Ccb Self Diagnose

CCB Self Diagnose

Use this skill for read-only triage. Prefer CCB control-plane diagnostics and read-only tmux evidence. Do not mutate runtime state from this skill.

Evidence Model

Keep these categories separate in every diagnosis:

• Authority: current mounted daemon service graph, lifecycle, lease, current configured-agent runtime records, loaded config, and separately the current server-wide Mobile host generation when Mobile/Relay is in scope.
• Evidence: ccb ping, ccb doctor, ccb ps, ccb queue, ccb pend, ccb trace, ccb fault list, ccb doctor logs <agent>, reply/artifact records, tmux pane metadata/text capture, provider session files, pid files, and config validation or reload dry-run output.
• Residue: disk-only .ccb/agents/* directories for unknown agents, stale panes, stale sockets, old session artifacts, dead helpers, and orphaned provider state.

Configured-agent and restart target authority comes from the mounted daemon graph, not disk config, tmux panes, or .ccb/agents/* residue.

Core Workflow

1. Confirm the project anchor and current mounted daemon generation.
2. Gather the control-plane snapshot:
   • ccb ping ccbd
   • ccb doctor
   • ccb ps
   • ccb queue --detail all
   • ccb fault list
   • ccb pend --inbox --detail <agent> when one agent is suspected
   • ccb trace <job_id|message_id|attempt_id|reply_id> for lineage issues
   • ccb doctor logs <agent> when provider/API evidence is needed
3. Gather read-only tmux evidence when pane or provider state matters:
   • current CCB tmux namespace/session/socket
   • pane ids, active/dead flags, titles, current commands, and captured text
   • activity sampling when supported
   • provider session and pid-file paths plus modification times when useful, without reading secret or private provider-state contents
4. For config drift, run ccb config validate first, then ccb reload --dry-run. Do not treat disk config as live graph until reload has succeeded and the daemon graph has been rechecked.
5. For artifact-backed replies or requests, read the full artifact file before acting. If the full file is absent or expired, report a blocker and do not infer from preview text alone.
6. Classify the failure domain and hand off:
   • daemon lifecycle, namespace, pane, provider context, config drift, or storage boundary -> ccb-self-recover
   • job/message/reply/artifact/chain lineage -> ccb-self-chain
   • config design/edit/reload readiness -> built-in ccb-config
   • Mobile host, route, pairing/device, Relay, or capability negotiation -> ccb-mobile-relay-maintain

Failure Domains

Use the smallest domain that explains the evidence:

• Daemon lifecycle: no mounted daemon, unhealthy heartbeat, bad lease, stale generation, socket issue.
• Tmux namespace/pane: missing CCB namespace, dead pane, stale pane id, pane text not changing, layout/sidebar mismatch.
• Provider context/API: auth, quota/rate limit, model mismatch, endpoint/base URL, network, provider outage, or corrupted conversation context. Do not read secrets.
• Message chain: queued ask, missing reply, incomplete reply, pending chain, artifact-backed reply not read, or retry/resubmit/ack decision.
• Config drift: disk config differs from loaded daemon graph, dry-run reload blocked, role binding missing, or changed startup inputs need post-reload runtime refresh.
• Storage boundary: provider state or runtime files live in the wrong root, or project/runtime relocation rules are violated.
• Mobile/Relay: server-wide host unhealthy, endpoint not CCB-owned, pairing expired, device unauthorized, project discovery stale, route unavailable, or Provider controls absent because host capability is too old.

Red Lines

• Do not run ccb reload, ccb clear, ccb repair, ccb restart, ccb kill, or raw tmux mutation from this skill.
• Do not read provider auth, credentials, API keys, or unrelated private provider state.
• Do not use screenshots unless pane text/metadata is insufficient and the target is CCB-owned.
• Do not present tmux evidence as configured-agent authority.
