batfish-config-analysis

batfish-config-analysis is a skill for Claude Code from automateyournetwork/netclaw. It costs 60 tokens per session (1,341 once invoked), scanned A, original, Apache-2.0.

A network-configuration checker that uses Batfish, a tool for testing how device configurations would handle network traffic before deployment.

In plain words
What is it for?
Use it to upload configurations, validate devices, test reachability, trace traffic through access-control rules, compare snapshots, and check compliance policies.
Why use it?
It can reveal invalid settings, blocked or unintended traffic paths, and differences between configuration versions before changes reach real devices.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

batfish-config-analysis scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Batfish Configuration Analysis

MCP Server

  • Source: Built-in (mcp-servers/batfish-mcp/)
  • Command: python3 -u mcp-servers/batfish-mcp/batfish_mcp_server.py (stdio transport)
  • Requires: Batfish Docker container running, BATFISH_HOST and BATFISH_PORT environment variables
  • Python: 3.10+
  • Dependencies: pybatfish, mcp[cli], python-dotenv

Available Tools (8)

Tool Parameters What It Does
batfish_upload_snapshot snapshot_name, configs/config_path, network Upload device configs to Batfish and create a named snapshot
batfish_validate_config snapshot_name, network Validate configs with per-device pass/fail status, vendor detection, warnings
batfish_test_reachability snapshot_name, src_ip, dst_ip, protocol, dst_port Test if traffic can flow between two endpoints with full path trace
batfish_trace_acl snapshot_name, device, filter_name, src_ip, dst_ip, protocol, dst_port Trace a packet through ACL rules to find matching permit/deny rule
batfish_diff_configs reference_snapshot, candidate_snapshot, include_routes, include_reachability Compare two snapshots for route and reachability differences
batfish_check_compliance snapshot_name, policy_type Check configs against compliance policies (6 built-in policy types)
batfish_list_snapshots network List all available snapshots
batfish_delete_snapshot snapshot_name, network Delete a snapshot

Workflow: Pre-Change Validation

When a user wants to validate configurations before deployment:

  1. Upload configs: batfish_upload_snapshot with inline configs dict or path to config directory
  2. Validate: batfish_validate_config to check parse status, vendor detection, warnings/errors
  3. Test reachability: batfish_test_reachability for critical traffic paths
  4. Check compliance: batfish_check_compliance against organizational policies
  5. Report: Structured pass/fail results with specific findings
  6. GAIT: All operations automatically logged

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
