| description | Turns the current conversation into a spec and publishes it to the project issue tracker, with no interview. Use when the user says "write a spec", "create a PRD", or wants the discussion captured as a spec. |
| disable-model-invocation | true |
This skill takes the current conversation context and codebase understanding and produces a spec (you may know this document as a PRD). Do NOT interview the user — just synthesize what you already know.
The issue tracker and triage label vocabulary should have been provided to you — run /mattpocock:setup-matt-pocock-skills if not.
CRITICAL: No interview — synthesize what you already know
Do NOT interview the user; the spec is a synthesis of the conversation and codebase understanding already in context. Test at the highest existing seam, preferring one seam to many — check the seams with the user before writing.
Process
-
Explore the repo to understand the current state of the codebase, if you haven't already. Use the project's domain glossary vocabulary throughout the spec, and respect any ADRs in the area you're touching.
-
Sketch out the seams at which you're going to test the feature. Existing seams should be preferred to new ones. Use the highest seam possible. If new seams are needed, propose them at the highest point you can. The fewer seams across the codebase, the better - the ideal number is one.
Check with the user that these seams match their expectations.
- Write the spec using the template below, then publish it to the project issue tracker. Apply the
ready-for-agent triage label - no need for additional triage.
Problem Statement
The problem that the user is facing, from the user's perspective.
Solution
The solution to the problem, from the user's perspective.
User Stories
A LONG, numbered list of user stories. Each user story should be in the format of:
- As an , I want a , so that
1. As a mobile bank customer, I want to see balance on my accounts, so that I can make better informed decisions about my spending
This list of user stories should be extremely extensive and cover all aspects of the feature.
Scenarios
Executable scenarios derived from the user stories above, written as Gherkin (Given/When/Then). Each scenario pins one behavior; collectively they are the executable specification the implementation is verified against. See /mattpocock:bdd for the scenario authoring guide and the .feature storage convention.
Implementation Decisions
A list of implementation decisions that were made. This can include:
- The modules that will be built/modified
- The interfaces of those modules that will be modified
- Technical clarifications from the developer
- Architectural decisions
- Schema changes
- API contracts
- Specific interactions
Do NOT include specific file paths or code snippets. They may end up being outdated very quickly.
Exception: if a prototype produced a snippet that encodes a decision more precisely than prose can (state machine, reducer, schema, type shape), inline it within the relevant decision and note briefly that it came from a prototype. Trim to the decision-rich parts — not a working demo, just the important bits.
Testing Decisions
A list of testing decisions that were made. Include:
- A description of what makes a good test (only test external behavior, not implementation details)
- Which modules will be tested
- Prior art for the tests (i.e. similar types of tests in the codebase)
Out of Scope
A description of the things that are out of scope for this spec.
Further Notes
