At a glance

JunOS system operations via pyATS — chassis health, hardware inventory, system info, NTP, SNMP, files/logs, firewall counters, DDoS protection, services accounting.

  • Works in 3 steps: JunOS Chassis Health Check → JunOS System Audit → JunOS Security Posture
  • Checking Juniper chassis alarms
  • SKILL.md covers Testbed Requirements, How to Call, Commands and Workflows, plus 3 more sections
  • Calls python3; needs NETCLAW_PASSWORD

What it does

Pyats Junos System is an agent skill from automateyournetwork/netclaw. JunOS system operations via pyATS — chassis health, hardware inventory, system info, NTP, SNMP, files/logs, firewall counters, DDoS protection, services accounting. Use when checking Juniper chassis alarms, auditing hardware inventory, reviewing system uptime, or inspecting JunOS firewall counters. For basic cross-platform CPU/memory/interface health checks, pyats-health-check covers Juniper too and is the simpler starting point.

Its SKILL.md is about 3.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Business, Finance & HR, covering Accounting and bookkeeping. The repository describes itself as: An AI agent that claws through your network. The licence is Apache-2.0.

When your agent uses it

  • Checking Juniper chassis alarms
  • Auditing hardware inventory
  • Reviewing system uptime
  • Inspecting JunOS firewall counters

Example prompts

  • “Use the pyats-junos-system skill to juno system operations via pyATS — chassis health, hardware inventory, system info, NTP, SNMP, files/logs…”
  • “/pyats-junos-system”

Requirements

  • Python 3

Workflow steps

3 steps, taken from the step headings in SKILL.md.

  1. JunOS Chassis Health Check
  2. JunOS System Audit
  3. JunOS Security Posture

What it can do on your machine

Read from SKILL.md and the folder at commit aa90e7d. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • python3

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • NETCLAW_PASSWORD

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Pyats Junos System loads about 3.1k tokens when it runs. Until then it costs about 114 tokens; SKILL.md has 662 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~114
When it runs · the whole SKILL.md, loaded when a task matches
~3.1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Workflows

1. JunOS Chassis Health Check
pyats_list_devices → identify JunOS devices
→ show chassis alarms → active alarms (CRITICAL if any)
→ show chassis environment → temperature, fans, power
→ show chassis fpc → FPC online/offline, CPU/memory
→ show chassis routing-engine → RE status, load averages
→ show chassis hardware → hardware inventory baseline
→ Severity-sort → GAIT
2. JunOS System Audit
show version → JunOS version, model, serial
→ show system uptime → device stability
→ show system commit → recent config changes
→ show system storage → disk usage (>80% = WARNING)
→ show system core-dumps → crash history (any = WARNING)
→ show ntp associations → time sync (stratum, offset)
→ Cross-reference version with NVD CVE → vulnerability exposure
→ GAIT
3. JunOS Security Posture
show firewall → active filters
→ show firewall log → recent filter hits
→ show ddos-protection statistics → DDoS protection state
→ show security policies hit-count → policy utilization
→ show snmp statistics → SNMP polling load
→ GAIT

Integration with Other Skills

SkillIntegration
junos-networkJunOS MCP (PyEZ/NETCONF) for config management; pyATS for operational CLI show commands
pyats-junos-interfacesInterface-specific commands complement chassis/system view
pyats-junos-routingRouting protocol commands complement system/hardware view
pyats-health-checkExtend standard health checks to include JunOS chassis metrics
netbox-reconcileCross-reference chassis hardware (serial, model) with NetBox DCIM
nvd-cveScan JunOS versions from show version against NVD
gait-session-trackingEvery command logged in GAIT

Guardrails

  • All commands are read-only — show, file list, and status commands only
  • Always check show chassis alarms first — active alarms take priority
  • Cross-reference with SoT — compare hardware inventory with NetBox/Nautobot
  • Record in GAIT — every command execution must be logged

Failure Behavior

  • If a tool call fails with an authentication or connection error, check that PYATS_MCP_SCRIPT, PYATS_TESTBED_PATH are set and valid before assuming a data or device problem.
  • On a tool error (timeout, unreachable host, malformed response), report the failure and its error message directly to the user rather than fabricating or guessing at results.
  • For a confirmed read-only call, check connectivity and retry once if appropriate. For any call that changes state or sends a message, a timeout does not prove the action failed: inspect current state or delivery status before retrying, preserve the required approval/change gates, and do not repeat an action whose outcome is unknown.
