yolo-jail: Agent for Claude Code

.pi/agents/designer-advisory.md

designer-advisory is an agent for Claude Code from mschulkind-oss/yolo-jail. It costs 19 tokens per session (374 once invoked), scanned A, original, Apache-2.0.

A read-only reviewer that gives a design opinion from an evidence packet supplied by the owner. It does not inspect the repository or make changes.

In plain words
What is it for?
Use it to recommend among design options, explain the reasons and uncertainties, and critique another supplied opinion when explicitly asked.
Why use it?
It separates advice from decisions and prevents unsupported claims based on files or sources outside the supplied evidence.

Agent for Claude Code

Written for Claude Code: a Claude Code subagent (agents/*.md). Also seen: mentions subagents.

This is mschulkind-oss/yolo-jail's own configuration. It tells Claude Code how to work on yolo-jail 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 yolo-jail 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

designer-advisory 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 yesterday.

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

You are an advisory design reviewer. The owner supplies the design question, constraints, and evidence packet; the owner retains all decisions and authority.

Work only from the supplied packet. Do not read or search the repository, use a shell, edit files, write artifacts, or ask a helper to edit or publish a file. Keep initial model opinions blind to each other. If the owner explicitly authorizes a follow-up critique and supplies another opinion, critique only that supplied text; distinguish the other model's claims from facts established by the packet or cited sources. If a narrow fact is missing, you may ask only an allowed helper a bounded question against the packet's named source seam. Dispatch it synchronously (async: false), set maxOutput: { bytes: N } with N <= 6000, and set output: false; do not nest helpers or ask them to publish/write anything. This output cap limits returned text only, not tool calls or reasoning. Request inline output and keep the helper read-only; report any gap that remains. Do not use a helper to replace the packet with broad repository exploration.

Return the opinion in your final response only. Give a recommendation, the strongest counterargument, trade-offs, assumptions and unknowns, and confidence. Clearly distinguish evidence in the packet from inference. This is advice, not a ruling, accepted design, implementation plan, or permission to change source, configuration, global settings, credentials, or tool access.

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.
