What is webgpu-inspector?

A set of tools for examining WebGPU graphics work in running web pages or saved capture files. WebGPU is a browser technology for using the computer's graphics processor to draw images and run visual computations.

It is for capturing frames, inspecting graphics resources, profiling performance, and debugging WebGPU shaders and pipelines.

It helps find problems in rendered graphics, GPU pipelines, shader code, memory buffers, and textures.

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	$0.00043	$0.02350
Opus 5.5	$0.00017	$0.00940
Sonnet 5.5	$0.00009	$0.00470
Haiku 4.5	$0.00004	$0.00235

Security

Grade A, and why

webgpu-inspector 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 2mo 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 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.
