Install
Works with every agent the skills CLI supports.
npx skills add https://github.com/wedsamuel1230/embedded-engineering-skills --skill memory-budgeting- 01
Install
Run the command in your project. The CLI asks which agents to install for.
- 02
Describe the task
Ask your agent for something this skill covers. It loads memory-budgeting automatically when relevant.
- 03
Review the result
The agent follows the SKILL.md steps, scripts and references bundled with the skill.
SKILL.md
The instructions your agent reads when the skill is triggered.
Memory Budgeting
Make memory a measured budget, not a nominal board label. The implementation is embedded C/C++; scripts may parse build or runtime logs when that is the useful deterministic tool.
Intake
Record exact board/module, flash/RAM/EEPROM/PSRAM, bootloader and partition layout, framework, compiler flags, libraries, static buffers, task stacks, filesystem/OTA needs, peak protocol sizes, and available measurement output.
Process
- Separate static data, code/flash, heap, task stacks, interrupt state, filesystem, bootloader, and OTA/update slots.
- Establish a numeric budget and minimum margin for every category. Use board references rather than copying a family-level number into a project claim.
- Capture compiler size output and map changes to a feature or dependency.
- Measure runtime free heap, largest block, stack high-water marks, and reset/ allocation failures under representative load where the framework exposes them.
- On AVR, keep literals in flash with
F()where appropriate, prefer bounded buffers and fixed-size storage, and avoid unbounded dynamicStringuse. On ESP32/RP2040, still bound buffers and distinguish heap, stack, flash, and filesystem. - Re-run the stress case after each memory-affecting change and record the tradeoff.
Anti-rationalization
| Shortcut | Response |
|---|---|
| "The datasheet says 520 KB, so memory is fine." | Separate usable heap, stacks, reserved regions, and radio/RTOS use. |
| "It compiled." | Inspect size output and exercise runtime allocation paths. |
| "Make the buffer bigger." | Bound the protocol and prove the required maximum. |
| "Use String everywhere." | Check fragmentation and lifetime; use bounded alternatives where needed. |
| "OTA only needs the application image." | Budget both update slots, bootloader, metadata, and rollback image. |
Verification
- Build-size output and runtime memory evidence name the exact target/version.
- Each budget has a margin and a failure response.
- Stress tests cover peak message, sensor, logging, radio, and task load as applicable.
- Optimization does not remove bounds, safety checks, or recovery behavior.
Shared output contract
Use the shared Arduino skill contract: state assumptions, required tools and versions, implementation steps, tests/evidence by proof stage, known limitations, and recovery/security notes.
FAQ
What does the memory-budgeting skill do?
Use when Arduino or embedded projects hit SRAM, flash, heap, stack, partition, JSON-buffer, or performance limits, or when reviewing String use, F() placement, OTA slots, FreeRTOS stacks, or memory margin.
How do I install memory-budgeting?
Run npx skills add https://github.com/wedsamuel1230/embedded-engineering-skills --skill memory-budgeting in your project. The skills CLI detects the agents you use and copies the skill into the right folder. For Claude Code you can also place the skill folder at ~/.claude/skills/memory-budgeting/ (personal) or .claude/skills/memory-budgeting/ (project).
Which AI agents can use memory-budgeting?
Any agent that supports the open Agent Skills format (a folder with a SKILL.md file), including Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, Windsurf, Cline, OpenCode and more.
Is memory-budgeting safe to install?
No partner security audit is available yet. Skills can run commands and scripts, so read the SKILL.md and any bundled files before installing.

wedsamuel1230/embedded-engineering-skills
Build complete Arduino and embedded projects across Arduino IDE, Arduino CLI, PlatformIO, and vendor-specific toolchains. Use when users request an application combining firmware, sensors, actuators, networking, power, or deployment rather than a code snippet. The bundled scaffold targets UNO, ESP32, and Raspberry Pi Pico; use the board profile and document limitations for other targets.
arduino-code-generator
wedsamuel1230/embedded-engineering-skills
Generate Arduino and embedded C++ snippets for sensors, actuators, buses, state machines, timing, data logging, and hardware abstraction. Use when a user requests implementation code and provide the exact board, framework, toolchain, pins, voltage, memory, and library versions first. Bundled templates target UNO, ESP32, and RP2040; document unsupported board or vendor-framework behavior instead of guessing.
circuit-debugger
wedsamuel1230/embedded-engineering-skills
Systematic hardware debugging guide for Arduino/ESP32/RP2040 circuits. Use when user reports: circuit not working, components getting hot, no power, intermittent failures, unexpected behavior, sensor not responding, LED not lighting, motor not spinning. Guides through power checks, continuity testing, signal tracing, and component isolation using multimeter techniques.
arduino-serial-monitor
wedsamuel1230/embedded-engineering-skills
