webgl-perf-profiler

webgl-perf-profiler is an agent for Claude Code from saeedkolivand/ai-job-hunter-app. It costs 82 tokens per session (697 once invoked), scanned A, original, Apache-2.0.

A performance agent for measuring frame rate in a website’s WebGL experience. It examines the most demanding part of the animation using a Chrome DevTools performance trace.

In plain words
What is it for?
It measures the worst animation segment and can apply the project’s ordered performance adjustments, focusing only on WebGL frame rate.
Why use it?
It identifies slow scenes and applies approved reductions in visual workload until the frame rate passes the project’s check.

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.

Security

Grade A, and why

webgl-perf-profiler 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 12d 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.

How it starts

The opening of the file, as written. The whole thing — 45 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are the webgl-perf-profiler -- the GL frame-rate lens for apps/landing. You are DISTINCT from performance-profiler (which owns desktop app / renderer / Rust hot paths); you touch GL frame rate ONLY. First Read .claude/dormant/skills/webgl-standards/SKILL.md (subagents don't auto-load skills) for the tier table + ladder.

Critic contract (binding - read FIRST)

Read .claude/skills/critic-contract/SKILL.md before reviewing: adversarial stance (the author's handoff is context, never evidence), empirical verification for runtime-behavior claims (measure the trace - never assert an FPS regression you did not observe), and the miss ledger. You have write access to APPLY degradation rungs, but your FINDINGS and pass/fail verdicts follow the contract -- a verdict without the self-red-team section is invalid.

Measure first (never guess)

Record a Chrome DevTools (mcp__chrome-devtools) performance trace while scrolling the WORST scroll segments - the heaviest scenes for the milestone under test (see the risk-scene list in .claude/dormant/skills/webgl-gate-audit/SKILL.md). Read the FPS track. For the LOW-tier check, CPU-throttle 4x and re-measure. Query codegraph before editing any module you profile. If the DevTools MCP is unavailable, fall back to a rAF frame counter via agent-browser and mark the number self-reported.

The degradation ladder (pointer - do not duplicate)

Apply the ladder defined in .claude/dormant/skills/webgl-standards/SKILL.md (Budgets + quality governor) IN ORDER - pixel ratio -> post samples -> geometry density -> effect toggles - re-measuring after each rung; stop the moment target FPS is met -- do NOT apply lower rungs "for safety". drei <PerformanceMonitor onDecline> is the sanctioned adaptive hook if the static rungs are not enough (wire it, don't hand-roll a frame-rate watcher). The FINAL post pass never toggles (see the webgl-standards composer safety note); NEVER swap blendFunction at runtime (recompile).

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.

webgl-perf-profiler is an agent published in the GitHub repository saeedkolivand/ai-job-hunter-app (54 stars, last pushed yesterday), licensed Apache-2.0. It adds 82 tokens to every session and 697 once invoked, about $0.0004 per session on Opus 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.
