msd-core/get-shit-done/workflows/insert-phase.md

Insert a decimal phase for urgent work discovered mid-milestone between existing integer phases. Uses decimal numbering (72.1, 72.2, etc.) to preserve the logical sequence of planned phases while accommodating urgent insertions without renumbering the entire roadmap.

<required_reading> Read all files referenced by the invoking prompt's execution_context before starting. </required_reading>

Parse the command arguments: - First argument: integer phase number to insert after - Remaining arguments: phase description

Example: /gsd:insert-phase 72 Fix critical auth bug -> after = 72 -> description = "Fix critical auth bug"

If arguments missing:

ERROR: Both phase number and description required
Usage: /gsd:insert-phase <after> <description>
Example: /gsd:insert-phase 72 Fix critical auth bug

Exit.

Validate first argument is an integer.

Load phase operation context:

INIT=$(node ~/.claude/get-shit-done/bin/gsd-tools.cjs init phase-op "${after_phase}")

Check roadmap_exists from init JSON. If false:

ERROR: No roadmap found (.planning/ROADMAP.md)

Exit.

**Delegate the phase insertion to gsd-tools:**

RESULT=$(node ~/.claude/get-shit-done/bin/gsd-tools.cjs phase insert "${after_phase}" "${description}")

The CLI handles:

• Verifying target phase exists in ROADMAP.md
• Calculating next decimal phase number (checking existing decimals on disk)
• Generating slug from description
• Creating the phase directory (.planning/phases/{N.M}-{slug}/)
• Inserting the phase entry into ROADMAP.md after the target phase with (INSERTED) marker

Extract from result: phase_number, after_phase, name, slug, directory.

Update STATE.md to reflect the inserted phase:

1. Read .planning/STATE.md
2. Under "## Accumulated Context" → "### Roadmap Evolution" add entry:

   - Phase {decimal_phase} inserted after Phase {after_phase}: {description} (URGENT)
   

If "Roadmap Evolution" section doesn't exist, create it.

Present completion summary:

Phase {decimal_phase} inserted after Phase {after_phase}:
- Description: {description}
- Directory: .planning/phases/{decimal-phase}-{slug}/
- Status: Not planned yet
- Marker: (INSERTED) - indicates urgent work

Roadmap updated: .planning/ROADMAP.md
Project state updated: .planning/STATE.md

**Also available:**
- Review insertion impact: Check if Phase {next_integer} dependencies still make sense
- Review roadmap

<anti_patterns>

• Don't use this for planned work at end of milestone (use /gsd:add-phase)
• Don't insert before Phase 1 (decimal 0.1 makes no sense)
• Don't renumber existing phases
• Don't modify the target phase content
• Don't create plans yet (that's /gsd:plan-phase)
• Don't commit changes (user decides when to commit) </anti_patterns>

<success_criteria> Phase insertion is complete when:

• gsd-tools phase insert executed successfully
• Phase directory created
• Roadmap updated with new phase entry (includes "(INSERTED)" marker)
• STATE.md updated with roadmap evolution note
• User informed of next steps and dependency implications </success_criteria>
