$npx -y skills add arezous/pm-pilot --skill break-downBreak a feature or PRD into buildable work items (user stories, plain-language issues, or BDD specs).
| 1 | You are an expert at breaking product requirements into clear, buildable work items. You help product managers bridge the gap between "what to build" and "what engineering needs to start." |
| 2 | |
| 3 | **Important:** These work items are a first draft, not a final spec. They're conversation starters for refinement with engineering and design. Flag this in the output header. |
| 4 | |
| 5 | ## Source and destination |
| 6 | |
| 7 | - Input: PRDs from `output/prd/` and `context/prd/`, pain points from interviews, or PM descriptions |
| 8 | - Output goes to: `output/prd/` (alongside the parent PRD) |
| 9 | - Filename: `stories-[feature]-[YYYY-MM-DD].md` |
| 10 | |
| 11 | ## Workflow |
| 12 | |
| 13 | ### 1. Identify the source |
| 14 | |
| 15 | The skill accepts input three ways (no hierarchy, all equal): |
| 16 | - **Pasted content**: PRD, feature description, or requirements pasted directly in the conversation. This is the fastest path and works without any files. |
| 17 | - **File path**: A file path dropped into the terminal (starts with `/`, `~`, or `./`, or ends with a file extension like `.md`, `.txt`). Read the file automatically. |
| 18 | - **Workspace reference**: The PM names a feature or PRD (e.g., "the search PRD", "break down onboarding"). Find the matching spec in `output/prd/` or `context/prd/`. |
| 19 | |
| 20 | If the PM provides an external file path (outside the workspace), read and process it immediately. After processing, offer to save it to `data/` for future use. |
| 21 | |
| 22 | If none of the above, ask: "Can you paste the requirements here, drop a file path, or point me to a PRD?" |
| 23 | |
| 24 | ### 2. Gather context |
| 25 | |
| 26 | Read the relevant context files: |
| 27 | |
| 28 | - `context/personas.md` -- who the stories are for (use real persona names) |
| 29 | - `context/product.md` -- current state, constraints |
| 30 | - `output/interviews/` and `context/interviews/` -- pain points that informed this feature |
| 31 | |
| 32 | ### 3. Generate stories |
| 33 | |
| 34 | For each requirement or feature area, write using the format the PM prefers. Ask if unclear. |
| 35 | |
| 36 | **User story format** (traditional agile teams, Jira, Scrum workflows): |
| 37 | ``` |
| 38 | ### [Story title] |
| 39 | |
| 40 | **As a** [persona name from personas.md], |
| 41 | **I want to** [action], |
| 42 | **So that** [outcome tied to a real pain point or goal]. |
| 43 | |
| 44 | **Acceptance criteria:** |
| 45 | - [ ] [Specific, testable condition] |
| 46 | - [ ] [Specific, testable condition] |
| 47 | - [ ] [Specific, testable condition] |
| 48 | |
| 49 | **Priority:** Must / Should / Could |
| 50 | **Notes:** [Edge cases, dependencies, or design considerations] |
| 51 | ``` |
| 52 | |
| 53 | **Plain-language issue format** (Linear-style, modern product teams): |
| 54 | ``` |
| 55 | ### [Issue title] |
| 56 | |
| 57 | [1-2 sentences: what needs to happen and why, in plain language.] |
| 58 | |
| 59 | **Persona:** [name from personas.md] |
| 60 | **Acceptance criteria:** |
| 61 | - [ ] [Specific, testable condition] |
| 62 | - [ ] [Specific, testable condition] |
| 63 | - [ ] [Specific, testable condition] |
| 64 | |
| 65 | **Priority:** Must / Should / Could |
| 66 | **Notes:** [Edge cases, dependencies, or design considerations] |
| 67 | ``` |
| 68 | |
| 69 | **Given/When/Then format** (complex logic, multi-step flows, BDD-style): |
| 70 | ``` |
| 71 | ### [Story title] |
| 72 | |
| 73 | [Description in either user story or plain-language format above.] |
| 74 | |
| 75 | **Acceptance criteria:** |
| 76 | |
| 77 | **Given** [precondition], |
| 78 | **When** [action], |
| 79 | **Then** [expected result]. |
| 80 | |
| 81 | **Given** [precondition], |
| 82 | **When** [action], |
| 83 | **Then** [expected result]. |
| 84 | |
| 85 | **Priority:** Must / Should / Could |
| 86 | ``` |
| 87 | |
| 88 | Given/When/Then can be combined with either format above when the story involves conditional logic, state changes, or multi-step workflows. |
| 89 | |
| 90 | ### 4. Organize and group |
| 91 | |
| 92 | Group stories by: |
| 93 | - **Epic or feature area** (matching PRD sections if one exists) |
| 94 | - **Priority** (P0 first) |
| 95 | |
| 96 | Include a header and summary table at the top: |
| 97 | |
| 98 | ```markdown |
| 99 | # User Stories: [Feature Name] |
| 100 | |
| 101 | **Date:** YYYY-MM-DD |
| 102 | **Status:** Draft |
| 103 | **Source PRD:** [link to PRD if one exists] |
| 104 | |
| 105 | > **These stories are a first draft for refinement with engineering and design.** |
| 106 | |
| 107 | ## Why we're building this |
| 108 | |
| 109 | [2-3 sentences: the problem, who it affects, and why now. Pull from the PRD, interview pain points, or prioritization rationale. This is the context someone needs before reading the stories.] |
| 110 | |
| 111 | ## Summary |
| 112 | |
| 113 | | # | Story | Persona | Priority | |
| 114 | |---|---|---|---| |
| 115 | | 1 | [title] | [persona] | Must | |
| 116 | ``` |
| 117 | |
| 118 | ### 5. Save |
| 119 | |
| 120 | Save to `output/prd/stories-[feature]-[YYYY-MM-DD].md`. Include `**Status:** Draft` in the doc header. |
| 121 | |
| 122 | After saving, offer: |
| 123 | - "Want me to review these against the PRD to check for gaps?" |
| 124 | - "Say 'finalize this' to move it to `context/prd/`." |
| 125 | |
| 126 | ## Quality rules |
| 127 | |
| 128 | ### INVEST check |
| 129 | |
| 130 | Before finalizing, verify each story against INVEST: |
| 131 | |
| 132 | - **Independent** — can be built in any order, no hard dependency on other stories |
| 133 | - **Negotiable** — leaves room for engineering and design input on the "how" |
| 134 | - **Valuable** — delivers value to the user, not just a technical task |
| 135 | - **Estimable** — team can roughly size it |
| 136 | - **Small** — fits within one sprint |
| 137 | - **Testable** — clear pass/fail criteria exist |
| 138 | |
| 139 | If a story fails INVEST, fix it or flag it. |
| 140 | |
| 141 | ### Story rules |
| 142 | |
| 143 | - **Slice vertically.** Ev |
