What is renderdoc-skill CLAUDE.md?

A Claude Code instruction file for connecting RenderDoc, a graphics debugging tool, with an application through its command-line interface.

It guides GPU debugging for Vulkan, Direct3D, and OpenGL applications, including frame capture and exporting images, meshes, and buffers for analysis.

It records the environment settings, capture locations, and application details needed to inspect GPU frames correctly.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00464	$0.00464
Opus 5.5	$0.00186	$0.00186
Sonnet 5.5	$0.00093	$0.00093
Haiku 4.5	$0.00046	$0.00046

Security

Grade A, and why

renderdoc-skill CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

RenderDoc + Claude Code GPU Debugging

Project Overview

This project wires Claude Code to RenderDoc via rdc-cli, enabling automated GPU frame capture, inspection, and debugging for Vulkan/D3D/GL applications.

Tools

rdc-cli (rdc): 66-command CLI wrapping RenderDoc's Python API. Installed via pip install rdc-cli.
renderdoc.pyd: Python module from RenderDoc (built from source or from an official install).

Environment

RENDERDOC_PYTHON_PATH=<path-to-renderdoc-module> — rdc-cli uses this to find renderdoc.pyd
Captures go in ./captures/ (or any directory you choose)
Analysis exports (PNGs, meshes, buffers) go in ./captures/analysis/

Your Application (customize this section)

Executable: /path/to/your/app
CWD requirement: Set CWD to your project root if the app resolves assets relative to CWD
Debug markers: List any debug markers your app emits (e.g., "Shadow Pass", "GBuffer Pass")
Scenes / modes: List any flags or scenes relevant to your app

Capture Requirements

Vulkan layer: Must be registered (see README.md for setup)
Environment: ENABLE_VULKAN_RENDERDOC_CAPTURE=1 must be set for Vulkan apps
Swapchain: The app must present frames (headless apps without vkQueuePresentKHR cannot be captured)
Capture script: See capture_frame.py for an example using the RenderDoc Python API directly

Quick Start

# Check setup
rdc doctor

# Capture a frame (adapt the capture script for your app)
python capture_frame.py

# Inspect
rdc open ./captures/my_capture.rdc
rdc info --json
rdc draws --limit 20
rdc close

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

renderdoc-skill CLAUDE.md is an instructions file published in the GitHub repository rudybear/renderdoc-skill (214 stars, last pushed 7mo ago), licensed MIT. It adds 464 tokens to every session, about $0.0019 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
