tour: Skill for Claude Code

.agents/skills/grill-me/SKILL.md

grill-me is a skill for Claude Code, Codex from a9a4k/tour. It costs 49 tokens per session (129 once invoked), scanned A, a copy of cross-examine, MIT.

A guided interview that examines a software plan or design one decision at a time. It keeps asking questions until the important choices and dependencies are understood.

In plain words
What is it for?
Use it to stress-test a plan or design, with a recommended answer for each question; it explores the codebase first when the code can answer the question.
Why use it?
It exposes unclear assumptions and unresolved branches before implementation begins, reducing the chance of building the wrong thing.

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is a9a4k/tour's own configuration. It tells Claude Code and Codex how to work on tour 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 tour configures →

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

grill-me 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 9d 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.

Origin

This is a copy

88% identical to cross-examine — 4 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

Interview me relentlessly about every aspect of this plan until we reach a shared understanding. Walk down each branch of the design tree, resolving dependencies between decisions one-by-one. For each question, provide your recommended answer.

Ask the questions one at a time.

If a question can be answered by exploring the codebase, explore the codebase instead.

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.
