brief

brief is a skill for Claude Code, Codex from tykisgod/quick-question. It costs 20 tokens per session (1,086 once invoked), scanned A, original, MIT.

A skill that compares the current code branch with another branch, usually develop, and creates an architecture change diagram plus a pull-request review checklist. A branch is a separate line of development, and a pull request is a proposed code change for review.

In plain words
What is it for?
Use it to review changed C# files, group changes by module, inspect commits and line counts, and prepare documents for reviewing a game-development code change.
Why use it?
It turns a large set of code changes into a structured summary, making important design changes and review tasks easier to spot.

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

brief 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 4d 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 — 144 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Respond in the user's preferred language (detect from their recent messages, or fall back to the language setting in CLAUDE.md).

Compare the current branch against develop and generate two review documents: architecture change diagram + PR review checklist.

Arguments: $ARGUMENTS

  • No arguments: compare main...HEAD
  • --base <branch>: specify a custom base branch for comparison
  • --commits: only look at the changes from the most recent commit

Execution Steps

Part 1: Collect Change Scope

  • git diff <base> HEAD --name-only | grep '\.cs$' — get all changed C# files
  • git diff <base> HEAD --diff-filter=A --name-only | grep '\.cs$' — get newly added files
  • git log <base>..HEAD --oneline — get the commit list
  • Group and count changes by module
  • Use git diff <base> HEAD --numstat to get accurate added/deleted line counts per module

Part 2: Architecture Change Diagram

Identify architectural changes, ordered from most to least significant:

Tier 1 — Cross-module contract changes

  • Interface additions/modifications under Contracts/
  • .asmdef dependency changes
  • Public enum/data structure changes
  • Global static state isolation in multi-instance scenarios
  • Check anti-patterns defined in AGENTS.md

Tier 2 — New modules/subsystems

  • New Service modules or subdirectories
  • New Manager/Factory/Registry classes
  • New state machines or process orchestration

Tier 3 — Internal refactoring of existing modules

  • Initialization flow changes
  • Pattern changes such as singleton → dependency injection
  • Data flow direction changes

Tier 4 — Extension points/configuration changes

  • New interface implementations
  • Config structure changes
  • New events/callbacks

Draw a Mermaid diagram for each Tier:

  • Module dependency changesgraph LR, color-coded: new (green) / modified (orange) / deleted (red)
  • Data flow / lifecyclesequenceDiagram or flowchart
  • State machinesstateDiagram-v2
  • Class relationshipsclassDiagram

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.

brief is a skill published in the GitHub repository tykisgod/quick-question (11 stars, last pushed 9d ago), licensed MIT. It adds 20 tokens to every session and 1,086 once invoked, about $0.0001 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 2026-08-30.
