to-spec

This skill takes the current conversation context and codebase understanding and produces a spec. Do NOT interview the user; just synthesize what you already know.

Read docs/agents/issue-tracker.md and the configured triage vocabulary before publishing. Follow its ownership, Project mapping, and final PR policy. If tracker configuration is absent, tell the user to run /setup-matt-pocock-skills.

Process

1. 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.

2. 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.

1. Write the spec using the template below, then publish it to the project issue tracker. Apply the configured ready-for-agent triage label.

   For GitHub, assign a new PRD to the developer driving the session (the authenticated gh api user --jq .login unless the user identifies another developer). Reuse an existing idea/PRD issue when supplied or when resuming, retaining its assignees and current progress unless the user requested a change. Follow the tracker document to ensure membership in the selected Project and initialize a new work item as todo; retries preserve existing status. Project updates apply only when configured, and use its Status field rather than lifecycle labels.

2. Fetch the published issue and, when configured, its Project item. Verify the URL, body, readiness label, assignees, membership, and expected Status. Report publication or tracking failures separately with the existing URL so a retry updates that issue instead of creating a duplicate. Keep the issue open; publication reserves the work and does not start implementation.

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:

1. As an , I want a , so that

This list of user stories should be extremely extensive and cover all aspects of the feature.

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

Any further notes about the feature.
