Run Command

tm_inventory_run_command

Runs shell commands across YAML inventory host groups, or targets one authorized host, with optional preview to confirm the resolved hosts before execution.

Instructions

Run command (tm_inventory). Bulk inventory operations against YAML host groups.

Input Schema

NameRequiredDescriptionDefault
cfgNoLocal SSH config path (copy_ssh_config).
cmdNoShell command (run_command).
keyNoShared key path (configure_key_auth)./app/.ssh/id_ed25519
hostNorun_command only. Optional single-host alias to target instead of the whole 'group' fan-out — the safe way to reach ONE inventory host (e.g. 'gb10') without running against 'homelab'. Resolved and authorized through the same alias store tm_remote/tm_hosts use, so the two are one source of truth: an unknown or unauthorized alias is rejected outright, never silently skipped. Takes precedence over 'group' when set.
groupNoTarget group.all
lpathNoLocal file path (send_file).
rpathNoRemote file path (send_file/receive_file).
key_pfxNoPrefix for new keys (rotate_key)./root/.ssh/id_
previewNorun_command only. If true, resolve the exact target host(s) for 'host'/'group' and return them in 'resolved_hosts' WITHOUT running 'cmd' — lets a caller verify scope before executing for real (no surprise fan-out). The real (non-preview) response also always includes 'resolved_hosts' for the same reason.
rmt_cfgNoRemote config path (copy_ssh_config)./root/.ssh/config
timeoutNoCommand timeout in seconds.
key_typeNoKey type: rsa or ed25519.ed25519
parallelNoRun parallel.
inventoryNoYAML inventory path (default: $XDG_CONFIG_HOME/agent-connectors/inventory.yaml)./root/.config/agent-connectors/inventory.yml
max_threadsNoMax threads.
lpath_prefixNoLocal dir prefix (receive_file).

C2.5/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint=false, openWorldHint=true and non-idempotent, which tells the agent this mutates remote state. The description adds nothing beyond that: no mention of fan-out blast radius, no warning that cmd is arbitrary shell, no reference to preview/scope verification, and no timeout behavior — all of which are the key risks for this tool.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two short sentences with the name restated first, so it is front-loaded and wastes few words. However, the only content sentence ("Bulk inventory operations against YAML host groups") is vague enough that brevity tips into under-specification.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a 16-parameter tool that executes arbitrary shell commands across many hosts, the description says nothing about the single-host vs group targeting model, the preview safety path, or the risk of unintended fan-out. An output schema and rich parameter docs exist, but they don't substitute for a warning about what this tool actually does at scale.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, and the schema itself is unusually rich (host vs group precedence, preview semantics, timeout, parallel/max_threads are all documented inline). The description adds no parameter meaning at all, so the baseline 3 for high coverage applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose3/5

Does the description clearly state what the tool does and how it differs from similar tools?

The verb+resource is present ("Run command"), and "against YAML host groups" hints at the fan-out scope that distinguishes it from tm_remote_run_command. But "Bulk inventory operations" is vague and doesn't say the tool executes a shell command over SSH across a group of hosts, so the agent must infer the actual behavior.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Nothing says when to use this instead of tm_remote_run_command or the other tm_inventory_* siblings. The word "bulk" implies the fan-out case, but there are no explicit conditions, prerequisites, or exclusions given.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
