agent-models

Each Claude subagent's model and effort in Claude Code's agent list.

Claude Code's agent list shows a subagent's task but not what it runs on. With this mod each row carries it, the way the codex mod's rows do:

Review auth · Opus 5.5 (high)
Check label.ts · Sonnet 5.5 (medium)
Say ok · Haiku

| The agent | Its label | | --------------------------------------------------- | ------------------------------------------------- | | general-purpose, a fork, an agent file's inherit | the parent's model and effort | | an agent file with model: (and effort:) | that model, and that effort | | the Agent tool's model option | that model; the parent's effort only if the same model | | Explore, Plan and other built-ins | none: their model is the engine's to choose | | a plugin's agent (codex:read) | none: the plugin labels its own |

Where the model cannot be known before the agent starts, the row is left as it was rather than guessed.

Requirements

• Claude Code with mods (tested on 2.1.287)

Install

/plugin marketplace add alex2481kobe/claude-mods
/plugin install agent-models@claude-mods

How it works

• An agent.spawn hook, which runs before the subagent starts, appends · <model> (<effort>) to the task's description; the agent list shows that description.
• The model is the Agent tool's model option, else the agent file's, else the parent's for the agents that inherit it. Agent files are read from the project's .claude/agents/ and your own (~/.claude/agents/, or $CLAUDE_CONFIG_DIR/agents/), matched by their name.
• The effort is the agent file's effort, else the effort of the parent's latest request, and that only when the agent runs on the parent's own model: another model may take no effort at all (Haiku takes none).
• Model ids read as people say them: claude-opus-5-5 is Opus 5.5.

Limits

• An agent file in a subfolder of agents/, or one defined in settings, a flag or policy, is not read, so its agent goes unlabelled.
• An agent file with no model: line is left unlabelled.
• An alias reads as its name without a version: haiku is Haiku.
• An agent file's effort is shown even when the Agent tool's model option overrides its model.
• Tried in the interactive terminal and headless (claude -p).
• The mods API is early access and may change between Claude Code releases.
