What it does
Resource Optimization Lowend is an agent skill from mohitmishra786/low-level-dev-skills. Resource optimization skill for constrained embedded targets. Use when reducing flash/RAM usage, analyzing stack depth, reading linker map files, or tuning size vs speed on MCUs. Activates on queries about firmware size optimization, linker map, stack usage, -Os, flash RAM budget, or bloat analysis.
Its SKILL.md is about 820 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 Development. It works with Rust. The repository describes itself as: A curated suite of AI agent skills for systems and low-level programming with C/C++, Rust, and Zig toolchains, covering compilers, debuggers, profilers, build systems…. The licence is MIT.
When your agent uses it
- Reducing flash/RAM usage
- Analyzing stack depth
- Reading linker map files
- Tuning size vs speed on MCUs
Example prompts
- “/resource-optimization-lowend”
Workflow steps
7 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit bdc5847. 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 (its code samples are bash, ld and makefile).
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
Resource Optimization Lowend loads about 821 tokens when it runs. Until then it costs about 82 tokens; SKILL.md has 231 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
- Resource optimization skill for constrained embedded targets. Use when reducing flash/RAM usage, analyzing stack depth, reading linker map files, or tuning size vs speed on MCUs. Activates on queries about firmware size optimization, linker map, stack usage, -Os, flash RAM budget, or bloat analysis.
Resource Optimization (Low-End Systems)
Purpose
Guide agents through flash and RAM optimization on constrained devices: compiler size flags, linker map analysis, stack usage measurement, dead code elimination, and size-vs-speed tradeoffs — for bare-metal and small RTOS images.
When to Use
- Firmware exceeds flash budget
- Stack overflow in production only
- Choosing
-Osvs-O2on MCU - Finding unexpected
.rodataor.bssgrowth
Workflow
1. Size measurement toolchain
arm-none-eabi-size -A firmware.elf
arm-none-eabi-objdump -h firmware.elf
nm --size-sort -S firmware.elf | tail -202. Linker map file
/* linker.ld */
OUTPUT_FORMAT("elf32-littlearm")
ENTRY(Reset_Handler)
SECTIONS
{
/* ... */
}
/* Generate map */
/* gcc ... -Wl,-Map=firmware.map */grep -E '\.text|\.rodata|\.data|\.bss' firmware.map | headIdentify largest symbols and unexpected library pull-in.
3. Compiler flags
| Flag | Effect |
|---|---|
-Os | Size-first optimization |
-ffunction-sections -fdata-sections | Per-symbol sections |
-Wl,--gc-sections | Drop unused sections |
-flto | Cross-TU dead code elimination |
-specs=nano.specs | Smaller newlib (GCC ARM) |
CFLAGS += -Os -ffunction-sections -fdata-sections
LDFLAGS += -Wl,--gc-sections -Wl,--print-memory-usage4. Stack analysis
# Static (if built with -fstack-usage)
find . -name '*.su' -exec cat {} \;
# Linker stack symbol
grep _estack firmware.mapRuntime: fill stack with pattern (0xDEADBEEF), run tests, scan high-water mark. FreeRTOS: uxTaskGetStackHighWaterMark.
5. RAM categories
| Section | Tactic |
|---|---|
.bss | Shrink buffers; pool allocators |
.data | Move const to flash (const → .rodata) |
| Heap | Avoid malloc; fixed pools |
| Stack | Reduce nesting; smaller ISR stacks |
6. Size vs speed decision
Hot path in ISR or 1 kHz loop?
├── Yes → -O2 for that file (#pragma GCC optimize)
└── No → -Os globally7. Agent usage
/resource-optimization-lowend Find top 10 flash consumers in firmware.map and suggest -gc-sections fixesCommon Problems
| Symptom | Cause | Fix |
|---|---|---|
| printf pulls 20+ KB | Full newlib printf | _write retarget; tiny printf |
--gc-sections broke IRQ | Section collected | KEEP() in linker script |
| Stack overflow late | Deep call + IRQ nest | Measure HW stack; increase _estack |
| RAM zero but big ELF | .data not loaded | Check VMA/LMA |
| LTO link fail | Mixed compiler versions | Same GCC for all objects |
