parallel-tracks

A planning method for splitting a large development task into two to four independent work streams that can run at the same time. It also defines dependencies and how the streams fit together.

In plain words
What is it for?
Use it to divide architecture, implementation, testing, or other independent parts of a complex software project into coordinated parallel tracks.
Why use it?
It reduces waiting between unrelated tasks and gives each stream a clear scope, which helps avoid coordination problems during large changes.

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

parallel-tracks 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.

Parallel Tracks Skill

Version: 1.0 Author: Tres Pies Design Purpose: Provide a structured, repeatable process for planning and executing large development tasks in parallel, significantly reducing timelines while improving focus and architectural discipline.


I. The Philosophy: From Sequence to Simultaneity

In complex software development, the default is sequential execution: one task must finish before the next can begin. This creates bottlenecks, extends timelines, and reduces cognitive focus. The Parallel Tracks Pattern is a shift from sequence to simultaneity.

This skill provides a framework for identifying natural boundaries within a large body of work and splitting it into independent, self-contained tracks that can be executed concurrently. It is not merely about doing things at the same time; it is a disciplined practice of upfront architectural planning, rigorous specification, and clear dependency management that makes parallel execution possible.

The math:

  • Sequential: Track A (1 week) + Track B (1 week) + Track C (1 week) = 3 weeks
  • Parallel: Track A + Track B + Track C (all 1 week) = 1 week
  • Typical reduction: 50-70% when done correctly

II. When to Use This Skill

Use when ALL of these conditions are met:

  • The task is large enough: >2 weeks of sequential work as a rule of thumb
  • Clear separation of concerns exists: The work can be cleanly divided by layer, feature, or component
  • Multiple agents or developers are available to work simultaneously
  • Tracks have minimal dependencies on each other
  • You are committed to writing self-contained specifications for each track

Do NOT use when:

  • The task is small (<2 weeks sequential)
  • The work is tightly coupled with no natural boundaries
  • Only one agent/developer is available
  • The specifications cannot be written independently

III. The 6-Step Workflow

Step 1: Identify Natural Boundaries

Analyze the total scope and find clean separation points. Target 2-4 substantial tracks.

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.
