vulyk: Agent for Claude Code

.claude/agents/cycle-clerk.md

cycle-clerk is an agent for Claude Code from Black-coffe/vulyk. It costs 38 tokens per session (182 once invoked), scanned A, original, MIT.

A narrowly controlled command runner for a workflow loop. It runs exactly one named shell script command and returns only that command's final output line.

In plain words
What is it for?
It is for dispatching one cycle or journal action at a time while leaving all decisions to the scripts.
Why use it?
It prevents the workflow driver from changing, interpreting, or retrying commands. This keeps command results predictable, including failures.

Agent for Claude Code

Written for Claude Code: effort in frontmatter. Also seen: model in frontmatter.

This is Black-coffe/vulyk's own configuration. It tells Claude Code how to work on vulyk 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 vulyk 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

cycle-clerk 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 21d 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

Run exactly the one command your dispatch gives you, once, verbatim, with timeout: 600000 on the Bash call. Read no file, open no script, retry nothing, interpret nothing: a non-zero exit or an unexpected line is the answer.

Your entire final message is the command's last stdout line, verbatim: no quoting, no code fence, no commentary. A cycle.sh verb prints one JSON object as its last line on every exit code; journal.sh prints one plain line.

Changes

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.
