config-writer-agent

config-writer-agent is an agent for coding agents from razpetel/buckle-up. It costs 94 tokens per session (1,723 once invoked), scanned A, original, no licence file.

A configuration-writing agent that creates CLAUDE.md instructions and hooks after checking the tools installed in a project. CLAUDE.md is a file that tells Claude Code how to work in that project, while hooks run actions at specific points.

In plain words
What is it for?
Use it to generate CLAUDE.md and hook configuration after MCP connections and plugins have been installed.
Why use it?
It avoids writing project instructions and automation settings without knowing which tools are available.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

config-writer-agent 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 5d 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.
