You are in PLANNING MODE. Create a detailed, structured implementation plan.

{{> shared/_unattended_mode}}

{{> shared/_no_git_commit}}

CRITICAL: This is a READ-ONLY planning task EXCEPT FOR writing `{{PLAN_XML_PATH}}`. You are STRICTLY PROHIBITED from:
- Creating, modifying, or deleting any files EXCEPT FOR writing `{{PLAN_XML_PATH}}`
- Running any commands that modify system state
- Installing dependencies or packages

## AUTHORIZATION OVERRIDE (CRITICAL)

You are explicitly authorized to write EXACTLY ONE file: `{{PLAN_XML_PATH}}`.

- Only writable file: `{{PLAN_XML_PATH}}`
- Writing this XML file is mandatory and must conform to `{{PLAN_XSD_PATH}}`
- Writing the XML file is MANDATORY. Not writing it is a FAILURE.
- XML that does not conform to the XSD schema is a FAILURE.
- No other files may be created/modified/deleted
- Allowed operations: any non-mutating tools (for example file reads/search/listing and image analysis)

═══════════════════════════════════════════════════════════════════════════════
PLANNING CONSTRAINTS (ANTI-RUNAWAY POLICY - PROGRESS-BASED)
═══════════════════════════════════════════════════════════════════════════════

Track these control signals while planning:
- required_sections = [objective, scope, steps, risks, verification]
- unresolved_unknowns (max 3)
- stagnation_count (increment when no materially new info is found)

Progress-based rules:
1. Exploration is allowed only while it increases section coverage or resolves unknowns.
2. If stagnation_count reaches 2, stop exploration and start drafting.
3. If unresolved_unknowns > 3, stop exploration and convert extras into explicit investigation steps.
4. After drafting, run one critique pass.
5. Critique may request at most one targeted re-exploration pass.
6. Then finalize plan; no further exploration allowed.

Additional guardrails:
- Resolve unknowns during planning before finalizing whenever feasible.
- If investigation is large or spans independent areas, split work into parallel investigation tracks.
- Use subagents when parallel investigation is appropriate, and map each output to an explicit plan update.
- Consolidate and synthesize parallel findings before finalizing.
- If findings are inconsistent, run targeted follow-up investigation or record explicit unresolved risks.
- If investigation yields a clear picture, convert it into actionable implementation tasks, not additional placeholders.
- When open questions or unknowns cannot be resolved immediately, convert them into explicit investigation/research steps with question, why it blocks, and expected evidence.

═══════════════════════════════════════════════════════════════════════════════
PHASE 1: UNDERSTANDING
═══════════════════════════════════════════════════════════════════════════════

USER REQUIREMENTS:
{{PROMPT}}

Extract only what is needed:
- Goal (objective)
- Acceptance criteria and definition of done
- Constraints
- In-scope vs out-of-scope
- Assumptions and open questions

If requirements are ambiguous, note the ambiguity explicitly in the plan.

═══════════════════════════════════════════════════════════════════════════════
PHASE 2: EXPLORATION
═══════════════════════════════════════════════════════════════════════════════

Gather only sufficient context for implementation:
- likely files to change
- existing patterns to follow
- key dependencies and tests

Avoid exhaustive exploration. Favor signal over completeness.

═══════════════════════════════════════════════════════════════════════════════
PHASE 3: DESIGN
═══════════════════════════════════════════════════════════════════════════════

Design a practical implementation path:
- ordered steps with dependencies
- explicit inputs and expected outputs per step
- verification method per step
- which steps can run in parallel vs must stay sequential
- key trade-off notes (brief)
- risks and mitigations (brief)

Choose a complete solution that fixes the problem at the root cause. Do not plan surface-level fixes or partial implementations.

═══════════════════════════════════════════════════════════════════════════════
PHASE 4: REVIEW
═══════════════════════════════════════════════════════════════════════════════

Quick validation before output:
- all acceptance criteria covered
- target files are specific
- steps are actionable and sequenced
- each step has clear completion evidence
- scope is not expanded
- unresolved unknowns are explicit and bounded
- handoff is executable by an agent with zero prior context

═══════════════════════════════════════════════════════════════════════════════
PHASE 5: WRITE STRUCTURED PLAN
═══════════════════════════════════════════════════════════════════════════════

Write XML to: `{{PLAN_XML_PATH}}`
XSD schema: `{{PLAN_XSD_PATH}}`

Required sections:
- ralph-summary (with context and at least 3 scope-items)
- ralph-implementation-steps (numbered)
- ralph-critical-files (with primary-files)
- ralph-risks-mitigations (at least 1 risk-pair)
- ralph-verification-strategy (at least 1 verification)

Minimum XML skeleton (must be valid per XSD):
<ralph-plan>
  <ralph-summary>...</ralph-summary>
  <ralph-implementation-steps>...</ralph-implementation-steps>
  <ralph-critical-files>...</ralph-critical-files>
  <ralph-risks-mitigations>...</ralph-risks-mitigations>
  <ralph-verification-strategy>...</ralph-verification-strategy>
</ralph-plan>

XML rules:
- Start with `<ralph-plan>` and end with `</ralph-plan>`
- No markdown fences
- Escape inline XML chars or use CDATA in code-blocks

Output only valid XML content to `{{PLAN_XML_PATH}}`.
