compose_top

Read-only

View processes running in Docker Compose containers with service-wise ps-style table.

Instructions

Show the running processes of a compose project's containers.

Output is the ps-style process table per service (not JSON); read it from stdout.

args: services - Restrict to these services (default: all) project_dir - Dir with the compose file (default: server cwd) files - Explicit compose file paths (repeatable, -f) project_name - Compose project name override returns: dict - {"returncode": int, "stdout": str, "stderr": str, "truncated": bool}

Behavior4/5

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

Annotations already declare readOnlyHint=true and destructiveHint=false. The description adds useful context: output is ps-style per service, not JSON, and should be read from stdout. It also specifies the return dict structure. 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.

Conciseness5/5

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

The description is concise: it front-loads the purpose and output format in the first sentence, then lists parameters in a clear args block. Every sentence adds value without redundancy.

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

Completeness4/5

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

For a read-only tool with no required parameters and no output schema, the description covers output format, return dict, and parameter details. It could mention error handling or that it wraps `docker compose top`, but current detail is adequate.

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 description coverage is 0%, but the description lists all four parameters with brief but meaningful explanations (defaults, usage hints like `-f`). This compensates for the schema's lack of description, though some parameter details (e.g., file path formats) could be expanded.

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 the tool shows running processes of compose project containers, using a specific verb and resource. It distinguishes from siblings like compose_ps and container_top by specifying the scope (compose project) and output format (ps-style table per service, not JSON).

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 implies usage for displaying process-level information from compose containers, but does not explicitly state when to use this over alternatives like compose_ps or container_top. No exclusions or when-not-to-use guidance is provided.

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