brownfield-create-epic

brownfield-create-epic is a command for Claude Code from gonewx/TaskSentinel. It costs 0 tokens per session (983 once invoked), scanned A, original, MIT.

A command for creating one focused work epic in an existing software project. An epic is a larger piece of work that can be divided into a small number of implementation stories.

In plain words
What is it for?
Analyzing the existing project and creating an epic for an isolated change that fits roughly one to three stories and follows established patterns.
Why use it?
It provides a lightweight planning path for small, low-risk enhancements that do not need full product and architecture documents.

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

brownfield-create-epic 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 4d 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.

/brownfield-create-epic Task

When this command is used, execute the following task:

Create Brownfield Epic Task

Purpose

Create a single epic for smaller brownfield enhancements that don't require the full PRD and Architecture documentation process. This task is for isolated features or modifications that can be completed within a focused scope.

When to Use This Task

Use this task when:

  • The enhancement can be completed in 1-3 stories
  • No significant architectural changes are required
  • The enhancement follows existing project patterns
  • Integration complexity is minimal
  • Risk to existing system is low

Use the full brownfield PRD/Architecture process when:

  • The enhancement requires multiple coordinated stories
  • Architectural planning is needed
  • Significant integration work is required
  • Risk assessment and mitigation planning is necessary

Instructions

1. Project Analysis (Required)

Before creating the epic, gather essential information about the existing project:

Existing Project Context:

  • Project purpose and current functionality understood
  • Existing technology stack identified
  • Current architecture patterns noted
  • Integration points with existing system identified

Enhancement Scope:

  • Enhancement clearly defined and scoped
  • Impact on existing functionality assessed
  • Required integration points identified
  • Success criteria established

2. Epic Creation

Create a focused epic following this structure:

Epic Title

{{Enhancement Name}} - Brownfield Enhancement

Epic Goal

{{1-2 sentences describing what the epic will accomplish and why it adds value}}

Epic Description

Existing System Context:

  • Current relevant functionality: {{brief description}}
  • Technology stack: {{relevant existing technologies}}
  • Integration points: {{where new work connects to existing system}}

Enhancement Details:

  • What's being added/changed: {{clear description}}
  • How it integrates: {{integration approach}}
  • Success criteria: {{measurable outcomes}}

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.
