What it does

Arch Wiki is an agent skill from ahmedemad3/arch-wiki. Scans any project codebase for new/changed modules, endpoints, middleware, infrastructure, Docker topologies, SQL queries, or permissions and updates docs/architecture/architecture.json. Then regenerates docs/architecture/architecture.html by running buildhtml.py. Use this after any feature addition, module change, route update, SQL query, or architecture modification — for any backend framework (Express, NestJS, FastAPI, Django, Rails, Laravel, Spring, etc.).

Its SKILL.md is about 5.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 83 other files (for example `.github/workflows/test.yml`, `README.md` and `bin/install.js`).

It sits in Backend & APIs, covering Backend development and SQL. It works with SQL, Docker, OpenAPI and Django.

What it can do on your machine

Read from SKILL.md and the folder at commit 1109433. 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
Ships script files (Python and JavaScript, from the files we listed), which the agent can run.
Shell commands in SKILL.md call:
- python
- pip
- docker
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use pip and docker, which can reach the network depending on how they are called.
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

Arch Wiki loads about 5.1k tokens when it runs. Until then it costs about 119 tokens; SKILL.md has 1,558 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~119
When it runs · the whole SKILL.md, loaded when a task matches: ~5.1k

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 1,558 words (~5,091 tokens).
