# Issue Planner

Design solutions and decompose into implementation tasks. Internally invokes issue-plan-agent for ACE exploration and solution generation. For revision tasks (SOLVE-fix), design alternative approaches addressing reviewer feedback.

## Phase 2: Context Loading

| Input | Source | Required |
|-------|--------|----------|
| Issue ID | Task description (GH-\d+ or ISS-\d{8}-\d{6}) | Yes |
| Explorer context | `<session>/explorations/context-<issueId>.json` | No |
| Review feedback | Task description (for SOLVE-fix tasks) | No |
| .msg/meta.json | <session>/wisdom/.msg/meta.json | No |

1. Extract issue ID from task description via regex: `(?:GH-\d+|ISS-\d{8}-\d{6})`
2. If no issue ID found -> report error, STOP
3. Load explorer context report (if available):

```
Read("<session>/explorations/context-<issueId>.json")
```

4. Check if this is a revision task (SOLVE-fix-N):
   - If yes, extract reviewer feedback from task description
   - Design alternative approach addressing reviewer concerns
5. Load wisdom files for accumulated codebase knowledge

## Phase 3: Solution Generation via CLI

**CLI invocation**:

```
Bash("ccw cli -p \"
PURPOSE: Design solution for issue <issueId> and decompose into implementation tasks; success = solution bound to issue with task breakdown

TASK: • Load issue details from ccw issue status • Analyze explorer context • Design solution approach • Break down into implementation tasks • Generate solution JSON • Bind solution to issue

MODE: analysis

CONTEXT: @**/* | Memory: Issue <issueId> - <issue.title> (Priority: <issue.priority>)
Explorer findings: <explorerContext.key_findings>
Relevant files: <explorerContext.relevant_files>
Complexity: <explorerContext.complexity_assessment>

EXPECTED: Solution JSON with: issue_id, solution_id, approach, tasks (ordered list with descriptions), estimated_files, dependencies
Write to: <session>/solutions/solution-<issueId>.json
Then bind: ccw issue bind <issueId> <solution_id>

CONSTRAINTS: Follow existing patterns | Minimal changes | Address reviewer feedback if SOLVE-fix task
\" --tool gemini --mode analysis", { run_in_background: true })
```

**Expected CLI output**: Solution file path and binding confirmation

**Parse result**:

```
Read("<session>/solutions/solution-<issueId>.json")
```

## Phase 4: Solution Selection & Reporting

**Outcome routing**:

| Condition | Message Type | Action |
|-----------|-------------|--------|
| Single solution auto-bound | `solution_ready` | Report to coordinator |
| Multiple solutions pending | `multi_solution` | Report for user selection |
| No solution generated | `error` | Report failure to coordinator |

Write solution summary to `<session>/solutions/solution-<issueId>.json`.

Update `<session>/wisdom/.msg/meta.json` under `planner` namespace:
- Read existing -> merge `{ "planner": { issue_id, solution_id, task_count, is_revision } }` -> write back
