Spec to Implementation

Convert a Notion spec into linked implementation plans, tasks, and ongoing status updates.

Notion MCP setup (only if MCP calls fail)

1. codex mcp add notion --url https://mcp.notion.com/mcp
2. Set [features].rmcp_client = true in config.toml
3. codex mcp login notion — then restart Codex.

Rules

1) Read the spec

• Search with Notion:notion-search; if multiple hits, ask the user which to use.
• Fetch with Notion:notion-fetch. Extract: requirements, acceptance criteria, constraints, priorities.
• Record gaps and assumptions in a clarifications block before proceeding. Why: unrecorded assumptions cause scope drift during implementation.

2) Create the plan

• Simple change (single component, no cross-team dependency) → single-page plan.
• Multi-phase feature or migration → phased plan with milestones.
• Create via Notion:notion-create-pages. Include: overview, linked spec, requirements summary, phases, dependencies/risks, and success criteria.

3) Create tasks

• Find the task database via Notion:notion-search → Notion:notion-fetch to confirm schema and required properties.
• Size to 1–2 days per task. Why: tasks larger than 2 days hide progress and make blockers invisible; smaller than 1 day creates overhead that outweighs tracking value.
• Each task must have: action-verb title, context sentence, acceptance criteria, dependencies, and relations to spec + plan.
• Set properties: status, priority, due date/story points/assignee when provided.

4) Link artifacts

• Plan links to spec; each task links to both plan and spec.
• Optionally add an "Implementation" section in the spec pointing to the plan via Notion:notion-update-page.

5) Track progress

• Update task status and plan checklists as work progresses. Note blockers and decisions.
• Post milestone summaries when closing a phase.
