windbg-user-virtual-memory-exhaustion SKILL.md skillA
windbg-user-virtual-memory-exhaustion from microsoft/win-dev-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add microsoft/win-dev-skills/windbg-user-virtual-memory-exhaustion@git:20261007.790b577Pins git:20261007.790b577 in mdr.lock. Pin the fingerprint instead.

Use when a native app, service, or user-mode driver host allocation fails; distinguish VA exhaustion, fragmentation, and commit pressure. Not for managed .NET heap growth, proving a leak from one snapshot, or corruption.
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
# Virtual Memory Exhaustion **Load `windbg-diagnostic-method` first** if it is not already loaded in this conversation, and apply it throughout for evidence ranking, hypothesis testing, confidence calibration, independent review, and report validation. This skill adds the bug-family-specific commands and evidence requirements. ## Detection Investigate `E_OUTOFMEMORY` (`0x8007000E`), `STATUS_NO_MEMORY` (`0xC0000017`), `bad_alloc`, or failed heap/virtual allocations in an application, service, or user-mode driver host (including UMDF). Record the actual API, requested size/alignment, architecture, flags, and error. Free physical RAM does not rule out insufficient virtual address space, commit pressure, or applicable limits. ## Workflow ### 1. Examine the process VA map ```text !address -summary !address !heap -s ``` Compare available regions with the attempted allocation's contiguous range and alignment requirements. Distinguish reserved, committed, free, image, mapped, stack, and heap ranges. A large reservation consumes VA without committing its entire range. Heap internals may require more than the user's requested bytes. …

How to install
mdr add microsoft/win-dev-skills/windbg-user-virtual-memory-exhaustion@sha256:281202874f7af2f8The line at the top of this page pins the label git:20261007.790b577, 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.
