Claude Runner

Claude Runner

Execute the caller's scoped prompt through the local CLI. Shared roles, envelope keys, and result handling live in shared/references/runner-common.md. Preserve seat fidelity: name the provider that actually answered, and report unavailable or unverified seats honestly.

Native routing

Read shared/references/host-model-execution.md before choosing an external route. If the current host can dispatch the exact selected Claude model with the required effort, isolation, and receipt policy in a native subagent or task thread, use that route. agents/openai.yaml is host UI metadata; it does not dispatch a native model.

Invocation

Set SKILL_DIR to this loaded skill directory in the same shell call:

SKILL_DIR="<absolute path of this skill directory>";
python3 "$SKILL_DIR/scripts/run_claude.py" "<scoped prompt>" --json

An approved workflow supplies the exact model, effort, role, tool mode, and receipt policy. Pass those approved options and --disable-fallback; this basic example does not authorize a different route.

Runtime boundaries

• Use the local authenticated claude CLI in print mode. Permission checks remain enabled.
• Analysis roles default to read-only planning mode. --restrict-tools forces it; --allow-write opts out within the caller's authority.
• Prompt and file context may be sent to the configured provider. Bare mode changes authentication behavior; read the runtime reference before using it.
• The wrapper forwards model and effort. Current print output does not prove the serving model; a configured label alone gives an unverified receipt.
• Direct calls can fall back once to codex-runner when the CLI is missing. Approved routes disable fallback; native session continuation must preserve the selected runner.

Load by need

• references/command-reference.md: flags, examples, native mappings, and return codes when composing a non-basic invocation.
• references/runtime-reference.md: authentication, fallback conditions, configuration, and extended envelope fields when configuring a route or interpreting its result.
• references/continuation.md: only when resuming a session or managing a background job.

Result

Read agent_message and the wrapper envelope. Check success, serving-model receipt, effective runner/provider, and any fallback or malformed-output status. A completed process alone does not prove the requested task or model was used. Report touched files when the caller authorized edits.
