Memory rules for esp32/ firmware. Adapted from crosspoint-reader's heap-discipline skill to AgentDeck's multi-board reality. This is the procedure you run while writing firmware and the gate before handing it back.
Esp32 Heap Discipline is a community-contributed Claude Code skill in the knowledge-mgmt sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/esp32-heap-discipline/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use whenever writing or reviewing firmware code that allocates — new / malloc / ps_malloc / heap_caps_alloc / std::vector / std::string / String / a buffer / a cache / anything held across a render loop. Covers the PSRAM-vs-no-PSRAM board split, the allocation decision order, fragmentation avoidance, the makeUniqueNoThrow / ScopedCleanup helpers, the PROTOCOL_MAX_MSG_BYTES JSON guard, and the heap diagnostics (logHeap / [PERF] freeblk).
The Esp32 Heap Discipline Claude Code skill is built for Claude Code users and developers across all disciplines looking for general-purpose AI assistance. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 157,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
