description

Synchronize Veil headers with the latest phnt (Process Hacker Native API) changes. Use this skill whenever the user wants to update Veil from upstream phnt, sync NT kernel headers, apply phnt diffs, convert PHNT macros to NTDDI macros, add __kernel_entry/Zw* function pairs, or generally keep Veil in step with winsiderss/systeminformer. Also use when the user mentions "update Veil", "sync phnt", "apply phnt changes", "VERSION_COMMIT", or asks to refresh Veil headers from upstream.

Veil Update Skill

Overview

Veil is a Windows native API header library that synchronizes with phnt and adapts it to Veil's coding conventions.

Prerequisites

Component	Value
Build script	BuildAllTargets.cmd in Veil.Test/
Pre-build cleanup	Kill zombie MSBuild: taskkill /f /im MSBuild.exe
Current upstream	Read VERSION_COMMIT (root, hash only)

Update Workflow

Phase 1 — Prepare

1. Read VERSION_COMMIT for the current upstream commit hash.
2. Sparse-clone or pull winsiderss/systeminformer into .cache/systeminformer/.
3. Run git diff <old> <new> -- phnt/include/ to generate per-file diffs.
4. Identify which phnt files changed and map them to Veil headers (see File Mapping).

Phase 2 — Apply

For each changed phnt file that has a Veil mapping:

1. Read the diff section and the latest phnt source.
2. Read the current Veil header.
3. Apply new additions (functions, structs, enums, macros, typedefs) that don't already exist in Veil.
4. Do not remove existing Veil content — only add or update.
5. Handle each change type as described below.

Phase 3 — Convert

Macro Conversion

Replace all PHNT_* macros with Veil equivalents:

phnt Macro	Veil Macro
PHNT_VERSION	NTDDI_VERSION
PHNT_WINDOWS_OLDEST	NTDDI_WIN2K
PHNT_WINDOWS_XP	NTDDI_WINXP
PHNT_WINDOWS_SERVER_2003	NTDDI_WS03
PHNT_WINDOWS_VISTA	NTDDI_VISTA
PHNT_WINDOWS_7	NTDDI_WIN7
PHNT_WINDOWS_8	NTDDI_WIN8
PHNT_WINDOWS_8_1	NTDDI_WINBLUE
PHNT_WINDOWS_10	NTDDI_WIN10
PHNT_WINDOWS_10_TH2	NTDDI_WIN10_TH2
PHNT_WINDOWS_10_RS1	NTDDI_WIN10_RS1
PHNT_WINDOWS_10_RS2	NTDDI_WIN10_RS2
PHNT_WINDOWS_10_RS3	NTDDI_WIN10_RS3
PHNT_WINDOWS_10_RS4	NTDDI_WIN10_RS4
PHNT_WINDOWS_10_RS5	NTDDI_WIN10_RS5
PHNT_WINDOWS_10_19H1	NTDDI_WIN10_19H1
PHNT_WINDOWS_10_19H2	NTDDI_WIN10_19H1
PHNT_WINDOWS_10_20H1	NTDDI_WIN10_VB
PHNT_WINDOWS_10_20H2	NTDDI_WIN10_MN
PHNT_WINDOWS_10_21H1	NTDDI_WIN10_FE

Example:

// phnt:        #if (PHNT_VERSION >= PHNT_WINDOWS_10_RS1)
// Veil after:  #if (NTDDI_VERSION >= NTDDI_WIN10_RS1)

Nt Function Formatting

Add __kernel_entry before NTSYSCALLAPI for all Nt* syscall declarations. Ensure the closing ); has no leading spaces.

Before (phnt):

NTSYSCALLAPI
NTSTATUS
NTAPI
NtFlushKey(
    _In_ HANDLE KeyHandle
    );

After (Veil):

__kernel_entry NTSYSCALLAPI
NTSTATUS
NTAPI
NtFlushKey(
    _In_ HANDLE KeyHandle
);

Zw Function Pair

Immediately after each Nt* function, add the corresponding Zw* function:

_IRQL_requires_max_(PASSIVE_LEVEL)
NTSYSAPI
NTSTATUS
NTAPI
ZwFlushKey(
    _In_ HANDLE KeyHandle
);

Use _IRQL_requires_max_(PASSIVE_LEVEL) and NTSYSAPI for Zw functions.

Other Conversions

• static_assert → STATIC_ASSERT
• Replace phnt-style _Kernel_entry_ → Veil __kernel_entry
• Sync Zw parameter annotation fixes from upstream when applicable

Phase 4 — Validate

After each file update, run the build:

taskkill /f /im MSBuild.exe
Veil.Test/BuildAllTargets.cmd

Fix compilation errors before proceeding to the next file.

Phase 5 — Finalize

1. Update VERSION_COMMIT with the new upstream commit hash (hash only, no URL or date).
2. Report changes from ntmisc.h separately to the user.
3. Clean up .cache/ directory.

Code Conventions

File Header

Every Veil header starts with:

/*
 * PROJECT:   Veil
 * FILE:      Veil.System.<Module>.h
 * PURPOSE:   This file is part of Veil.
 *
 * LICENSE:   MIT License
 *
 * DEVELOPER: MeeSong ([e-mail])
 */

typedef enum _ENUM_NAME

Verification Checklist

• All PHNT_WINDOWS_* macros converted to NTDDI_*
• All Nt* functions have __kernel_entry attribute
• All Nt* functions have corresponding Zw* pairs
• Closing parentheses aligned (no leading spaces before );)
• No compilation errors in BuildAllTargets.cmd
• Definition order respects dependencies
• ntmisc.h changes reported separately
• VERSION_COMMIT updated
• .cache/ cleaned up

Error Handling

Issue	Cause	Solution
Undefined type	Missing dependency	Check definition order; move definition earlier
Redefinition	Duplicate in SDK/WDK	Wrap with #ifndef _KERNEL_MODE or version check
Missing SAL annotation	phnt inconsistency	Add _In_, _Out_, _Inout_ as appropriate
Macro conflict	Name collision	Use VEIL_ prefix or conditional compilation
