Delegate

Delegate

Delegate the next step's execution to Codex live, inside the current Claude session. Produces an approved packet via the shared contract (same helpers /handoff --target=codex uses), then invokes Codex synchronously with codex exec "<target-skill> --execute-approved". Claude stays the orchestrator; Codex executes; Claude resumes once Codex returns.

Unlike /handoff --target=codex (async — user resumes later), /delegate is live cross-CLI transport. The target skill defaults to $exec; other executor skills (e.g. $ship) may be named but $exec is the primary use case.

Mode requirement

/delegate is hybrid-only by design. claude-only has no executor to delegate to; codex-only plans in Codex directly. In either non-hybrid mode, the skill exits non-zero with a mode-mismatch: reason and touches no packet state.

Transport dependency

/delegate requires the codex binary on PATH. If missing (or auth-failed, or the start marker never prints), the skill falls cleanly into the pre-start-failure branch of the fallback matrix — it does not crash, and the packet stays at approved.

Process

1. Resolve agent mode via ./scripts/agent-mode.sh. If the effective mode is anything other than hybrid, exit non-zero with a mode-mismatch: message naming the resolved mode. Do not touch the packet.

2. Parse arguments from $ARGUMENTS:

   • First positional token (if any) is the target skill; defaults to $exec.
   • Collect repeatable --allow-dirty <glob> flags (shell-glob semantics, same as scripts/approved-plan.sh check). Note: back-to-back hybrid cycles rewrite the tasks/approved-plan.md mirror on each consume; commit it between cycles, or pass --allow-dirty tasks/approved-plan.md so the next draft tolerates the uncommitted mirror.
   • --inline-fallback auto-selects inline Claude execution in the pre-start-failure branch without prompting.

3. Derive phase / step / title from tasks/todo.md, using the same rules as /handoff --target=codex:

   • First unchecked - [ ] under the ### Active Step Plan block.
   • Fallback: first unchecked - [ ] under the current ## Phase N header.
   • Parse Phase N and Step N.X tokens from the surrounding context; the checkbox text (stripped of - [ ] **Step N.X** — ) becomes title.

4. Produce the approval packet:

   1. ./scripts/approved-plan.sh draft --phase "Phase N" --step "Step N.X" --title "<title>" plus any --allow-dirty <glob> flags. Surface the helper's single-line failure reason verbatim if it fails.
   2. Pretty-print the drafted packet (jq . .agents/approved-plan.json).
   3. Ask exactly one concise question: "Approve this packet for Codex execution via /delegate?"
   4. On yes → ./scripts/approved-plan.sh approve. On no → leave at draft and stop; the user can approve later or discard with ./scripts/approved-plan.sh supersede.

5. Invoke Codex synchronously:

   • Record a start-marker timestamp (ISO-8601 UTC) before the exec call so the fallback matrix can classify outcomes.
   • Shell out to codex exec "<target-skill> --execute-approved". Capture stdout, stderr, and the exit code.
   • The Step 4 consumer ($exec --execute-approved) is what actually runs scripts/approved-plan.sh check && consume inside Codex. /delegate is transport only.

6. Classify via the safe-fallback matrix — never blind-retry:

   • Pre-start failure — codex binary not found, auth failure, or the start marker was never printed by Codex before exit:

     • Packet stays at approved (no writer ran).
     • Offer two options: (a) run inline in Claude (same session, no CLI boundary), or (b) keep the packet approved for later manual $exec --execute-approved in Codex.
     • If --inline-fallback was passed, auto-select (a) without prompting.
     • Under an agent-team execution profile, inline fallback is a downgrade requiring explicit interactive confirmation unless --inline-fallback is already on the command line.

   • Success — Codex exited 0, printed Approved packet consumed: …, and tasks/approved-plan.md reports lifecycle: consumed:

     • Step 4's consume already flipped approved → consumed.
     • Read tasks/approved-plan.md to confirm lifecycle: consumed. If confirmed, report success and hand back to the user.
     • If the mirror does not report consumed, treat as the ambiguous case below.

   • Ambiguous — non-zero exit, timeout, or crash after the start marker printed (Codex may have started mutating state):

     • Call ./scripts/approved-plan.sh mark-uncertain. The packet lifecycle becomes uncertain.
     • Prompt the user with three explicit options: inspect repo state manually / discard the packet via ./scripts/approved-plan.sh supersede / continue inline in Claude from the current repo state.
     • Never blind-retry codex exec on the same packet. Re-executing against a packet whose consumer may have partially mutated state risks double-execution.

7. Report the classified outcome, the final lifecycle, and whatever the user chose from the fallback prompt.

Constraints

• Hybrid-only. Non-hybrid modes exit with mode-mismatch: before any packet operation.
• Never blind-retry cross-CLI. The invariant. Ambiguous failures always go through mark-uncertain + explicit user prompt.
• Contract is frozen. Do not edit docs/operating-modes.md, specs/approved-plan.schema.json, or add new lifecycle states / freshness checks. uncertain is already in the schema enum; Step 6 is just its first writer.
• mark-uncertain is only valid from approved. The helper rejects draft, consumed, stale, superseded, and uncertain source states.
• codex binary is a transport dependency. Fall cleanly into pre-start-failure if missing; do not crash.
