setup-serena-mcp — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited setup-serena-mcp (Agent Skill) and scored it 91/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

Check whether you have access to Serena MCP server by attempting to use one of its tools (e.g., find_symbol or get_symbols_overview).
If no access, proceed with setup.
Read the following documentation to understand Serena's capabilities and setup process:
Based on the loaded documentation:
uv is installed (required for running Serena)After adding MCP server, but before testings connection write to user this message EXACTLY:
You must restart Claude Code to load the new MCP server:
1. Exit Claude Code console (type exit or press Ctrl+C)
2. Run claude --continue
3. Type "continue" to resume setup
After restart, I will:
- Verify Serena tools are accessible
- Run initial_instructions if needed
- Perform onboarding for this project (if not already done)
Use the path determined in step 1. Once Serena is successfully set up, update the appropriate CLAUDE.md file with the following content EXACTLY:
### Use Serena MCP for Semantic Code Analysis instead of regular code search and editing
Serena MCP is available for advanced code retrieval and editing capabilities.
**When to use Serena:**
- Symbol-based code navigation (find definitions, references, implementations)
- Precise code manipulation in structured codebases
- Prefer symbol-based operations over file-based grep/sed when available
**Key tools:**
- `find_symbol` - Find symbol by name across the codebase
- `find_referencing_symbols` - Find all symbols that reference a given symbol
- `get_symbols_overview` - Get overview of top-level symbols in a file
- `read_file` - Read file content within the project directory
**Usage notes:**
- Memory files can be manually reviewed/edited in `.serena/memories/`
Add this section, if server setup at user level (global):
**Project setup (per project):**
1. Run `serena project create --index` in your project directory
2. Serena auto-detects language; creates `.serena/project.yml`
3. First use triggers onboarding and creates memory files in `.serena/memories/`If this is a new project or Serena hasn't been initialized:
~30 seconds. Free. No account. Every finding cites a rule and a line of evidence.
