What it does

Architecture Review is an agent skill from proflead/codex-skills-library. Review a system architecture for scalability, reliability, and maintainability. Use when a senior developer needs to critique a design.

Its SKILL.md is about 200 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development, covering Software architecture. The repository describes itself as: Codex Skills Library is a curated library of reusable Codex skills for developers, individuals, and teams.

When your agent uses it

  • A senior developer needs to critique a design
  • Tasks that involve Software architecture

Example prompts

  • “/architecture-review”

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. Validate alignment with requirements and constraints.
  2. Identify bottlenecks, single points of failure, and data risks.
  3. Recommend improvements and tradeoff decisions.

What it can do on your machine

Read from SKILL.md and the folder at commit a05260c. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Architecture Review loads about 199 tokens when it runs. Until then it costs about 39 tokens; SKILL.md has 72 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~39
When it runs · the whole SKILL.md, loaded when a task matches
~199

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 72 words (~199 tokens).
