Architecture

What it does

When your agent uses it

• Asks to map the architecture
• Show module dependencies
• Analyze coupling
• Dependency graph

Example prompts

• “map the architecture”
• “show module dependencies”
• “analyze coupling”
• “/architecture”

Requirements

• Compatibility (from SKILL.md): Requires grepika MCP server.
• Pre-approved tools (allowed-tools): mcp__grepika__search, mcp__grepika__refs, mcp__grepika__outline, mcp__grepika__toc, mcp__grepika__get, mcp__grepika__graph, mcp__grepika__structural_search, mcp__grepika__add_workspace

Workflow steps

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

1. 1Map module boundaries
2. 2Trace inter-module dependencies
3. 3Identify coupling hotspots
4. 4Trace data flow
5. 5Assess module cohesion

What it can do on your machine

Read from SKILL.md and the folder at commit f035a18. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves these tools, so the agent can use them without asking each time:

  • mcp__grepika__search
  • mcp__grepika__refs
  • mcp__grepika__outline
  • mcp__grepika__toc
  • mcp__grepika__get
  • mcp__grepika__graph
  • mcp__grepika__structural_search
  • mcp__grepika__add_workspace

  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.

• Compatibility

  Requires grepika MCP server.

  From compatibility in the SKILL.md frontmatter.

Context cost

Architecture loads about 1.1k tokens when it runs. Until then it costs about 70 tokens; SKILL.md has 307 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~70

When it runs · the whole SKILL.md, loaded when a task matches

~1.1k

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

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.

## Architecture Analysis: [focus area or "Full Codebase"]

### Module Map

| Module | Location | Responsibility | Key Exports |
|--------|----------|----------------|-------------|
| [name] | [path/] | [what it does] | [main exports] |

### Dependency Graph

### Coupling Analysis

| Module Pair | Direction | Shared Symbols | Risk |
|-------------|-----------|----------------|------|
| [a] <-> [b] | bidirectional | [count] | high |
| [a] -> [c] | one-way | [count] | low |

### Data Flow

### Hotspots

- **Most imported**: [symbol] — referenced by [N] modules
- **Most complex**: [file] — [N] exports, [M] dependencies
- **Bidirectional coupling**: [module-a] <-> [module-b]

### Architectural Observations

- **Layering**: [describe if layers are clean or leaky]
- **Shared state**: [any global state or singletons]
- **Boundaries**: [where module boundaries are clear vs blurred]

### Recommendations

- [actionable suggestions for improving architecture]
