Install
Works with every agent the skills CLI supports.
npx skills add https://github.com/hkuds/cli-anything --skill cli-anything-renderdoc- 01
Install
Run the command in your project. The CLI asks which agents to install for.
- 02
Describe the task
Ask your agent for something this skill covers. It loads cli-anything-renderdoc automatically when relevant.
- 03
Review the result
The agent follows the SKILL.md steps, scripts and references bundled with the skill.
SKILL.md
The instructions your agent reads when the skill is triggered.
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
capture
cli-anything-renderdoc -c frame.rdc capture info # Metadata + sections
cli-anything-renderdoc -c frame.rdc capture thumb -o t.png # Extract thumbnail
cli-anything-renderdoc -c frame.rdc capture convert -o out.rdc --format rdc
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 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
cli-anything-renderdoc -c frame.rdc resources read-buffer <id> --format float32
mesh
cli-anything-renderdoc -c frame.rdc mesh inputs 42 --max-vertices 10
cli-anything-renderdoc -c frame.rdc mesh outputs 42
counters
cli-anything-renderdoc -c frame.rdc counters list
cli-anything-renderdoc -c frame.rdc counters fetch --ids 1,2,3
Preview Bundles
RenderDoc preview support is for truthful capture inspection rather than live creative preview.
# List preview recipes
cli-anything-renderdoc -c frame.rdc --json preview recipes
# Capture a preview bundle for the active capture or a specific event
cli-anything-renderdoc -c frame.rdc --json preview capture --recipe quick --event-id 42
# Capture a diff preview bundle for two events or captures
cli-anything-renderdoc -c frame.rdc --json preview diff 100 200
cli-anything-renderdoc -c a.rdc --json preview diff 100 200 --capture-b b.rdc
# Return the latest existing bundle for the capture
cli-anything-renderdoc -c frame.rdc --json preview latest --recipe quick
Typical preview bundle contents:
- capture thumbnail
- output-target images
pipeline_state.jsonaction_summary.json
Diff bundles additionally include:
- A/B thumbnails
- A/B output-target images
pipeline_diff.json
RenderDoc does not currently expose live preview sessions. Instead, each
capture/diff bundle appends to a stable recipe-level trajectory.json.
Viewer commands:
cli-hub previews inspect /path/to/bundle
cli-hub previews html /path/to/bundle -o page.html
cli-hub previews open /path/to/bundle
JSON Mode
All commands support --json for machine-readable output:
cli-anything-renderdoc -c frame.rdc --json actions summary
Environment Variables
| Variable | Description |
|---|---|
RENDERDOC_CAPTURE | Default capture file path |
PYTHONPATH | Must include RenderDoc path |
Agent Usage Notes
- Use
pipeline shader-exportto 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)
- D3D11 → DXBC binary, exported as embedded HLSL source (
- Use
pipeline diffto compare two events — it writes a JSON file and prints only the path; use-bfor a second capture - Always specify
--jsonfor programmatic consumption - Use
actions summaryfirst to understand capture complexity - Use
actions list --draws-onlyto focus on actual rendering - Use
preview captureorpreview diffwhen the agent needs a portable, honest inspection bundle rather than raw replay calls alone - Read
_trajectory_pathfrom preview JSON if you need persistent capture/diff history - Use
cli-hub previews ...only to inspect/open already-generated bundles - 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
