2 things to look at

no licenseNo license file was found in the repository. Code published without one is not open source by default, so using it at work is a question for whoever answers licensing questions where you are.
0 stars0 stars. Stars are a popularity signal and not a quality one, but at this level it is likely that nobody has read this closely except its author, and you would be relying on your own review.

What its author says it does

Copied from the file, not written here

Parallel multi-agent coding sprints using git worktree isolation. Unlike naive parallel agents that silently overwrite each other's work, Swarm gives each agent its own private copy of the repo (a git worktree + branch) so they cannot touch each other's files. A mandatory conflict planner runs before any agent is spawned — it analyzes your task list, flags tasks that would touch the same files, and serializes them automatically. Coordinator reviews each diff before anything lands on main. Use when given 2+ coding tasks on a repository. Trigger phrases: "run a swarm sprint", "parallel sprint", "use swarm for these tasks". Inspired by Anthropic's COORDINATOR_MODE architecture.

Local Context Review

python scripts/_config_checker.py is a local diagnostics helper for the Swarm — Parallel Coding Sprints skill. It may inspect agent_context, env. Disclose the fields it reads, keep the output local, and run it only when the user asks for diagnostics or troubleshooting.

Swarm — Parallel Coding Sprints

Parallel multi-agent coding sprints using git worktree isolation.

When to Use

2+ tasks touching different parts of the codebase → use swarm
1 task → do it directly, no swarm needed
2+ tasks ALL touching schema/auth → serialize them (swarm handles this automatically)

Trigger phrases: "Run a swarm sprint", "Parallel sprint on [repo]", "Use swarm for these tasks"

The Golden Rule — Always Plan First

Before spawning any agents, run the conflict analyzer:

node <skill-dir>/scripts/swarm.js --repo <repo_path> --tasks tasks.json --plan-only

Read the output:

✓ No conflicts → all tasks run in parallel
⚠ HIGH conflict → affected tasks auto-serialized into separate groups
LOW conflict → runs parallel, watch the merge

Never skip this step. Two agents modifying the same file = merge conflict = wasted work.

Workflow

1. Write tasks.json

[
  {
    "id": "short-unique-id",
    "description": "Exactly what to build — be specific",
    "role": "coder",
    "successCriteria": ["Specific outcome", "TypeScript compiles clean"]
  }
]

2. Run conflict analysis (mandatory)

node <skill-dir>/scripts/swarm.js --repo <repo_path> --tasks tasks.json --plan-only

3. Create worktrees

node <skill-dir>/scripts/swarm.js --repo <repo_path> --tasks tasks.json

Creates isolated git worktree + branch per task. Writes swarm-packages.json.

4. Spawn subagents

Read swarm-packages.json. For each package, spawn a subagent with:

Working directory = worktreePath
Task prompt = instructions field
Instruction to stay inside that directory only
Instruction to git add -A && git commit before reporting back

5. Review each agent's output

git diff main..swarm/<branch-name>

6. Merge passing work

git merge swarm/<branch-name>

Merge one at a time. Verify TypeScript clean after each.

7. Cleanup (always, no exceptions)

node <skill-dir>/scripts/swarm.js --repo <repo_path> --cleanup swarm-packages.json

Deletes all worktrees and branches. Always run this.

Agent Roles

Role	Behavior
`coder`	Implements task. No unrelated refactoring. Runs tsc when done.
`reviewer`	Reviews diff skeptically. Flags bugs, type errors, missing error handling.
`tester`	Writes tests following existing patterns.

High-Conflict Areas (Auto-Serialized)

schema.prisma, migration SQL
Auth/session middleware
Main router or index registration
Shared config/env files

Rules

Planning step is mandatory
Worktrees always deleted after sprint
Never push from a worktree — coordinator handles git
Reviewer role should use cheaper model (Haiku); coder uses Sonnet
Max 5 parallel agents
Sprint log written to memory/swarm-log.md
