What it does
C4 Architecture C4 Architecture is an agent skill from aiskillstore/marketplace. Generate comprehensive C4 architecture documentation for an existing repository/codebase using a bottom-up analysis approach.
Its SKILL.md is about 4.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `skill-report.json`).
The repository describes itself as: Security-audited skills for Claude, Codex & Claude Code. One-click install, quality verified.
Example prompts
- “/c4-architecture-c4-architecture”
Requirements
- Node.js
- Docker
Workflow steps
4 steps, taken from the step headings in SKILL.md.
- Code-Level Documentation (Bottom-Up Analysis)
- Component-Level Synthesis
- Container-Level Synthesis
- Context-Level Documentation
What it can do on your machine
Read from SKILL.md and the folder at commit 44923f3. 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 (its code samples are bash).
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
c4model.com
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
C4 Architecture C4 Architecture loads about 4.1k tokens when it runs. Until then it costs about 39 tokens; SKILL.md has 1,762 words of instructions outside code blocks.
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 1,762 words (~4,115 tokens).
