Coordination: Read Receipts & Locks

Deterministic CLI commands over the same store as the MCP read_receipts / lock tools, for shell loops and CI checks.

conversations receipts 123                          # who has read message 123
conversations receipts 123 --channel engineering    # ...and which members have not
conversations locks acquire deploy --ttl 300 --from riley   # exit 0 acquired, 2 held elsewhere
conversations locks check deploy                    # exit 0 free, 2 locked
conversations locks release deploy --from riley
conversations locks list --json
conversations locks clean                           # drop expired/stale-agent locks

Locks share the MCP lock store: the key is the lock's resource_id, and --type selects the resource namespace (default resource). Acquiring a key you already hold refreshes its TTL; a conflict DMs the holding agent unless --no-dm is passed.

Channels can carry a class for fleet taxonomies at metadata.channel_schema.class via channel create <name> --class <class> and channel update <name> --class <class> (empty value clears it).

Compact Output Defaults

Agent-facing commands are compact by default so busy stores do not flood the terminal or model context. List/read/search commands show bounded rows, message ids, previews, and a hint for the next detail step.

conversations read --to codex              # compact previews
conversations read --to codex --verbose    # full message bodies
conversations show 123                     # one full message
conversations read --to codex --json       # full machine-readable records
conversations read --to codex --limit 10 --cursor 10
conversations digest engineering --cursor 123 --max-bytes 8192 --json

The same gradual disclosure pattern applies to channel reads, message search, recent activity, pinned messages, blockers, channel/project/agent/session lists, and watch output. Use --json when a script needs the stable full record shape; use terminal defaults for agent-safe scanning.

For long-running loops and autonomous agents, conversations digest <channel> returns a stable compact evidence packet instead of replaying the full channel. The JSON output includes digest_id, message_ids, next_cursor, bounded snippets, and byte_length; pass next_cursor back as --cursor to continue. Digests are non-destructive by default. Use --unread to restrict the digest to unread messages and --mark-read --from <agent> only when consuming the returned messages should update read state.

Channel names are normalized to stable human-readable ids. For example, #Engineering Updates is stored as engineering-updates.

The conversations-hook binary is still installed for hook integrations:

conversations-hook --help

Shared Event Webhooks

conversations exposes the shared @hasna/events commands so local events can trigger deterministic or agentic automation without custom glue scripts. To route conversation events into an OpenLoops worker/verifier template, register a command webhook:

conversations webhooks add loops \
  --id openloops-conversations-events \
  --transport command \
  --source conversations \
  --type "*" \
  --arg=events \
  --arg=handle \
  --arg=generic \
  --arg=--provider \
  --arg=codewith \
  --arg=--auth-profile \
  --arg=account005 \
  --arg=--permission-mode \
  --arg=bypass \
  --arg=--sandbox \
  --arg=danger-full-access \
  --timeout-ms 900000 \
  --json

@hasna/events sends the event envelope on stdin and in HASNA_EVENT_JSON. OpenLoops can then create a deduped one-shot workflow for the event. Keep the event payload scoped and include working_dir, project_path, or repo_path when a downstream agent needs to run inside a specific repository.

MCP Server

conversations-mcp

MCP exposes channel-first tools such as create_channel, list_channels, send_to_channel, read_channel, join_channel, leave_channel, subscribe_channel_notifications, and summarize_channel.

MCP read/list/search tools also default to compact summaries. Pass verbose: true to read_messages, read_channel, search_messages, list_tasks, search_tasks, get_comments, get_task_tree, and related list tools when full raw records are needed. Detail tools such as get_message, get_task, and get_project return full records for a single id. Use read_digest with channel, cursor, and max_bytes for byte-capped channel evidence packets that return snippets plus digest_id, message_ids, and next_cursor.

HTTP mode

Long-lived Streamable HTTP transport (stateless, bind 127.0.0.1 only):

conversations-mcp --http              # default port 8856
conversations-mcp --http --port 8856
MCP_HTTP=1 conversations-mcp

• Health: GET http://127.0.0.1:8856/health
• MCP: http://127.0.0.1:8856/mcp

The dashboard server also exposes /health and /mcp when running.

Self-hosted HTTP API (conversations-serve)

conversations-serve is the self_hosted service surface. It is pure remote (Amendment A1): every read and write goes straight to the app's cloud Postgres via the vendored @hasna/contracts storage kit — no SQLite, no cache, no sync engine in the process. Requests to /v1/* are authenticated with @hasna/contracts API keys (scope grammar conversations:read / conversations:write).

export HASNA_CONVERSATIONS_STORAGE_MODE=cloud
export HASNA_CONVERSATIONS_DATABASE_URL="postgres://…?sslmode=require&uselibpqcompat=true"
export HASNA_CONVERSATIONS_API_SIGNING_KEY="$(openssl rand -hex 32)"
conversations-serve                     # listens on :8080 (PORT/HOST configurable)

# one-shot schema migration (owner role, idempotent)
HASNA_CONVERSATIONS_DATABASE_URL_OWNER="postgres://…" bun run src/server/migrate.ts

Endpoints:

• GET /health · GET /ready · GET /version → {status, version, mode} (unauthenticated probes)
• GET /v1/openapi.json → the OpenAPI document the SDK is generated from
• /v1/messages, /v1/channels, /v1/projects, /v1/agents → versioned CRUD (API-key auth)

Issue a key with the contracts CLI:

contracts issue-key --app conversations --agent my-agent \
  --scopes "conversations:read,conversations:write"

Typed SDK client

The SDK is generated from the serve OpenAPI (bun run sdk:generate) and shipped under the @hasna/conversations/sdk export:

import { ConversationsClient } from "@hasna/conversations/sdk";
const client = new ConversationsClient({
  baseUrl: process.env.CONVERSATIONS_API_URL!,
  apiKey: process.env.CONVERSATIONS_API_KEY!,
});
await client.sendMessage({ from: "me", to: "you", content: "hi", channel: "deploys" });

Channels

Conversations uses flat channels. There is no runtime hierarchy and no space/sub-space public compatibility surface. Direct messages, channel messages, threads/replies, participants, unread state, mentions, tasks, projects, webhooks, graph links, and storage sync metadata all reference the canonical channel id.

Rename a channel while keeping all of its messages, members, subscriptions, and history intact:

conversations channel rename old-name new-name
conversations channel update old-name --name new-name   # equivalent

Renames are rejected if the target name already exists or the source channel is not found. The same capability is exposed over MCP via rename_channel and the new_name field on update_channel.

Upgrading from older releases runs a one-time migration from spaces to channels. Every legacy space and sub-space becomes one flat channel. Parent context is preserved in channel metadata and tags, not as a nested channel tree. Legacy message-only references are imported as channels too, and naming collisions are resolved deterministically with suffixes.

Storage Sync

This package supports optional remote storage sync to a PostgreSQL database:

export HASNA_CONVERSATIONS_DATABASE_URL="<value from hasna/xyz/opensource/conversations/prod/rds>"
conversations storage status
conversations storage push
conversations storage pull

Production storage for Hasna XYZ uses the conversations database on hasna-xyz-infra-apps-prod-postgres. The runtime secret path is hasna/xyz/opensource/conversations/prod/rds; load that secret into HASNA_CONVERSATIONS_DATABASE_URL for runtime or smoke commands and do not print the value. CONVERSATIONS_DATABASE_URL remains available as a local/self-hosted fallback.

Before cutover, verify conversations storage status, run a read-only smoke against the canonical database, and keep legacy sources read-only until the central rollback window closes.

By default, sync only includes text-key/global tables to avoid local integer ID collisions across machines.
