Codex CLI Subagent Transport

Use this skill only for delegated transport. It does not own routing, phase judgment, acceptance, repair, or specialist semantics.

Load First

• ./references/manifest-based-run-contract.md

Authority Boundary

• This skill owns only the mechanics of one Codex CLI execution.
• The caller owns prompt content, delegated scope, response validation, acceptance, and retry policy.
• This skill must not infer feature state, phase readiness, or acceptance from logs.

Required Inputs

Provide these values explicitly:

• repo root
• feature slug
• assigned phase
• assigned subagent
• prompt file
• model when non-default
• run id when the caller wants deterministic naming
• run root when the caller overrides the default repository-local run location

Required Outputs

Every run must materialize:

• repo-local run directory
• prompt.md
• response.md
• exec.log
• manifest.env
• manifest.json
• printed path assignments for the caller

Invocation

Preferred invocation:

bash ./scripts/run_codex_cli_subagent.sh \
  --repo-root /abs/path/to/repo \
  --feature <feature-slug> \
  --phase <assigned-phase> \
  --subagent <assigned-subagent> \
  --prompt-file /abs/path/to/prompt.md

Stop Rule

• Run exactly one codex exec call.
• Always emit manifest files and printed path assignments after the run finishes.
• Do not retry, reroute, or reinterpret the result inside this skill.
• Treat response.md as the only authoritative payload and exec.log as diagnostics only.
