-# Reviewing ESPHome pull requests
-
-ESPHome parses YAML into C++ firmware for memory-constrained microcontrollers
-(ESP32, ESP8266, RP2040, LibreTiny). Review changes with that in mind: RAM and
-flash are scarce, and code runs unattended for months.
-
-`AGENTS.md` in the repository root is the full contributor guide and the
-authority when it disagrees with this summary. The developer documentation at
-https://developers.esphome.io explains the component lifecycle and the reasoning
-behind these rules. This skill lists the concrete things worth flagging in a
-review; read `AGENTS.md` for the detail behind any item.
-
-Only raise findings that the diff actually introduces or changes. Do not ask for
-drive-by cleanup of pre-existing code the PR did not touch.
-
-## Memory and embedded constraints (highest value)
-
-Heap allocation after `setup()` is treated as a reliability bug, not a
-performance nit, because it fragments a small shared heap. Flag:
-
-- New heap allocation on a hot path or after setup that could be avoided.
-- `std::vector` where the size is known at compile time (use `std::array`, or
-  `StaticVector<T, N>` when a `push_back` API is needed) or fixed at runtime
-  init (use `FixedVector<T>`).
-- Listener / child-entity registration lists stored as `std::vector`; these have
-  a compile-time-known count and should use `cg.slot_counter()` plus
-  `StaticVector`.
-- `std::vector<uint8_t>` for a byte buffer that never grows: prefer
-  `std::unique_ptr<uint8_t[]>` or `std::array`.
-- `std::map` / `std::set` / `std::unordered_map` for small datasets (1-16
-  elements): a `std::vector` of a small struct with linear search is lighter.
-- `std::deque` anywhere: it allocates 512-byte blocks and should be avoided.
-- `std::string` storing a value set once from config: prefer `StringRef` (the
-  literal already lives in flash).
-- `std::string` / `std::to_string` / string-returning helpers on hot paths where
-  a buffer or view API exists.
-
-## C++ conventions
-
-- Include what you use: a file referencing a symbol must include the header that
-  declares it, even if it currently arrives transitively. New or changed uses of
-  a symbol need the matching include.
-- Prefix all member access with `this->`.
-- Naming: `lower_snake_case` for functions/methods/variables, `UpperCamelCase`
-  for classes/structs/enums, `UPPER_SNAKE_CASE` for namespace-scope constants,
-  trailing underscore on protected/private fields.
-- `enum class` values must be prefixed with the enum name in `UPPER_SNAKE_CASE`
-  (e.g. `UARTFlushResult::UART_FLUSH_RESULT_SUCCESS`). Bare names like `SUCCESS`,
-  `FAIL`, or `OK` collide with SDK macros on some platforms and break the build.
-- Prefer `const`/`enum` over `#define`; `#define` is only for conditional
-  compilation and code-generation sizes.
-- Never call `millis()` in a `loop()` body; use
-  `App.get_loop_component_start_time()`. A rate-limit gate below ~16 ms (the loop
-  period) does nothing.
-- Pick the timing primitive by cadence: gated `loop()` under 250 ms,
-  `set_interval` at 500 ms and above.
-- Do not override a base method to return the value it already returns (e.g.
-  `get_setup_priority()` returning `setup_priority::DATA`).
-- Wrap string literals passed as printf `%s` args in `LOG_STR_LITERAL()`.
-- Required, invariant dependencies should be constructor parameters, not setters.
-- Callback registration methods must be templated (`template<typename F>`), not
-  typed as `std::function`, so lightweight forwarders avoid a heap allocation.
-- Two-space indent, `using` over `typedef`, wrap at 120 columns.
-
-## Python conventions
-
-- Type-annotate every new function signature (params and return), new dataclass
-  fields, and new module-level variables. Import `ConfigType` from
-  `esphome.types`.
-- Use the walrus operator to avoid a double lookup, e.g.
-  `if (blah := config.get(CONF_BLAH)) is not None:`.
-- Reuse existing validators from `config_validation.py` (`cv.rename_key`,
-  `cv.has_exactly_one_key`, etc.) via `cv.All(...)` instead of hand-rolling.
-- `esphome/const.py` is frozen: no new `CONF_` constants there. Define them in
-  the component's own `.py`, or in `esphome/components/const/__init__.py` when
-  shared. The same constant defined in three or more component files fails CI.
-- State that must persist during code generation goes in `CORE.data` namespaced
-  under the component `DOMAIN` (a `@dataclass`), not module-level mutable globals.
-- Prefer callback-based triggers via `build_callback_automation()`; only use a
-  `Trigger<Ts...>` subclass when the forwarder needs mutable state.
-
-## Testing and coverage
-
-- New and changed lines and branches need test coverage, including defensive
-  early-returns, error paths, and no-op guards. A mocked-out function is not
-  covered; exercise the real call path too.
-- Component YAML tests live in `tests/components/<component>/`. Never define
-  buses (uart, i2c, spi, modbus) directly in a test file: pull them from
-  `tests/test_build_components/common/` through dict-style `packages:` so CI can
-  group builds. List-style packages or top-level merge keys block grouping.
-- Config-only checks use the `validate.*.yaml` prefix; compiled checks use
-  `test.*.yaml`.
-
-## Breaking changes and public API
-
-- Base classes under `esphome/core/` and documented config options are public
-  API. Undocumented `public` members of a component are internal.
-- A breaking change needs justification, a migration path in the PR description,
-  and a deprecation window where feasible (`ESPDEPRECATED` in C++,
-  `cv.rename_key(..., removed_in=...)` in Python). Changing a codegen-injected
-  lambda signature is not a breaking change.
-
-## Process and PR hygiene
-
-- PR titles start with a `[tag]` prefix: the component name (e.g. `[uart] ...`)
-  or `[core]` for shared code.
-- Prose in docs, comments, and commit messages should be plain English. Keep
-  inline comments short and only where the code is not self-explanatory; do not
-  restate what the code says.
-- Verify the PR fills out `.github/PULL_REQUEST_TEMPLATE.md` and adds
-  `CODEOWNERS` entries for a new component.

-        ## Use of AI in bug reports
-
-        AI tools are good at carrying out well-defined tasks, but they are not good at troubleshooting.
-        Please do NOT paste an AI-generated wall of text into the issue template - if the AI hasn't solved
-        your problem, its wild guesses are not likely to help.
-
-        Please DO include your own words and observations, compile/boot logs, and
-        especially a minimal reproducible example of your YAML configuration that demonstrates the problem.
-
-        It is however quite acceptable to use AI to translate your *own* report,
-        if you aren't a competent English speaker.
-
-        If you really think it will be useful to include an AI's analysis, preferably wrap it in a `<details>` block which will be collapsed by default.
-
-        If you are using AI to help solve a problem, rather than asking it to speculate about what the problem is,
-        it can be more useful to ask it to create a step-by-step troubleshooting procedure.
-        AI is also useful for generating boilerplate code, such as a minimal reproducible example of your YAML
-        configuration that demonstrates the problem.
-
-        Used properly, AI can be a useful tool to help you solve your problem, but don't let it get in the way.

-        rebuilds the callback and re-queues a scheduler item, and the period drifts.
-    *   **Scheduler ids:** name a timer only when it must be cancelled or replaced, and use a
-        `static constexpr uint32_t` id, never a string. Ids are per component instance and cannot clash with other
-        components, so number them from 0 and keep all of a component's ids together in one place.

-        `this->mark_failed(LOG_STR(ESP_LOG_MSG_COMM_FAIL))`, and give an action whose payload is a byte array
