Inspect a Linux target

inspect_target

Read-onlyIdempotent

Probe one Linux machine — this host (local) or a remote host over SSH (ssh) — and report its OS, kernel, architecture, package manager, Node/npm, OpenCode, Docker, and per-tool detection flags, plus the names (never values) of credentials present. Read-only: it runs one shell probe as the target user (over SSH when mode:ssh), installs nothing, writes nothing, contacts no external service, and can take a few seconds per hop. Parameter semantics: target.mode selects local vs ssh (default local); target.host is required only for ssh; target.user defaults to the ssh config/current user; target.cwd sets the directory for relative checks; target.port/identityFile pass straight to ssh. Use it to see what a clone would touch, then plan_clone to turn that into an ordered plan and apply_clone to perform it.

Input Schema

Name	Required	Description	Default
`target`	Yes	The machine to operate on: this host (local) or a remote host over SSH (ssh).

Output Schema

Name	Required	Description
`has`	Yes	Detection flags for git, curl, node, npm, corepack, pnpm, docker, uv, gh, opencode, sudo.
`arch`	No	CPU architecture (e.g. x86_64, aarch64).
`home`	Yes	Home directory on the target.
`osId`	No	OS identifier (e.g. ubuntu, debian, rhel).
`user`	Yes	Detected user on the target.
`shell`	No	The target user's login shell.
`kernel`	No	Kernel name and release.
`osName`	No	Human-readable OS name.
`osIdLike`	No	ID_LIKE from /etc/os-release: space-separated distribution family hints.
`configDir`	Yes	OpenCode config directory on the target.
`npmPrefix`	No	npm global prefix, if npm is installed.
`osVersion`	No	OS version string.
`envPresent`	No	Space-separated names of credentials present on the target (values are never read).
`npmModules`	No	npm global modules directory.
`nodeVersion`	No	Installed Node.js version, if any.
`opencodeBin`	No	Path to the opencode binary, if installed.
`skillsCount`	No	Number of SKILL.md files under the target's ~/.config/opencode/skills.
`dockerRunning`	No	Whether the Docker daemon is reachable.
`packageManager`	No	Detected package manager (apt-get, dnf, yum, apk, pacman, zypper, or none).
`opencodeVersion`	No	Version the opencode binary reports, without a leading v (e.g. 2.2.1).
`workspaceDefault`	Yes	Default directory where the profile repo will be cloned.

A4.8/5.0

Behavior5/5

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

Annotations cover readOnly/idempotent/openWorld, yet the description still adds real operational context beyond them: one shell probe as the target user, installs nothing, writes nothing, contacts no external service, and can take a few seconds per hop. It also discloses a privacy-relevant behavior (credential names only, never values) that no annotation conveys.

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

Conciseness4/5

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

Front-loaded with the verb and the report contents, then behavior, then parameters, then sibling routing — a sensible order with no filler prose. It is on the long side and the 'Parameter semantics:' recital partially duplicates the schema, costing a little density.

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

Completeness5/5

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

For a nested-object, single-parameter probe tool with an output schema, everything an agent needs is present: what is inspected, side-effect profile, latency expectation, SSH vs local behavior, and where to go next. Return-value shape is correctly left to the output schema.

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

Parameters4/5

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

Schema coverage is 100%, so baseline is 3, but the description adds meaning the schema does not: mode defaults to local, host is required only for ssh, user falls back to ssh config/current user, cwd governs relative checks, and port/identityFile are raw ssh passthroughs. The only shortfall is that these points largely restate the nested schema rather than adding edge-case behavior (e.g., what happens if host is supplied with mode=local).

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

Purpose5/5

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

Specific verb+resource: 'Probe one Linux machine ... report its OS, kernel, architecture, package manager, Node/npm, OpenCode, Docker, and per-tool detection flags'. It also bounds its own scope (credential names, never values) and positions itself relative to siblings plan_clone/apply_clone, so an agent can separate it from the other inspection-adjacent tools without opening a schema.

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

Usage Guidelines5/5

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

Explicit sequencing guidance: 'Use it to see what a clone would touch, then plan_clone to turn that into an ordered plan and apply_clone to perform it.' It names the downstream alternatives and the condition under which they are used, plus the mode-selection rule (local vs ssh, default local).

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