## Findings

No check matched anything in these tool definitions.


## Changes things (3)

Creates or changes something that can be changed back. Claude Code: ask.

### `promptarch_enhance_prompt`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Enhance a raw prompt with PromptArch's Prompt Enhancer: PromptArch asks 1-3 targeted clarifying questions, then rewrites the prompt from the person's answers, optimized for target_model. If this client supports MCP elicitation, the questions appear to the person as a form inside this call. Otherwise call once with just `prompt` to get the questions (free), ask the person, and call again with `questions` and `answers`. Never answer the questions yourself. The enhancement costs 5 credits; questions are free. Requires a PromptArch API key configured as an Authorization: Bearer pk_... header on this MCP server.
```

### `promptarch_generate_artifact`

- The name "promptarch_generate_artifact" says "generate": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Generate an AI agent context artifact (e.g. context_pack, claude_md) from a project description. Requires a PromptArch API key configured as an Authorization: Bearer pk_... header on this MCP server. Consumes credits.
```

### `promptarch_lint_artifact`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Lint an AI agent context file (CLAUDE.md, .claude/rules/ files, AGENTS.md, Cursor rules, Copilot instructions, memory files) with PromptArch's deterministic linter: ~30 research-backed rule families covering current-model anti-patterns (tool-forcing, reasoning-echo, sycophancy triggers, contradictions), per-tool size budgets, secrets/dangerous commands, and hidden-Unicode injection ("Rules File Backdoor"). Returns grade, 0-100 score, and line-anchored findings. Free: no account or credits needed.
```

## Only reads (1)

Looks things up and changes nothing. Claude Code: allow.

### `promptarch_list_artifact_types`

- The name "promptarch_list_artifact_types" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List the artifact types promptarch_generate_artifact can produce from a project description.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `promptarch`:

```json
{
  "permissions": {
    "allow": [
      "mcp__promptarch__promptarch_list_artifact_types"
    ],
    "ask": [
      "mcp__promptarch__promptarch_lint_artifact",
      "mcp__promptarch__promptarch_generate_artifact",
      "mcp__promptarch__promptarch_enhance_prompt"
    ],
    "deny": []
  }
}
```
