grill

grill is a skill for Claude Code, Codex from ntorga/agent-starter-kit. It costs 33 tokens per session (1,174 once invoked), scanned A, original, MIT.

A question-and-answer planning process that interviews the user in rounds before work begins. It explores business needs and, depending on the chosen path, technical and implementation details.

In plain words
What is it for?
It helps produce a design tree, acceptance plan, architecture notes, and implementation tasks for a feature.
Why use it?
It reduces misunderstandings by settling important decisions with the user before the coding work starts.

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

grill 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 2d 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.

How it starts

The opening of the file, as written. The whole thing — 69 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Purpose

Reach shared understanding with the user before execution. The Architect owns the design tree — the decisions the feature must settle, mapped with dependencies, pruned by path, ranked by impact. You work the frontier in rounds: ask up to 5 frontier questions, wait for the user's answers, transcribe the settled decisions into the artifacts. After the user confirms, execution is autonomous. The user is bothered in rounds, not on every micro-delivery.

Procedure

The path determines which branches the tree explores. Step 1 resolves it from long-term memory, or asks the user when none is recorded:

  • Beginner — business questions only. The Architect infers architecture from the maintenance, lightweight, and safe principles (KISS, single responsibility, safe boundaries — rules/code/general.md). Ceiling: 30 business questions.
  • Tinkerer — business and architecture questions. Ceiling: 30 business, 10 architecture.
  • Pro — business, architecture, and implementation questions. Ceiling: 100 questions per branch.

Artifacts live at .memory/plan/<feature-slug>/:

  • tree.md — the design tree. The Architect owns it.
  • plan.md — acceptance criteria, from the settled business decisions.
  • arch.md — directory structure, layer separation, reference projects. Tinkerer and pro. Beginner gets defaults.
  • impl.md — epics grouped at one day of work, with parallelizable groups.

You transcribe plan.md, arch.md, and impl.md as decisions settle. The Architect owns tree.md and the grounded impl.md.

  1. Select path. Check long-term memory (uses: skills/agent-memory/SKILL.md) for a recorded grill path under ## Preferences. If one exists, proceed with it — state the path in the first message to the user so they can override in one word. If the user overrides, replace the recorded entry. If none exists, ask the user to choose: beginner, tinkerer, or pro. Record the choice under ## Preferences as [grill] path: <beginner | tinkerer | pro>.
  2. Build the tree. Dispatch the Architect (personas/architect.md) (follows: skills/dispatch/SKILL.md) in tree mode with the selected path. The Architect writes tree.md.
  3. Work the frontier in rounds. The frontier is every open node in tree.md whose dependencies are all settled. Send up to 5 frontier questions per round, ordered by impact. Each question carries the tree's recommendation. Wait for the user's answers before the next round.

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.
