+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Commands
+
+```bash
+# Install dependencies
+make install
+
+# Run tests
+make pytest              # standard test suite
+make pytest-slow         # slow/marked tests with verbose output
+make coverage            # tests with coverage
+
+# Lint and format
+make format              # ruff format + isort
+make lint                # ruff + pylint
+make ruff-lint           # ruff only
+make pylint              # pylint only
+
+# Docs
+make build-docs
+```
+
+**Run a single test file:**
+```bash
+pytest tests/unit/test_environment.py -v
+```
+
+**Run a single test by name:**
+```bash
+pytest tests/unit/test_environment.py::test_methodname_expectedbehaviour -v
+```
+
+## Architecture
+
+RocketPy simulates 6-DOF rocket trajectories. The core workflow is linear:
+
+```
+Environment → Motor → Rocket → Flight
+```
+
+**`rocketpy/environment/`** — Atmospheric models, weather data fetching (NOAA, Wyoming soundings, GFS forecasts). The `Environment` class (~116KB) is the entry point for atmospheric conditions.
+
+**`rocketpy/motors/`** — `Motor` is the base class. `SolidMotor`, `HybridMotor`, and `LiquidMotor` extend it. `Tank`, `TankGeometry`, and `Fluid` support liquid/hybrid propellant modeling.
+
+**`rocketpy/rocket/`** — `Rocket` aggregates a motor and aerodynamic surfaces. `aero_surface/` contains fins, nose cone, and tail implementations. `Parachute` uses trigger functions for deployment.
+
+**`rocketpy/simulation/`** — `Flight` (~162KB) is the simulation engine, integrating equations of motion with scipy's LSODA solver. `MonteCarlo` orchestrates many `Flight` runs for dispersion analysis.
+
+**`rocketpy/stochastic/`** — Wraps any component (Environment, Rocket, Motor, Flight) with uncertainty distributions for Monte Carlo input generation.
+
+**`rocketpy/mathutils/`** — `Function` class wraps callable data (arrays, lambdas, files) with interpolation and mathematical operations. Heavily used throughout for aerodynamic curves, thrust profiles, etc.
+
+**`rocketpy/plots/` and `rocketpy/prints/`** — Visualization and text output, each mirroring the module structure of the core classes.
+
+**`rocketpy/sensors/`** — Simulated sensors (accelerometer, gyroscope, barometer, GNSS) that can be attached to a `Rocket`.
+
+**`rocketpy/sensitivity/`** — Global sensitivity analysis via `SensitivityModel`.
+
+## Coding Standards
+
+- **Docstrings:** NumPy style with `Parameters`, `Returns`, and `Examples` sections. Always include units for physical quantities (e.g., "in meters", "in radians").
+- **No type hints in function signatures** — put types in the docstring `Parameters` section instead.
+- **SI units by default** throughout the codebase (meters, kilograms, seconds, radians).
+- **No magic numbers** — name constants with `UPPER_SNAKE_CASE` and comment their physical meaning.
+- **Performance:** Use vectorized numpy operations. Cache expensive computations with `cached_property`.
+- **Test names:** `test_methodname_expectedbehaviour` pattern. Use `pytest.approx` for float comparisons.
+- **Tests follow AAA** (Arrange, Act, Assert) with fixtures from `tests/fixtures/`.
+- **Backward compatibility:** Use deprecation warnings before removing public API features; document changes in CHANGELOG.

+## Your job (Claude Code)
+
+The scout report and issue above are your source of truth — ignore any diff noise
+from main being ahead of this branch due to the daily sync automation.
+
+1. Read scout.md carefully — Jules has already identified the files and approach.
+
+2. Check if the issue is still open and unassigned upstream before starting:
+   https://github.com/astropy/astropy/issues/${ISSUE_NUMBER:-""}
+
+3. Run the existing tests for the relevant subpackage first to establish a baseline:
+   \`python -m pytest astropy/<subpackage>/tests/ -x -v\`
+
+4. Implement the fix described in scout.md. Follow astropy standards:
+   - Type hints on all new functions
+   - Numpy-style docstrings
+   - Tests in the corresponding tests/ directory
+   - No public API changes unless the issue explicitly requires it
+
+5. Once tests pass, give me a 3-sentence summary of what changed for the PR description.

+# RocketPy fork instructions for Claude Code
+
+## What this repo is
+RocketPy is a 6-DOF rocket trajectory simulator in pure Python. The main source
+code lives in `rocketpy/`. Tests live in `tests/`. The default branch is `master`.
+
+## My workflow
+- I am a solo contributor. Jules scouts issues and creates a branch. I hand off
+  to you (Claude Code) to build the implementation.
+- Branches follow the pattern `scout/YYYY-MM-DD-brief-description`.
+- Read `scout_report.md` in the repo root at the start of every session — it
+  contains the selected issue and any context Jules gathered.
+
+## Scope rules — read these carefully
+- Only touch files directly relevant to the issue. Do not refactor unrelated code.
+- Do not modify existing function signatures unless the issue explicitly requires it.
+- Do not add type hints — the codebase does not use them.
+- Do not rename variables or reformat code outside the files you are changing.
+- If you think something adjacent should be fixed, mention it in a comment to me
+  instead of changing it.
+
+## Code conventions
+- Docstrings: NumPy format only. Every new public function and class needs one.
+  Parameter types go in the docstring (e.g. `x : float`), not as type hints.
+  Do not document units in the type field — just the type name.
+- No magic numbers. Any numeric constant needs a comment explaining what it is.
+- Follow the style of the surrounding code exactly — indentation, spacing, naming.
+
+## Before you consider something done
+- All new public functions have NumPy docstrings
+- Tests written and passing
+- No files modified outside the scope of the issue
+- No type hints added anywhere
+- Diff is clean — no stray whitespace changes, no reformatting of untouched lines
+
+## What to ask me before doing
+- Any change to an existing public API
+- Adding a new dependency
+- Creating a new file that isn't a test or a direct implementation of the issue
+- Anything that feels like it goes beyond the issue scopeß

+## Instructions for Claude Code
 
-## Your job (Claude Code)
+Read CLAUDE.md before doing anything else — it contains scope rules and
+conventions you must follow.
 
-The scout report and issue above are your source of truth — ignore any diff noise
-from main being ahead of this branch due to the daily sync automation.
-
-1. Read scout.md carefully — Jules has already identified the files and approach.
-
-2. Check if the issue is still open and unassigned upstream before starting:
-   https://github.com/astropy/astropy/issues/${ISSUE_NUMBER:-""}
-
-3. Run the existing tests for the relevant subpackage first to establish a baseline:
-   \`python -m pytest astropy/<subpackage>/tests/ -x -v\`
-
-4. Implement the fix described in scout.md. Follow astropy standards:
-   - Type hints on all new functions
-   - Numpy-style docstrings
-   - Tests in the corresponding tests/ directory
-   - No public API changes unless the issue explicitly requires it
-
-5. Once tests pass, give me a 3-sentence summary of what changed for the PR description.
+1. Read the scout report and issue above carefully.
+2. Run existing tests for the relevant module first to establish a baseline:
+   \`python -m pytest tests/ -x -q -k <relevant_test_file>\`
+3. Implement the fix. Stay strictly within the scope of the issue.
+4. Write tests using pytest.approx for any float assertions.
+5. Ensure all new public functions have NumPy docstrings.
+6. When done, give me a 3-sentence summary of what changed for the PR description.

-## Architecture
-
-RocketPy simulates 6-DOF rocket trajectories. The core workflow is linear:
-
-```
-Environment → Motor → Rocket → Flight
-```
-
-**`rocketpy/environment/`** — Atmospheric models, weather data fetching (NOAA, Wyoming soundings, GFS forecasts). The `Environment` class (~116KB) is the entry point for atmospheric conditions.
-
-**`rocketpy/motors/`** — `Motor` is the base class. `SolidMotor`, `HybridMotor`, and `LiquidMotor` extend it. `Tank`, `TankGeometry`, and `Fluid` support liquid/hybrid propellant modeling.
-
-**`rocketpy/rocket/`** — `Rocket` aggregates a motor and aerodynamic surfaces. `aero_surface/` contains fins, nose cone, and tail implementations. `Parachute` uses trigger functions for deployment.
-
-**`rocketpy/simulation/`** — `Flight` (~162KB) is the simulation engine, integrating equations of motion with scipy's LSODA solver. `MonteCarlo` orchestrates many `Flight` runs for dispersion analysis.
-
-**`rocketpy/stochastic/`** — Wraps any component (Environment, Rocket, Motor, Flight) with uncertainty distributions for Monte Carlo input generation.

-**`rocketpy/mathutils/`** — `Function` class wraps callable data (arrays, lambdas, files) with interpolation and mathematical operations. Heavily used throughout for aerodynamic curves, thrust profiles, etc.
-
-**`rocketpy/plots/` and `rocketpy/prints/`** — Visualization and text output, each mirroring the module structure of the core classes.
-
-**`rocketpy/sensors/`** — Simulated sensors (accelerometer, gyroscope, barometer, GNSS) that can be attached to a `Rocket`.

-## Coding Standards
-
-- **Docstrings:** NumPy style with `Parameters`, `Returns`, and `Examples` sections. Always include units for physical quantities (e.g., "in meters", "in radians").
-- **No type hints in function signatures** — put types in the docstring `Parameters` section instead.
-- **SI units by default** throughout the codebase (meters, kilograms, seconds, radians).
-- **No magic numbers** — name constants with `UPPER_SNAKE_CASE` and comment their physical meaning.
-- **Performance:** Use vectorized numpy operations. Cache expensive computations with `cached_property`.
-- **Test names:** `test_methodname_expectedbehaviour` pattern. Use `pytest.approx` for float comparisons.
-- **Tests follow AAA** (Arrange, Act, Assert) with fixtures from `tests/fixtures/`.
-- **Backward compatibility:** Use deprecation warnings before removing public API features; document changes in CHANGELOG.

-# RocketPy fork instructions for Claude Code
-
-## What this repo is
-RocketPy is a 6-DOF rocket trajectory simulator in pure Python. The main source
-code lives in `rocketpy/`. Tests live in `tests/`. The default branch is `master`.
-
-## My workflow
-- I am a solo contributor. Jules scouts issues and creates a branch. I hand off
-  to you (Claude Code) to build the implementation.
-- Branches follow the pattern `scout/YYYY-MM-DD-brief-description`.
-- Read `scout_report.md` in the repo root at the start of every session — it
-  contains the selected issue and any context Jules gathered.
-
-## Scope rules — read these carefully
-- Only touch files directly relevant to the issue. Do not refactor unrelated code.
-- Do not modify existing function signatures unless the issue explicitly requires it.
-- Do not add type hints — the codebase does not use them.
-- Do not rename variables or reformat code outside the files you are changing.
-- If you think something adjacent should be fixed, mention it in a comment to me
-  instead of changing it.
-
-## Code conventions
-- Docstrings: NumPy format only. Every new public function and class needs one.
-  Parameter types go in the docstring (e.g. `x : float`), not as type hints.
-  Do not document units in the type field — just the type name.
-- No magic numbers. Any numeric constant needs a comment explaining what it is.
-- Follow the style of the surrounding code exactly — indentation, spacing, naming.
-
-## Before you consider something done
-- All new public functions have NumPy docstrings
-- Tests written and passing
-- No files modified outside the scope of the issue
-- No type hints added anywhere
-- Diff is clean — no stray whitespace changes, no reformatting of untouched lines
-
-## What to ask me before doing
-- Any change to an existing public API
-- Adding a new dependency
-- Creating a new file that isn't a test or a direct implementation of the issue
-- Anything that feels like it goes beyond the issue scopeß

-
-Read CLAUDE.md before doing anything else — it contains scope rules and
-conventions you must follow.
-
-1. Read the scout report and issue above carefully.
-2. Run existing tests for the relevant module first to establish a baseline:
-   \`python -m pytest tests/ -x -q -k <relevant_test_file>\`
-3. Implement the fix. Stay strictly within the scope of the issue.
-4. Write tests using pytest.approx for any float assertions.
-5. Ensure all new public functions have NumPy docstrings.
-6. When done, give me a 3-sentence summary of what changed for the PR description.
