Duoduo Channel Admin

Host-mode channel lifecycle and channel-facing configuration. Route by kind (Feishu / WeChat / ACP) and by task (install / configure / diagnose / reset).

Start with discovery

Before making any change, run the smallest read-only probe:

duoduo daemon status             # confirm host mode, daemon alive
duoduo daemon config             # resolve kernel_dir, runtime_dir, defaults
duoduo channel list              # see installed plugins + running state

When editing a specific channel instance, always inspect the current descriptor first:

cat <runtime_dir>/var/channels/<channel_id>/descriptor.md

Route by kind

Each channel kind has its own reference. Load only the one that matches the request to avoid polluting context with unrelated detail.

• Feishu (飞书) → read references/feishu.md. Covers install, credentials, v0.5 /setup routing matrix, main session contract (owner DM auto-spawn), FEISHU_BOT_OWNER security hygiene, 200340 triage, reset walkthrough, stale-card guard, accepted v0.5 limits.
• WeChat (微信) → read references/wechat.md. Covers install, start, QR login, state-dir resolution.
• ACP (编辑器) → read references/acp.md. Covers install, editor integration semantics.

When the request is "diagnose a misbehaving Feishu channel" and the symptom isn't obvious, read references/diagnose-feishu.md — it walks a decision tree (card errors, /setup refusals, stale history, stranger access, ownership drift) to the right remediation.

Configure channel behavior

Descriptor model: kind-level for defaults applied to every channel of a kind; instance-level for one specific channel.

• Kind descriptor: <kernel_dir>/config/<kind>.md
• Instance descriptor: <runtime_dir>/var/channels/<channel_id>/descriptor.md

Editable keys by hand:

• new_session_workspace
• prompt_mode
• time_gap_minutes
• stream
• allowedTools
• disallowedTools
• additionalDirectories

v0.5 adds three keys normally written by channel.spawn (not hand- edited): runtime, bound_by, bound_at. See references/channel-config-model.md for the full list and the new_session_workspace priority rules.

For frontmatter edits that must preserve Markdown body and comments, use scripts/patch_markdown_frontmatter.py.

Reset a bound channel

When a channel's descriptor, session, or message history is stale and the user wants a clean slate:

bash scripts/reset-feishu-session.sh --channel-id feishu-<chat_id>
duoduo channel feishu stop && duoduo channel feishu start

The script calls duoduo session archive <session_key> for every session that references the channel. That RPC moves the session dir + ingress + outbox records + channel descriptor under var/<kind>-archive/ (timestamped, reversible via mv). The plugin restart is mandatory — it caches subscription state in memory.

Read references/reset-feishu-session.md for what the script cleans and why each piece matters. When users report "bot quotes old messages after I reset", they hit the reason this script exists.

Prompt editing

• The Markdown body of kernel/config/<kind>.md is the kind prompt.
• The Markdown body of descriptor.md is the instance prompt.
• Instance frontmatter and prompt override kind defaults.
• Preserve bootstrap-seeded guidance comments when possible.

Operating rules

• Prefer the smallest scope: kind-level for defaults, instance-level for a single room or session surface.
• After editing ~/.config/duoduo/.env channel credentials, restart the affected channel process (not just the daemon).
• After installing a new plugin, verify with duoduo channel list and duoduo channel <type> status.
• If a channel fails after credentials, install state, and runtime config all look correct, treat it as a likely product or plugin issue — see ../duoduo-admin/references/issue-reporting.md.
• If the request is really about telemetry, cadence, debug logs, or Codex, hand off to duoduo-runtime-admin.
