call-claude

Delegate an arbitrary prompt to Claude and return the output.

Arguments

Required: a prompt.

Optional flags (parsed from the user's message):

Flag	Values	Default
--model	opus, sonnet, haiku, or a full model ID	opus
--effort	low, medium, high, xhigh, max	(omitted)

Process

1. Parse the user's message — extract the prompt and any --model / --effort overrides.
2. Invoke the wrapper script that ships alongside this SKILL.md:

   "$(dirname "$0")/call-claude.sh" [--model <alias>] [--effort <level>] "<prompt>"
   

   For multi-line prompts, pipe via stdin:

   echo "<prompt>" | "$(dirname "$0")/call-claude.sh" --model opus
   

3. Return Claude's full output to the user. Don't summarize unless asked.

claude -p is non-interactive and prints the final answer to stdout, so the wrapper output can be captured directly.

Prerequisite

Claude Code must be installed — verify with claude --version.

Examples

# Default (opus)
./call-claude.sh "explain what this repo does"

# Override model
./call-claude.sh --model sonnet "summarize the README"

# Override model + effort
./call-claude.sh --model opus --effort high "design a caching layer"
