write-epic

write-epic is a skill for Claude Code, Codex from cpliakas/claude-code-engineering-leaders. It costs 21 tokens per session (699 once invoked), scanned A, original, MIT.

A planning template for a large software or product initiative, often called an epic. It records the problem, the measures of success, and what the work does and does not include.

In plain words
What is it for?
Use it to define initiatives such as account login, payment changes, or a major product area, and to give smaller development tasks a clear direction.
Why use it?
It turns a broad idea into shared boundaries and outcomes before detailed implementation begins. This helps prevent unclear expectations and uncontrolled expansion of the work.

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

write-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 5d 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.

Write Epic

Write a complete epic specification with scope, success criteria, and scope boundaries.

Input

$ARGUMENTS = epic title and high-level description of the initiative.

Process

1. Handle Missing Input

If $ARGUMENTS is empty or contains no actionable description, prompt the user for the minimum information needed:

  • Epic title — a concise name for the initiative.
  • Brief description — what problem or opportunity does this epic address?

Do not proceed until the user has provided at least a title and a one-sentence description.

2. Gather Context

  • Read the project's CLAUDE.md for architecture, conventions, and strategic context
  • Scan for a roadmap or backlog file if one exists (Glob for roadmap*, backlog*, TODO*)
  • Identify existing work that this epic relates to or depends on

3. Define the Epic

Title: Scoped and outcome-oriented.

  • Good: "User Authentication — Email and OAuth Login"
  • Bad: "Auth stuff" or "Sprint 4 work"

Epic specification body:

## Problem Statement
[1-2 sentences: What problem does this solve? Who is affected? What happens if
we do nothing?]

## Desired Outcome
[1-2 sentences: What does success look like when this epic is complete?]

## Success Metrics
- [Measurable indicator 1]
- [Measurable indicator 2]

## Scope

**In scope:**
- [Capability or deliverable that IS included]

**Out of scope:**
- [Capability explicitly excluded — prevents scope creep]

**Non-goals:**
- [Things this epic intentionally does NOT try to achieve]

## Dependencies and Risks
- **Depends on**: [other epics, services, decisions, or infrastructure]
- **Blocks**: [what downstream work is waiting on this epic]
- **Risks**: [technical unknowns, external dependencies, capacity concerns]

4. Validate the Epic

Check the overall epic before finalizing:

  • Right-sized: spans multiple sprints but delivers value each sprint
  • Strategically aligned: connects to a clear user or business need
  • Measurable: success metrics are specific and verifiable
  • Scoped: in-scope and out-of-scope are explicit — no ambiguity about boundaries

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.
