|
8 | | -You are the executor agent for the **numerical-toolbox** project — a numerical algorithms library for DSP, control algorithms, filters, optimizers, and estimators for resource-constrained embedded systems. You implement code changes strictly following project conventions. |
| 8 | +Canonical rules: `AGENTS.md`. Implement exactly what's asked — nothing more. |
9 | 9 |
|
10 | | -Read `CLAUDE.md` at the project root before starting any implementation. It contains all critical constraints and known code inconsistencies. |
| 10 | +## Workflow |
11 | 11 |
|
12 | | -## Implementation Rules |
| 12 | +1. Read the plan/task; search existing patterns and follow them exactly. |
| 13 | +2. Implement one file at a time per all `AGENTS.md` rules. |
| 14 | +3. Write tests first: `TEST_F` on `float`, `StrictMock` only, no heap, Arrange/Act/Assert. |
| 15 | +4. Update `CMakeLists.txt` (new files), `doc/{domain}/{Name}.md` (every algorithm change), |
| 16 | + and `doc/{domain}/README.md` (new algorithms only). |
| 17 | + If a new simulator: add a `cppdbg` entry to `.vscode/launch.json` before `"Linux Debug"`. |
| 18 | +5. Build: `cmake --preset host && cmake --build --preset host` |
| 19 | + Test: `ctest --preset host`. Fix until green. |
| 20 | +6. Report file paths + pass/fail. Nothing else. |
13 | 21 |
|
14 | | -Follow these rules for EVERY change. Violations are unacceptable. |
| 22 | +## Memory — quick reference |
15 | 23 |
|
16 | | -### Memory — ABSOLUTE RULES |
| 24 | +**Forbidden**: `new`/`delete`/`malloc`/`free`, `make_unique`/`make_shared`, |
| 25 | +`std::vector`/`string`/`deque`/`list`/`map`/`set`. |
17 | 26 |
|
18 | | -**FORBIDDEN** — never use: |
19 | | -- `new`, `delete`, `malloc`, `free` |
20 | | -- `std::make_unique`, `std::make_shared` |
21 | | -- `std::vector`, `std::string`, `std::deque`, `std::list`, `std::map`, `std::set` |
| 27 | +**Use instead**: `infra::BoundedVector<T>::WithMaxSize<N>`, `infra::BoundedString::WithStorage<N>`, |
| 28 | +`infra::BoundedDeque<T>::WithMaxSize<N>`, `infra::BoundedList<T>::WithMaxSize<N>`, |
| 29 | +`std::array<T,N>`, `std::optional<T>`. Stack/static only. No recursion. **Tests too.** |
22 | 30 |
|
23 | | -**REQUIRED** — use instead: |
24 | | -- `infra::BoundedVector<T>::WithMaxSize<N>` instead of `std::vector<T>` |
25 | | -- `infra::BoundedString::WithStorage<N>` instead of `std::string` |
26 | | -- `infra::BoundedDeque<T>::WithMaxSize<N>` instead of `std::deque<T>` |
27 | | -- `infra::BoundedList<T>::WithMaxSize<N>` instead of `std::list<T>` |
28 | | -- `std::array<T, N>` for fixed-size arrays |
29 | | -- `std::optional<T>` for optional values |
30 | | -- Stack allocation and static allocation only |
31 | | -- No recursion |
32 | | - |
33 | | -**This applies to test code equally** — no heap allocation in tests either. |
34 | | - |
35 | | -### Numeric Types — TEMPLATE SUPPORT |
36 | | - |
37 | | -Every algorithm MUST support multiple numeric representations: |
38 | | - |
39 | | -```cpp |
40 | | -template<typename T, std::size_t N> |
41 | | -class FirFilter |
42 | | -{ |
43 | | -public: |
44 | | - T Compute(T input); |
45 | | -}; |
46 | | -``` |
47 | | - |
48 | | -- `T = float`, `T = math::Q15`, `T = math::Q31` |
49 | | -- Use `std::numbers::pi_v<float>` — never hardcode `3.14159265f` |
50 | | -- Use fixed-size types (`uint8_t`, `int32_t`) for predictable sizing |
51 | | - |
52 | | -### Compiler Optimizations — EMBEDDED PERFORMANCE |
53 | | - |
54 | | -Every algorithm header file MUST include (immediately after `#pragma once`): |
55 | | - |
56 | | -```cpp |
57 | | -#pragma once |
58 | | - |
59 | | -#if defined(__GNUC__) || defined(__clang__) |
60 | | -#pragma GCC optimize("O3", "fast-math") |
61 | | -#endif |
62 | | -``` |
63 | | - |
64 | | -Apply `OPTIMIZE_FOR_SPEED` on hot-path methods (`Compute()`, `Filter()`, `Calculate()`, `Solve()`, `Update()`, `Step()`): |
| 31 | +## Coverage template (when EMIL_ENABLE_COVERAGE is set) |
65 | 32 |
|
66 | | -```cpp |
67 | | -#include "numerical/math/CompilerOptimizations.hpp" |
68 | | - |
69 | | -template<typename T, std::size_t N> |
70 | | -OPTIMIZE_FOR_SPEED T FirFilter<T, N>::Compute(T input) |
71 | | -{ |
72 | | - // performance-critical implementation |
73 | | -} |
74 | | -``` |
75 | | - |
76 | | -Pure interface/base headers with no algorithm logic are exempt. |
77 | | - |
78 | | -### Naming Conventions |
79 | | - |
80 | | -- **Classes**: `PascalCase` — `FirFilter`, `PidController` |
81 | | -- **Methods**: `PascalCase` — `Compute()`, `Reset()`, `GetOutput()` |
82 | | -- **Member variables**: `camelCase` — `sampleRate`, `coefficients` |
83 | | -- **Namespaces**: lowercase — `filters`, `controllers`, `math`, `analysis` |
84 | | -- **Template parameters**: descriptive — `typename T`, `std::size_t Order` |
85 | | - |
86 | | -### Namespace Conventions |
87 | | - |
88 | | -- Active filters (Kalman family): `namespace filters` — **not** `namespace filters::active` |
89 | | -- Passive filters: `namespace filters::passive` |
90 | | -- Window functions: `namespace windowing` |
91 | | -- See `CLAUDE.md` for the full namespace map. |
92 | | - |
93 | | -### Brace Style — Allman, 4-Space Indent |
94 | | - |
95 | | -```cpp |
96 | | -namespace filters::passive |
97 | | -{ |
98 | | - template<typename T, std::size_t Order> |
99 | | - class FirFilter |
100 | | - { |
101 | | - public: |
102 | | - T Compute(T input); |
103 | | - |
104 | | - private: |
105 | | - std::array<T, Order> coefficients; |
106 | | - }; |
107 | | -} |
108 | | -``` |
109 | | - |
110 | | -### Design Principles |
111 | | - |
112 | | -- **No pure virtual destructors**: Never `virtual ~Interface() = 0`. Use `= default` or omit. |
113 | | -- **No virtual calls in ISR-callable or real-time critical paths** |
114 | | -- **Dependency injection**: All dependencies via constructor, depend on abstractions |
115 | | -- **Small functions**: ~30 lines max (hard limit ~50). Extract named helpers. |
116 | | -- **DRY**: Never duplicate logic. Use templates or helpers for shared code. |
117 | | -- **Brace initialization**: `T value{}` not `T value()`, `Foo obj{arg}` not `Foo obj(arg)`. |
118 | | - |
119 | | -### Error Handling |
120 | | - |
121 | | -- `std::optional<T>` for functions that may not return a value |
122 | | -- Return error codes or status enums — **NO EXCEPTIONS** |
123 | | -- `assert()` or `really_assert()` for precondition checks in debug builds |
124 | | - |
125 | | -### Testing — TYPED TEST PATTERN |
126 | | - |
127 | | -**NEVER use plain `TEST()` macro** — cppcheck reports `syntaxError`. |
128 | | - |
129 | | -Use `TYPED_TEST` for multi-type tests: |
130 | | - |
131 | | -```cpp |
132 | | -#include "numerical/filters/passive/Fir.hpp" |
133 | | -#include <gtest/gtest.h> |
134 | | - |
135 | | -namespace |
136 | | -{ |
137 | | - template<typename T> |
138 | | - class TestFir : public ::testing::Test |
139 | | - { |
140 | | - protected: |
141 | | - filters::passive::Fir<T, 8> filter; |
142 | | - }; |
143 | | - |
144 | | - using TestTypes = ::testing::Types<float, math::Q15, math::Q31>; |
145 | | - TYPED_TEST_SUITE(TestFir, TestTypes); |
146 | | -} |
147 | | - |
148 | | -TYPED_TEST(TestFir, produces_correct_output_for_known_input) |
149 | | -{ |
150 | | - // Arrange, Act, Assert |
151 | | -} |
152 | | -``` |
153 | | -
|
154 | | -Use `TEST_F` for single-type fixture tests. Rules: |
155 | | -- Fixture class and type aliases inside anonymous `namespace {}` |
156 | | -- Test macros (`TEST_F`, `TYPED_TEST`) outside anonymous namespace |
157 | | -- Include `<gtest/gtest.h>` unless gmock matchers are needed |
158 | | -- Use **only** `testing::StrictMock<MockType>` — never `testing::NiceMock<>` or bare `Mock<>` |
159 | | -- No heap allocation in tests — use `std::array`, never `std::vector` or `std::make_unique` |

210 | | -### Documentation — MANDATORY |
211 | | - |
212 | | -For every algorithm added or modified: |
213 | | -- Create or update `doc/{domain}/{AlgorithmName}.md` |
214 | | -- Follow `doc/TEMPLATE.md` exactly |
215 | | -- Mathematical background only — no class names, template params, header paths, or code examples |
216 | | -- Update `doc/{domain}/README.md` if a new algorithm is added |
217 | | - |
218 | | -## Implementation Workflow |
219 | | - |
220 | | -1. Read `CLAUDE.md` and the relevant plan or task |
221 | | -2. Search for existing patterns in the codebase and follow them exactly |
222 | | -3. Implement changes one file at a time |
223 | | -4. Add `#pragma GCC optimize` and `OPTIMIZE_FOR_SPEED` to all algorithm headers |
224 | | -5. Write tests first (TDD): `TYPED_TEST` or `TEST_F`, only `StrictMock`, no heap |
225 | | -6. Update `CMakeLists.txt` for new files |
226 | | -7. Update documentation in `doc/` |
227 | | -8. Add launch configuration to `.vscode/launch.json` if a new simulator was created |
228 | | -9. Build: `cmake --build --preset host` and test: `ctest --preset host` |
| 41 | +## Namespace convention |
| 42 | +Active filters (Kalman family): `namespace filters` — **not** `namespace filters::active`. |

230 | | -## What NOT to Do |
| 44 | +## What NOT to do |
| 45 | +- No extra features, unrelated refactors, docstrings, or one-off abstractions. |
| 46 | +- No Q15/Q31 — float-only; the generic `T` keeps it a cheap future add. |
| 47 | +- No `std::make_unique` anywhere, including tests. |
231 | 48 |
|
232 | | -- Do NOT add features beyond what was requested |
233 | | -- Do NOT refactor code unrelated to the task |
234 | | -- Do NOT add docstrings or comments unless the API is non-obvious |
235 | | -- Do NOT create abstractions for one-time operations |
236 | | -- Do NOT hardcode mathematical constants — use `std::numbers::pi_v<float>` |
237 | | -- Do NOT use `std::make_unique` anywhere, including tests |
| 49 | +**Terse**: no preamble/postamble, no narration; don't re-read files; batch reads; prefer targeted edits. |
