CCB Agent Delegate

Use this when the user asks you to delegate with CCB, or when project memory says to use CCB ask for collaboration.

Decision Card

Before every ask, decide:

1. Need delegation? If no, answer directly.
2. Result intent:
   • --silence: publish/execute task; success result not needed. Failures, blockers, risks, or required next actions still surface.
   • --compact: result wanted, but only distilled findings/status/risks/blockers/next actions.
   • + --artifact-reply: consultation/analysis/report where full text should be preserved.
   • plain ask: short question or short handoff where inline text is enough.
   • --callback: active CCB parent job + child result required to finish. Combine with --compact or --artifact-reply as needed. Submit, then stop for continuation.
3. Request fidelity:
   • + --artifact-request: exact transient input (logs/output/diffs/copied contents/config/JSON/YAML/table/structured text). Prefer repo paths when the target can read files directly.
   • --artifact-io: request and reply both need artifacts.

Guardrails

• Do not probe --callback; if unsure there is an active parent job, use plain ask.
• If CCB says ask --callback requires an active parent job, retry once with plain ask for user-requested delegation.
• --callback and --silence usually conflict; avoid mixing unless explicit.
• Avoid --silence --artifact-reply; silence means no caller result needed; artifact-reply preserves one.
• Artifact flags are orthogonal to --callback, --silence, and --compact. They preserve content, not dependency shape.
• Automatic spill for text over 4 KiB is a fallback, not the primary rule.
• --artifact-* modes are CCB/daemon managed; targets do not write artifact reply files.
• Plain nested ask from an active CCB task is rejected; use --callback or --silence.
• In A --silence -> B, B still runs an active job. B-to-C depends on whether B needs C's result.
• In callback chains, each waiting hop uses callback; CCB then propagates continuations.
• ask get, pend, watch, and ping are diagnostics-only commands for explicit debugging requests, not normal ask workflow tools.
• Do not manually append output-policy text; ask injects reply guidance.

Always send MESSAGE through the <<'EOF' ... EOF heredoc below. No other form is allowed. Use no flags or insert selected flags before "$TARGET":

command ask "$TARGET" <<'EOF'
$MESSAGE
EOF

command ask --callback --artifact-reply "$TARGET" <<'EOF'
$MESSAGE
EOF

After the command returns, end the turn. Do not wait for a reply, do not run ask get / pend / ping / watch, do not poll. For --callback, report only that delegation was submitted.
