Invoke the technical-planning skill for this conversation.

⚠️ ZERO OUTPUT RULE: Do not narrate your processing. Produce no output until a step or reference file explicitly specifies display content. No "proceeding with...", no discovery summaries, no routing decisions, no transition text. Your first output must be content explicitly called for by the instructions.

Workflow Context

This is Phase 4 of the six-phase workflow:

Phase Focus You

1. Research EXPLORE - ideas, feasibility, market, business

2. Discussion WHAT and WHY - decisions, architecture, edge cases

3. Specification REFINE - validate into standalone spec

4. Planning HOW - phases, tasks, acceptance criteria ◀ HERE

5. Implementation DOING - tests first, then code

6. Review VALIDATING - check work against artifacts

Stay in your lane: Create the plan - phases, tasks, and acceptance criteria. Don't jump to implementation or write code. The specification is your sole input; transform it into actionable work items.

Instructions

Follow these steps EXACTLY as written. Do not skip steps or combine them. Present output using the EXACT format shown in examples - do not simplify or alter the formatting.

CRITICAL: This guidance is mandatory.

• After each user interaction, STOP and wait for their response before proceeding

• Never assume or anticipate user choices

• Even if the user's initial prompt seems to answer a question, still confirm with them at the appropriate step

• Complete each step fully before moving to the next

• Do not act on gathered information until the skill is loaded - it contains the instructions for how to proceed

Step 0: Run Migrations

This step is mandatory. You must complete it before proceeding.

Invoke the /migrate skill and assess its output.

If files were updated: STOP and wait for the user to review the changes (e.g., via git diff ) and confirm before proceeding to Step 1. Do not continue automatically.

If no updates needed: Proceed to Step 1.

Step 1: Discovery State

!.claude/skills/start-planning/scripts/discovery.sh

If the above shows a script invocation rather than YAML output, the dynamic content preprocessor did not run. Execute the script before continuing:

.claude/skills/start-planning/scripts/discovery.sh

If YAML content is already displayed, it has been run on your behalf.

Parse the discovery output to understand:

From specifications section:

• exists

• whether any specifications exist

• feature

• list of feature specs (name, status, has_plan, plan_status, has_impl, impl_status)

• crosscutting

• list of cross-cutting specs (name, status)

• counts.feature

• total feature specifications

• counts.feature_ready

• feature specs ready for planning (concluded + no plan)

• counts.feature_with_plan

• feature specs that already have plans

• counts.feature_actionable_with_plan

• specs with plans that are NOT fully implemented

• counts.feature_implemented

• specs with impl_status: completed

• counts.crosscutting

• total cross-cutting specifications

From plans section:

• exists

• whether any plans exist

• files

• each plan's name, format, status, and plan_id (if present)

• common_format

• the output format if all existing plans share the same one; empty string otherwise

From state section:

• scenario
• one of: "no_specs" , "nothing_actionable" , "has_options"

IMPORTANT: Use ONLY this script for discovery. Do NOT run additional bash commands (ls, head, cat, etc.) to gather state - the script provides everything needed.

→ Proceed to Step 2.

Step 2: Route Based on Scenario

Use state.scenario from the discovery output to determine the path:

If scenario is "no_specs"

No specifications exist yet.

Output the next fenced block as a code block:

Planning Overview

No specifications found in .workflows/specification/

The planning phase requires a concluded specification. Run /start-specification first.

STOP. Do not proceed — terminal condition.

If scenario is "nothing_actionable"

Specifications exist but none are actionable — all are still in-progress and no plans exist to continue.

→ Proceed to Step 3 to show the state.

If scenario is "has_options"

At least one specification is ready for planning, or an existing plan can be continued or reviewed.

→ Proceed to Step 3 to present options.

Step 3: Present Workflow State and Options

Load display-state.md and follow its instructions as written.

→ Proceed to Step 4.

Step 4: Route by Plan State

Check whether the selected specification already has a plan (from has_plan in discovery output).

If no existing plan (fresh start)

→ Proceed to Step 5 to gather context before invoking the skill.

If existing plan (continue or review)

The plan already has its context from when it was created. Skip context gathering.

→ Go directly to Step 7 to invoke the skill.

Step 5: Gather Additional Context

Output the next fenced block as markdown (not a code block):

· · · · · · · · · · · · Any additional context since the specification was concluded?

• c/continue — Continue with the specification as-is
• Or provide additional context (priorities, constraints, new considerations) · · · · · · · · · · · ·

STOP. Wait for user response.

→ Proceed to Step 6.

Step 6: Surface Cross-Cutting Context

Load cross-cutting-context.md and follow its instructions as written.

→ Proceed to Step 7.

Step 7: Invoke the Skill

Before invoking the processing skill, save a session bookmark.

Output the next fenced block as a code block:

Saving session state so Claude can pick up where it left off if the conversation is compacted.

.claude/hooks/workflows/write-session-state.sh
"{topic}"
"skills/technical-planning/SKILL.md"
".workflows/planning/{topic}/plan.md"

Load invoke-skill.md and follow its instructions as written.
