012-agile-epicGuides the creation of agile epics with comprehensive definition including business value, success criteria, and breakdown into user stories.
012 Agile Epic is an agent skill from jabrena/plinth. Guides the creation of agile epics with comprehensive definition including business value, success criteria, and breakdown into user stories. Use when the user wants to create an agile epic, define large bodies of work, break down features into user stories, or document strategic initiatives. This should trigger for requests such as Create an agile epic; Write an epic; I need to create an epic; Define an epic; Epic definition. Part of Plinth Toolkit
Its SKILL.md is about 860 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/012-agile-epic.md`).
It sits in Product & Project Management, covering User stories. The repository describes itself as: Plinth is an AI-native engineering toolkit for modern Java enterprise SDLC, built around reusable Commands, Agents, Skills, and MCP Servers. The licence is Apache-2.0.
Read from SKILL.md and the folder at commit dca88dc. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
012 Agile Epic loads about 859 tokens when it runs, and up to ~2.8k if it reads all its reference files. Until then it costs about 117 tokens; SKILL.md has 393 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

.claude/skills/012-agile-epic/SKILL.md (or your agent's skills folder). This skill also uses 1 other file; get the full folder from GitHub.Guide the agent to systematically gather information and generate a comprehensive epic definition in Markdown format. An epic represents a large body of work that can be broken down into smaller user stories, features, or tasks. This is an interactive SKILL.
What is covered in this Skill?
Before generating the epic document, gather all required information through structured questions. Use exact wording from the template and wait for user responses. Always get current date before starting.
Run date before starting and use it to replace all date placeholders in the generated epic document.
Ask the template questions in strict order, using exact wording and waiting for user responses before continuing.
Step constraints:
Create the epic Markdown with all required sections (scope, value, features, dependencies, risks, and success criteria) and apply the actual current date.
Close with actionable next steps for story breakdown, planning, and epic tracking.
For detailed guidance, examples, and constraints, see references/012-agile-epic.md.

Guides the creation of agile epics with comprehensive definition including business value, success criteria, and breakdown into user stories. 012 Agile Epic is an agent skill from jabrena/plinth. Guides the creation of agile epics with comprehensive definition including business value, success criteria, and breakdown into user stories.
012 Agile Epic fits situations like: the user wants to create an agile epic; define large bodies of work; break down features into user stories; document strategic initiatives.
Run `npx skills add jabrena/plinth --skill 012-agile-epic -a claude-code`. Or copy the skill folder (skills/012-agile-epic in jabrena/plinth) into .claude/skills/012-agile-epic in your project. Claude Code loads it when a task matches its description.
Run `npx skills add jabrena/plinth --skill 012-agile-epic -a codex`. Or copy the skill folder (skills/012-agile-epic in jabrena/plinth) into .agents/skills/012-agile-epic in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add jabrena/plinth --skill 012-agile-epic -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/012-agile-epic, .gemini/skills/012-agile-epic, .github/skills/012-agile-epic and .opencode/skills/012-agile-epic in your project.
SKILL.md names no scripts, command-line tools or credentials: 012 Agile Epic is instructions for the agent only.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
012 Agile Epic is published under the Apache-2.0 licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.
About 859 tokens (SKILL.md is roughly 3.4k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 1.9k tokens, read only when the agent opens those files.
