Available Tools
9 toolsfind_processA
Search for running processes by name using case-insensitive partial matching.
Use this to locate specific processes — for example, find_process("chrome") returns all Chrome-related processes. Use get_top_processes instead when you want to see the highest resource consumers regardless of name. After finding a process, you can use its PID with kill_process to terminate it.
This is a read-only operation with no side effects.
Returns a Markdown table with columns: PID, Name, CPU%, Mem%, RSS, User, Status. Returns a plain text message if no processes match. Processes that exit during enumeration or require elevated access are skipped.
Args: name: Process name or substring to search for. Matching is case-insensitive and partial — "fire" matches "firefox", "Firewall", etc.
| Name | Required | Description | Default |
|---|---|---|---|
| name | Yes |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden. It states 'This is a read-only operation with no side effects.' It also discloses that processes that exit during enumeration or require elevated access are skipped, and describes the return format (Markdown table or plain text).
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is well-structured: front-loaded with the main purpose, then usage, then return format. Every sentence adds value without redundancy. It is concise yet comprehensive.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema, the description explains the return format in detail (Markdown table with columns or plain text for no matches). It mentions edge cases (skipped processes) and provides a complete picture for a search tool with one parameter.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so description must explain the parameter. It thoroughly explains the 'name' parameter: 'Process name or substring to search for. Matching is case-insensitive and partial — "fire" matches "firefox", "Firewall", etc.' This adds significant meaning beyond the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states 'Search for running processes by name using case-insensitive partial matching.' It provides a specific verb (search), resource (running processes), and key characteristics. It also distinguishes itself from sibling tool 'get_top_processes'.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description explicitly says when to use this tool vs. get_top_processes: 'Use get_top_processes instead when you want to see the highest resource consumers regardless of name.' It also explains the workflow: after finding a process, use its PID with kill_process.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
get_battery_statusA
Retrieve battery charge level, power source, and estimated time remaining.
Use this when the user asks about battery life, charging status, or power source. Only available on laptops and devices with a battery. On desktops or VMs without a battery, returns a message indicating no battery was detected.
This is a read-only operation with no side effects.
Returns a Markdown report with: charge percentage, plugged-in status, estimated time remaining (if on battery), and a low-battery warning when charge drops below 20%.
| Name | Required | Description | Default |

Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool retrieves battery charge level, power source, and estimated time remaining using specific verbs and resources. It is distinct from sibling tools like find_process or get_disk_usage, which cover other system aspects.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides explicit usage guidance: 'Use this when the user asks about battery life, charging status, or power source.' It also mentions when not to use (desktops/VMs without battery) and the expected fallback behavior, though it does not explicitly name alternative tools.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
get_disk_usageA
Show detailed disk usage for all mounted partitions with I/O statistics.
Use this for disk space analysis — identifying full partitions, comparing filesystem usage, or checking I/O throughput. For a quick disk summary as part of overall system health, use get_system_overview instead.
This is a read-only operation with no side effects.
Returns a Markdown table with columns: Mount, Device, Total, Used, Free, Usage%, FS type. Also includes cumulative disk I/O since boot (total bytes read/written). Partitions requiring elevated privileges are silently skipped.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
get_top_processesA
List the top resource-consuming processes sorted by CPU or memory usage.
Use this to identify which processes are consuming the most resources. Use sort_by="memory" (default) to find memory hogs, or sort_by="cpu" to find CPU-intensive processes. Use get_system_overview first for the big picture, then this tool to drill down into specific processes. To search for a specific process by name, use find_process instead.
This is a read-only operation with no side effects. When sorting by CPU, takes ~0.5 seconds for accurate sampling; memory sorting is instant.
Returns a Markdown table with columns: PID, Name, CPU%, Mem%, RSS, Status. Processes that exit during enumeration or require elevated access are skipped.
Args: sort_by: Sort criterion — "cpu" for CPU usage or "memory" for RAM usage. Default: "memory". Any value other than "cpu" is treated as "memory". limit: Maximum number of processes to return. Range: 1-50. Default: 10. Values outside the range are clamped automatically.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
kill_processA
Terminate a process by its PID. This is a DESTRUCTIVE operation.
Use this only after identifying the target process with find_process or get_top_processes. Always confirm the PID and process name with the user before calling this tool. Killing system processes may cause instability.
Side effects: sends a signal to the target process.
Default (force=False): sends SIGTERM, allowing the process to clean up gracefully.
force=True: sends SIGKILL, immediately terminating the process without cleanup. May require elevated privileges (sudo) for processes owned by other users.
Returns a confirmation message with the process name, or an error message if the process does not exist or access is denied.
Args: pid: The numeric process ID to terminate. Use find_process or get_top_processes to discover valid PIDs. force: If False (default), send SIGTERM for graceful shutdown. If True, send SIGKILL for immediate termination — use only when SIGTERM fails or the process is unresponsive.
| Name | Required | Description | Default |
|---|---|---|---|
| pid | Yes | ||
| force | No |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, but description fully discloses destructive nature, signal types (SIGTERM vs SIGKILL), permission requirements, side effects, and return types (confirmation or error). Detailed parameter behavior for force.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema has 0% description coverage; description compensates fully by explaining pid (numeric, use discovery tools) and force (default false sends SIGTERM, true sends SIGKILL, when to use each). Adds guidance not present in schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states 'Terminate a process by its PID' with a specific verb and resource. Distinguishes from sibling tools like find_process and get_top_processes by indicating the action is termination, not discovery.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicitly states when to use (after identification via find_process/get_top_processes) and provides critical safety instructions (confirm with user, danger of killing system processes). Mentions alternatives for identification.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
TDQS
Each tool targets a distinct aspect of system monitoring with clear descriptions. Tools like get_system_overview and get_system_health are differentiated by full metrics vs. warnings-only, and process tools (find_process, get_top_processes, kill_process) have non-overlapping purposes.
All tools use a consistent verb_noun pattern: get_ for read-only, find_ for search, kill_ for destructive operations. Naming is predictable and clear, e.g., get_disk_usage, get_network_info, kill_process.
With 9 tools covering CPU, memory, disk, network, ports, battery, and processes, the count is well-scoped for a system monitoring server. No redundancy or missing core functionality.
The tool set provides thorough coverage for system diagnostics: process lifecycle (search, top, kill), resource overviews (system overview, health check), and specific subsystems (disk, network, ports, battery). Gaps like hardware sensors are niche and beyond typical scope.
