What it does
Hal And Abstractions is an agent skill from yokki-vans/InkPointX. Layering and abstraction discipline for the firmware. Use when touching storage, input, display, settings, i18n, or rendering, or any code that could reach into the SDK. Covers routing through the HAL (HalStorage / HalGPIO / HalDisplay) instead of raw SDK classes, MappedInputManager logical buttons instead of raw GPIO indices, UITheme/GUI for all rendering, the singleton macros, tr() for user-facing text, and where a new abstraction boundary belongs.
Its SKILL.md is about 790 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Frontend & Design, covering Internationalization. The repository describes itself as: Firmware for Xteink X3/X4. Personal fork of Crosspoint and CrossInk. The licence is MIT.
When your agent uses it
- Touching storage
- Any code that could reach into the SDK
Example prompts
- “/hal-and-abstractions”
What it can do on your machine
Read from SKILL.md and the folder at commit d272143. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Hal And Abstractions loads about 791 tokens when it runs. Until then it costs about 119 tokens; SKILL.md has 359 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- description
- Layering and abstraction discipline for the firmware. Use when touching storage, input, display, settings, i18n, or rendering, or any code that could reach into the SDK. Covers routing through the HAL (HalStorage / HalGPIO / HalDisplay) instead of raw SDK classes, MappedInputManager logical buttons instead of raw GPIO indices, UITheme/GUI for all rendering, the singleton macros, tr() for user-facing text, and where a new abstraction boundary belongs.
HAL and Abstractions
CLAUDE.md lists the HAL classes and the SdFat-concurrency reason they exist. This is when and how to route through them, and where to draw a new boundary.
Route through the layer, always
- SD card I/O:
Storage(HalStorage) andHalFile. NeverSdFat,FsFile,SdSpiCard,FsBaseFile, orSDCardManagerdirectly. The HAL serializes every SD access through one mutex; bypassing it races the SPI state machine and panics FreeRTOS (CLAUDE.md has the failure mode). This is a correctness boundary, not a style preference. - Display:
HalDisplayoverEInkDisplay. Input:HalGPIOoverInputManager. - Rendering: everything through the
GUImacro (UITheme) and the renderer's oriented metrics. No hardcoded fonts, colors, coordinates, or 800/480 literals; ask the renderer for width/height and use the oriented viewable area. - Input in activities:
MappedInputManager::Buttonlogical enums (Button::Confirm,Button::PageForward, ...). Never rawHalGPIO::BTN_*indices outsideButtonRemapActivity. Logical buttons survive user remapping and orientation; raw indices do not. - Shared state: the singleton macros (
SETTINGS,APP_STATE,GUI,Storage,I18N), not threaded pointers.
User-facing text
Every string a user reads goes through tr(STR_*). Add the key to the English
YAML, regenerate with scripts/gen_i18n.py, then use the StrId. Log lines
(LOG_*) stay hardcoded.

Drawing a new boundary
When you need an SDK capability the HAL does not expose yet, add the method to the HAL; do not reach around it. The new method inherits the mutex, logging, and error contract the rest of the HAL carries. A one-off direct SDK call in an activity is exactly the layering violation the mutex discipline cannot tolerate.
Keep abstractions thin. A wrapper that only renames an SDK call without adding the mutex, logging, or an error contract is dead weight. Add a layer only when it carries one of those contracts or hides a real implementation choice.
Self-review
- No direct SdFat / FsFile / SDCardManager / EInkDisplay / InputManager use
outside
lib/hal. - File access uses
HalFile; no.close()on a local handle (DESTRUCTOR_CLOSES_FILE); members closed inonExit. - Input uses
MappedInputManager::Button, not rawBTN_*indices. - Rendering goes through GUI/UITheme and oriented metrics; no 800/480 or hardcoded fonts/coords.
- User-facing strings use
tr(STR_*); new keys added to YAML and regenerated. - Any new SDK capability is exposed as a HAL method, not called inline.
