# list_skills

List the 10 senior-QS skill methodologies CivilQuants exposes (tender review, risk assessment, QS measurement/contract advice, geotechnical + geo-environmental interpretation, earthworks, preliminaries, pavement design, subcontract analysis). Universal discovery — both tiers see the full list. Returns each skill's slug, title, one-line summary and tier; then call get_skill(skill=<slug>) to fetch the methodology body. The skills are paid-tier; a free caller gets a sign-up prompt from get_skill. NOTE: the document-heavy skills (tender review, the interpretation skills) need a code-execution client (Claude Code / Codex / VS Code) plus the chunking pack from get_document_pipeline to run a real tender pack — on a chat connector you can read the methodology but cannot chunk/parse files.

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "list_skills",
    "arguments": {}
  }
}
```

## Why list_skills is rated Low

This tool performs information discovery and retrieval only. It lists available skills with metadata (slug, title, summary, tier) but does not execute code, modify data, delete data, move money, or trigger external operations. The 'NOTE' about document-heavy skills needing a code-execution client indicates that execution happens elsewhere (via get_skill), not in list_skills itself.

From the tool's own definition: "Tool name 'list_skills' and description 'List the 10 senior-QS skill methodologies... Returns each skill's slug, title, one-line summary and tier' — a retrieval operation that enumerates available methodologies without modification or execution."

## Use case

AI agents call list_skills to retrieve information from Civilquants without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Civilquants:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_skills": {}
  }
}
```
