tmux_show_environment

Read-only

Show a tmux session's environment variables or the global one. Get a specific variable and detect variables marked for removal.

Instructions

Show a session's environment (or the global one with global_=True).

With name, returns just that variable. Variables tmux has marked for removal (shown by tmux as -NAME) are reported as removed=True with a null value.

Returns {"environment": {name: value_or_None}, "removed": [names...]}.

Behavior5/5

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

Annotations indicate readOnlyHint=true. The description adds value by explaining the return format (environment dict and removed list) and how removed variables are reported (removed=True, null value). No contradictions.

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?

The description is concise with a front-loaded main purpose and no superfluous words. The return format is clearly specified, though a bit more structure could help.

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

Completeness3/5

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

The description fully documents the return structure without an output schema, but only partially explains the parameters (session and target are not described). For a read-only tool, the missing param details reduce completeness.

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?

With 0% schema description coverage, the description explains global_ and name parameters but omits details on session and target. This partial coverage adds some meaning but leaves ambiguity.

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?

The description clearly states it shows a session's environment, with options for global and specific variables, and distinct handling of removed variables. This differentiates it from modification tools like tmux_set_environment.

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

Usage Guidelines3/5

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

The description provides context for using the tool (showing environment, global flag) but does not explicitly discuss when to use it over alternatives like tmux_set_environment, or the role of session and target parameters.

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