Memory Leak Diagnosis Skill SKILL.md skillA
Memory Leak Diagnosis Skill from fal3/claude-skills-collection is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Diagnose, explain, and fix Swift and Apple-platform memory leaks, unexpected object retention, deinit failures, heap growth, retain cycles, runaway caches, task and AsyncSequence lifetimes, timer/delegate/closure ownership, jetsam, and ARC issues using Xcode Memory Graph and Instruments Allocations, Leaks, and VM tools. Use when objects do not deallocate, memory rises across repeated workflows, or weak/unowned and capture-list choices are unclear. Do not enable Zombies for leak measurement…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Swift Memory Diagnosis Prove the lifetime bug before changing capture lists. “Memory grew,” “deinit has not run yet,” “an object is retained,” and “an allocation is leaked” describe different evidence. ## Compatibility baseline ARC, weak references, and Xcode’s core memory tools apply across currently supported Swift/Apple-platform projects. State version requirements for the specific APIs in the inspected code: - Structured concurrency and `Task` require Swift 5.5 and the corresponding platform concurrency runtime. - The task example in this skill uses duration-based sleep, available with Swift 5.7-era toolchains and iOS 16 / macOS 13. - Observation, SwiftData, Combine, and framework-specific lifetime rules depend on the app’s declared deployment targets. - Xcode and Instruments UI labels change. Describe goals and inspected relationships, not assumed arrow colors or displayed reference-count numbers. ## Classify the symptom | Observation | Likely category | Best first tool | | --- | --- | --- | | A dismissed screen remains reachable | Unwanted retention / ownership bug | Memory Graph | …

How to install
mdr add fal3/claude-skills-collection/Memory Leak Diagnosis Skill@sha256:77a7d3861f01afdfThe line at the top of this page pins the label git:20260814.a9c26d7, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
