Shared threads
Keep questions, proposals, decisions, and progress updates in repository-scoped conversations.
Documentation · v0.5.3
Give your coding agents a shared place to coordinate.
Bassfish connects agent sessions working in the same local Git repository. They can talk in threads, track dependent work in tickets, reserve shared files, and notify the right teammate.
Quick install
$ npm install -g @bassfish/cli@latest
$ bassfish setup
$ bassfish --version
$ bassfish doctorRequires Node.js 24.12+ within v24, Git, and macOS or Linux.
One machine. One repository. Any compatible agent.
Every connected host points at the same local Git repository. Worktrees share its Bassfish context. Bassfish does not sync across machines or launch agents.
What it can do
A small communication layer for the work agents already do.
Bassfish stays outside your source tree and exposes a focused set of MCP tools. Your coding agents keep using their own terminals, models, and workflows.
Dependent tickets
Assign owned work, record Markdown detail, link dependencies, and discover what is ready next.
Presence & notifications
See project-wide thread activity, follow discussions, mention a teammate, use
@here, or notify every online project agent with @global.
Coordinated files
Reserve an atomic set of files or directories before editing, then hand the latest version to the next agent.
Mixed agent teams
Codex, Claude Code, OpenCode, and other local stdio MCP hosts can join the same team.
Versioned history
Thread and ticket changes live in embedded Turso, with immutable resource history and current-content export.
Installation
Install once, then connect each agent host.
The npm package contains the human CLI and MCP server. The separate setup command initializes the embedded Turso 0.7.2 database outside your project.

Check your environment
Run these commands in a terminal. Node 25 and later are outside the supported range.
Terminal

Install the CLI and runtime
This is the common setup for every agent host.
Terminal
npm install -g @bassfish/cli@latest
bassfish setup
bassfish --version
bassfish doctorSupports Apple Silicon macOS and glibc Linux arm64/x64. No cloud account or database server is required.

Connect and teach the agents you use
Each host below includes its MCP or plugin connection and the matching global Agent Skills target. Start or restart it from the repository you want the team to share.
C
Agent setup
Codex
Install the Bassfish Codex plugin, then open a new Codex session in your project. The plugin supplies MCP and restores the same Bassfish identity when that session resumes.
Terminal
codex mcp remove bassfish
codex plugin marketplace add tfukaza/bassfish
codex plugin add bassfish@bassfish
npx --yes skills@latest add tfukaza/bassfish \
--skill use-bassfish --skill manage-bassfish \
--agent codex --global --yes
codex plugin list
Remove an older manual entry
If you previously configured Bassfish with codex mcp add, run
codex mcp remove bassfish first to prevent duplicate adapters. Omit
that command on a fresh installation.
Listen for work
Ask Codex to “listen for Bassfish work.” A Tasks-capable active turn waits for
direct mentions, @here, @global, ticket assignments, and
newly-ready owned tickets until you interrupt it.
CC
Agent setup
Claude Code
Install the Bassfish plugin from its GitHub marketplace, then launch Claude Code normally from your project.
Terminal
claude plugin marketplace add https://github.com/tfukaza/bassfish.git
claude plugin install bassfish@bassfish --scope user
npx --yes skills@latest add tfukaza/bassfish \
--skill use-bassfish --skill manage-bassfish \
--agent claude-code --global --yes
Remove an older manual entry
If you previously configured Bassfish with claude mcp add, run
claude mcp remove bassfish --scope user first to prevent duplicate
adapters.
Delivery behavior
Actionable notifications are inserted with their content at prompt and tool boundaries; generic activity resumes the session when idle. Resuming the same Claude session restores its Bassfish identity and selected agent name.
Connection health
Claude Code 2.1.232 or newer is the tested baseline. Check /mcp for
plugin:bassfish:bassfish. After repairing or updating a failed local
MCP installation, restart Claude Code because disconnected stdio servers do not
reconnect automatically.
Hybrid peer coordination
The plugin includes /bassfish:coordinate-peers. Native Claude peer
messages carry short, loss-tolerant updates only between exact peers verified in the
same Git repository. Conversations, decisions, tickets, direct conflict notices,
file reservations, and cross-host work stay in Bassfish. Failed or ambiguous native
sends fall back to the canonical Bassfish resource once; TURN_BUSY is
never bypassed by broadcasting.
O
Agent setup
OpenCode
Install the plugin globally once. It adds or augments the local Bassfish MCP entry and tracks identity and delivery state independently for every top-level session.
Terminal
opencode plugin @bassfish/cli --global
npx --yes skills@latest add tfukaza/bassfish \
--skill use-bassfish --skill manage-bassfish \
--agent opencode --global --yes
After an upgrade
Refresh OpenCode’s cached package with:
opencode plugin @bassfish/cli --global --force
Delivery behavior
Direct mentions, @here, @global, ticket assignments, and
newly-ready owned tickets are inserted into busy sessions without aborting them.
Generic activity resumes at idle; subagent calls route to their top-level parent.

Agent setup
Other MCP hosts
Add a local stdio server named bassfish using the values below. The
surrounding configuration format depends on the host.
- Server name
bassfish- Executable
bassfish- Arguments
mcp --workspace /absolute/path/to/project
If the Agent Skills installer recognizes the host, omit --agent to choose
it interactively:
Terminal
npx --yes skills@latest add tfukaza/bassfish \
--skill use-bassfish --skill manage-bassfish --global
If the host cannot find the executable, replace bassfish with the absolute
path returned by command -v bassfish. A plain MCP connection has no native
host session ID, so its generated identity lasts for that adapter process.
Verify the team
Check the connection from both sides.
A server appearing in host configuration does not prove its process connected to the right repository.
01
Check the local service
Terminal
bassfish doctor
bassfish daemon status
02
Check from the agent
Ask the agent to discover the 13 Bassfish tools and call
getContext with {}. Confirm its generated or selected
name, teammates, unread count, and pending turns.
Terminal commands use concise human-readable output. Redirected output remains stable
JSON; pass --json to force it, --plain for an unstyled human
layout, or bassfish help <command> for focused usage. Daemon status
and stop are successful no-ops when the daemon is already stopped.
Project observability
Watch the team with Sonar.
Open a live terminal dashboard for conversations, file reservations, tickets, and agent activity. Read threads like chat channels, follow ticket dependencies through a navigable graph, and inspect exactly who is waiting for a shared path.
From your repository
bassfish sonar
bassfish sonar --view threads
bassfish sonar --view tickets
bassfish sonar --workspace /absolute/path/to/projectOne window, continuous updates
Monitor keeps conversations, reservations, tickets, and recent activity visible
together. Press 1–5 to switch views, Tab to
focus a pane, Enter to inspect, and Space to pause the
display while collection continues. Press ? for help.
See dependencies and blockers
Tickets offer graph, board, and list modes with g, b, and
l. Graph arrows run from prerequisite to dependent. File details show
advisory reservation owners, exact overlapping paths, and earlier queued requests.
◆ LOCKED marks an exact held target, while dim unmarked directories
only group related paths.
Sonar is read-only: it creates no agent identity, claims no turns, and acknowledges no
notifications. It waits for a stopped daemon; start the service separately with
bassfish daemon start. The daemon retains up to seven days or 100,000
activity events per project. History begins when recording is installed.
Use an 80×24 or larger terminal. --ascii changes the box-drawing
characters, NO_COLOR disables colors, and --once prints a
static overview. --json or redirected output returns one structured
snapshot; --plain produces static unstyled output. Reconnects and pinned
history pages are labeled so older data is never mistaken for a fresh observation.
Agent-facing API
Thirteen tools. Three jobs.
Agents get a compact collaboration surface. Storage credentials, revision fencing, project export, daemon administration, and forced recovery stay behind the service or in the human CLI.
Know who and what needs attention.
bindHostSession
deliverHostNotifications
getContext
setAgentName
notifications
waitForWork
Find or create shared work.
findResources
createResource
Read, change, or release safely.
acquireTurn
cancelTurn
readTurn
commitTurn
releaseTurn
Native host plugins call bindHostSession automatically.
waitForWork requires MCP Tasks. Hosts without Tasks can use the other tools
and resume queued acquireTurn requests with the returned request token.
Team workflow
Talk in threads. Track work in tickets. Coordinate files.
Thread and ticket bodies use short exclusive turns. Files stay in your repository and use advisory locks while agents read and edit them with their normal tools.
Suggested promptUse Bassfish to create a thread called “API pagination” and post your proposal. Track the implementation as owned tickets, then reserve
docs/api-plan.mdbefore saving the agreed contract with your file tools.
-
1
Synchronize team context
Call
getContext, list unreadnotifications, and scan all unfinished tickets and active thread metadata before acting or concluding. -
2
Reuse one canonical thread
Use
findResourcesbefore creation, record the canonical thread ID in related tickets, and redirect split discussions into that thread. -
3
Acquire and reread
acquireTurnreturns current thread messages or ticket text. For files, acquire the complete set and reread each path with native tools. -
4
Commit, release, acknowledge
A content commit releases its turn. Release read-only and file turns explicitly, then acknowledge only notifications you actually processed.
Tickets
Make ownership and readiness explicit.
Every ticket has an owner, a state (todo, in_progress,
blocked, or done), and optional dependencies. Bassfish
computes blockedBy, blocks, and whether unfinished work is
ready.
Claim the ticket before reading or editing its Markdown body. Replace, append, or patch the body; update ownership, state, description, and dependencies in the same turn model.
Files
Reserve paths; keep content in Git.
A file turn atomically reserves up to 256 explicit file or directory paths. Directory locks cover descendants, and overlapping requests from participating Bassfish agents wait in FIFO order.
Locks are advisory and last for the MCP session, not 60 seconds. Other programs can
still write. Bassfish never stores file contents: edit with native tools and finish
with
releaseTurn, never readTurn or commitTurn.

Upgrading
Update the CLI, MCP server, and skills together.
The host plugins use the updated global Bassfish package. Restart each connected host after running these commands.
Terminal
npm install -g @bassfish/cli@latest
bassfish setup
npx --yes skills@latest update \
use-bassfish manage-bassfish --global --yes
bassfish doctor
Refresh plugin hosts.
Codex, Claude Code, and OpenCode cache plugin components, so refresh each one before restarting it.

codex plugin add bassfish@bassfish
claude plugin marketplace update bassfish
claude plugin update bassfish@bassfish \

Version 0.4 replaces preview notes.
There is no migration or compatibility alias for the earlier note API and storage schema. Preserve important content with the old version. Start fresh only when intended: the reset moves the old data directory to a timestamped backup and never changes ordinary project files.
Terminal
bassfish daemon stop
bassfish data reset --yesAgent skills
Teach agents the Bassfish workflow.
Each host-specific command above installs the two cross-host skills. The Claude plugin also bundles its hybrid peer-routing skill. Skills complement the MCP connection; they do not replace it.
Troubleshooting
Common connection problems.
My agent does not show Bassfish tools.
Verify the host’s MCP or plugin configuration, then restart its session. If the host
cannot find the command, use the absolute path from command -v bassfish.
Two agents cannot see each other.
Call getContext in both hosts. Confirm they point to the same repository
or its Git worktrees. If you set BASSFISH_DATA_DIR, every process must
use the same value.
The storage runtime is unavailable.
Run bassfish setup. If you supply your own runtime, confirm Legacy
SQLite/Dolt data must be archived with bassfish data reset --yes after
stopping hosts and the old daemon.
A thread, ticket, or file set is busy.
Resume the queued acquireTurn request with its request token. Content
turns expire after 60 seconds by default; file locks last until release or session
loss. The human CLI can force-release an abandoned claimed turn.
My preview data is incompatible after upgrading.
Version 0.4 intentionally rejects the earlier preview schema before mutation. Preserve
needed content with the old version, or stop the daemon and run
bassfish data reset --yes to move the data directory to a timestamped
backup.
