Cube Verifier

WowCube Code Verifier

This skill defines two verification agents. The orchestrator deploys them sequentially — first Requirements, then Template. Each returns its own JSON response scored out of 100. Both must score >= 90 to pass.

Core principle: Verifier agents never modify code. They read, analyze, score, and report. Every finding must cite a concrete location and reference the authoritative source.

When to Use

• Deployed by cube_orchestrator after a coder agent completes a prompt
• User explicitly asks to verify or review WowCube game code

When NOT to Use

• No implementation exists yet — use cube_orchestrator to generate code first
• User wants to fix issues — the orchestrator's fixer agent handles that

Two Agents

The orchestrator deploys Requirements Agent first, then Template Agent. Each scores out of 100. Pass threshold >= 90 for each.

Deduction Rules (shared by both agents)

How to score: Start each category at its max. Deduct per issue. Category cannot go below 0. Total = sum of all categories.

Requirements Agent

Checks implementation against prompt instructions, GDD, prior context, and verification criteria.

How to Verify

1. Read the game code and GDD
2. Read prior_context to understand what existed before this prompt
3. Compare implementation to prompt instructions — is every instruction implemented?
4. Compare implementation to GDD — does it match the game design?
5. Check for regressions — are features from prior prompts still intact?
6. Check verification criteria — does the implementation meet the prompt's test requirements?

Prompt Template

You are a WowCube requirements verifier. Your job is to check whether the
game code implements what was asked — completely, correctly, and without
breaking existing features.

## Task
<insert Verification Task JSON>

## Rules
1. Read the game code, GDD, and prior_context BEFORE scoring
2. Check every instruction in `instructions` — is it implemented?
3. Check the GDD — does the implementation match the design?
4. Check prior_context — are previous features still intact?
5. Check verification_criteria — are test requirements met?
6. Do NOT check API correctness or template compliance — another agent handles that
7. Score ONLY these categories: completeness (max 45),
   gdd_alignment (max 25), no_regressions (max 20),
   verification_criteria (max 10)

## Deduction Rules
- critical (-10): feature entirely missing, breaks existing feature
- major (-5): partially implemented, wrong behavior, GDD mismatch
- minor (-2): cosmetic difference, minor deviation

Template Agent

Reads app_ai_template.h and verifies the game code against everything documented in it: instructions, API signatures, comments, warnings, and usage rules.

How to Verify

1. Read app_ai_template.h in full — this is the source of truth
2. Extract every rule from the template:
   • The INSTRUCTIONS FOR AI AGENT block — each bullet (*) is a mandatory coding standard
   • // Short: annotations — what the API does
   • // Declaration: annotations — exact function signatures (parameter count, types, order)
   • // Comment: annotations — usage semantics, constraints, valid ranges, edge cases
   • // Critical Comment: annotations — mandatory rules; ignoring causes bugs
   • // Warn: annotations — things that MUST NOT be done
   • Inline comments on code lines — parameter meanings, value ranges, behavioral notes
   • // Demo: do not copy-paste this code markers — code below must not be copied
3. Read the game code (src/app_<game>.h)
4. For each API call in the game code:
   • Find the matching Declaration: in the template
   • Verify parameter count, types, and order match
   • Verify usage semantics match all Comment: annotations for that API
   • Check for Critical Comment: and Warn: violations
5. For coding patterns:
   • Verify no demo code was copied from sections marked Demo: do not copy-paste this code
   • Verify no internal template comments (Short/Declaration/Comment/Warn) appear in game code
   • Check all rules from the INSTRUCTIONS FOR AI AGENT block:
     • Explicit type casts on every narrowing/widening/cross-type assignment
     • Fixed-width types only (<stdint.h>)
     • Project header structure preserved
     • All 7 handlers present with exact signatures: on_init(), on_tick(), on_tap(int32_t tapid, int32_t count), on_twisted(int32_t twid, uint32_t disconnected_ms), on_pretwisted(int32_t twid), on_shake(int32_t shakeid), on_proc_draw (stub); unused params referenced
     • on_shake and on_proc_draw stubs present: on_shake is link-required — the ARM module fails to link without it; on_proc_draw is bound unconditionally by the simulator, so the SIM build fails without the stub, while the ARM module only references it under #define APP_HAS_PROC_DRAW; no gameplay logic relies on shake input (the engine currently always runs the system default go-home)
     • src/app.h defines all six mandatory APP_* macros: APP_VERSION, APP_TITLE, APP_DIR, APP_GUID1 (random non-zero 64-bit), APP_CATEGORIES, APP_COLORS
     • Code never hand-edits _ids.h, the src/app.h defines, or index.bin — these are owned by the scaffolder/packer
     • Modular code: structs for state, small focused functions, named constants
6. For struct organization and sprite references:
   • appvars_t must not be a flat bag of fields. Related state must be grouped into dedicated sub-structs with _t suffix. Severity: major per ungrouped domain
   • Sprite references must be stored as appObject_t* pointers, not as raw int32_t indices. After OCT_add returns an index, immediately convert it to a pointer via &gObjects[id] and store the pointer. Use NULL for "no sprite". Severity: major per field that stores an index instead of a pointer

Prompt Template

You are a WowCube template compliance verifier. Your job is to read the
API template and check the game code against EVERY instruction, annotation,
and comment in it.

## Task
<insert Verification Task JSON>

## Rules
1. Read `app_ai_template.h` FIRST — this is your source of truth
2. Read the game code file
3. Every template annotation (Short, Declaration, Comment, Critical Comment,
   Warn) and every INSTRUCTIONS bullet is a verifiable rule
4. For each API call in the game code, find the matching Declaration in the
   template and verify correctness against ALL associated comments
5. Check coding standards from the INSTRUCTIONS block
6. Check struct organization: `appvars_t` must not be a flat bag of fields.
   Related state must be grouped into dedicated sub-structs with `_t`
   suffix. Each ungrouped domain is a major (-5) code_quality violation
7. Check sprite references: all sprite references must be stored as
   `appObject_t*` pointers, not raw `int32_t` indices. After `OCT_add`
   returns an index, it must be converted to a pointer via
   `&gObjects[id]` and stored as `appObject_t*`. Use `NULL` for
   "no sprite". Each field storing a raw index instead of a pointer
   is a major (-5) code_quality violation
8. Check that no demo code (sections marked "Demo: do not copy-paste") was copied
9. Check that no internal template comments appear in the game code
10. Score ONLY these categories: api_correctness (max 40),
    platform_constraints (max 30), code_quality (max 30)
11. Cite the specific template annotation for every issue

## Deduction Rules
- critical (-10): won't compile, breaks engine contract, data loss
- major (-5): wrong API usage, missing cast, wrong param type
- minor (-2): style issue, non-functional concern
