heatshrink Integration

Overview

Use this skill to integrate heatshrink (github.com/atomicobject/heatshrink) by fixing memory budget, window_sz2/lookahead_sz2 sizes, the sink/poll/finish streaming loop, and decompression safety. Compression bugs usually come from mismatched encoder/decoder settings, an unfinished poll loop, or output buffers that are too small.

When To Use

Use this skill when:

• The user wants heatshrink compression/decompression on an MCU.
• The task involves compressed logs, resources, firmware chunks, OTA payloads, or serial transfer compression.
• Decompression fails, output is truncated, memory is too high, or compressed data is incompatible.
• The project uses heatshrink_encoder.h, heatshrink_decoder.h, heatshrink_config.h, or the heatshrink command-line tool.

Do not use this skill for general archive formats like gzip/zip unless heatshrink is specifically involved.
