RenderDoc CLI Skill

Headless command-line analysis of RenderDoc GPU frame captures (

.rdc
files).

Capabilities

  • Capture inspection: metadata, sections, thumbnails, format conversion
  • Action tree: list/search/filter draw calls, clears, dispatches, markers
  • Texture operations: list, inspect, export (PNG/JPG/DDS/HDR/EXR), pixel picking
  • Pipeline state: full shader/RT/viewport state at any event
  • Shader analysis: export shader in human-readable form (HLSL/GLSL/disasm), constant buffer readback
  • Resource inspection: buffer/texture enumeration, raw data reading
  • Mesh data: vertex shader input/output decoding
  • GPU counters: enumerate and fetch hardware performance counters

Command Groups

actions

cli-anything-renderdoc -c frame.rdc actions list           # All actions
cli-anything-renderdoc -c frame.rdc actions list --draws-only  # Draw calls only
cli-anything-renderdoc -c frame.rdc actions summary        # Counts by type
cli-anything-renderdoc -c frame.rdc actions find "Shadow"  # Search by name
cli-anything-renderdoc -c frame.rdc actions get 42         # Single action

textures

cli-anything-renderdoc -c frame.rdc textures list
cli-anything-renderdoc -c frame.rdc textures get <id>
cli-anything-renderdoc -c frame.rdc textures save <id> -o out.png --format png

cli-anything-renderdoc -c frame.rdc textures pick <id> 100 200

pipeline

cli-anything-renderdoc -c frame.rdc pipeline state 42

# Export shader in human-readable form
# Text shaders (GLSL/HLSL) → saved directly
# Binary shaders (DXBC/SPIR-V) → embedded source (HLSL/GLSL) or disassembly
cli-anything-renderdoc -c frame.rdc pipeline shader-export 42 --stage Fragment
cli-anything-renderdoc -c frame.rdc pipeline shader-export 42 --stage Vertex -o ./shaders/

cli-anything-renderdoc -c frame.rdc pipeline cbuffer 42 --stage Vertex --index 0

# Compare pipeline state between two events
# Default output: same directory as the capture file  ;  use -o to override
cli-anything-renderdoc -c a.rdc pipeline diff 100 200 -b b.rdc
cli-anything-renderdoc -c frame.rdc pipeline diff 100 200              # same capture
cli-anything-renderdoc -c a.rdc pipeline diff 100 200 -b b.rdc -o result.json
cli-anything-renderdoc -c a.rdc pipeline diff 100 200 -b b.rdc --no-compact

resources

cli-anything-renderdoc -c frame.rdc resources list
cli-anything-renderdoc -c frame.rdc resources buffers

counters

cli-anything-renderdoc -c frame.rdc counters list
cli-anything-renderdoc -c frame.rdc counters fetch --ids 1,2,3

JSON Mode

All commands support

--json
for machine-readable output:

Environment Variables

VariableDescription
RENDERDOC_CAPTURE
Default capture file path
PYTHONPATH

Agent Usage Notes

  • Use
    pipeline shader-export
    to extract shaders
    — for binary shaders (DXBC/SPIR-V) it auto-exports embedded HLSL/GLSL source or falls back to disassembly; for text shaders (GLSL/HLSL) it saves the raw source directly
  • Shader formats by capture API:
    • D3D11 → DXBC binary, exported as embedded HLSL source (
      .hlsl
      ) or bytecode asm (
      .dxbc.asm
      )
    • OpenGL/GLES → GLSL source text (
      .glsl
      ), already human-readable
    • Vulkan → SPIR-V binary, exported as embedded GLSL source (
      .glsl
      ) or SPIR-V asm (
      .spv.asm
      )
  • Use
    pipeline diff
    to compare two events
    — it writes a JSON file and prints only the path; use
    -b
    for a second capture
  • Always specify
    --json
    for programmatic consumption
  • Use
    actions summary
    first to understand capture complexity
  • Use
    actions list --draws-only
    to focus on actual rendering
  • Pipeline state requires an event ID from the action list
  • Texture save supports: png, jpg, bmp, tga, hdr, exr, dds
  • Buffer data can be decoded as hex, float32, uint32, or raw bytes
