work-plan

name	work-plan
description	This skill should be used when the current work phase is "plan". Provides the planning workflow: reading research notes, building acceptance criteria, creating ordered task lists with parallelization strategy, saving design decisions to _notes/plan-*.md, and transition to implement phase.

work-plan

Plan phase workflow. Primary deliverable: updated _notes/_summary.md with concrete plan and _notes/plan-*.md files with design decisions.

Step 1: Read research

Read all _notes/research-*.md files. Summarize what is known before proposing a plan.

Step 2: Build the plan

Work with the user to create:

Acceptance criteria — clear, testable conditions for "done":

## Acceptance Criteria
- [ ] Auth endpoint returns 401 for expired tokens
- [ ] Refresh token rotation works with Redis TTL
- [ ] SDK client handles token refresh transparently

Ordered task list — concrete steps with file references:

## Plan
1. Add refresh endpoint to `core/pl/pkg/auth/handler.go`
2. Implement token rotation in `core/pl/pkg/auth/token.go`
3. Update SDK client in `core/platforma/sdk/src/auth.ts`
4. Add integration tests in `core/pl/pkg/auth/handler_test.go`

Parallelization strategy — how to split work:

### Work Split
- Group 1 (Go): Tasks 1, 2, 4 — core/pl auth package
- Group 2 (TypeScript): Task 3 — core/platforma SDK

Split rules:

• Different languages -> separate groups. Go and TypeScript never mix.
• Independent modules -> parallel groups.
• Each group should be self-contained with clear inputs/outputs.

Step 3: Save decisions (PRIMARY DELIVERABLE)

Write design decisions, trade-offs, and rationale to _notes/plan-*.md:

File template:

# Plan: <Topic>

Created: YYYY-MM-DD

## Decision

<what was decided>

## Rationale

<why this approach over alternatives>

## Trade-offs

- Pro: <benefit>
- Con: <cost>

File naming: _notes/plan-<topic-slug>.md

Examples:

• "chose gRPC over REST" -> _notes/plan-api-design.md
• "need to modify 3 packages" -> _notes/plan-scope.md
• "migration risk" -> _notes/plan-risks.md

Step 4: Update _summary.md

After plan is agreed:

• Write the full plan to _notes/_summary.md Plan section
• Write acceptance criteria to _notes/_summary.md Acceptance Criteria section
• Link all _notes/plan-*.md files in Work Notes section
• Append to _notes/worklog.md: - YYYY-MM-DD: Plan completed

Step 5: Suggest transition

When the plan is ready:

[PLAN] Plan is complete. Task list, acceptance criteria, and work split are documented.
When ready, use `/work update move to implement` to begin coding.

If unknowns surface during planning:

[PLAN] Discovered unknowns: <list>. Suggest `/work update move to research` to explore before continuing.

Writing rules

• One topic = one file. Each design decision or trade-off gets its own file.
• File naming: _notes/plan-<topic-slug>.md
• Save immediately. Write each decision as it's made — don't wait for the full plan.
• Max 100 lines per file. Split if growing beyond.
• Update the index. Every new file must be linked in _notes/_summary.md Work Notes section.

Completion signals

• Acceptance criteria are specific and testable
• Task list is ordered with concrete file references
• Work split is documented (which groups, which tasks, which repos)
• No unresolved design questions blocking implementation

MANDATORY: Update Notes

After completing ANY action in this skill, you MUST update _notes/worklog.md with a timestamped entry describing what was done. Format:

- YYYY-MM-DD HH:MM: <action summary>

Never skip this step. Notes are the primary deliverable, not a side-effect.
