rosetta-grill

rosetta-grill is a command for Claude Code from tjboudreaux/rosetta. It costs 82 tokens per session (1,023 once invoked), scanned A, original, MIT.

A command that questions a software plan or design and records the final decision as an ADR or PDR, which are documents that preserve why a technical choice was made. It bases its questions on existing decisions and the current code.

In plain words
What is it for?
Use it to challenge an architecture or implementation plan, resolve conflicts with existing decisions, and save the outcome as a durable decision record.
Why use it?
It prevents important design discussions from being forgotten and avoids reopening decisions that are already settled without checking the project’s records and code.

Command for Claude Code

Written for Claude Code: allowed-tools in frontmatter. Also seen: names the TodoWrite tool.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is python3 scripts/decisions.py resolve --root decisions --text "<topic terms>".

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

rosetta-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 8d 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.

/rosetta-grill — grounded interrogation that produces a decision record

grill-me interrogates a plan from scratch. rosetta-grill does it grounded in what's already decided and what the code actually does, and closes the loop by writing the resolved decision into the library — so the conversation produces a durable, code-anchored ADR/PDR instead of evaporating.

Workflow

1. Ground in the resolved decision state (don't re-litigate settled decisions)

Before asking anything, resolve the current state for the topic so questions are informed, not naive:

  • Locate the decision library (./decisions or run rosetta first if none exists).
  • For the topic terms, run the resolver — this returns the current decision(s), follows supersession, and flags conflicts:
    python3 scripts/decisions.py resolve --root decisions --text "<topic terms>"
    python3 scripts/decisions.py search  --root decisions --text "<topic terms>" --status Accepted
    
  • Read any existing .agents/ground-truth.md for the verified current state.
  • git log --oneline -20 + read the code the topic touches — code/git is the truth hierarchy's top authority (SKILL.md step 6). A plan that contradicts current code must justify the change.

Open by stating what's already settled: "ADR 0042 (Accepted) makes X the current approach, and foo.py confirms it. Are you changing that? If so this will supersede 0042." If resolve returns a conflict (≥2 current records), surface it first — that's the highest-value thing to resolve.

2. Grill — one question at a time, recommendation-first, grounded

Walk the decision tree, resolving dependencies one-by-one (the grill-me discipline). For each question:

  • Give your recommended answer and the reasoning.
  • Anchor it to the resolved state: cite the ADR/code it agrees-with or would-supersede.
  • If a question is answerable from the codebase or the decision library, answer it yourself (Read/ Grep/decisions.py get) instead of asking.
  • Push on: unstated assumptions, what it supersedes, scope (subsystem/region/tier — Rosetta evals show decisions are often conditional), reversibility, and how you'd verify it in code/git later.

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.

rosetta-grill is a command published in the GitHub repository tjboudreaux/rosetta (2 stars, last pushed 1mo ago), licensed MIT. It adds 82 tokens to every session and 1,023 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
