<purpose>
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.

<step name="parse_arguments">
Parse the command arguments:
- First argument: integer phase number to insert after
- Remaining arguments: phase description

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

If arguments missing:

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

Exit.

Validate first argument is an integer.

Check `roadmap_exists` from init JSON. If false:

</step>

<step name="insert_phase">
**Delegate the phase insertion to `gsd_run query phase.insert`:**

```bash
RESULT=$(gsd_run query phase.insert "${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`.
</step>

<step name="update_project_state">
Update STATE.md to reflect the inserted phase via SDK handlers (never raw
`Edit`/`Write` — projects may ship a `protect-files.sh` PreToolUse hook that
blocks direct STATE.md writes):

1. Update STATE.md's next-phase pointer(s) to the newly inserted phase
   `{decimal_phase}`:

   ```bash
   gsd_run query state.patch '{"Current Phase":"{decimal_phase}","Next recommended run":"/gsd:plan-phase {decimal_phase}"}'
   ```

   (Adjust field names to whatever pointers STATE.md exposes — the handler
   reports which fields it matched.)

2. Append a Roadmap Evolution entry via the dedicated handler. It creates the
   `### Roadmap Evolution` subsection under `## Accumulated Context` if missing
   and dedupes identical entries:

   ```bash
   gsd_run query state.add-roadmap-evolution \
     --phase {decimal_phase} \
     --action inserted \
     --after {after_phase} \
     --note "{description}" \
     --urgent
   ```

   Expected response shape: `{ added: true, entry: "- Phase ... (URGENT)" }`
   (or `{ added: false, reason: "duplicate", entry: ... }` on replay).

## Next Up

**Phase {decimal_phase}: {description}** -- urgent insertion

`/clear` then:

`/gsd:plan-phase {decimal_phase}`

**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_run query phase.insert` executed successfully
- [ ] Phase directory created
- [ ] Roadmap updated with new phase entry (includes "(INSERTED)" marker)
- [ ] `gsd_run query state.add-roadmap-evolution ...` returned `{ added: true }` or `{ added: false, reason: "duplicate" }`
- [ ] `gsd_run query state.patch` returned matched next-phase pointer field(s)
- [ ] User informed of next steps and dependency implications
