audit, use-case, and install signals through the Registry API, so agents can rank this skill without scraping the UI.
