taskswarm (Python)

Self-hosted event server that pushes a notification the instant a parallel coding-agent session blocks, needs review, fails, or finishes.

Why this exists

Running three or four coding-agent sessions in parallel turns into a tab-switching problem: nothing pushes state to you, so you find out a session has been sitting on a permission prompt for ten minutes only by polling terminals by eye. TaskSwarm closes that gap: every agent session reports its state to a small local HTTP server, and the instant one transitions to blocked, needs-review, failed, or done, TaskSwarm fires a local OS notification and updates a live status page over Server-Sent Events. No polling, no account, no cloud dependency by default.

This package is the Python distribution of TaskSwarm -- a genuine, independent port of the server, CLI, event schema, and notification logic, not a wrapper around the Node binary. It has zero runtime dependencies: no HTTP framework, no schema-validation library, nothing beyond the Python standard library.

Install

Live on PyPI as taskswarm:

pip install taskswarm

or with uv:

uv add taskswarm

The complementary JS/TS distribution is already live on npm as taskswarm-cli (npm install -g taskswarm-cli, or npx taskswarm-cli start with no install step) -- see the project README for that package. Both are first-class and maintained together; neither is a replacement for the other.

Quickstart

# Terminal 1: start the server
taskswarm start
# TaskSwarm server listening on http://127.0.0.1:4173
# Live status page: http://127.0.0.1:4173/?token=<your-token>

# Terminal 2: report a session's status as it works
taskswarm agent report-status --task my-fix --repo ./api --state running
taskswarm agent report-status --task my-fix --repo ./api --state done

Open the live status page URL printed by start. The row for my-fix updates the instant each report-status call lands, no refresh.

Or call the library directly, in-process, without a subprocess:

from taskswarm import start_server
from taskswarm.adapters import GenericAdapter
from taskswarm.client.api_client import post_event

running = start_server()
adapter = GenericAdapter()
event_input = adapter.to_event_input(
    {"session_id": "my-fix", "repo": "./api", "status": "done", "agent_type": "generic"}
)
event = post_event(running.config.to_dict(), event_input)
print(event["session_id"], "->", event["status"])
running.close()

What it does

• Event server, not a board you have to keep open. taskswarm start boots an HTTP+SSE server (stdlib http.server, no framework dependency) that accepts POST /events, serves GET /events for current session state, and streams new events over GET /live (Server-Sent Events) to the bundled live status page.
• Push notification on the four states that mean "look at this now." The moment a session's status transitions to blocked, needs-review, failed, or done, TaskSwarm fires a native OS notification (osascript on macOS, a terminal-bell console fallback elsewhere). Notification dedup keys on the (status, blocked_reason) pair, so a second, different permission prompt still notifies even though the status (needs-review) didn't change.
• A wrapper-script adapter for any agent. taskswarm agent report-status --task <id> --repo <path> --state <state> is the one primitive every integration is built on -- callable from any script wrapping any CLI agent (Codex, Cursor, or anything else).
• A Claude Code hooks adapter, ported with the same behavior as the npm package's: taskswarm hooks install claude-code writes Stop and Notification hook entries into .claude/settings.json, pointed at the exact, already-installed console script on disk (never a floating PATH lookup re-resolved on every hook fire).
• A bearer-token-gated local API, bound to loopback by default. POST /events and the live page both require the token TaskSwarm generates on first run (~/.taskswarm/config.json, written 0600). Rotate it with taskswarm token rotate.
• Agent-native by design. Every subcommand ships a --json flag with a stable schema, including error output.
• ntfy.sh is opt-in, never default. The only notification channel that leaves your machine, and it's off unless you configure it in ~/.taskswarm/config.json.

CLI reference

Command	Description	Key options
taskswarm start	Start the TaskSwarm server and print the live status page URL	--json
taskswarm task add	Register a new task	--title <title> (required), --repo <path> (required), --json
taskswarm task list	List tracked tasks, enriched with live status when the server is reachable	--json
taskswarm agent report-status	Report a status transition for a task/session to the local server	--task <id> (required), --repo <path> (required), --state <state> (required, one of queued|running|blocked|needs-review|done|failed), --blocked-reason <text>, --agent-type <type> (claude-code|codex|cursor|generic, default generic), --json
taskswarm token rotate	Generate a new bearer token, invalidating the old one	--json

taskswarm hooks claude-code-relay	Internal: reads a hook payload from stdin and relays it. Installed automatically; not meant to be run by hand.	none

taskswarm --version prints taskswarm 0.1.0. The taskswarm-cli console script installed by this package is an identical alias, matching both bin entries the npm package ships.

How it works

agent session / hook / wrapper script
        |
        v
POST /events (bearer token required)  -> event schema validation
        |
        v
EventStore (in-memory + append-only JSONL log at ~/.taskswarm/events.jsonl)
        |
        +--> notify() -- fires on a transition into blocked/needs-review/failed/done
        |         |
        |         +--> local OS notification (always on)
        |         +--> ntfy.sh (opt-in only)
        |
        +--> GET /live (Server-Sent Events) -> live status page

Security

The local API is gated by a bearer token generated on first run and stored 0600 at ~/.taskswarm/config.json; the server binds to 127.0.0.1 by default. Token comparison uses hmac.compare_digest (constant-time, avoiding timing side-channels), the same property the TypeScript version gets from crypto.timingSafeEqual. See SECURITY.md for the full posture, including what this server does not protect against (it is a local developer tool, not designed to be exposed on a shared or public network). Honest note: this project does not currently publish SLSA provenance, Sigstore signatures, or an SBOM, and has no OpenSSF Scorecard badge -- none of that infrastructure exists yet for either distribution, so it isn't claimed here.
