5chan: Agent for Claude Code

.claude/agents/profiler.md

profiler is an agent for Claude Code from bitsocialnet/5chan. It costs 22 tokens per session (327 once invoked), scanned A, original, GPL-3.0.

An automated performance investigator for web pages that measures loading speed and detects unnecessary React re-rendering. React is a JavaScript framework for building user interfaces.

In plain words
What is it for?
Use it to profile groups of web pages, collect Web Vitals, inspect React rendering, and return a structured list of issues.
Why use it?
It helps locate slow routes and inefficient interface updates that are difficult to spot by reading code alone.

Agent for Claude Code

This is bitsocialnet/5chan's own configuration. It tells Claude Code how to work on 5chan itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything 5chan configures →

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

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 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 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.
