plan-swarm

A command that carries out a development plan by assigning independent tasks to several agents at the same time.

In plain words
What is it for?
Executing implementation, bug-fix, or code-quality plan files with a chosen number of parallel workers and completion checks.
Why use it?
It reduces waiting when parts of a plan can be completed independently and keeps tasks coordinated according to their dependencies.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

plan-swarm scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Plan Swarm Command

Execute a plan file using parallel worker agents. Requires a plan file. All workers complete → done.

Note: Loop and swarm are interchangeable - swarm is just faster when tasks can run in parallel. Both enforce exit criteria and sync state.

Uses Claude Code's built-in Task Management System for dependency tracking and visual progress (ctrl+t).

Supported Plan Types

This command works with plans from:

  • /plan-creator - Implementation plans
  • /bug-plan-creator - Bug fix plans
  • /code-quality-plan-creator - LSP-powered quality plans

Arguments

  • <plan_path> (required): Path to the plan file
  • --workers N (optional): Max concurrent workers (default: 3)
  • --model MODEL (optional): Model for workers: haiku, sonnet, opus (default: sonnet)

Instructions

Step 1: Read the Plan (Only)

Read the plan file and extract tasks. DO NOT read other files, grep, or explore the codebase - just parse the plan:

  1. Files to Edit - existing files that need modification
  2. Files to Create - new files to create
  3. Implementation Plan - per-file implementation instructions
  4. Requirements - acceptance criteria
  5. Exit Criteria - verification script and success conditions
  6. Dependency Graph - file dependency phases for execution ordering

Step 2: Create Task Graph

Create a task for each work item and build an ID map as you go:

TaskCreate({ "subject": "Create auth types", ... })        // → task "1"
TaskCreate({ "subject": "Implement auth middleware", ... }) // → task "2"
TaskCreate({ "subject": "Add route protection", ... })     // → task "3"
TaskCreate({ "subject": "Run exit criteria", ... })        // → task "4"

Full TaskCreate per item:

TaskCreate({
  "subject": "Implement auth middleware",
  "description": "Full implementation details from plan - self-contained",
  "activeForm": "Implementing auth middleware"
})

Translate the plan's ## Dependency Graph table to addBlockedBy. The plan contains a table mapping files to phases and dependencies — use it to set up the task graph:

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
