Sverklo Code Intelligence-061a02 — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited Sverklo Code Intelligence-061a02 (Agent Skill) and scored it 82/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 2 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.

Sverklo is a local-first code intelligence MCP server. It gives you a dependency graph, semantic search, blast-radius analysis, and risk-scored PR review — all running on the user's machine. No API keys, no cloud, no data leaves the laptop.
npm install -g sverklo
cd /path/to/project
sverklo initsverklo init auto-detects the user's AI editor (Claude Code, Cursor, Windsurf, etc.), writes the MCP config, appends sverklo instructions to CLAUDE.md, and verifies the setup. Safe to re-run.
If something looks wrong after setup:
sverklo doctorOnce installed, sverklo tools appear as MCP tools prefixed with sverklo_. The index builds automatically on first use.
Use Sverklo when:
Use Grep when:
FEATURE_FLAG_X exist?")Use Read when:
Skip sverklo for codebases under ~50 source files — the overhead doesn't pay off. Just read everything directly.
Hybrid BM25 + vector + PageRank search. Use instead of Grep when you don't know the exact string.
sverklo_search query:"authentication middleware" top_k:5Returns ranked code chunks with file paths, line numbers, and relevance scores. Results are ordered by structural importance (PageRank), not just text similarity.
When to reach for it: "Where is X handled?", "Find the code that does Y", any exploratory search where you'd otherwise grep for 10 different terms.
Walk the symbol graph and return all transitive callers, ranked by depth.
sverklo_impact symbol:"UserService.validate"Returns every function and file that depends on the symbol, how deep the dependency chain goes, and a risk ranking. Essential before any rename, move, or signature change.
When to reach for it: Before refactoring, renaming, or deleting anything. "What breaks if I change this?"
Analyzes the current git diff and scores each changed file by risk: touched-symbol importance x test coverage x churn history.
sverklo_review_diffReturns files sorted by risk, flags production changes with no corresponding test changes, identifies dangling references, and suggests what to read first.
When to reach for it: Reviewing any PR or diff. "What should I look at first?", "Are there untested changes?"
One-call structural analysis that surfaces god classes, hub files, dead code candidates, and complexity hotspots.
sverklo_auditReturns a health report with specific files and symbols flagged, grouped by issue type.
When to reach for it: Onboarding to a new codebase, planning a refactor, or answering "what's the scariest part of this repo?"
Save decisions, patterns, and invariants pinned to the current git SHA. Recall them later with semantic search and staleness detection.
sverklo_remember content:"We use Postgres advisory locks instead of Redis for cross-worker mutexes — operational familiarity."sverklo_recall query:"rate limiting strategy"Memories survive across sessions. Stale memories (where the referenced code has changed) are flagged automatically.
When to reach for it: Recording architectural decisions, checking what was decided before, any context that should persist across coding sessions.
