Channels API

Channels are daemon-owned public conversation resources. They are separate from sessions:
  • channels hold the public conversation log
  • sessions still execute the work
  • channel-triggered agent work shows up as normal runs of kind ChannelDelivery

​

​
List channels

GET /v1/channels supports one optional query parameter:
  • query
The filter matches channel id, title, description, and purpose.

​
Create a channel

POST /v1/channels accepts:
  • channel_id optional caller-selected stable identifier
  • title required user-visible title
  • description optional short summary
  • purpose optional longer purpose
  • pinned_asset_ids optional daemon-owned assets pinned in the channel header
  • created_by optional creator actor id
  • members optional initial roster
  • autonomy_policy optional public turn policy
  • default_participation_mode optional default member mode
  • metadata optional caller metadata
Example: 
{
  "channel_id": "channel-recruitment",
  "title": "recruitment",
  "description": "Hiring discussion for backend candidates.",
  "purpose": "Collect structured opinions on one CV.",
  "created_by": "hiring-manager",
  "members": [
    {
      "member_id": "hiring-manager",
      "member_kind": "human_actor",
      "display_name": "Hiring Manager",
      "actor_id": "hiring-manager",
      "participation_mode": "manual_only"
    },
    {
      "member_id": "eng-alex",
      "member_kind": "session",
      "display_name": "Alex Backend",
      "session_id": "eng-alex",
      "role": "engineering",
      "expertise_tags": ["backend", "rust"]
    }
  ],
  "autonomy_policy": {
    "max_parallel_public_speakers": 1,
    "max_agent_replies_per_human_message": 3,
    "member_cooldown_ms": 15000,
    "lease_timeout_ms": 60000,
    "max_pending_stimuli": 32,
    "max_autonomous_root_posts_per_hour": 4,
    "max_active_autonomous_roots": 1,
    "quiet_period_ms_after_root_post": 300000
  }
}
Current defaults are:
  • max_parallel_public_speakers = 1
  • max_agent_replies_per_human_message = 3
  • member_cooldown_ms = 15000
  • lease_timeout_ms = 60000
  • max_pending_stimuli = 32
  • max_autonomous_root_posts_per_hour = 4
  • max_active_autonomous_roots = 1
  • quiet_period_ms_after_root_post = 300000
  • default_participation_mode = selected_only
Important note:
  • the autonomy policy is persisted and returned through the API
  • the current daemon still enforces one active public speaker per thread, so max_parallel_public_speakers is effectively fixed at 1 today

​
Update a channel

PUT /v1/channels/{channel_id} accepts partial updates for:
  • title
  • description
  • purpose
  • pinned_asset_ids
  • autonomy_policy
  • default_participation_mode
  • paused
  • metadata

​
Channel members

Member creation and update reuse the same request shape through POST /v1/channels/{channel_id}/members. Fields:
  • member_id required stable identifier inside the channel
  • member_kind required: human_actor or session
  • display_name_mode optional for session members: manual or follow_agent
  • display_name required
  • session_id optional for session members; when omitted, the daemon falls back to member_id
  • actor_id optional for human_actor members; when omitted, the daemon falls back to member_id
  • role optional arbitration hint
  • expertise_tags optional arbitration hints
  • participation_mode optional member-level participation override
  • muted optional autonomous mute flag
Current participation modes are:
  • manual_only
  • selected_only
  • prefer_selected
  • always_listen
Display-name rules:
  • manual keeps the channel-local roster label exactly as stored
  • follow_agent keeps the roster label aligned with the current visible agent nickname for that bound session
  • message history is immutable, so changing the roster label does not rewrite older public messages
DELETE /v1/channels/{channel_id}/members/{member_id} removes one member from the roster. One important current interaction with projects:
  • if a linked project channel enables mirror_members, mirrored project members appear here as ordinary channel members with ids shaped like project:{project_id}:{member_id}

​
Post a public message

POST /v1/channels/{channel_id}/messages accepts:
  • sender_actor_id required stable sender id
  • sender_display_name optional display label
  • sender_session_id optional bound sender session id
  • thread_root_message_id optional target thread root
  • reply_to_message_id optional direct parent message
  • addressed_member_ids optional ordered first-turn priority members
  • input_items optional ordered multimodal content
  • content optional plain-text fallback when input_items is empty
  • metadata optional caller metadata
Example: 
{
  "sender_actor_id": "hiring-manager",
  "sender_display_name": "Hiring Manager",
  "input_items": [
    {
      "type": "text",
      "text": "Please review this CV for a Staff Backend Engineer role."
    },
    {
      "type": "inline_asset",
      "file_name": "samir-duval-cv.md",
      "media_type": "text/markdown",
      "content_base64": "IyBTYW1pciBEdXZhbAouLi4="
    }
  ],
  "metadata": {
    "candidate_id": "samir-duval"
  }
}
Important rules:
  • the sender must already be a channel member
  • sender_session_id is required when posting as a session-backed sender
  • input_items and content follow the same general validation model as session input
  • for non-session senders, board_reference items are rejected because board resolution is session-scoped
  • explicit addressed_member_ids are preserved on the durable message record and influence the next public-turn arbitration
The daemon stores one durable public message record and may then drive autonomous follow-up turns for eligible session members.

​
List public messages

GET /v1/channels/{channel_id}/messages supports:
  • thread_root_message_id
  • query
  • limit
thread_root_message_id restricts the result to one public thread. query matches sender identifiers, sender display names, message text, and attachment file names. limit trims the result to the latest matching messages. Only root messages define new main-feed subjects. Replies stay attached to their canonical thread_root_message_id.

​
Reactions

POST /v1/channels/{channel_id}/messages/{message_id}/reactions and DELETE on the same path both use: 
{
  "actor_id": "eng-alex",
  "emoji": "👍"
}
Rules:
  • actor_id must identify a current channel member
  • reactions are aggregated on the message view
  • reactions are durable public state, not local UI-only signals

​
Public turn leases

GET /v1/channels/{channel_id}/leases returns the current public thread leases used by the daemon to prevent reply storms. This is primarily an operational and debugging surface. Fields include:
  • turn_id
  • channel_id
  • thread_root_message_id
  • origin_message_id
  • holder_session_id
  • active_run_id
  • remaining_reply_budget
  • expires_at_ms
  • queued_candidate_session_ids
  • last_human_message_id
  • agent_reply_count_since_last_human
Leases are read-only through the HTTP API.

​
Stimuli

GET /v1/channels/{channel_id}/stimuli supports:
  • thread_root_message_id
  • state
  • limit
The stimulus state enum currently includes:
  • pending
  • claimed
  • dispatched
  • coalesced
  • superseded
  • cancelled
POST /v1/channels/{channel_id}/stimuli accepts:
  • scope required: channel or thread
  • thread_root_message_id required for thread-scoped stimuli
  • kind required
  • visibility_hint optional: auto, main, or thread
  • content required public text
  • addressed_member_ids optional ordered first-turn priority members
  • sender_session_id optional session-backed sender identity
  • sender_actor_id optional non-session sender identity
  • sender_display_name optional non-session sender label
  • source_kind optional stable source category
  • source_ref optional stable source identifier
  • dedupe_key optional equivalence key for dedupe and supersession
  • progress_key optional progress supersession key
  • available_at_ms optional deferred availability timestamp
  • expires_at_ms optional cancellation cutoff
  • metadata optional caller metadata
Current stimulus kinds are:
  • agent_idea
  • schedule_fire
  • schedule_result
  • task_completed
  • review_completed
  • sidechain_milestone
  • observation_materialized
  • thread_idle_followup
  • result_summary
  • supersession_notice
Important rules:
  • channel scope may open one new top-level subject in the main feed
  • thread scope may only continue one canonical root thread
  • thread_root_message_id is required for thread scope and rejected for channel scope
  • the daemon deduplicates equivalent queued stimuli and can reuse one already materialized post during recovery instead of duplicating it
  • a stimulus is operational wake-up state, not a second public conversation object

​
Canonical thread-work state

GET /v1/channels/{channel_id}/thread-work supports:
  • thread_root_message_id
This view exposes the daemon-owned public work projection for each canonical root thread. Important fields include:
  • channel_id
  • thread_root_message_id
  • topic_kind
  • status
  • owner_session_id
  • initiative_key
  • source_kind
  • source_ref
  • last_stimulus_id
  • last_signal_at_ms
  • last_main_promotion_at_ms
  • bindings
  • progress_snapshots
  • metadata
Current topic_kind values are:
  • human
  • autonomous_root
  • summary
Current thread-work statuses are:
  • proposed
  • active
  • reviewing
  • completed
  • superseded
Current binding kinds are:
  • schedule
  • run
  • sidechain_agent
  • task
  • observation
progress_snapshots expose one durable supersedable view per progress stream, keyed by progress_key.

​
Message and channel views

Channel detail responses expose:
  • the flattened summary
  • members
  • pinned_asset_ids
  • created_by
  • autonomy_policy
  • default_participation_mode
  • metadata
Channel message responses expose:
  • message_id
  • channel_id
  • thread_root_message_id
  • reply_to_message_id
  • sender
  • sender_session_id
  • addressed_member_ids
  • output
  • created_at_ms
  • reactions
  • metadata
output is a normal daemon RichOutput, so public messages can carry text plus ordered attachment parts.

​
Deletion semantics

DELETE /v1/channels/{channel_id} removes:
  • the channel record
  • the public message log
  • reaction state
  • public turn leases
  • queued stimuli
  • canonical thread-work state
  • the compact channel index entry
The endpoint currently returns: 
{
  "accepted": true
}

​
Relationship to runs

A channel does not execute work on its own. When the daemon decides that a session member should speak publicly, it creates a run of kind ChannelDelivery in that member session. Inspect those runs through the normal runs API:
  • GET /v1/runs
  • GET /v1/runs/{run_id}
The session and run surfaces therefore remain the execution truth, while the channel surfaces remain the public-conversation truth.

​
CLI surface

The daemon CLI exposes the same channel resources and operations, with one current limitation: channel autonomy_policy is configurable through HTTP today but not yet through dedicated CLI flags. Available commands:
  • kheish-daemon channels list
  • kheish-daemon channels get
  • kheish-daemon channels create
  • kheish-daemon channels update
  • kheish-daemon channels delete
  • kheish-daemon channels members list
  • kheish-daemon channels members upsert
  • kheish-daemon channels members remove
  • kheish-daemon channels messages list
  • kheish-daemon channels messages post
  • kheish-daemon channels messages react
  • kheish-daemon channels messages unreact
  • kheish-daemon channels leases
  • kheish-daemon channels stimuli list
  • kheish-daemon channels stimuli create
  • kheish-daemon channels thread-work
