tutti: Skill for Codex

.codex/skills/tutti-architecture-review/SKILL.md

tutti-architecture-review is a skill for Codex from tutti-os/tutti. It costs 48 tokens per session (2,036 once invoked), scanned A, original, Apache-2.0.

A focused architecture review skill for changes in the Tutti codebase. It examines project structure, which modules own which responsibilities, how modules are layered, and whether duplicate event-handling infrastructure exists.

In plain words
What is it for?
Use it to review a Git diff or a named module for interface and implementation placement, layering, module ownership, and duplicated event-center code.
Why use it?
It helps catch structural problems in changed code without turning the review into a general search for every possible bug.

Skill for Codex

Written for Codex: agents/openai.yaml present. Also seen: mentions subagents; mentions AGENTS.md; mentions Codex.

This is tutti-os/tutti's own configuration. It tells Codex how to work on tutti 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 tutti configures →

About the project

Tutti is a real-time collaboration space where people can work alongside multiple AI agents, including by sharing rooms, editing together, and borrowing agents. It is intended for users who want human-agent or multi-agent collaboration across devices, with open-source and VM versions available. The catalogue entries provide skills and instructions for working with Tutti.

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

tutti-architecture-review 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 13d ago.

The scan reads SKILL.md. This mod also ships 4 executable files (scripts/build-review-scope.mjs, scripts/build-review-scope.test.mjs, scripts/plan-review.mjs, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Tutti Architecture Review

Use this skill when reviewing a tutti change or a named module for repository structure, module ownership, or layering compliance. This is a focused architecture review, not a general bug hunt.

Vocabulary

Use the architecture vocabulary consistently:

  • Module: anything with an interface and an implementation.
  • Interface: everything a caller must know to use the module correctly.
  • Implementation: the code inside a module.
  • Depth: leverage at the interface; deep modules hide useful behavior behind a small interface.
  • Seam: where an interface lives.
  • Adapter: a concrete thing satisfying an interface at a seam.
  • Leverage: what callers get from depth.
  • Locality: what maintainers get from depth.

Prefer these words in findings. Avoid vague substitutes such as "component", "service", "utility", or "boundary" when a vocabulary term fits.

Workflow

  1. Resolve the user's review intent:

    • plain git diff review for the current change
    • module-focused diff review when the user names a module inside the current change
    • static module review when the user wants a named module inspected even without current diff overlap

    Use light natural-language guidance when the request is ambiguous. Do not force the user through a fixed mode menu.

  2. When the user names a module, let the main agent infer a few candidate path keywords and gather candidate paths. Then normalize those paths into a scope file:

    node ./.codex/skills/tutti-architecture-review/scripts/build-review-scope.mjs \
      --input /tmp/tutti-review-candidates.json \
      --output /tmp/tutti-review-scope.json
    

    Candidate input is agent-produced. The script does not invent module keywords or search the repository itself; it only normalizes candidate paths into a stable scope contract for the planner.

    Read references/scope-contract.md when changing or consuming the candidate input, normalized scope output, or planner scope metadata.

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.
